The Role of Guide Wire in Internal Urethratomy Under Direct Vision

Background & aim: Urethral Stricture (US) is a common urolologic problem. Direct optic internal urethratomy (DOIU) is a common option for treating US. The purpose of this study was to investigate the role of the guide wire to facilitate direct vision internal in adult male patients. Methods: In this prospective study, 84 patients with anterior urethral stricture randomly divided into two groups. The first group underwent routine DOIU surgery and the second group internal urethratomy was carried out using Wolf ureteroscope 8-9.8 French and guide wire 0.035 French which inserted into bladder. Data were collected and analyzed using software (spss). Results: The mean operation time was 14 minutes in group one and for group 2 was 10 minutes. The comparison of complications after surgery showed that in the first group urethral bleeding accrued in 4 patients (9.52%) and fever infection was seen in 3 patients (7.14%) respectively but no such events were observed in group 2. The only late complication in both groups was recurrence of the stricture that was seen in 8 patients (19.04%) of group one and 3 patients (7.14%) of group 2. Conclusions: The results of this study showed that using a guide wire during DOIU may facilitates the procedure shortens the operation time and reduce the effects of short and long-term operation
