Objectives: We retrospectively reviewed the urethral stricture cases treated in our tertiary center, and assessed the safety and feasibility of the high-pressure balloon dilation (HPBD) technique for anterior urethral stricture. Methods: From January 2009 to December 2012, a total of 31 patients with anterior urethral strictures underwent HPBD at our center, while another 25 cases were treated by direct vision internal urethrotomy (DVIU). Patient demographics, stricture characteristics, surgical techniques, and operative outcomes were assessed and compared between the two groups. The Kaplan-Meier survival analysis was applied to evaluate the stricture-free rate for the two surgical techniques. Results: The operation time was much shorter for the HPBD procedure than for the DVIU ((13.19±2.68) min vs. (18.44±3.29) min, P<0.01). For the HPBD group, the major postoperative complications as urethral bleeding and urinary tract infection (UTI) were less frequently encountered than those in DVIU (urethral bleeding: 2/31 vs. 8/25, P=0.017; UTI: 1/31 vs. 6/25 P=0.037). The Kaplan-Meier survival analysis showed that there was no significant difference in stricture-free rate at 36 months between the two groups (P=0.21, hazard ratio (HR)=0.65, 95% confidence interval (CI): 0.34 to 1.26). However, there was a significantly higher stricture-free survival in the HPBD group at 12 months (P=0.02, HR=0.35, 95% CI: 0.14 to 0.87), which indicated that the stricture recurrence could be delayed by using the HPBD technique. Conclusions: HPBD was effective and safe and it could be considered as an alternative treatment modality for anterior urethral stricture disease.
