Abstract:
Objective To investigate the effect of substitutive reconstruction of long urethral stricture on male erectile function. Methods From January 2007 to January 2009, 23 patients with anterior or posterior long urethral stricture were accepted for a variety of onlay substitutive procedures, including lingual mucosa, perputial skin, and mid-scrotal skin. During the follow-up, data from the International Index of Erectile Function-5 (ⅡEF-5) questionnaire and the Quality of Life (QOL) questionnaire as well as maximal flow rate were recorded. All data were compared with those obtained before surgery. Results Significant improvement in QOL (1.22 ± 1.40, 1.82 ± 1. 17,2.07± 0.46) and maximal flow rate (22.46± 4.65, 23.81 ± 6.22, 21.52 ±7.44 ) could be observed 3, 6 and 12 months after surgery compared with those before surgery (5. 22 ± 0. 75, 3. 93 ± 3. 62)(P＜0.01). No significant differences in the responses to the ⅡEF-5 questionnaire were observed among all patients during the follow-up (P＞0. 05). At the 3, 6 and 12 months after procedure,scores of ⅡEF-5 in patients with anterior urethral stricture ( 17.79 ± 6.42, 16. 57 ± 4. 78, 16.01 ±3.85) were significantly higher than those with posterior urethral stricture (11.67 ± 2.59, 12.35 ±1.83,13. 19±1.67, P＜0.05). In patients with posterior urethral stricture, the multiple linear regression showed that age, time interval of injury and length of stricture were related to the ⅡEF-5score (P＜0.05). Conclusions Substitutive reconstruction for treating the long urethral stricture has little effect on male erectile function. But the location of stricture, especially extended to posterior urethra, may have impact on the erectile function.
