Hydronephrosis, "distension in varying degrees of pelvis and calyces, accompanied by progressive atrophy of renal parenchyma due to obstruction in urinary flow", is an apparently simple reno-urinary disease, but, in reality, by association of its own characters with those conferred by causative lesions, becomes of a significant complexity. The purpose of this paper is to demonstrate the pluriva...

Study Design Prospective follow-up design. Objective Ureteral injury is a recognized complication following gynecologic surgery and can result in hydronephrosis. Anterior lumbar surgery includes procedures like anterior lumbar interbody fusion (ALIF) and total disk replacement (TDR). Anterior approaches to the spine require mobilization of the great vessels and visceral organs. The vascular sup...

Purpose: Controversies persist on pyeloplasty follow-up, and the aim of this study was to assess the differences and interpretations in results of postoperative ultrasonography and diuretic renograms. Materials and Methods: The study population consisted of 46 patients who underwent pyeloplasty between 1997 and 2003. The average patient age was 7.0 months (range, 2-36 months). Serial changes in...

Granulomatosis with Polyangiitis (GPA, formerly known as Wegener) is a systemic vasculitis characterized by granulomatous involving upper and lower respiratory tract and can also cause necrotizing glomerulonephritis (Umemoto et al. 2012 and Takala et al. 2011). GPA is associated with antineutrophil cytoplasmic autoantibodies (ANCA) against serine proteinase 3 (PR3) (Takala et al. 2011, Dufour e...

BACKGROUND The purpose of the present paper was to evaluate the clinical features of primary vesico-ureteral reflux (VUR) in Thai children. METHODS Children with primary VUR attending in the Nephrology Division, Department of Pediatrics, Prince of Songkla University between 1987-2002 were studied. RESULTS Sixty-five girls and 60 boys with primary VUR were evaluated. Age of diagnosis was sig...

PURPOSE The management of prenatally detected bilateral ureteropelvic junction obstruction (UPJO) remains controversial. We attempted to develop a treatment plan for patients with severe bilateral UPJO. MATERIALS AND METHODS We evaluated the records of 13 patients with prenatally diagnosed grade 3 or more bilateral hydronephrosis that led to the postnatal diagnosis of severe bilateral UPJO. U...

INTRODUCTION At the end of pregnancy, the amniotic fluid (AF) depends basically on renal function, corresponding to fetal urine. Changes in AF, especially oligohydramnios, are reported in association with fetal hydronephrosis (FH). The experimental model using adriamycin in pregnant female rats has a teratogenic effect and has been classically employed to study esophageal atresia. Nevertheless,...

Radiologic imaging of the newborn detected prenatally with hydronephrosis should follow a systematic approach. Upper and lower urinary tract imaging should be performed in most cases in order to determine the etiology and gauge the use of future imaging. An overview of renal ultrasound, voiding cystourethrography, renal scintigraphy, and magnetic resonance urography in the setting of antenatal ...

Fetal intervention for obstructive uropathy was first performed at the University of California, San Francisco in 1981 [1]. Since then diagnostic criteria for fetal intervention have been laid down to assist in proper patient selection [1-3]. Unilateral fetal hydronephrosis doesn’t require prenatal intervention; but prenatal intervention might be required in selected cases, especially when hydr...
