Abstract :

Introduction: Children with unilateral hydronephrosis underwent 99M TC-DMSA scan to evaluate if there is any difference between posterior calculation method and the geometric mean (GM) method for calculating %DRF (Differential Renal Function). Objective: The objective of this study is to evaluate the difference between posterior calculation method and the geometric mean (GM) method for calculating %DRF in 99M TC-DMSA scintigraphy. Method: 88 DMSA scans were studied from 2014 to 2015. Unilateral hydronephrosis kidney cases were selected for the study. The post %DRF was compared with the GM %DRF. The difference between the GM and post %DRF were calculated. Result: Among 88 patients, 30 patients have right hydronephrosis kidney while 58 have left hydronephrosis kidney. When the patients were analyzed by paired sample T-test, non-significant difference (P value > 0.05) was found in between post %DRF and GM %DRF. The mean post %DRF is 35.3�±15.2 and the mean GM %DRF is 36.1�±15.1. Conclusion: The conclusion of our study is that post %DRF processing of DMSA scan also gives the same %DRF as GM method is giving a minor mean difference.
