PURPOSE The purpose of this study was to analyze the characteristics of initially missed and rebiopsy-detected prostate cancers following 12-core transrectal biopsy. METHODS A total of 45 patients with prostate cancers detected on rebiopsy and 45 patients with prostate cancers initially detected on transrectal ultrasound-guided biopsy were included in the study. For result analysis, the prost...

PURPOSE To investigate the effect of pre-procedural waiting period and anxiety level on pain perception during transrectal ultrasound-guided prostate biopsy. MATERIALS AND METHODS Sixty patients who had undergone transrectal ultrasound-guided prostate biopsy were enrolled in this prospective study. The subjects were asked to fill out the State-Trait Anxiety Inventory Scale-1 to measure the le...

The first application of ultrasound in medical diagnosis occurred in 1942 when Karl Dussik placed transducers on patients’ craniums and recorded the throughtransmission of the sound beam in an attempt to localize a brain tumor.1 In 1949, the first successful pulse echo system, which could record echoes from tissue interfaces, was developed by Douglas Howry and W. Roderic Bliss at the University...

We report a case of prostatic abscess in a 52 year old male with a history of diabetes mellitus. The abscess was treated successfully with surgical drainage by transurethral unroofing of the cavity of the abscess. The use of transrectal ultrasound is valuable in the diagnosis, treatment and follow up of the abscess, while drainage is usually necessary for the treatment, which can be done by tra...

The technique of the standard transrectal ultrasound (TRUS)-guided prostate biopsy was initially demonstrated in the pre-PSA era, the late 1980s when prostate cancer was mostly a high volume, palpable disease.[2] Apart from the addition of extra cores in an extended biopsy technique, the technique remains essentially the same; systematic and nontargeted. It samples only 0.04% of an average size...

OBJECTIVE The aim of this study is to compare the effect of transrectal power Doppler ultrasound (PDUS) and gray scale transrectal ultrasound (TRUS) for the diagnosis of prostate cancer. MATERIALS AND METHODS Seventy-six patients evaluated with transrectal PDUS and TRUS underwent eight systematic TRUS guided core-needle biopsies, with additional cores from abnormal areas. Histologic diagnoses...
