Insights
Pneumovesicoscopic cross-trigonal ureteral reimplantation is a safe and effective minimally invasive technique for treating primary vesicoureteral reflux (VUR) in children. This procedure successfully resolved VUR in 13 of 14 pediatric patients.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Urologic Oncology
Background:
- Primary vesicoureteral reflux (VUR) is a common congenital anomaly in children.
- Surgical intervention is indicated for persistent or high-grade VUR to prevent renal scarring and damage.
- Traditional open reimplantation can be associated with significant morbidity.
Purpose of the Study:
- To evaluate the safety and efficacy of pneumovesicoscopic cross-trigonal ureteral reimplantation for primary VUR in children.
- To assess the outcomes and complication rates of this minimally invasive approach.
Main Methods:
- A cohort of 14 children (aged 4-12 years) with VUR grade III or higher underwent pneumovesicoscopic Cohen's cross-trigonal reimplantation.
- The procedure involved cystoscopic guidance, trocar insertion, ureteral mobilization, submucosal tunnel creation, and ureteroneocystomy with absorbable sutures.
- Postoperative follow-up included renal ultrasound, voiding cystourethrogram, and MAG3 scans.
Main Results:
- The study included 14 children with 19 refluxing ureters.
- Reflux resolution was achieved in 13 out of 14 patients (93%) within 3-6 months postoperatively.
- The mean operating time was 136 minutes, with no conversions to open surgery required. Mild suprapubic emphysema occurred in one patient.
Conclusions:
- Pneumovesicoscopic cross-trigonal ureteral reimplantation is a safe and effective minimally invasive surgical option for pediatric VUR.
- This technique offers successful VUR correction with low complication rates.
- Further studies may explore long-term outcomes and comparisons with other minimally invasive methods.
Aim:
We report our experience with pneumovesicoscopic cross-trigonal ureteral reimplantation to correct primary vesicoureteral reflux (VUR) in children.
Material And Methods:
14 children (10 girls, 4 boys, aged 4 to 12 years) with persistent VUR ≥ grade III (5 bilateral, 19 refluxing ureters) underwent pneumovesicoscopic Cohen's cross-trigonal reimplantation. Under cystoscopic control, a first midline 5-mm trocar was introduced for a 0°\30° telescope at the dome of the bladder, and 2 left and right 3- or 5-mm trocars were inserted through the anterolateral wall. The ureter was freed by creating a sharp plane between the detrusor muscle and the ureteral wall. If necessary, the ureter was tailored outside the bladder. Submucosal tunnel(s) were prepared with the help of scissors and graspers. The detrusor at the site of the ureter mobilization was repaired and ureteroneocystomy was performed using 4-5 interrupted absorbable sutures. A 12-Ch Foley catheter was introduced at the site of the dome port. The urethral and suprapubic catheters were removed 2-3 days after the procedure and the patients were discharged on day 3.
Results:
One boy developed mild suprapubic emphysema postoperatively. Mean operating time was 136 min (range 80-230 min). No patient required conversion to the open technique. Renal US, VCUG, and MAG3 radionuclide scans were obtained in all patients between 3-6 months postoperatively, and provided evidence of reflux resolution in 13 out of 14 patients.
Conclusion:
Our experience seems to confirm that pneumovesicoscopic cross-trigonal ureteral reimplantation can be performed safely and effectively.
