CONTEXT Management of urinary stones is a major issue for most urologists. Treatment modalities are minimally invasive and include extracorporeal shockwave lithotripsy (SWL), ureteroscopy (URS), and percutaneous nephrolithotomy (PNL). Technological advances and changing treatment patterns have had an impact on current treatment recommendations, which have(More)
PURPOSE We prospectively evaluate the safety, morbidity and complication rates for first and repeat transrectal ultrasound guided prostate needle biopsies. MATERIALS AND METHODS In this prospective European Prostate Cancer Detection Study 1,051 men, with total prostate specific antigen between 4 and 10 ng./ml., underwent transrectal ultrasound guided(More)
CONTEXT Medical expulsive therapy (MET) for urolithiasis has gained increasing attention in the last years. It has been suggested that the administration of alpha-adrenoreceptor antagonists (alpha-blockers) or calcium channel blockers augments stone expulsion rates and reduces colic events. OBJECTIVE To evaluate the efficacy and safety of MET with(More)
CONTEXT Low-dose computed tomography (CT) has become the first choice for detection of ureteral calculi. Conservative observational management of renal stones is possible, although the availability of minimally invasive treatment often leads to active treatment. Acute renal colic due to ureteral stone obstruction is an emergency that requires immediate pain(More)
PURPOSE Small renal tumors detected incidentally are considered to have less aggressive potential. This assumption is mainly based on the low tendency to increase in size on serial imaging studies, but histopathological parameters of progression in larger patient series are scant. MATERIALS AND METHODS We reviewed data of 287 tumor bearing kidneys in(More)
PURPOSE We evaluated biochemical parameters and pathological features, as well as biopsy related morbidity of prostate cancer detected on biopsies 2, 3 and 4 in men with total serum prostate specific antigen (PSA) between 4 and 10 ng./ml. These features were compared to those detected on prostate biopsy 1. MATERIALS AND METHODS In this prospective(More)
PURPOSE Two artificial neural networks (ANN) for the early detection of prostate cancer in men with total prostate-specific antigen (PSA) levels from 2.5 to 4 ng/mL and from 4 to 10 ng/mL were prospectively developed. The predictive accuracy of the ANN was compared with that obtained by use of conventional statistical analysis of standard PSA parameters. (More)
OBJECTIVE • To compare oncological outcomes in patients undergoing open radical nephroureterectomy (ONU) with those in patients undergoing laparoscopic radical nephroureterectomy (LNU). PATIENTS AND METHODS • A total of 773 patients underwent radical nephroureterectomy at nine centres worldwide; 703 patients underwent ONU and 70 underwent LNU. •(More)
To investigate the efficacy and safety of dienogest as a long-term treatment in endometriosis, with follow-up after treatment discontinuation. The study included women with endometriosis, who had previously completed a 12-week, placebo-controlled study of dienogest, who participated in an open-label extension study for up to 53 weeks. Thereafter, a patient(More)
