[Palliative diversion using an autostatic ureteral stent after endoscopic resection of the ureteral meatus in T4 pelvic tumors].

Seven patients with renal failure secondary to bilateral ureteric obstruction by pelvic carcinoma underwent palliative urinary diversion. In 3 cases, an autostatic ureteric stent was inserted after endoscopic resection of the trigone invaded by the tumour in the presumed zone of the ureteric meatus, and retrograde catheterisation of the ureter. This method has very limited indications, but may improve the comfort of survival of certain patients.
