Fifty-two male patients were studied prospectively to assess the results of direct vision urethrotomy in the treatment of urethral strictures. The prognosis was found to be significantly worse in those patients who had received extensive previous treatment. A catheter is recommended for at least 3 days and for 4 weeks in patients who have had minimal previous treatment or who have impaired detrusor function. The use of a urine flowmeter is essential for determining the success of treatment and stricture recurrence. Measurement of the recurrence-free period is important for assessing progressive improvement following repeat urethrotomy and for determining which patients cannot be cured by direct vision urethrotomy.
对52例男性患者进行前瞻性研究，以评估直视下尿道切开术治疗尿道狭窄的效果。结果发现，那些之前接受过广泛治疗的患者预后明显更差。对于之前治疗较少或逼尿肌功能受损的患者，建议留置导尿管至少3天，持续4周。使用尿流计对于确定治疗成功与否及狭窄复发情况至关重要。测量无复发期对于评估重复尿道切开术后的渐进性改善以及确定哪些患者不能通过直视下尿道切开术治愈很重要。
