I Have Lost My Bladder Control. I Have Recently Had

I have lost my bladder control. I have recently had a procedure, having two stents inserted where I have had bypass surgery over nineteen years ago. During, and after this procedure I had some short term groin pain, which has completely improved, but leaving me without normal bladder control. I hadn't had any problems prior to this, and when I sleep during the the night my bladder releases the fluids I take in during the day, I do not have the normal urges to relieve myself. I sleep very well through the night. This all took place within the last three weeks.
I had not had any problems with my heart prior to the operation, the heart vessels narrowing were found during a scheduled checkup, all went well and I am feeling excellent. I am back to normal exercises and activity. I have been drinking only water, and passing the fluids produces no pain , I do not smoke or drink, nor am I over weight (165# - 5'9"), and have been a "vegan" for twenty years. I am close to 79 years old,
