Predicting Factors for Stent Failure-Free Survival in Patients With a Malignant Ureteral Obstruction Managed With Ureteral Stents

Abstract

A mid or lower ureteral obstruction, GPS ≥1, and serum creatinine before ureteral stent insertion >1.2 mg/dL were unfavorable predictors of stent failure-free survival. These factors may help urologists predict survival time.
