Dynamic Renal Scintigraphy Results of Pediatric Patients Operated Due to Unilateral Ureteropelvic Junction Obstruction: A Novel Approach to Overestimated Ipsilateral Differentiated Renal Function

Objective: The aim of this study was to scintigraphically investigate the preoperative and postoperative renal functions patients operated due ureteropelvic junction obstruction, discuss factors affecting indication surgery emphasize important points consider during scintigraphic examination. Method: We retrospectively analyzed pediatric cases who underwent pyeloplasty obstruction. Patients for primary obstruction whose dynamic scintigraphy results could be obtained were included in study. divided into two groups as those with <50% ≥50% ipsilateral differentiated function. difference between considered statistically significant when p<0.05. Results: median ages 36 DRF group 24 7.7 months 8.5 months, respectively. mean function values main significantly different from each other both periods. changes within also analyzed, yielding differences. Ipsilateral on a general, subgroup basis, ultrasound findings kidney subgroups revealed. Conclusion: Increased hydronephrosis degree pelvis anterior-posterior diameter are closely related overestimated For deciding ureteral examinations make sense help US clinical condition patient.
