Retrograde intrarenal surgery (RIRS) is a safe and effective treatment for pediatric urolithiasis, showing improved stone-free rates and decreased complications with increased surgeon experience. Further research is needed to optimize its use across all pediatric age groups.
Area of Science:
- Pediatric Urology
- Minimally Invasive Surgery
- Urolithiasis Management
Background:
- Pediatric urolithiasis incidence is rising, necessitating advanced treatment options.
- Retrograde intrarenal surgery (RIRS) offers a minimally invasive approach via natural orifices, avoiding percutaneous access morbidity.
- This review examines RIRS evolution in children, focusing on age-related anatomical impacts on outcomes.
Approach:
- A comprehensive literature search was conducted from inception to October 2021 across major databases (PubMed, EMBASE, Web of Science).
- 51 relevant articles were selected after screening 2022 initial records and 165 full-text articles.
- Two pediatric urologists synthesized findings on RIRS development and pediatric application.
Key Points:
- RIRS is now a preferred modality for pediatric urolithiasis over extracorporeal shockwave lithotripsy.
- Passive dilation reduces the need for active ureteral dilation, though prestenting necessity remains unclear.
- Ureteral access sheath use is common, but long-term effects on pediatric growth require investigation.
Conclusions:
- RIRS has significantly improved stone-free rates (SFR) and reduced complications in pediatric patients.
- Increased surgeon experience correlates with better RIRS outcomes.
- Further research and larger datasets are essential to establish RIRS as the definitive treatment for all pediatric renal stone cases.
