How should renal cysts be done by physical examination?

Renal cyst is a tumor? We can not generally say that renal cysts are not tumors, nor can say that renal cysts are tumors. why? This is related to the type and characteristics of renal cysts. Therefore, it is necessary to distinguish between simple renal cysts and recurrent renal cysts, which is related to increased risk of malignancy. The basis is to distinguish renal cysts from 5 stages according to CT examination.

How should renal cysts be done by physical examination?

Class I and II simple renal cysts are common in normal kidneys, benign lesions, generally no symptoms, rarely need treatment, is a regular review, about 6 months to 1 year to check an ultrasound examination, if necessary, do CT examination. But when the cyst increases, the diameter of more than 5cm, which oppression around the organization, causing urinary tract obstruction, then there will be symptoms, you need treatment. Renal cyst medication is no effect, and the main treatment for surgery, including line ultrasound guided renal cyst puncture and injection of sclerotherapy, or laparoscopic renal cyst fenestration. Simple renal cysts in rare cases may be accompanied by rupture, bleeding and infection, then need to be distinguished from renal abscess and renal tumors.

For IIF complex renal cysts, the complexity is between Level II and III renal cysts, the need for close review, try to rule out the possibility of malignant lesions by imaging. Class III complex renal cysts, about 40% -60% are malignant. Options include regular imaging for continuous monitoring, biopsy, or partial nephrectomy in a feasible case. Of course, due to the low accuracy of cystic lesions biopsy, generally not as preferred.

The malignant rate of IV grade complex renal cysts is 85%-100%, all of which need surgical treatment. Partial nephrectomy or radical nephrectomy should be selected according to the condition of the disease.

Therefore, we found a renal cyst at the time of the examination. Neither can we think of the renal cyst as a simple disease and we can not treat the renal cyst as a recurring disease. The correct approach is: through ultrasonic and CT examination results, we can comprehensively evaluate the types of renal cysts and accurately judge the grading, so we can choose close follow-up or biopsy or appropriate surgical treatment.
