肾盂源性囊肿非血管超声造影诊断的方法及意义

目的 探讨非血管超声造影对剔除肾盂源性囊肿,提高肾囊肿无水乙醇硬化治疗安全性的积极意义.方法 制订纳入标准后对接受超声引导下肾囊肿穿刺无水乙醇硬化治疗的23例患者进行囊肿腔内注射Sono Vue造影剂,以造影剂从囊肿腔内逸出进入同侧肾集合系统内为肾盂源性囊肿的诊断依据,将之剔除出硬化治疗行列.结果 从23例患者中检出3例肾盂源性囊肿,中止硬化治疗;证实4例因形态怪异而疑为肾盂源性囊肿的患者仍为单纯性肾囊肿,继续硬化治疗.结论 囊肿腔超声造影可以有效地鉴别单纯性肾囊肿和肾盂源性囊肿,提高肾囊肿穿刺硬化治疗的安全性.

Non-vascular contrast-enhanced ultrasound in diagnosis of pyelogenic cyst: methods and significance

Objective To investigate the technical feasibility and clinical significance of non-vascular contrast-enhanced ultrasound(NVCEUS) in screening pyelogenie cyst out of simple renal cysts so as to avoid damage to the urinary tract from absolute ethanol while undergoing percutaneous aspiration and ethanol sclerotherapy(PAEST). Methods Following an inclusion criteria 23 patients with renal cysts were selected to receive NVCEUS scanning by means of administrating SonoVue contrast agents through puncture needle into their renal cyst lumen prior to the injection of absolute ethanol for sclerosing treatment. By the demonstration of hyperechoic contrast agents leaving from intra cyst into renal collecting system,a pyelogenic cyst was defined. The patients with this kind of cyst was not allowed for further ethanol sclerotherapy. Results NVCEUS made 3 patients with pyelogenic cyst resembling simple ones free from ethanol selerotherapy,and 4 patients suspicious of pyelogenic cyst due to weird cyst configuration remain in the list of simple cyst for further selerotherapy. Conclusions NVCEUS of renal cyst is highly capable of differentiating pyelogenie cyst from simple cyst and highly valuable in increasing the safety for the procedure of PAEST.
