肾结石体外震波碎石(ESWL)治疗后石街的处理

MANAGEMENT OF STEIN STRASSE FOLOWING EXTRACORPOREAL SHOCK WAVE LITHOTIPSY(ESWL) FOR RENAL STONES

目的探讨肾结石ＥＳＷＬ术后石街的自然病程、预防及其治疗方法。方法应用ＰＮ－Ⅲ型碎石机治疗肾结石６７５例，其中有８３例发生石街（１２％），石街长度在２－１５ｃｍ之间，大多患者采取复震及其它辅助治疗。结果石街排净最短１２天，最长６８天，排净率１００％，无其它严重并发症发生。结论采用ＥＳＷＬ复震处理石街是一种简单、安全、有效的程序，作者认为石街治疗的难度主要与其密实程度有关。

Objective:This paper is to explore the natural history,measures in the management and prevention of steinstrasse,after renal stones were treated with Extracorporeal Shock Wave Lithotipsy(ESWL).Methods:675 cases of renal stones were treated by ESWL with domestic PN-III lithptripter.Steinstrasse has been observed in 83 patients(12%),between 215cm in length.Most cases were managed by repeated ESWL.Results:The shortest time of stone-freeing of the steinstrasse was 12 days,the longest 68 days.The stone-freeing rate was 100%,with no major complications,Conclusion:That steinstrasse is managed by repeated ESWL is simple,safe and effective procedure.Difficulties in the management are mainly related to the high density of the steinstrasse.
