ESWL碎石术最常引起的有害作用是肾被膜下或肾周出血。作者报告了使用HM_3 Dornier型震波碎石器碎石的3620病人中有21例出现24个血肿(0.66％)。经过详细检查得知产生的因素与震波的次数、时间的长短无关,亦与结石的性质如大小、数目、部位或成份无关,病人的凝血机制均正常;但发现ESWL前有高血压的患者,特别是未控制好的高血压患者的肾周血肿的发生率显著增高,前者为2.5％,后者为3.8％。故ESWL前未治疗控制好的高血压是发生ESWL后出血的危险因素。
The most common detrimental effect of ESWL lithotripsy is subrenal or perirenal hemorrhage. The authors reported 24 hematomas (0.66%) in 21 of 3620 patients who used the HM_3 Dornier wave lithotripsy gravel. After careful examination, we know that the factors that produce have nothing to do with the number of shock waves and the length of time, nor the nature, such as the size, number, location or composition of the stones. The coagulation mechanism of the patients is normal. However, In particular, the incidence of perirenal hematoma in uncontrolled hypertensive patients was significantly increased, with 2.5% for the former and 3.8% for the latter. Therefore, ESWL untreated control of hypertension is the risk of bleeding after ESWL.
