CT引导下经皮穿刺硬化治疗肾盂旁肾囊肿192例分析

CT-guided percutaneous puncture sclerotherapy for parapelvic cysts: clinical analysis of 192 cases

目的总结CT引导下经皮穿刺肾盂旁肾囊肿硬化治疗的技术及经验。方法2002年6月-2012年6月收治192例肾盂旁肾囊肿患者行CT引导下经皮穿刺注射无水乙醇硬化治疗，并随访其疗效及并发症情况。囊肿直径3～8cm，平均4．2cm。结果全部一次穿刺硬化治疗成功，手术时间25—55min，平均38．6min，治疗过程中16例出现肾区疼痛，无须特殊处理自行缓解；8例出现头晕、面部潮红等轻微醉酒样反应。休息30min后缓解。术后6个月随访B超或CT，185例囊肿消失．7例囊肿直径〈2cm，治愈率为96．4％，随访6—24个月，囊肿无复发或增大。结论CT引导下经皮穿刺肾盂旁囊肿硬化治疗，方法简单易行，并发症少，疗效确切，是肾盂旁囊肿治疗的最佳方法之一。

Objective To discuss the technology and experience of CT-guided percutaneous puncture sclerotherapy for the treatment of parapelvic cysts. Methods During the period from June 2002 and June 2012, a total of 192 patients with parapelvic cyst were admitted to authors＇ hospital. The diameter of the cysts varied from 3 to 8 cm with a mean of 4.2 cm. CT-guided percutaneous puncture sclerotherapy was carried out in all patients. All the patients were followed up, and the therapeutic results as well as the complications were analyzed. Results Successful percutaneous puncture sclerotherapy with single procedure was obtained in all patients. The operation time was 25 - 55 minutes with an average time of 38.6 minutes. During the procedure, pain at renal region occurred in 16 patients, which was spontaneously relieved without receiving any special management. Eight patients developed dizzy and flushing, as slight drunk-like reactions, which disappeared after 30 minutes. Six months after the treatment, untrasonography or CT scanning was performed to check the results. The cyst disappeared in 185 cases, and the diameter of the cyst became 〈 2 cm in 7 cases. The effective rate was 96.4%. During the follow-up period lasting for 6 - 24 months, no recurrence or enlargement of the cyst was seen. Conclusion For the treatment of parapelvic cyst, CT-guided percutaneous puncture sclerotherapy is technically-simple with reliable effect and fewer complications. Therefore, this method should be regarded as one of the most optimal therapies.
