Reconstruction of full-length ureter defects by laparoscopic bladder flap forming

To evaluate the safety and efficacy of laparoscopic bladder muscle flap reconstruction in the treatment of extensive ureteral avulsion. Patients with full-length (re length>20 cm) and upper ureteral (avulsion length>10 cm) defects were eligible. All patients were treated with laparoscopic bladder muscle flap reconstruction. Peri-operative information and post-operative complications were recorded. The kidney function, urinary ultrasound or computed tomography (CT), sun-renal function tests emission computed tomography (ECT) and cystography after operation were recorded. Ten patients were included (7 with full-length and 3 with upper ureteral defects). Median age was 56 years and 70% of them were female. The average operation time and blood loss was 124 min and 92.2 ml. There was no treatment-related adverse effects including urinary leakage, renal colic, fever, etc. The median follow-up was 18.5 months (3-39 months). The surgery did not significantly alter the renal function and separation degree of the renal pelvis during long-term follow-up. Double J stents were removed in nine patients (90%) within six months after operation. Only one case was diagnosed with post-operative anastomotic stricture, and subsequently received laparoscopic ipsilateral nephrectomy one year after the reconstruction operation. All cases had normal voiding and pear-shaped cystography. Laparoscopic bladder flap repair is a safe and effective treatment approach together with several advantages for patients with full-length or upper ureteral avulsion.

Automated summary

The study evaluated the safety and efficacy of laparoscopic bladder muscle flap reconstruction in treating extensive ureteral avulsion in 10 patients. Results showed that this surgical approach is safe and effective for patients with full-length or upper ureteral defects.
