We report a case of primary fibroepithelial polyps (FEPs) in the middle of both ureters in a patient with advanced gastric cancer and acute renal failure. Ureteral FEPs are rare benign lesions, and multiple, bilateral lesions are extremely rare. To our knowledge, this report is the seventh case of bilateral FEPs in the literature. Our case has clinical implications because FEPs should be consid...

asymptomatic and there is a delay in diagnosis most of the time. During management of invasive hydatiform mole, ureteral obstruction should be kept in mind. In the case of large, bulky tumors extending into the parametrium, the possibility of ureteral compression should be kept in mind and excluded by appropriate imaging techniques to prevent loss of renal function due to a complication of a cu...

Studies quantifying habitat structure generally use several instruments. This paper aims to propose a new and efficient device to characterize microhabitat structure of small mammals. Seven measurements were taken: plant cover, litter cover, rock cover, canopy cover, and vegetative obstruction at three heights. The device is a 0.25 m2 square wooden frame (0.50 m x 0.50 m) divided in to 100 open...

Ureteral obstruction is associated with reduced expressions of renal sodium transporters, which contributes to impaired urinary concentrating capacity. In this study, we employed a synthetic mitochondrial superoxide dismutase 2 (SOD2) mimic MnTBAP to investigate the role of mitochondrial oxidative stress in modulating the sodium transporters in obstructive kidney disease. Following unilateral u...

The aim of this study was to compare diagnostic efficiency of excretory urography (EU), ultrasonography-guided percutaneous antegrade pyelography (UGPAP), and renal Doppler ultrasonography (DUS) in New Zealand rabbits (n= 20) experimentally induced unilateral partial ureteral obstruction. The resistive index (RI) value was obtained from all rabbits prior to the induction. A partial ureteral obs...

Ureterosciatic herniation, the protrusion of the hernia sac through the sciatic foramen, is an extremely rare cause of ureteral obstruction. We describe a case revealed by severe left back pain in a 72-year-old female. She was referred to our hospital for urological assessment of left hydronephrosis observed by ultrasonography. Intravenous ureterography (IVU) showed findings compatible with a l...
