[Treatment with TAE of subcapsular hematoma as a complication of extracorporeal shock wave lithotripsy (ESWL): a case report]

Abstract

A 58-year-old man with a left renal stone and with poor controlled hypertension was attacked by sudden onset of left renal colic pain, gross hematuria and nausea at 3 hours after ESWL. Ultrasonography and enhanced computed tomography revealed severe subcapsular hematoma, which compressed the left kidney. Since serum hemoglobin level continued to decrease in spite of 7 days of conservative therapy, we performed transfusion of red blood cells and selective transarterial embolization (TAE). Renal angiography showed multiple pseudo-aneurysms of arteriole at the lower pole of the left kidney. Embolization of left renal artery was effective to relieve patient's symptom and to stabilize the serum hemoglobin level.
