“…Analysis of the literature [8,16,26,30,44,57,58,70,78,80,86,103,105,110,113] shows that no large series of hydronephrosis with prenatal diagnosis has been published to our knowledge. Most of the cases described in these reports are part of a general review of [57] reported 11 cases of hydronephrosis, although their study was mainly focused on the problems related to shunting of the urinary tract in utero.…”

“…US is a non-aggressive way to determine fetal growth and to display fetal anomalies (3), but the findings are difficult to interprete (3). Anyhow, cystic structures can be differentiated from solid ones (8), but their origin and nature remains to be detected by other diagnostic means (3,7,8). The cystic masses found with "real-time" US in the fetus at the 24 th and 34 th week of pregnancy were interpreted as fetal hydronephrosis (2), probably because of low resolution power and scantyness of "gray-scale" sonogram.…”

“…If the diagnosis is in late pregnancy -in advanced fetal life -new problems arise both for obstetrician and for neonatal surgeon, whether in some way "the quality of the life of the child" could be improved (4). The difficulties in interpreting US pictures (3,8) may cause problems concerning the management of prepregnancy. ease report M.

In the fetus of a diabetic woman, at the 24th week of pregnancy urological anomalies (cystic kidney malformations) were found with real-time ultrasound. At the 34th week these findings were confirmed and interpreted to be due to a lower urinary obstruction. Therefore a preterm Caesarean section was performed. In the newborn the left multicystic kidney was removed. The indications for the US screening in pregnancy and difficulties in the interpretation of urological findings of fetal and newborn ultrasonograms are discussed.

“…To the best of our knowledge, the association of UPJO-related hydronephrosis and twinning has not been previously reported. Only two cases of twins with bilateral hydronephrosis have been published one of which was attributed to UPJO [21,22]. Since these three reports were prior to widespread use of USG, a higher percentage of twins with associated UPJO may actually exist.…”

Prenatally detected ureteropelvic junction obstruction: clinical features and associated urologic abnormalities

et al. 2008

Urologic congenital anomalies associated with ureteropelvic obstruction (UPJO) have been previously characterized; however, less data are available regarding these associations in a prenatally diagnosed population. A retrospective study was conducted to evaluate significant clinical features and urological anomalies associated with prenatally diagnosed UPJO. The records of 143 children with prenatally diagnosed hydronephrosis secondary to UPJO were retrospectively reviewed. The gender, side of obstruction, degree of hydronephrosis, associated clinical features, and urological anomalies were noted. Hundred and forty-three children (M/F = 2.7) with a total of 198 affected renal units (RU) presenting with unilateral (61%) or bilateral (39%) UPJO were enrolled. In cases of unilateral obstruction, the left side was affected in 60 children (68%). The grade of hydronephrosis was Grade 1 in 56 RU (28%), Grade 2 in 51 RU (26%), Grade 3 in 50 RU (25%) and Grade 4 in 41 RU (21%). Associated clinical features included prematurity (n = 7, 4.9%), twinning (n = 5, 3.5%) and presentation with renal failure (RF) (n = 2). Excluding contralateral UPJO, other urologic anomalies were encountered in 29 patients (20.3%). Associated vesicoureteral reflux (VUR) was encountered in 11 patients (7.7%, M/F = 2.7). Pyeloplasty was required more often in children with associated VUR (54.5 vs. 18.2%) (P = 0.01). Contralateral multicystic dysplastic kidney (MCDK) was encountered in six patients (M/F = 2), one of whom presented with RF. One child carried the diagnosis of Schinzel-Giedion syndrome (SGS), demonstrating severe developmental and neurological disorders and bilateral hydronephrosis. The more frequent occurrence of UPJO in males with predominantly left-sided location, association with VUR and MCDK, and increased frequency of bilaterality in our prenatally diagnosed patients were similar to historical reports. In addition, prematurity and twinning were independently associated with UPJO. The higher rate of pyeloplasty in patients with associated reflux warrants further investigation.
