Steinstrasse (SS) is a known complication of shock wave lithotripsy (SWL). Although the majority of SS clears spontaneously, about 6% require intervention. This study was carried out to identify the factors that determine the need for intervention in SS.
This was a retrospective study of all patients who developed steinstrasse following SWL at our center. They were divided into two groups: a) Those cleared spontaneously and b) Those required intervention. The two groups were compared with regard to demographic profile, stone factors and factors related to steinstrasse.
Out of 2436 cases of SWL, 89 (3%) formed steinstrasse. The majority of the patients (35%) who required intervention had stone sizes of 10-14 mm. Coptcoat type III steinstrasse required significantly more interventions for clearance ( = 0.001). The site and the size of the SS was not a predictor of intervention for SS.
Early intervention is warranted in patients with steinstrasse where the lead fragment is >5 mm (Coptcoat type III).
石街是冲击波碎石术（SWL）的一种已知并发症。尽管大多数石街会自行清除，但约6%的患者需要干预。本研究旨在确定决定石街干预需求的因素。
这是一项对在我们中心接受SWL后出现石街的所有患者进行的回顾性研究。他们被分为两组：a）自行清除的患者和b）需要干预的患者。比较两组患者的人口统计学特征、结石因素和与石街相关的因素。
在2436例SWL病例中，89例（3%）形成了石街。大多数需要干预的患者（35%）结石大小为10 - 14毫米。Ⅲ型Copctcoat石街清除所需的干预显著更多（ = 0.001）。石街的部位和大小不是石街干预的预测因素。
对于石街中先导碎片>5毫米（Ⅲ型Copctcoat）的患者，有必要进行早期干预。
