Previous study of experimental varicocele models in rats documented HIF-1alpha and VEGF expression combined with angiogenesis in the testis. The results of this study show that varicocele can lead to tissue hypoxia and related pathophysiological events, such as angiogenesis.

Our experience has shown that this new lithotripter is safe and provides a 68% to 86% chance of stone clearance.

Vesicouterine fistula without vaginal leakage of urine, cyclic hematuria and amenorrhea is a rare condition, referred to as Youssef's syndrome. The most common cause of this syndrome is trauma during a cesarean section. Herein a new case is reported.

Introduction: To demonstrate the relationship between testicular microlithiasis and testicular tumor development. Patients and Methods: Between January 1996 and March 2004, bilateral testicular microlithiasis was found in 40 of the 5,263 patients who underwent scrotal ultrasonography yielding a prevalence of 0.76%. Of the 40 patients, 4 patients with concomitant testicular tumors were excluded from the study. The remaining 36 patients were enrolled into the study and followed by ultrasonography at 6-month intervals. Results: Patient ages ranged between 1 and 69 years (mean 31 ± 14 years). The median ultrasonography follow-up was 34 months (range, 1–96). Testicular tumor development was not observed in any of these 36 patients during the follow-up period. Conclusions: Extensive evaluation including computerized tomography, testicular tumor markers and testicular biopsyof patients with testicular microlithiasis is unnecessary and also increases patient anxiety. Yet annual ultrasonography and physical examination should be performed if ever until testicular microlithiasis is completely accepted as a nonpremalignant disease.
