[Efficacy of transurethral 2 microm laser urethrotomy in the treatment of urethral stricture and atresia].

Abstract

OBJECTIVE:

To evaluate the curative efficacy of transurethral 2 microm thulium laser urethrotomy in the treatment of urethral stricture and atresia.

METHODS:

192 patients suffering from urethral stricture (n = 179) or atresia (n = 13), all male, aged 45.4 (38-56), underwent transurethral 2 microm thulium laser urethrotomy. The maximum flow rate (MFR) was measured before operation, immediately after removing the catheter, and 3 and 6 months postoperatively.

RESULTS:

All the patients got fluent urination immediately after the catheter removal with the mean MFR of (16.7 +/- 3.1) ml/s, significantly higher than that before the operation [(3.2 +/- 0.3) ml/s, P < 0.01]. 157 patients got permanent fluent urination without recurrence; 35 patients got recurrence 1 to 3 weeks after the catheter removal and got final cure 3 months later after periodic urethra dilatation. Besides, 6 patients encountered incontinence and all finally got convalescence after physical therapy and exercise. The mean MFR of all the patients 3 months and 6 months postoperatively were (18.7 +/- 3.1) ml/s and (19.2 +/- 2.8) ml/s respectively, both significantly higher than that before operation (both P < 0.01).

CONCLUSION:

Transurethral 2 microm thulium laser urethrotomy is a safe and efficient method in the treatment of urethral stricture and atresia.
