    Resistance index in fetal interlobar renal artery with renal pelvic dilatation up to 10 mm

    JOURNAL OF CLINICAL ULTRASOUND, Issue 2 2003

    Abstract Purpose The purpose of this study was to compare the resistance indices (RIs) in the fetal interlobar renal arteries (IRAs) of third-trimester fetuses with or without pelvicaliceal dilatation of up to 10 mm and to compare them with those of the full-term healthy infants. Methods Women with uncomplicated, low-risk, singleton third-trimester pregnancies were examined sonographically. The RIs in the IRAs were measured in the fetuses, who were stratified into 3 groups according to the anteroposterior diameter of the renal pelvic dilatation: group I, no dilatation; group II, 1,5-mm dilatation, and group III, 6,10-mm dilatation. Results In total, 178 women were examined. We could study both kidneys in 139 of the fetuses; in the other 39, only 1 kidney could be imaged perfectly. This yielded a total of 317 kidneys. Group I fetuses included 172 (54%); group II, 98 (31%); and group III, 47 (15%) of the kidneys. The mean (± standard deviation) RIs in the IRAs were 0.81 ± 0.09, 0.80 ± 0.07, and 0.80 ± 0.06 in the 3 groups, respectively, with no statistically significant difference between the groups (p = 0.72). There was also no statistically significant difference between the RIs recorded in the right and left kidneys. The mean RI in the IRAs of the 34 infants who were available for follow-up 6,12 weeks after delivery was 0.73 ± 0.07, which was significantly less than that recorded in the third-trimester fetuses (p = 0.005). Conclusions The RI in the fetal IRA does not differ in fetuses with and without renal pelvic dilatation of up to 10 mm. Thus, an increase in the RI or an RI that significantly differs between the right and left kidneys should be investigated further for possible renal pathology. © 2003 Wiley Periodicals, Inc.

    Isolated minimal renal pelvic dilatation detected antenatally in a non-tertiary setting is an uncommon predictor of significant vesicoureteric reflux

    Objectives: To study in a non-tertiary centre the prevalence and grade of vesicoureteric reflux detected postnatally in infants already identified antenatally with isolated minimal renal pelvic dilatation. Methods: Retrospective review over the years 1998,2000 inclusive of a central computerized database in the single paediatric practice within Albury Wodonga. Results: Ninety-three (65 male) infants detected antenatally with isolated renal pelvic dilatation (,3 mm at 18 weeks gestation, ,5 mm at 32 weeks gestation,<10 mm dilatation at any gestation) had a Micturating Cystourethrogram result. Thirteen infants (seven male) had vesicoureteric reflux detected, with a total of 18 refluxing renal units. Of these 13 infants five had bilateral vesicoureteric reflux (two male), and eight had unilateral vesicoureteric reflux. The median reflux grade was 2.0, with significant vesicoureteric reflux (greater than grade II) occurring in 5.4% (5/93). Conclusions: Significant vesicoureteric reflux (greater than grade II) occurred in only 5.4% (5/93) of infants. It is concluded that isolated minimal renal pelvic dilatation detected antenatally is a poor screening test for clinically significant vesicoureteric reflux. [source]
