PURPOSE: We assessed the feasibility, efficacy and long-term outcome of neodymium (Nd):YAG laser core-through urethrotomy for posttraumatic urethral stricture.
MATERIALS AND METHODS: Between May 1997 and April 2000, 65 patients 5 to 62 years old underwent laser core-through urethrotomy for posttraumatic urethral stricture. Most patients had been involved in a motor vehicle accident but 8 and 3 sustained trauma after tractor injury and a railroad accident, respectively. All patients underwent suprapubic cystostomy formation and 18 had previously undergone anastomotic urethroplasty, railroad or attempted cold knife core-through urethrotomy. Mean stricture length was 2.2 cm. on bi-directional uroradiography and endoscopy. All strictures were in the bulbomembranous urethra except 3, which were prostatic-supraprostatic. The procedure was technically unsuccessful in 4 cases. Core-through urethrotomy was performed using Nd:YAG a 600 mu. contact bare fiber at 15 to 20 W. on an outpatient basis. Catheter removal and voiding cystourethrography were performed at 6 weeks. Uroflowmetry and urethroscopy were done 3 months after urethral catheter removal. Followup was 9 to 44 months.
RESULTS: Nd:YAG laser core-through urethrotomy was performed on an outpatient basis successfully in all except 4 cases without any intraoperative or postoperative complications. Blood transfusion was not required. Although most patients were symptom-free, a few underwent initial optical internal urethrotomy and/or endoscopic dilation before the stricture became stable. The urethral lumen was obliterated again in 2 cases.
CONCLUSIONS: Nd:YAG laser core-through urethrotomy is feasible and effective with good long-term results for posttraumatic urethral stricture.
