單純性腎囊腫發現率甚高,據統計40歲時約有二十百分比,60歲以上約有三十百分比的腎臟可發現單側或雙側的囊腫。一般腎囊腫無特殊症狀,因而不需治療,但有時會有腰痛、發炎、出血、高血壓或影響腎功能的併發症。對於腎囊腫的治療,一般採用超音波導引抽吸或加入凝固劑,開力或採用顯微手術治療。本篇共討論八例單純或多發性腎囊腫接受後腹腔鏡腎囊腫去頂術,平均手術時間為69.5分鐘,留醫滯留3天,病人在平均12.3個月的追蹤時間內,沒有主要的併發症及囊腫再發。因此我們認為有症狀的腎囊腫,後腹腔鏡腎囊腫去頂術是一最佳選擇。
Simple or retention cysts represent the most common cystic abnormality of the kidney. They can be solitary or multiple and involve 1 or both kidneys. Usually, simple cysts are asymptomatic and require no treatment. However, they can occasionally cause lumbar or abdominal pain, in-fection, hemorrhage, hypertension, and impaired renal function.[1,2] Treatment of symptomatic simple renal cysts can be performed by aspiration with or without sclerotic therapy,[3] open sur-gery, or by a minimal invasive procedure,[4] We describe here a laparocopy-aided retroperito-neal approach for the drainage and ablation of symptomatic simple renal cysts. A total of 8 pa-tients with chronic back pain or symptoms related to it, 6 of whom had solitary renal cysts and 2 with multiple cysts, underwent retroperitoneoscopic unroofing of the cysts. The average opera-tion time was 69.5 min and the hospital stay was 3 d. No major complications were noted, and the patients withstood the short hospital stay well. All of the patients were asymptomatic after an average period of 12.3 mo. Retroperitoneoscopic unroofing of renal cysts appears to be a safe and effective surgery for patients suffering from symptomatic simple renal cyst, (J Urol R.O.C.,10:160-163,1999)
