Different approaches among physicians to treat pediatric stone disease: a survey-based study

Introduction. Pediatricians, surgeons and subspecialties as pediatric urology and nephrology are involved in the diagnosis and treatment of pediatric renal stone disease (RSD). The aim of this study was to determine diagnostic and treatment approaches, of different disciplines, and to assess differences in their routine diagnostic and treatment protocols. Population and methods. A questionnaire was designed and administered to the participants of the RSD sessions in national congresses of all disciplines in 2017 to evaluate the diagnostic and treatment routines of specialties (surgeons and pediatricians) and subspecialties (pediatric nephrologists and pediatric urologists) for RSD. Results. A total, of 324 questionnaires were analyzed, from 88 pediatricians (27 %), 121 urologists (37 %), 23 pediatric surgeons (7 %), 54 pediatric nephrologists (17 %), and 38 pediatric urologists (12 %). Both groups agreed on the necessity of metabolic evaluation. For distal ureter stones that were >= 6 mm; surgeons preferred ureteroscopy (URS), pediatricians preferred shock wave lithotripsy (SWL) (p < 0.001) and subspecialties preferred URS for the treatment (p = 0.636). For lower calix stones less than 1 cm surgeons and subspecialists preferred SWL, while pediatricians preferred hydration (p < 0.001, p = 0.371). For the stone between 1.1 and 2 cm, surgeons preferred intrarenal surgery (RIRS) and SWL, pediatricians preferred SWL (p = 0.001). For larger stones, surgeons and subspecialists preferred percutaneous nephrolithotomy (PCNL), and pediatricians preferred SWL (p = 0.458 p = 0.001). Pediatric urologist chose low-dose computerized tomography as a diagnostic radiologic evaluation (p = 0.029). Conclusion. There are differences between the disciplines who take an active role in diagnosis and treatment of RSD.
