Insights
Extravesical ureteroplasty, a surgical technique, effectively treats primary vesicoureteral reflux in children. This minimally invasive approach shows a high success rate with low complication rates, making it a suitable option.
Area of Science:
- Pediatric Urology
- Surgical Techniques
- Renal Health
Background:
- Primary vesicoureteral reflux (VUR) is a common condition in children.
- Surgical intervention is sometimes necessary for persistent or complicated VUR.
- The Lich-Gregoir technique is an extravesical approach to ureteroplasty.
Purpose of the Study:
- To evaluate the efficacy and safety of the Lich-Gregoir extravesical ureteroplasty technique.
- To assess outcomes for children with primary extravesical reflux.
- To determine the success rate and complication profile of this surgical method.
Main Methods:
- Retrospective evaluation of 62 children undergoing extravesical ureteroplasty (Lich-Gregoir technique).
- Analysis of 82 refluxing renal units.
- Postoperative assessment using radiograms to detect persistent reflux or obstruction.
Main Results:
- A low rate of persistent reflux (6.1%) and obstruction (1.2%) was observed.
- Unilateral repair in cases of initially bilateral reflux led to resolution in the contralateral side in 6 out of 7 patients.
- A median hospitalization of 5 days was recorded.
Conclusions:
- Extravesical ureteroplasty (Lich-Gregoir technique) demonstrates a favorable success rate for uncomplicated primary VUR in children.
- The procedure is associated with low morbidity and a short hospital stay.
- This technique is a viable surgical option for pediatric VUR.
Abstract:
The results of extravesical ureteroplasty (Lich-Gregoir technique) for primary extravesical reflux in 62 children with 82 refluxing renal units are evaluated. Postoperative radiograms revealed persistent reflux in 5 (6.1 per cent) and obstruction in 1 (1.2 per cent) of the renal units. Of 7 patients in whom bilateral reflux had been noted previously but who had unilateral reflux at the time of operation, unilateral repair resulted in absence of reflux on the contralateral side in 6. The favorable success rate, low morbidity and median 5-day hospitalization support the use of extravesical ureteroplasty for uncomplicated reflux.
