UNLABELLED Prenatal ultrasonography has revolutionized the detection and management of many urological abnormalities. Vesicoureteric reflux (VUR) which develops in 10% to 15% of cases of prenatal hydronephrosis, is difficult to predict prenatally. While all children with prenatal hydronephrosis should undergo ultrasonography within the first few weeks of life, there seems to be controversy rega...

Antenatal hydronephrosis (ANH) is one of the most common abnormal findings detected on prenatal ultrasound (US), and it has been reported in 1-5% of all pregnancies. The likelihood of significant postnatal pathologic abnormality in the urinary tract correlates with the degree of anterior-posterior diameter (APD) according to the gestational age. Detection of urologic anomalies prenatally permit...

The aim of this paper is to address the dilemmas of the paediatric surgeon when facing an isolated, unilateral, congenital hydronephrosis and discuss the strategic options for the management of this condition. Congenital hydronephrosis, the most commonly diagnosed uropathy in children, is usually a benign and self-resolving condition. Nonobstructive hydronephrosis does not require operative tre...

Uterine myomata at different locations and of differing sizes usually produce different symptoms, including menorrhagia, tenesmus or frequent urination and, occasionally, pelvic pain. Although logically possible, significant obstructive uropathy is rarely associated with the compression of a uterine leiomyoma. We report a case of a large uterine leiomyoma presenting with bilateral hydroureter, ...

Obstructive uropathy is a condition in which the flow of urine is blocked. This causes the urine to back up and injure one or both kidneys. Obstructive uropathy occurs when urine cannot drain through a ureter. Urine backs up into the kidney and causes it to become hydronephrosis. This article introduces recent research reports as references in the renal unilateral partial ureteral obstruction (...

The most common cause of lower urinary tract obstruction in male infants is posterior urethral valves. Although the incidence has remained stable, the neonatal mortality for this disorder has improved due to early diagnosis and intensive neonatal care, thanks in part to the widespread use of prenatal ultrasound evaluations. In fact, the most common reason for the diagnosis of posterior urethral...

The widespread use of prenatal ultrasound results in an increased recognition of fetal hydronephrosis. To determine clinical characteristics and postnatal outcome of fetal hydronephrosis, we performed a retrospective study in children diagnosed as having fetal hydronephrosis between 1990 and 2001. 341 children with 427 dilated kidneys were included. Dilatation of the renal pelvis was caused by ...
