Pyelocaliectasis and intrarenal artery Doppler indices in uncomplicated pregnancies

The effect of pyelocaliectasis on intrarenal arterial Doppler indices was e valuated in healthy pregnant women with respect to nonpregnant controls. Th ere was no significant difference between the pregnant and nonpregnant subj ects regarding the systolodiastolic ratio, resistivity index and pulsatilit y index throughout the second and third trimesters (p for all > 0.05). Ther e were 134 kidneys with grade 0, 38 kidneys with grade I and 24 cases with grade II pyelocaliectasis in the pregnant population. Grade II caliectasis was found only in the right kidneys. The nonpregnant women all had grade 0 caliectasis. Doppler indices were not significantly different in various gr ades of caliectasis, and right and left kidneys had similar Doppler indices . The results of this study suggest that pyelocaliectasis increases with ad vancing gestational age and is more frequent and prominent on the right sid e but has no effect on intrarenal Doppler indices in healthy pregnant women . In cases of prominent alterations in Doppler indices, renal pathological conditions should be sought.
