Clinical efficacy of transcatheter arterial embolization in the treatment of intractable hematuria

Abstract

Objective To investigate the clinical effect of interventional embolization in the treatment of intractable hematuria after percutaneous nephrolithotripsy. Methods A retrospective analysis of the First Affiliated Hospital of Kunming Medical University from February 2014 to March 2016 after percutaneous nephrolithotomy appears intractable hematuria patients in 36 cases was conducted.All patients were treated with conservative treatment but invalid, then lesion was confirmed by renal artery angiography, after that, line embosphere microspheres or polyvinyl alcohol particles combined with spring ring interventional the treatment was conducted.Postoperative urine color changes, postoperative complications and follow-up were observed whether have bleeding again. Results (1)The success rate: 36 cases patients all with successful embolization, the symptoms of hematuria in 1-3 days gradually disappeared, and the effective rate was 100%.(2)Complications: the complications after operation in 10 patients appeared different degree of embolism syndrome, given analgesic and antiemetic, the symptoms gradually ease after treatment.One case patient with a transient increase of creatinine after operation, renal function returned to normal 7 days after the treatment.(3)Follow up: there was no recurrence of hemorrhage after 3-6 months of follow-up. Conclusion Transcatheter embolization in the treatment of intractable hematuria has definite curative effect, less trauma, high safety, less complications and faster postoperative recovery. Key words: Intractable hematuria; Super selective renal artery embolization
