OBJECTIVES To compare the success and complication rates in the treatment of ureteral stones with a 7.5F versus a 10F ureteroscope. METHODS A total of 100 patients who were scheduled for ureteroscopy to treat ureteral calculi between December 2000 and December 2002 were randomly assigned to procedures with a 7.5F (group 1; n = 50) or 10F (group 2; n = 50)(More)
PURPOSE In this study we investigated hypoxia inducible factor-1alpha (HIF-1alpha) and vascular endothelial growth factor (VEGF) expression, and angiogenesis in an experimental model of varicocele in the rat testis. MATERIALS AND METHODS A total of 30 adult male Sprague-Dawley rats were investigated in 3 groups, namely varicocele group 1 (13), sham(More)
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(More)
OBJECTIVES To assess the possible role of apoptosis in reflux-related renal scarring by investigating how sterile vesicoureteral reflux affects apoptosis of glomerular and tubular cells in the rat kidney. METHODS Twenty-nine rats were assigned to one of three groups: group 1, reflux (n = 10); group 2, sham surgery (n = 9); and group 3, controls (n = 10).(More)
We retrospectively analyzed the results of percutaneous nephrolithotomy operations for treatment of staghorn kidney stone disease in elderly patients and compared surgical parameters and outcomes with a control group of young adult patients. Between 2002 and 2010, 300 consecutive patients underwent percutaneous nephrolithotomy operation for treatment of(More)
PURPOSE We investigated the presence of p53 expression and apoptosis in an experimental model of varicocele in the rat. MATERIALS AND METHODS A total of 30 adult male Sprague-Dawley rats were studied in 3 groups, namely group 1-13 with varicocele, group 2-9 with sham operation and group 3-8 controls. All animals underwent orchiectomy after 30 days and(More)
OBJECTIVE To evaluate the efficacy of uroflowmetry performed through an indwelling catheter on the differential diagnosis of detrusor acontractility. PATIENTS AND METHODS 50 men aged between 51 and 85 years (mean 66 years) presenting to the outpatient urology department with indwelling catheters due to urinary retention were included in the study. In the(More)
PURPOSE To review the treatment efficacy and to assess the complications encountered in patients with single renal or ureteral calculi managed with a new-generation SWL machine, the Siemens Lithostar Modularis Uro-Plus. PATIENTS AND METHODS The stone location, size, minimum and maximum energy used, localization technique, number of shockwaves, fluoroscopy(More)
Both squamous cell carcinoma and carcinosarcoma of the renal pelvis are uncommon. We report on two cases, one carcinosarcoma and one squamous cell carcinoma of the renal pelvis. In the patient with squamous cell carcinoma of the left kidney, the tumor was neither detectable on preoperative radiological evaluation nor grossly visible in the surgical(More)
