Background. Epidemiological studies have reported various results relating preoperative hydronephrosis to upper tract urothelial carcinoma (UTUC). However, the clinical significance and prognostic value of preoperative hydronephrosis in UTUC remains controversial. The aim of this study was to provide a comprehensive meta-analysis of the extent of the possible association between preoperative hy...

PURPOSE To measure shear wave velocities (SWVs) by acoustic radiation force impulse (ARFI) ultrasound elastography in normal kidneys and in hydronephrotic kidneys in young children and to compare SWVs between the hydronephrosis grades. METHODS This study was approved by an institutional review board, and informed consent was obtained from the parents of all the children included. Children und...

PURPOSE This study aimed to determine the predictors of ipsilateral hydronephrosis after ureteroscopic lithotripsy for ureteral calculi. MATERIALS AND METHODS From January 2010 to December 2014, a total of 204 patients with ureteral calculi who underwent ureteroscopic lithotripsy were reviewed. Patients with lack of clinical data, presence of ureteral rupture, and who underwent simultaneous p...

BACKGROUND AND OBJECT The cases with adult hydronephrosis are usually performed either conservative surgery or nephrectomy according to the grade of residual renal function. The residual renal function of adult hydronephrosis are usually suspected with analysis of concentration and/or clearance of the renal urine content after percutaneous nephrostomy. However, percutaneous nephrostomy is invas...

Antenatal hydronephrosis and vesicoureteral reflux (VUR) are common renal tract birth defects. We recently showed that disruption of the Robo2 gene is associated with VUR in humans and antenatal hydronephrosis in knockout mice. However, the natural history, causal relationship and developmental origins of these clinical conditions remain largely unclear. Although the hydronephrosis phenotype in...

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...

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,...
