Ureteral fibroepithelial polyp causing urinary obstruction.
Ureteral polyps are rare causes of ureteropelvic junction (UPJ) obstruction, particularly in children. We report a nine year-old boy with UPJ obstruction initially suggestive of an obstructive urinary stone. CT showed intraureteral calcification at the UPJ and hydronephrosis. A retrograde pyelogram showed narrowing at the UPJ and partial obstruction that was found to be a ureteral polyp. This c...

متن کاملLabial fusion causing upper urinary tract obstruction.
An infant with dense and nearly complete labial fusion had marked hydroureteronephrosis which resolved after incision of the adherent labia. Although this is an unusual consequence of labial fusion, it argues for upper urinary tract screening in these children.
متن کاملRenin-angiotensin system and unilateral ureteral obstruction
Unilateral ureteral obstruction (UUO) is a clinical scenario that leads to obstructive nephropathy. UUO alters the expression of many mediators in the ipsilateral kidney. Renin-angiotensin system (RAS) is involved in UUO. Angiotensin II (Ang II) and angiotensin 1-7 (Ang 1-7) as the main arms of RAS influence kidney function which may alter by UUO. Ang II via Ang II receptor subtypes I (AT1R) ...
متن کاملRadionuclide demonstration of urinary extravasation with ureteral obstruction.
Two cases of urinary extravasation with ureteral obstruction demonstrated by the radionuclide studies are reported. The value of radionuclide studies in patients with renal transplantation has been reported previously, but studies in patients without transplantation have rarely been described in the literature. Ureteral obstruction may cause urinary extravasation, which may be demonstrated by r...
