ABSTRACT
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 patients were divided into 4 groups (40 patients in each group). TRUS-guided periprostatic anesthesia with 1% solution of lidocaine (10 ml) was carried out in the first group. An intrarectal introduction of 5 g EMLA cream (lidocaine 2,5% and prilocaine 2,5%) was applied in the second group. The intrarectal introduction of 10% lidocaine spray (3 doses) was used in the third group. Placebo as ultrasonic gel was utilized for the fourth group. The authors used the 100-score linear visual analog scale (LVS 1-100) and 5-score numeric visual scale (NVS-4). Minimal scores of pain were obtained in patients using TRUS-guided periprostatic anesthesia with 1% solution of lidocaine (10 ml). This type of anesthesia didn't lead to increase of the number of complications.

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.

The proposed evacuator allows prevention of regurgitation of fragments of resected tissue of destructed bladder stones from the lower cavity of the device to the upper one, and then to the urinary bladder and, thus, it reduces loss of the biological material fragment for morphological investigation as well as the bladder stones fragments for an analysis of their chemical composition and structure, more effectively and quicklywash off the urinary bladder during endoscopic operations.

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 control group consisted of patients with similar pathology and operations under local anesthesia, but with lidocain as anesthesia. The data obtained show that in more pronounced anesthetizing effect of "ultrakain D-S" the quantity of the injected drug was less as well as the time necessary for getting anesthesia was shorter than in the control group.
