[Bilateral ureteral obstruction secondary to aneurysm of abdominal aorta: a case report].
A 66-year-old man with the chief complaint of oliguria had been referred to our hospital under the diagnosis of bilateral hydronephrosis and abdominal aortic aneurysm by his family doctor. CT scan and digital subtraction angiography demonstrated an abdominal aortic aneurysm continuing to bilateral internal iliac arteries. The degree of right hydronephrosis was less advanced compared to the left side. Right percutaneous nephrostomy was performed because the retrograde stenting was unsuccessful. After the renal function improved, an operation for the aneurysm was undertaken in the surgical department. Although bilateral ureterolysis was possible, the resection of the aneurysm could not be done. After clamping the nephrostomy catheter, drainage of urine into the ureter was not seen one month after the operation. A double-J ureteral stent was inserted by the antegrade approach and the nephrostomy tube was removed. By exchanging the stent every 3 months, the renal function has been stable and the size of the aneurysm unchanged during the 25 months after the surgery.
