Review
Systematic review comparing uretero-enteric stricture rates between open cystectomy with ileal conduit, robotic cystectomy with extra-corporeal ileal conduit and robotic cystectomy with intra corporeal ileal conduit formation.
Cystectomy is the gold standard treatment for muscle invasive bladder cancer. Robotic cystectomy has become increasingly popular owing to quicker post- operative recovery, less blood loss and less post-operative pain. Urinary diversion is increasingly being performed with an intracorporeal technique. Uretero-enteric strictures (UES) cause significant morbidity for patients. UES for open cystectomy is 3-10%, but the range is much wider (0-25%) for robotic surgery. We aim to perform systematic review for studies comparing all 3 techniques, to assess for ureteric stricture rates. A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement (Page et al. in BMJ 29, 2021). PubMed, Scopus and Embase databases were searched for the period January 2003 to June 2023 inclusive for relevant publications.The primary outcome was to identify ureteric stricture rates for studies comparing open cystectomy and urinary diversion, robotic cystectomy with extracorporeal urinary diversion (ECUD) and robotic cystectomy with intracorporeal urinary diversion (ICUD). Three studies were identified and included 2185 patients in total. The open operation had the lowest stricture rate (9.6%), compared to ECUD (12.4%) and ICUD (15%). ICUD had the longest time to stricture (7.55 months), ECUD (4.85 months) and the open operation (4.75 months). Open operation had the shortest operating time. The Bricker anastomoses was the most popular technique. Open surgery has the lowest rates of UES compared to both robotic operations. There is a learning curve involved with performing robotic cystectomy and urinary diversion, this may need to be considered to decide whether the technique is comparable with open cystectomy UES rates. Further research, including Randomised Control Trials (RCT), needs to be undertaken to determine the best surgical option for patients to minimise risks of UES.

Meta-Analysis Review
BACKGROUND
We aimed to assess the prognostic value of tumor infiltrating lymphocytes (TILs) in patients with bladder cancer (BC) after radical cystectomy (RC).
MATERIALS AND METHODS
We searched Pubmed, Web of Science and Scopus in April 2022 to identify studies assessing the prognostic value of TILs, including a subset of lymphocytes (eg, CD3, CD8, FOXP3), after RC. The endpoints were overall survival and recurrent free survival. Subgroup analyses were performed based on the evaluation method for TILs (ie, CD3, CD8, FOXP3, HE staining).
RESULTS
Overall, 9 studies comprising 1413 patients were included in this meta-analysis. The meta-analysis revealed that elevated expressions of TILs were significantly associated with favorable OS (pooled hazard ratio [HR]: 0.65, 95% confidence interval [CI]: 0.51-0.83) and RFS (pooled HR: 0.48, 95% CI: 0.35-0.64). In subgroup analyses, high CD8+ TILs were also associated with favorable OS (HR: 0.51, 95% CI: 0.33-0.80) and RFS (pooled HR: 0.53, 95% CI: 0.36-0.76). Among 3 studies comprising 146 patients, high intratumoral TILs were significantly associated with favorable OS (pooled HR: 0.34, 95% CI: 0.19-0.60).
CONCLUSION
TILs are useful prognostic markers in patients treated with RC for BC. Although the prognostic value of TILs is varied, depending on the subset and infiltration site, CD8+ TILs and intratumoral TILs are associated with oncologic outcomes. Further studies are warranted to explicate the predictive value of TILs on the response to perioperative systemic therapy to help clinical decision-making in patients with BC.

Review
Endometriosis, as a chronic disorder that is a source of severe pain ailments and infertility, requires a comprehensive therapeutic approach. Sclerotherapy, consisting of the administration of sclerosing agents into the cyst, is a constantly evolving minimally invasive treatment method for this disease. Hence, the main objective of this systematic review was to evaluate the impact of its most often used variant, transvaginal ethanol sclerotherapy, on endometriosis-related symptoms, endometrial cyst recurrence rate, ovarian reserve, assisted reproductive technology (ART) outcomes, and pregnancy outcomes, as well as to assess potential complications resulting from this treatment. This systematic review was undertaken using PubMed, Scopus, Web of Science, and Cochrane Library databases on 24 November 2023. The risk of bias in included studies was assessed with the use of the Newcastle-Ottawa scale (NOS) and the revised Cochrane risk of bias 2.0 tool for randomized controlled trials. From the 1141 records obtained from all databases, 16 studies have been included in this review. The use of ethanol sclerotherapy was characterized by a low rate of post-procedural complications. The recurrence rate of endometrial cysts after the procedure depended on the ethanol instillation time within the cyst. Although ethanol sclerotherapy had negligible influence on ovarian reserves when compared to laparoscopic cystectomy, the effects of both these methods on pregnancy outcomes were comparable. This review identifies that sclerotherapy is safe, provides significant relief of symptoms, and does not impair the reproductive potential of the patients.

Meta-Analysis
Robot-assisted radical cystectomy with intracorporeal urinary diversion: an updated systematic review and meta-analysis of its differential effect on effectiveness and safety.
BACKGROUND
Robot-assisted laparoscopic cystectomy with intracorporeal urinary diversion (iRARC) is increasingly being used in recent years. Whether iRARC offers advantages over open radical cystectomy (ORC) remains controversial. This study aimed to compare the difference of perioperative outcomes, oncological outcomes and complications between iRARC and ORC.
METHODS
The PubMed, Embase, Cochrane Library, Web of Science and CNKI databases were searched in July 2023 according to the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analyses) statement. Studies were identified to be eligible if they compared perioperative outcomes, oncological outcomes and complications in patients who underwent iRARC with ORC.
RESULTS
Twenty-two studies involving 7020 patients were included. Compared to ORC, iRARC was superior for estimated blood loss [estimated blood loss (EBL) weighted mean difference (WMD): -555.52; 95% CI, -681.64 to -429.39; P <0.001], blood transfusion rate [odds ratio (OR): 0.16; 95% CI, 0.09-0.28; P <0.001], length of hospital stay [length of hospital stay (LOS) WMD: -2.05; 95% CI, -2.93 to -1.17; P <0.001], Clavien-Dindo grades ≥III complication rate [30 days: OR: 0.57; 95% CI 0.44-0.75; P <0.001; 90 days: OR: 0.71; 95% CI 0.60-0.84; P <0.001], and positive surgical margin [positive surgical margin (PSM) OR: 0.65; 95% CI 0.49-0.85; P =0.002]. However, iRARC had a longer operative time [operative time (OT) WMD: 68.54; 95% CI 47.41-89.67; P <0.001] and a higher rate of ureteroenteric stricture [ureteroenteric stricture (UES) OR: 1.56; 95% CI 1.16-2.11; P =0.003]. Time to flatus, time to bowel, time to regular diet, readmission rate, Clavien-Dindo grades less than III complication rate for iRARC were similar to that for ORC. Interestingly, the results of subgroup analysis revealed no difference in EBL between iRARC and ORC when the diversion type was neobladder. When the ileal conduit was selected as the diversion type, the LOS was similar in both procedures.
CONCLUSION
Robot-assisted laparoscopic cystectomy with intracorporeal urinary diversion appears to be superior to open radical cystectomy in terms of effectiveness and safety. However, attention should be paid to the occurrence of ureteroenteric stricture during follow-up.

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.

Review
INTRODUCTION
Ureteroenteric stricture (UES) is the leading cause of renal function deterioration after radical cystectomy (RC) and urinary diversion (UD). The aim of the present review is to summarize studies that discussed the risk factors associated with UES development. Identifying the responsible factors is of importance to help surgeons to modify their treatment or follow-up strategies to reduce this serious complication.
MATERIALS AND METHODS
A comprehensive search of the literature using the PubMed database was conducted. The target of the search was only studies that primarily aimed to identify risk factors of UES after RC and UD. References of searched papers were also checked for potential inclusion.
RESULTS
The search originally yielded a total of 1357 articles, of which only 15 met our inclusion criteria, comprising 13, 481 patients. All the studies were observational, and retrospective published between 2013 and 2022. The natural history of UES and the reported risk factors varied widely across the studies. In 13 studies, a significant association between some risk factors and UES development was demonstrated. High body mass index (BMI) was the most frequently reported stricture risk factor, followed by perioperative urinary tract infection (UTI), robotic-assisted radical cystectomy (RARC), occurrence of post-operative Clavian grade ≥ 3 complications and urinary leakage. Otherwise, many other risk factors were reported only once.
CONCLUSION
The literature is still lacking well-designed prospective studies investigating predisposing factors of UES. The available data suggest that the high BMI, RARC and complicated postoperative course are the main risk factors for stricture formation.

BJUI Compass Jan 2024To characterise cases of spontaneous rupture of the urinary bladder in the context of bladder cancer. (Review)
Review
OBJECTIVES
To characterise cases of spontaneous rupture of the urinary bladder in the context of bladder cancer.
METHODS
A systematic review was performed to characterise cases of spontaneous bladder rupture in patients with bladder cancer. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) system was utilised, with databases being searched for relevant cases. Patient characteristics were extracted, including age, sex, presenting signs and symptoms, management modalities, tumour histology and mortality.
RESULTS
Thirty cases were included. Seventeen (57%) were male, and the median age of presentation was 59. Abdominal pain and peritonism were the most common presenting symptoms, in 80% and 60% of patients, respectively. Most patients ( = 16, 53%) had urothelial cell carcinoma. Nine patients (30%) died during their initial hospitalisation.
CONCLUSION
Spontaneous bladder perforation in the context of bladder cancer is a rare cause of acute abdomen. The diagnosis is associated with high mortality, highlighting the aggressive nature of the malignancies that cause spontaneous bladder rupture. This raises important questions about the role of emergency cystectomy, the timing of systemic therapy and the appropriate involvement of palliative care.

BACKGROUND
Ovarian endometriomas, resulting from the invasion of endometriosis into ovarian tissue, can significantly affect ovarian reserve, potentially leading to infertility. When conservative treatments fail, it may further aggravate ovarian reserve decline by invading the ovarian cortex and, in severe cases, result in premature ovarian failure and infertility.
OBJECTIVE
This study aimed to investigate the impact of various hemostasis methods on ovarian reserve function in cases of laparoscopic cystectomy for ovarian endometriomas.
METHODS
We conducted a systematic review and meta-analysis to assess the effects of different hemostasis techniques used during laparoscopic cystectomy for ovarian endometriomas. A comprehensive analysis of relevant literature was performed, focusing on the impact of bipolar electrocoagulation, ultrasonic scalpel, and suture hemostasis on ovarian reserve function. The evaluation criteria included Anti-Müllerian hormone levels and antral follicle counts.
RESULTS
Our analysis revealed significant variations in the impact of hemostasis methods on ovarian reserve function. While all methods aimed to stop bleeding during surgery, the thermal damage to surrounding tissues differed. Bipolar electrocoagulation, ultrasonic scalpel, and suture hemostasis showed varying effects on ovarian reserve, with implications for post-operative fertility.
CONCLUSIONS
The choice of the hemostasis method in laparoscopic cystectomy for ovarian endometriomas has a crucial influence on ovarian reserve function. Our findings emphasize the need to consider the potential consequences of thermal damage when selecting a hemostasis technique. Clinicians should weigh the benefits and risks of each method to protect ovarian reserve function effectively. This study offers valuable insights for guiding clinical practice, ensuring optimal outcomes for patients facing endometrioma-related fertility challenges.

Meta-Analysis
BACKGROUND
One of the most complex surgeries including radical cystectomy (RC) has a high rate of morbidity. The standard approach for the muscle-invasive bladder is conventional transperitoneal radical cystectomy. However, the procedure is associated with significant morbidities like ileus, urinary leak, bleeding, and infection. The aim of this study is to compare the transperitoneal RC approach with the extraperitoneal RC approach in the treatment of bladder cancer patients. The outcomes of this study are Operative time, Estimated Blood Loss, Hospital Stay, Post-Operative Ileus, Infection, and Major Complication (Clavien-Dindo Grade 3-5).
METHODS
PubMed, Cochrane Library, and Science Direct were systematically searched for different publications related to the meta-analysis. Keywords used for searching were Radical Cystectomy AND Extraperitoneal AND Transperitoneal up until 31st August 2022. The studies were screened for our eligibility criteria. Demographic parameters, perioperative variables, and postoperative complications were recorded and analyzed. The Newcastle-Ottawa Scale was used to evaluate the risk of bias in each study. The Review Manager (RevMan) software version 5.4.1 was used for statistical analysis.
RESULTS
Eight studies (3 laparoscopic and 5 open methods) involving 1207 subjects (588 patients using the extraperitoneal approach and 619 using the transperitoneal approach) were included. The incidence of postoperative ileus is significantly lower after the extraperitoneal approach compared to the transperitoneal approach (p < 0.00001). The two techniques did not differ in operative time, estimated blood loss, duration of hospital stay, total infection, and major complication events.
CONCLUSION
This meta-analysis shows that extraperitoneal radical cystectomy benefits in terms of reduced postoperative ileus.
