Objectives To present the radiological and clinical results of transcatheter arterial embolization in patients with active bleeding after percutaneous renal procedures. Methods A total of 79 consecutive patients who underwent angiography for percutaneous renal procedure‐related bleeding were included in the present retrospective analysis. Patient characteristics, angiographic management and clinical outcomes were analyzed. Results On angiography, bleeding foci were observed in 81.0% of the patients (64/79), all of whom underwent transcatheter arterial embolization. Among the 15 patients (19.0%) with negative angiographic findings, empirical transcatheter arterial embolization was carried out in six patients (40.0%). The technical success rate in 64 patients with positive angiographic findings was 100%, and the clinical success rate in 70 patients who underwent transcatheter arterial embolization was 85.7% (60/70). A total of 14.3% (10/70) of patients with clinical failure underwent repeat transcatheter arterial embolization and all achieved clinical recovery. There were no major complications. There was no statistical difference in estimated glomerular filtration rate values before the percutaneous renal procedure and those measured 7 days after transcatheter arterial embolization (43.4 ± 24.4 to 44.6 ± 25.1 mL /min/1.73 m 2 ; P = 0.189). Clinical failure was not associated with age, sex, type of renal procedures, bleeding tendency, presence of active bleeding on angiography, latency time and embolic agents used ( P > 0.05). Conclusions Transcatheter arterial embolization is a safe and effective method of treating percutaneous renal procedure‐related bleeding without renal function deterioration.
