Comparison of Transrectal Ultrasonography-Guided Prostate Biopsies Analgesia's; Rectal Lidocaine Gel Versus Sandwich Anesthesia (Transurethral Plus Transrectal Lidocaine Gel Administration): A Double-Blind, Randomized, Controlled and Prospective Study.

OBJECTIVES

We aimed to evaluate the effectiveness of the additive transurethral anesthetic agent to transrectal anesthetic agent.

METHODS

Transrectal ultrasound-guided 12 core prostate biopsy planned, 237 patients included in our study. The patients randomly divided into two groups. Group 1 (n=113): Only transrectal 2% lidocaine, Group 2 (n=124): Transrectal + Transurethral(Sandwiches) lidocaine gel given to the patients 10 min before the procedure as anesthesia. Immediately after the biopsy, the patient questioned about the level of pain he felt during the needle entry. The evaluation measured by the VAS score. Immediately after biopsy satisfaction rate with the procedure and if rebiopsy was required, acceptance was scored between 1 and 4. The two groups compared statistically.

RESULTS

The mean VAS score of Group 1 and Group 2 was 4.88±1.89 and 3.77±1.83, respectively. The pain level of Group 2 was lower than Group 1' pain level. The difference between the two groups was considered statistically significant (p<0.001). The patient satisfaction rates of Group 1 and Group 2 found to be 2.45±0.71 and 2.78±0.66, and the acceptance rate of rebiopsy was 2.81±0.69 and 3.02±0.51, respectively. The patient satisfaction rate and acceptance rate of the rebiopsy of Group 2 were higher than Group 1. Patient satisfaction level (p<0.001) and rebiopsy acceptance rate (p=0.014) between the two groups found to be statistically significant.

CONCLUSION

In the TRUS-guided prostate biopsies, sandwich anesthesia is a cheap, convenient, tolerable, and effective method.
