ObjectivesTo determine the incidence, risk factors and causes of hospital readmission in a large series of patients who underwent radical cystectomy (RC) and urinary diversion. Patients and MethodsWe retrospectively analysed the data of 1000 patients who underwent RC and urinary diversion between January 2004 and September 2009 in our tertiary referral centre. Patients stayed in hospital for 21 and 11 days for orthotopic and ileal conduit diversions, respectively. The primary outcome was the development of a complication requiring hospital readmission at ≤3 months (early) and >3 months (late). Causes of hospital readmissions were categorised according to frequency of readmissions. Predictors were determined using univariate and multivariate logistic regression models. ResultsIn all, 895 patients were analysed excluding 105 patients because of perioperative mortality and loss to follow-up. Early and late readmissions occurred in 8.6% and 11% patients, respectively. The commonest causes of first readmission were upper urinary tract obstruction (UUO, 13%) and pyelonephritis (12.4%) followed by intestinal obstruction (11.9%) and metabolic acidosis (11.3%). The development of postoperative high-grade complications (odds ratio [OR] 1.955; 95% confidence interval [CI] 1.254-3.046; P = 0.003) and orthotopic bladder substitution (OR 1.585; 95% CI 1.095-2.295; P = 0.015) were independent predictors for overall hospital readmission after RC. Postoperative high-grade complications (OR 2.488; 95% CI 1.391-4.450; P = 0.002), orthotopic bladder substitution (OR 2.492; 95% CI 1.423-4.364; P = 0.001) and prolonged hospital stay (OR 1.964; 95% CI:1.166-3.308; P = 0.011) were independent predictors for early readmission while hypertension (OR 1.670; 95% CI 1.007-2.769; P = 0.047) was an independent predictor for late readmission. ConclusionHospital readmissions are a significant problem after RC. In the present study, UUO, pyelonephritis, metabolic acidosis and intestinal obstruction were the main causes of readmission. Orthotopic bladder substitution and development of postoperative high-grade complications were significant predictors for overall readmission.

ObjectiveTo review the incidence, predictors and prognosis of bladder cancer recurrence after management of upper tract urothelial carcinoma (UTUC).Patients and methodsWe retrospectively reviewed patients who were surgically treated for UTUC from 1983 to 2013. The tumours were categorised according to the 1997 Tumour-Node-Metastasis (TNM) staging and the three-tiered World Health Organization grading systems. The primary endpoint was the occurrence of any intravesical recurrence after treatment. We studied the possible risk factors that may contribute to development of intravesical recurrence, as well as the prognosis of the patients who had recurrence.ResultsIn all, 297 patients were eligible for analysis. Recurrent bladder tumours occurred in 139 patients (46.8%). The mean (range) time to recurrence after surgery was 33 (6–300) months. Neither sex, past history of bladder tumours, concomitant bladder tumour, the side of the tumour, UTUC stage, grade, presence of carcinoma in situ or multicentricity at the time of diagnosis of UTUC, were significant predictors of intravesical tumour recurrence. Ureteric tumour was the only identified risk factor (P = 0.02). Post-treatment bladder recurrence was a significant predictor of later urethral recurrence (P = 0.002).ConclusionsIn our present series, bladder cancer recurrence of urothelial malignancy occurred in nearly half of the patients after surgical management of UTUC. Ureteric tumour was the only identifiable risk factor, thus patients with ureteric tumours may benefit from prophylactic intravesical chemoimmunotherapy. Bladder recurrence does not appear to affect the cancer-specific survival after surgical management of UTUC.
