Extrarenal pelvis is an anatomical variant that appears as a large hypoechoic mass just outside the renal sinus and can be confused with hydronephrosis, especially on a point-of-care renal ultrasound. Unlike hydronephrosis, it is not associated with dilated calyces, parenchymal thinning, hydroureter, or enlarged kidney per se.

Giant hydronephrosis is rare to be seen in adults. Herein, we report a case of a 20-year-old male referred for abdominal pain. A radiological study revealed a giant left hydronephrosis. Nephrectomy was performed. During the operation, the ureteropelvic junction obstruction position was revealed.

BACKGROUND Ectopic ureters (EUs) associated with varying combinations of urinary incontinence, hydronephrosis, and urinary tract infection have been identified in related North American Entlebucher Mountain Dogs. OBJECTIVES To characterize the disease phenotype in affected dogs and evaluate possible modes of inheritance. ANIMALS Twenty client-owned Entlebucher Mountain Dogs. Nine dogs had c...

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...
