Introduction: To compare endourology versus pediatric urology exposure to pediatric stone cases during fellowship, comfortability in treating pediatric stone cases, and access to pediatric surgical equipment.
Materials and methods: A survey was distributed to all pediatric urology fellowship programs and the Endourological Society. Age was stratified into < 12 months old, 12 months-4 years, 5-12 years, and 13-18 years. Exposure and comfortability performing extracorporeal shock wave lithotripsy (SWL), ureteroscopy (URS) and percutaneous nephrolithotomy (PCNL) were assessed across age groups. Exposure was assessed as 'yes/no' and comfortability was scaled from 1-5 ('would not do' to 'very comfortable').
Results: Seventy-two surveys met inclusion criteria, with 23 (31.9%) from pediatric urologists and 49 (68.1%) by endourologists. During fellowship, pediatric urologists had more exposure to SWL in toddlers (p = 0.03) and school age children (p = 0.045), URS in toddlers (p = 0.012) and school age children (p = 0.002), and PCNL in infants (p = 0.031) and school age children (p = 0.025) compared to endourologists. Pediatric urologists were significantly more comfortable performing SWL in toddlers (p = 0.04), URS in toddlers (p = 0.04) and school age children (p = 0.04), and PCNL in school age children (p = 0.02) compared to endourologists. Endourologists were significantly more uncomfortable than pediatric urologists in performing URS in toddlers (p = 0.03) and PCNL in infants (p = 0.04) and school age children (p = 0.03). There were no differences in availability of pediatric equipment.
Conclusions: Pediatric urologists, have significantly more exposure than endourologists during fellowship and are more comfortable performing surgical treatment for urolithiasis in most pediatric ages. Endourology fellowships may benefit from greater exposure to pediatric patients with stones.
