    An unusual case: right proximal ureteral compression by the ovarian vein and distal ureteral compression by the external iliac vein

    A 32-years old woman presented to the emergency room of Bozok University Research Hospital with right renal colic. Multidetector computed tomography (MDCT) showed compression of the proximal ureter by the right ovarian vein and compression of the right distal ureter by the right external iliac vein. To the best of our knowledge, right proximal ureteral compression by the ovarian vein together with distal ureteral compression by the external iliac vein have not been reported in the literature. Ovarian vein and external iliac vein compression should be considered in patients presenting to the emergency room with renal colic or low back pain and a dilated collecting system

    Objective: The aim of this study is to investigate the effect of exogenous glucocorticoid exposure in the prenatal period on hearing, and the effectiveness of an antioxidant, 'aminoguanidine', on the prevention of the inner ear injury. Material and Methods: Twelve pregnant Sprague-Dawley rats were injected with dexamethasone or distilled water beginning from 14(th) day of gestation to delivery. Test subjects were exposed to 110 dB of noise for four hours in a sound isolated environment in order to create a stress effect, when they became two months old. Test subjects were divided into three groups. Group 1: The ones whose mothers were injected with distilled water and who were exposed to 110 dB noise. Group 2: The ones whose mothers were injected with dexamethasone and who were exposed to 110 dB noise. Group 3: The ones whose mothers were injected with dexamethasone and who were exposed to 110 dB noise, and administered 200 mg/kg/day aminoguanidine. Effects of noise and aminoguanidine on hearing and the inner ear were assessed with brainstem evoked response audiometry (BERA) and electron microscopy. Results: Improvement of hearing thresholds of test subjects in group 1 and group 2 two months after noise exposure was statistically significant when compared to the thresholds obtained 48 hours after noise exposure (p0.05) and it was indicated that the application of aminoguanidine was not beneficial. Conclusion: Exposure to the exogenous glucocorticoids in prenatal period does not make the inner ear susceptible to the effect of noise. Aminoguanidine was not found effective to prevent possible injury.WoSScopu
