Iatrogenic rupture of the ureter during kidney biopsy.

Perirenal hematoma, hematuria, and abdominal pain are common complications of kidney biopsy, but ureter rupture is relatively less frequent. Here we report a patient who experienced severe abdominal pain and gross hematuria following a non-smooth procedure of ultrasound-guided kidney biopsy. Computed tomography showed rupture of the left upper third of the ureter. We implanted a curled double-J catheter between the renal pelvis and urinary bladder. Abdominal pain and gross hematuria improved. After 2 months, the double-J catheter was removed and the patient had no further clinical symptoms. The possibility of ureter rupture, although rare, should be considered in the presence of abdominal pain and gross hematuria in patients after receiving a kidney biopsy.
