OBJECTIVES To determine the diagnostic performance of transrectal ultrasound in virgin patients with polycystic ovary syndrome (PCOS) by receiver operating characteristic (ROC) curve analysis, compared with conventional transvaginal ultrasound assessment. METHODS Ultrasound examinations were performed in 963 Korean women, with transvaginal transducers in 677 women and transrectal transducers ...

Early embryonic mortality can be monitored using various techniques and probably the most accurate one is ultrasonography (USG). Since the widespread implementation of transrectal USG for reproductive research in cattle (Griffin and Ginther, 1992), several studies have reported rates of embryonic mortality during early gestation under field conditions. Vasconcelos et al. (1997) characterized em...

OBJECTIVE To evaluate the correlations between prostate volumes estimated by transabdominal, transrectal, and three-dimensional US and the factors affecting the differences. MATERIALS AND METHODS The prostate volumes of 94 consecutive patients were measured by both transabdominal and transrectal US. Next, the prostate volumes of 58 other patients was measured by both transrectal and three-dim...

PURPOSE The reliability and objectivity of computer assisted transrectal ultrasound are examined. MATERIALS AND METHODS Pathological examination of radical prostatectomy specimens was compared prospectively to automated cancer detection in corresponding transrectal ultrasound images. RESULTS For automated cancer detection, a sensitivity of 0.75 and a specificity of 0.78 were obtained. Moreo...

background : a transrectal ultrasound-guided prostate biopsy is currently the gold standard procedure to detect prostatic adenocarcinoma. there is little information on the clinical utility of this technique for the detection of prostate adenocarcinoma in men with suspected prostate cancer in pakistan. this study seeks to determine the frequency of prostatic adenocarcinoma by using a transrecta...

PURPOSE Surgical management of the high urogenital sinus remains challenging. The anterior sagittal transrectal approach provides optimal exposure, facilitates vaginal dissection and separation from the urethra, and allows reconstruction of the bladder neck musculature. In this study we report our initial experience with this technique. MATERIALS AND METHODS We performed a retrospective revie...

The aim of this study is to evaluate the ability of the random forest algorithm that combines data on transrectal ultrasound findings, age, and serum levels of prostate-specific antigen to predict prostate carcinoma. Clinico-demographic data were analyzed for 941 patients with prostate diseases treated at our hospital, including age, serum prostate-specific antigen levels, transrectal ultrasoun...

PURPOSE We evaluate the feasibility and potential advantages of ProACT system implantation using transrectal ultrasound rather than fluoroscopy for guidance. MATERIALS AND METHODS The transrectal ultrasound guided procedure was done between June and October 2005 in 7 patients with a mean age of 68.4 years (range 53 to 76) with mild to severe stress urinary incontinence after laparoscopic tran...

OBJECTIVE To assess the usefulness of colour power-Doppler transrectal sonography before/after contrast agent in the detection of local recurrence in patients with rising prostate-specific antigen values after radical prostatectomy and to compare with magnetic resonance imaging . MATERIALS AND METHODS 18 patients with rising prostate-specific antigen values after prostatectomy underwent digit...
