I guess My mother diagnosed cyst in upper pole of right kidney in ultrasound. She had blood in vomiting (two times) on 6th Nov 18. Thereafter she was fine but complained of pain in right side of abdomen Please go through the report and advise: 1. Is the situation critical to go for surgery urgently 2. What is remedy. If it can be cured with medicines or at least further growth can be stopped. 3. Whether cyst in kidney can be cause of blood in vomiting or further diagnosis required 3. Any other advise you would like to give.
