[Efficiency and safety of phenazopyridine for treatment of uncomplicated urinary tract infection: results of multi-center, randomized, placebo-controlled, clinical study].

Aim: to evaluate the efficiency and safety of phenazopyridine for the treatment of patients with uncomplicated lower urinary tract infection, accompanied by pain.

Materials And Methods: A multicenter double-blind, randomized, placebo-controlled study with parallel groups to evaluate the efficacy and safety of phenazopyridine in patients with acute uncomplicated cystitis was performed. A total of 60 women were divided into two groups of 30 patients.

[COMPARATIVE EVALUATION OF CURRENT METHODS OF ANESTHESIA IN PERFORMANCE OF TRANSRECTAL PROSTATE BIOPSY].

Prostate biopsy guided by transrectal ultrasonography (TRUS) is largely used in prostate cancer diagnostics. This procedure is usually quite painful and fear of pain could scare patients from this important research. The aim of the study was to compare methods of anesthesia for prostate biopsy.

[The operative cystoscope with joystick control mechanism of flexible tools inserted into the urinary bladder and the ureter].

The authors developed an operative cystoscope with joystick control mechanism of ureter catheters and other flexible tools. This construction allowed control of flexible tools inserted into the bladder and the ureter in various directions, thus providing a necessary observation of the operative field at endoscopic operations on the bladder and ureter. This was one of the factors, which determined the operation success.

[Local anesthesia with articain in operative interventions in urology].

The aim of the work was to improve the technique of local anesthesia with "ultrakain D-S" in surgical operations in urology. The research included 50 patients with penis diseases, 70 patients with diseases of the scrotum body, 40 patients with various prostate diseases complicated by acute urinary retention. Operative interventions in the patients were carried out with "ultrakain D-S".

[The density of prostate specific antigen of the transition zone as an early predictor of prostate cancer].

The investigation included 98 patients with the level of prostate specific antigen (PSA) of blood serum from 0 to 10 ng/ml and with the diagnosis confirmed by the systemic 12-points prostate biopsy. The data obtained clearly show that the PSA density of the transition zone is a potentially true predictor for the early prostate cancer diagnosis in patients with low and middle PSA level (from 0 to 10 ng/ml). When the threshold level of the PSE density in the transition zone is 0.
