A Customized Reinforced 8-French Ureteral Stent with End-Piece to Decrease Ureteral Obstruction and Alleviate Stent-Related Symptoms: Evaluation of 92 Patients with 319 Ureteral Stent Procedures

The absence of repeated obstructions appears to improve the survival of patients with malignant disease, but this finding requires validation in a prospective randomized controlled trial. Future stents should integrate these important stent characteristics.
