Complications After Ileal Urinary Derivations

Introduction: The aim of the study was to determine the most frequent early and late complications in different types of ileal urinary diversions. Patients and methods: The study was conducted in a five-year period, on 106 patients who were diagnosed with invasive urinary bladder cancer and who had indication for radical cystectomy with one of the investigated types of urine derivation. They were divided into 2 groups, based on the type of ileal urinary diversions. Results: The colonization of bacteria was more prominently present in the ileal conduit urinary diversion group (97%) compared to Ghoneim (25%) and Hautmann (10%) group, Ureteral stenosis was slightly less represented in the conduit group (9.1%). Wound infections were significantly more represented in the conduit (21.2%) than in the Ghoneim group (5%) Nighttime incontinence was present in 20% of patients in both groups or 4 patients in each group. Daytime incontinence in the Ghoneim group was present in 3 patients (15%) and in the Hautmann group 2 patients (10%). Late complications correlate significantly negative with the type of surgery and slightly negative with the grade, and significantly positively with the examined group and T stage, and slightly correlate positively to the N and R stages. Early complications correlate slightly negative with the type of surgery, slightly negative with the grade, and significantly positively with T stage, and slightly positively correlates with the N and R stage. Conclusion: The most commonly reported complications in ileal conduit are: prolonged ileus, stoma infection, wound dehiscence and bacterial colonization, followed by peristomal skin complications and complications related only to the stoma, such as stenosis and stoma retraction, and prolaps of ileostoma and ileointestinal stenosis. The ileus rate in orthotopic derivation was significantly lower than that of the ileal conduit group, which led to the conclusion that the neomybladder position does not disturb the anatomic abdominal structure.
