Popis: Background Little has been reported on urological complications of total pelvic exenteration (TPE) for locally advanced or recurrent rectal cancer. Objective To assess urological reconstructive outcomes and adverse events in this setting. Design, setting, and participants A total of 104 patients underwent TPE from 2004 to 2016 in this single-centre, retrospective study. Electronic and paper records were evaluated for data extraction. Mean follow-up was 36.5 mo. Intervention TPE. Outcome measurements and statistical analysis Urological complications were analysed using two-tailed t and chi-square tests, binary logistic regression analysis. Results and limitations Sixty-three (61%) patients received radiotherapy prior to TPE. Incontinent diversions included ileal conduit (n = 95), colonic conduits (n = 4), wet colostomy (n = 1), and cutaneous ureterostomy (n = 1). Three patients had a continent diversion. The overall urological complication rate was 54%. According to Clavien-Dindo classification, 30 patients, five patients, and one patient had grade III, IV, and V complications, respectively. The commonest complication was urinary tract infection (in 32 [31%] patients). Anastomotic leaks were seen in 14 (13%) cases, of which eight (8%) were urinary leaks. Fistulas were seen in three (3%) patients, involving the urinary system. A return to theatre was required in 12 (12%) patients. Ureteroenteric strictures were seen in seven (7%). No differences were seen in urological outcomes in patients with primary or recurrent rectal cancer (p = 0.69), or by radiation status (p = 0.24). The main limitation is the retrospective nature of the study. Conclusions TPE is complex with recognised high risk of morbidity. In this cohort, there was no significant difference in outcomes between primary and recurrent disease, and surgery after radiation. Patient summary In this study, we assessed urological complications following total pelvic exenteration. Urinary complications affected more than half of patients. Urinary tract infection is the commonest risk. Approximately one-third of patients required surgical, radiological, or endoscopic intervention ± intensive care admission. Radiation prior to the operation did not affect urinary complications.
