Description of intervention(s) / exposure
A total number of approximately 100 pregnant cases will be included in this prospective study. Subjects will be divided into 2 arms according to their urinary ultrasonographic findings between 24-36th week of their pregnancies. Pelvic-calyceal complex in millimeters from leading edge to leading edge, in two dimensions less than 5mm will be included in control arm, whereas dimensions between 5-15mm will be included in study arm as mild hydronephrosis cases. Urinary neutrophil gelatinase-associated lipocalin (NGAL) excretion and other renal functions will be determined on the day of ultrasonography.

Comparator / control treatment
Control group will be consisted of pregnants without identified hydronephrosis with ultrasonography.

POWER ANALYSIS:
Group sample sizes of 43 and 43 achieve 90% power to detect a difference of -50.0 between the
null hypothesis that both group means are 50.0 and the alternative hypothesis that the mean of
group 2 is 100.0 with known group standard deviations of 50.0 and 100.0 and with a significance
level (alpha) of 0.05000 using a one-sided two-sample t-test.
In conclusion, 43 patiens will be allocated for each group.
