Abstract
PURPOSE To identify preoperative predictors of endo-urological treatment (EUT) failure while promoting a new diagnostic and therapeutic pathway for benign uretero-enteric anastomosis stricture (UES) management after radical cystectomy (RC). MATERIALS AND METHODS We relied on a prospectively maintained database including 96 individuals (122 renal units) who developed a benign UES at our institution between 1990 and 2018. UES was classified into two different types according to morphology: FP1 (i.e., sharp or duckbill) and FP2 (i.e., flat or concave). EUT feasibility, success rate, as well as intra and postoperative complications were recorded. Uni- and multivariable logistic regression analysis (MVA) assessed for predictors of EUT failure. RESULTS Overall, 78 (63.9%) and 32 (26.3%) cases were defined as FP1 and FP2, respectively. EUT was not feasible in 33 (27.1%) cases. After a median follow-up of 50 (IQR 5-240) months, successful treatment was reached only in 15/122 (12.3%) cases. EUT success rates raised when considering short (< 1 cm) (16.8%), FP1 morphology (16.7%) strictures, or the combination of these characteristics (22.4%). Overall, 5 (5.2%) cases had CD ≥ III complications. FP2 (OR: 1.91, 95%CI 1.21-5.31, p = 0.03) and stricture length ≥ 1 cm (OR: 9.08, 95%CI 2.09-65.71, p = 0.009) were associated with treatment failure at MVA. CONCLUSIONS Endoscopic treatment for benign UES after RC is feasible but harbors a low success rate. Stricture length and radiological morphology of the stricture are related to endoscopic treatment failure. Surgeons should be aware of the stricture features during the preoperative decision-making process to choose the optimal candidate for endoscopic treatment.

An experimental study of magnetic compression technique for ureterovesical anastomosis in rabbits. Sci Rep 2023; 13:1708. [PMID: 36720998 PMCID: PMC9889304 DOI: 10.1038/s41598-023-27715-z] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/13/2022] [Accepted: 01/06/2023] [Indexed: 02/01/2023] Open
Abstract
This study aimed to explore the feasibility of the magnetic compression technique (MCT) for ureterovesical anastomosis in a rabbit model with ureteral obstruction. The distal ureteral obstruction model using female New Zealand rabbits was induced by ligating the distal end of the right ureter with silk thread for four weeks. A pair of cylindrical NdFeB magnets (daughter magnet and parent magnet) with a hole in the center was used for the ureterovesical anastomosis. The daughter magnet and the parent magnet were respectively placed close to the obstruction site through the dilated proximal ureter and urethra, and then the daughter-parent magnets pair was attracted together automatically. Postoperative X-rays were taken to confirm the position of the magnets. The anastomotic stoma specimens were obtained two weeks postoperatively, and the anastomotic stoma formation was observed by the naked eye and histological staining. The operation time and the anastomotic burst pressure were measured. The ureter was significantly dilated in the fourth week after ligation, which satisfied the placement of the daughter magnet. The ureterovesical magnet placements were successfully performed in ten experimental rabbits, with an operation time of 36.5 ± 6.09 min. The parent and daughter magnets attracted each other well and were subsequently removed through the urethra two weeks postoperatively, resulting in the establishment of ureterovesical anastomosis. The anastomotic burst pressure was 147.5 ± 14.59 mmHg. Gross specimens and histological examination of the anastomotic stoma showed that the anastomotic stoma healed well. MCT is feasible and simple for ureterovesical anastomosis.

Comparative Analysis of Elderly Patients Undergoing Radical Cystectomy With Ureterocutaneostomy or Ileal Conduit With a Special Focus on Bowl Complications Requiring Surgical Revision. Front Surg 2022; 9:803926. [PMID: 35756464 PMCID: PMC9226401 DOI: 10.3389/fsurg.2022.803926] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/28/2021] [Accepted: 03/29/2022] [Indexed: 11/13/2022] Open
Abstract
ObjectivesIleal conduits (ICs) carry an additional perioperative complication risk due to the bowel procedure. This analysis compares surgical outcomes in patients ≥75 years of age with ureterocutaneostomy (UCN) and IC after cystectomy (Cx).MethodsData of 527 patients included in a retrospective cystectomy database of two high volume centers (2008–2020) were queried to identify elderly patients (≥75 years) who underwent Cx either with IC or UCN. Patient characteristics of all patients [age, BMI, Charlson Comorbidity Index (CCI)], perioperative parameters (operation time, blood loss, transfusions, tumor stage), and postoperative complications (clavien >IIIA, intensive care unit (ICU) stay) were compared. As special focus, bowel complications requiring surgical revision (rBCs) were analyzed. In patients with IC, the rate of ureteral implantation stenosis (USt) was recorded. As a population of special interest, patients ≥80 years of age were analyzed separately. Categorical data were compared using Fisher exact test, and continuous data were compared using Mann–Whitney U test.ResultsA total of 163 patients ≥75 years of age (125 IC, 38 UCN) were identified. Patients with UCN were older and presented with a higher CCI, though differences were not statistically different. Surgery with palliative intent was more frequent in patients with UCN (37 vs. 10%). Operation time in UCN was significantly shorter (233 vs. 305 min, p = 0.02), while blood loss and transfusion rate were comparable. Overall complication rate (Clavien-Dindo grade IIIA–IVB) was comparable (UCN 34% vs. IC 37%). However, rBC was a rare complication in UCN (3/38) as compared to patients with IC (15/125). Frequency of postoperative ICU stay (UCN 16% vs. IC 16%) and 90-day mortality did not differ (UCN 3/38 patients, IC 5/125 patients). Regarding long-term follow-up, USt requiring revision or permanent stenting was seen in 18/125 (14%) patients with IC. In patients >80 years of age, results were comparable to the main cohort. Low event rate regarding complications and bias inherent of a retrospective analysis (selection bias, unequal distribution in case numbers) precludes detection of statistical differences regarding patients' characteristics and overall complication rate.ConclusionUCN is an alternative to IC in elderly and/or frail patients. Severe bowel complications are numerically less frequent and operation time is minimized.

Abstract
Background Orthotopic neobladder reconstruction has become the preferred method of urinary diversion after radical cystectomy in major medical centers. We performed modified Y-shaped ileal orthotopic neobladder reconstruction and presented the functional results and postoperative complications of the modified surgery. Methods We included 21 patients with bladder cancer who underwent radical cystectomy at our center between February 2019 and December 2019. All patients underwent robotic-assisted laparoscopic radical cystectomy and lymph node dissection plus modified Y-shaped ileal orthotopic neobladder reconstruction. We collected the demographic and pathological history of the patients, and perioperative and postoperative functional outcomes and postoperative complications were recorded. Results All surgeries were successful and no serious postoperative complications occurred. The mean operative time was 321.43 ± 54.75 min, including 101.67 ± 10.88 min required for neobladder reconstruction. Liquid intake was encouraged about 5 days after surgery, stent and catheter were removed after 13.52 ± 3.28 days, and the patients were discharged 1–2 days after removing the catheter. No ureteral anastomotic and neobladder urethral anastomotic strictures occurred. The volume of the neobladder at 1-year post-surgery was 195.24 ± 16.07 mL and the maximum urinary flow rate was 20.64 ± 2.22 mL/s. Conclusion We describe the robotic-assisted modified Y-shaped ileal orthotopic neobladder reconstruction performed at our center, which requires a simple suture and short neobladder construction time, minimizes the occurrence of anastomotic stenosis, facilitates smooth patient emptying, and is clinically scalable and applicable.

Abstract
PURPOSE To evaluate the clinical efficacy and safety of drug-coated balloon (DCB) ureteroplasty for the management of non-malignant ureteral strictures. MATERIAL AND METHODS A prospective "off-label" monocentric single-arm pilot study investigating the safety and efficacy of drug-coated balloon (DCB) (Lutonix®; BD, USA) was performed. Twenty-five patients with benign ureteral strictures related to uretero-enteric anastomosis (n = 13); lithiasis (n = 5), post-surgical complications (iatrogenic n = 5), transplanted kidney (n = 1) and post-radiotherapy (n = 1) were included. Following lesion crossing, predilatation was performed using 4-7 mm high-pressure balloon catheter (5-6Fr) with a balloon pressure of 6-7 atm based on the manufacturer's recommendation. In the absence of rupture of the ureteral wall, the DCB was dilated for 4 min. across the lesion. The process was repeated if deemed necessary to a maximum of three stricture dilatations. We analysed both clinical and radiological primary patency (no signs of ipsilateral hydronephrosis or improvement of the existing residual dilatation at the follow-up examinations) and secondarily safety endpoints. RESULTS Mean lesion length was 40 ± 28.5 mm. Mean time follow up was 36 months ± 10.46 months. Strictures were located at upper ureteric (12%), lower ureteric (32%), ureterovesical anastomosis (4%) and uretero-enteric anastomosis (52%) levels. The overall radiological success at 1-year follow-up was 88% (22/25 patients). In 56% patients (14/25 patients with primary patency) the nephrostomy catheter was removed 21 days following a single DCB procedure. In 32% (8/25 patients) an additional dilatation sessions were required for maintaining the ureteral patency. The overall failure rate at 1-year follow-up was 12% (3/25 patients). Only one case of febrile urinary tract infection in a female patient (acute pyelonephritis) was encountered after the first dilatation. CONCLUSIONS Paclitaxel-coated balloon ureteroplasty proved to be safe and effective for the treatment of non-malignant ureteral strictures. Larger studies are warranted to validate these promising initial results.

Abstract
Background Balloon dilation is a commonly used minimally invasive endourological treatment of ureteral stricture, but the postoperative recurrence rate is relatively high. And factors contributing to recurrence after treatment are poorly understood. Herein, we sought to develop a novel clinical nomogram to predict ureteral stricture-free survival in patients suffering from ureter stricture and performed balloon dilation. Methods The nomogram was established based on a retrospective analysis of 321 patients who received endoscopic balloon dilation alone for ureter strictures from January 2016 to January 2020 in Sun Yat-sen Memorial Hospital using the Cox regression model. Perioperative clinical data and disease outcomes were analyzed. The primary endpoint was the onset of ureteral re-stricture after ureter balloon dilation. Discrimination of the nomogram was assessed by the concordance index (C-index) and the calibration curve. The results were internally validated using bootstrap resampling. Results Overall, 321 patients with a median follow-up of 590 days were enrolled in the study, among which 97 patients (30.2%) developed recurrence of ureteral stricture during follow-up. Five variables remained significant predictors of ureteral re-stricture after multivariable analyses: stricture nature (P < 0.001), urinary nitrite (P = 0.041), CKD (P = 0.005), stent retention time (P < 0.001), and balloon size (P = 0.029). The calibration craves for the probability of 1-, 3-, and 5-years stricture-free survival (SFS) presented satisfied with the consistency of nomogram prediction and actual observation. The C-index of the model was 0.74 (95% CI 0.70–0.79). Conclusions Our study developed the first nomogram to effectively predict stricture-free survival in patients suffering from ureter stricture after balloon dilation. It is helpful to identify the optimal patients with ureter stricture for balloon dilation and improve treatment outcomes. However, further external validation of the nomogram is warranted.

Abstract
INTRODUCTION Uretero-enteric stricture (UES) is a common post-operative complication after radical cystectomy with urinary diversion. The aim of this systematic review is to discuss the contemporary management of benign UES after cystectomy and to compare the different surgical approaches. EVIDENCE ACQUISITION A systematic review was performed from January 2000 through January 2021. Search engines used included PubMed, Embase and Medline databases. Search query was: ((ureteroileal OR uretero-ileal OR ureteroenteric OR ureteroenteric) AND (stricture OR stenosis)) AND (management OR treatment). Study selection followed the PRISMA statement. Studies tackling management of UES, either through open, endoscopic, laparoscopic or robot-assisted approaches, were included in our systematic review. EVIDENCE SYNTHESIS Forty-one studies were finally included in this systematic review. No prospective studies were found; all included studies were retrospective. Open surgical repair had a 78-100% success rate, a significant rate of complications, and a low recurrence rate (6-8%). Endourological management decreased complication rate, length-of-stay, and blood loss, with however lower success (15-50%) and higher recurrence rates (62%-91%) compared to open surgery. Robotic assisted surgery showed comparable success rates to open surgery (80-100%), while limiting the number of major complications and hospital length-of-stay. CONCLUSIONS Surgical management of UES remains challenging. Open surgery maintains a role given its high success rate, at the cost however of a significant morbidity. On the other hand, endourological procedures offer a favorable and low complication risk, but a low long-term success rate. Robotic-assisted surgery is emerging with a valid resolution of UES as it offers comparable success rates to an open approach, while reducing surgical morbidity. Head-to-head comparisons are awaited to confirm these findings.

Abstract
Objective: To evaluate the safety and efficacy of endoscopic procedures for ureteroenteric anastomotic strictures (UESs) after radical cystectomy and urinary diversion. Methods: We performed a meta-analysis of relevant articles through March 2020 using PubMed, Embase, and Cochrane Central Register to assess the efficacy of endoscopic procedures in UES according to the PRISMA and PICOS criteria. The main endpoints were success rate and complications, and we also compared the efficacy of different methods and stricture length and side in UES. Cochrane Collaboration's Revman version 5.3 and Stata version 15.1 software were used for statistical analysis. Results: A total of 18 retrospective studies with 697 patients were included. The median follow-up ranges from 12 to 62.5 months. Patients treated with endoscopic procedures had an overall success rate of 46%. The pooled rate of Clavien-Dindo ≥ 3 complications was 3.8% among included studies. Laser vaporization and stent insertion (48 and 47%) had a relatively high success rate than balloon dilatation (35%). In subgroup analysis, the success rate of endoscopic procedures for ≤ 1-cm strictures was significantly higher than that for >1-cm ones [odds ratio (OR), 8.65; 95% confidence interval (CI), 3.53-21.21; P < 0.00001]. In addition, the success rate in cases with strictures of the right side was relatively higher than that in cases with strictures of the left side (OR, 1.72; 95% CI, 1.05-2.81; P = 0.03). Conclusion: Our pooled studies showed that endoscopic operation is feasible and associated with a moderate success rate along with a relatively low incidence of perioperative complications in the treatment of UES, especially with length ≤ 1 cm and right side. Although there is still no consensus on endoscopic technique for UES regarding balloon dilatation, stent insertion, and laser vaporization, we believe that endoscopic management is a safety and available approach for UES with close follow-up.
