Abstract:
Objective To summarize 20 years' clinical experience of urethroplasty with pedicled tunica vaginalis grafts in the treatment of long-segment anterior urethral stricture (＞2 cm) caused by male genital lichen sclerosus (GLSc). Methods A retrospective study was conducted on the clinical data of 90 patients undergoing urethroplasty with pedicled tunica vaginalis grafts in our hospital. Patients were divided into three groups according to the length of stricture: 4-7 cm (n=25), ＞7-10 cm (n=44), and＞10 cm (n=21). The surgical conditions, changes in preoperative and postoperative maximum urinary flow rate (Qmax), and improvements in the international index of erectile function (IIEF-5) scores were compared among the three groups. Results During the follow-up of 6-48 (average 22.0±2.7) months, 88 patients exhibited unimpeded urination, with a success rate of 97.8%. Retrograde urethrography showed the urethral lumen was well-dilated, the penis was not deformed or strictured, and the sexual intercourse was normal. The Qmax of the three groups was significantly improved 2, 6 and 12 months postoperatively (P＜0.01), but with no statistically significant differences among the three groups (P＞0.05). Similarly, the IIEF-5 scores showed no statistically significant differences among or within the groups (P＞0.05). No serious complications occurred after operation. Urethral stricture occurred in 2 cases after operation, one of which had smooth urination after holmium laser urethrotomy, and the other achieved urination after anterior urethral incision. Conclusion Urethroplasty with pedicled tunica vaginalis grafts is suitable for the treatment of long-segment anterior urethral stricture caused by GLSc. It has the advantages of high surgical success rate, convenient graft harvesting, simple operation, few trauma and few complications. This surgical approach is recommended for primary hospitals.
