PURPOSE
Lymphovascular invasion (LVI) is an important step in bladder cancer cell dissemination. We aimed to perform a systematic review and meta-analysis of the literature to assess the prognostic value of LVI in radical cystectomy (RC) specimens.
PATIENTS AND METHODS
A systematic review and meta-analysis of the last 10 years was performed using the MEDLINE, EMBASE, and the Cochrane libraries in July 2017. The analyses were performed in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis (PRISMA) statement.
RESULTS
We retrieved 65 studies (including 78,107 patients) evaluating the effect of LVI on oncologic outcomes in patients treated with RC. LVI was reported in 35.4% of patients. LVI was associated with disease recurrence (pooled hazard ratio [HR] = 1.57; 95% CI: 1.45-1.70) and cancer-specific mortality (CSM) (pooled HR = 1.59; 95% CI: 1.48-1.73) in all studies regardless of tumor stage and node status (pT1-4 pN0-2). LVI was associated with recurrence and CSM in patients with node-negative bladder cancer (BC). In patients with node-negative BC, LVI rate increased and was associated with worse oncologic outcome. LVI had a lower but still significant association with disease recurrence and CSM in node-positive BC.
CONCLUSIONS
LVI is a strong prognostic factor of worse prognosis in patients treated with RC for bladder cancer. This association is strongest in node-negative BC, but it is also in node-positive BC. LVI should be part of all pathological reporting and could provide additional information for treatment-decision making regarding adjuvant therapy after RC.

Review
Muscle-invasive bladder cancer poses a significant clinical challenge that necessitates effective therapeutic interventions. Radical cystectomy is a primary treatment option, but a comprehensive understanding of its outcomes is crucial for informed clinical decision-making. This systematic review and meta-analysis aimed to investigate and summarize the outcomes associated with radical cystectomy as a primary treatment for muscle-invasive bladder cancer with a focus on survival rates, complications, and quality of life. A systematic search across databases-PubMed, Google Scholar, and others-covered studies from 2017 onwards. Included were studies reporting survival rates, complications, and quality of life post-radical cystectomy in muscle-invasive bladder cancer patients, including randomized controlled trials, cohort, and observational studies. Multidimensional analysis revealed promising findings regarding the efficacy of radical cystectomy in muscle-invasive bladder cancer. Survival outcomes, including overall survival and disease-specific mortality, have demonstrated significant improvements, particularly in recent randomized controlled trials and cohort studies. Complications associated with the surgical procedure, such as positive surgical margins and lymph node yields, were generally acceptable. Quality of life outcomes post-radical cystectomy exhibited positive trends, although variations were noted in the emotional and social domains. This review underscores radical cystectomy's role in enhancing overall survival and reducing disease-specific mortality in muscle-invasive bladder cancer. Despite reported complications, recent studies support its acceptable risk profile. Detailed examination of various factors contributes to a comprehensive understanding of the procedure. These findings emphasize the importance of individualized treatment approaches in the management of muscle-invasive bladder cancer, considering both oncological efficacy and perioperative outcomes. Radical cystectomy remains fundamental in urological oncology, with ongoing advancements refining its significance.

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.

Comparative Study Meta-Analysis
Prophylactic abdominal or retroperitoneal drain placement in major uro-oncological surgery: a systematic review and meta-analysis of comparative studies on radical prostatectomy, cystectomy and partial nephrectomy.
PURPOSE
To systematically analyze the impact of prophylactic abdominal or retroperitoneal drain placement or omission in uro-oncologic surgery.
METHODS
This systematic review follows the Cochrane recommendations and was conducted in line with the PRISMA and the AMSTAR-II criteria. A comprehensive database search including Medline, Web-of-Science, and CENTRAL was performed based on the PICO criteria. All review steps were done by two independent reviewers. Risk of bias was assessed with the Cochrane tool for randomized trials and the Newcastle-Ottawa Scale.
RESULTS
The search identified 3427 studies of which eleven were eligible for qualitative and ten for quantitative analysis reporting on 3664 patients. Six studies addressed radical prostatectomy (RP), four studies partial nephrectomy (PN) and one study radical cystectomy. For RP a reduction in postoperative complications was found without drainage (odds ratio (OR)[95% confidence interval (CI)]: 0.62[0.44;0.87], p = 0.006), while there were no differences for re-intervention (OR[CI]: 0.72[0.39;1.33], p = 0.300), lymphocele OR[CI]: 0.60[0.22;1.60], p = 0.310), hematoma (OR[CI]: 0.68[0.18;2.53], p = 0.570) or urinary retention (OR[CI]: 0.57[0.26;1.29], p = 0.180). For partial nephrectomy no differences were found for overall complications (OR[CI]: 0.99[0.65;1.51], p = 0.960) or re-intervention (OR[CI]: 1.16[0.31;4.38], p = 0.820). For RC, there were no differences for all parameters. The overall-quality of evidence was assessed as low.
CONCLUSION
The omission of drains can be recommended for standardized RP and PN cases. However, deviations from the standard can still mandate the placement of a drain and remains surgeon preference. For RC, there is little evidence to recommend the omission of drains and future research should focus on this issue.

Meta-Analysis
INTRODUCTION
Radical cystectomy represents the standard of care for localized muscle invasive or high-grade non-muscle invasive BCG unresponsive bladder cancer. Several randomized control trials have been published comparing open (ORC) with robot-assisted radical cystectomy (RARC). We aimed to summarize evidence in this setting with a systematic review and meta-analysis.
EVIDENCE ACQUISITION
All published randomized prospective trials that compared ORC with RARC were retrieved through a systematic search according to PRISMA guidelines. Outcomes investigated were the risks of overall complications, high grade (Clavien-Dindo ≥3) complications, positive surgical margins, the number of lymph nodes removed, estimated blood loss, operative time, length of hospital stay, quality of life, overall survival (OS) and progression-free survival. A random effect model was applied. Subgroup analysis on the basis of the urinary diversion was also performed.
EVIDENCE SYNTHESIS
Seven trials enrolling 974 patients were included. No differences in terms of major oncological and perioperative outcomes between RARC and ORC were observed. However, length of hospital stay was significantly shorter (MD -0.95; 95%CI -1.32, -0.58) and estimated blood loss lower (MD -296.66; 95%CI -462.59, -130.73) for RARC. Operative time was overall shorter for ORC (MD 89.52; 95%CI 55.88, 123.16), however no difference emerged between ORC and RARC with intracorporeal urinary diversion.
CONCLUSIONS
Despite several limitations due to heterogeneity and possible unaddressed confounding in included trials, we concluded that ORC and RARC represent equally valid options for the surgical treatment of patients with advanced bladder cancer.

Meta-Analysis Review
PURPOSE
Even though there isn't enough clinical evidence to demonstrate that robot-assisted radical cystectomy (RARC) is preferable to open radical cystectomy (ORC), RARC has become a widely used alternative. We performed the present study of RARC vs ORC with a focus on oncologic, pathological, perioperative, and complication-related outcomes and health-related quality of life (QOL).
METHODS
We conducted a literature review up to August 2022. The search included PubMed, EMBASE and Cochrane controlled trials register databases. We classified the studies according to version 2 of the Cochrane risk-of-bias tool for randomized trials (RoB 2). The data was assessed by Review Manager 5.4.0.
RESULTS
8 RCTs comparing 1024 patients were analyzed in our study. RARC was related to lower estimated blood loss (weighted mean difference (WMD): -328.2; 95% CI -463.49--192.92; p < 0.00001), lower blood transfusion rates (OR: 0.45; 95% CI 0.32 - 0.65; p < 0.0001) but longer operation time (WMD: 84.21; 95% CI 46.20 -121.72; p < 0.0001). And we found no significant difference in terms of positive surgical margins (P = 0.97), lymph node yield (P = 0.30) and length of stay (P = 0.99). Moreover, no significant difference was found between the two groups in terms of survival outcomes, pathological outcomes, postoperative complication outcomes and health-related QOL.
CONCLUSION
Based on the present evidence, we demonstrated that RARC and ORC have similar cancer control results. RARC is related to less blood loss and lower transfusion rate. We found no difference in postoperative complications and health-related QOL between robotic and open approaches. RARC procedures could be used as an alternate treatment for bladder cancer patients. Additional RCTs with long-term follow-up are needed to validate this observation.

PURPOSE OF REVIEW
The clinical significance of ureteral and urethral recurrence in patients treated with radical cystectomy for bladder cancer is scarce and heterogeneous. The aim of the current review is to summarize the recent literature on incidence, diagnosis and oncologic outcomes of ureteral and urethral recurrences after radical cystectomy.
RECENT FINDINGS
Frozen section analysis (FSA) of ureteral margin had a sensitivity and specificity of 69-77 and 83-96%, respectively. Considering the ureteral margin, the reported sensitivity and specificity were 33-93 and 99-100%, respectively. Transurethral biopsy of the prostatic urethra might help in counseling patients' treatment, although its accuracy and prognostic role is highly questionable. In patients treated with radical cystectomy, recurrence of the urethra or ureteral are rare, occurring approximately in 5% of patients. During the follow-up, urinary cytology and cross-sectional imaging improve the early detection of recurrence in asymptomatic patients, although the majority are diagnosed for symptomatic presentation. Their use should be tailored to the patient's risk of ureteral and/or urethral recurrence. Urethrectomy is indicated in case of singular urethral recurrence, whereas no clear data exists regarding the best management of ureteral recurrence, except surgical removal.
SUMMARY
Intraoperative FSA of ureters and urethra share good specificity but poor sensitivity. Recurrence at urethra and upper tract are rare and discordant data exists regarding survival outcomes. Oncologic surveillance after radical cystectomy with the aim to detect these recurrences should be tailored to the individualized patient's risk.

Review
Radical cystectomy and regional lymph node dissection is the standard treatment for localized muscle-invasive and for high-risk non-muscle-invasive bladder cancer, and represents one of the main surgical urologic procedures. The open surgical approach is still widely adopted, even if in the last two decades efforts have been made in order to evaluate if minimally invasive procedures, either laparoscopic or robot-assisted, might show a benefit compared to the standard technique. Open radical cystectomy is associated with a high complication rate, but data from the laparoscopic and robotic surgical series failed to demonstrate a clear reduction in post-operative complication rates compared to the open surgical series. Laparoscopic and robotic radical cystectomy show a reduction in blood loss, in-hospital stay and transfusion rates but a longer operative time, while open radical cystectomy is typically associated with a shorter operative time but with a longer in-hospital admission and possibly a higher rate of high grade complications.

SUMMARY
The literature highlights the importance of hormonal treatment for symptom relief, reduced surgical complications and postoperative benefits, including a reduction in pain, disease recurrence and improved pregnancy rates. The treatment of endometriosis can be broadly categorized into medical, commonly using hormonal suppression medications and surgical, in which endometriosis tissue is excised or ablated. This review aims to outline current management strategies and examines the relationship between the two treatment modalities.

Review
INTRODUCTION
To identify risk-predictive models for bladder-specific cancer mortality in patients undergoing radical cystectomy and assess their clinical utility and risk of bias.
METHODS
Systematic review (CRD42021224626:PROSPERO) in Medline and EMBASE (from their creation until 31/10/2021) was screened to include articles focused on the development and internal validation of a predictive model of specific cancer mortality in patients undergoing radical cystectomy. CHecklist for critical Appraisal and data extraction for systematic Reviews of prediction Modelling Studies (CHARMS) and Prediction model Risk Of Bias ASsessment Tool (PROBAST) were applied.
RESULTS
Nineteen observational studies were included. The main predictors were sociodemographic variables, such as age (18 studies, 94.7%) and sex (17, 89.5% studies), tumour characteristics (TNM stage (18 studies, 94.7%), histological subtype/grade (15 studies, 78.9%), lymphovascular invasion (10 studies, 52.6%) and treatment with chemotherapy (13 studies, 68.4%). C-index values were presented in 14 studies. The overall risk of bias assessed using PROBAST led to 100% of studies being classified as high risk (the analysis domain was rated to be at high risk of bias in all the studies), and 52.6% showed low applicability. Only 5 studies (26.3%) included an external validation and 2 (10.5%) included a prospective study design.
CONCLUSIONS
Using clinical predictors to assess the risk of bladder-specific cancer mortality is a feasibility alternative. However, the studies showed a high risk of bias and their applicability is uncertain. Studies should improve the conducting and reporting, and subsequent external validation studies should be developed.
