目的探讨肾周尿囊肿的早期诊断与合理治疗。方法回顾分析６例肾周尿囊肿：５例有外伤史，１例有输尿管结石、肾积水史，术前经Ｂ超、逆行肾盂造影（ＲＰＧ）、ＣＴ检查确诊，２例ＲＰＧ检查发现瘘管。结果手术治疗４例：肾切除１例，囊肿去顶术３例，其中２例加瘘管切除；２例经皮穿刺引流后治愈。术后随访４个月～７年，囊肿无复发。结论肾周尿囊肿经Ｂ超筛选，结合ＲＰＧ、ＣＴ检查可明确诊断。早期发现且无输尿管梗阻者首选囊肿穿刺引流治疗，有瘘管或有输尿管梗阻者宜手术治疗原发病，同时处理囊肿并切除瘘管。
Objective To explore the early diagnosis and reasonable treatment of renal cysts. Methods Six cases of renal cysts were retrospectively analyzed: 5 cases had history of trauma, 1 case had ureteral calculus, history of hydronephrosis. Preoperative examination was confirmed by B-ultrasonography, retrograde pyelography (RPG), and CT. Two cases of fistula were found by RPG examination. . Results The surgical treatment was performed in 4 cases: nephrectomy in 1 case, cyst decapitation in 3 cases, and 2 cases were treated with fistula resection. 2 cases were cured after percutaneous drainage. After 4 months to 7 years of follow-up, there was no recurrence of cysts. Conclusions Renal cysts can be diagnosed by ultrasonography combined with RPG and CT. Early detection of ureteral obstruction without cystopuncture is the preferred method of puncture and drainage. Fistula or ureteral obstruction should be used to treat the primary disease. At the same time, the cyst should be treated and the fistula should be removed.
