ABSTRACT
Abstract

Objective:

To investigate the efficacy of 24-h interval multiple-session ethanol sclerotherapy for the treatment of simple renal cysts. Materials and

Methods:

The study sample included 58 patients (mean age, 65.37 ± 11.95 years). We included 76 simple renal cysts that were treated with percutaneous aspiration with a minimum of two sessions of 95% ethanol sclerotherapy in a 24-h interval between sessions. Patients were evaluated at 1, 3, and 6 months after the intervention for the efficacy of the treatment. Treatment success was defined as a complete regression of a cyst or a > 50% reduction in its volume, with no recurrence of symptoms.

Results:

The mean preprocedural cyst size was 72.98 ± 25.14 mm, and the mean preprocedural cyst volume was 205.76 ± 244.15 mL. The mean volume of ethanol used in the first sclerotherapy session was 62.76 ± 30.71 mL. The mean fluid accumulation in the cysts at the end of the first 24-h interval was 4.66 ± 7.13 mL. The mean quantity of ethanol used in the second sclerotherapy session was 26.48 ± 22.2 mL. A third sclerotherapy session was required in only 10 (13.2%) of the cysts. The mean follow-up period was 52.84 ± 37.83 months. The rate of complete regression was 97.4% for the whole sample at the end of the follow-up.

Conclusion:

Ethanol ablation with 24-h intervals is a safe and effective treatment option in the minimally invasive percutaneous treatment of simple renal cysts.
RESUMO
Resumo

Objetivo:

Demonstrar a eficácia da escleroterapia com etanol em sessões múltiplas em intervalos de 24 horas no tratamento de cistos renais simples.

Materiais e Métodos:

Foram avaliados 76 cistos renais simples de 58 pacientes (média de idade 65,37 ± 11,95 anos) submetidos a aspiração percutânea e ao menos duas sessões de escleroterapia com etanol 95% num intervalo de 24 horas. Considerou- se sucesso de tratamento a regressão completa ou uma redução > 50% do volume do cisto, sem recorrência dos sintomas. Os pacientes foram reavaliados 1, 3 e 6 meses após o procedimento.

Resultados:

Antes do procedimento, a média do tamanho dos cistos foi de 72,98 ± 25,14 mm e a média do volume dos cistos foi de 205,76 ± 244,15 mL. A quantidade média de etanol utilizada na primeira sessão de escleroterapia foi de 62,76 ± 30,71 mL. A média de acúmulo de líquido ao final do intervalo de 24 horas foi de 4,66 ± 7,13 mL, sendo utilizada uma média de quantidade de etanol de 26,48 ± 22,2 mL na segunda sessão de escleroterapia. Uma terceira sessão de escleroterapia foi necessária em apenas 10 (13,2%) dos cistos. Na amostra geral, a taxa de regressão completa foi de 97,4%. O tempo médio de seguimento foi de 52,84 ± 37,83 meses.

Conclusão:

A ablação com etanol em intervalo de 24 horas é uma opção de tratamento segura, eficaz e minimamente invasiva no tratamento percutâneo de cistos renais simples.
