The association of type and number of high-risk criteria with cancer-specific mortality in prostate cancer patients treated with radical prostatectomy.

Objectives: This study aimed to test the association between of type and number of D'Amico high-risk criteria (DHRCs) with cancer-specific mortality (CSM) in high-risk prostate cancer patients treated with radical prostatectomy. Materials and methods: In the Surveillance, Epidemiology, and End Results database (2004-2016), we identified 31,281 radical prostatectomy patients with at least 1 DHRC, namely, prostate-specific antigen (PSA) >20 ng/mL (hrPSA), biopsy Gleason Grade Group (hrGGG) score of 4 and 5, or clinical tumor stage ≥T3 (hrcT). Multivariable Cox regression models and competing risks regression models (adjusting for other cause mortality) tested the association between DHRCs and 5-year CSM. Results: Of 31,281 patients, 14,394 (67%) exclusively harbored hrGGG, 3189 (15%) harbored hrPSA, and 1781 (8.2%) harbored hrcT. Only 2132 patients (6.8%) harbored a combination of the 2 DHRCs, and 138 (0.6%) had all 3 DHRCs. Five-year CSM rates ranged from 0.9% to 3.0% when any individual DHRC was present (hrcT, hrPSA, and hrGGG, in that order), 1.6% to 5.9% when 2 DHRCs were present (hrPSA-hrcT, hrcT-hrGGG, and hrPSA-hrGGG, in that order), and 8.1% when all 3 DHRCs were present. Cox regression models and competing risks regression confirmed the independent predictor status of DHRCs for 5-year CSM that was observed in univariable analyses, with hazard ratios from 1.00 to 2.83 for 1 DHRC, 2.35 to 5.88 for combinations of 2 DHRCs, and 7.13 for all 3 DHRCs. Conclusions: Within individual DHRCs, hrcT and hrPSA exhibited weaker effects than hrGGG did. Moreover, a dose-response effect was identified according to the number of DHRCs. Accordingly, the type and number of DHRCs allow further risk stratification within the high-risk subgroup.

Efficacy of Three Different Injection Techniques for the Endoscopic Treatment of Vesicoureteral Reflux (VUR) in Children: A Review of 10 Years of Experience.

Aim: To review our 10 years of experience with the endoscopic treatment of vesicoureteral reflux (VUR) in children, emphasizing the long-term efficacy of the "combined STING-HIT" technique. Materials and Methods: A retrospective study was performed including all children with symptomatic VUR undergoing the cystoscopic injection of bulking agents from January 2013 to December 2022 in our pediatric tertiary referral center. Three different endoscopic techniques were adopted: the "combined STING-HIT" technique, the STING technique, and the HIT technique. Treatment success was defined as symptom remission and VUR resolution on the voiding cystourethrogram (VCUG) performed at the 3-month follow-up. Results: In the study period, 140 (F:M = 64:76) patients and 228 ureters were treated at a median patient age of 3 (2.0-6.0) years. After a single endoscopic treatment, VUR resolved in 203 (88%) ureters. The VUR resolution rate after a single endoscopic treatment was 95% (n=70/74) in case of I-II VUR, 88% (n=87/99) in case of III VUR; 83% (n=38/46) in case of IV VUR; 89% (n=8/9) in case of V VUR (p-value: 0.174). Overall, one or two endoscopic treatments succeeded in 219 (96%) ureters. The overall VUR resolution rate following one or two endoscopic treatments was 100% (74/74) in case of I-II VUR, 93% (n=92/99) in case of III VUR; 96% (n=44/46) in case of IV VUR; 100% (n=9/9) in case of V VUR (p-value: 0.083). Despite not being statistically significant, the VUR resolution rate was higher for the "combined STING-HIT" technique, both after one (92%: n=110/119; versus 85%; n=62/73 versus 86%; n=31/36; p-value: 0.225) or two (98%: n=116/119; versus 95%; n=69/73 versus 94%; n=34/36; p-value: 0.469) endoscopic treatments. Conclusion: The endoscopic approaches were highly successful for the treatment of VUR in children. The "combined STING-HIT" technique was a safe and effective procedure, being associated with the higher resolution rate.

Is it safe to implant a penile prosthesis in a solid organ transplant recipient? A systematic review.

Solid organ transplant recipients exhibit an elevated incidence of erectile dysfunction, attributed to comorbidities and specific factors associated with organ failure. While treatment mirrors the general population's, response rates are lower, and there is a heightened concern about implanting a penile prosthesis in immunocompromised patients due to the potential occurrence of severe complications. The aim of this study was to assess the safety of penile prostheses in this population. Among fourteen included studies, ten were case reports or series of cases, and four were non randomized case-control studies with non-transplanted patients as controls. Complications affected 34 patients (11.15%), with mechanical device failures in 18 cases (5.9%) and infections in 13 cases (4.26%). Most infections required hospitalization, antibiotic treatment, and prosthesis removal, with two cases of life-threatening Fournier's gangrene. Case-control studies revealed no differences in overall reoperation rates between transplant recipients and controls. However, pelvic organ transplant recipients undergoing three-piece prosthesis implantation showed higher complications rates related to reservoir issues. Despite limited evidence, case-control studies demonstrated a generally low/moderate risk of bias within each specific domain, although overall bias was moderate/severe. As a result, clinicians may mitigate concerns regarding penile prosthesis implantation in solid organ transplant recipients.

Antibiotic-sparing Strategies for Prevention of Recurrent Urinary Tract Infection.

Non-antimicrobial prophylactic options for recurrent urinary tract infections (rUTIs) can be personalized for each patient. A combination of different non-antibiotic strategies may provide the optimal strategy for reducing rUTIs. Management of rUTIs remains challenging for urologists and distressing for patients.

Video-Assisted Informed Consent in Endoscopic Urology: A Randomized Trial on Ureteroscopy.

Purpose: The aim of this study is to evaluate the possible benefits of using video consent in the preoperative ureteroscopy (URS) consent process. Material and Methods: Prospective randomized trials took place at two Italian tertiary-care centers from March 2022 to September 2022. Patients were randomly assigned to two groups: Group A (standard verbal/written informed consent) and Group B (informed consent supported by video). We investigated the impact of both types of informed consent on patient anxiety levels using the Spielberger State-Trait Anxiety Inventory (STAI) questionnaire both pre- and post-consent. In addition, using the Visual Analogue Scale, analysis of the effect of informed consent on postoperative pain and the number of calls for assistance during hospitalization as secondary outcomes was done. To assess the satisfaction level related to the whole process, patients were asked to rate their experience on a scale of 1-10, with 1 indicating "not satisfied" and 10 indicating "completely satisfied." Results: Overall, 166 patients were randomized 1:1 in each group. The multivariable regression model demonstrated that video-assisted informed consent significantly increased the difference between post- and pre-consent STAI with a reduced level of anxiety. The video-assisted informed consent significantly predicted the number of assistance calls during hospitalization. Conclusions: Video consent for ureteroscopies is a valid tool to improve procedure awareness and satisfaction. Video consent is able to reduce procedure-related patient anxiety and postoperative assistance calls, thus proving to be useful in obtaining better-informed consent for endourological procedures.

External validation of a nomogram for outcome prediction in management of medium-sized (1-2 cm) kidney stones.

BACKGROUND: Stone nomogram by Micali et al., able topredict treatment failure of shock-wave lithotripsy (SWL), retrograde intrarenal surgery (RIRS) and percutaneous nephrolithotomy (PNL) in the management of single 1-2 cm renal stones, was developed on 2605 patients and showed a high predictive accuracy, with an area under ROC curve of 0.793 at internal validation. The aim of the present study is to externally validate the model to assess whether it displayed a satisfactory predictive performance if applied to different populations. METHODS: External validation was retrospectively performed on 3025 patients who underwent an active stone treatment from December 2010 to June 2021 in 26 centers from four countries (Italy, USA, Spain, Argentina). Collected variables included: age, gender, previous renal surgery, preoperative urine culture, hydronephrosis, stone side, site, density, skin-to-stone distance. Treatment failure was the defined outcome (residual fragments >4 mm at three months CT-scan). RESULTS: Model discrimination in external validation datasets showed an area under ROC curve of 0.66 (95% 0.59-0.68) with adequate calibration. The retrospective fashion of the study and the lack of generalizability of the tool towards populations from Asia, Africa or Oceania represent limitations of the current analysis. CONCLUSIONS: According to the current findings, Micali's nomogram can be used for treatment prediction after SWL, RIRS and PNL; however, a lower discrimination performance than the one at internal validation should be acknowledged, reflecting geographical, temporal and domain limitation of external validation studies. Further prospective evaluation is required to refine and improve the nomogram findings and to validate its clinical value.

European Association of Urology Guidelines on Urological Infections: Summary of the 2024 Guidelines.

BACKGROUND AND OBJECTIVE: Urological infections significantly impact the wellbeing and quality of life of individuals owing to their widespread occurrence and diverse clinical manifestations. The objective of the guidelines panel was to provide evidence-based guidance on the diagnosis, treatment, and prevention of urinary tract infections (UTIs) and male accessory-gland infections, while addressing crucial public health aspects related to infection control and antimicrobial stewardship. METHODS: For the 2024 guidelines on urological infections, new and relevant evidence was identified, collated, and appraised via a structured assessment of the literature. Databases searched included Medline, EMBASE, and the Cochrane Libraries. Recommendations within the guidelines were developed by the panel to prioritise clinically important care decisions. The strength of each recommendation was determined according to a balance between desirable and undesirable consequences of alternative management strategies, the quality of the evidence (including the certainty of estimates), and the nature and variability of patient values and preferences. KEY FINDINGS AND LIMITATIONS: Key recommendations emphasise the importance of a thorough medical history and physical examination for patients with urological infections. The guidelines stress the role of antimicrobial stewardship to combat the rising threat of antimicrobial resistance, providing recommendations for antibiotic selection, dosing, and duration on the basis of the latest evidence. CONCLUSIONS AND CLINICAL IMPLICATIONS: This overview of the 2024 EAU guidelines offers valuable insights into managing urological infections and are designed for effective integration into clinical practice. PATIENT SUMMARY: The European Association of Urology has issued an updated guideline on urological infections. The guidelines provide recommendations for diagnosis, treatment, and prevention, with a particular focus on minimising antibiotic use because of the increasing global threat of antimicrobial resistance.

Antenatal Determinants of Postnatal Renal Function in Fetal Megacystis: A Systematic Review.

Introduction: To evaluate the clinical usefulness of demographic data, fetal imaging findings and urinary analytes were used for predicting poor postnatal renal function in children with congenital megacystis. Materials and methods: A systematic review was conducted in MEDLINE's electronic database from inception to December 2023 using various combinations of keywords such as "luto" [All Fields] OR "lower urinary tract obstruction" [All Fields] OR "urethral valves" [All Fields] OR "megacystis" [All Fields] OR "urethral atresia" [All Fields] OR "megalourethra" [All Fields] AND "prenatal ultrasound" [All Fields] OR "maternal ultrasound" [All Fields] OR "ob-stetric ultrasound" [All Fields] OR "anhydramnios" [All Fields] OR "oligohydramnios" [All Fields] OR "renal echogenicity" [All Fields] OR "biomarkers" [All Fields] OR "fetal urine" [All Fields] OR "amniotic fluid" [All Fields] OR "beta2 microglobulin" [All Fields] OR "osmolarity" [All Fields] OR "proteome" [All Fields] AND "outcomes" [All Fields] OR "prognosis" [All Fields] OR "staging" [All Fields] OR "prognostic factors" [All Fields] OR "predictors" [All Fields] OR "renal function" [All Fields] OR "kidney function" [All Fields] OR "renal failure" [All Fields]. Two reviewers independently selected the articles in which the accuracy of prenatal imaging findings and fetal urinary analytes were evaluated to predict postnatal renal function. Results: Out of the 727 articles analyzed, 20 met the selection criteria, including 1049 fetuses. Regarding fetal imaging findings, the predictive value of the amniotic fluid was investigated by 15 articles, the renal appearance by 11, bladder findings by 4, and ureteral dilatation by 2. The postnatal renal function showed a statistically significant relationship with the occurrence of oligo- or anhydramnion in four studies, with an abnormal echogenic/cystic renal cortical appearance in three studies. Single articles proved the statistical prognostic value of the amniotic fluid index, the renal parenchymal area, the apparent diffusion coefficient (ADC) measured on fetal diffusion-weighted MRI, and the lower urinary tract obstruction (LUTO) stage (based on bladder volume at referral and gestational age at the appearance of oligo- or anhydramnios). Regarding the predictive value of fetal urinary analytes, sodium and ß2-microglobulin were the two most common urinary analytes investigated (n = 10 articles), followed by calcium (n = 6), chloride (n = 5), urinary osmolarity (n = 4), and total protein (n = 3). Phosphorus, glucose, creatinine, and urea were analyzed by two articles, and ammonium, potassium, N-Acetyl-l3-D-glucosaminidase, and microalbumin were investigated by one article. The majority of the studies (n = 8) failed to prove the prognostic value of fetal urinary analytes. However, two studies showed that a favorable urinary biochemistry profile (made up of sodium < 100 mg/dL; calcium < 8 mg/dL; osmolality < 200 mOsm/L; ß2-microglobulin < 4 mg/L; total protein < 20 mg/dL) could predict good postnatal renal outcomes with statistical significance and urinary levels of ß2-microglobulin were significantly higher in fetuses that developed an impaired renal function in childhood (10.9 ± 5.0 mg/L vs. 1.3 ± 0.2 mg/L, p-value < 0.05). Conclusions: Several demographic data, fetal imaging parameters, and urinary analytes have been shown to play a role in reliably triaging fetuses with megacystis for the risk of adverse postnatal renal outcomes. We believe that this systematic review can help clinicians for counseling parents on the prognoses of their infants and identifying the selected cases eligible for antenatal intervention.

Office-based management of Non-Muscle Invasive Bladder Cancer (NMIBC): A position paper on current state of the art and future perspectives.

To the Editor, Bladder cancer is one of the most common cancers in humans, representing the 7th and 17th type of neoplasm in both genders. Its incidence and mortality are quite heterogeneous in different countries and are due to different risk factors, quality and prevalence of healthcare and the possibility of early diagnosis and treatment of the tumor and its potential recurrences [...].

Evaluation of predictive factors for i-CLARAS (intraoperative complications in laparoscopic renal and adrenal surgery): a multicentre international retrospective cohort study.

The laparoscopic approach represents the standard of treatment for renal and adrenal diseases, and its use is increasing even outside referral centres. Although most procedures are routinely performed, intraoperative complications do not occur, and the rate and predictive factors of these complications have not been established. The aim of this study was to evaluate the incidence and type of intraoperative complications and to identify predictive factors in patients undergoing laparoscopic renal and adrenal surgery. This was a cohort, multicentre, international retrospective study. Patients who underwent laparoscopic renal and adrenal surgeries between April 2017 and March 2022 were included in the study. Bivariate analysis was performed using contingency tables and the χ2 test for independent samples to compare qualitative variables and the T test and Mood test for continuous variables. Multivariate analysis was performed using a logistic regression model to obtain adjusted odds ratios. A total of 2374 patients were included in the study. Intraoperative complications were reported for 8.09% of patients who underwent renal surgery, with the most common complications reported being hollow viscus and vascular complications, and for 6.75% of patients who underwent adrenal surgery, with the most common complication reported being parenchymatous viscous complications. Multivariate analysis revealed that both adrenal and renal surgery radiological preoperative factors, such as invasive features during adrenalectomy and the RENAL score during nephrectomy, are predictive factors of intraoperative complications. In contrast to existing data, surgeon experience was not associated with a reduction in the incidence of perioperative complications.

Ultrasound imaging of male urethral stricture disease: a narrative review of the available evidence, focusing on selected prospective studies.

PURPOSE: To synthetize the current scientific knowledge on the use of ultrasound of the male urethra for evaluation of urethral stricture disease. This review aims to provide a detailed description of the technical aspects of ultrasonography, and provides some indications on clinical applications of it, based on the evidence available from the selected prospective studies. Advantages and limitations of the technique are also provided. METHODS: A comprehensive literature search was performed using the Medline and Cochrane databases on October 2022. The articles were searched using the keywords "sonourethrography", "urethral ultrasound", "urethral stricture" and "SUG". Only human studies and articles in English were included. Articles were screened by two reviewers (M.F. and K.M.). RESULTS: Our literature search reporting on the role of sonourethrography in evaluating urethral strictures resulted in selection of 17 studies, all prospective, even if of limited quality due to the small patients' number (varied from 28 to 113). Nine studies included patients with urethral stricture located in anterior urethra and eight studies included patients regardless of the stricture location. Final analysis was based on selected prospective studies, whose power was limited by the small patients' groups. CONCLUSION: Sonourethrography is a cost-effective and safe technique allowing for a dynamic and three-dimensional urethra assessment. Yet, because of its limited value in detecting posterior urethral strictures, the standard urethrography should remain the basic 'road-map' prior to surgery. It is an operator-dependent technique, which can provide detailed information on the length, location, and extent of spongiofibrosis without risks of exposure to ionizing radiation.

New minimally invasive solutions for Benign Prostatic Obstruction (BPO) management: A position paper from the UrOP (Urologi Ospedalità Gestione Privata).

To the Editor, In recent years, alternative solutions have been proposed to obtain effective results comparable to TURP, which is currently considered the gold standard, and laser vapo-enucleation techniques (1, 2), but with the possibility of maintaining sexual functions. In recent years there has been a growing trend towards ejaculation preservation. Although the results of TURP (3), and most laser enucleation techniques are undoubted in the Benign Prostatic Hyperplasia (BPH) and Lower Urinary Tract Symptoms (LUTS) management, they often lack in the preservation of ejaculation. All the alternative recently proposed interventions (Rezum, AquaBeam, Urolift, TPLA, i-TIND, LEST) are procedures considered by some authors to be promising in both managing BPO and preserving sexual functions. However, all these methods are limited by a lack of long-term follow-up that would evaluate the efficacy over time, possible complications related to the method and the correct patient selection for a specific method. The aim of this letter is to summarize the available evidence and provide clinicians with practical recommendations on the use of the brand new minimally invasive techniques for the management of BPO.

Impact of Assistant Experience on Perioperative Outcomes of Simple and Radical Laparoscopic Nephrectomy: Does It Really Matter?

Background and Objectives: While systematic reviews highlight the advantages of laparoscopic nephrectomy over traditional open surgery, the impact of an assistant's experience on surgical outcomes remains unclear. This study aims to evaluate whether the level of assistant expertise influences laparoscopic nephrectomy outcomes. Materials and Methods: Retrospective data from our institutional database were analyzed for patients who underwent laparoscopic nephrectomy between January 2018 and December 2022. Procedures were performed by a highly experienced surgeon, including postgraduate year (PGY)-3 to PGY-5 residents as assistants. Senior-level assistants had completed at least 10 procedures. Patient characteristics, surgical outcomes, and postoperative details were collected. Multivariable linear and logistic regression models were performed to test the effect of assistant experience (low vs. high) on estimated blood loss (EBL), length of stay (LOS), operative time (OT), and postoperative complications. Results: 105 patients were included, where 53% had highly experienced assistants and 47% had less experienced ones. Low assistant experience and higher BMI predicted longer operative time (OT), confirmed by multivariable regression (ß = 40.5, confidence interval [CI] 18.7-62.3, p < 0.001). Assistant experience did not significantly affect EBL or LOS after adjusting for covariates (ß = -14.2, CI -91.8-63.3, p = 0.7 and ß = -0.83, CI -2.7-1.02, p = 0.4, respectively). There was no correlation between assistant experience and postoperative complications. Conclusions: Assistant experience does not significantly impact complications, EBL, and LOS in laparoscopic nephrectomy. Surgeries with less experienced assistants had longer OT, but the overall clinical impact seems limited. Trainee involvement remains safe, guided by experienced surgeons.

Urethral management after artificial urinary sphincter explantation due to cuff erosion.

Introduction: The artificial urethral sphincter (AUS) is the gold standard treatment in cases of moderate-to-severe stress urinary incontinence in males. Cuff erosions are one of the most important distant complications of AUS implantation. The optimal urethral management has still not been established. Material and methods: Search terms related to 'urethral stricture', 'artificial urinary sphincter', and 'cuff erosion' were used in the PubMed database to identify relevant articles. Results: In this mini review we identified 6 original articles that assessed the urethral management after AUS explantation due to cuff erosion and included urinary diversion by transurethral and/or suprapubic catheterization, urethrorrhaphy, and in situ urethroplasty. We summarized the results of different management methods and their efficacy in terms of preventing urethral stricture formation. We highlight the need for better-quality evidence on this topic. Conclusions: The available data do not provide a clear answer to the question of optimal urethral management during AUS explantation. There is a great need to provide higher-quality evidence on this topic.

Implementación de la teleconsulta en la práctica urológica durante la era Covid-19: ¿qué hemos aprendido? / Implementation of Remote Clinics in urology practice during the COVID-19 era: What have we learned?

La actual pandemia por COVID-19 ha requeridola implementación de medidas drásticas para frenar su avance. Las instalaciones y recursos sanitarios se están destinando de forma total o parcial para la atención de pacientes críticos. Los urólogos, nos hemos encontrado durante las semanas pasadas con cambios importantes que dificultan nuestra práctica clínica diaria. Las actividades ambulatorias como consultas externas y procedimientos ambulatorios, así como las intervenciones quirúrgicas, han tenido que ser suspendidas o retrasadas. Mientras dure esta situación, la actividad médica telemática puede proveer un soporte adecuado utilizando herramientas tecnológicas y tratando de simular las consultas médicas con vídeo llamadas o llamadas por teléfono. Pero muchos servicios y departamentos médico-quirúrgicos no se encuentran listos para implementar una práctica de consultas telemáticas a gran escala porque su experiencia es escasa. Los beneficios de la telemedicina en urología son permitir el seguimiento de pacientes, dar recomendaciones, prescribir medicamentos, y realizar un triaje de qué pacientes precisan una atención presencial en urgencias. Los programas de formación de residentes de urología también han sufrido una interrupción importante de sus actividades cotidianas, ya que se han suspendido consultas, cirugías y actividad académica. En esta situación, el uso de recursos virtuales y el "aprendizaje inteligente" se están utilizando para mantener la docencia. El objetivo de este artículo es proporcionar una revisión de la más reciente literatura acerca del uso de telemedicina en la práctica urológica moderna, con nuestras recomendaciones y conclusiones

The COVID-19 pandemic has required drastic measures for an attempt in controlling its spread. Health resources and facilities are being destined for the treatment of critically ill infected patients. During the past weeks, we, as urologists have faced increasingly difficult changes in practice, as outpatient activity and elective surgeries must be postponed in order to save resources and limit the mobilization of patients and faculty. During this conflictive situation, telehealth medicine can provide adequate support using technological tools and trying to simulate face-to-face consults with the use of video or telephone calls. However, many outpatient clinics and facilities are not ready yet for telehealth as their experience in this area is low. The benefits for telemedicine in urology are continuing urologic outpatient follow-up, providing recommendations and prescriptions, and the triage of patients who will need urgent procedures. Urology residency training has suffered an abrupt disruption nowadays as outpatient, surgical and academic meetings are cancelled. In this scenario, virtual strategies and "smart learning" activities are being used to continue education. We provide a review of the latest published literature regarding the use of telehealth medicine or telemedicine for the modern urology practice, alongside our recommendations and conclusions

Dermal graft surgery for peyronie’s disease: long term results at a 15 years follow-up / Cirugía con injerto dérmico en la enfermedad de Peyronie: resultados a largo plazo a los 15 años de seguimiento

Objectives: To evaluate long-term outcomes of patients subjected to corporoplasty, plaque incision and excision, and autologous dermal grafting, with at least 15 years of follow-up. Metethos: The charts of consecutive patients with a penile curvature and a minimum of 15 years follow up were retrospectively reviewed. The patients underwent corporoplasty and penile straightening with autologous dermal grafting, harvested at the level of the anterior-superior iliac spine. At the time of the follow-up, a postoperative IIEF - 5 questionnaire was administered by telephonic interview, and patients were also asked to complete an 8 items self-evaluation questionnaire. After signing informed consent, the patients were invited to undergo dynamic and basal penile sonography, as well as injection of 10 mcg of PGE1 for dynamic evaluation of the graft. Results: A total of 16 patients were identified. Penile shortening of up to 1.5 cm was reported in about 40% of cases and residual bending was reported by 4 of 16 patients. However, there was no impairment in penetration. On physical examination of the suture site, a small indurated nodule was palpable in two patients. Data regarding the dynamic sonography is available for the 5 patients who accepted to undergo the test. No sign of a fibrotic reaction or calcification was detected in the static phase. After injection of 10 mcg PGE-1, in comparison to the basal measurement, the dermal grafts showed compliant length adaptation. Conclusions: Dermal graft substitution surgery for Peyronie's disease allows to obtain good functional results with durable satisfaction of the patients on long term follow up

Objetivos: Evaluar los resultados a largo plazo de los pacientes sometidos a corporoplastia, incisión y escisión de la placa, e injerto dérmico autólogo, con al menos 15 años de seguimiento. Métodos: Revisamos retrospectivamente las historias clínicas de los pacientes con incurvación peneana y un mínimo de 15 años de seguimiento. Los pacientes fueron sometidos consecutivamente a corporoplastia y corrección de la curvatura con injerto dérmico autólogo, obtenido a nivel de la espina iliaca antero-superior. En el seguimiento, se pasó el cuestionario IIEF-5 postoperatorio mediante entrevista telefónica, y también se pidió a los pacientes completar un cuestionario de autoevaluación de 8 preguntas. Después de firmar un consentimiento informado, los pacientes fueron invitados a realizar ecografía peneana dinámica y basal, así como inyección de 10 mcg de PGE1, para la evaluación dinámica del injerto. Resultados: Fueron identificados un total de 16 pacientes. Cerca del 40% de los casos comunicaban un acortamiento del pene de hasta 1,5 cm y 4 de 16 pacientes referían incurvación residual. Sin embargo, no había empeoramiento de la penetración. En la exploración física del sitio de la sutura, en dos pacientes era palpable un pequeño nódulo indurado. Los datos referentes a la ecografía estaban disponibles en los 5 pacientes que aceptaron realizar la prueba. En la fase estática no se detectaron signos de reacción fibrótica o calcificación. Después de la Inyeccion de 10 mcg de PGE-1, los injertos dérmicos mostraron una adaptación longitudinal adecuada en comparación con la medición basal. Conclusiones: En la enfermedad de La Peyronie, la cirugía de substitución con injerto dérmico permite obtener buenos resultados funcionales con satisfacción de los pacientes perdurable en el seguimiento a largo plazo

Urinary bladder xanthoma: two case reports and a review of the literature / Xantoma vesical: Presentación de dos casos y revisión bibliográfica

OBJECTIVE: We present two rare cases of bladder xanthomata associated with transitional cell carcinoma. Method and results: Cases description and selection of related pictures. Review of the existing literature. CONCLUSIONS: Xanthomata are non-neoplastic lesions consisting of group of foamy lipidstoring histiocytes in the dermis of skin or in the lamina propria of mucosa. Urinary bladder is an uncommon localization for these lesions and their etiology isn't still well understood, being variably associated with abnormalities of lipid metabolism. Although sometimes they are described in association with urothelial neoplasms, they were not believed to have any biological neoplastic potential and so they are treated consequently

OBJETIVO: Presentamos dos raros casos de Xantoma vesical asociado con carcinoma de células transicionales. MÉTODOS Y RESULTADOS: Descripción de los casos y selección de imágenes relacionadas. Revisión de la bibliografía existente. CONCLUSIONES: Los xantomas son lesiones no neoplásicas constituidas por grupos de histiocitos espumosos almacenadores de lípidos en la dermis cutánea o en la lámina propia de la mucosa. La vejiga urinaria es una localización rara de estas lesiones y su etiología no se entiende bien todavía, asociándose variablemente con anomalías del metabolismo lipídico. Aunque a veces se describen en asociación con neoplasias uroteliales, no se piensa que tengan ningún potencial neoplásico y consecuentemente así se tratan
