Abstract:
Objective To evaluate the clinical value of percutaneous renal artery angiography and embolization of the renal artery pseudoaneurysms. Methods A retrospective analysis was made on 15 cases of postoperative urethral bleeding following urinary calculi surgery from January 2012 to February 2014, which were diagnosed of renal artery pseudoaneurysms via the renal artery angiography.Superselective catheter placement was carried out into the proximal of parent artery and the pseudoaneurysm was embolized by using a coil and gelatin sponge. Results Renal artery angiography clearly displayed pseudoaneurysms in the 15 cases, which were located in interlobular artery in 11 cases, arcuate artery in 3 cases, and minor interlobular artery in 1 case.Urethral bleeding was stopped after using gelatin sponge and spring coil embolization.Among them urethral bleeding recurred in 1 case after two days, and a second embolization was conducted.After the embolization, transient renal colic happened in 2 cases and a fever of 37.8-39.3 ℃lasting for 3-8 d was seen in 7 cases.Follow-ups for 3-24 months ( mean, 15 months) showed no renal dysfunction and urinary tract bleeding. Conclusion The transcatheter embolization and angiography can diagnose and treat renal artery pseudoaneurysms, with safe and effective outcomes.
