Description

(Purpose) The analgetic efficacy of intraurethral instillation of anesthetic jelly in rigid cystoscopic examination for men is not clearly confirmed. This study evaluated the usefulness of intraurethral instillation of anesthetic jelly by questionnaires regarding the pain and uncomfortable feelings during and after the cystoscopic examination.<br>(Materials and methods) A total of 62 men were enrolled in the study. Sixteen patients had not received cystoscopy previously (first cases), and 46 had prior experiences of cystoscopy more than twice (repeat cases). These patients were sequentially divided into two groups; one group (jellygroup) received intraurethral instillation of oxybuprocaine hydrochroride jelly (Benoxil® jelly) prior to cystoscopic examination, and the other group (no-jelly-group) did not receive the jelly instillation. Pain during the jelly instillation to examination, and uncomfortable feelings at micturition after the examination was evaluated by questionnaires.<br>(Results) Instillation of the jelly itself caused considerable pain, which almost similar to that of scope insertion. There was no significant difference in pain score between jelly-group and no-jelly-group during the insertion of the scope to examination. The miction pain after examination was significantly severer in the jelly-group than in the no-jelly-group in repeat cases. In addition, 75% of repeat cases felt better comfortableness when jelly was not instilled, and 96% of repeat cases did not want jelly instillation for their future examination.<br>(Conclusions) Intraurethral instillation of anesthetic jelly had no efficacy for reducing the pain during cystoscopy. Instillation of the jelly itself caused considerable pain, and it made pain and uncomfortable feelings after the examination worse. These results suggested that the instillation of anesthetic jelly before rigid cystoscopy in men might not be useful enough for reducing the uncomfortable feeling during the examination.
