Abstract
Purpose
In order to anatomically reconstruct the ureteral stenosis, we present a novel technique for laparoscopic ureteral reimplantation.
Patients and methods
Three young females, who were diagnosed as hydroureteronephrosis caused by congenital vesicoureteral junction obstruction, were treated by laparoscopic ureteral reimplantation with a tunnel underneath the broad ligament.
Results
Surgery was performed successfully without conversion to open surgery. No major intraoperative or postoperative complications occurred. The mean postoperative follow-up was 38, 33 and 26 months respectively. The operative time was between 220 and 260 minutes. The mean estimated blood loss was less than 20 mL. Subsequent imaging performed 3 months after surgery revealed relief of hydroureteronephrosis for all patients. Patients all gave birth to healthy neonates and showed normal urinary tract sonogram and urine analysis during gestation period.
Conclusion
Laparoscopic ureteral reimplantation with a tunnel underneath the broad ligament tunnel is safe, effective, allowing for anatomical reconstruction of ureter defects, however. A larger clinical sample and longer follow-up period will be needed for fully validation of this technique.
