BACKGROUND: The management of patients with recurrent urethral strictures represents a challenge for the practicing urologist.
PATIENTS AND METHODS: We used holmium:yttrium-aluminum-garnet (Ho:YAG) laser in the management of recurrent urethral strictures in 13 patients. The energy level was set at 1.0 at a frequency of 10 pulses/sec. No treatment complications were observed. The mean preoperative maximum flow rate by uroflowmetric analysis was 3.8 mL/sec.
RESULTS: Nine patients (69%) continue to do well with no symptoms at a median follow-up of 27 months with a mean maximum flow rate of 19 mL/sec. Of the four patients in whom treatment failed, three were retreated with the Ho:YAG laser. One of them was managed by insertion of a permanent urethral stent, another continues to do well without any further treatment, and the other is managed with dilation by self-catheterization. One of the four failures underwent open reconstructive urethroplasty after recurrence following his first treatment with the Ho:YAG laser.
CONCLUSION: Our preliminary results suggest that Ho:YAG laser ablation of urethral strictures is safe and might be a reasonable alternative endoscopic treatment for recurrent urethral strictures.
