Patient: May 2010 Unit physical examination Intermediate 7*7mm hyperechoic nodule in the right kidney with uneven echogenicity and clear borders May 18, 2010 Shandong Provincial Hospital Imaging Institute Imaging: Hypointense foci of about 5mm in diameter with clear margins were seen in the middle renal parenchyma of the right kidney, CT value -59Hu August 2010 Ultrasound review: 8*7mm hyperechoic nodule was detected. I often feel discomfort on the right side of my lower back, how should I treat it? Is TCM treatment effective? Is it difficult to operate because the tumor is in the middle pole? Can minimally invasive surgery be done? If growth is detected, to 1-2cm, can surgery be done earlier? When is the best time for surgery? Ding Qiang, Department of Urology, Shanghai Huashan Hospital: Malformation is a benign tumor, if the diameter is less than 4cm, it can be followed up regularly without surgery. Drug treatment is usually ineffective. It is recommended to go to orthopedics to check whether there is lumbar muscle or lumbar spine disorder.
