Öğe Evaluation of conservative approach in the management of ureteroenteric strictures following radical cystectomy with Bricker ileal conduit: a single-center experience(TAYLOR & FRANCIS LTD, 2016) Baten, Evert; Akand, Murat; Floyd, Michael S., Jr.; Van Cleynenbreugel, Ben; Albersen, Maarten; Everaerts, Wouter; Van Poppel, HendrikObjective: The aim of this study was to evaluate the risk factors and treatment options for ureteroenteric strictures (UES) following radical cystectomy (RC) and ileal conduit (IC) formation, and specifically to comment on the conservative management of UES in asymptomatic patients. Materials and methods: The datasheets were reviewed of 304 consecutive patients who were treated with an RC and IC between January 2001 and May 2011 in a Belgian tertiary center and who followed a strict follow-up protocol. Long-term treatment outcomes were retrospectively analyzed. Results: Twenty-two patients (7.2%) were diagnosed with UES (affecting 27 ureters in total), when a new-onset hydroureteronephrosis or increase of the pre-existing hydroureteronephrosis was detected by ultrasound or computed tomography. A retrograde loopogram was then performed to confirm the UES. The mean follow-up time was 33 months. A decline in renal function, the presence of flank pain and urinary tract infections were indications for interventional treatment. Six patients underwent double-J stent placement, two patients received percutaneous nephrostomies as a definitive treatment and two patients underwent ureterointestinal reimplantation. Asymptomatic patients with a UES and a favorable renal function were conservatively managed. They remained asymptomatic during follow-up and required no active treatment. Conclusions: No clinical variable was independently associated with an increased risk of UES. These long-term data suggest that a selected patient population of asymptomatic patients with good renal function at the time of UES diagnosis can be safely managed conservatively.Öğe Impact of neoadjuvant chemotherapy on short-term complications and survival following radical cystectomy(SPRINGER, 2019) Milenkovic, Uros; Akand, Murat; Moris, Lisa; Demaegd, Liesbeth; Muilwijk, Tim; Bekhuis, Youri; Laenen, Annouschka; Cleynenbreugel, Ben Van; Everaerts, Wouter; Poppel, Hein Van; Dumez, Herlinde; Albersen, Maarten; Joniau, StevenObjectives To compare perioperative and short-term postoperative complication rates between patients receiving radical cystectomy (RC) after neoadjuvant chemotherapy (NAC) and patients undergoing RC alone. Secondary objectives were to compare overall survival (OS) and cancer-specific survival (CSS). Materials and methods Clinico-pathological data of all patients who received RC between 1996 and 2015 were retrospectively collected. Only patients with RC for muscle-invasive bladder cancer were included in the final analysis. Short-term (30-day) postoperative complications were assessed by registering the Clavien-Dindo classification (CDC) and dividing into sub-groups: low-grade (LGC) CDC 1-2 and high-grade (HGC) CDC 3-5. To compare populations with similar age, comorbidities and preoperative creatinine, we used a propensity score-adjusted statistical model. Pre- and perioperative predictors of short-term complications were identified using uni- and multivariable models. Survival was assessed using Kaplan-Meier analysis. Results A total of 491 patients undergoing RC were included, of whom 102 (20.8%) received NAC. After propensity score covariate adjustment, there was no significant difference in postoperative complications between patients undergoing NAC plus RC and RC alone with an overall complication rate of 69% and 66%, respectively. No significant differences in the 30-day HGC rates (11.76% and 11.83%, respectively) were observed. NAC plus RC patients had worse prognostic factors at baseline; nevertheless, after correction for group differences OS and CSS did not differ from RC only group (5-year OS 61.3% vs. 50.2%, and 5-year CSS 61.8% vs. 57.9% respectively, p > 0.05 for all). Conclusion In appropriately selected patients, exposure to NAC is not associated with increased short-term complications.Öğe The N-shaped orthotopic ileal neobladder: functional outcomes and complication rates in 119 patients(SPRINGER INTERNATIONAL PUBLISHING AG, 2016) De Sutter, Thomas; Akand, Murat; Albersen, Maarten; Everaerts, Wouter; Van Cleynenbreugel, Ben; De Ridder, Dirk; Goethuys, HansBackground: We report our long-term experience with 119 cases of N-shaped orthotopic ileal neobladder. Methods: Between March 1996 and July 2013, a total of 119 patients (102 men, 17 women) underwent cystectomy with creation of an N-shaped orthotopic ileal neobladder. The Clavien-Dindo classification score was used for grading early (<3 months postoperative), late, and pouch-related and non-pouch-related complications. Daytime and nighttime continence were evaluated for male and female patients separately, with patients subdivided in three groups: completely continent, use of <= 1 pad, and use of >1 pad. Results: Median follow-up was 75 months (range 3-204). Early complications (15 major, 54 minor) occurred in 39.5 % of 119 patients whereas 53.1 % presented with late complications (56 major, 39 minor; 111 patients evaluated). Urinary infection and outlet obstruction were both the most frequent early and late pouch-related complications; early non-pouch-related complications were mainly infectious and gastrointestinal, and the most common late non-pouch-related problem was wound herniation. At 12 months, 96 and 60 % of the men and 84.6 and 66.7 % of the women respectively achieved daytime and nighttime continence. Conclusion: Complication rates of the N-shaped orthotopic ileal neobladder were relatively high, probably because of meticulous recording and follow-up. Daytime continence rates were better than nighttime rates. N-shaped orthotopic ileal neobladder can be a good option for urinary diversion in selected patients who undergo radical cystectomy.Öğe Prognostic score predicts overall survival following complete urinary tract extirpation(TAYLOR & FRANCIS LTD, 2020) Akand, Murat; Muilwijk, Tim; Van Der Aa, Frank; Gevaert, Thomas; Milenkovic, Uros; Moris, Lisa; Blyweert, Wim; Poppel, Hendrik Van; Albersen, Maarten; Joniau, StevenPurpose: To evaluate the oncological outcome and complications of patients treated with complete urinary tract extirpation (CUTE) in our department, and to identify prognostic factors for survival. Methods: Clinico-pathological data of patients treated with one-step or stepwise CUTE between 1999 and 2017 were collected retrospectively. Complications were classified according to the modified Clavien-Dindo classification (CDC) in the early (<= 30 days) and late (>30 days) follow-up. Log-rank test was used to assess independent predictors of overall survival (OS), cancer-specific survival (CSS) and recurrence-free survival (RFS). Results: Twenty-five patients (20 male) underwent CUTE (16 one-step) for BC + unilateral/bilateral UTUC. Minor (CDC 1-2) and major (CDC3-5) complications were observed in 72% and 40% of patients, respectively, in the early postoperative period (<= 30 days). Five (20%) patients died in the perioperative period (CDC 5) with a median OS of 52 days (range: 25-77). Median time to last follow-up or death was 30 months (range: 0-161). Median OS was 50 months (95% Confidence Interval [CI]: 22-118 months), while median CCS and RFS were not reached. The 5-year OS, CSS and RFS were 42.7%, 69.6% and 66.7%, respectively. A score for determining which patients would benefit from CUTE was arbitrarily developed, and showed that the patients with a score of 0-2 points (good prognosis) had a better OS than the patients with a poor prognosis (3-4 points) in the log-rank test. Conclusions: Because of lower OS rates, patients with ESRD or with a CUTE score of 3-4 points are probably not ideal candidates for CUTE.
