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.

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.

PURPOSE OF REVIEW
This article aims to comprehensively review and critique the existing literature on the role of metastatic-directed therapy in patients with metastatic bladder cancer, particularly in oligometastatic disease state.
RECENT FINDINGS
The role of metastasectomy in metastatic bladder cancer is still controversial. Several studies have demonstrated improved outcomes, particularly in a highly selected patients with small metastatic lesions or with lung or brain metastases, whereas others show no significant survival benefit. Combining metastasectomy with systemic therapies, such as immunotherapy and chemotherapy, has also shown benefits. Metastasis-directed radiotherapy is evolving as a potentially effective approach with minimal toxicity in achieving local control and improving survival, particularly in patients with oligometastatic disease. The evidence regarding the impact of several factors such as performance status, metastatic burden, and the presence of visceral metastases on outcomes is mixed. Concurrent treatment with systemic therapy may potentiate the effectiveness of metastasis-directed therapy.
SUMMARY
In patients with metastatic deposits amenable to surgical resection, metastasectomy stands as a promising avenue. Metastatic-directed radiotherapy has demonstrated local control and improved survival in the evolving landscape of oligometastatic bladder cancer management. Further, well designed multicenter prospective studies are needed to support these findings and better understand the synergy between radiotherapy and systemic treatments, especially immunotherapy.

Meta-Analysis Review
Radical cystectomy (RC) is the gold standard treatment for patients with organ-confined bladder cancer. However, despite the success of this treatment, many men who undergo orthotopic neobladder substitution develop significant erectile dysfunction and urinary symptoms, including daytime and nighttime urinary incontinence. Prostate-capsule-sparing radical cystectomy (PCS-RC) with orthotopic neobladder (ONB) has been described in the literature as a surgical technique to improve functional outcomes in appropriately selected patients. We performed a systematic review and meta-analysis of manuscripts on PCS-RC with ONB published after 2000. We included retrospective and prospective studies with more than 25 patients and compared PCS-RC with nerve-sparing or conventional RC. Studies in which the entire prostate was spared (including the transitional zone) were excluded. Comparative studies were analyzed to assess rates of daytime continence, nighttime continence, and satisfactory erectile function in patients undergoing PCS-RC compared with those undergoing conventional RC. Fourteen reports were included in the final review. Our data identify high rates of daytime (83%-97%) and nighttime continence (60%-80%) in patients undergoing PCS-RC with ONB. In comparative studies, meta-analysis results demonstrate no difference in daytime continence (RR:1.12; 95% CI: 0.72-1.73) in those undergoing PCS-RC compared to those undergoing conventional RC. Similarly, nighttime continence was similar between the 2 groups (RR:1.85; 95% CI: 0.57-6.00. Erectile function was improved in those undergoing PCS-RC (RR 5.35; 95% CI: 1.82-15.74) in the PCS-RC series. Bladder cancer margin positivity and recurrence rates were similar to those reported in the literature with conventional RC with an average weighted follow-up of 52.2 months. While several studies utilized different prostate cancer (CaP) screening techniques, the rates of CaP were low (incidence 0.02; 95% CI:0.01-0.04), and oncologic outcomes were similar to standard RC. PCS-RC is associated with improved nighttime continence and erectile function compared to conventional RC techniques. Further work is needed to standardize CaP screening before surgery, but the data suggest low rates of CaP with similar oncologic outcomes when compared to RC.

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.

Comparative Study
One of the most common cancers of the urinary tract is bladder tumors. Bladder cancers are divided into two groups: non-muscle-invasive bladder cancer (NMIBC) and muscle-invasive bladder cancer. (1) Trans-Peritoneal Radical Cystectomy (RC) with pelvic lymphadenectomy is the standard technique in muscle invasive and high risk non-muscle invasive bladder cancer (2). and Urologist around the world are more familiar with trans-peritoneal technique. In some articles extra-peritoneal Radical Cystectomy (RC) implied as an decreased postoperative complications techniques. In this letter we want to compare these two techniques and find out the pros and cons of these techniques.

BACKGROUND
The application of pelvic organ preserving-radical cystectomy (POPRC) in female patients with bladder cancer has attracted more and more attention in recent years. In the current study, the authors aim to compare the long-term oncological outcomes of POPRC versus standard radical cystectomy (SRC) in a large multicenter retrospective cohort.
PATIENTS AND METHODS
Data on female patients with bladder cancer who underwent POPRC or SRC in January 2006 and April 2018 were included from three Chinese urological centers. The primary outcome was overall survival (OS). Secondary outcomes were cancer-specific survival and recurrence-free survival. To decrease the effect of unmeasured confounders associated with treatment selection, 1:1 propensity score matching was performed.
RESULTS
Among the 273 enrolled patients, 158 underwent POPRC (57.9%), and 115 underwent SRC (42.1%). The median follow-up time was 38.6 (15.9-62.5) months. After propensity score matching, each cohort included 99 matched patients. The OS ( P =0.940), cancer-specific survival ( P =0.957), and recurrence-free survival ( P =0.476) did not differ significantly from the two matched cohorts. Subgroup analysis confirmed that the OS was similar between the patients treated with POPRC and SRC across all subgroups examined (all P > 0.05). In multivariable analysis, the surgical method (SRC vs. POPRC) was not an independent risk factor for OS (Hazard ratio 0.874, 95% CI 0.592-1.290; P =0.498).
CONCLUSIONS
The results showed that no significant difference in long-term survival was determined between female patients undergoing SRC and those undergoing POPRC.

Scandinavian Journal of Urology Sep 2023The aim of this study was to investigate health-related quality of life (HRQoL) before and 1 year after radical cystectomy in relation to age and gender.
OBJECTIVE
The aim of this study was to investigate health-related quality of life (HRQoL) before and 1 year after radical cystectomy in relation to age and gender.
METHODS
This prospective study involves 112 men and 40 women with bladder cancer treated with radical cystectomy between 2015 and 2018. HRQoL was assessed preoperatively and 1 year post-surgery through Functional Assessment of Cancer Therapy Scale - General (FACT-G) and Functional Assessment of Cancer Therapy Scale - Vanderbilt Cystectomy Index (FACT-VCI) questionnaires. The median age of the 152 patients was 71.5 years.
RESULTS
Preoperatively, emotional and functional well-being were negatively affected. Physical, emotional and functional well-being presented higher values 1 year after surgery compared to before radical cystectomy, that is, better HRQoL. Social well-being showed a reduction, especially regarding closeness to partner and support from family. Men and women were equally satisfied with their sex life before radical cystectomy, but less so 1 year after, where men were less satisfied compared to women. Additionally, one out of five patients reported that they had to limit their physical activities, were afraid of being far from a toilet and were dissatisfied with their body appearance after surgery.
CONCLUSIONS
Recovery regarding HRQoL was ongoing 1 year after radical cystectomy. Patients recovered in three out of four dimensions of HRQoL, but social well-being was still negatively affected 1 year after treatment. Sexual function after radical cystectomy was exceedingly limited for both men and women. An individual sexual rehabilitation plan involving the couple with special intention to encourage intimacy, might not only improve sexual life but also have a positive effect on social well-being as a consequence.

BACKGROUND
To explore a method of constructing an orthotopic ileal neobladder (ONB) in the Y-pouch configuration. We describe the steps followed to create the Y-pouch ileal orthotopic neobladder (ONB) and compared the perioperative, functional, and urodynamics outcomes with the Studer neobladder technique.
METHODS
A retrospective cohort study of 90 bladder cancer patients, who received open radical cystectomy with the ONB performed at a hospital from June 2009 to May 2020. These patients were divided into two groups-the Y-pouch and the Studer neobladder groups. Perioperative, functional outcome, complication, renal function data outcomes, and pressure-volume study were used to evaluate the treatment outcomes after a radical cystectomy.
RESULTS
Ninety patients (54 Studer and 36 Y-pouch neobladder) were enrolled. The median patient age was 62.6 (± 11) years. The mean operative time for the Studer technique was 290 (242.5-350) min, and the Y-pouch technique was 300 (271.2-335) min) (p = 0.826). At 30 days postoperatively, the Clavien-Dindo classification of surgical complications revealed grade-2 urinary infections in two patients (5.6%) and six patients (11.1%) for the Y-pouch and Studer techniques, respectively. Intermediate complications (30-90 days) were reported in 4 (11.1%) and 18 patients (44.4%) in the Y-pouch and the Studer techniques, respectively (p = 0.062). In the urodynamics study (UDS), the Y-pouch group had a mean postvoid residual volume of 20 mL and Studer of 40 ml (p = 0.06). A mean capacity of 462 (380-600) mL compares to the Studer neobladder group with 495 (400-628) mL. The average mean compliance of the Studer group was 35.5 (28-52) ml/cm HO and 33 (30-43) ml/cm HO for Y pouch, and most patients had > 30 ml/cm HO compliance (80/90 patients).
CONCLUSIONS
The Y-pouch neobladder technique in an RC with an orthotopic neobladder provides perioperative and functional outcomes compared to those of the Studer orthotopic neobladder resulting in similar intermediate-term. Therefore, the Y-pouch ileal neobladder is both feasible and safe to be used as a standard neobladder technique for urinary diversion in patients with bladder cancer undergoing radical cystectomy and needs confirmation with long-term results.
