目的探讨尿道结石梗阻急诊腔内治疗的手术疗效。方法采用气压弹道联合超声及钬激光碎石急诊治疗尿道结石梗阻25例,均为男性,平均年龄20.1岁。后尿道结石11例,前尿道结石14例,结石直径平均1.2 cm。结果 8例患者采用气压弹道联合超声吸附碎石系统碎石,17例采用钬激光碎石,手术平均时间45 min,结石清除率100%。25例均无尿道假道形成及膀胱穿孔等并发症,术中几乎无出血,术后患者排尿通畅,16例随访3～38个月,无尿道狭窄。结论腔内碎石技术治疗尿道结石具有损伤小、成功率高、并发症少、恢复快的优点。处理尿道结石及减少并发症是决定治疗方法的主要因素。
Objective To investigate the surgical treatment of urethral obstruction by emergency endovascular treatment. Methods Twenty-five cases of urinary stone obstruction were treated by pneumatic ballistic combined with ultrasonography and holmium laser lithotripsy, all of whom were male, with an average age of 20.1 years. 11 cases of posterior urethral stones, anterior urethral stones in 14 cases, the average diameter of stones 1.2 cm. Results Eight patients were treated with pneumatic lithotripsy combined with ultrasound and gravel system lithotripsy, and 17 patients were treated with holmium laser lithotripsy. The mean operation time was 45 min and the stone removal rate was 100%. No complications were found in 25 cases, including urethra formation and bladder perforation. There was almost no hemorrhage during operation. Urinary incontinence was postoperatively. 16 cases were followed up for 3 to 38 months without urethral stricture. Conclusion Intrabronchial lithotripsy has the advantages of less injury, high success rate, less complications and quick recovery. Treatment of urethral stones and reduce complications is the main factor in determining the treatment.
