Prostatectomía radical robot-asistida con preservación del espacio de Retzius: resultados perioperatorios y de continencia inmediata en una serie inicial / Retzius-sparing robot-assisted radical prostatectomy: Perioperative and immediate continence outcomes of an initial series

OBJETIVO: Los objetivos de este trabajo son presentar los resultados perioperatorios, de continencia inmediata y oncológicos iniciales en una serie de 25 pacientes con cáncer de próstata tratados con prostatectomía radical robot-asistida con preservación del espacio de Retzius. MATERIAL Y MÉTODOS: Analizamos retrospectivamente una serie de 25 pacientes tratados con prostatectomía radical robótica con preservación del espacio de Retzius por cáncer de próstata cT1-T2b entre 2018-2019. Se describen las 5 etapas de la cirugía. Efectuamos una estadística descriptiva de nuestra serie inicial y sus resultados en términos de continencia inmediata, definida como el uso de 0 compresas/pañales o 1 por seguridad/24 horas en la primera semana tras retirada de la sonda. RESULTADOS: Mediana de seguimiento, 6 meses (3-18). Mediana de PSA, 6,1 ng/ml (4-14,3). Todas las cirugías se realizan por vía posterior e intrafascial con preservación neurovascular bilateral en el 84% de los casos. El 28% tienen un margen quirúrgico afectado siendo el ápex la zona de afectación más frecuente. Complicaciones quirúrgicas: 1 (4%) paciente requirió transfusión de hemoderivados en el postoperatorio inmediato. Mediana de estancia hospitalaria 48 horas. Resultados funcionales: el 80% tiene continencia inmediata. El 80% de los continentes no requiere el uso de ningún pañal/compresa de seguridad. Resultados oncológicos: el 84% están libres de progresión bioquímica con una mediana de seguimiento de 6 meses. CONCLUSIONES: Los resultados funcionales iniciales en términos de continencia inmediata son muy satisfactorios en pacientes intervenidos de prostatectomía radical robótica con preservación del espacio de Retzius sin impacto negativo en el pronóstico

OBJECTIVE: The objective of this work is to present initial perioperative, immediate continence and oncological results in a series of 25 prostate cancer patients treated with Retzius-sparing robot-assisted radical prostatectomy. MATERIAL AND METHODS: We retrospectively analyzed a series of 25 patients treated with Retzius-sparing robot-assisted radical prostatectomy for cT1-T2b prostate cancer between 2018-2019. The 5 stages of surgery are described. We make a descriptive statistic of our initial series and its outcomes in terms of immediate continence, defined as the use of 0 pad/diapers or 1 safety pad/diaper every 24 hours, one week after catheter removal. RESULTS: Median follow-up, 6 months (3-18). Median PSA, 6.1 ng/ml (4-14.3). All surgeries were performed through a posterior intrafascial approach, and bilateral nerve-sparing was carried out in 84% of the cases. Affected surgical margins were present in 28%, being the apex the most frequent site of affectation. Surgical complications: 1 (4%) patient required transfusion of blood products in the immediate postoperative period. Mean hospital stay was 48 hours. Functional outcomes: 80% of the patients present immediate continence. 80% of continent patients do not require the use of any safety pads/diapers. Oncological outcomes: 84% are free of biochemical-progression in a median follow-up of 6 months. CONCLUSIONS: Initial functional results in terms of immediate continence are very satisfactory in patients who have undergone Retzius-sparing robot-assisted radical prostatectomy without negative impact on prognosis

Reconstrucción uretral en pacientes previamente tratados con endoprótesis uretral Memokath(TM) / Urethral reconstruction in patients previously treated with Memokath(TM) urethral endoprosthesis

Objetivo: Evaluar el papel y la tasa de éxito de la reconstrucción ureteral en pacientes con estenosis de uretra tratada previamente con endoprótesis uretral termoexpandible Memokath™. Material y método: Se presenta una serie de pacientes con estenosis de uretra y endoprótesis Memokath™ tratados con uretroplastia. La reconstrucción se decidió, bien debido a progresión de la estenosis, bien a complicaciones derivadas del tratamiento primario con el stent. Se evaluó la edad, la longitud de la estenosis y del stent, el tiempo entre la colocación del stent y la uretroplastia, el modo de retirada del stent, el tipo de uretroplastia, las complicaciones y los parámetros miccionales antes y después de la uretroplastia. Se considera resultado exitoso conseguir la micción espontánea sin necesidad de procedimiento postoperatorio. Resultados: Se incluyeron 8 casos con estenosis de uretra bulbar. Memokath™ se retiró endoscópicamente antes de la uretroplastia en 6 casos (75%) y mediante uretrotomía abierta en el momento de la uretroplastia en 2 (25%). La técnica de uretroplastia fue: injerto de mucosa bucal onlay dorsolateral en 5 casos (62,5%) y escisión con anastomosis primaria, uretroplastia anastomótica e injerto de mucosa bucal onlay dorsal en un caso (12,5%) cada uno. No hubo ningún fracaso con una mediana de seguimiento de 26 ± 21,5 meses. El IPSS total, la CdV, el Qmáx y el residuo postmiccional mejoraron significativamente (p < 0,05). Como complicación, un paciente (12,5%) presentó epididimitis y acortamiento peneano. Conclusiones: La uretroplastia tras reestenosis u otras complicaciones en pacientes con stent uretral temporal Memokath™ es una opción de reconstrucción viable y definitiva con excelentes resultados a corto plazo y pocas complicaciones. El injerto de mucosa bucal onlay dorsolateral de un solo lado es la técnica óptima para esta indicación

Purpose: To evaluate the role and success rate of urethral reconstruction in patients with urethral stricture previously treated with thermos-expandable Memokath™ urethral endoprosthesis. Materials and method: A case series of patients with urethral stricture and Memokath™ endoprosthesis treated with urethroplasty is presented. Reconstruction was decided due to stricture progression or complications derived from primary stent treatment. Age, stricture and stent length, time between stent placement and urethroplasty, mode of stent retrieval, type of urethroplasty, complications and voiding parameters before and after urethroplasty were evaluated. Successful outcome was defined as standard voiding, without need of any postoperative procedure. Results: Eight cases with bulbar urethra stricture were included. Memokath™ was endoscopically retrieved before urethroplasty in 6 (75%) and by open urethrotomy at the time of urethroplasty in 2 (25%). Technique of urethroplasty was dorso-lateral onlay buccal mucosa graft in 5 (62.5%) cases and excision and primary anastomosis, anastomotic urethroplasty, and dorsal onlay buccal mucosa graft in one (12.5%) case each. There was no failure at 26 ± 21.5 months median follow-up. Total IPSS, QoL, Qmax and postvoid residual significantly improved (P < .05). The only complication presented was epididymitis and penile shortening in one patient (12.5%). Conclusions: Urethroplasty after re-stricture or other complications in patients with temporary Memokath™ urethral stent is a viable and definite option of reconstruction with excellent results in the short term and few complications. One-side dorsolateral onlay buccal mucosa graft augmentation is the optimal technique for this indication

Tratamiento de la incontinencia urinaria de esfuerzo tras prostatectomía con el sistema masculino transobturador ajustable (ATOMS(R)) con puerto escrotal premontado / Treatment of stress urinary incontinence after prostatectomy with the adjustable transobturator male system (ATOMS(R)) with preattached scrotal port

Introducción: La incontinencia urinaria de esfuerzo (IUE) es una secuela importante del tratamiento quirúrgico del cáncer de próstata. Se presenta la técnica quirúrgica y se evalúa efectividad y seguridad del sistema masculino transobturador ajustable (ATOMS(R)) con puerto escrotal premontado. Material y método: Estudio abierto prospectivo realizado en un hospital universitario. El objetivo principal fue cambio de situación basal tras ajuste en el recuento diario de compresas (pad-count) y su peso húmedo (pad-test). Los objetivos secundarios fueron evaluación de calidad de vida (ICIQ-SF e IIQ-7 basal y al ajuste), resultados percibidos por el paciente (PGI y GRA al año) y evaluación de complicaciones según Clavien-Dindo. Los valores numéricos se expresan en mediana + RIC. Resultados: Se analizan 60 pacientes consecutivos con seguimiento de 21+22 meses. El pad-test basal fue 465 + 450 ml y pad-count 5 + 3 compresas/día. La IUE basal fue leve (11,6%), moderada (25%) y severa (63,3%). El tiempo operatorio fue 60 + 25 min, la estancia hospitalaria 1+0 días y la EVA de dolor en día-1 postoperatorio 0 + 1. El llenado total fue 16,5+7ml y el número de rellenos 1+2. Pad-test y pad-count tras ajuste fueron 0 + 20 ml y 0+1, respectivamente (ambos p<0,0001 respecto a basal). La IUE desapareció (81,7%) o se mantuvo leve (11,7%), moderada (5%) y severa (1,6%). Se objetivó reducción en ICIQ-SF (p < 0,0001) e IIQ-7 (p = 0,0003). Tanto la continencia (p=0,002) como la satisfacción (p = 0,03) resultaron peores en pacientes irradiados. Sucedieron complicaciones en 11 casos (18,6%), siendo 8(13,5%) grado I y 3(5,1%) grado III. La tasa de satisfacción con el tratamiento fue 91,7% y la percepción de mejoría global percibida por el paciente al año fue muy marcada (score PGI-I 1+1 y GRA 6+1). Conclusiones: El tratamiento de la IUE masculina con ATOMS(R) tercera generación es seguro y eficaz a corto plazo, incluso en pacientes con IUE severa. La tasa de pacientes secos tras el ajuste supera el 80% y la tasa de satisfacción el 90%. Los pacientes valoran muy positivamente este tratamiento

Introduction: Stress urinary incontinence (SUI) is a significant sequela of prostate cancer surgery. In this article, we present the surgical technique and safety and efficacy of the adjustable transobturator male system (ATOMS(R)) with preattached scrotal port. Material and method: An open prospective study was conducted at a university hospital with the main objective of changing the baseline condition after adjustment in the daily pad count and their wet weight (pad test). The secondary objectives were the quality-of-life assessment (International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF] and Incontinence Impact Questionnaire-7 [IIQ-7], baseline and after the adjustment), patient-perceived results (Patient Global Index [PGI] and Global Response Assessment [GRA] at 1 year) and assessment of complications according to Clavien-Dindo. The numerical values are expressed in median ± IQR. Results: We analysed 60 consecutive patients with a follow-up of 21 ± 22 months. The baseline pad-test was 465 ± 450 mL, and the pad-count was 5 + 3 pads/day. The baseline SUI was mild (11.6% of patients), moderate (25%) and severe (63.3%). The operative time was 60 ± 25 min, the hospital stay was 1 ± 0 days, and the visual analogue scale of pain on day 1 after surgery was 0 ± 1. The total filling was 16.5 ± 7 mL, and the number of refillings was 1 ± 2. The pad-test and pad-count after the adjustment were 0 ± 20 mL and 0±1, respectively (both p < .0001 compared with baseline). SUI disappeared (81.7%) or remained mild (11.7%), moderate (5%) or severe (1.6%). We observed a reduction in the ICIQ-SF (p < .0001) and IIQ-7 scores (p = .0003). Both continence (p=.002) and satisfaction (p = .03) were lower in the irradiated patients. Complications occurred in 11 cases (18.6%), 8 (13.5%) of which were grade I and 3 (5.1%) of which were grade 3. The treatment satisfaction rate was 91.7%, and the patient-perceived overall improvement at 1 year was highly pronounced (PGI-I score, 1 ± 1; GRA, 6 ± 1). Conclusions: SUI treatment of men using third-generation ATOMS(R) is safe and effective in the short-term, even in patients with severe SUI. The rate of dry patients after the adjustment exceeded 80%, and the satisfaction rates exceeded 90%. The patients assessed this treatment highly positively

Estudio prospectivo comparativo entre cistectomía radical laparoscópica y abierta: resultados operatorios y oncológicos / Prospective study comparing laparoscopic and open radical cystectomy: Surgical and oncological results

Introducción La cistectomía radical laparoscópica con linfadenectomía y derivación urinaria es una cirugía de empleo creciente. Se necesitan estudios que avalen la efectividad oncológica y la seguridad de este abordaje mínimamente invasivo. Pacientes y métodos: Estudio prospectivo comparativo no aleatorizado entre cistectomía radical abierta (CRA) y laparoscópica (CRL) llevado a cabo en un hospital universitario. El objetivo principal fue comparar la supervivencia cáncer-específica, y el objetivo secundario comparar resultados operatorios y complicaciones según la escala Clavien-Dindo. Resultados: Ciento cincuenta y seis pacientes con cáncer vesical invasivo de alto grado fueron tratados mediante CRA (n = 70) o CRL (n = 86). El seguimiento medio fue 33,5 ± 23,8 (rango 12-96) meses. La edad media fue 66,9 + 9,4 años y la proporción hombre/mujer 19:1. Ambos grupos fueron equivalentes en edad, estadio, ganglios positivos, carcinoma in situ, uropatía obstructiva preoperatoria, quimioterapia adyuvante y tipo de derivación urinaria. No hubo diferencias entre grupos en supervivencia cáncer-específica (log-rank; p = 0,71). El estadio histopatológico fue la única variable independiente predictiva de pronóstico. La estancia hospitalaria (p = 0,01) y la tasa de transfusión operatoria (p = 0,002) fueron menores para CRL. La duración de la cirugía fue mayor para CRL (p < 0,001). No hubo diferencias en la tasa de complicaciones totales (p = 0,62) ni complicaciones mayores (p = 0,69). El riesgo de evisceración (p = 0,02), infección de herida quirúrgica (p = 0,005) y neumonía (p = 0,017) fue mayor en CRA. El riesgo de lesión rectal (p = 0,017) y fístula uretrorrectal (p = 0,065) fue mayor en CRL. Conclusión: La CRL es un tratamiento equivalente a la CRA en términos de eficacia oncológica, y ventajoso respecto a tasa de transfusión y estancia hospitalaria, pero no respecto a la ocupación de quirófano o a la seguridad global. Se necesitan estudios que definan mejor el perfil de seguridad específico de cada abordaje

Introduction: Laparoscopic radical cystectomy with lymphadenectomy and urinary diversion is an increasingly widespread operation. Studies are needed to support the oncological effectiveness and safety of this minimally invasive approach. Patients and methods: A nonrandomised, comparative prospective study between open radical cystectomy (ORC) and laparoscopic radical cystectomy (LRC) was conducted in a university hospital. The main objective was to compare cancer-specific survival. The secondary objective was to compare the surgical results and complications according to the Clavien-Dindo scale. Results: We treated 156 patients with high-grade invasive bladder cancer with either ORC (n = 70) or LRC (n = 86). The mean follow-up was 33.5 ± 23.8 (range 12-96) months. The mean age was 66.9 + 9.4 years, and the male to female ratio was 19:1. Both groups were equivalent in age, stage, positive lymph nodes, in situ carcinoma, preoperative obstructive uropathy, adjuvant chemotherapy and type of urinary diversion. There were no differences between the groups in terms of cancer-specific survival (log-rank; P = .71). The histopathology stage was the only independent variable that predicted the prognosis. The hospital stay (P = .01) and operative transfusion rates (P = .002) were less for LRC. The duration of the surgery was greater for LRC (P < .001). There were no differences in the total complications rate (p = .62) or major complications (P = .69). The risk of evisceration (P = .02), surgical wound infection (P=.005) and pneumonia (P = .017) was greater for ORC. The risk of rectal lesion (P = .017) and urethrorectal fistulae (P = .065) was greater for LRC. Conclusion: LRC is an equivalent treatment to ORC in terms of oncological efficacy and is advantageous in terms of transfusion rates and hospital stays but not in terms of operating room time and overall safety. Studies are needed to better define the specific safety profile for each approach

Eficacia de la terapia de ondas de choque de baja intensidad para la disfunción eréctil: revisión sistemática y metaanálisis / Efficacy of low-intensity shock wave therapy for erectile dysfunction: A systematic review and meta-analysis

Contexto: La terapia con ondas de choque de baja intensidad (OCBI) es una modalidad de reciente uso en el tratamiento de la disfunción eréctil. Objetivo: Evaluar la eficacia de la terapia con OCBI para el tratamiento de la disfunción eréctil según se describe en la literatura. Adquisición de evidencia: Dos revisores independientes identificaron estudios elegibles para llevar a cabo revisión sistemática y metaanálisis de diferentes fuentes escritas en inglés y español, utilizando las bases de datos de PubMed, Embase y Web of Science. Se excluyeron los estudios sobre la enfermedad de Peyronie. Se utilizó el método Der Simonian-Laird para definir la heterogeneidad calculando la desviación estándar de la media (DME) agrupada. El objetivo primario de esta revisión es evaluar la eficacia según el cambio del Índice internacional de función eréctil (IIEF-EF) sobre basal al mes de inicio de tratamiento, tanto para el brazo de tratamiento como para el brazo placebo. El objetivo secundario se centra en analizar IIEF-EF a 3-6 meses tras el inicio de la terapia. Síntesis de evidencia: Los datos agrupados de 636 pacientes procedentes de 12 estudios mostraron que el tratamiento con OCBI conlleva un aumento significativo de IIEF-EF al mes con respecto a basal (DME = -2,92; p = 0,000), en un grado mayor que placebo (DME = -0,99; p = 0,000). El IIEF-EF a 3-6 meses en pacientes tratados fue significativamente mayor que basal (DME = -2,78; p = 0,000). Solo hay un estudio que compara eficacia de placebo a 3-6 meses vs basal (DME = -9,14). La comparación entre OCBI y placebo favorece el tratamiento activo (DME = 2,53; p = 0,000) al mes. No existen datos suficientes para evaluar respuesta sobre placebo a los 3-6 meses en la literatura. Conclusiones: El tratamiento con OCBI para la disfunción eréctil según la literatura resulta eficaz, tanto a corto como a medio plazo. A corto plazo se ha descrito incluso más eficaz que placebo. Los datos sobre eficacia a largo plazo son insuficientes. También se necesitan más estudios para dilucidar el papel de esta terapia según las causas específicas de la disfunción eréctil

Context: The low-intensity shockwave (LISW) therapy is a recently developed modality for treating erectile dysfunction. Objective: To assess the efficacy of LISW therapy for treating erectile dysfunction as described in the literature. Acquisition of evidence: Two independent reviewers identified studies eligible for a systematic review and meta-analysis of various sources written in English and Spanish, using the databases of PubMed, EMBASE and Web of Science. We excluded studies on Peyronie's disease. We employed the DerSimonian-Laird method for defining heterogeneity, calculating the grouped standard deviation of the mean (SDM). The primary objective of this review is to assess efficacy based on the change in the International Index of Erectile Function (IIEF-EF) over baseline at 1 month from the start of treatment, both for the treatment arm and the placebo arm. The secondary objective is focused on analysing IIEF-EF at 3- 6 months from the start of the therapy. Summary of the evidence: The pooled data of 636 patients from 12 studies showed that treatment with LISW resulted in a significant increase in IIEF-EF at 1 month with respect to baseline (SDM, -2.92; P = .000), to a greater degree than placebo (SDM, -.99; P = .000). The IIEF-EF at 3-6 months for the treated patients was significantly greater than baseline (SDM, -2.78; P = .000). Only one study compared the efficacy of placebo at 3-6 months versus baseline (SDM, -9.14). The comparison between LISW and placebo favours active treatment (SDM, 2.53; P = .000) at 1 month. There are insufficient data in the literature to assess the response over placebo at 3-6 months. Conclusions: According to the literature, treatment with LISW for erectile dysfunction is effective, both in the short and medium term. LISW has been described as more effective than placebo in the short term. The long-term efficacy data are insufficient. More studies are needed to explain the role of this therapy according to specific causes of erectile dysfunction

Reconstrucción fálica total con colgajo libre antebraquial radial tras amputación peneana iatrogénica / Total phallic reconstruction using radial forearm free flap after iatrogenic penile amputation

Introducción: La pérdida del pene de causa iatrogénica es una circunstancia muy infrecuente. Se presenta un caso desafiante de reconstrucción peneana total diferida en varón genético. Material y métodos: Varón de 57 años con pérdida del falo por absceso peneano y necrosis secundaria a cirugía de incurvadura peneana. La reconstrucción se realizó en varios tiempos empleando colgajo libre de antebrazo radial (CLAR) y colocación de prótesis inflable personalizada un año después. Resultados: En un primer tiempo quirúrgico se llevó a cabo drenaje de absceso peneano, desbridamiento de restos necróticos y colocación de talla hipogástrica. Siete semanas después se llevó a cabo faloplastia con CLAR y construcción de neouretra tubo-en-tubo, anastomosis microquirúrgica múltiple y recubrimiento del sitio donante con injerto de piel del muslo de espesor parcial. La duración de esta cirugía fue 10 horas y tuvo como complicación crecimiento de vello en la neouretra, que obligó a depilación mecánica endoscópica en repetidas ocasiones. El paciente recuperó sensibilidad peneana, y 18 meses tras la faloplastia se le implantó prótesis Zephyr (Ginebra, Suiza) inflable de un solo cuerpo, utilizando la propia albugínea del cuerpo cavernoso proximal. El paciente se encuentra satisfecho desde el punto de vista cosmético, miccional y sensitivo. Cuatro meses después se encuentra ganando confianza para abordar la penetración. Conclusiones: A pesar del riesgo de complicaciones postoperatorias y de la necesidad de operaciones múltiples, la reconstrucción fálica con CLAR y colocación de implante protésico personalizado puede mejorar el impacto en la función urinaria y sexual secundario a la pérdida del pene

Introduction: The iatrogenic loss of the penis is a rare situation. We present a challenging case of deferred total penile reconstruction in a genetic male. Material and methods: A 57-year-old man with the loss of the penis due to a penile abscess and necrosis secondary to penile curvature surgery. The reconstruction was performed over several operations using a radial forearm free flap (RFFF) and placement of a customised inflatable prosthesis a year later. Results: During the first operation, the penile abscess was drained, the necrotic residues were debrided and placement of hypogastric drainage. Seven weeks later, phalloplasty was performed with RFFF and a tube-in-tube neourethra was constructed. Multiple microsurgical anastomosis was performed, and the donor site was coated with a skin graft from the thigh of partial thickness. The surgery lasted 10 hours and had the complication of hair growth in the neourethra, which required mechanical endoscopic depilation on repeated occasions. The patient regained penile sensitivity. Eighteen months after the phalloplasty, a Zephyr single-body inflatable prosthesis (Geneva, Switzerland) was implanted, using the tunica albuginea of the proximal corpus cavernosum. The patient was satisfied with the aesthetics and urinary and sensory function. Four months later, the patient is gaining confidence to consider penetration. Conclusions: Despite the risk of postoperative complications and the need for multiple operations, phallic reconstruction with RFFF and the placement of a customised prosthetic implant can improve urinary and sexual function secondary to the loss of the penis

Análisis comparativo entre nefrectomía parcial LESS híbrida y laparoscópica convencional multipuerto / Comparative study of hybrid laparoendoscopic single-site (LESS) partial nephrectomy and conventional multiport laparoscopy

Objetivo: Comparar resultados operatorios y oncológicos de la nefrectomía parcial realizada mediante abordaje laparoendoscópico a través de puerto único (LESS) reutilizable y laparoscópico multipuerto. Material y método: Estudio comparativo prospectivo pareado no aleatorizado de pacientes tratados con nefrectomía parcial mediante abordaje LESS híbrido con trocar auxiliar de 3,5 mm (n = 20) y con laparoscopia multipuerto convencional (n = 26). Resultados: La media de seguimiento fue 31 ± 18,6 meses. Un caso LESS (5%) se reconvirtió a laparoscopia. No hubo diferencias significativas entre grupos con respecto a edad, sexo, índice de masa corporal, lateralidad, localización, tamaño tumoral o empleo de doble-J; aunque hubo dominancia de ASA-I (p = 0,09) y de histología benigna (p = 0,05) en el grupo LESS. Tampoco hubo diferencias en tiempo operatorio, tiempo de isquemia, empleo de materiales hemostáticos, sangrado estimado, hemoglobina postoperatoria, transfusión u otras complicaciones. Ningún caso precisó ampliar herida cutánea para extracción de espécimen. Los pacientes LESS tuvieron menor tiempo de drenaje (p = 0,006) y menor estancia hospitalaria (p = 0,003). No hubo diferencias en número ni severidad de complicaciones según escala Clavien-Dindo. Un paciente en grupo laparoscópico falleció por TEP tras el alta hospitalaria. No hubo márgenes positivos ni recidivas o progresión de la enfermedad tumoral en el tiempo evaluado. Conclusiones: La nefrectomía parcial LESS no implica ventajas en resultados operatorios salvo menor estancia hospitalaria, posiblemente debido a hemostasia operatoria más precisa y/o selección de casos. No conlleva riesgos operatorios y oncológicos, pero tampoco supone mejora en tiempo de isquemia, pérdida hemática o tasa de transfusión. Tampoco supone una ventaja evidente en términos cosméticos

Objective: To investigate the surgical and oncological outcomes of hybrid laparoendoscopic single-site (LESS) in partial nephrectomy with reusable components compared with multiport laparoscopy. Material and method: Hybrid LESS technique with auxiliary 3.5mm trocar (n = 20) was compared with conventional multiport laparoscopy (n = 26) by a prospective, paired, nonrandomized, and comparative study in partially nephrectomized patients. Results: Follow-up average was 31 ± 18.6 months. In one case, LESS was converted to laparoscopy. No differences were found regarding age, sex, body mass index, laterality, localization, tumor size or use of double J stent. Dominance of Loop-I (P = 0.09) and benign histology (P = 0.05) were observed in the LESS group. Neither there were differences regarding operating time, ischemia time, use of hemostatic materials, estimated blood loss, postoperative hemoglobin levels, transfusion or other complications. In any case, to extend the skin incision for specimen extraction was not necessary. Drainage time (P = 0.006) and hospital stay (P = 0.003) were better in LESS patients. Concerning complications, no significant differences were observed according Clavien-Dindo scale. In laparoscopic group one patient died of pulmonary embolism after hospital discharge. No positive margins were observed in any case. During follow-up neither tumor recurrence nor disease progression were observed. Conclusions: Regarding surgical outcomes, partial nephrectomy by LESS technique does not imply improvements, excepting shorter hospital stay, probably due to accurate surgical hemostasis and/or selection of cases. No surgical and oncological risks are involved, as well as no improvement in ischemia time, blood loss or transfusion rate. We find no significant difference in cosmetic outcomes

Tratamiento de la estenosis larga de uretra anterior asociada a liquen escleroso / Treatment of long anterior urethral stricture associated to lichen sclerosus

Introducción. La estenosis panuretral asociada a liquen escleroso supone un reto terapéutico. Presentamos el análisis de nuestros resultados empleando 2 técnicas de uretroplastia basadas en injerto de mucosa oral. Material y método. Estudio retrospectivo en pacientes con estenosis larga de uretra anterior (>8cm) asociada a liquen escleroso. Los pacientes recibieron uretroplastia con injerto de mucosa oral según técnica de Kulkarni (n=25) o uretroplastia en 2 tiempos tipo Bracka-Johanson (n=15). Se evalúan datos demográficos, tiempo operatorio, complicaciones (Clavien-Dindo), estancia hospitalaria, EAV de dolor postoperatorio, tasa de fracaso, necesidad de retratamiento y datos funcionales que incluyen IPSS, CdV y Qmáx, residuo posmiccional (RPM). Resultados. En todos los casos hubo afectación glandular y peneana y en el 75% de uretra bulbar. En el 22,5% se empleó un solo injerto, en el 72,5% 2 y en el 5% 3. Los pacientes tratados en un solo tiempo fueron más jóvenes (p=0,007). A pesar de que la longitud de la estenosis fue equivalente en ambas técnicas (p=0,96), la tasa de recidiva y de complicaciones fue superior en 2 tiempos (p=0,05 y p=0,03; respectivamente), así como el tiempo operatorio (p<0,0001) y la estancia global (p=0,0002). No hubo diferencias en IPSS, CdV, Qmáx o RPM preoperatorios, ni tampoco en los valores postoperatorios de IPSS o Qmáx; pero sí en CdV (p=0,006) y RPM (p=0,03) a favor de uretroplastia en un tiempo. La EAV de dolor en el 1.er día postoperatorio fue también menor en la uretroplastia de Kulkarni que en el primer tiempo de Johanson-Bracka (p<0,0001). Conclusiones. En pacientes con liquen escleroso y estenosis larga de uretra anterior la uretroplastia de Kulkarni proporciona resultados operatorios más eficientes y mejor valorados por el paciente que la uretroplastia de Johanson-Bracka. Además, evita el deterioro temporal cosmético, sexual y miccional inherente a la cirugía en 2 tiempos (AU)

Introduction. Panurethral stricture associated with lichen sclerosus is a therapeutic challenge. We present the analysis of our results using two urethroplasty techniques based on oral mucosa graft. Material and method. Retrospective study in patients with long anterior urethral stricture (>8cm) associated with lichen sclerosus. Patients received urethroplasty with oral mucosa graft technique according Kulkarni (n=25) or two-step Johanson-Bracka urethroplasty (n=15). Demographics, operative time, complications (Clavien-Dindo), hospital stay, days with catheter, EAV postoperative pain, failure rate, need for retreatment and functional data including IPSS, QoL, Qmax, post void residual (PVR) are evaluated. Results. In all cases there was involvement of glandular and penile urethra, and in 75% of bulbar urethra. A single graft was used in 22.5%, two in 72.5% and three in 5%. Patients treated at a single step were younger (P=.007). Although the length of the stenosis was equivalent in both techniques (P=.96), relapse and complication rates were higher in two-step surgery (P=.05 and P=.03; respectively) and so was operative time (P<.0001) and overall stay (P=.0002). There were no differences in preoperative IPSS, QoL, Qmax or PVR, neither in postoperative values of IPSS or Qmax; but there was a difference in QoL (P=.006) and PVR (P=.03) favouring single-step urethroplasty. VAS pain on postoperative day 1 was also lower in Kulkarni urethroplasty than in the first step of Johanson-Bracka technique (P<.0001). Conclusions. In patients with lichen sclerosus and long anterior urethral stricture Kulkarni urethroplasty provides more efficient and better patient reported outcomes than Johanson-Bracka urethroplasty. It also prevents cosmetic, sexual and voiding temporary deterioration inherent to 2-step surgery (AU)

Total phallic reconstruction using radial forearm free flap after iatrogenic penile amputation. / Reconstrucción fálica total con colgajo libre antebraquial radial tras amputación peneana iatrogénica.

INTRODUCTION: The iatrogenic loss of the penis is a rare situation. We present a challenging case of deferred total penile reconstruction in a genetic male. MATERIAL AND METHODS: A 57-year-old man with the loss of the penis due to a penile abscess and necrosis secondary to penile curvature surgery. The reconstruction was performed over several operations using a radial forearm free flap (RFFF) and placement of a customised inflatable prosthesis a year later. RESULTS: During the first operation, the penile abscess was drained, the necrotic residues were debrided and placement of hypogastric drainage. Seven weeks later, phalloplasty was performed with RFFF and a tube-in-tube neourethra was constructed. Multiple microsurgical anastomosis was performed, and the donor site was coated with a skin graft from the thigh of partial thickness. The surgery lasted 10hours and had the complication of hair growth in the neourethra, which required mechanical endoscopic depilation on repeated occasions. The patient regained penile sensitivity. Eighteen months after the phalloplasty, a Zephyr single-body inflatable prosthesis (Geneva, Switzerland) was implanted, using the tunica albuginea of the proximal corpus cavernosum. The patient was satisfied with the aesthetics and urinary and sensory function. Four months later, the patient is gaining confidence to consider penetration. CONCLUSIONS: Despite the risk of postoperative complications and the need for multiple operations, phallic reconstruction with RFFF and the placement of a customised prosthetic implant can improve urinary and sexual function secondary to the loss of the penis.

Efficacy of low-intensity shock wave therapy for erectile dysfunction: A systematic review and meta-analysis. / Eficacia de la terapia de ondas de choque de baja intensidad para la disfunción eréctil: revisión sistemática y metaanálisis.

CONTEXT: The low-intensity shockwave (LISW) therapy is a recently developed modality for treating erectile dysfunction. OBJECTIVE: To assess the efficacy of LISW therapy for treating erectile dysfunction as described in the literature. ACQUISITION OF EVIDENCE: Two independent reviewers identified studies eligible for a systematic review and meta-analysis of various sources written in English and Spanish, using the databases of PubMed, EMBASE and Web of Science. We excluded studies on Peyronie's disease. We employed the DerSimonian-Laird method for defining heterogeneity, calculating the grouped standard deviation of the mean (SDM). The primary objective of this review is to assess efficacy based on the change in the International Index of Erectile Function (IIEF-EF) over baseline at 1 month from the start of treatment, both for the treatment arm and the placebo arm. The secondary objective is focused on analysing IIEF-EF at 3-6 months from the start of the therapy. SUMMARY OF THE EVIDENCE: The pooled data of 636 patients from 12 studies showed that treatment with LISW resulted in a significant increase in IIEF-EF at 1 month with respect to baseline (SDM, -2.92; P=.000), to a greater degree than placebo (SDM, -.99; P=.000). The IIEF-EF at 3-6 months for the treated patients was significantly greater than baseline (SDM, -2.78; P=.000). Only one study compared the efficacy of placebo at 3-6 months versus baseline (SDM, -9.14). The comparison between LISW and placebo favours active treatment (SDM, 2.53; P=.000) at 1 month. There are insufficient data in the literature to assess the response over placebo at 3-6 months. CONCLUSIONS: According to the literature, treatment with LISW for erectile dysfunction is effective, both in the short and medium term. LISW has been described as more effective than placebo in the short term. The long-term efficacy data are insufficient. More studies are needed to explain the role of this therapy according to specific causes of erectile dysfunction.

Comparative study of hybrid laparoendoscopic single-site (LESS) partial nephrectomy and conventional multiport laparoscopy. / Análisis comparativo entre nefrectomía parcial LESS híbrida y laparoscópica convencional multipuerto.

OBJECTIVE: To investigate the surgical and oncological outcomes of hybrid laparoendoscopic single-site (LESS) in partial nephrectomy with reusable components compared with multiport laparoscopy. MATERIAL AND METHOD: Hybrid LESS technique with auxiliary 3.5mm trocar (n=20) was compared with conventional multiport laparoscopy (n=26) by a prospective, paired, nonrandomized, and comparative study in partially nephrectomized patients. RESULTS: Follow-up average was 31±18.6 months. In one case, LESS was converted to laparoscopy. No differences were found regarding age, sex, body mass index, laterality, localization, tumor size or use of double J stent. Dominance of Loop-I (P=0.09) and benign histology (P=0.05) were observed in the LESS group. Neither there were differences regarding operating time, ischemia time, use of hemostatic materials, estimated blood loss, postoperative hemoglobin levels, transfusion or other complications. In any case, to extend the skin incision for specimen extraction was not necessary. Drainage time (P=0.006) and hospital stay (P=0.003) were better in LESS patients. Concerning complications, no significant differences were observed according Clavien-Dindo scale. In laparoscopic group one patient died of pulmonary embolism after hospital discharge. No positive margins were observed in any case. During follow-up neither tumor recurrence nor disease progression were observed. CONCLUSIONS: Regarding surgical outcomes, partial nephrectomy by LESS technique does not imply improvements, excepting shorter hospital stay, probably due to accurate surgical hemostasis and/or selection of cases. No surgical and oncological risks are involved, as well as no improvement in ischemia time, blood loss or transfusion rate. We find no significant difference in cosmetic outcomes.

Láser resección transuretral prostática: estudio de seguridad con un nuevo sistema de fotovaporización selectiva con láser de diodo de alta intensidad en próstatas mayores de 80 ml / Laser transurethral resection of the prostate: Safety study of a novel system of photoselective vaporization with high power diode laser in prostates larger than 80 mL

Objetivo: Presentar la viabilidad de la vaporización fotoselectiva de la próstata (VFP) con un nuevo sistema de resección de láser de diodo. El tratamiento quirúrgico de la hiperplasia prostática benigna (HPB) está en constante evolución. Las técnicas de láser se utilizan cada vez más en próstatas de gran tamaño. Métodos: Se realizó un estudio prospectivo para evaluar los datos operativos y los resultados de los pacientes con VFP utilizando láser de diodo de alta potencia (DAP) y una innovadora fibra con cabeza de cuarzo en forma de pala en los pacientes con próstata > 80 ml. Se describen los datos demográficos, tiempo quirúrgico, pérdida de hemoglobina, resultados operatorios (IPSS, calidad de vida [CdV], Qmáx, residuo posmiccional [RPM], IIEF-5 y micción diaria) y las complicaciones de la clasificación Clavien-Dindo. Resultados: Treinta y un pacientes fueron incluidos en el estudio. Dieciséis (51,6%) estaban en tratamiento antiplaquetario activo y 12 (38,7%) habían recibido anticoagulantes antes de la cirugía. Todos los casos fueron seguidos al menos 6 meses. No se produjeron complicaciones graves intraoperatorias ni postoperatorias. Tres pacientes (9,7%) tuvieron complicaciones leves según la clasificación Clavien-Dindo. Veintisiete (87,1%) fueron dados de alta en el primer día del postoperatorio sin catéter. Hubo mejoras significativas en el IPSS, CdV, Qmáx y RPM, tanto a los 3 como a los 6 meses (p < 0,0001), pero la función sexual según el IIEF-5 no mostró diferencias. La urgencia (de cualquier grado) aumentó a los 3 meses (48,4%; p = 0,002) y se redujo considerablemente a los 6 meses (9,7%, p < 0,0001). Conclusión: Esta experiencia piloto con fibra en forma de pala y DAP es alentadora. Esto demuestra que la resección con láser es un procedimiento seguro, logrando excelentes resultados en cuanto a IPSS, CdV y Qmáx en próstatas grandes, incluso en pacientes de alto riesgo. Se necesita un seguimiento más prolongado, estudios controlados comparativos y aleatorios para generalizar estos resultados

Objective: To present the feasibility of photoselective vaporization of the prostate (PVP) with of a new diode laser-resection system. Surgical treatment of benign prostatic hyperplasia (BPH) is constantly evolving. Laser techniques are increasingly used in prostates of large size. Methods: A prospective study was performed to evaluate operative data and patient outcomes with PVP using high-power diode laser (HPD) and a novel quartz-head fiber with shovel shape in patients with prostate > 80 mL. Demographic data, operative time, hemoglobin loss, operative results (IPSS, quality of life (QoL), Qmax, post void residue (PVR), IIEF-5 and micturition diary) and complications following Clavien-Dindo classification are described. Results: Thirty-one patients were included in the study. Sixteen (51.6%) were on active antiplatelet treatment and 12 (38.7%) had received anticoagulants before surgery. All cases were followed at least 6 mo. No intraoperative or postoperative major complications occurred. Three patients (9.7%) had minor complications according to Clavien-Dindo classification. Twenty-seven (87.1%) were discharged on postoperative day one without catheter. There were significant improvements in IPSS, QoL, Qmax and PVR, both at 3 and 6 mo (P < .0001), but sexual function according to IIEF-5 showed no differences. Urgency (any grade) increased at 3 mo (48.4%; P = .002) and considerably decreased at 6 mo (9.7%;P < .0001). Conclusion: This pilot experience with shovel shape fiber and HPD is encouraging. It shows that laser-resection is a safe procedure, achieving excellent results in terms of IPSS, QoL and Qmax in large prostates even in high-risk patients. Longer follow-up, comparative and randomized controlled studies are needed to widespread these results

La opción óptima: nefrectomía radical LESS umbilical con extracción vaginal / The best option: Umbilical LESS radical nephrectomy with vaginal extraction

Introducción: La cirugía laparoendoscópica a través de puerto único (LESS) umbilical constituye una excelente alternativa a la cirugía laparoscópica o robótica multipuerto. Ofrece precoz recuperación, menos dolor postoperatorio y óptimo resultado cosmético. La naturaleza reutilizable de los instrumentos implica también importantes ventajas económicas. Paciente y método: Presentamos una paciente de 34 años con lesión sólida mesorrenal de 8 cm en riñón izquierdo tratada con nefrectomía radical LESS pura asistida por extracción vaginal del espécimen. El abordaje umbilical a través de dispositivo de puerto único multicanal KeyPort (Richard Wolf GmbH, Knittingen, Alemania) con instrumentos curvos DuoRotate permite mínimo agolpamiento y/o conflicto de espacio. Su perfecta adaptación umbilical proporciona un sistema estanco. La doble rotación del instrumental consigue gran precisión de movimientos. La extracción vaginal respeta la pared abdominal y evita la necesidad de ampliar la incisión umbilical. Resultados: Tras la colocación del dispositivo y la triangulación de las pinzas se procedió a incidir el peritoneo parietal posterior. El colon descendente fue movilizado para acceder al retroperitoneo y disecar el hilio renal. Se colocaron Hem-o-loks en arteria y vena, que posteriormente fueron seccionadas. La pieza se introdujo en bolsa laparoscópica. Bajo visión directa se colocó trócar de 15 mm a través del fondo del saco posterior vaginal para facilitar la extracción del hilo de la bolsa. Se amplió la incisión con los dedos y se extrajo el espécimen cerrándose la vagina desde el periné con visualización desde el ombligo. No se dejó drenaje abdominal. El tiempo quirúrgico fue 180 min. La paciente fue dada de alta al día siguiente sin necesidad alguna de analgesia. Un año después se encuentra libre de enfermedad y sin complicaciones. Conclusiones: La nefrectomía radical LESS umbilical con extracción vaginal resulta viable en casos seleccionados. Consigue seguridad oncológica, evita cicatrices y facilita la recuperación temprana. Desde un punto de vista práctico, este abordaje simplifica mucho la cirugía transluminal endoscópica por orificios naturales (NOTES) y permite alcanzar un resultado mínimamente invasivo equivalente

Introduction: Umbilical laparoendoscopic single-site (LESS) surgery represents an excellent alternative to laparoscopic or robotic multiport surgery. LESS surgery offers faster recovery, less postoperative pain and optimal cosmetic results. The reusable nature of its instruments also has significant economic advantages. Patient and method: We present a 34-year-old patient with a solid mesorenal lesion measuring 8 cm in the left kidney treated with pure LESS radical nephrectomy assisted by vaginal extraction of the specimen. The umbilical approachusing a single-site multichannel KeyPort (Richard Wolf GmbH, Knittlingen, Germany) with DuoRotate curved instruments allows for minimum crushing and fewer spatial conflicts. Its perfect umbilical adaptation provides a hermetic system. The instrument's double rotation provides considerable movement precision. Vaginal extraction avoids damage to the abdominal wall and the need for widening the umbilical incision. Results: After the placement of the device and triangulation of the clips, we proceeded to operate on posterior parietal peritoneum. The descending colon was mobilized to access the retroperitoneum and dissect the renal hilum. Hem-o-lok clips were placed on the artery and vein, which were subsequently sectioned. The specimen was inserted into a laparoscopic bag. Under direct vision, we placed a 15-mm trocar through the bottom of the vaginal posterior fornix to facilitate the extraction of the bag's thread. The incision was widened with the fingers, and the specimen was extracted, closing the vagina from the perineum with visualization from the navel. Abdominal drainage was not employed. The surgical time was 180 min. The patient was discharged the following day without needing analgesia. A year later, the patient was disease-free and had no complications. Conclusion: Umbilical LESS radical nephrectomy with vaginal extractionis feasible in selected cases. The procedure is oncologically safe, avoids scars and facilitates early recovery. From a practical point of view, this approach greatly simplifies natural orifice transluminal endoscopic surgery (NOTES) and enables a minimally invasive equivalent result
