Clinical Trial Summary

In comparison with transrectal prostate biopsy, transperineal prostate biopsy has the advantage of better sampling from the anterior area, low risk of infection, and no rectal bleeding. The main problems associated with the transperineal method are pain control and additional general or spinal anesthesia. Three types of anesthesia have been reported for transperineal prostate biopsy: (1) spinal anesthesia; (2) general anesthesia; and (3) local anesthesia. From the viewpoint of patient selection (general anesthesia is contraindicated in some patients) and medical cost, local anesthesia is the most suitable choice for prostate biopsy. Periprostatic block is the standard method of local anesthesia for this procedure. However, periprostatic block is insufficient for transperineal prostate biopsy due to high pain sensitivity in this region. A number of new methods to eliminate pain have been reported, including (1) periapical triangle (PAT) block, (2) paraprostatic plus sexual nerve block, and (3) periprostatic block plus pudendal block.However, there is no anatomical basis for some of these methods, and there have been no randomized controlled trials to evaluate their effectiveness, and some methods are technically difficult to learn. In the previous perineal nerve autopsy, we found that there are two branches leading into the prostate and anterior lateral prostatic tissue, which is the main site of puncture pain. There is a fixed position where the two branches appear. Therefore, this anatomical position block may be a useful site for local anesthesia. We named this location the 'transperineal prostate biopsy local anesthesia switch' (abbreviated as TPA switch). In order to validate its effect, we organized this clinical trail.


Description:

Ninety patients scheduled for prostate biopsy will include in this study. The clinical trial validation process will be as follows: (1) all patients are randomly divided into three groups (Figure 1): group 1, subcutaneous local anesthesia+periprostatic block; group 2, subcutaneous local anesthesia+periapical triangle (PAT) block; group 3, subcutaneous local anesthesia+TPA switch (transperineal prostate biopsy local anesthesia switch) block; VAS scores for each puncture and complications will be recorded.

Outcome

Type Measure Description Time frame Safety issue
Primary highest VAS scores the highest VAS (visual analogue scale) scores during the procedure in one patient. A Visual Analogue Scale (VAS) is a measurement instrument that tries to measure a characteristic or attitude that is believed to range across a continuum of values and cannot easily be directly measured. It is often used in epidemiologic and clinical research to measure the intensity or frequency of various symptoms. VAS is the most common pain scale for quantification of endometriosis-related pain and skin graft donor site-related pain. In detail, it is a 10-point categorical scale pain measurement. The score ranges from 0 to 10, and the no pain is 0, and highest pain is 10. ask patients in 2 minutes after prostate biopsy
Secondary Complications Complications associated with local anesthesia. The complication include: bleeding, intoxation of local anesthetic and anaphylaxis of local anesthetic. during the procedures and 1 days after the procedure
Secondary main VAS scores the main VAS (visual analogue scale) scores during the procedure in one patient.

The score ranges from 0 to 10, and the no pain is 0, and highest pain is 10. ask patients in 2 minutes after prostate biopsy
Secondary patients movement During the procedure if there is movement of the body which will affect the process of prostate biopsy. during the transperineal prostate biopsy
