Purpose. To study the efficacy of optical internal urethrotomy with intralesional injection of Vatsala-Santosh PGI tri-inject (triamcinolone, mitomycin C, and hyaluronidase) in the treatment of anterior urethral stricture. Material and Methods. A total of 103 patients with symptomatic anterior urethral stricture were evaluated on the basis of clinical history, physical examination, uroflowmetry, and retrograde urethrogram preoperatively. All patients were treated with optical internal urethrotomy followed by injection of tri-inject at the urethrotomy site. Tri-inject was prepared by diluting the combination of triamcinolone 40 mg, mitomycin C 2 mg, and hyaluronidase 3000 in 5-10 mL of saline according to length of stricture. An indwelling 18 Fr silicone catheter was left in place for a period of 7-21 days. All patients were followed up for 6-18 months postoperatively on the basis of history, uroflowmetry, and, if required, retrograde urethrogram and micturating urethrogram every 3 months. Results. The overall recurrence rate after first OIU is 19.4% (20 out of 103 patients), that is, a success rate of 80.6%. Overall recurrence rate after second procedure was 5.8% (6 out of 103 patients), that is, a success rate of 94.2%. Conclusion. Optical internal urethrotomy with intralesional injection of Vatsala-Santosh PGI tri-inject (triamcinolone, mitomycin C, and hyaluronidase) is a safe and effective minimally invasive therapeutic modality for short segment anterior urethral strictures.
目的。研究采用Vatsala-Santosh PGI三联注射剂(曲安奈德、丝裂霉素C和透明质酸酶)病灶内注射行光学尿道内切开术治疗前尿道狭窄的疗效。材料与方法。对103例有症状的前尿道狭窄患者进行术前评估,评估内容包括临床病史、体格检查、尿流率测定和逆行尿道造影。所有患者均接受光学尿道内切开术,随后在尿道切开部位注射三联注射剂。根据狭窄长度,将40mg曲安奈德、2mg丝裂霉素C和3000单位透明质酸酶溶于5 - 10mL生理盐水中配制成三联注射剂。留置一根18Fr硅胶导尿管7 - 21天。术后所有患者根据病史、尿流率测定进行随访6 - 18个月,必要时每3个月进行逆行尿道造影和排尿性尿道造影。结果。首次光学尿道内切开术后的总复发率为19.4%(103例患者中有20例),即成功率为80.6%。第二次手术后的总复发率为5.8%(103例患者中有6例),即成功率为94.2%。结论。采用Vatsala-Santosh PGI三联注射剂(曲安奈德、丝裂霉素C和透明质酸酶)病灶内注射行光学尿道内切开术是治疗短段前尿道狭窄的一种安全有效的微创治疗方式。
