[Symptomatic simple cyst of the kidney. Treatment using puncture-aspiration and sclerosis with 95% ethanol]. / Quistes renales simples sintomáticos. Tratamiento mediante punción-aspiración y esclerosis con etanol 95 por 100.

ABSTRACT

Puncture of cystic renal masses is useful in diagnosing a small number of cases when commonly used imaging techniques cannot determine the benign nature of the liquid mass with total accuracy. It can also be used as a therapeutic procedure in those cases with symptomatology arising from the presence of a renal cyst or functional alterations. In the present study, we report our experience using puncture-aspiration and sclerosis with 95% ethanol instillation in 12 renal cysts causing different symptoms. The procedure achieved good overall results with practically no complications. In 10 of the 12 cases the procedure was performed on an outpatient basis.
