Abstract
서론
대부분의 단순 신낭종은 치료가 필요없는 양성질환이나 신낭종에 의한 증상이 있거나 폐
색이 동반되는 경우 적극적인 치료가 필요하다. 일반적으로 덜 침습적인 경피적 신낭종흡인
술이 시행되고 있으며 이것만으로는 재발율이 30-70%로 높기 때문에 경화요법이 함께 시행
되는 추세이다. 그러나 신낭종액을 흡인한 후 경화요법을 시행하고서도 2년 이상 추적관찰
에서 39%의 높은 재발을 보고하고 있어 본원에서는 천자침을 이용하여 낭종액 흡인후 일회
적인 경화요법을 시행한 군과 카테타를 삽입한 뒤에 2회 이상의 반복적인 경화요법을 시행
한 군에서 치료효과를 비교, 분석하였다.

Purpose: Although simple renal cysts are benign and most of them do not require
treatment, intervention is needed when symptom or urinary obstruction appears.
Sclerotherapy of renal cyst is usually performed in conjuction with aspiration in simple
renal cyst because of the high recurrence rate of 30-70% in aspiration alone. We
compared the results of single and repeated percutaneous slcerotherapy in patients with
simple renal cyst.
Materials and Methods: Sixty three patients with symptomatic or urinary obstruction
causing simple renal cysts received ultrasound guided needle aspiration and sclerotherapy
between March 1990 to December 1996. 42 patients received sclerotherapy once
immediately after aspiration(group 1), and 21 patients received sclerotherapy at least
twice after indwelling a 6.0 Fr pigtail catheter into the renal cyst(group Ⅱ). Follow-up
with ultrasonography was performed in a 3 month internal for at least 6 months.
Disappearance of the renal cyst was considered as complete regression and more than
50% reduction in the diameter of the remaining cyst as partial regression.
Results: The mean diameter of the renal cyst in group 1 (6.12cm) and 2(6.75cm) were
not significantly different. Complete and partial regression were 8/42 (19.0%),
16/42(38.1%) for group 1 and 15/21(71.4%), 5/21(23.8%) for group 2, respectively. The
overall success rate was significantly better in group 2(95.2%) compared to group
1(57.1%)(p<0.001). The pre-operative size of the cyst was not related to recurrence
rate(p=0.184).
Conclusions: These data suggest that repeated sclerotherapy using a pigtail catheter is
better than single session for reducing the recurrence of simple renal cyst.
