[Simple renal cysts in children: treatment with ethyl alcohol injection into their lumen].

OBJECTIVE

The authors assess the efficacy of treatment of simple renal cysts with 95.5% ethyl alcohol injected into their lumen.

MATERIAL AND METHOD: The diagnosis was confirmed by traditional US and color Doppler, urography, and renal scintigraphy. In four children with simple renal cysts ultrasound-guided puncture, aspiration of fluid and instillation of 95.5% of ethyl alcohol for 15-20 minutes were performed and a needle was withdrawn.

RESULTS

In three children 3 weeks after the procedure diameter of cysts began to diminish and by the 5th week cysts were not detected in US. In the fourth child the cyst started to diminish 2 months after the procedure and disappeared after the next 3 months. There was no cyst recurrence after the procedure (average follow-up: 22 months).

CONCLUSIONS

In 4 children treatment of simple renal cyst with 95.5% ethyl alcohol has proved safe and effective treatment.
