Combination of Extracorporeal Shockwave Lithotripsy and Ureteroscopy for Large Staghorn Calculi in a Pediatric Patient: Case Report.

ABSTRACT

Background: Extracorporeal shockwave lithotripsy (SWL) is a procedure commonly performed to treat nephrolithiasis, with promising results in pediatric patients. However, increasing renal calculi size is directly related to worsening stone-free rates. There are few reports in the literature of >2-cm staghorn calculi that expound on the exact mechanism of treatment in the pediatric population. Case Presentation We present a case report of a 3-year-old boy who presented with a large 3-cm staghorn calculi effectively treated with one session of SWL followed by a planned staged ureteroscopy for definitive treatment. Conclusion: Despite the numerous studies limiting the use of SWL to treat stones <2 cm, if used in softer composition stones, coupled with the larger focal volume involved with smaller patients, SWL when used in combination with adjunctive ureteroscopy is a safe and effective treatment option.
