Case Discussion: Kidney stone in a patient with an ileal conduit

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.Supplementary video abstracthttp://links.lww.com/COU/A32.

Case report: Treatment of urinary calculi using percutaneous nephrolithotomy in patient with ileal conduit and history of bladder transitional cell carcinoma

Urinary calculi are a frequent complication of urinary diversion following radical cystectomy, including in ileal conduit systems. We report the case of a 38-year-old man with ileal conduit urinary diversion, following radical cystectomy for transitional cell cancer, who presented with symptomatic bilateral kidney stones. By reporting the medical record and management procedure for this patient, we aim to demonstrate the successful management of kidney stones via supine percutaneous nephrolithotomy, using an Alken telescopic metal dilator, under spinal anesthesia. Consistent with most literature, percutaneous nephrolithotomy was the best management procedure in this case.
