mpMRI-US Fusion-Guided Targeted Cryotherapy in Patients with Primary Localized Prostate Cancer: A Prospective Analysis of Oncological and Functional Outcomes.

Targeted therapy (TT) for prostate cancer (PCa) aims to ablate the malignant lesion with an adequate margin of safety in order to obtain similar oncological outcomes, but with less toxicity than radical treatments. The main aim of this study was to evaluate the recurrence rate (RR) in patients with primary localized PCa undergoing mpMRI/US fusion targeted cryotherapy (FTC). A secondary objective was to evaluate prostate-specific antigen (PSA) as a predictor of recurrences. We designed a prospective single-center single-cohort study. Patients with primary localized PCa, mono or multifocal lesions, PSA ≤ 15 ng/mL, and a Gleason score (GS) ≤ 4 + 3 undergoing FTC were enrolled. RR was chosen as the primary outcome. Recurrence was defined as the presence of clinically significant prostate cancer in the treated areas. PSA values measured at different times were tested as predictors of recurrence. Continuous variables were assessed with the Bayesian t-test and categorical assessments with the chix-squared test. Univariate and logistic regression assessment were used for predictions. A total of 75 cases were included in the study. Ten subjects developed a recurrence (RR: 15.2%), while fifty-six (84.8%) patients showed a recurrence-free status. A %PSA drop of 31.5% during the first 12 months after treatment predicted a recurrence with a sensitivity of 53.8% and a specificity of 79.2%. A PSA drop of 55.3% 12 months after treatment predicted a recurrence with a sensitivity of 91.7% and a specificity of 51.9%. FTC for primary localized PCa seems to be associated with a low but not negligible percentage of recurrences. Serum PSA levels may have a role indicating RR.

Infección por SARS-CoV-2: implicaciones para la salud sexual y reproductiva. Una declaración de posición de la Asociación Española de Andrología, Medicina Sexual y Reproductiva (ASESA) / SARS-CoV-2 infection: implications for sexual and reproductive health. A position statement of the Asociación Española de Andrología, Medicina Sexual y Reproductiva (ASESA)

OBJETIVO: El objetivo de esta revisión es resumir la evidencia disponible sobre los posibles efectos adversos del SARS-CoV-2 en el sistema reproductor masculino y proporcionar una declaración de posición oficial de la Asociación Española de Andrología, Medicina Sexual y Reproductiva (ASESA). MÉTODOS: Se realizó una búsqueda exhaustiva en las bibliotecas Pubmed, Web of Science, Embase, Medline, Cochrane y MedRxiv. RESULTADOS: No se ha confirmado la orquitis como una posible complicación de la infección por SARS-CoV-2. Un estudio informó que el 19% de los hombres con COVID-19 presentaban molestias escrotales sugestivas de orquitis viral, que no se pudo confirmar. Es posible que el virus no infecte los testículos directamente, si no que desencadene una respuesta autoinmune secundaria y que cause una orquitis autoinmune. COVID-19 se ha asociado con anormalidades en la coagulación por lo que la orquitis podría ser el resultado de una vasculitis segmentaria. Los datos disponibles sobre la presencia del virus en semen son contradictorios. Sólo un estudio informó de la presencia de ARN en el 15,8% de enfermos de COVID-19. La presencia de ácido nucleico o antígeno en el semen no implica la existencia de virus con capacidad de replicación o infección. En hombres con COVID-19 se ha observado un incremento significativo de LH en suero y una drástica disminución de la ratio T/LH y FSH/LH, congruente con un hipogonadismo subclínico. CONCLUSIONES: Los datos disponibles y los hallazgos de los estudios recientes se basan en tamaños de muestra pequeños y proporcionan informaciones contradictorias. Existe la posibilidad teórica de que pueda producirse daño testicular y posterior infertilidad después de la infección por COVID-19, por lo que especialmente para aquellos hombres en edad reproductiva, se debe sugerir consulta y evaluación de la función gonadal y análisis de semen. En cuanto a la posibilidad de transmisión sexual, no hay evidencia suficiente para respaldar la necesidad de que las parejas asintomáticas eviten las relaciones sexuales para protegerse contra la transmisión del virus. Se necesita más investigación para comprender los impactos a largo plazo del SARS-CoV-2 en la función reproductiva masculina, incluidos sus posibles efectos sobre la fertilidad y la función endocrina testicular

OBJECTIVE: The main objective of this revision is to summarize the current existing evidence of the potential adverse effects of SARS-CoV-2 on the male reproductive system and provide the recommendations of the Asociación Española de Andrología, Medicina Sexual y Reproductiva (ASESA) concerning the implications of COVID-19 infection in the management of male infertilty patients and testicular endocrine dysfunction. METHODS: A comprehensive systematic literature search of the databases of PubMed, Web of Science, Embase, Medline, Cochrane and MedRxiv, was carried out. RESULTS: The presence of orchitis as a potential complication of the infection by SARS-CoV-2 has not yet been confirmed. One study reported that 19% of males with COVID-19 infection had scrotal symptoms suggestive of viral orchitis which could not be confirmed. It is possible that the virus, rather than infecting the testes directly, may induce a secondary autoimmune response leading to autoimmune orchitis. COVID-19 has been associated with coagulation disorders and thus the orchitis could be the result of segmental vasculitis. Existing data concerning the presence of the virus in semen are contradictory. Only one study reported the presence of RNA in 15.8% of patients with COVID-19. However, the presence of nucleic acid or antigen in semen is not synonyms of viral replication capacity and infectivity. It has been reported an increase in serum levels of LH in males with COVID-19 and a significant reduction in the T/LH and FSH/LH ratios, consistent with subclinical hypogonadism. CONCLUSIONS: The findings of recent reports related to the potential effects of COVID-19 infection on the male reproductive system are based on poorly designed, small sample size studies that provide inconclusive, contradictory results. Since there still exists a theoretical possibility of testicular damage and male infertilty as a result of the infection by COVID-19, males of reproductive age should be evaluated for gonadal function and semen analysis. With regard to the sexual transmission of the virus, there is not sufficient evidence to recommend asymptomatic couples to abstein from having sex in order to protect themselves from being infected by the virus. Additional studies are needed to understand the long-term effects of SARS-CoV-2 on male reproductive function, including male fertility potential and endocrine testicular function

Beyond the Limits: How to Avoid a Surgical Nightmare in the Third and Subsequent Renal Transplantation Procedures.

PURPOSE OF REVIEW: Approximately, 25% of the patients with ESRD will enter the waiting list for kidney transplantation. Among these patients, almost 15% will require a retransplantation surgery. This review aims to summarize the most recent information on different controversial issues regarding retransplantation, to provide the reader with a clear and updated view on the topic. RECENT FINDINGS: Despite current evidence is mainly based on retrospective, small, single-center experiences, it seems clear that retransplantation remains a surgical and immunological challenge, for which the perioperative management still remains crucial to avoid mishaps. Different surgical approaches have been tested, but the general consensus advocates for the heterotopic extraperitoneal in first instance. Although higher immunological risk and complication rates are reported invariably in the available series, the benefits in terms of overall survival are superior to those obtained under dialysis, thus still representing the most recommended option for this group of patients.

[Prostate cryotherapy: General principles.] / Crioterapia prostática: fundamentos y principios generales.

INTRODUCTION: Prostate cryotherapy has been consolidated as an alternative minimally invasive treatment. OBJECTIVE: To exposed its historical development, its action mechanism and the surgical technique. Regarding its indications, we expose the different option of treatment- primary cryotherapy, salvage and focal- emphasizing its oncological results in the absence of randomized studies. RESULTS: Cryotherapy is a safe technique with low complication rate, although incidence of erectile dysfunction is 40-90% in case of full-gland cryotherapy. Nowadays, it is recommended as a therapeutic alternative for low and intermediate risk localized prostate cancer, although in clinical trials. Recurrence-free survival is close to 96% in low-risk tumors and 90% in intermediate-risk tumors. On the other hand, it is a salvage treatment option for local recurrence after radiotherapy. Focal therapies including focal cryoablation have an important development, with recurrence-free survival of 75%. CONCLUSION: Waiting for randomized studies that provide more scientific evidence, available retrospective studies show cryotherapy as a safe and effective treatment option in patients with localized prostate cancer.

OBJETIVO: Exponer el desarrollo histórico de la crioterapia, su mecanismo de acción sobre el tejido prostático así como la técnica quirúrgica. Se discuten los distintos escenarios ­ crioterapia primaria, de rescate y focalhaciendo énfasis en sus resultados oncológicos a falta de estudios randomizados. RESULTADOS: La crioterapia es una técnica segura con un bajo índice de complicaciones, aunque destaca una incidencia de disfunción eréctil del 40-90% en el caso de crioterapia de glándula completa. En la actualidad se recomienda como alternativa terapéutica en el cáncer de próstata localizado de riesgo bajo e intermedio, aunque dentro de ensayos clínicos. La supervivencia libre de recidiva bioquímica es cercana al 96% en tumores de bajo riesgo y al 90% en tumores de riesgo intermedio. Por otro lado, es una opción de tratamiento de rescate en el caso de recidiva local tras radioterapia siempre que se cumplan una serie de criterios (Gleason ≤7 y PSA10ng/ml). La mejora en las técnicas de imagen está permitiendo el desarrollo de terapias focales incluyendo la crioablación focal, con supervivencia libre de recidiva bioquímica del 75%. CONCLUSIONES: A la espera de estudios randomizados que aporten mayor evidencia científica, los estudios retrospectivos disponibles muestran la crioterapia como una opción de tratamiento segura y eficaz en pacientes con cáncer de próstata localizado.

Surgical Management of Peyronie's Disease With Co-Existent Erectile Dysfunction.

INTRODUCTION: Surgical intervention in Peyronie's disease (PD) should ideally be delayed until the resolution of acute inflammatory phase. AIM: The objective of this review was to highlight the results of penile prosthesis to correct refractory erectile dysfunction (ED) in patients with PD, and the secondary procedures that may be required to correct the penile curvature. METHODS: A systematic search on PubMed online database using Preferred Reporting Items for Systematic Reviews and Meta-Analyses recommendations was done using the MeSH terms "Peyronie's disease" and "erectile dysfunction." MAIN OUTCOME MEASURE: Success and satisfaction rates of various procedures. RESULTS: The search yielded 324 language-specific (English and Spanish language) articles and 58 articles were retained for final review. The following variables were assessed in different studies: number of patients, types of secondary procedure to correct the curvature, satisfaction rates, and follow-up period. CONCLUSION: The aim of the surgery in PD should be to achieve a functionally straight penis (<20 degree curvature) with good erection. Patients with refractory ED in PD are candidates for penile prosthesis. Secondary procedures, like manual modeling, plication, plaque incision, or excision grafting, may be required depending on the degree of penile curvature and penile length. In quest for the best graft, TachoSil graft seems to have gained popularity in Europe. Krishnappa P, Fernandez-Pascual E, Carballido J, et al.

[Prognostic factors of mortality in patients with urothelial bladder tumor treated with radical cistectomy.] / Factores pronósticos de mortalidad en pacientes con tumor urotelial de vejiga tratados con cistectomía radical.

INTRODUCTION: Radical cystectomy (RC) with pelvic lymphadenectomy is the treatment of choice in patients with muscle invasive bladder cancer (MIBC). OBJECTIVE: To identify clinical and pathological variables that influence global mortality (GM) and cancer specific mortality (CSM) in patients with urothelial bladder tumor (UBT) treated with RC. METHODS: Retrospective analysis of 517 patients diagnosed with UBT and treated with RC between 1986 and 2009. Demographic, clinical, surgical and pathological variables, as well as complications and evolution after RC were collected. A comparative analysis was carried out with Chi square and ANOVA test. Survival analysis was performed with the Kaplan-Meier method and the long-rank test. Univariate and multivariate analysis were performed using Cox regression to identify independent predictors of GM and CSM. RESULTS: 91% of the patients were males with a median age of 66 years. The most frequent local pathological stage was pT3 (32.6%), with lymph node involvement in 23.8% of the patients. After a median follow-up of 34 months, 170 patients were alive and 311 had died from any cause (63.5%), being UBT the cause of death in 225 patients (45%). Rates of global survival and cancer specific survival at 5 and 10 years were 45%/34.3% and 52.5%/46.6% respectively. On the multivariate analysis age ( p = 0.004), ASA ( p = 0.000), the existence of hydronephrosis ( p = 0.01), pT ( p = 0.000) and pN ( p = 0.003) were identified as independent predictors of GM, as well as pT ( p = 0.000) and pN ( p = 0.002) for CSM. CONCLUSIONS: Age, anesthetic risk, presence of hydronephrosis, pT and pN stage were identified as independent predictors of GM, as well as pT and pN stage for CSM.

Vascular Injury During Urologic Surgery: Somebody Call My Mother.

PURPOSE OF REVIEW: To provide the critical elements to effectively manage hemorrhage from vascular injuries sustained during planned urological interventions. RECENT FINDINGS: The frequency of intraoperative vascular injuries is increasing. However, literature concerning the management of iatrogenic operative vascular injuries is scarce. Although rare, intraoperative vascular injuries may be associated with potential catastrophic complications and death. The decision-making process following a potential life-threatening intraoperative vascular injury occurs in a very short time frame. Appropriate knowledge of the critical elements to identify the source of bleeding, initiate first-line hemostatic measures, select the candidate for damage control strategies, and perform the indicated operative repairing maneuvers and techniques have been proved crucial to ensure hemodynamic stability and bleeding cessation. The key surgical principles to counteract the impact of exsanguinating bleeding, and the aim to obtain the best achievable outcomes after definitive repair, are described in detail in this review.

[Right spermatic vein thrombosis. Revision of literature regarding a specific case]. / Trombosis de la vena espermática derecha. Revisión de la literatura a propósito de un caso.

Acute thrombophlebitis of spermatic vein is an unusual pathology involving, in most of the cases, the left side, and whose etiology remains uncertain. Most of them are found during a a differential diagnosis in acute testicular pain. We introduce the case of a 29 years old male with abusive cocaine consumption, admitted to hospital due to severe testicular pain. Doppler-ultrasound examination was undertaken, showing right spermatic vein flux alteration. Conservative management was decided and anticoagulant and non-esteroidal anti-inflammatory drugs were started. Eco-doppler is the most specific and sensible technique for diagnosis of these cases, while TC can always confirm etiologic diagnosis. Treatment was initially conservative based on anticoagulation. Hematological study is necessary in order to determine coagulation alterations.

European Association of Urology Guidelines on Renal Transplantation: Update 2018.

CONTEXT: The European Association of Urology (EAU) panel on renal transplantation (RT) has released an updated version of the RT guidelines. OBJECTIVE: To present the 2018 EAU guidelines on RT. EVIDENCE ACQUISITION: A broad and comprehensive scoping exercise was performed, encompassing all areas of RT guidelines published between January 1, 2007, and May 31, 2016. Databases covered by the search included Medline, Embase, and the Cochrane Libraries. Previous guidelines were updated, and levels of evidence and grades of recommendation were assigned. EVIDENCE SYNTHESIS: It is strongly recommended to offer pure or hand-assisted laparoscopic/retroperitoneoscopic surgery as the preferential technique for living donor nephrectomy. Decisions on the acceptance of a donor organ should not be based on histological findings alone since this might lead to an unnecessarily high rate of discarded grafts. For ureterovesical anastomosis, a Lich-Gregoir-like extravesical technique protected by a ureteral stent is the preferred technique for minimisation of urinary tract complications. It is also strongly recommended to perform initial rejection prophylaxis with a combination therapy comprising a calcineurin inhibitor (preferably tacrolimus), mycophenolate, steroids, and an induction agent (either basiliximab or anti-thymocyte globulin). The long version of the guidelines is available at the EAU website (http://uroweb.org/guidelines). CONCLUSIONS: These abridged EAU guidelines present updated information on the clinical and surgical management of RT for incorporation into clinical practice. PATIENT SUMMARY: The European Association of Urology has released the renal transplantation guidelines. The implementation of minimally invasive surgery for organ retrieval and the latest evidence on transplant surgery as well as on immunosuppressive regimens are key factors for minimisation of rejection and achievement of long-term graft survival.

Trombosis de la vena espermática derecha. Revisión de la literatura a propósito de un caso / Right spermatic vein thrombosis. Revision of literature regarding a specific case

La tromboflebitis aguda de la vena espermática es una dolencia de muy baja frecuencia, con afectación mayoritaria del lado izquierdo, y de etiología desconocida en la mayoría de las ocasiones. Suele ser un hallazgo inesperado en el diagnóstico diferencial del dolor testicular agudo. Se trata de un varón de 29 años con un consumo abusivo de cocaína que acude con dolor testicular agudo. Se confirma la afectación de la vena espermática derecha mediante ecografía-doppler. Se optó por manejo conservador con anticoagulación y antiinflamatorios. La eco-doppler es la técnica con mayor especificidad y sensibilidad para diagnosticarlo, mientras que la TC puede completar su diagnóstico etiológico. El tratamiento de elección es conservador basado en la anticoagulación del paciente. Es imperativo un estudio hematológico en búsqueda de alteraciones de la coagulación (AU)

The Risk of Tumour Recurrence in Patients Undergoing Renal Transplantation for End-stage Renal Disease after Previous Treatment for a Urological Cancer: A Systematic Review.

CONTEXT: Renal transplantation is the gold standard renal replacement therapy in end-stage renal disease owing to its superior survival and quality of life compared with dialysis. When the potential recipient has a history of cancer, the waiting period before renal transplantation is usually based on the Cincinnati Registry. OBJECTIVE: To systematically review all available evidence on the risk of cancer recurrence in end-stage renal disease patients with a history of urological cancer. EVIDENCE ACQUISITION: Medline, Embase, and the Cochrane Library were searched up to March 2017 for all relevant publications reporting oncologic outcomes of urological cancer in patients who subsequently received a transplantation or remained on dialysis. The primary outcome was time to tumour recurrence. Secondary outcomes included cancer-specific and overall survival. Data were narratively synthesised in light of methodological and clinical heterogeneity. The risk of bias of each included study was assessed. EVIDENCE SYNTHESIS: Thirty-two retrospective studies enrolling 2519 patients (1733 dialysed, 786 renal transplantation) were included. For renal cell carcinomas, the risks of recurrence, cancer-specific, and overall survival were similar between transplantation and dialysis. For prostate cancer, most of the tumours had favourable prognoses consistent with nomograms. Studies dealing with urothelial carcinomas (UCs) mainly included upper urinary tract UC in the context of aristolochic acid nephropathy, for which the risks of synchronous bilateral tumour and recurrence were high. Data on testicular cancer were scarce. CONCLUSIONS: Immunosuppression after renal transplantation does not affect the outcomes and natural history of low-risk renal cell carcinomas and prostate cancer. Therefore, the waiting time from successful treatment for these cancers to transplantation could be reduced. Except in the particular situation of aristolochic acid nephropathy, more studies are needed to standardise the waiting period after UC owing to the paucity of data. PATIENT SUMMARY: Renal transplantation does not appear to increase the risk of recurrence of renal carcinoma or the recurrence of low-risk prostate cancer compared with dialysis. More reliable evidence is required to recommend a standard waiting period especially for urothelial and testicular carcinomas.

Beneficial Effect of Short Pretransplant Period of Hypothermic Pulsatile Perfusion of the Warm-Ischemic Kidney after Cold Storage: Experimental Study.

Warm ischemia (WI) produces a significant deleterious effect in potential kidney grafts. Hypothermic machine perfusion (HMP) seems to improve immediate graft function after transplant. Our aim was to analyze the effect of short pretransplant periods of pulsatile HMP on histology and renal injury in warm-ischemic kidneys. Twelve minipigs were used. WI was achieved in the right kidney by applying a vascular clamp for 45 min. After nephrectomy, autotransplant was performed following one of two strategies: cold storage of the kidneys or cold storage combined with perfusion in pulsatile HMP. The graft was removed early to study renal morphology, inflammation (fibrosis), and apoptosis. Proinflammatory activity and fibrosis were less pronounced after cold storage of the kidneys with HMP than after cold storage only. The use of HMP also decreased apoptosis compared with cold storage only. The detrimental effects on cells of an initial and prolonged period of WI seem to improve with a preservation protocol that includes a short period of pulsatile HMP after cold storage and immediately before the transplant, in comparison with cold storage only.

Rectourethral Fistula Management.

Rectourethral fistula (RUF) is a rare condition that occurs, in most cases, as a consequence of prostate cancer treatments. Clinical suspicion and proper assessment prior to surgery are essential to adapt and successfully carry out an appropriate treatment plan. There are no randomized trials to guide clinical practice, and therefore, scientific evidence in this respect is limited. Expert recommendations seem to agree on the transperineal approach with flap interposition as the surgical treatment of choice in cases of complex fistulas, especially in those that have undergone prior radiation. Undoubtedly, the key to the successful treatment of the disease is the multidisciplinary and standardized management by physicians with experience in the field.

Penile Prosthesis First and Replacement Surgeries: Analysis of Patient and Partner Satisfaction.

INTRODUCTION: Among the many treatments for erectile dysfunction, implantation of a penile prosthesis has been associated with high patient satisfaction rates. Prosthesis replacement has become an accepted procedure in the event of device malfunction or complications, but to our knowledge, there are no data regarding the impact of implant replacement on patients and partner satisfaction. AIM: The aim of our study was to assess and to compare the level of satisfaction, with a first or second penile prosthesis implantation (PPI), in men with refractory erectile dysfunction and their partners. METHODS: A survey study based on a five-item questionnaire was carried out at our center between January 1999 and January 2012. MAIN OUTCOME MEASURES: The main outcome measure used was the level of patient and partner satisfaction with sexual intercourse after PPI. RESULTS: Of the 190 eligible patients, 149 (78%) completed the survey (110 underwent a first implant and 39 a reimplant). Seventy-nine percent of first-time implanted patients and 80% of the reimplanted patients (P > 0.05; not significant [ns]) reported satisfactory sexual intercourse (very or moderately satisfied), while 74% and 80% of their partners reported satisfactory intercourses, respectively (P > 0.05; ns). Overall, 73.7% of first implants and 70% of second implants reported that they would undergo the procedure again if the PPI failed (P > 0.05; ns). With regards to cosmetic aspects, 13% of the first implants' and 15% of second implants' partners reported either penile shortness or soft glans as the main causes of their dissatisfaction. Only 2.4% of first implants and 1% of reimplanted patients expressed difficulty in manipulating the device. CONCLUSIONS: PPI is successful in returning the ability for satisfactory sexual intercourse to both first implant and reimplanted patients and their respective partners.

Effects of tadalafil once daily or on demand versus placebo on time to recovery of erectile function in patients after bilateral nerve-sparing radical prostatectomy.

PURPOSE: We report time to erectile function (EF)-recovery data from a multicenter, randomized, double-blind, double-dummy, placebo-controlled trial evaluating tadalafil started after bilateral nerve-sparing radical prostatectomy (nsRP). METHODS: Patients ≤68 years were randomized post-nsRP 1:1:1 to 9-month double-blind treatment (DBT) with tadalafil 5 mg once daily (OaD), 20 mg tadalafil on demand ("pro-re-nata"; PRN), or placebo, followed by 6-week drug-free washout (DFW) and 3-month open-label OaD treatment. Secondary outcome measures included Kaplan-Meier estimates of time to EF-recovery (IIEF-EF ≥ 22) during DBT (Cox proportional hazard model adjusting for treatment, age, and country). RESULTS: A total of 423 patients were randomized to tadalafil OaD (N = 139), PRN (N = 143), and placebo (N = 141); 114/122/155 completed DBT. The proportion of patients achieving IIEF-EF ≥22 at some point during DBT with OaD, PRN, and placebo was 29.5, 23.9, and 18.4 %, respectively. DBT was too short to achieve EF-recovery (IIEF-EF ≥ 22) in >50 % of patients; median time to EF-recovery was non-estimable. Time for 25 % of patients to achieve EF-recovery (95 % CI) was 5.8 (4.9, 9.2) months for OaD versus 9.0 (5.5, 9.2) and 9.3 (9.0, 9.9) months for PRN and placebo, respectively. Showing a significant overall treatment effect (p = 0.038), the probability for EF-recovery was significantly higher for OaD versus placebo [hazard ratio (HR); 95 % CI 1.9; 1.2, 3.1; p = 0.011], but not for PRN versus placebo (p = 0.140). Of 57 OaD patients (41.0 %) with ED improved (by ≥1 IIEF-EF severity grade) at the end of DBT, 16 (28.1 % of 57) maintained this improvement through DFW and 27 (47.4 %) declined but maintained improvement from baseline after DFW. CONCLUSIONS: Data suggest that the use of tadalafil OaD can significantly shorten the time to EF-recovery post-nsRP compared with placebo.

[Recto-urethral fistula secondary to prostate cancer]. / Fístulas recto-uretrales secundarias a tratamiento de cáncer de próstata.

OBJECTIVES: There are various treatments forprostate cancer nowadays, including techniques that have been used for manyyears such as surgery and radiotherapy, and newer procedures that are gaining prominence in the Urological field like cryotherapy or HIFU (high intensity focused ultrasound). Rectourethral fistula is a rare complication that demands the urologist a great capacity; it may happen after either existent treatment. METHODS: PubMed literature review with articles published during the last 10 years using the terms "rectourethral fistula" and "prostate cancer". EVIDENCE SINTHESIS: We present the current situation of rectourethral fistula secondary to prostate cancer in terms of epidemiology, diagnosis and treatment, with special focus on the various types of fistulae and their management. We comment on general features in relation to surgical management of this pathology; type of approach, type of repair, use of flaps, concomitant fistula and urethralstenosis, delay of surgery and bowel diversion. We describe the surgical techniques more frequently used today and their limitations. We present the results published by different groups with each of these techniques, as well as the corresponding recommendations based on each group's experience. CONCLUSIONS: Rectourethral fistula is a surgical challenge for the urologist. We must choose the appropriate management in accordance to the characteristics of the fistula.

Fístulas recto-uretrales secundarias a tratamiento de cáncer de próstata / Recto-urethral fistula secondary to prostate cancer

OBJETIVO: Actualmente existen diversos tratamientos para el cáncer de próstata que incluyen técnicas utilizadas desde hace muchos años, como la cirugía y la radioterapia, y procedimientos más novedosos que van tomando protagonismo en la Urología como la crioterapia o los ultrasonidos focalizados de alta intensidad (HIFU). La fístula rectouretral es una complicación poco frecuente que exige gran capacidad al urólogo y que puede acontecer tras cualquiera de los tratamientos existentes. ADQUISICIÓN DE EVIDENCIA: Revisión de la literatura existente en PubMed; artículos publicados en los últimos 10 años introduciendo como palabras clave: «rectourethral fistula» y «prostate cancer». SÍNTESIS DE EVIDENCIA: Presentamos la situación actual en cuanto a epidemiología, diagnóstico y tratamiento de la fístula rectouretral secundaria a tratamiento de cáncer de próstata poniendo especial interés en los distintos tipos de fístula y el manejo que debe hacerse en cada uno de ellos. Comentamos los aspectos generales relacionados con el manejo quirúrgico de esta patología: tipo de abordaje; tipo de reparación; utilización de colgajos; fístula y estenosis de uretra concomitante; demora de la cirugía y derivación digestiva. Describimos las técnicas quirúrgicas más utilizadas en la actualidad y sus limitaciones. Presentamos los resultados publicados por distintos grupos con cada una de estas técnicas así como las recomendaciones correspondientes basadas en la experiencia de cada grupo. CONCLUSIÓN: La fístula rectouretral supone un reto quirúrgico para el urólogo. Éste debe elegir el manejo apropiado en función de las características de la fístula
