Summary
The purpose of this study is to evaluate the safety and efficacy of the Memokath 051 ureteral stent as a long-term temporary and minimally invasive means of providing ureteral drainage in the setting of malignant extrinsic ureteral obstruction secondary to inoperable abdominal or pelvic malignancies. Up to 15 adults who have extrinsic ureteral obstruction secondary to an inoperable abdominal or pelvic malignancy and need ureteral stent drainage will undergo outpatient placement of the ureteral stent. Ongoing monitoring will continue for as long as the stent is in place.
