Abstract

INTRODUCTION:

Upper urinary tract occlusion is well recognized in patients with chronic ketamine abuse. The mechanism is generally unknown, but the ulcerative cystitis contracture may be responsible for obstruction. We present the first reported use of the Resonance metallic ureteric stent in the management ureteric obstruction caused by ketamine-induced uropathy.

PRESENTATION OF CASE:

A 31-year-old lady with one-year history of recreational ketamine abuse presented with symptoms related to drug-induced ulcerative cystitis over twelve-months. She presented with acute renal failure with bilateral pyonephrosis and sepsis, and was initially treated with bilateral nephrostomy insertions and antegrade stenting. The J stents recovered the renal function, but the patient suffered from recurrent urinary tract infections (UTI's) with the prosthesis in-situ. The patient successfully underwent bilateral insertion of 12cm 6.0 French Cook Resonance metallic ureteric stents. One year following the placement of the metallic stents, the patient maintained optimal renal function with no episode of UTI.

DISCUSSION:

Ketamine induced uropathy is a well documented complication of chronic drug-induced ulcerative cystitis. The mechanical strength and inert property of metallic ureteric stents make it an ideal device to manage this problematic benign cause of ureteric obstruction.

CONCLUSION:

This is the first reported case of therapeutic bilateral metallic ureteric stents in the management of patients with ketamine induced uropathy with one year follow up.
