The functioning and the complication rate of extreme long existing urinary diversions.

PURPOSE OF REVIEW This review is timely and relevant because many patients live many years with urinary diversions. Knowledge about the long term outcome with respect to function and complications are important for patient counseling and for the manner to follow-up patients. This study was performed to investigate the functioning of urinary diversions constructed > 25 years earlier. RECENT FINDINGS Most studies have a relatively shorter follow-up, mainly focussing on short term postoperative complications. Focussing on the long term, urinary tract infections (UTI) including pyelonephritis are common. Mild kidney function deterioration is described. SUMMARY Retrospective study (2018-2019); 43 patients with regular follow-up at the Radboud University Medical Centre Nijmegen the Netherlands. Ileal conduit (n = 19) and ureterosigmoidostomy (n = 11) are the most common diversion types for reasons such as: bladder exstrophy (n = 15), urinary incontinence (n = 9) and malignancy (n = 8). This series with a median follow-up of 40 years, shows it is possible to live and cope with a urinary diversion for a very long time. Ureterosigmoidostomies give relatively good results. Ileal conduits are functioning properly with acceptable complication rates. 95% suffers from chronic UTI's. Kidney function deterioration was mild. Diversions for benign reasons have more complex complications compared to diversion constructed for malignant reasons. VIDEO ABSTRACT http://links.lww.com/COU/A32.
