Oncological outcomes after attempted nerve-sparing radical prostatectomy (NSRP) in patients with high-risk prostate cancer are comparable to standard non-NSRP: a longitudinal long-term propensity-matched single-centre study.

OBJECTIVE: To assess the long-term safety of nerve-sparing radical prostatectomy (NSRP) in men with high-risk prostate cancer (PCa) by comparing survival outcomes, disease recurrence, the need for additional therapy, and perioperative outcomes of patients undergoing NSRP to those having non-NSRP. PATIENTS AND METHODS: We included consecutive patients at a single, academic centre who underwent open RP for high-risk PCa, defined as preoperative prostate-specific antigen level of > 20 ng/mL and/or postoperative International Society of Urological Pathology Grade Group 4 or 5 (i.e., Gleason score ≥ 8) and/or ≥pT3 and/or pN1 assessing the RP and lymph node specimen. We calculated a propensity score and used inverse probability of treatment weighting to match baseline characteristics of patients with high-risk PCa who underwent NSRP vs non-NSRP. We analysed oncological outcome as time-to-event and calculated hazard ratios (HRs). RESULTS: A total of 726 patients were included in this analysis of which 84% (n = 609) underwent NSRP. There was no evidence for the positive surgical margin rate being different between the NSRP and non-NSRP groups (47% vs 49%, P = 0.64). Likewise, there was no evidence for the need for postoperative radiotherapy being different in men who underwent NSRP from those who underwent non-NSRP (HR 0.78, 95% confidence interval [CI] 0.53-1.15). NSRP did not impact the risk of any recurrence (HR 0.99, 95% CI 0.73-1.34, P = 0.09) and there was no evidence for survival being different in men who underwent NSRP to those who underwent non-NSRP (HR 0.65, 95% CI 0.39-1.08). There was also no evidence for the cancer-specific survival (HR 0.56, 95% CI 0.29-1.11) or progression-free survival (HR 0.99, 95% CI 0.73-1.34) being different between the groups. CONCLUSION: In patients with high-risk PCa, NSRP can be attempted without compromising long-term oncological outcomes provided a comprehensive assessment of objective (e.g., T Stage) and subjective (e.g., intraoperative appraisal of tissue planes) criteria are conducted.

Impact of the extent of lymph node dissection on survival outcomes in clinically lymph node-positive bladder cancer.

OBJECTIVE: To determine the oncological impact of extended pelvic lymph node dissection (ePLND) vs standard PLND (sPLND) during radical cystectomy (RC) in clinically lymph node-positive (cN+) bladder cancer (BCa). PATIENTS AND METHODS: In this retrospective, multicentre study we included 969 patients who underwent RC with sPLND (internal/external iliac and obturator lymph nodes) or ePLND (sPLND plus common iliac and presacral nodes) with or without platin-based peri-operative chemotherapy for cTany N1-3 M0 BCa between 1991 and 2022. We assessed the impact of ePLND on recurrence-free survival (RFS) and the distribution of recurrences (locoregional and distant recurrences). The secondary endpoint was overall survival (OS). We performed propensity-score matching using covariates associated with the extent of PLND in univariable logistic regression analysis. The association of the extent of PLND with RFS and OS was investigated using Cox regression models. RESULTS: Of 969 cN+ patients, 510 were 1:1 matched on propensity scores. The median (interquartile range [IQR]) time to recurrence was 8 (4-16) months, and median (IQR) follow-up of alive patients was 30 (13-51) months. Disease recurrence was observed in 104 patients in the ePLND and 107 in the sPLND group. Of these, 136 (27%), 47 (9.2%) and 19 patients (3.7%) experienced distant, locoregional, or both distant and locoregional disease recurrence, respectively. When stratified by the extent of PLND, we did not find a difference in recurrence patterns (P > 0.05). ePLND improved neither RFS (hazard ratio [HR] 0.91, 95% confidence interval [CI] 0.70-1.19; P = 0.5) nor OS (HR 0.78, 95% CI 0.60-1.01; P = 0.06) compared to sPLND. Stratification by induction chemotherapy did not change outcomes. CONCLUSION: Performing an ePLND at the time of RC in cN+ patients improved neither RFS nor OS compared to sPLND, regardless of induction chemotherapy status. Pretreatment risk stratification is paramount to identify ideal candidates for RC with ePLND as part of a multimodal treatment approach.

The optimal number of induction chemotherapy cycles in clinically lymph node-positive bladder cancer.

OBJECTIVE: To investigate the optimal number of induction chemotherapy cycles needed to achieve a pathological response in patients with clinically lymph node-positive (cN+) bladder cancer (BCa) who received three or four cycles of induction chemotherapy followed by consolidative radical cystectomy (RC) with pelvic lymph node dissection. PATIENTS AND METHODS: We included 388 patients who received three or four cycles of cisplatin/gemcitabine or (dose-dense) methotrexate, vinblastine, doxorubicin, and cisplatin (MVAC), followed by consolidative RC for cTanyN1-3M0 BCa. We compared pathological complete (pCR = ypT0N0) and objective response (pOR = yp ≤T1N0) between treatment groups. Predictors of pCR and/or pOR were assessed using uni- and multivariable logistic regression analysis. The secondary endpoints were overall (OS) and cancer-specific survival (CSS). We evaluated the association between the number of induction chemotherapy cycles administered and survival outcomes on multivariable Cox regression. RESULTS: Overall, 101 and 287 patients received three or four cycles of induction chemotherapy, respectively. Of these, 72 (19%) and 128 (33%) achieved pCR and pOR response, respectively. The pCR (20%, 18%) and pOR (40%, 31%) rates did not differ significantly between patients receiving three or four cycles (P > 0.05). The number of cycles was not associated with pCR or pOR on multivariable logistic regression analyses. The 2-year OS estimates were 63% (95% confidence interval [CI] 0.53-0.74) and 63% (95% CI 0.58-0.7) for patients receiving three or four cycles, respectively. Receiving three vs four cycles was not associated with OS and CSS on uni- or multivariable Cox regression analyses. CONCLUSION: Pathological response and survival outcomes did not differ between administering three or four induction chemotherapy cycles in patients with cN+ BCa. A fewer cycles (minimum three) may be oncologically sufficient in patients with cN+ BCa, while decreasing the wait for definitive local therapy in those patients who end up without a response to chemotherapy. This warrants further validation.

Sacral neuromodulation in the management of chronic pelvic pain: A systematic review and meta-analysis.

INTRODUCTION: Sacral neuromodulation (SNM) is a treatment approved for use in several conditions including refractory overactive bladder (OAB) and voiding dysfunction. Chronic pelvic pain (CPP) is a debilitating condition for which treatment is often challenging. SNM shows promising effect in patients with refractory CPP. However, there is a lack of clear evidence, especially in long-term outcomes. This systematic review will assess outcomes of SNM for treating CPP. METHODS: A systematic search of MEDLINE, Embase, Cochrane Central and clinical trial databases was completed from database inception until January 14, 2022. Studies using original data investigating SNM in an adult population with CPP which recorded pre and posttreatment pain scores were selected. Primary outcome was numerical change in pain score. Secondary outcomes were quality of life assessment and change in medication use and all-time complications of SNM. Risk of bias was assessed using the Newcastle Ottawa Tool for cohort studies. RESULTS: Twenty-six of 1026 identified articles were selected evaluating 853 patients with CPP. The implantation rate after test-phase success was 64.3%. Significant improvement of pain scores was reported in 13 studies; three studies reported no significant change. WMD in pain scores on a 10-point scale was -4.64 (95% confidence interval [CI] = -5.32 to -3.95, p < 0.00001) across 20 studies which were quantitatively synthesized: effects were maintained at long-term follow-up. Mean follow-up was 42.5 months (0-59). Quality of life was measured by RAND SF-36 and EQ-5D questionnaires and all studies reported improvement in quality of life. One hundred and eighty-nine complications were reported in 1555 patients (Clavien-Dindo Grade I-IIIb). Risk of bias ranged from low to high risk. Studies were case series and bias stemmed from selection bias and loss to follow-up. CONCLUSION: Sacral Neuromodulation is a reasonably effective treatment of Chronic Pelvic Pain and significantly reduces pain and increases patients' quality of life with immediate to long-term effects.

Perioperative continuation of aspirin, oral anticoagulants or bridging with therapeutic low-molecular-weight heparin does not increase intraoperative blood loss and blood transfusion rate in cystectomy patients: an observational cohort study.

OBJECTIVE: To assess if uninterrupted anticoagulant agents' administration affects blood loss and blood transfusion during open radical cystectomy (RC) and urinary diversion. PATIENTS AND METHODS: We conducted an observational single-centre cohort study of a consecutive series of 1430 RC patients, between 2000 and 2020. Blood loss was depicted according to body weight and duration of surgery (mL/kg/h), and blood transfusion. The group 'with anticoagulant agents' was considered if surgery was performed with uninterrupted low-dose aspirin (ASS), oral anticoagulants (OAC) with an international normalised ratio (INR) goal of 2-2.5 or bridging with therapeutic low-molecular-weight heparin (LMWH). Outcomes were intraoperative blood loss, blood transfusion rate (separately analysed if administered within 24 h perioperatively or >24 h after surgery) and the 90-day major adverse cardiac events (MACE) rate. We used propensity score (PS)-matching analysis to adjust for imbalances between groups with or without anticoagulant agents. RESULTS: The PS-matched median (interquartile range [IQR]) blood loss was 2.10 (1.50-2.94) mL/kg/h in patients with anticoagulant agents vs 2.11 (1.47-2.94) mL/kg/h without anticoagulant agents (Padj > 0.99). The PS-matched blood transfusion rates were 26.2% vs 35.1% (Padj = 0.875) within 24 h perioperatively and 57.0% vs 55.0% (Padj = 0.680) if administered >24 h postoperatively. A sub-analysis of the three different anticoagulant agents could not detect any significance between ASS, OAC, or LMWH. The PS-matched incidence of MACE was 9.1% in the group with anticoagulant agents and 8.1% in those without anticoagulant agents (Padj > 0.99). Limitations include selection bias and retrospective analysis from prospectively assessed data. CONCLUSIONS: Perioperative continuation of ASS, uninterrupted OAC with low INR goal or bridging with LMWH had no impact on blood loss and transfusion rate in RC patients. Therefore, there might be no compulsory need for discontinuation of anticoagulant agents.

A longitudinal study evaluating interim assessment of neoadjuvant chemotherapy for bladder cancer.

OBJECTIVES: To evaluate the usefulness of radiological re-staging after two and four cycles of neoadjuvant chemotherapy (NAC), the impact of re-staging on further patient management, and the correlation between clinical and final pathological tumour stage at radical cystectomy (RC). PATIENTS AND METHODS: We conducted a longitudinal, single-centre, cohort study of prospectively collected consecutive patients who underwent NAC and RC for urothelial muscle-invasive bladder cancer between July 2001 and December 2017. Patients underwent repeated computed tomography scans for re-staging after two cycles of NAC and after completion of NAC before RC. RESULTS: Of 180 patients, 110 had ≥four cycles of NAC and had complete imaging available. In the entire cohort, further patient management was only changed in 2/180 patients (1.1%) after two cycles of NAC based on radiological findings. Patients who were stable after two cycles but then downstaged after at least four cycles of NAC had a similarly lowered risk of death (hazard ratio [HR] 0.53). Only one patient downstaged after two cycles was subsequently upstaged after four cycles. Clinical downstaging was observed in 51 patients (46%), 55 patients (50%) had no change in clinical stage and four patients (3.6%) were clinically upstaged. Patients clinically downstaged after four cycles of NAC had a lower risk of death (HR 0.49, 95% confidence interval 0.25-0.94; P = 0.033) compared to those with no change or upstaged after completion of NAC. CONCLUSIONS: Re-staging of muscle-invasive bladder cancer after two cycles of NAC offers little additional information, rarely changes patient management, and may therefore be omitted, whereas re-staging after completion of NAC by CT is a strong predictor of overall survival.

A comparative study of peri-operative outcomes for 100 consecutive post-chemotherapy and primary robot-assisted and open retroperitoneal lymph node dissections.

PURPOSE: To describe and compare differences in peri-operative outcomes of robot-assisted (RA-RPLND) and open (O-RPLND) retroperitoneal lymph node dissection performed by a single surgeon where chemotherapy is the standard initial treatment for Stage 2 or greater non-seminomatous germ cell tumour. METHODS: Review of a prospective database of all RA-RPLNDs (28 patients) and O-RPLNDs (72 patients) performed by a single surgeon from 2014 to 2020. Peri-operative outcomes were compared for patients having RA-RPLND to all O-RPLNDs and a matched cohort of patients having O-RPLND (20 patients). Further comparison was performed between all patients in the RA-RPLND group (21 patients) and matched O-RPLND group (18 patients) who had previous chemotherapy. RA-RPLND was performed for patients suitable for a unilateral template dissection. O-RPLND was performed prior to the introduction of RA-RPLND and for patients not suitable for RA-RPLND after its introduction. RESULTS: RA-RPLND showed improved peri-operative outcomes compared to the matched cohort of O-RPLND-median blood loss (50 versus 400 ml, p < 0.00001), operative duration (150 versus 195 min, p = 0.023) length-of-stay (1 versus 5 days, p < 0.00001) and anejaculation (0 versus 4, p = 0.0249). There was no statistical difference in complication rates. RA-RPLND had lower median lymph node yields although not significant (9 versus 13, p = 0.070). These improved peri-operative outcomes were also seen in the post-chemotherapy RA-RPLND versus O-RPLND analysis. There were no tumour recurrences seen in either group with median follow-up of 36 months and 60 months, respectively. CONCLUSIONS: Post-chemotherapy RA-RPLND may have decreased blood loss, operative duration, hospital length-of-stay and anejaculation rates in selected cases and should, therefore, be considered in selected patients. Differences in oncological outcomes require longer term follow-up.

Impact of early postoperative creatinine increase on mid-term renal function after cystectomy.

OBJECTIVES: To determine whether early acute kidney injury affects mid-term renal function, to identify risk factors for impaired mid-term renal function, and to highlight the evolution of plasma creatinine and estimated glomerular filtration rate in the first 12 months after cystectomy and urinary diversion. METHODS: We conducted a single-center retrospective observational cohort study from 2000 to 2019. We included 900 consecutive patients undergoing cystectomy and urinary diversion. Patients with incomplete data and preoperative hemodialysis were excluded. Early acute kidney injury was defined as an increase in plasma creatinine of >50% or >26.5 µmol/L within 24 h after surgery. Multiple linear regression analysis was performed to model the association between risk factors and change in plasma creatinine and estimated glomerular filtration rate at 12 months. RESULTS: Early acute kidney injury was diagnosed in 183/900 patients (20.3%) and was associated with significant mid-term plasma creatinine increase compared to preoperative value (+10.0 µmol/L [95% confidence interval -1.5, 25.0] vs +4.0 µmol/L [-7.0, 13.0]; P < 0.001). Similarly, a significant estimated glomerular filtration rate change was found (-11.2 mL/min [95% confidence interval -19.8, 0.6] vs -4.9 mL/min [-15.6, 5.3]; P < 0.001). In the linear regression model, early acute kidney injury increased creatinine at 12 months by 9.8% (estimated glomerular filtration rate: decrease by 6.2 mL/min), male sex by 12.0%. Limitations include retrospective analysis from prospectively assessed data. CONCLUSIONS: Early acute kidney injury resulted in elevated plasma creatinine and decreased estimated glomerular filtration rate values 12 months postoperatively, albeit the clinical relevance remains questionable.

Seminal Vesical Sparing Cystectomy for Bladder Cancer is Feasible with Good Functional Results without Impairing Oncological Outcomes: A Longitudinal Long-Term Propensity-Matched Single Center Study.

PURPOSE: Seminal vesicle-sparing radical cystectomy has been reported to improve short-term functional results without compromising oncological outcomes. However, there is still a lack of data on long-term outcomes after seminal vesicle-sparing radical cystectomy. The aim of this study was to compare oncological and functional outcomes in patients after seminal vesicle-sparing vs nonseminal vesicle-sparing radical cystectomy. MATERIALS AND METHODS: Oncological and functional outcomes of 470 consecutive patients after radical cystectomy and orthotopic ileal reservoir from 2000 to 2017 were evaluated. They were stratified into 6 groups according to nerve-sparing and seminal vesicle-sparing status as attempted during surgery: no sparing at all (55), unilateral nerve sparing (159), bilateral nerve sparing (132), unilateral seminal vesicle-sparing and unilateral nerve sparing (30), unilateral seminal vesicle sparing and bilateral nerve sparing (45), and bilateral seminal vesicle sparing (49) and used propensity modeling to adjust for preoperative differences. RESULTS: Median followup among the entire cohort was 64 months. Among the 6 groups, our analysis showed no difference in local recurrence-free survival (p=0.173). However, progression-free, cancer-specific and overall survival were more favorable in patients with seminal vesicle-sparing radical cystectomy (p <0.001, p=0.006 and p <0.001, respectively). Proportions of patients with erectile function recovery were higher in the seminal vesicle-sparing groups at all time points in all analyses, respectively, with pronounced earlier recovery in patients with bilateral seminal vesicle sparing. Importantly, patients with seminal vesicle sparing were significantly less in need of erectile aids to achieve erection and intercourse. Over the whole period, daytime urinary-continence was significantly better in the seminal vesicle sparing groups (OR 2.64 to 5.21). CONCLUSIONS: In a highly selected group of patients, seminal vesicle sparing radical cystectomy is oncologically safe and results in excellent functional outcomes that are reached at an earlier time point after surgery and remain superior over a longer period of time.

Surgical safety in radical cystectomy: the anesthetist's point of view-how to make a safe procedure safer.

PURPOSE: The aim of this review is to present an anesthesiological overview on surgical safety for radical cystectomy implementing the cornerstones of today's rapidly evolving field of perioperative medicine. METHODS: This is a narrative review of current perioperative medicine and surgical safety concepts for major surgery in general with special focus on radical cystectomy. RESULTS: The tendency for perioperative care and surgical safety is to consider it a continuous proactive pathway rather than a single surgical intervention. It starts at indication for surgery and lasts until full functional recovery. Preoperative optimization leads to superior outcome by mobilizing and/or increasing physiological reserve. Multidisciplinary teamwork involving all the relevant parties from the beginning of the pathway is crucial for outcome rather than an isolated specialist approach. This fact has gained importance in times of an ageing frail population and rising health care cost. We also present our 2019 Cystectomy Enhanced Recovery Approach for optimization of perioperative care for open radical cystectomy in a high caseload center. CONCLUSIONS: With the implementation of in itself simple but crucial steps in perioperative medicine such as multimodal prehabilitation, safety checks, better perioperative monitoring and enhanced recovery concepts, even complex surgical procedures such as radical cystectomy can be performed safer. Emphasis has to be laid on a more global view of the patients' path through the perioperative process than on the surgical procedure alone.

A treatment strategy to help select patients who may not need secondary intervention to remove symptomatic ureteral stones after previous stenting.

PURPOSE: This study aimed at evaluating whether removal of the ureteral stent the day before scheduled secondary intervention facilitates spontaneous ureteral stone passage and thus can spare the pre-stented patient this surgery. METHODS: Retrospective analysis of a single-centre consecutive series of 216 patients after previous stenting due to a symptomatic ureteral stone from 01/2013 to 01/2018. Indwelling stents were removed under local anaesthesia. Patients were told to filter their urine overnight. Multivariate analysis was performed to assess predictive factors for spontaneous stone passage. RESULTS: 34% (74/216) of patients had spontaneous stone passage while the stent was indwelling. Of the remaining 142 patients, 41% (58/142) had spontaneous stone passage within 24 h after stent removal. Only 84/216 (39%) patients needed secondary intervention. Multivariate logistic regression analysis of all 216 patients showed a significant association between spontaneous stone passage and smaller stone size (p < 0.001), distal stone location (p = 0.046) and stent dwell time (p = 0.02). Predictive factors for spontaneous stone passage after stent removal were smaller size (p < 0.001), distal location (p = 0.001), and stone movement while the stent was indwelling (p = 0.016). A treatment strategy was established that helps select patients suitable for conservative management. CONCLUSIONS: The majority (61%) of ureteral stones passed spontaneously after pre-stenting; 34% while the stent was indwelling, 27% within 24 h after stent removal. Besides distal stone location, stone size (< 6 mm) and stone movement (≥ 5 cm) while the stent is indwelling indicate patients who are likely to pass their ureteral stone spontaneously after stent removal. The treatment strategy (decision tree) presented here helps identify those patients. TRIAL REGISTRATION: https://doi.org/10.1186/ISRCTN12112914 .

Intra-operative norepinephrine administration and cancer-related outcomes following radical cystectomy for bladder cancer: A cohort study.

BACKGROUND: The impact of anaesthetic techniques on recurrence of cancers is controversial. Elevated plasma catecholamine levels have been implicated in angiogenesis and metastasis in various cancers. OBJECTIVES: To assess the potential association between continuous intra-operative norepinephrine administration and tumour-related outcome in muscle-invasive bladder cancer patients undergoing radical cystectomy with urinary diversion. DESIGN: Retrospective observational cohort study. SETTING: Single tertiary centre, from 2000 to 2017. PATIENTS: We included a consecutive series of 1120 urothelial carcinoma patients undergoing radical cystectomy and urinary diversion, including 411/1120 patients (37%) who received a continuous intra-operative administration of more than 2 µg kg BW h norepinephrine. MAIN OUTCOME MEASURES: The primary outcome was time to tumour recurrence within 5 years after surgery, with death as competing outcome. We used inverse probability of treatment weighting to adjust for imbalances between treatment groups, one having received more than 2 µg kg BW h norepinephrine and the other having received less. We furthermore adjusted for intra-operative variables or years of surgery as sensitivity analyses. RESULTS: The continuous administration of more than 2 µg kg BW h norepinephrine slightly increased tumour recurrence (hazard ratio: 1.47, 95% CI 0.98 to 2.21; P = 0.061). After adjustment for intra-operative variables, and year of surgery hazard ratios were 1.82 (95% CI 1.13 to 2.91, P = 0.013) and 1.85 (95% CI 1.12 to 3.07, P = 0.017), respectively. Overall mortality (with or without tumour recurrence) was not affected by norepinephrine (hazard ratio: 0.84, 95% CI 0.65 to 1.08, P = 0.170). CONCLUSION: Continuous administration of more than 2 µg kg BW h norepinephrine was associated with a slightly increased hazard ratio for tumour recurrence if adjusted for intra-operative variables and year of surgery. This observation could reflect a low potential pro-oncogenic effect of norepinephrine during the intra-operative period. TRIAL REGISTRATION: Not applicable.

Positive Pre-cystectomy Biopsies of the Prostatic Urethra or Bladder Neck Do Not Necessarily Preclude Orthotopic Bladder Substitution.

PURPOSE: We investigated the influence of positive pre-cystectomy biopsies of the prostatic urethra in males and the bladder neck in females on urethral recurrence, cancer specific and overall survival, and functional outcomes after orthotopic bladder substitution. MATERIALS AND METHODS: We retrospectively analyzed the records of 803 consecutive patients, including 703 males and 100 females, who underwent orthotopic bladder substitution as well as pre-cystectomy biopsy of the prostatic urethra in males and the bladder neck in females, at our institution between April 1986 and December 2017. RESULTS: Pre-cystectomy biopsies were negative in 755 of the 803 patients (94%) (group 1) and positive in 48 (6%) (group 2). Biopsies in group 2 revealed carcinoma in situ in 35 of the 48 cases (73%), pTaG1/G2 in 5 (10%) and pTaG3/pT1G3 in 8 (17%). Median followup was 64 months (IQR 21-128). At a median followup of 56 months (IQR 18-127) urethral recurrence developed in 45 of the 803 patients (5.6%), including 30 of the 755 (4%) in group 1 and 15 of the 48 (31.3%) in group 2 (p <0.001). Only 10 of the 45 patients (22%) with urethral recurrence required salvage urethrectomy while locally conservative treatment was successful in 27 (60%). Of the remaining 8 patients 6 of 45 (13%) underwent synchronous palliative chemotherapy and 2 of 45 (4%) refused treatment. Multivariate regression analysis revealed a higher risk of urethral recurrence if patients had positive pre-cystectomy biopsies (group 2 HR 6.49, 95% CI 3.33-12.62, p <0.001) or received neoadjuvant or adjuvant chemotherapy (HR 3.05, 95% CI 1.66-5.59, p <0.001). Cancer specific and overall survival as well as functional outcomes were similar in the 2 groups. CONCLUSIONS: Positive pre-cystectomy biopsies prior to orthotopic bladder substitution increased the urethral recurrence rate but did not lower cancer specific or overall survival. Most urethral recurrences were managed successfully by local treatment. Orthotopic bladder substitution is an option in highly selected patients with positive, noninvasive pre-cystectomy biopsies, provided that they undergo regular followup including urethral cytology.

Repeat prostate biopsies prior to radical prostatectomy do not impact erectile function recovery and mid- to long-term continence.

BACKGROUND: A growing number of men undergo repeat biopsies prior to radical prostatectomy for prostate cancer. However, the long-term impact of repeat biopsies on functional outcomes in this patient population remains unelucidated. Thus, we compared functional outcomes between patients who underwent single biopsy versus repeat biopsies before radical prostatectomy. METHODS: From 1996 to 2015, 1015 consecutive patients underwent radical prostatectomy, and subsequently had urinary continence and erectile function assessed for >2 years follow-up. One-fourth of patients (275; 27%) had ≥2 biopsies before prostatectomy. Logistic regression models tested whether repeat biopsy before prostatectomy predicted continence or erectile function recovery. RESULTS: For the overall cohort, continence rates were 84%, 92%, 96%, and 98% at 3, 6, 12, and 24 months, respectively. Repeat biopsy before prostatectomy was associated with lower continence rate at 3 months compared to single biopsy (P = 0.03); however, no significant differences were observed at 6, 12, or 24 months. In multivariable analyses adjusting for age, body mass index and diabetes/cardiovascular disease/smoking, the association between repeat biopsy and lower likelihood of continence at 3 months remained (odds ratio 0.67, 95% confidence interval 0.47-0.97; P = 0.03). Overall erectile function recovery rates were 16%, 33%, 51%, and 55% at 3, 6, 12, and 24 months, respectively. No difference in erectile function recovery rates was seen at any time point for single biopsy versus repeat biopsy. In multivariable analyses, repeat biopsy was not predictive of erectile function recovery at any time point. CONCLUSIONS: Repeat biopsy before radical prostatectomy impairs early continence after surgery. However, erectile function recovery and mid-term to long-term continence are not affected. These data support the current trend towards active surveillance and delayed local treatment in patients with low- to intermediate-risk prostate cancer.

More extended lymph node dissection template at radical prostatectomy detects metastases in the common iliac region and in the fossa of Marcille.

OBJECTIVES: To assess the effect of adding lymph nodes (LNs) located along the common iliac vessels and in the fossa of Marcille to the extended pelvic LN dissection (PLND) template at radical prostatectomy (RP). PATIENTS AND METHODS: A total of 485 patients underwent RP and PLND at a referral centre between 2000 and 2008 (historical cohort: classic extended PLND template) and a total of 268 patients between 2010 and 2015 (contemporary cohort: extended PLND template including LNs located along the common iliac vessels and in the fossa of Marcille). Descriptive analyses were used to compare baseline, pathological, complication and functional data between the two cohorts. A logistic regression model was used to assess the template's effect on the probability of detecting LN metastases. RESULTS: Of 80 patients in the historical cohort with pN+ disease, the sole location of metastasis was the external iliac/obturator fossa in 23 (29%), and the internal iliac in 18 (23%), while 39 patients (49%) had metastases in both locations. Of 72 patients in the contemporary cohort with pN+ disease, the sole location of metastasis was the external iliac/obturator fossa in 17 patients (24%), the internal iliac in 24 patients (33%), and the common iliac in one patient (1%), while 30 patients (42%) had metastases in >1 location (including fossa of Marcille in five patients). Among all 46 patients in the contemporary cohort with ≤2 metastases, three had one or both metastases in the common iliac region or the fossa of Marcille. The adjusted probability of detecting LN metastases was higher, but not significantly so, in the contemporary cohort. There were no differences between the two cohorts in complication rates and functional outcomes. CONCLUSION: A more extended template detects LN metastases in the common iliac region and the fossa of Marcille and is not associated with a higher risk of complications; however, the overall probability of detecting LN metastases was not significantly higher.

Nerve-sparing radical cystectomy has a beneficial impact on urinary continence after orthotopic bladder substitution, which becomes even more apparent over time.

OBJECTIVE: To analyse urinary continence in long-term survivors after radical cystectomy (RC) and orthotopic bladder substitution (OBS) according to attempted nerve-sparing (NS) status. PATIENTS AND METHODS: We analysed 180 consecutive patients treated at our department between 1985 and 2007, who underwent RC with OBS, and survived ≥10 years after RC. We stratified patients by attempted NS status and evaluated continence outcomes using descriptive statistics and Cox proportional hazards regression models. A secondary analysis evaluated erectile function as a quality control for attempted NS. RESULTS: The median (interquartile range [IQR]) age at RC was 62 (57-71) years. Of 180 patients, attempted NS status was none in 24 (13%), unilateral in 100 (56%), and bilateral in 56 (31%). After a median (IQR) follow-up of 169 (147-210) months, 160 (89%) patients were continent during daytime and 124 (69%) during night-time. In multivariable analysis, any degree of attempted NS was significantly associated with daytime continence (odds ratio [OR] 2.08, 95% confidence interval [CI] 1.05-4.11; P = 0.04). Correspondingly, any attempted NS was significantly associated with night-time continence (OR 2.51, 95% CI 1.08-5.85; P = 0.03). Recovery of erectile function at 5 years was also significantly associated with attempted NS (P < 0.001). CONCLUSION: Nerve-sparing during RC and OBS was associated with better long-term continence outcomes. This becomes more apparent as the patients age with their OBS. We advocate a NS RC whenever an OBS is considered.

Reproductive organ-sparing cystectomy significantly improves continence in women after orthotopic bladder substitution without affecting oncological outcome.

OBJECTIVES: To compare functional and oncological outcomes of reproductive organ-sparing cystectomy (ROSC) compared with standard cystectomy (SC) in women undergoing orthotopic bladder substitution (OBS). PATIENTS AND METHODS: Between 1995 and 2016, 121 consecutive women undergoing OBS were prospectively included in this single-centre non-randomized clinical follow-up study comprising an ROSC and an SC group. Urinary continence, the need for intermittent self-catheterization (ISC), lateral standing micturition cystourethrogram (MCUG), urethral pressure profile findings, if available, and oncological outcomes were assessed and compared between ROSC and SC. RESULTS: After 12 months, patients who had undergone ROSC with OBS had significantly higher daytime and nighttime continence rates than patients who had undergone SC with OBS (87.5% vs 63.5%; P = 0.027 and 87.5% vs 57.7%; P = 0.008), whereas no significant differences were found between groups in ISC rates (12.5% vs 12.94%; P > 0.99). The degree of attempted nerve-sparing (none, unilateral, bilateral) positively affected continence rates in both groups. No significant differences were found in local recurrence rates (0% vs 9.4%; P = 0.126), 5- and 10-year overall survival rates (80.9% and 80.9% vs 64.9% and 55.7%; P = 0.443) or 5- and 10-year cancer-specific survival rates (84.3% and 84.3% vs 73% and 66.2%; P = 0.431). CONCLUSION: Superior continence rates were found for ROSC with an OBS compared with SC, without a negative impact on oncological outcome. ROSC should, therefore, be offered to women receiving an OBS whenever justifiable.

Impact of intra-operative fluid and noradrenaline administration on early postoperative renal function after cystectomy and urinary diversion: A retrospective observational cohort study.

BACKGROUND: The use of noradrenaline to enable a restrictive approach to intra-operative fluid therapy to avoid salt and water overload has gained increasing acceptance. However, concerns have been raised about the impact of this approach on renal function. OBJECTIVES: To identify risk factors for acute kidney injury (AKI) in patients undergoing cystectomy with urinary diversion and determine whether administration of noradrenaline and intra-operative hydration regimens affect early postoperative renal function. DESIGN: Retrospective observational cohort study. SETTING: University hospital, from 2007 to 2016. PATIENTS: A total of 769 consecutive patients scheduled for cystectomy and urinary diversion. Those with incomplete data and having pre-operative haemodialysis were excluded. MAIN OUTCOME MEASURES: AKI was defined as a serum creatinine increase of more than 50% over 72 postoperative hours. Multiple logistic regression analysis was performed to model the association between risk factors and AKI. RESULTS: Postoperative AKI was diagnosed in 86/769 patients (11.1%). Independent predictors for AKI were the amount of crystalloid administered (odds ratio (OR) 0.79 [95% confidence interval (CI), 0.68 to 0.91], P = 0.002), antihypertensive medication (OR 2.07 [95% CI, 1.25 to 3.43], P = 0.005), pre-operative haemoglobin value (OR 1.02 [95% CI, 1.01 to 1.03], P = 0.010), duration of surgery (OR 1.01 [95% CI, 1.00 to 1.01], P = 0.002), age (OR 1.32 [95% CI, 1.44 to 1.79], P = 0.002) but not the administration of noradrenaline (OR 1.09 [95% CI, 0.94 to 1.21], P = 0.097). Postoperative AKI was associated with longer hospital stay (18 [15 to 22] vs. 16 [15 to 19] days; P = 0.035) and a higher 90-day major postoperative complication rate (41.9 vs. 27.5%; P = 0.002). CONCLUSION: Noradrenaline administration did not increase the risk for AKI. A too restrictive approach to administration of crystalloids was associated with an increased risk for AKI, particularly in older patients, those receiving antihypertensive medication, and those whose surgery was prolonged. As AKI was associated with longer hospital stay and increased postoperative morbidity, these observations should be taken into account to improve outcome when addressing peri-operative fluid management. TRIAL REGISTRATION: Not applicable.

Stenting Prior to Cystectomy is an Independent Risk Factor for Upper Urinary Tract Recurrence.

PURPOSE: Patients with bladder cancer who present with hydronephrosis may require drainage of the affected kidney before receiving further cancer treatment. Drainage can be done by retrograde stenting or percutaneously. However, retrograde stenting carries the risk of tumor cell spillage to the upper urinary tract. The aim of this study was to evaluate whether patients with bladder cancer are at higher risk for upper urinary tract recurrence if retrograde stenting has been performed prior to radical cystectomy. MATERIALS AND METHODS: We retrospectively analyzed the records of 1,005 consecutive patients with bladder cancer who underwent radical cystectomy at our department between January 2000 and June 2016. Negative intraoperative ureteral margins were mandatory for study inclusion. Patients received regular followup according to our institutional protocol, including imaging of the upper urinary tract and urine cytology. RESULTS: Preoperative drainage of the upper urinary tract was performed in 114 of the 1,005 patients (11%), including in 53 (46%) by Double-J® stenting and in 61 (54%) by percutaneous nephrostomy. Recurrence developed in the upper urinary tract in 31 patients (3%) at a median of 17 months after cystectomy, including 7 of 53 (13%) in the Double-J group, 0% in the nephrostomy group and 24 of 891 (3%) in the no drainage group. Multivariate regression analysis revealed a higher risk of upper urinary tract recurrence if patients underwent Double-J stenting (HR 4.54, 95% CI 1.43-14.38, p = 0.01) and preoperative intravesical instillations (HR 2.94, 95% CI 1.40-6.16, p = 0.004). CONCLUSIONS: Patients who undergo Double-J stenting prior to radical cystectomy are at higher risk for upper urinary tract recurrence. If preoperative upper urinary tract drainage is required, percutaneous drainage might be recommended.
