Ureteral repair using buccal mucosa is a procedure in which the ureter is expanded in the area of a scar-related narrowing (stricture) using a piece of buccal mucosa to restore urine flow.

In about three-quarters of the cases, this narrowing results from medical procedures or previous radiation.

Affected patients often suffer from flank pain due to urinary retention and discomfort during urination. Other possible consequences include recurring urinary tract infections, stone formation, chronic kidney failure, and in the worst case, loss of kidney function.

This method is suitable for reconstructing the middle or upper sections of the ureter, requires a functional kidney, and harvesting of buccal mucosa. Limitations may exist in cases of oral mucosal diseases and in patients with professions involving wind instruments.

The Da-Vinci ureteral repair using buccal mucosa is a robot-assisted, minimally invasive keyhole surgery that requires special surgical expertise. Instruments are introduced under general anesthesia through small abdominal incisions and then controlled by the surgeon via a console.

First, a piece of mucosa is harvested from the oral cavity. Then, the narrowed section of the ureter is slit open, and the buccal mucosa piece is sutured onto it to expand the lumen of the ureter. Subsequently, an internal ureteral and bladder catheter are inserted for healing.

The success of the operation depends on the team’s experience and specific patient data.

Every surgery carries certain risks, such as bleeding during or after the operation, damage to adjacent organs, or wound healing problems.

Previous surgeries, illnesses, or medications can affect the course of the operation and postoperative recovery. These risks are assessed individually based on the patient’s medical history.

In the oral area, swelling, sensory disturbances, or scarring can occur, as well as temporary difficulties in speaking or eating. In the ureteral area, possible side effects include urinary retention, urine leakage, scar formation, inflammations, and urinary tract infections.

The operation aims at restoring normal urine flow; therefore, continuous monitoring of the kidneys is essential. A balanced diet, adequate fluid intake, exercise, and sleep support recovery and strengthen long-term health.
