目的对比实时三维超声(RT-3DE)和二维超声(RT-2DE)引导下肾囊肿穿刺硬化治疗[1]的穿刺成功率评价,探讨RT-3DE引导肾囊肿穿刺硬化治疗方面的应用价值。方法回顾性分析2009年7月—2011年7月因肾囊肿抽吸硬化治疗在我科行实时三维及二维超声引导,其中运用三维超声引导60例,二维超声引导89例。结果 60例肾囊肿抽吸硬化治疗运用三维超声引导一次性顺利穿刺引流成功59例,一次性穿刺成功率98.3%(59/60),另1例改变进针途径后穿刺成功;89例肾囊肿抽吸硬化治疗运用二维超声引导一次性顺利穿刺成功引流77例,一次性穿刺成功率86.5%(77/89),8例改变进针途径后穿刺成功,3例重新经皮穿刺成功,1例转外科手术摘除。三维超声引导下肾囊肿穿刺硬化治疗一次性顺利穿刺成功率较二维超声引导下一次性顺利穿刺成功率差异有统计学意义(χ2=6.28,P<0.01)。结论三维超声引导下肾囊肿硬化治疗较二维超声引导下一次性顺利穿刺成功率明显提高,定位更安全、准确、直观及有效,降低术后并发症发生率。
Objective To compare the success rate of puncture of renal cyst under the guidance of real-time three-dimensional ultrasound (RT-3DE) and two-dimensional ultrasonography (RT-2DE), and to explore the value of RT-3DE in guiding the treatment of renal cyst. Methods A retrospective analysis of July 2009 - July 2011 due to renal cyst aspiration sclerotherapy in our department of real-time three-dimensional and two-dimensional ultrasound guidance, including the use of three-dimensional ultrasound guided 60 cases, two-dimensional ultrasound guided 89 cases. Results 60 cases of renal cyst aspiration sclerotherapy using three-dimensional ultrasound guided successful puncture and drainage of a successful 59 cases, the success rate of one-time puncture was 98.3% (59/60), and the other 1 case changed the needle approach after puncture success; 89 cases of renal cysts Aspiration sclerosis treatment using two-dimensional ultrasound guided successful one-time successful drainage of 77 cases, the success rate of 86.5% (77/89), 8 cases of needle approach to change after successful puncture, 3 cases of successful re-percutaneous puncture, 1 Cases transferred to surgical removal. The success rate of successful one-time successful puncture of renal cyst under three-dimensional ultrasound was statistically significant (χ2 = 6.28, P <0.01) than that of two-dimensional ultrasound-guided successful one-time successful puncture. Conclusion The success rate of one-time successful puncture under three-dimensional ultrasound-guided renal cyst sclerotherapy is significantly improved compared with that under two-dimensional ultrasound guidance. The localization is safer, more accurate, more intuitive and effective, and reduces the incidence of postoperative complications.
