초록

목적: 신장 낭종 경화술에서 어떤 인자가 횟수를 예측할 수 있는 효과적인 인자인지를 고찰하고자 하였다. 대상과 방법: 전산화단층촬영 혹은 초음파를 시행한 37개의 신장 낭종을 후향적으로 검토하였다. 두 명의 영상의학과 의사가 신장 낭종의 크기, 석회화, 중격 그리고 소엽모양의 외형을 평가하였다. 환자는 에탄올을 주입한 횟수에 따라서 '4번 이상' 그리고 '3번 이하'의 군으로 나누었다. 결과: 37개의 신장 낭종 중 6개가 '4번 이상'군에 속하였으며, 31개가 '3번 이하'군에 속하였다. '4번 이상'군은 평균 크기가 409.48 cc였으며, 다른 군은 301.64 cc였다. 7개의 신장 낭종에서 석회화가 있었으며, 이 중 3개의 신장 낭종이 '4번 이상'군에 속하였다. 중격이 있는 신장 낭종은 12개가 있었으며, 이 중 1개만이 '4번 이상'군에 속하였다. 소엽모양을 보이는 신장 낭종은 3개가 있었으며, 이 중 1개만이 '4번 이상'군에 속하였다. 결론: 신장 낭종 경화술의 횟수에 영향을 주는 중요한 인자는 확인되지 않았다. 그러나, 석회화는 신장 난종 경화술의 시술 횟수를 예측할 수 있는 인자가 될 수 있을 것으로 생각된다.

Purpose: To assess the factors facilitating the prediction of the frequency of ethanol injections in successful renal cyst ablation. Materials and Methods: We retrospectively reviewed the computed tomography and ultrasonography scans of 37 renal cysts. Two radiologists evaluated the characteristics of the presenting renal cysts, including size, calcification, septation, and lobulated configuration. Patients were divided into an "above-four" group and "below-three" group, according to the number of ethanol injections. Results: Among the 37 renal cysts, six belonged to the "above-four" group and 31 to the "below-three" group. The mean volume of "above-four" group was 409.48 cc and that of the other group was 301.64 cc. Seven renal cysts included three belonging to the "above-four" group, which showed calcification. Twelve renal cysts presented a multilocular appearance with thin septa, and included a cyst classified under the "above-four" group. Three renal cysts had lobulated configuration, with one of them belonging to the "above-four" group. Conclusion: No significant correlation was found among the different factors in the prediction of the frequency of renal cyst ablation. However, calcification was the most useful parameter for prediction of the number of renal cyst ablations needed.
