Hello Dr. Yu! I have been sore and swollen in my back since last December, and in the middle of the night, it is even more sore and swollen, and in January this year, CT examination: mild osteophytes in the back, no other abnormalities, and no osteoporosis. A few days ago, ultrasound examination: right kidney cyst 58*54mm with two small crystals, CT examination: right and left liver junction, right liver cyst 10*10mm, calcification of the right posterior lobe of the liver or biliary system stones, a little inflammatory lesion in the lingual segment of the upper lobe of the left lung. After pushing the back, it was intermittently relieved, but still had constant acidity and weakness, and the epigastrium was also stuffy when acid was present, and the appetite was poor. I was not examined in time, but now the right kidney cyst of 58*54mm is so big should be operated immediately? What is the surgery method? Is it directly related to low back pain and swelling? Are other liver, lung and gallbladder causes influential factors? I would like to ask for your diagnosis in your busy schedule, thank you very much! Comments Your cyst is already quite large and needs to be removed as soon as possible with minimally invasive surgery to avoid greater impact on kidney function. Your back pain and swelling may be related to the cyst. It may also be related to lumbar spine osteophytes lumbar muscle strain, which can be lifted with medication. It has little to do with liver and gallbladder. Kidney cyst is a common benign disease in urology, mostly occurs between 30 and 60 years old, more women than men. Most patients are asymptomatic and are often detected by ultrasound on physical examination. When the clinical manifestation is low back pain, soreness or swelling or a lump in the lower back and abdomen, it suggests that the cyst has been very large. Many patients think that kidney cyst is not a big problem and tend to ignore its existence. However, once the cyst grows or symptoms appear, it has already caused irreparable and huge damage to the kidney, and the kidney function is greatly affected. Therefore, kidney cysts are very much in line with the clinical characteristics of “benign disease, malignant manifestation”. Response The treatment of patients with renal cysts is generally related to the size of the cyst. If the cyst is smaller than 4cm, it will have less pressure on the kidney parenchyma and less impact on the kidney function, so we can consider not to operate temporarily and follow up closely with ultrasound. If the cyst is larger than 4cm, the pressure on the kidney parenchyma is greater and the impact on the kidney function is also greater, and there is a risk that the cyst will continue to grow, so surgery should be chosen as soon as possible. The main surgical method is laparoscopic renal cyst decompression, which is a minimally invasive surgery with the advantages of less bleeding, small and beautiful surgical incision, fast postoperative recovery, good therapeutic effect and good patient tolerance, etc. It is highly praised by patients. Tips Minimally invasive laparoscopic surgery is feasible for most patients with renal cysts requiring surgery, and the surgical results are very satisfactory. However, since even cysts of the same size grow in different locations and have different degrees of compression on the kidney, the postoperative recovery of the renal parenchyma, i.e., renal function, also varies, as do the results of postoperative imaging review. The specific situation is analyzed, and preoperative evaluation and adequate communication with patients are still necessary.
