Hydronephrosis is a common disease characterized by dilation of the renal pelvis and calices, resulting in loss of kidney function in the most severe cases. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) induces nonobstructive hydronephrosis in mouse neonates through upregulation of prostaglandin E2 (PGE2) synthesis pathway consisting of cyclooxygenase-2 (COX-2) and microsomal prostaglandin E synth...

Ureteropelvic junction obstruction is usually intrinsic and is most common in children. Aberrant renal arteries are present in about 30% of individuals. Aberrant renal arteries to the inferior pole cross anteriorly to the ureter and may cause hydronephrosis. To the best of our knowledge, although there are some papers about aberrant renal arteries producing ureteropelvic junction obstruction, t...

PURPOSE Radical nephroureterectomy (RNU) is a standard treatment for upper urinary tract urothelial carcinoma. However, RNU can result in decreased renal function and cannot be treated with adjuvant chemotherapy. We performed a risk group stratification analysis to determine the preoperative factors that are predictive of diminished renal function after RNU. MATERIALS AND METHODS We retrospec...

abstract   background: hydronephrosis is the most common congenital condition that is detected by prenatal ultrasonography. moreover, the widespread use of prenatal ultrasonography results in an increased recognition of fetal hydronephrosis. prenatal hydronephrosis is diagnosed at an incidence of 1:100 to 1:500 by ultrasonographic studies. the presence of hydronephrosis is not synonymous with o...

BACKGROUND Anti-glomerular basement membrane (anti-GBM) antibody-mediated glomerulonephritis (anti-GBM GN) is an autoimmune disease with rapidly progressive glomerulonephritis. Based on a case report of anti-GBM GN following hydronephrosis, we hypothesized that hydronephrosis may act as a trigger for the development of anti-GBM antibodies. PATIENTS AND METHODS We evaluated 11 patients who wer...

UNLABELLED INTRODUCTION Excessive fluid intake can lead to water intoxication, electrolyte abnormalities, exacerbation of heart failure and anatomical changes in the urinary tract that may present diagnostic and therapeutic challenges for patients and physicians. Although the development of nonobstructive hydronephrosis is recognized in patients with central and nephrogenic diabetes insipidu...

The majority of pregnant women in the U.S. undergo prenatal ultrasonography and approximately 0.5% of these examinations will detect fetal malformations. Up to one-half of these abnormalities include the genitourinary system and the most common urological finding is hydronephrosis. Some conditions associated with prenatal hydronephrosis portend a poor prognosis, while others can follow a fairly...
