Safety and efficacy of transcatheter arterial embolization in autosomal dominant polycystic kidney patients with gross hematuria: Six case reports.

Background: To retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating autosomal dominant polycystic kidney disease (ADPKD) patients with gross hematuria.

Case Summary: The purpose of this study is to retrospectively report the safety and efficacy of renal transcatheter arterial embolization for treating ADPKD patients with gross hematuria. Materials and methods: During the period from January 2018 to December 2019, renal transcatheter arterial embolization was carried out on 6 patients with polycystic kidneys and gross hematuria. Renal arteriography was performed first, and then we determined the location of the hemorrhage and performed embolization under digital subtraction angiography monitoring. Improvements in routine blood test results, routine urine test results, urine color and postoperative reactions were observed and analyzed. Results: Renal transcatheter arterial embolization was successfully conducted in 6 patients. The indices of 5 patients and the color of gross hematuria improved after surgery compared with before surgery. No severe complication reactions occurred.

Conclusion: For autosomal dominant polycystic kidney syndrome patients with gross hematuria, transcatheter arterial embolization was safe and effective.
