Fistulas arising between ureters and iliac arteries (UAF) are rare pathological events and frequently require emergency treatment, as they are associated with massive haematuria and haemorrhagic shock. The medical history plays a key role in the diagnostic and therapeutic process, as it allows to include UAF among the differential diagnoses of gross haematuria. The emergency treatments of fistulas arising between the urinary system and the vascular system include the open repairing surgery or the endovascular grafting, the latter generally better tolerated by patients suffering from multiple comorbidities or not eligible for traditional surgery. Nephrostomy or ureteral stent can be used to drain the affected upper urinary tract temporarily or permanently. Herein, we reported two cases of oncological patients affected by UAF and treated successfully by endovascular procedures. Furthermore, we performed a narrative review of the literature concerning UAF and its diagnostic and therapeutic management. Although our study did not allow us to state definitive conclusion about the diagnostic and therapeutic management of UAF due to small sample size, our findings support previous experiences in favour of the treatment of fistulas with an endovascular approach.

Pubovesical fistula (PVF) is a rare complication of radical treatments for prostate cancer (PCa), especially when a multimodal approach is performed. We present a case of PVF with extensive communication between the bladder and the pubic bones, and lymph node metastases of PCa treated by cystectomy and salvage lymphadenectomy. We describe a case of a 65-year old male patient who, after radical prostatectomy and adjuvant radiation therapy, suffered from suprapubic and perineal pain, ambulation difficulties and recurrent urinary tract infections. Cystoscopy, cystography and contrast-enhanced magnetic resonance imaging diagnosed a PVF. Choline positron emission tomography/computed tomography scan demonstrated PCa lymph node metastases. After the failure of conservative treatment, open radical cystectomy with ureterocutaneostomy diversion and salvage lymphadenectomy were performed with resolution of symptoms. At 3-month follow-up, the pelvic and perineal pain was completely regressed and 1-year later the patient was still asymptomatic. This clinical case shows efficacy and safety of combined salvage lymphadenectomy and cystectomy with urinary diversion for the treatment of late PCa node metastasis and PVF.

Introduction The Italian Radical Cystectomy Registry (Registro Italiano Cistectomie - RIC) aimed to analyse outcomes of a multicenter series of patients treated with radical cystectomy (RC) for bladder cancer. Material and methods An observational, prospective, multicenter, cohort study was performed to collect data from RC and urinary diversion via open (ORC), laparoscopic (LRC), or robotic-assisted (RARC) techniques performed in 28 Italian Urological Departments. The enrolment was planned from January 2017 to June 2020 (goal: 1000 patients), with a total of 1425 patients included. Chi-square and t-tests were used for categorical and continuous variables. All tests were 2-sided, with a significance level set at p <0.05. Results Overall median operative-time was longer in RARCs (390 minutes, IQR 335-465) than ORCs (250, 217-309) and LRCs (292, 228-350) (p <0.001). Lymph node dissection (LND) was performed more frequently in RARCs (97.1%) and LRCs (93.5%) than ORCs (85.6%) (p <0.001), with extended-LND performed 2-fold more frequently in RARCs (61.6%) (p <0.001). The neobladder rate was significantly higher (more than one-half) in RARCs. The median estimated blood loss (EBL) rate was lower in RARCs (250 ml, 165-400) than LRCs (330, 200-600) and ORCs (400, 250-600) (p <0.001), with intraoperative blood transfusion rates of 11.4%, 21.7% and 35.6%, respectively (p <0.001). The conversion to open rate was slightly higher in RARCs (6.8%) than LRCs (4.3%). Intraoperative complications occurred in 1.3% of cases without statistically significant differences among the approaches. Conclusions Data from the RIC confirmed the need to collect as much data as possible in a multicenter manner. RARCs proves to be feasible with perioperative complication rates that do not differ from the other approaches. [ABSTRACT FROM AUTHOR]

Introduction: Radical cystectomy with pelvic lymph node dissection is the gold standard treatment for non-metastatic muscle-invasive bladder cancer and high-risk non-muscle-invasive bladder cancer. For years, the traditional open surgery approach was the only viable option. The widespread of robotic surgery led to its employment also in radical cystectomy to reduce complication rates and improve functional outcomes. Regardless of the type of approach, radical cystectomy is a procedure with high morbidity and not negligible mortality. Data available in the literature show how the use of staplers can offer valid functional outcomes, with an acceptable rate of complications shortening the operative time. The aim of our study was to describe the perioperative outcomes and complications associated with robot-assisted radical cystectomy (RARC) with intracorporeal urinary diversion (ICUD) using a mechanical stapler., Material and Methods: From January 2015 to May 2021, we enrolled patients who underwent RARC with pelvic node dissection and stapled ICUD (ileal conduit or ileal Y-shaped neobladder according to the Perugia ileal neobladder) in our high-volume center. Demographic features, perioperative outcomes and early (≤30 days) and late (>90 days) post-operative complications according to the Clavien-Dindo classification, were recorded for each patient. We also analyzed the potential linear correlation between demographic, pre-operative as well as operative features and the risk of post-operative complications., Results: Overall, 112 patients who underwent RARC with ICUD were included with a minimum follow-up of 12 months. Intracorporeal Perugia ileal neobladder was performed in 74.1% of cases while ileal conduit was performed in 25.9%. The mean operative time, estimated intraoperative blood loss, and LOS were 289.1 ± 59.7 min, 390.6 ± 186.2 ml, and 17.5 ± 9.8 days, respectively. Early minor and major complications accounted for 26.7% and 10.8%, respectively. Overall late complications were 40.2%. The late most common complications were hydronephrosis (11.6%) and urinary tract infections (20.5%). Stone reservoir formation occurred in 2.7% of patients. Major complications occurred in 5.4%. In the sub-analysis, the mean operative time and the estimated blood loss improved significantly from the first 56 procedures to the last ones., Conclusion: RARC with ICUD performed by mechanical stapler is a safe and effective technique. Stapled Y-shaped neobladder did not increase the complication rate., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2023 Cochetti, Paladini, Del Zingaro, Ciarletti, Pastore, Massa, De Angelis and Mearini.)
