This study shows laparoscopic Boari flap surgery offers successful short and long-term outcomes for distal ureteral reconstruction. The minimally invasive technique demonstrated a high success rate with minimal complications in 30 patients.

Area of Science:

Urology
Minimally Invasive Surgery
Reconstructive Surgery

Background:

Distal ureteral injuries present a reconstructive challenge.
The Boari flap is a recognized technique for ureteral repair.
Laparoscopic approaches to the Boari flap are less frequently reported, particularly long-term outcomes.

Purpose of the Study:

To evaluate the efficacy and safety of laparoscopic intracorporeal Boari flap for distal ureteral reconstruction.
To present the multi-institutional experience and long-term results of this technique.

Main Methods:

A multi-institutional retrospective analysis of 30 patients undergoing laparoscopic intracorporeal Boari flap.
Standardized surgical technique across three Latin American centers.
Prospective data collection and retrospective analysis of outcomes.

Main Results:

The mean patient age was 43.2 years; 73.3% were female.
Common etiologies included hysterectomy (46.6%) and ureterolithotomy (30%).
The procedure had a 96.6% success rate with a mean follow-up of 32 months, low complication rates (16.6%), and no conversions to open surgery.

Conclusions:

Laparoscopic Boari flap demonstrates favorable short- and long-term outcomes for distal ureteral reconstruction.
This minimally invasive technique is safe and effective in experienced hands.
Further research can support wider adoption of this approach.
