Renal calciphylaxis is a benign lesion that does not usually affect a person’s life expectancy; therefore, patients with left renal calciphylaxis can survive for a long time, but the exact duration varies from person to person. The most common type of renal calciphylaxis in the clinic is cystic calciphylaxis. If patients can be detected early, the cyst diameter is below 2.5cm, it usually does not affect kidney function, and patients do not have discomfort symptoms such as back pain, hematuria and high blood pressure, they can be treated with conservative observation and regular follow-up at the hospital. Most patients grow slowly in the short term and usually do not affect life expectancy. If the patient’s cyst is larger, with a diameter of 2.5cm or more, accompanied by renal function impairment, it needs to be removed by surgery in time, which usually does not cause renal failure after surgery and will not affect the life expectancy of the person. It is suggested that patients should pay attention to rest in daily life, avoid overwork and mental tension, pay attention to keep warm and drink more water to avoid urine concentration. If there is any discomfort, it is recommended to visit the nephrology department of a regular hospital for symptomatic treatment after examination by a professional doctor.
