The peripheral mechanisms of male sexual arousal are well known. Recently, neuroimaging techniques, such as PET or fMRI, allowed the investigation of the subjacent cerebral mechanisms. In ten healthy subjects, we have simultaneously recorded fMRI images of brain activation elicited by viewing erotic scenes, and the time course of penile tumescence by means(More)
PURPOSE We compared [11C]choline-positron emission tomography (PET) with [18F]fluorodeoxyglucose-PET for re-staging prostate cancer in a group of 100 patients. MATERIALS AND METHODS A total of 100 consecutive patients referred for whole body [18F]fluorodeoxyglucose-PET for clinical prostate re-staging after radical treatment for prostate cancer were(More)
BACKGROUND Few predictive models aimed at predicting the presence of lymph node invasion (LNI) in patients with prostate cancer (PCa) treated with extended pelvic lymph node dissection (ePLND) are available to date. OBJECTIVE Update a nomogram predicting the presence of LNI in patients treated with ePLND at the time of radical prostatectomy (RP). (More)
Detection of recurrence in prostate cancer patients with biochemical failure after radical prostatectomy by [11C]choline PET/CT depends on the prostate-specific antigen (PSA) level. The role of other clinical and pathological variables has not been explored. A total of 2,124 prostate cancer patients referred to our Institution for [11C]choline PET/CT from(More)
OBJECTIVE Prospectively evaluate perioperative outcomes and 2-yr follow-up after holmium laser enucleation (HoLEP) and standard open prostatectomy (OP) for treating benign prostatic hyperplasia-related obstructed voiding symptoms, with prostates >70 g. METHODS From March 2003 to December 2004, 80 consecutive patients were randomised for surgical treatment(More)
OBJECTIVE To review and critically analyse all the recent literature on the detection and characterisation of prostate cancer by means of extended and saturation protocols. METHODS A systematic review of the literature was performed by searching MedLine from January 1995 to April 2007. Electronic searches were limited to the English language, and the key(More)
BACKGROUND The management of patients with clinical recurrence of prostate cancer after radical prostatectomy (RP) remains challenging. OBJECTIVE To determine whether the removal of positive lymph nodes at [11C]choline positron emission tomography/computed tomography (PET/CT) scan may have an impact on the prognosis of patients with biochemical recurrence(More)
PURPOSE This study was aimed at assessing prospectively the effect of postoperative intracavernous injections of alprostadil on the recovery of spontaneous erectile function after nerve-sparing radical retropubic prostatectomy. MATERIALS AND METHODS A total of 30 potent patients with clinically localized prostate cancer (clinical stage B1 or B2, Gleason(More)
PURPOSE We compared the impact of HoLEP and TURP on sexual function. MATERIALS AND METHODS Between January 2002 and January 2003, 120 patients with a mean age +/- SD of 65.2 +/- 7.1 years who had benign prostatic hyperplasia were enrolled in this 2-center, prospective, randomized study. A total of 60 patients with a mean age of 65.25 +/- 6.9 years(More)
OBJECTIVES To prospectively evaluate the accuracy of integrated [(11)C]choline-PET/CT in the diagnosis of lymph-node recurrence in prostate cancer patients with biochemical failure after surgery. METHODS Since October 2002, 25 patients with biochemical recurrence (median PSA: 1.98 ng/ml), based on evidence of lymph-node metastases on [(11)C]choline-PET/CT(More)
