Retroperitoneal paraganglioma presenting as right-sided varicocele: case report.

Unlabelled: Varicocele, the most important identifiable pathological cause of male infertility, is rarely observed on the right side. In isolated cases of right-sided varicocele, the presence of retroperitoneal masses compressing the inferior vena cava should be considered by further investigation. The retroperitoneal masses that are detected tend to grow rapidly due to their location and may be very large at the time of diagnosis.

Efficacy of silodosin in the treatment of distal ureteral stones 4 to 10 mm in diameter.

Purpose: Few studies have investigated the efficacy of silodosin, a recently introduced selective alpha 1-A adrenoceptor antagonist, in medical expulsive therapy (MET) for ureteral calculi. The results of these studies, which all evaluated the efficacy of 8 mg/day, indicate that silodosin is a potential treatment for ureteral calculi. This study investigated the efficacy of 4 mg/day of silodosin for MET of distal ureteral stones 4 to 10 mm in diameter.
