BACKGROUND The aim of this study was to evaluate the incidence of malignancy in small testicular masses (STMs) treated with testis-sparing surgery (TSS) with intraoperative frozen section analysis and to assess the safety of this surgical procedure. PATIENTS AND METHODS From January 2009 to January 2013, 15 consecutive patients underwent TSS for STMs in a(More)
OBJECTIVE To assess renal dysfunction in chronic kidney diseases using diffusion tensor imaging (DTI). METHODS Forty-seven patients with impaired renal function (study group) and 17 patients without renal diseases (control group) were examined using DTI sequences. Cortical and medullary regions of interest (ROIs) were located to obtain the corresponding(More)
BACKGROUND/AIMS This study was aimed to determine whether host-dependent genetic factors modulate the outcome of HCV infection. METHODS HLA class II DRB and DQB typing was performed in 184 infected patients and 200 healthy volunteers. Among the patients, 149 subjects had persistent HCV viremia (Group 1) and 35 subjects underwent spontaneous viral(More)
Ultrasonography (US) is the method of choice for the diagnosis of bladder disease. It is superior to other imaging techniques, such as urography and cystography, in depicting certain structures and abnormalities. US examination of the bladder should include a study of the ureterovesical junction and the structures round the vesical neck. The examination(More)
The authors report a case of unilateral xanthogranulomatous pyelonephritis, associated with chronic lithiasis studied by standard clinical magnetic resonance imaging protocol and diffusion tensor imaging (DTI). Maps of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) and tractography were reconstructed on both healthy and pathologic(More)
OBJECTIVES To assess the capability of the three-dimensional (3D) Fast Imaging Employing Steady-State Acquisition (FIESTA) sequence in evaluating renal artery stenosis (RAS). METHODS We retrospectively analysed 79 patients referred for suspected RAS, examined by 3D FIESTA and contrast-enhanced magnetic resonance angiography (CE-MRA), using a 1.5T(More)
Primary benign paraurethral tumors in females are observed only rarely. They may occasionally be detected at physical examination or present with symptoms of bladder outlet obstruction. A leiomyoma originating from the smooth muscle fibers of the urethra in a 43-year-old woman is reported. The benign nature of the lesion was suspected on the basis of(More)
Nonspecific granulomatous prostatitis (NSGP) is a relatively uncommon type of chronic inflammation of the prostate, frequently mistaken for carcinoma on digital rectal examination, trans-rectal ultrasound (TRUS) and serum PSA test. It is presently the most frequent variety of granulomatous prostatitis observed at histological examination. The present study(More)
We present the first case of salvage radiotherapy based on the results of 18F-FACBC PET/CT performed for a PSA relapse after radical prostatectomy. The patients underwent 11CCholine PET/CT and multiparametric MRI that were negative while 18F-FACBC PET/CT visualized a suspected local relapse confirmed by transrectal ultrasound-guided biopsy. No distant(More)
Urogenital tuberculosis (UGTB) is the most common form of extrapulmonary TB and is responsible for a destructive inflammation of the renal parenchyma and urinary tract often leading to the loss of kidney function. For these reasons, the early diagnosis of this disease, once considered disappeared in developed countries, is very important to establish a(More)
