Long-term complications of conduit urinary diversion.
ABSTRACT We evaluated long-term surgical complications and clinical outcomes in a large group of patients treated with conduit urinary diversion.
We identified 1,057 patients who underwent radical cystectomy with conduit urinary diversion using ileum or colon at our institution from 1980 to 1998 with complete followup information. Patients were followed for long-term clinical outcomes and analyzed for the incidence of diversion specific complications.
A total of 844 patients died at a median of 4.1 years (range 0.1 to 28.1) following cystectomy. Median followup of the surviving 213 patients was 15.5 years (range 0.3 to 29.1). There were 643 (60.8%) patients with 1,453 complications directly attributable to the urinary diversion performed with a mean of 2.3 complications per patient. Bowel complications were the most common, occurring in 215 patients (20.3%), followed by renal complications in 213 (20.2%), infectious complications in 174 (16.5%), stomal complications in 163 (15.4%) and urolithiasis in 162 (15.3%). The least common were metabolic abnormalities, which occurred in 135 patients (12.8%), and structural complications, which occurred in 122 (11.5%). Increasing age at cystectomy (HR 1.21, p <0.001), increasing Eastern Cooperative Oncology Group performance status (HR 1.23, p = 0.02) and recent era of surgery (HR 1.68, p <0.001) were significantly associated with a higher incidence of complications.
Conduit urinary diversion is associated with a high overall complication rate but a low reoperation rate. Long-term followup of these patients is necessary to closely monitor for potential complications from the urinary diversion that can occur decades later.

ABSTRACT: Calculus formation in an ileal conduit following cystectomy is a known complication. Encrustation and formation of calculus may also occur over a DJ stent retained for a long period; but this is never reported in patients with conduit diversion because of close surveillance of these patients. Here we report first case of a large calculus encrusted over a forgotten DJ stent within an ileal conduit in a man who had undergone urinary diversion following radical cystectomy for carcinoma urinary bladder 8 years earlier08/2014; 2014.

ABSTRACT: We report on the short and late morbidity and mortality of ileal conduit and neobladder after radical cystectomy with their associated risk factors. We retrospectively collected data on 308 non-metastatic bladder cancer patients who underwent radical cystectomy with either ileal conduit or neobladder for a curative intent from January 1999 to December 2011. Post-operative morbidity and mortality of 30-day (early) and 90-day (late) complication with their risk factors were examined in association with different types of urinary diversion. A comparative analysis using propensity-score matching was performed with matching variables of age, sex, number of underlying diseases and pathologic T and N stages, lymph node dissection, operative time and time of surgical year for comparison of the early and late morbidities between ileal conduit and neobladder. During the median follow-up of 46.6 months, early and late morbidities were 29.5% (n = 91) and 19.8% (n = 61), and complication-related mortalities were 2.2 and 6.6%, respectively. The type of urinary diversion significantly affected only the late complications (early: neobladder 57 vs. ileal conduit 47, P = 0.096; late: neobladder 67 vs. ileal conduit 37, P < 0.001). However, after propensity-score matching, no significant differences in early and late morbidities were observed between neobladder and ileal conduit. For risk factors of morbidity, number of removed lymph node states and hypertension were independently significant for both early and late complications (P < 0.05). The type of urinary diversion affected only late complication, however, results of the matching analysis showed no significant differences in early and late morbidities between neobladder and ileal conduit .Japanese Journal of Clinical Oncology 05/2014; 44(7).

ABSTRACT: Purpose We evaluated the outcome in patients with late recurrence of urothelial carcinoma after radical cystectomy. Materials and Methods We identified 2,091 patients who underwent radical cystectomy at our institution between 1980 and 2006. Survival was estimated using the Kaplan-Meier method and compared based on recurrence timing (less than 5 years vs 5 or greater) and location (urothelial vs nonurothelial) using the log rank test. Cox proportional hazard regression models were used to evaluate variables associated with late recurrence and death from bladder cancer. Results Median postoperative followup was 16.6 years. Late recurrence was identified in 82 patients (3.9%). On multivariate analysis younger age (p = 0.0008), nonmuscle invasive disease (p = 0.01) and prostatic urethral involvement (p <0.0001) were significantly associated with an increased risk of late recurrence. Five-year post-recurrence cancer specific survival was significantly worse after recurrence within 5 years from radical cystectomy vs after late recurrence (17% vs 37%, p = 0.001). Patients with nonurothelial late recurrence had adverse 5-year cancer specific survival compared to those with urothelial late recurrence (19% vs 67%, p <0.0001). On multivariate analysis younger patient age (HR 1.01, p = 0.003), muscle invasive disease (HR 1.31, p <0.0001) and nonurothelial recurrence site (HR 2.76, p <0.0001) but not time to recurrence (p = 0.38) were associated with a significantly increased risk of death from bladder cancer following recurrence after radical cystectomy. Conclusions Late recurrence is uncommon after radical cystectomy. Younger patient age, nonmuscle invasive disease and prostatic urethral involvement were associated with a significantly increased risk of late recurrence. Interestingly, time to recurrence was not associated with a subsequent risk of patient death.The Journal of Urology 05/2014; 191(5):1256–1261. DOI:10.1016/j.juro.2013.11.103 · 3.75 Impact Factor
