Percutaneous transrenal ureteroneocystostomy

Advanced cancer of the prostate causes mechanical obstruction of the ureteral orifice in 10% of patients. In our patient with advanced prostate carcinoma, after the usual method of placement of a ureteral stent had failed, antegrade percutaneous ureteroneocystostomy with placement of a double-J performed by means of the Lawson retrograde nephrostomy set. After removal of the stent 8 months later, the anastomosis functioned without a decrease in caliber until the patient died 2 years later. Our technique represents another new option for the treatment of such patients.
