SUPERSELECTIVE EMOLIZATION OF RENAL ARTERIES IN CASE OF IATROGENIC BLEEDING AFTER PERCUTANEOUS NEPHROLITHOTOMY

This paper aimed to assess the results of superselective embolization of renal vessels in patients with postoperative bleeding after percutaneous surgery for stone kidney disease. 1723 patients treated for percutaneous nephrolithotomy (PCNL) in urological clinic at I.M. Sechenov FMSMU up to 2015 were enrolled in the study. Hemorrhagic complications were observed in 83 (4.8%) patients, with 37 (2,1%) requiring blood transfusions. Superselective embolization of renal vessels was performed in 28 (1,6%) patients. In cases, when superselective embolization was not available, 2 patients (0,1%) underwent nephrectomy when bleeding occurred as a complication of PCNL. In all cases good clinical results were achieved with no need for open surgery. No complication after superselective embolization were observed. Superselective embolization is an effective, minimally-invasive method of neovascular diagnosis and treatment of bleeding, caused by iatrogenic arteriovenous kidney fistula. This technique allows to avoid organresecting surgery and eliminate dangerous complication.
