Aim To evaluate the role of doppler ultrasonographorin managing hydronephrosis during pregnancy. Methods The study included 27 pregnant patients with unilateral symptomatic persistent hydronephrosis (group 1) and 38 pregnant patients with physiological hydronephrosis of pregnancy (group 2). All pregnant patients underwent Doppler Ultrasonography to determine the Resistive Index (RI) and the difference between the RI of the corresponding and contralateral kidney (Delta Resistive Index = ?RI). Results There were no statistical differences between the two groups in terms of age, mean gestational period, or number of pregnancies. The mean renal RI of the hydronephrosis side was 0.68±0.05 in group 1 and 0.60±0.05 in group 2 (p<0.001). The mean ?RI of group 1 was significantly higher than the mean ?RI of group 2 (0.07±0.03 versus 0.02±0.01, respectively, p<0.001). The RI and ?RI were considered positive with values of ?0.70 and ?0.04, respectively, and the RI was sensitive in 44.4% and specific in 92.1% for intervention treatment. The corresponding values for ?RI were 88.9% and 89.5%. The positive predictive value and negative predictive value of ?RI for intervention were 85.7% and 91.9%, respectively. Conclusion It is much better to consider ?RI than RI when deciding on interventional treatment in hydronephrosis during pregnancy.
