Diagnosis and treatment of renal hemorrhage via angiography and transcatheter embolization

Objective: To evaluate the clinical value of diagnosis and treatment of renal hemorrhage via angiography and transcatheter embolization. Methods: Sixty two patients with renal hemorrhage, including 28 cases of renal carcinoma, 13 of renal angiomyolipoma, 12 of renal trauma, 7 of renal vascular malformation and 2 patients of renal aneurysm. All patients had the symptoms of gross hematuria and diagnosed by selective angiography for localization and blood supply, and followed by infusing medicine or/and embolization with various embolic materials through seldinger method. Results: All patients had obtained correct diagnosis for localization, extent, degree, causes and blood supply of the renal hemorrhage through angiography and contrast medium extravasation was observed in 19 cases. Gross hematuria ceased in 43 patients after 12 hours, 17 patients after 24 hours of interventional therapy respectively. Gross hematuria relieved obviously and ceased after 1 week in 2 renal carcinoma patients. No recurrent renal hemorrhage except 4 renal carcinoma patients occurred after 1 month of therapy. During 1-48 months follow up, the satisfactory embolization effect was observed through CT. Conclusions: Transcatheter angiography and embolization is reliable and effective in diagnosis and treatment of renal hemorrhage with less invasion and complications and furthermore with preservation of renal function to the utmost.
