“…The reasons for the incorrect prenatal diagnosis in approximately one-third of fetuses with urinary tract abnormalities in our study and that of Helin and Persson [1] are not clear. The limitation of available ultrasonographic techniques, reports by different ultrasonographers (although our studies were performed by one ultrasonographer) or inaccurately reported gestational ages may have played a role in the incorrect diagnoses.…”

“…The prenatal diagnoses and respective postnatal findings of these patients are presented in Table 1 Discussion Congenital abnormalities of the urinary tract occur in 3.3%-11.1% of autopsies [3][4][5][6][7] and account for about 50% of ultrasonographically diagnosed congenital malformations [1]. These abnormalities may lead to obstruction (which may interfere with renal development and function), infection, and renal failure.…”

“…It can also detect congenital abnormalities of the urinary tract as early as 16 weeks' gestation [1,2]. With the advent of fetal surgery and other prenatal methods of treating these congenital abnormalities, it becomes imperative to evaluate the reliability of these prenatal diagnostic techniques.…”

To investigate the ability of ultrasonography to detect urinary tract abnormalities prenatally, we reviewed the records of 26 pregnancies diagnosed by prenatal ultrasound to have urinary tract anomalies. We compared the prenatal diagnoses with postnatal renal and urinary tract pathology. This comparison showed different degrees of agreement for different prenatal diagnoses (2 individuals had more than one diagnosis): 4 of 8 for multicystic kideys, 1 of 1 for polycystic kidney disease, 1 of 2 for renal agenesis, 6 of 7 for ureteropelvic junction obstruction, 1 of 3 for posterior urethral valves, 4 of 5 for no pathology noted, and 2 of 2 for other abnormalities. Prenatal diagnosis and postnatal findings were in agreement in 68% of cases. Varying levels of diagnostic reliability should be considered when managing pregnancies complicated by fetal urinary tract abnormalities and subsequent postnatal evaluation and diagnosis. Further efforts are needed to improve on the techniques and reliability of prenatal diagnosis of urinary tract abnormalities.

“…The advent of routine antenatal ultrasonography enables urinary tract abnormalities to be identified as early as 12-14 weeks of gestation [1,2]. Maternal ultrasonography detects fetal hydronephrosis, leading to the diagnosis of PUJ obstruction postnatally in 0.2-0.4% of cases [1][2][3][4][5]; PUJ obstruction requires surgery in 15-30% of affected children [6][7][8][9][10][11][12][13][14].…”
