background and purpose: posterior urethral valve (puv) is one of the most severe urinary tract anomalies presenting as antenatal hydronephrosis that could lead to severe dilatation and functional impairment of one or both kidneys. the aim of this study was to analyze our experience on patients with a diagnosis of puv. materials and methods: in this prospective study neonates with a diagnosis of...

UNLABELLED We investigated the value of supranormal function and renogram patterns on (99m)Tc-mercaptoacetyltriglycine ((99m)Tc-MAG3) scintigraphy in relation to the extent of hydronephrosis for predicting ureteropelvic junction (UPJ) obstruction in the newborn. METHODS We studied 48 patients with prenatally diagnosed unilateral hydronephrosis that was confirmed on postnatal ultrasonography. ...

In a previous paper (Keith and Pulford) we described a method for producing experimental hydronephrosis, which permitted the study of renal function in this condition for periods varying from weeks to months. The method used was the partial obstruction of both ureters near the ureteropelvic juncture. After a thorough functional study of hydronephrosis thus produced, further experiments were car...

To assess the influence of the ureter on renal washout during 99mTc-DTPA diuresis renography, ureteral images were reviewed in 42 children (median age: 5 mo) referred for hydronephrosis. Sixty-minute acquisitions were obtained in hydrated patients under bladder drainage. Furosemide was injected at 30 min. An abnormal ureter was defined as an intense and continuous image of greater than 10 min. ...

The incidence of endometriosis cases involving the urinary system has recently increased, and the bladder is a specific zone where endometriosis is most commonly seen in the urinary system. In the case presented here, a patient presented to the emergency department with the complaint of side pain and was examined and diagnosed with severe hydronephrosis and bladder endometriosis was determined ...

Corticosteroids were successfully used to treat a 66-year-old man with retroperitoneal fibrosis (RPF) and previously diagnosed membranous nephropathy. Proteinuria was noted at the age of 51 years, and membranous nephropathy was diagnosed by renal biopsy. Ten years later, he presented with right hydronephrosis and renal dysfunction, and was diagnosed as having RPF based on the typical diagnostic...
