Bilateral herniation of renal pelves: a complication of cutaneous pyelostomy

The first reported case of bilateral herniations of the renal pelves as a complication of cutaneous pyelostomy is presented. We describe a modification of the original surgical technique that may prevent herniation, based on fixation of the pelvis to the lumbodorsal fascia as well as the cut edge of the pelvis to the skin. In our patient the bilateral herniations were corrected by repairing the fascial defects and suturing of the pelvis to the fascia.
