The effects of obstruction [urinary tract obstruction (UTO)] and relief on renal development were examined in an experimental model in the fetal lamb. Bladder outlet obstruction was performed at 60 days of gestation; relief was performed by vesicoamniotic shunting at 90 days of gestation. Studies were carried out in obstructed (OF60; n = 11), shunted (SF; n = 5), and control fetuses (CF; n = 11...

Pediatric hydronephrosis is often hideous, and its severity highly correlates with a significantly increased incidence of pathological condition outcome. The management this disease based on the level by identifying clinical manifestation, so performing an early detection crucial to prevent progression. This research aimed determine predictor factors for degree pediatric give better treatments ...

Duplex kidney is one of common major congenital abnormalities of the urinary tract with an incidence about 1% of all live births and higher frequency in females than in males. Majority of duplex kidneys are unilateral. Although the antenatal diagnosis of fetal hydronephrosis is simple, the diagnosis of fetal renal duplication is infrequent, especially in case the collecting system is not dilate...

BACKGROUND Uterine artery pseudoaneurysm (UAP) normally presents genital bleeding in the puerperal period, and severe hydronephrosis rarely presents during pregnancy. We report a rare case of severe ureteral obstruction accompanied by uterine artery pseudoaneurysm in the early second trimester of pregnancy, which was successfully treated by surgical intervention. CASE PRESENTATION A 42-year-o...

This report covers 30 cases of prenatal diagnosis of uni- or bilateral hydronephrosis not associated with an overdistended bladder. Oligohydramnios was observed only in four cases while polyhydramnios occurred in three affected fetuses. In no case was fetal urine aspirated or drained prenatally. Early delivery was performed in four cases with oligohydramnios. Sixteen newborns required surgical ...

Pregnant Wistar rats were injected with hydroxyurea (HU) intraperitoneally (IP) t one of several 6-hour intervals on days 9-10.75 to study the role of circadian growth variations in the teratologic response of the fetuses. Two stocks of rats were studied and the results in each compared. The fetal response to HU, as observed at day 21, was not detectably modified by circadian fetal growth varia...
