A 5-year-old boy presented with progressively increasing abdominal distension since birth with no associated urinary or gastrointestinal symptoms. A large, non-tender, soft, cystic intra-abdominal lump occupying almost the whole abdomen could be palpated (fi gure 1). Other systemic examination and all blood tests were normal. A contrast-enhanced CT scan revealed a large complex cystic mass of s...

We read with interest the article written by Dr. Lee et al. [1] on renal involvement in Erdheim-Chester disease (ECD). We agree with the authors on the long asymptomatic period of obstructive nephropathy that occurs in ECD. In our experience, a 60-year-old female, suffering from diabetes mellitus, who was treated with metformin, was admitted for fever, abdominal pain, diarrhoea, and acute renal...

hydronephrosis occurs as a congenital or an acquired condition following obstruction of the urinary tract. in this study, a four month old male holstein calf with emaciation, growth retardation and a poor dry scruffy hair coat was examined because of remarkable distention of right abdomen. at necropsy, right kidney was hydronephrotic as a very big fluid-filled round pelvis with the presence of ...

INTRODUCTION Supporting an "ultrasound-first" approach to evaluating renal colic in the emergency department (ED) remains important for improving patient care and decreasing healthcare costs. Our primary objective was to compare emergency physician (EP) ultrasound to computed tomography (CT) detection of hydronephrosis severity in patients with suspected renal colic. We calculated test characte...

Experimental hydronephrosis induced by partial ureteral obstruction at 3 wk of age causes hypertension and renal impairment in adult rats and mice. Signaling by Ephrin receptors (Eph) and their ligands (ephrins) importantly regulates embryonic development. Genetically modified mice, where the cytoplasmic domain of the EphA4 receptor has been substituted by enhanced green fluorescent protein (Ep...

This study was performed to evaluate the role of postnatal ultrasonography (US) in predicting the final diagnosis and need of surgery of antenatal hydronephrosis patients. One hundred and twenty six renal units (RUs) of 76 patients with diagnosis of antenatal hydronephrosis (ANH) were studied. An early postnatal US no later than the first week of life was requested. Voiding cystourethrography (...

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...

Recently, Yang et al. (1) published the abdominal computed tomography (CT) images showing diffuse gas within the bladder wall and a prominent air-fluid level as the typical manifestation of emphysematous cystitis. However, it’s not only involved in the bladder wall but also in the bladder lumen (2, 3). We hereby present a case of gaseous bladder temponade causing obstructive uropathy a rarely s...

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...
