Morbidity Following Cystoscopy: Comparison of Flexible and Rigid Techniques

Recent reports on the value of local anaesthetic flexible cystoscopy have emphasised excellent tolerance and preference for the technique over general anaesthetic rigid cystoscopy. However, no study has yet compared the post-operative morbidity rates of these procedures. Tolerance, preference and post-operative symptoms in 100 patients undergoing local anaesthetic flexible cystoscopy were compared with those in 100 patients undergoing general anaesthetic rigid cystoscopy. On initial questioning, 89% of patients found flexible cystoscopy painless and 92% expressed a preference for the same procedure on a future occasion; 98 patients who underwent flexible cystoscopy and 87 who underwent rigid cystoscopy returned a questionnaire on symptoms 1 week after the procedure. The incidence of post-operative symptoms was 33% following flexible cystoscopy and 76% following rigid cystoscopy. Patients in both groups who were undergoing check cystoscopy had a lower incidence of morbidity than those undergoing cystoscopy for other reasons. The results suggest that flexible cystoscopy was well tolerated and preferred by most patients. The morbidity associated with the procedure was also significantly less than that associated with rigid cystoscopy under general anaesthesia.
