ABSTRACT

Background. The spontaneous perirenal hematoma is uncommon and the etiology is diverse. The most common causes are renal tumors and vascular abnormalities. Clinical features include hematuria, abdominal pain and, in some cases hemodynamic instability. CT scan is the diagnostic procedure of choice; angiography can be a complementary diagnostic and a therapeutic procedure. Case 1. 38-year-old woman with 33-week pregnancy, lumbar pain and CT scan showing bilateral perirenal hematoma. She received conservative management, 6 months later presented reduction of right hematoma, and persistence on left kidney, which was punctured successfully. Case 2. 38-year-old man with abdominal pain in upper right quadrant and microscopic hematuria. CT scan showed a right renal tumor and a defect in bladder filling. Cystoscopy showed a vesical tumor in the right ureteral meatus. Hystopatological study revealed a high-grade transitional cell carcinoma; the patient underwent a right nephroureterectomy. Case 3. 33 year-old male, with abdominal pain, nausea and vomiting, who was taken to a laparotomy, finding a left retroperitoneal hematoma, which was drained. A month later he presented with abdominal pain, anemia, gastric plenitude and vomiting. CT scan revealed a left perirenal hematoma, which was surgically evacuated.
