Abstract:
OBJECTIVETo evaluate the endourological technique in the treatment of bilateral malignant ureteric obstruction.
METHODSThe 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.
RESULTSAll 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.
CONCLUSIONIt 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.
