Meta-Analysis Review
CONTEXT
The question of the ability of frozen section analysis (FSA) to accurately detect malignant pathology intraoperatively has been discussed for many decades.
OBJECTIVE
We aimed to conduct a systematic review and meta-analysis assessing the diagnostic estimates of FSA of the urethral and ureteral margins in patients treated with radical cystectomy (RC) for bladder cancer (BCa).
EVIDENCE ACQUISITION
The MEDLINE and EMBASE databases were searched in February 2021 for studies analyzing the association between FSA and the final urethral and ureteral margin status in patients treated with RC for BCa. The primary endpoint was the value of pathologic detection of urethral and ureteral malignant involvement with FSA during RC compared with the final margin status. We included studies that provided true positive, true negative, false positive, and false negative values for FSA, which allowed us to calculate the diagnostic estimates.
EVIDENCE SYNTHESIS
Fourteen studies, comprising 8208 patients, were included in the quantitative synthesis. Forest plots revealed that the pooled sensitivity and specificity for FSA of urethral margins during RC were 0.83 (95% confidence interval [CI] 0.38-0.97) and 0.95 (95% CI 0.91-0.97), respectively. While for the FSA of ureteral margins, the pooled sensitivity and specificity were 0.77 (95% CI 0.67-0.84) and 0.97 (95% CI 0.95-0.98), respectively. Calculated diagnostic odds ratios indicated high FSA effectiveness, and patients with a positive urethral or ureteral margin at final pathology are over 100 times more likely to have positive FSA than patients without margin involvement at final pathology. Area under the curves of 96.6% and 96.7% were reached for FSA detection of urethral and ureteral tumor involvement, respectively.
CONCLUSIONS
Intraoperative FSA demonstrated high diagnostic performance in detecting both urethral and ureteral malignant involvement at the time of RC for BCa. FSA of both urethral and ureteral margins during RC is accurate enough to be of great value in the routine management of BCa patients treated with RC. While its specificity was great to guide intraoperative decision-making, its sensitivity remains suboptimal yet.
PATIENT SUMMARY
We believe that the frozen section analysis of both urethral and ureteral margins during radical cystectomy should be considered more often in urologic practice, until quality of life-based cost-effectiveness studies can identify patients within each institution who are unlikely to benefit from it.

Review
INTRODUCTION
Enhanced recovery after surgery (ERAS) protocols aim to optimize patient recovery after major surgery. Our study was to examine the evidence of the effectiveness of interventions designed to improve patient outcomes after radical cystectomy.
DESIGN
Systematic review and meta-analysis.
DATA SOURCES
PubMed, Medline, Embase, Cochrane from January 2005 to January 2021 without language restrictions.
ELIGIBILITY CRITERIA
Randomized and non-randomized controlled studies implementing ERAS measuring its interventions on rates of postoperative complications, 30-day readmission, length of stay (LOS) and bowel function after radical cystectomy.
DATA EXTRACTION AND SYNTHESIS
Two members of the investigating team independently selected studies and evaluated bias using the Cochrane collaboration tool. Meta-analysis of all comparative studies used inversed-weighted, fixed- effects models and random effects models to pool results. Publication bias was graphically assessed using contour-enhanced funnel plots and the Egger's test of funnel plot symmetry.
RESULTS
Fifteen studies were included in our meta-analysis; we observed that ERAS decreased the time for the first bowel movement (standardized mean difference [SMD]: -1.30, 95% CI -1.90 to -0.70, P<0.00001) and shortened the length of stay (LOS) ([SMD]: -0.49, 95% CI -0.77 to -0.20, (P < 0.00001)); however, 30-day readmission (risk ratio [RR]: 0.97,95% [CI] 0.73 to 1.28, P=0.52) and the overall postoperative complication rate (risk ratio [RR]: 0.98,95% confidence interval [CI]: 0.88 to 1.09, P= 0.41) showed no significant difference.

Review
INTRODUCTION
Urothelial carcinoma can arise from the urinary bladder or from the upper urinary tract. In some instances, urinary bladder cancer (UBC) and upper tract urothelial carcinoma (UTUC) can be concurrently diagnosed, necessitating a combined radical cystectomy (RC) with radical nephroureterectomy (RNU). A systematic review was done on the combined procedure exploring outcomes and indications, in addition to a comparative analysis between the combined procedure and cystectomy alone.
METHODS
For the systematic review, three databases (Embase, PubMed, and Cochrane) were queried, selecting only studies that included intraoperative and perioperative data. For the comparative analysis, using the NSQIP database, CPT codes for RC and RNU were used to identify two cohorts, one with RC and RNU and one with RC alone. A descriptive analysis was performed on all preoperative variables, and propensity score matching (PSM) was performed. Postoperative events were then compared between the two matched cohorts.
RESULTS
For the systematic review, 28 relevant articles were included amounting to 947 patients who underwent the combined procedure. The most common indication was synchronous multifocal disease, the most common approach was open surgery, and the most common diversion technique was using an ileal conduit. Almost 28% of patients required blood transfusion and remained in the hospital for an average of 13 days. The most common postoperative complication was prolonged paralytic ileus. For the comparative analysis, 11,759 patients were included of which 97.5% underwent RC only and 2.5% underwent the combined procedure. After PSM, the cohort that had undergone the combined procedure showed an increased risk of renal injury, increased readmission rates, and increased reoperation rates. Whereas the cohort that had undergone RC only showed an increased risk of deep venous thrombosis (DVT), sepsis, or septic shock.
CONCLUSION
A combined RC and RNU is a treatment option for concurrent UCB and UTUC that should be cautiously utilized as it is associated with high morbidity and mortality. Patient selection, discussion of the risks and benefits of the procedure, and explanation of the available treatment options remain the most important pillars in managing patients with this complex disease.

Review
INTRODUCTION
Muscle-invasive bladder cancer (MIBC) is associated with high recurrence and mortality rates. The role of radiotherapy as an adjunct to radical cystectomy is not well-defined. We sought to evaluate the efficacy and safety of radiotherapy preoperatively or postoperatively for patients with MIBC receiving cystectomy compared to cystectomy alone. The primary outcome was overall survival. The secondary outcome was adverse effects.
METHODS
MEDLINE, EMBASE, and CENTRAL were searched on August 30, 2016 for randomized controlled trials (RCTs) of patients undergoing cystectomy for bladder cancer. A control group receiving cystectomy alone and an intervention group with radiotherapy and cystectomy were required. The Jadad score was used to assess for bias. Fifteen studies representing 10 RCTs met eligibility criteria.
RESULTS
A total of 996 patients were randomized in seven trials included in a meta-analysis of neoadjuvant radiotherapy. Insufficient data were available to complete a pooled analysis for adjuvant radiotherapy. There was a non-statistically significant improvement in overall survival for patients who received neo-adjuvant radiotherapy and cystectomy. At three years and five years, the odds ratios were 1.23 (95% confidence interval [CI] 0.72-2.09) and 1.26 (95% CI 0.76-2.09), respectively, in favour of neoadjuvant radiotherapy. Subgroup analyses including higher doses of radiotherapy showed greater effect on survival.
CONCLUSIONS
These data suggest that radiotherapy prior to cystectomy may improve overall survival. This review was limited by old studies, heterogeneous patient populations, and radiotherapy treatment techniques that may not meet current standards. There is a need for current RCTs to further evaluate this effect.

Meta-Analysis
OBJECTIVE
To investigate whether cystectomy or ablation for endometrioma has less impact on ovarian reserve as evaluated by antral follicle count (AFC) and antimüllerian hormone (AMH) levels.
DESIGN
Systematic review and meta-analysis.
SETTING
Not applicable.
PATIENT(S)
Patients with endometriomas undergoing cystectomy or ablation.
INTERVENTION(S)
All prospective studies comparing cystectomy with ablation for endometrioma in the PubMed, EMBASE, MEDLINE and Web of Science until April 3, 2022 were retrieved and reviewed. Medical treatment used as adjuvant therapy for the surgery was excluded. Two authors assessed eligibility and risk of bias independently. The statistical data were pooled using the Review Manager software.
MAIN OUTCOME MEASURE(S)
The changes of AMH levels and AFC values in cystectomy group and ablation group, including intergroup comparisons and intragroup comparisons.
RESULT(S)
Four randomized clinical trials and 2 prospective cohort studies were eligible for the meta-analysis, with a total of 294 patients. In the intergroup comparisons, preoperative AFC values were similar with low heterogeneity, but postoperative AFC values were significantly lower in cystectomy than ablation (mean differences [MD], -1.33; 95% credible interval, -2.15 to -0.51; I = 57%). In the intragroup comparisons of AFC values, sensitivity analyses showed a significant decrease in cystectomy (MD, -1.93; 95% credible interval, -2.40 to -1.45; I = 0%) at 6-month follow-up, compared with no reduction in ablation. The intragroup comparisons of AMH levels supported negative effects on ovarian reserve of both cystectomy (MD, -1.26; 95% credible interval, -1.64 to -0.88; I = 45%) and ablation (MD, -0.70; 95% credible interval, -1.07 to -0.32; I = 0%).
CONCLUSION(S)
Both ablation and cystectomy have significantly detrimental effects on ovarian reserve as evaluated by AMH, but the ablation causes relatively less damage to ovarian reserve as appraised by AFC.

International Journal of Surgery... Oct 2021To systematically review studies comparing the perioperative outcomes of intracorporeal robot-assisted radical cystectomy (iRARC) and open radical cystectomy (ORC). (Meta-Analysis)
Meta-Analysis Review
PURPOSE
To systematically review studies comparing the perioperative outcomes of intracorporeal robot-assisted radical cystectomy (iRARC) and open radical cystectomy (ORC).
METHODS
Systematic searches of PubMed, Web of Science and the Cochrane Library were performed in June 2020. Studies with data comparing iRARC and ORC were included in our review, and a pooled meta-analysis was completed.
RESULTS
In total, 8 studies (7 prospective studies, 1 retrospective study) comparing 1193 patients were included for our review and meta-analysis. Compared with ORC, iRARC demonstrated lower estimated blood loss (weighted mean difference (WMD): -449.25; 95% CI -566.47 - -332.03; p < 0.01), lower blood transfusion rates (OR: 0.31; 95% CI 0.22 - 0.46; p < 0.01), and lower postoperative complication rates with Clavien-Dindo grades III-IV (30 days: OR: 0.65; 95% CI 0.47 - 0.90; p = 0.01; 90 days: OR: 0.72; 95% CI 0.53 - 0.98; p = 0.04), but a longer operative time (WMD: 78.82; 95% CI 52.77 - 104.87; P < 0.01). Furthermore, there was no significant difference between iRARC and ORC in terms of postoperative complication rates with Clavien-Dindo grades Ⅰ-Ⅱ (30 days: OR: 0.71; 95% CI 0.36 - 1.40; p = 0.32; 90 days: OR: 0.98; 95% CI 0.74 - 1.30; p = 0.89), length of stay (WMD: -1.18; 95% CI -3.33 - -2.07; p = 0.06) and positive surgical margins (OR: 0.78; 95% CI 0.0.45 - 1.36; p = 0.38).
CONCLUSION
iRARC was associated with a significantly lower estimated blood loss and a lower blood transfusion rate and major postoperative complication rate than ORC.

OBJECTIVE
To study short-term (<90 days) morbidity and mortality following radical cystectomy (RC) for bladder cancer and identify modifiable risk factors associated with these.
DESIGN
Systematic review.
METHODS
The systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. PubMed and EMBASE were searched for relevant papers on 11 June 2019 and rerun on 27 May 2020. Studies reporting complications, reoperations, length of stay and mortality within 90 days were included. Studies were reviewed according to criteria from the Oxford Centre for Evidence-Based Medicine and the quality of evidence was assessed using the Newcastle-Ottawa Scale.
RESULTS
The search retrieved 1957 articles. Sixty-six articles were included. The quality of evidence was poor to good. Most studies were retrospective, and no randomised clinical trials were identified. Of included studies a median of 6 Martin criteria for reporting complications after surgery were fulfilled. The Clavien-Dindo classification for grading complications was most frequently used. The weighted overall complication rate after RC was 34.9% (range 28.8-68.8) for in-house complications, 39.0% (range 27.3-80.0) for 30-day complications and 58.5% (range 36.1-80.5) for 90-day complications. The most common types of complications reported were gastrointestinal (29.0%) and infectious (26.4%). The weighted mortality rate was 2.4% (range 0.9-4.7) for in-house mortality, 2.1% (0.0-3.7) for 30-day mortality and 4.7% (range 0.0-7.0) for 90-day mortality. Age and comorbidity were identified as the best predictors for complications following RC.
CONCLUSION
Short-term morbidity and mortality are high following RC. Reporting of complications is heterogeneous and the quality of evidence is generally low. There is a continuous need for randomised studies to address any intervention that can reduce morbidity and mortality following RC.

Review
This study aims to conduct a systematic review of full economic analyses of robotic-assisted surgery (RAS) in adults' thoracic and abdominopelvic indications. Authors used Medline, EMBASE, and PubMed to conduct a systematic review following the preferred reporting items for systematic reviews and meta-analyses (PRISMA) 2020 guidelines. Fully published economic articles in English were included. Methodology and reporting quality were assessed using standardized tools. Majority of studies (28/33) were on oncology procedures. Radical prostatectomy was the most reported procedure (16/33). Twenty-eight studies used quality-adjusted life years, and five used complication rates as outcomes. Nine used primary and 24 studies used secondary data. All studies used modeling. In 81% of studies (27/33), RAS was cost-effective or potentially cost-effective compared to comparator procedures, including radical prostatectomy, nephrectomy, and cystectomy. Societal perspective, longer-term time-horizon, and larger volumes favored RAS. Cost-drivers were length of stay and equipment cost. From societal and payer perspectives, robotic-assisted surgery is a cost-effective strategy for thoracic and abdominopelvic procedures.Clinical trial registration This study is a systematic review with no intervention, not a clinical trial.

Review
CONTEXT
Although open radical cystectomy (ORC) is still the standard approach, laparoscopic radical cystectomy (LRC) and robot-assisted radical cystectomy (RARC) are increasingly performed.
OBJECTIVE
To report on a systematic literature review and cumulative analysis of pathologic, oncologic, and functional outcomes of RARC in comparison with ORC and LRC.
EVIDENCE ACQUISITION
Medline, Scopus, and Web of Science databases were searched using a free-text protocol including the terms robot-assisted radical cystectomy or da Vinci radical cystectomy or robot* radical cystectomy. RARC case series and studies comparing RARC with either ORC or LRC were collected. A cumulative analysis was conducted.
EVIDENCE SYNTHESIS
The searches retrieved 105 papers, 87 of which reported on pathologic, oncologic, or functional outcomes. Most series were retrospective and had small case numbers, short follow-up, and potential patient selection bias. The lymph node yield during lymph node dissection was 19 (range: 3-55), with half of the series following an extended template (yield range: 11-55). The lymph node-positive rate was 22%. The performance of lymphadenectomy was correlated with surgeon and institutional volume. Cumulative analyses showed no significant difference in lymph node yield between RARC and ORC. Positive surgical margin (PSM) rates were 5.6% (1-1.5% in pT2 disease and 0-25% in pT3 and higher disease). PSM rates did not appear to decrease with sequential case numbers. Cumulative analyses showed no significant difference in rates of surgical margins between RARC and ORC or RARC and LRC. Neoadjuvant chemotherapy use ranged from 0% to 31%, with adjuvant chemotherapy used in 4-29% of patients. Only six series reported a mean follow-up of >36 mo. Three-year disease-free survival (DFS), cancer-specific survival (CSS), and overall survival (OS) rates were 67-76%, 68-83%, and 61-80%, respectively. The 5-yr DFS, CSS, and OS rates were 53-74%, 66-80%, and 39-66%, respectively. Similar to ORC, disease of higher pathologic stage or evidence of lymph node involvement was associated with worse survival. Very limited data were available with respect to functional outcomes. The 12-mo continence rates with continent diversion were 83-100% in men for daytime continence and 66-76% for nighttime continence. In one series, potency was recovered in 63% of patients who were evaluable at 12 mo.
CONCLUSIONS
Oncologic and functional data from RARC remain immature, and longer-term prospective studies are needed. Cumulative analyses demonstrated that lymph node yields and PSM rates were similar between RARC and ORC. Conclusive long-term survival outcomes for RARC were limited, although oncologic outcomes up to 5 yr were similar to those reported for ORC.
PATIENT SUMMARY
Although open radical cystectomy (RC) is still regarded as the standard treatment for muscle-invasive bladder cancer, laparoscopic and robot-assisted RCs are becoming more popular. Templates of lymph node dissection, lymph node yields, and positive surgical margin rates are acceptable with robot-assisted RC. Although definitive comparisons with open RC with respect to oncologic or functional outcomes are lacking, early results appear comparable.

Review
CONTEXT
Patients undergoing radical cystectomy frequently suffer from infectious complications, including urinary tract infections (UTIs) and surgical site infections (SSIs) leading to emergency department visits, hospital readmission, and added cost.
OBJECTIVE
To summarize the literature regarding perioperative antibiotic prophylaxis, ureteric stent usage, and prevalence of infectious complications after cystectomy.
EVIDENCE ACQUISITION
A systematic review of PubMed/Medline, EMBASE, Cochrane Library, and reference lists was conducted.
EVIDENCE SYNTHESIS
We identified 20 reports including a total of 55 306 patients. The median rates of any infection, UTIs, SSIs, and bacteremia were 40%, 20%, 11%, and 6%, respectively. Perioperative antibiotic prophylaxis differed substantially between reports. Perioperative antibiotics were used only during surgery in one study but were continued over several days after surgery in all other studies. Empirical use of antibiotics for 1-3 d after surgery was described in 12 studies, 3-10 d in two studies, and >10 d in four studies. Time to stent removal ranged from 4 to 25 d after cystectomy. Prophylactic antibiotics were used before stent removal in nine of 20 studies; two of these studies used targeted antibiotics based on urine cultures from the ureteric stents, and the other seven studies used a single shot or 2 d of empirical antibiotics. Studies with any prophylactic antibiotic before stent removal found a lower median percentage of positive blood cultures after stent removal than studies without prophylactic antibiotics before stent removal (2% vs 9%).
CONCLUSIONS
We confirmed a high proportion of infectious complications after cystectomy, and a heterogeneous pattern of choice and duration of antibiotics during and after surgery or stent removal. These findings highlight a need for further studies and support quality prospective trials.
PATIENT SUMMARY
In this review, we observed wide variability in the use of antibiotics before or after surgical removal of the bladder.
