Summary
Brief summary (as posted)
Malignant ureteral obstruction (MUO) is an extrinsic ureteral obstruction caused by malignant diseases. This study aim to compare tandem 6 Fr Percuflex™ stents and single large-caliber 8Fr silicone stent in patients with MUO. The primary endpoint is stent failure rate. The secondary endpoints are patient comfort, quality of life and overall survival.
