Insights
Transvesicoscopic ureteric reimplantation is a safe and effective procedure for children with vesicoureteric reflux (VUR). This minimally invasive technique shows a high success rate, making it a viable surgical option.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Urologic Oncology
Background:
- Vesicoureteric reflux (VUR) is a common condition in children that can lead to kidney infections and damage.
- Traditional open ureteric reimplantation can be associated with significant morbidity.
- Transvesicoscopic approaches offer a less invasive alternative for managing VUR.
Purpose of the Study:
- To evaluate the safety and efficacy of transvesicoscopic ureteric reimplantation in pediatric patients.
- To assess the outcomes of the transvesicoscopic 'Cohen' ureteroneocystostomy technique.
Main Methods:
- Retrospective analysis of 17 ureteric units in 11 pediatric patients undergoing transvesicoscopic ureteroneocystostomy between 2003-2007.
- Patients included those with VUR and one with paraostial diverticula.
- Procedures included 6 bilateral and 5 unilateral reimplantations.
Main Results:
- The procedure was successfully completed in all patients with a 91% success rate (94% of ureters).
- Mean operative time was 217 minutes (unilateral) and 306 minutes (bilateral).
- Minor complications included pneumoperitoneum (2 cases) and transient hematuria (2 cases); one patient required longer hospitalization for UTI.
Conclusions:
- Transvesicoscopic cross-trigonal ureteroneocystostomy is a safe procedure in children.
- The technique demonstrates a high success rate for treating VUR and related conditions.
Purpose:
To evaluate the safety and efficacy of transvesicoscopic ureteric reimplantation in children.
Patients And Methods:
Seventeen ureteric units in 11 patients underwent a transvesicoscopic 'Cohen' ureteroneocystostomy in 2003-2007 and the results were retrospectively analyzed. There were four boys and seven girls. All patients had vesicoureteric reflux (VUR), except for one with paraostial diverticula. Six patients underwent bilateral and five unilateral transvesicoscopic reimplantation (a total of 17 units).
Results:
The procedure was successfully completed in all patients. Mean operation time was 217 min in unilateral cases and 306 min in bilateral cases without perioperative complications, except for pneumoperitoneum development in two cases. In the early postoperative period, two patients developed macroscopic hematuria. Mean hospital stay was 3.8 days (3-5 days), except for one patient who suffered from urinary tract infection and needed longer hospitalization. Mean follow-up period was 4.5 years (3-7 years). One patient with bilateral VUR had passive unilateral grade I VUR on postoperative cystogram, giving a success rate of 91% (94% of ureters). This patient was followed conservatively. One patient had recurrent urinary tract infections without reflux.
Conclusion:
Transvesicoscopic cross-trigonal ureteroneocystostomy can be safely performed with a high success rate in children.
