After alcohol curing treatment for renal cysts, please pay attention to the following postoperative matters: 1. Rest in the observation room for 30-60 minutes, and leave only after there are no uncomfortable symptoms. In case of panic, dizziness, bleeding from the puncture site, abdominal pain, etc., you should inform the doctor in time for timely treatment. 2. Normal activities can be resumed 1 day after surgery, but heavy physical activities are prohibited. 3.A few patients may have transient hematuria or hypothermia after surgery, which are normal reactions after surgery and do not need to be treated. If the body temperature exceeds 38.5℃, you can go to the emergency department for symptomatic treatment and promptly notify the doctor on duty in our department. 4. Come to our department to review the cyst regression in six months after surgery. Within 2 months after alcohol sclerotherapy for renal cysts, the cysts may not shrink and may instead increase in size during the initial 2 weeks, a condition that may be related to inflammatory exudation after treatment. Cysts usually gradually resolve within 3 to 6 months after surgery.
