I have been diagonosed having simple renal cortical cyst in both the kidynes and the one on the right kidney is clinically observed to be of 7.8 cms length and I am having no urination problem except more than normal frequency of urination and little pain in my back between ribs and the hip. The Urologist has advised that in case of laproscopic surgery there may be a chance of the cyst again growing and only open surgery can get me rid of this. Further as long as it does not pose any serious problem like severe pain and any other complication there is no immediate need for going in for surgery. I would like to get your advice.
Hi, Thanks for writing in. Renal cortical cysts are common and can be seen in most people above age of 60 years. The cyst measuring 7.8 cm on the right side is a big one but as your doctor has said, it is not a concern if there is no clinical symptoms of pain, urinary retention in the kidney or any development of infections. If you are a male and above 60 years of age then your prostate enlargement can cause symptoms of increased frequency of urination, and also, please do PSA levels if you are an elderly male. Talking about surgery, I have seen many people with larger cysts than the one you have and without any symptoms. They have been doing well for years without any concern. I suggest you do not think about surgery and continue to get a follow-up ultrasound every year. Please discuss the increased frequency of urination in regard to any bladder problems with the urologist.
