Background and Purpose: Extrinsic ureteral obstruction caused by various malignancies often necessitates urinary diversion. The use of single ureteral stents as a form of urinary diversion results in a high failure rate, while the use of two ipsilateral stents has shown promising results. We report our experience using the latter technique. Patients and Methods: Between 1996 and 2001, four male and three female patients with a mean age of 65 years (range 37-95 years) who had extrinsic compression of the ureters underwent single stent management to relieve obstruction. Ureteral obstruction was secondary to prostate cancer (N = 3), cervical cancer (2), nonHodgkin’s lymphoma (1), and transitional-cell cancer of the bladder and ureter (1). After failure of such management, two 7F stents or a combination of 8F/6F double-J ureteral stents were placed. The stents were changed every 4 to 6 months. Follow-up included serial renal ultrasound scans and serum creatinine measurements. Results: Ureteral stricture length ranged from 2 to 4 cm. Insertion of two double-J ureteral stents in a single ureter was successful in all cases. During the mean follow-up of 16 months (range 1-38 months), the ureteral stents were tolerated by all patients, without significant discomfort. Marked improvement of hydronephrosis and alleviation of flank pain was noted in all patients. Three patients have died at 1 to 3 months. Renal function improved, with a mean decline in the serum creatinine concentration from 3.2 mg/dL to 1.48 mg/dL in the five patients tested. Conclusion: Simultaneous placement of two double-J ureteral stents for the management of ureteral obstruction secondary to a malignancy is a safe and effective technique.
