Percutaneous Nephrostomy in Patients with Ureteral Obstruction Secondary to Pelvic Tumor / 대한비뇨기과학회지

ABSTRACT

Percutaneous nephrostomy was done in 18 cases for ureteral obstruction secondary to advanced pelvic malignancy from Jan.1990 to Apr.1993. The most common site of the primary malignancy was cervix ( 77% ). The mean survival time after diversion was 4.2 months ; 22.2% (4/18) of the patients lived more than 6 months, and 1 patient is alive at 4 months. In 4 patients the renal function was not improved, whose mean survival time was 1.4 months. We consider that close. periodic follow-up is mandatory to detect the ureteral obstruction in patients With malignant pelvic tumor and early management may improve the survival time. The patients who had previously urinary diversion for unilateral ureteral obstruction should be evaluated periodically for contralateral renal function. However, the exact criteria for the selection of patients for urinary diversion is, not obvious.
