Majority of kidney cysts are solitary, occur on the surface of one kidney, and in most cases do not produce any symptoms, as it do not cause any problem to the functioning of kidneys. This is also the reason that most of the time, kidney cysts are diagnosed during imaging done for some other cause.
The diagnosis of kidney cyst is mainly done by imaging, i.e. ultrasound and CT scan or MRI scan.
- Imaging for diagnosis of kidney cysts: kidney cysts can be easily diagnosed using imaging techniques, such as ultrasound, CT scan or MRI. Ultrasound is preferred by many, because it is comparatively less expensive to CT scan and MRI. Imaging (especially CT scan and MRI) can help your doctor in determining if your mass in kidney is a tumor or a simple kidney cyst. The correct diagnosis help in determining the treatment modality too, e.g. if it is simple solitary kidney cyst, then no treatment is required if there is no symptoms associated with it.
- Kidney function test help in determining if your kidneys are affected by the cyst or not. Blood test can determine if your kidneys are functioning well or not and if there is any need of treatment.

If there is any symptom or change in size, your doctor may recommend treatment for kidney cyst. Treatment options include,
