Laparoscopic nephroureterectomy complicated by rupture of adrenal artery pseudoaneurysm.

We present a case of ruptured adrenal artery pseudoaneurysm as a complication of laparoscopic nephroureterectomy. An 87-year-old woman with hematuria and transitional cell carcinoma on imaging underwent laparoscopic nephroureterectomy. Her postoperative recovery was uneventful until day 17, when she presented with severe abdominal pain, syncope, and significant anemia. An aneurysm was suspected on computed tomography and Doppler ultrasonography. Selective angiography showed a pseudoaneurysm of the adrenal artery that could not be successfully embolized. Exploratory laparotomy obtained hemostasis, and the pseudoaneurysm was identified as involving an adrenal artery next to a surgical clip, which is speculated to be the cause.
