目的探讨用钬激光碎石机治疗泌尿系复杂性结石。方法对肾鹿角形结石 ,采用开放手术加钬激光治疗 ;对肾外型肾盂结石和输尿管嵌顿性结石 ,用钬激光切除息肉后 ,根据结石大小采用直接粉碎法或“虫噬”法碎石 ,上尿路结石术后常规留置双J管引流 3～ 4周 ;对前列腺增生合并膀胱结石 ,采用膀胱镜检查后 ,留置外鞘作通道 ,在膀胱无压力下碎石。结果 94例一次碎石成功 ;4例因结石逆散入肾盂和输尿管下段严重狭窄致手术失败。结石粉碎平均时间 2 7min。结论钬激光碎石术是治疗泌尿系复杂性结石的一种高效、安全的方法
Objective To investigate the use of holmium laser lithotripsy in the treatment of complex urinary tract stones. Methods The nephrotic calculi were treated with open surgery and holmium laser. The nephrolithiasis and ureter incarcerated stones were removed with holmium laser and the polyglutamic acid , Conventional urinary tract stones placed double J tube drainage 3 to 4 weeks after surgery; for benign prostatic hyperplasia with bladder stones, the use of cystoscopy, leaving the sheath for the passage of pressure in the bladder without gravel. Results 94 cases of primary gravel success; 4 cases due to stones into the renal pelvis and lower ureter serious stenosis caused surgery failed. The average time of stone crushing 27min. Conclusions Holmium laser lithotripsy is an efficient and safe method for the treatment of complex urolithiasis
