Contribution of transcutaneous ultrasonography to the evaluation of urethral strictures.

The aim of our study was to investigate the accuracy and sensitivity of ultrasound in detecting urethral strictures. Between 1992 and 1994, 117 patients with stricture of the anterior urethra were evaluated by retrograde urethrography, ultrasonography and urethroscopy.

The value of prostatic specific antigen in the early diagnosis of prostatic cancer: a Greek view.

Objective: To assess whether it is worthwhile to screen asymptomatic men for prostate cancer using serum prostate specific antigen (PSA) and to determine how many patients could be cured of prostatic carcinoma if detected by screening.

Patients And Methods: Between June 1992 and January 1994 the serum PSA level of 1400 asymptomatic men over 50-years-old was assessed. Those men with PSA levels < 4 ng/mL were not evaluated further.

Influence of digital examination, cystoscopy, transrectal ultrasonography and needle biopsy on the concentration of prostate-specific antigen.

The influence of various prostatic manipulations, including digital rectal examination, cystoscopy, transrectal ultrasonography and transrectal needle biopsy, on the serum prostatic-specific antigen (PSA) levels in 170 men, were examined. We found that digital rectal examination, cystoscopy and transrectal ultrasonography had no significant effect on PSA levels, except for transrectal needle biopsy, which caused an immediate increase of serum PSA in 96.2% of the patients lasting more than 2 weeks in 42.
