Percutaneous puncture ethanol sclerotherapy is a simple, effective, minimally invasive, and inexpensive procedure to manage symptomatic simple renal cysts. We modified specific technical aspects to balance certain potential intraprocedural factors for ensuring minimal procedural pain and duration as well as maximal clinical therapeutic effects and evaluated the safety and efficacy of this modified technique. A total of 84 eligible patients underwent computed tomography-guided single-session ethanol sclerotherapy using the conventional (group A) or modified (group B) technique. In group B, the puncture route was modified from tansparenchymal to direct for reducing renal injury, and preinjection of low-dose intracystic lidocaine was used to control distending pain caused by ethanol injections; therefore, greater ethanol volumes could be injected for improving the resistance and contact of ethanol with the cyst wall, precluding the need for patient repositioning multiple times to decrease procedural duration. Visual analog scale score for pain and procedural time were significantly higher in group A than in group B. The complication rate was slightly higher in group A than in group B, but the success rate was comparable between the two groups. These results suggest that the modified technique is painless, time-saving, and injury-reducing and can thus improve medical care.
经皮穿刺乙醇硬化疗法是一种简单、有效、微创且经济的方法，可用于治疗有症状的单纯性肾囊肿。我们对特定的技术方面进行了修改，以平衡某些潜在的术中因素，确保最小的手术疼痛和持续时间，以及最大的临床治疗效果，并评估了这项改良技术的安全性和疗效。共有 84 名符合条件的患者接受了计算机断层扫描引导下的单次乙醇硬化疗法，采用常规（A 组）或改良（B 组）技术。在 B 组中，穿刺途径从穿过实质改为直接，以减少肾损伤，并且在注射乙醇前预先注射小剂量的囊内利多卡因，以控制乙醇注射引起的膨胀性疼痛；因此，可以注射更多的乙醇，以提高乙醇与囊壁的阻力和接触，避免因减少手术持续时间而多次重新定位患者。A 组的疼痛视觉模拟评分和手术时间明显高于 B 组。A 组的并发症发生率略高于 B 组，但两组的成功率相当。这些结果表明，改良技术无痛、省时、减少损伤，可以改善医疗服务。
