目的:降低ESWL致肾包膜下、肾周围血肿的发生率。方法:回顾1999～2009年肾结石ESWL后致肾包膜下、肾周围血肿12例的病史资料,分析总结与之密切相关的临床危险因素和术中技术参数。结果:12例肾包膜下、肾周围血肿经积极对症治疗后,9～18个月血肿均消失。高血压、高龄男性、肾下盏结石是重要的临床危险因素,高脉冲能量、多脉冲次数、高脉冲频率是致病的主要技术参数。结论:高血压、高龄男性、肾下盏结石患者术前应良好控制高血压、术中适当降低脉冲能量、合理减少脉冲次数、适当控制脉冲频率是降低ESWL致肾包膜下、肾周围血肿的重要对策。
OBJECTIVE: To reduce the incidence of ESWL-induced renal and renal hematoma in the kidney. Methods: The data of history of renal capsule hematoma and renal capsule hematoma after ESWL of renal calculi from 1999 to 2009 were retrospectively reviewed. The clinical risk factors and intraoperative technical parameters were analyzed and summarized. Results: 12 cases of renal capsule, perihematoma hematoma after symptomatic treatment of positive, 9 to 18 months hematoma were disappeared. Hypertension, elderly men, lower calyx stones is an important clinical risk factors, high pulse energy, multi-pulse frequency, high pulse frequency is the main technical parameters. Conclusions: Hypertension, elderly men and patients with lower calyx stones should be well controlled before operation, and the pulse energy should be reduced properly in order to reduce the number of pulses reasonably. The proper control of pulse frequency is to reduce the subenvelomal and perirenal hematoma of ESWL Important countermeasure
