Assessing the Impact of Positive Surgical Margins on Mortality in Patients Who Underwent Robotic Radical Prostatectomy: 20 Years' Report from the EAU Robotic Urology Section Scientific Working Group.

BACKGROUND: Positive surgical margins (PSMs) are frequent in patients undergoing radical prostatectomy (RP). The impact of PSMs on cancer-specific (CSM) and overall (OM) mortality has not yet been proved definitively. OBJECTIVE: To evaluate whether the presence and the features of PSMs were associated with CSM and OM in patients who underwent robotic-assisted RP. DESIGN, SETTING, AND PARTICIPANTS: A cohort of 8141 patients underwent robotic-assisted RP with >10 yr of follow-up. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: Cox multivariable analyses assessed the impact of margin status (positive vs negative) and PSM features (negative vs <3 mm vs >3 mm vs multifocal) on the risk of CSM, OM, and biochemical recurrence (BCR) after adjusting for potential confounders. We repeated our analyses after stratifying patients according to clinical (Cancer of the Prostate Risk Assessment [CAPRA] categories) and pathological characteristics (adverse: pT 3-4 and/or grade group [GG] 4-5 and/or pN1 and/or prostate-specific antigen [PSA] persistence). RESULTS AND LIMITATIONS: PSMs were found in 1348 patients (16%). Among these, 48 (3.6%) patients had multifocal PSMs. Overall, 1550 men experienced BCR and 898 men died, including 130 for prostate cancer. At Cox multivariable analyses, PSMs were associated with CSM in patients with adverse clinical (Intermediate risk: hazard ratio [HR]: 1.71, p = 0.048; high risk: HR: 2.20, p = 0.009) and pathological (HR: 1.79, p = 0.005) characteristics. Only multifocal PSMs were associated with CSM and OM in the whole population (HR for CSM: 4.68, p < 0.001; HR for OM: 1.82, p = 0.037) and in patients with adverse clinical (intermediate risk: HR for CSM: 7.26, p = 0.006; high risk: HR for CSM: 9.26, p < 0.001; HR for OM: 2.97, p = 0.006) and pathological (HR for CSM: 9.50, p < 0.001; HR for OM: 2.59, p = 0.001) characteristics. Potential limitations include a selection bias and a lack of information on the Gleason score at PSM location. CONCLUSIONS: We did not find an association between unifocal PSMs and mortality. Conversely, our results underscore the importance of avoiding multifocal PSMs in patients with adverse clinical (intermediate- and high-risk CAPRA score) and pathological (GG ≥4, pT ≥3, pN1, or PSA persistence) characteristics, to enhance overall survival and reduce CSM. PATIENT SUMMARY: In this study, we evaluated whether the presence and the characteristics of positive surgical margins were associated with mortality in patients who underwent robotic-assisted radical prostatectomy. We found that the presence of positive surgical margins, particularly multifocal margins, was associated with mortality only in patients with adverse clinical and pathological characteristics.

Prostate Cancer-specific and All-cause Mortality After Robot-assisted Radical Prostatectomy: 20 Years' Report from the European Association of Urology Robotic Urology Section Scientific Working Group.

BACKGROUND: Evidence on long-term oncological efficacy is available only for open radical prostatectomy but remains scarce for robot-assisted radical prostatectomy (RARP). OBJECTIVE: To validate the long-term survival rates after RARP and provide stratified outcomes based on contemporary prostate cancer (PCa) risk-stratification tools. DESIGN, SETTING, AND PARTICIPANTS: A retrospective analysis of the European Association of Urology (EAU) Robotic Urology Section Scientific Working Group international multicenter database for RARP was performed. Patients who underwent RARP at seven pioneer robotic urology programs in Europe and the USA between 2002 and 2012 were included. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: The primary outcomes were PCa-specific mortality and all-cause mortality. The probability of cancer-specific survival (CSS) was estimated with the competing risks method, and the probability of overall survival (OS) was estimated with the Kaplan-Meier method. RESULTS AND LIMITATIONS: A total of 9876 patients who underwent RARP between 2002 and 2012 were included. Within follow-up, 1071 deaths occurred and 159 were due to PCa. At 15 yr of follow-up, CSS and OS were 97.6% (97.2%, 98.0%) and 85.5% (84.6%, 86.4%), respectively. Stratified analyses based on EAU risk groups at diagnosis and pT stage showed favorable survival rates, with low-risk (n = 4601, 46.6%), intermediate-risk (n = 4056, 41.1%), and high-risk (n = 1219, 12.3%) patients demonstrating CSS rates of 99%, 98%, and 90% at 15 yr, respectively. Notably, patients with pT3a disease had similar survival outcomes to those with pT2 disease, with worse CSS in patients with pT3b PCa (98.9% vs 97.4% vs 86.5%). Multivariable analyses identified age, prostate-specific antigen, biopsy Gleason grade group, clinical T stage, and treatment year as independent predictors of worse oncological outcomes. CONCLUSIONS: Our multicenter study with long-term follow-up confirms favorable survival outcomes after RARP for localized PCa. Patients with low- and intermediate-risk disease face a higher risk of mortality from causes other than PCa. On the contrary, high-risk patients have a significantly higher risk of PCa-specific mortality. PATIENT SUMMARY: In the present study, we reported the outcomes of patients with prostate cancer (PCa) who underwent robot-assisted radical prostatectomy between 10 and 20 yr ago, and we found a very low probability of dying from PCa in patients with low- and intermediate-risk PCa.

Retrograde Extraperitoneal Laparoscopic Prostatectomy (RELP). A Prospective Study about 1,000 Consecutive Patients, with Oncological and Functional Results.

PURPOSE: Usual laparoscopic surgery of localized prostate cancer uses antegrade dissection. We describe and evaluate the original RELP (Retrograde Extraperitoneal Laparoscopic Prostatectomy). MATERIALS AND METHODS: A prospective cohort of 1005 patients with clinical localized cancer prostate were operated from December 1999 to September 2013, in Lyon (France), and followed up to 172 months (median: 60 months). Patients encountered a RELP procedure, a totally extra-peritoneal approach with a retrograde dissection from the apex to the bladder neck, and ascending dissection of the erectile neurovascular bundles, facilitated by the 30° optic telescope. Adjunctive treatments were: immediate radiotherapy (9.2%), salvage radiotherapy (13.4%), androgen deprivation therapy (10.8%), chemotherapy (1.4%), no treatment (75.8%). Results The mean age was 63.4, the Gleason score was 4+3 or worse in 24.9%, there were 2.3% unifocal tumors. The pathology stages were pT2A (8.71%), pT2B (2.80%), pT2C (69.0%), pT3A (13.1%), and pT3B (6.41%). There were 60.8% negative margins (R0) in total (90.1% for basal locations, and 75.8% for apical locations). The mean operating time was 115 minutes for the last 100 patients. The BPFSR (biological progression free survival rate, PSA≤0.10 ng/ml) was 71.9% at 5 years, and 61.4% at 10 years. The cancer specific survival rate was 99.4% at 5 years, and 98.3% at 10 years. After 12 months, 88.6% of patients did not require an incontinence pad, and 67.0% retained the pre-operative quality of their erection. CONCLUSION: RELP yields good oncologic results and quality of life, as good as robot-assisted surgery.

Best Practices in Robotic-assisted Repair of Vesicovaginal Fistula: A Consensus Report from the European Association of Urology Robotic Urology Section Scientific Working Group for Reconstructive Urology.

CONTEXT: Surgical repair of a vesicovaginal fistula (VVF) has been described extensively in the literature for several decades. Advances in robotic repair have been adopted since 2005. OBJECTIVE: A consensus review of existing data based on published case series, expert opinion, and a survey monkey. EVIDENCE ACQUISITION: This document summarizes the consensus group meeting and survey monkey results convened by the European Association of Urology Robotic Urology Section (ERUS) relating to the robotic management of VVF. EVIDENCE SYNTHESIS: Current data underline the successful robotic repair of supratrigonal nonobstetric VVF. The panel recommends preoperative marking of the fistula by a guidewire or ureteral catheter, and placement of a protective ureteral JJ stent. An extravesical robotic approach usually provides a good anatomic view for adequate and wide dissection of the vesicovaginal space, as well as bladder and vaginal mobilization. Careful sharp dissection of fistula edges should be performed. Tension-free closure of the bladder is of utmost importance. Tissue interposition seems to be beneficial. The success rate of published series often reaches near 100%. An indwelling bladder catheter should be placed for about 10 d postoperatively. CONCLUSIONS: When considering robotic repair for VVF, it is essential to establish the size, number, location, and etiology of the VVF. Robotic assistance facilitates dissection of the vesicovaginal space, harvesting of a well-vascularized tissue flap, and a tension-free closure of the bladder with low morbidity for the patient being operated in the deep pelvis with delicate anatomical structures. PATIENT SUMMARY: Robotic repair of a vesicovaginal fistula can be applied safely with an excellent success rate and very low morbidity. This confirms the use of robotic surgery for vesicovaginal fistula repair, which is recommended in a consensus by the European Association of Urology Robotic Section Scientific Working Group for reconstructive urology.

Prognostic factors and long-term outcomes of obstetric fistula care using the Tanguiéta model.

OBJECTIVES: To identify factors influencing the long-term prognosis after surgical repair of obstetric fistula, establish a prognosis-based classification system, and examine changes in quality of life after surgery. METHODS: A retrospective study of 308 women who underwent obstetric fistula repair at Saint Jean de Dieu Hospital, Tanguiéta, Benin, between 2008 and 2016, and were supported by a multidisciplinary management model. All participants were from rural areas of Burkina Faso. The women completed interviews before, immediately after, and 2, 4-6, and 12 months after surgery to assess their clinical state and socioeconomic and psychologic status. RESULTS: Overall, the fistulae of 230/274 (83.9%) women were considered to be repaired after 12 months. Factors associated with poor repair outcome included the presence of sclerotic tissue (odds ratio [OR], 0.25; 95% confidence interval [CI], 0.11-0.53) and intraoperative complications (OR, 0.16; 95% CI, 0.07-0.39). Women with successful surgery had a better quality of life as compared with women with an unrepaired fistula (Ditrovie score, 1.1 vs 3.9; P<0.001). CONCLUSION: The multidisciplinary Tanguiéta model for management of obstetric fistula allowed successful fistula closure, thereby facilitating the women's long-term social reintegration, and improved quality of life.

Robotic and Open Radical Prostatectomy: The First Prospective Randomised Controlled Trial Fuels Debate Rather than Closing the Question.

Despite the finally acquired level 1 evidence, the urologic debate on open versus robotic prostatectomy still persists. This trial from Brisbane will encourage future studies that will better inform this debate and define what robotic surgery offers.

One-year follow-up of women who participated in a physiotherapy and health education program before and after obstetric fistula surgery.

OBJECTIVE: To investigate whether the positive impact of a program of physiotherapy and health education on the outcome of obstetric fistula surgery was maintained after 1 year. METHODS: The present follow-up analysis included 108 women who underwent obstetric fistula surgery at a center in Tanguiéta, Benin, between March 2011 and March 2012, and who had received a structured program of physiotherapy and health education before and after surgery. After discharge, follow-up visits were made 3, 6, and 12 months after surgery. The Ditrovie scale was used to measure quality of life (QoL), and continence and performance of the physiotherapy exercises were assessed. RESULTS: Mean QoL score was 36.9 (range 16.0-49.0) before surgery. Overall, 84 women were followed up for 1 year. Their mean QoL score had improved significantly to 18.5 (range 10.0-47.0; P<0.001). Between hospital discharge and 1 year, the number of women with a closed fistula increased from 48 (57.1%) to 53 (63.1%) and the number with urinary stress incontinence reduced from 11 (13.1%) to 9 (10.7%). CONCLUSION: Results obtained after surgery and physiotherapy were maintained at 1 year, and QoL had improved significantly. When women are encouraged to continue exercises, improvements are also seen in residual stress incontinence.

Impact of a program of physiotherapy and health education on the outcome of obstetric fistula surgery.

OBJECTIVE: Surgery is the only successful treatment for most obstetric fistulae. The present study measured the impact of a structured program of pre- and postoperative physiotherapy and health education on the outcome of surgery for obstetric fistula. METHODS: We compared the postoperative outcomes of 2 consecutive groups of women with obstetric fistulae who were recruited and followed-up by 2 local nongovernmental organizations at a hospital in Tanguiéta, Benin. The first group of women (n=99) had fistula repair using standardized techniques. The second group (n=112) had a standardized surgical approach plus a structured program of pre- and postoperative health education and physiotherapy. RESULTS: The program had a significant positive impact on recovery in general and on urinary incontinence in particular. After physiotherapy, the odds of recovery were 2.72 times greater for women in the physiotherapy group than for control patients, and the probability of postoperative stress incontinence was considerably higher for patients in the control group than for those in the physiotherapy group (P<0.001). CONCLUSION: A structured program of health education and physiotherapy by experienced nurses and physiotherapists improves the likelihood of a successful outcome after surgical repair of obstetric fistula.

The European Association of Urology Robotic Urology Section (ERUS) survey of robot-assisted radical prostatectomy (RARP).

OBJECTIVE: To evaluate surgeons adherence to current clinical practice, with the available evidence, for robot-assisted radical prostatectomy (RARP) and offer a baseline assessment to measure the impact of the Pasadena recommendations. Recently, the European Association of Urology Robotic Urology Section (ERUS) supported the Pasadena Consensus Conference on best practices in RARP. SUBJECTS AND METHODS: This survey was performed in January 2012. A specific questionnaire was sent, by e-mail, to 145 robotic surgeons who were included in the mailing-list of ERUS members and working in different urological institutions. Participating surgeons were invited to answer a multiple-choice questionnaire including 24-items evaluating the main RARP surgical steps. RESULTS: In all, 116 (79.4%) invited surgeons answered the questionnaire and accepted to participate to the ERUS survey. In all, 47 (40.5%) surgeons performed >100 RARPs; 41 (35.3%) between 50 and 100, and 28 (24.1%) <50 yearly. The transperitoneal, antegrade technique was the preferred approach. Minimising bladder neck dissection and the use of athermal dissection of the neurovascular bundles (NVBs) were also popular. There was more heterogeneity in the use of energy for seminal vesicle dissection, the preservation of the tips of the seminal vesicle and the choice between intra- and interfascial planes during the antero-lateral dissection of the NVBs. There was also large variability in the posterior and/or anterior reconstruction steps. CONCLUSIONS: The present study is the first international survey evaluating surgeon preferences during RARP. Considering that the results were collected before the publication of the Pasadena recommendations, the data might be considered an important baseline evaluation to test the dissemination and effects of the Pasadena recommendations in subsequent years.

Risk factors for obstetric fistula: a clinical review.

Obstetric fistula is the presence of a hole between a woman's genital tract and either the urinary or the intestinal tract. Better knowledge of the risk factors for obstetric fistula could help in preventing its occurrence. The purpose of this study was to assess the characteristics of obstetric fistula patients. We conducted a search of the literature to identify all relevant articles published during the period from 1987-2008. Among the 19 selected studies, 15 were reports from sub-Saharan Africa and 4 from the Middle East. Among the reported fistula cases, 79.4% to 100% were obstetrical while the remaining cases were from other causes. Rectovaginal fistulae accounted for 1% to 8%, vesicovaginal fistulae for 79% to 100% of cases, and combined vesicovaginal and rectovaginal fistulae were reported in 1% to 23% of cases. Teenagers accounted for 8.9% to 86% of the obstetrical fistulae patients at the time of treatment. Thirty-one to 67% of these women were primiparas. Among the obstetric fistula patients, 57.6% to 94.8% of women labor at home and are secondarily transferred to health facilities. Nine to 84% percent of these women delivered at home. Many of the fistula patients were shorter than 150 cm tall (40-79.4%). The mean duration of labor among the fistula patients ranged from 2.5 to 4 days. Twenty to 95.7% of patients labored for more than 24 h. Operative delivery was eventually performed in 11% to 60% of cases. Obstetric fistula was associated with several risk factors, and they appear to be preventable. This knowledge should be used in strengthening the preventive strategy both at the health facility and at the community level.

Mid-term biochemical recurrence-free outcomes following robotic versus laparoscopic radical prostatectomy.

We compared 5-year biochemical recurrence (BCR)-free rates for robotic-assisted laparoscopic prostatectomy (RALP) and laparoscopic radical prostatectomy (LRP). Three hundred and twelve consecutive patients who underwent RALP from 2003 to 2008 were compared to 97 consecutive LRP patients from 1999 to 2004. All laparoscopic surgeries were performed by one surgeon and robotic surgeries were performed by this surgeon or a laparoscopically naïve surgeon. Both groups were evaluated for perioperative outcome, pathologic status, and mid-term oncologic outcomes (5-year BCR-free rates at prostate-specific antigen [PSA] cutoffs of <0.4, <0.2, or <0.1 ng/ml). Baseline characteristics were equivalent except for age (61.9 years vs. 65.1 years, P < 0.0001). RALP operating time was shorter (215.5 min vs. 305.3, P < 0.0001), and resulted in fewer complications (3.8% vs. 10.3%, P = 0.0214) and blood transfusions (2.9% vs. 13.4%, P = 0.0003). Positive surgical margins were equivalent (pT2 20.9% vs. 28.8%, P = 0.1818). Overall 5-year BCR-free rates were comparable for RALP (97.6, 93.4, and 85.1%) and LRP (97.7, 89.7, and 79.7%) at PSA cutoff levels of <0.4, <0.2, and <0.1 ng/ml, respectively. There was a significant difference in BCR-free rates between the RALP and LRP groups for patients with organ-confined (pT2) disease at 0.2 ng/ml (96.4% vs. 88.7%, P = 0.0373) and 0.1 ng/ml (91.0% vs. 83.0%, P = 0.0470). We report lower morbidity, comparable pathologic outcome and improved mid-term oncologic results in patients with organ-confined disease after RALP in comparison to LRP.

Quality care in vesico-vaginal obstetric fistula: case series report from the regional hospital of Maroua-Cameroon.

The World Health Organization (WHO) proposes a successful closure rate for first repair of vesico-vaginal obstetric fistula to be at 85% in each facility, with the continence achievement among the closed cases at 90 %. We are reporting the vesico-vaginal obstetric fistula outcome at the provincial hospital of Maroua-Cameroon from 2005 to August 2007. Among the overall 32 patients with vesico-vaginal fistula operated, 25 patients were at their first operation. The complete closure of vesico-vaginal fistula (VVF) was 23/25 (92%) and among the 23 patients with complete closure 17(74%) had good continence. When we consider only the 25 patients who were at their first operation, the overall closure of VVF was 23/25 (92%) and among them 17/23 (74%) were continent. Large lesion, bladder neck lesions, vaginal adherence and rigid margin are associated with failure/incontinence. These factors must be taken into consideration when preparing patients for surgery or when assigning them to a surgeon within the surgical team.

Risk factors for obstetric fistula in the Far North Province of Cameroon.

OBJECTIVE: To describe the circumstances of occurrence and identify potential risk factors for obstetric fistula in northern Cameroon. METHODS: A case series study of 42 obstetric fistula patients seeking services at the Provincial Hospital of Maroua, Cameroon, between May 2005 and August 2007. Structured interviews were conducted prior to surgical intervention. RESULTS: Among obstetric fistula patients, 60% had lived with obstetric fistula for more than 5 years at the time of surgery. Eighty-one percent of patients had received no formal education and 86% were teenagers at their first delivery. Regarding the pregnancy and delivery preceding the occurrence of the fistula, 50% of women reported that they had received no prenatal care and 76% were in labor for more than 12 hours. The majority (83%) of women delivered a stillborn baby. CONCLUSIONS: Obstetric fistula patients in the Far North Province of Cameroon had a low level of education, were married at a young age, and had poor access to quality maternal healthcare services.
