OBJECTIVES Hydronephrosis in patients with bladder cancer is caused by tumour at the ureteral orifice, secondary ureteral tumours, intramural or extravesical tumour infiltration, or compression of the ureter. This study investigated the prognostic impact of hydronephrosis in bladder cancer. METHODS A series of 788 patients were treated with radical cystectomy with curative intent for transiti...

Objective: Congenital hydronephrosis is a common prenatally diagnosed anomaly associated with an incidence of approximately 0.5-1% in newborns. The purpose of this study was to clarify the value of 99 m diethylenetriamine pentaacetic acid (99mTc-DTPA) in the assessment of renal function impairment of pediatric hydronephrosis. Methods: A total of 48 children with unilateral ureteropelvic junctio...

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...

BACKGROUND To assess the effectiveness of the current vesicoureteral reflux (VUR) grading system according to the international classification of VUR (ICVUR) and to evaluate whether VUR grading accuracy could be improved by renal ultrasonography (RU) according to the Society for Fetal Urology (SFU) grading system. OBJECTIVES Therefore, this study assessed the accuracy of the current VCUG stag...

An 8-year-old boy was referred to Pusan National University Yangsan Hospital with left ureteropelvic junction (UPJ) obstruction. He had experienced episodes of intermittent gross hematuria that had first presented at the age of 5 years. He was otherwise healthy and had no previous medical problems. He had no history of urinary tract infections or stones. A physical examination showed no left fl...

OBJECTIVE We evaluated the improvement of hydronephrosis longitudinally after laparoscopic dismembered Anderson-Hynes pyeloplasty in adult patients with ureteropelvic junction obstruction. MATERIAL AND METHODS Sixteen patients underwent laparoscopic pyeloplasty at our institution between January 2006 and June 2012. Hydronephrosis was assessed by ultrasound and intravenous pyelography at 3, 6,...

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...

INTRODUCTION The management of neonates with congenital hydronephrosis (CHN) diagnosed antenatally is still controversial. MATERIALS AND METHODS A prospective study was performed in all newborn infants with CHN born over a 2-year period in order to identify which neonates require a full radiologic investigation including investigation with invasive tests such as voiding cystoureterography (VC...
