Insights
Retrograde intrarenal surgery is safe and effective for treating kidney stones in children under seven. This minimally invasive approach achieved an 88% stone-free rate with few complications in young patients.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Nephrolithiasis Management
Background:
- Pediatric kidney stones are challenging to treat, especially in young children.
- Limited data exists on the efficacy of retrograde intrarenal surgery (RIRS) in children under seven.
Purpose of the Study:
- To evaluate the safety and efficacy of RIRS for renal calculi in children younger than seven years.
- To present surgical outcomes and complication rates in this specific pediatric age group.
Main Methods:
- Retrospective review of 16 patients (17 procedures) under seven years old treated with RIRS.
- Flexible ureteroscopy and laser lithotripsy were utilized for all stone burdens.
- Data collected included stone characteristics, surgical details, stone-free status, and complications.
Main Results:
- An 88% stone-free rate was achieved after a mean follow-up of 10.3 months.
- Success rates were 100% for stones <10 mm and 81.8% for stones ≥10 mm.
- No major complications occurred; one case of ureteral perforation was managed conservatively.
Conclusions:
- Retrograde intrarenal surgery is a safe and effective treatment for pediatric renal calculi in children under seven.
- RIRS offers reasonable stone-free rates with minimal complications in this young population.
- This technique represents a viable option for managing intrarenal stones in pre-school-aged children.
Objectives:
The objectives of this study are to present our experience with retrograde intrarenal surgery for management of renal calculi in children less than 7 years old and to determine its safety and efficacy in this age group.
Methods:
Patient demographics, stone location and size, use of ureteral access sheath, stone-free status, complication rates, and follow-up were evaluated.
Results:
A total of 16 patients (9 boys and 7 girls; mean age, 4.2 years) underwent 17 procedures. The mean stone size was 11.5 mm (8-17 mm). Flexible ureteroscopy and laser lithotripsy were performed in all cases regardless of stone location. Dilation of the ureteral orifice was required in 5 cases (29.4%), and ureteral access sheaths were placed in 3 patients (17.6%). With a mean follow-up of 10.3 months, 88% of the children were stone free. The success rate for stones less than 10 mm was 100% and 81.8% for stones 10 mm or more (P < .05). There were no major complications, but there was 1 case of perforation and extravasation at the ureterovesical junction after balloon dilation that was managed with stent placement.
Conclusions:
Retrograde intrarenal surgery is a safe and effective method for the treatment of intrarenal calculi, and it achieves reasonable results with minimal complications in children less than 7 years old.
