How effective is ureteroscopy in the treatment of pediatric stone disease?

Abstract

Pediatric ureteroscopy has been increasingly used to manage both ureteral and renal stones. Unfortunately, there are no current standardized recommendations when treating pediatric stone disease so the modality chosen is left to the treating surgeon. A review of the current literature on pediatric ureteroscopy was used to compile this article. For the purposes of this review, the majority of series include stones ≤1 cm. Ureteroscopy is considered to be first-line therapy in treating mid- to distal ureteral stones and is rapidly evolving as an acceptable first-line therapy for renal stones as well. Limitations do exist and include stone composition, location, size, as well as the unique anatomic challenges faced by pediatric urologists in terms of anomalous kidneys and/or reconstructed urinary tracts. In conclusion, ureteroscopy can be considered first-line therapy for mid- or distal ureteral stones, however, it shares a similar efficacy rate as extracorporeal shock wave lithotripsy for the treatment of renal calculi. There is a need for direct comparison in the literature of all modalities treating pediatric stone disease to facilitate guidelines that help treating surgeons choose the most efficacious modality offering the highest success rates with the lowest morbidity.
