Preliminary study for Application of Grip instead of Penile clamp in local anesthesia before cystoscopy in men

Abstract

Objective: Penile clamp is medical equipment used to prevent leakage of lidocaine gel from urethra before cystoscopy in men. The purpose of this study is to determine the effectiveness of using Grip instead of penile clamp.

Materials and Methods: During April to July, 2008. One hundred and twenty men who were indicated for cystoscopy and accepted the informed consents in Rajavithi Hospital were enrolled in this study and randomly divided into 2 groups; 60 each. In the first group penile clamp were used while in the second group, Grip were used. For comparing between Grip and penile clamp, what we concerned were compression power, capability to prevent lidocaine gel leakage, loss of urethra sensation, patients satisfaction and compli-cations of both groups. Visual analogue scale (VAS 100mm) were used to compare pain in both groups. Statistical significance determined using the Independent-Samples T-test, Mann-Whitney U-test and Chi-square test.

Results: Sixty patients were included in each group. The demographic characteristics of the patients did not significantly differ between groups. There were no statistically significant between groups in compres-sion power, capability to prevent lidocaine gel leakage, loss of urethra sensation and patients satisfaction. In addition, complication did not appear in both groups.

Conclusions: In instilling local anesthesia before cystoscopy in men, we can use the application of Grip instead of penile clamp at markly reduced cost.
