Hydronephrosis is one of the most common abnormalities detected on routine prenatal ultrasounds, being noted in up to 1% of fetuses. Rarely, severe hydronephrosis coexists with oligohydramnios, which portends a poor prognosis. We review the most recent literature on the results of prenatal intervention in this setting. Presently, the first randomized controlled trial to address whether prenatal...

This study was aimed at evaluating the clinical outcome of infants with antenatally diagnosed hydronephrosis. Our objective was also to determine whether there is a significant correlation between anterior posterior pelvic diameter (APPD) and urinary tract abnormalities detected. We retrospectively analyzed data of 145 infants collected between January 2000 and May 2010. Inclusion criteria were...

Reliable differentiation between obstructive and non-obstructive hydronephrosis is decisive for the further therapeutic management in infants. The results of renal Doppler sonography were compared with diuretic radionuclide renography and with the follow-up results in 33 patients (range: 21 to 98 days). In Doppler sonography, a resistive index (RI) of > 0.9 was considered to be abnormal in the ...

Duplex collecting system of the kidney is a common congenital anomaly urinary tract. It usually asymptomatic clinically with normal renal function. In rare instances, it may complicate giant hydronephrosis. The following case middle aged woman history recurrent tract infections (UTI) and flank pain diagnosed bilateral partial duplex complicated unusual non-functioning lower moiety left hydronep...

AIMS The current study aims to assess the role of ultrasound (US) parameters in explaining the variance of hydronephrosis grades in reno-urinary anomalies, as well as their performance in quantifying the incidence of patients with uropathies. METHODS In this study 196 patients were prospectively included. All of them had renal/urinary tract anomalies and were recruited from 5992 US examined h...

abstract   background: hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. the presence of hydronephrosis is not synonymous with o...

BACKGROUND Infants with neonatal hydronephrosis and a normal voiding cystourethrogram (VCUG) are presumed to have ureteropelvic junction obstruction (UPJO). There is little current information about the natural history of children with hydronephrosis or clinical factors that predict resolution of the radiological abnormality. OBJECTIVE To determine the time course until spontaneous resolution...

INTRODUCTION AND AIM Antenatal treatment of obstructive uropathy, although widely performed, remains controversial. This study evaluated the long-term outcome of managing patients with posterior urethral valves (PUV), highlighting the effect of antenatal vesicoamniotic shunt placement for patients who underwent fetal surgery. METHODS The medical records of 58 patients with PUV were retrospect...

Medical ultrasound is a particularly useful imaging method used in the diagnosis of urinary foetal anomalies. One such anomaly posterior urethral valve (PUV), which congenital malformation male urethra occurring early gestation life. PUV common cause obstructive uropathy males and death during pregnancy. We report from medical perspective on rare high-risk case detected routine antenatal Botswa...

INTRODUCTION Unilateral or bilateral dilation of the ureters occurs commonly during pregnancy. Ultrasonography is a suitable diagnostic method for hydronephrosis; however, it cannot differentiate obstructive from nonobstructive hydronephrosis. Our aim was to evaluate measurable changes in hydronephrosis induced by a mother's positional changes using ultrasonography to differentiate hydronephros...
