Purpose: Iatrogenic recto-urinary fistulas are a disastrous complication of therapeutic interventions on the prostate. Many surgical approaches have been described to repair recto-urinary fistulas and no consensus has been reached regarding the better approach. The objective of this study is to present the results of our updated 20-year experience in the surgical management of recto-urinary fistula using a modified York Mason procedure., Methods: We proceed to a retrospective single-institution review of surgically treated patients for iatrogenic recto-urinary fistulas between 1998 and 2017 by the modified York Mason technique. Descriptive analysis of our population was performed. Continuous and categorical variables were compared using Mann-Whitney and Fischer tests, respectively. All tests were two-sided with a significance level set at p value < 0.05., Results: We included 30 consecutive patients treated for iatrogenic recto-urinary fistula. The median follow-up was 76 months (2-195). The median size of the fistula was 5 mm (2-20). Successful healing of the recto-urinary fistula was observed in 80, 97, and 100% of patients after 1, 2, or 3 York Mason procedure. During the study period, no one single case of acquired urinary incontinence or durable fecal incontinence has been observed., Conclusions: Our modified York Mason technique is a reliable and effective procedure with a 100% success rate for the repair of small iatrogenic recto-urinary fistulas in non-irradiated patients. It has a very low morbidity rate, and no case of postoperative urine or fecal incontinence has been observed.

Background: Accurate prediction of survival after radical prostatectomy (RP) is important for making decisions regarding multimodal therapies. There is a lack of tools to predict prostate cancer-related death (PCRD) in patients with high-risk features., Objective: To develop and validate a prognostic model that predicts PCRD combining pathologic features and using competing-risks analysis., Design, Setting, and Participants: This was a retrospective multi-institutional observational cohort study of 5876 patients affected by high-risk prostate cancer. Patients were treated using RP and pelvic lymph node dissection (PLND) in a multimodal setting, with median follow-up of 49 mo., Outcome Measurements and Statistical Analysis: For PCRD prediction, a multivariate model with correction for competing risks was constructed to evaluate pathologic high-risk features (pT3b-4, Gleason score ≥8, and pN1) as predictors of mortality. All possible associations of the predictors were combined, and then subgroups with similar risk of PCRD were collapsed to obtain a simplified model encoding subgroups with significantly differing risk. Eightfold cross-validation of the model was performed., Results and Limitations: After applying exclusion criteria, 2823 subjects were identified. pT3b-4, Gleason score ≥8, and pN1 were all independent predictors of PCRD. The simplified model included the following prognostic groups: good prognosis, pN0 with 0-1 additional predictors; intermediate prognosis, pN1 with 0-1 additional predictors; poor prognosis, any pN with two additional predictors. The cross-validation yielded excellent median model accuracy of 88%. The retrospective design and the short follow-up could limit our findings., Conclusions: We developed and validated a novel and easy-to-use prognostic instrument to predict PCRD after RP+PLND. This model may allow clinicians to correctly counsel patients regarding the intensity of follow-up and to tailor adjuvant treatments., Patient Summary: Prediction of mortality after primary surgery for prostate cancer is important for subsequent treatment plans. We present an accurate postoperative model to predict cancer mortality after radical prostatectomy for high-risk prostate cancer., (Copyright © 2017 European Association of Urology.

Objective: To assess the prognostic significance of positive surgical margins (PSMs) after minimally invasive radical prostatectomy (MIRP) in interaction with other established prognosis factors., Patients and Methods: We retrospectively analysed data prospectively collected between 1998 and 2010 for 4628 consecutive patients who underwent MIRP for clinically localized prostate cancer. The impact of PSM on biochemical recurrence (BCR), defined as prostate-specific antigen (PSA) >0.2 ng/mL, was evaluated using multivariable Cox proportional hazards regression. Estimates of BCR-free survival were generated using the Kaplan-Meier method and compared among groups using the log-rank test., Results: The median follow-up was 55 months. On multivariable analysis, PSM was an independent prognostic factor for BCR (adjusted hazard ratio: 2.14 for PSMs vs negative surgical margins (NSMs); 95% confidence interval [CI]: 1.86-2.45; P < 0.001). Other independent predictors for BCR were preoperative PSA, date of surgery, pT stage, Gleason score and lymph node involvement (all P < 0.001). The 5-year BCR-free probability was 80.6% (95% CI: 79-82.2) for NSMs vs 51% (95% CI: 47-55) for PSMs (log-rank P < 0.001). Patients with pT2 and pT3a PSMs had a similar prognosis to those with pT3a and pT3b NSMs, respectively (log-rank P ≥ 0.05)., Conclusion: A PSM after MIRP is associated with 2.14-fold increased risk of BCR. In patients with pT2 and pT3a disease, a PSM could be considered a pathological upstaging., (© 2013 The Authors. BJU International © 2013 BJU International.)
