In clinical polycystic diseases mainly include polycystic kidney, polycystic liver, polycystic ovary, etc. The treatment mainly depends on the location of polycystic lesions. Early polycystic kidney is usually found to have cystic changes in the kidneys during physical examination by ultrasound or CT imaging, at this stage, no treatment is usually needed, mainly paying attention to low-salt diet and so on. As the cyst grows and presses on the surrounding tissues or organs, surgery is needed. Depending on the condition, cyst decapitation, nephrectomy, etc. can be chosen. If it develops into end-stage renal disease, dialysis is needed. Polycystic liver usually does not affect liver function and usually does not need treatment. Surgery is required when the cysts increase in size and compress the surrounding organs causing painful symptoms. Depending on the condition of the cysts, liver cyst puncture sclerosis, decapitation and decompression, partial hepatectomy or liver transplantation will be chosen. Polycystic ovary belongs to gynecological system diseases, and is also one of the common clinical causes of menstrual irregularities and infertility. It is recommended that patients visit the gynecology department for systematic treatment. If patients find polycystic disease, it is recommended to go to regular hospitals in time and standardize the treatment under the guidance of doctors.
