Insights
Endoscopic treatment for vesicoureteric reflux (VUR) using dextranomer instillation is a safe and effective option for children, offering better outcomes than conservative management. This minimally invasive approach shows a high success rate with few complications.
Area of Science:
- Urology
- Pediatric Surgery
- Minimally Invasive Procedures
Context:
- Vesicoureteric reflux (VUR) affects children, potentially leading to kidney infections and damage.
- Conservative management has limited success rates for moderate to severe VUR.
- Endoscopic treatment offers a less invasive alternative to open surgery.
Purpose:
- To compare the efficacy of endoscopic dextranomer (Dx/Ha) instillation versus conservative treatment for VUR in children.
- To evaluate the success rates and complication profiles of both treatment modalities.
- To assess long-term outcomes of VUR treatment in pediatric patients.
Summary:
- A prospective randomized study compared endoscopic Dx/Ha instillation (22 children) with conservative management (22 children) for VUR grades 3-5.
- The endoscopic group achieved a cure rate of 54.5% and improvement in 66.7% of cases.
- The conservative group showed a cure rate of 22.7% and improvement in 18.2% of cases, with significantly lower success rates.
Impact:
- Endoscopic dextranomer instillation is a safe and effective treatment for pediatric VUR across all age groups.
- This minimally invasive procedure yields good therapeutic outcomes with minimal adverse effects.
- The findings support endoscopic treatment as a preferred option for VUR, potentially reducing long-term renal complications.
Background:
The aim of study is to evaluate the results of endoscopic treatment of vesicoureteric reflux (VUR) comparing with conservative mode.
Methods And Results:
In the years 2003-2006 there were forty for children in prospective randomised study enrolled and divided into two groups. Twenty two children 1-40 months old (22.9 months) were operated. Dx/Ha (Deflux) was instilled for VUR grade 3-5. The results of treatment were compared with outcome of twenty two conservatively treated randomly assigned children aged 1-32 months (mean age 13.5 months) Postoperative videourodynamic study was used to evaluate for the presence of VUR and function of the bladder and ultrasound investigation was performed too (exclusion of obstructive megaureter in operated group). There were 22 children controled after instillation. The children were followed 11-24 months. VUR was cured in 12 cases (54.5%) and improved (grade 1-2) in 5 children (66.7%). All children absolved treatment without any complications, excluding one case with obstructive megaureter after pyelonephritis diagnosed. There were 22 children evaluated in conservative group. Five children were cured (22.7%) and VUR was improved (grade 1-2) in four (18.2%)
Conclusions:
Endoscopic miniinvasive instillation of dextranomer is safe and effective treatment of VUR in all age groups with good therapeutical outcome and minimum of adverse effects.
