OBJECTIVE: To evaluate the endourological technique in the treatment of bilateral malignant ureteric obstruction.
METHODS: The data of 43 patients (totally, 70 cases) with bilateral malignant ureteric obstruction treated with endoluminal therapy were reviewed retrospectively. Of 70 cases, 38 were treated by retrograde double-J stenting, 24 by minimally invasive percutaneous nephrotomy (MPCN) and 8 by antegrade double-J stenting.
RESULTS: All patients were followed up for an average of 12 months. The retrograde double-J stenting, MPCN and antegrade double-J stenting was successfully performed in 50.0% (19/38), 100.0% (24/24) and 62.5% (5/8), respectively. Technical failures in placing retrograde double-J stent were too difficult to identify the ureteric orifice (13/38) or failing to cross the obstruction site because of severe extraluminal compression (6/38). Failure in placing antegrade double-J stent was due to severe extraluminal compression (3/8). Dislodgment of nephrostomy tubes (11/19) was the major factor which limited the application of MPCN.
CONCLUSION: It is safe and effective to treat malignant ureteric obstruction with endourological technique, and suggested initially with retrograde double-J stenting. If malignant ureteric orifice occlusion or a severe extraluminal compression is showed in the imaging, MPCN or antegrade double-J stenting may be selected according to the site and the extent of obstruction.
