Percutaneous Nephrostomy versus Indwelling Ureteral Stents in Patients with Bilateral Nongenitourinary Malignant Extrinsic Obstruction

We present five cases of bilateral extrinsic ureteral obstruction in advanced nongenitourinary abdominal malignancy. They show the superiority of percutaneous nephrostomy to indwelling ureteral stents in providing diversion. We suggest that percutaneous nephrostomy drainage should be the management of choice in extrinsic obstruction by advanced abdominal malignancies.
