An open ureterolysis is a surgical procedure aimed at addressing an obstructed ureter that has become entrapped by fibrous tissue in the retroperitoneum, a condition known as retroperitoneal fibrosis (RPF). Retroperitoneal fibrosis is a rare and complex condition characterized by chronic inflammation and the formation of fibrous tissue in the retroperitoneal space, which can lead to the obstruction of the ureters. This obstruction can result in significant complications, including kidney damage due to the buildup of urine. The procedure involves accessing the ureter through a flank incision, which allows the surgeon to mobilize surrounding structures, such as the colon, to gain adequate exposure to the affected ureter and retroperitoneal area. During the surgery, the extent of the fibrotic tissue is carefully evaluated, and the ureter is meticulously dissected free from the fibrous mass. In some cases, a biopsy of the fibrotic tissue may be performed for further analysis. Depending on the specific circumstances, the ureter may be divided, and the normal distal segment can be repositioned and reattached to the kidney, or it may be left intact and wrapped in omentum to promote healing and prevent further complications.
