Ureteroscopy on Diagnosis and Treatment of Radiolucent Ureteral Calculi(A Report of 40 Cases)

目的探讨输尿管镜术治疗输尿管阴性结石的效果。方法对40例经KUB、B超、IVU或逆行造影检查疑为输尿管阴性结石患者,应用输尿管镜术确诊,并配合气压弹道取石碎石治疗。结果38例顺利进镜,其中15例结石<0.5 cm者,直接镜下钳夹取石,23例结石直径>0.5 cm者经气压弹道碎石,1例尿道狭窄、1例输尿管开口异常者进镜失败改行开放手术及ESWL治疗。结论输尿管镜术在输尿管阴性结石的诊断和治疗中具有重要作用。

Objective To study the effect of ureteroscopy on diagnosis and treatment of radiolucent ureteral calculi. Method 40 eases of doubted radiolucent ureter calculi were treated with ureteroscopy in combination with uteroscopic pnumatic lithotripsy. Result 38 cases were successfully treated, including direct stone extraction in 15 cases with stone less than 0. 5 cm in diameter, pnumatic lithotripsy in 23 cases with stone more than 0. 5 cm in diameter. The rest two eases were failed due to the urethral stricture and mutated ureter opening in each. Conclusion Ureteroscopy plays an important role in the treatment of radiolucent ureteral calculi.
