最后更新： 2026年4月29日

由于健康检查的宣传得到了宣传，目前人们非常关心他们的健康，因此，大医院的健康促进中心目前将处于发展趋势。大量患者定期接受医疗检查，腹部超声检查是包裹计划中的一种方式。肾脏囊肿是超声检查中偶然发现和检测到的一个问题，促使患者在泌尿外科门诊见我。这个主题我们将主要关注单纯性良性肾囊肿。

肾囊肿总是在体检项目中通过超声检查偶然发现的。

肾囊肿是肾脏最常见的病变。

肾囊肿是肾脏最常见的病变。在正常人群中，它们的最高表达量约为5%。在50岁以上的患者中，超过25%的患病率，以及定期进行体检的40%的发病率，将偶然地报告为肾囊肿。您会注意到，这都是与衰老相关的问题。肾囊肿主要由无功能的肾组织发育而成，随着年龄的增长，肾囊肿会越来越多。

如果我们根据自然史更深入地告诉您有关肾囊肿的信息，那么教科书中描述了几种肾囊肿，从良性到恶性。接近100%的肾囊肿是沉默状态，因此我们经常看到并检测到肾囊肿，尤其是从医学检查成像中。积极的是，此时的超声检查应用将能够为我们提供足够的数据，以阐明哪个是良性的，哪个是恶性的。但这并不意味着所有患者都需要为此做明确的检查-对比扫描CT。

如果超声检查仍存在问题，则CT扫描与造影剂是确定的研究。

When patients meet urologist, a full medical history plus physical examination and the investigations will documented. The details from the imaging on the kidney cysts for example clear or turbid cyst content, size, number and location those are the important information for the prospect follow-up strategy. The important message we must tell patient on the benign kidney cyst is, it will never and ever turn to be a malignancy (Less than 1% the literature has confirmed the malignancy turning point). If patients didn’t experience any cyst-related symptoms for example flank pain or bloody urination, we do nothing beside a regular imaging surveillance.

一旦患者在泌尿科办公室就诊，便会进行完整的病史采集和体格检查。

通常，如果仍然存在肾囊肿，无论哪种方式，它们都会慢慢长大。因此，问题将会出现；我们什么时候需要做些什么？恼人的囊肿相关症状将是关键。如果囊肿的直径大如8 cm，则有几篇关于肾囊肿切除术的文章被提及，它将获得良好的临床效果，复发率更低。

肾囊肿是一个常见的问题，需要患者和医生之间相互了解。需要定期成像以最大化临床结果。要获取更多相关信息，请与您值得信赖的泌尿科医师讨论，或者如果您发短信会很荣幸我。保重并保持安全。

Frequently Asked Questions about Kidney Cysts

What is a kidney cyst?

A kidney cyst is a fluid-filled sac that forms on or within the kidney. Most kidney cysts are simple (benign) cysts and are non-cancerous. They are commonly discovered incidentally during abdominal ultrasound in routine health checkups.

Are kidney cysts dangerous or cancerous?

The vast majority of simple kidney cysts are benign and not cancerous. Less than 1% of simple kidney cysts have any malignant potential. However, complex cysts with internal features such as septations, calcifications, or solid components require further evaluation with a CT scan and specialist consultation.

Do kidney cysts need treatment?

Most simple kidney cysts do not require treatment. If the cyst causes no symptoms such as flank pain or blood in the urine, the standard approach is watchful waiting with periodic imaging surveillance. Treatment is considered only when the cyst becomes large, symptomatic, or shows suspicious features.

How often should I follow up a kidney cyst?

Follow-up frequency depends on the size and characteristics of the cyst. Simple small cysts may be monitored annually or every 1–2 years with ultrasound. Your urologist will advise the appropriate surveillance interval based on your individual case.

When does a kidney cyst need surgery?

Surgery is recommended when a kidney cyst causes persistent symptoms such as flank pain, becomes very large (typically over 8 cm in diameter), causes urinary obstruction, or shows features suspicious for malignancy. Minimally invasive laparoscopic cyst decortication is the preferred surgical technique in such cases.
