To evaluate the clinical utility of pre-renal transplant LUT investigations in pediatric populations after their referral for transplant evaluation based on the etiology of their ESRD. A 16 year retrospective review of patients undergoing RT performed at our institution was performed. Patients were stratified into two groups: Group 1-non-urologic and Group 2-urologic etiology for ESRD. Baseline characteristics, pre-transplant LUT investigations, and urologic interventions were assessed. One-year clinical outcomes were compared between those with and without LUT investigations following referral for renal transplantation (RT). 227 patients and 97 patients were identified for Groups 1 and 2, respectively. 19% of Group 1 and 73% of Group 2 had VCUG, while 1% and 13%, respectively, had UDS ordered following referral for RT. In both groups, >50% of VCUG and UDS were ordered without specific clinical concerns. These had low likelihood of prompting interventions, both pre-transplant (Group 1-VCUG 0%, UDS 0%; Group 2-VCUG 0%, UDS 8%) or post-transplant (Group 1-0%, Group 2-5%). In both groups, LUT investigation following referral for RT did not lead to differences in 1 year outcomes assessed. In anticipation of pediatric RT, LUT investigations ordered without clinical indications did not provide information that altered management prior to transplantation.
