ABSTRACT
Objective To investigate the efficacy of 50% acetic acid as a renal cyst sclerotherapy agent, and with further comparison to that of absolute alcohol. Methods Eighty five patients with renal cyst were undergone sclerotherapy through spiral CT guidance including 43 cases with absolute alcohol and the others with 50% acetic acid as sclerosing agents. All the cysts were aspirated under CT-guidance, beforehand. The sclerosising agents were withdrawn from the cysts after a definite period of retention. Results The disappearance rates of cyst cavity with absolute alcohol and acetic acid were 55.81% and 71.42%, respectively. Complication occurence rates with absolute alcohol and acetic acid were 16.28% and 4.76% , respectively. The average retention periods of absolute alcohol and acetic acid in cyst were (20?4)minutes, and (10?2)minutes, respectively. Statistical analysis demonstrated that all the data in two groups were significantly different. Conclusion Using 50% acetic acid as sclerosising agent in treating renal cyst possesses the better effect and less side effect, providing a tendency to replace the traditional therapy.
