RESUMEN
OBJECTIVE: Our goal was to evaluate the effect of previous history of direct vision internal urethrotomy (DVIU) on success rate of open urethroplasty in patients with bulbar urethral stricture. PATIENTS AND METHODS: We analyzed 133 patients who underwent open urethroplasty for bulbar urethral stricture between January 2008 and May 2017. Patients with penile and fossa navicularis stricture were excluded. We evaluated the effect of previous history of DVIU on success rate of open urethroplasty in patients with urethral stricture. Success of open urethroplasty was defined as disappear of voiding symptoms with maximum flow rate above 15 ml/s. The patients were followed for complications and outcome. RESULTS: Mean age was 54.05 ± 16.5 years. Mean length of stricture was 23.74 ± 10.23 mm. Mean follow-up was 39.77 ± 28.0 months. A total of 76 patients (57.1%) had no history of DVIU. On the contrary, 15.8% had history of DVIU once, 12% had twice, and 15.2% had more than twice. Success rate of open urethroplasty in patients who had no history of DVIU was 84%. However, this success rate was 71.4% in patients who had history of DVIU (P = 0.001). CONCLUSION: DVIU is easy, simple, and noninvasive technique in treatment of urethral stricture, so it is frequently used among urologists. However, it could not be an alternative technique to open urethroplasty. Internal urethrotomy can be used in some certain indications. Success rate of open urethroplasty can be affected by previous history of any endoscopic procedures.
