Hello @formydad. Sorry that you need more information about your father's experience with a bladder growth. I've been through much of that, but with an important advantage -- my 12 bladder tumors, although malignant, were small and on the surface of the bladder lining and were readily removed in two phases: 1) walk-in surgery using TURBT (transurethral resection of bladder tumors) in an hour-long procedure and 2) six treatments with a solution of "BCG bacteria" to ensure that any cancer seeds were killed. My bladder had been blocked periodically by prostate tissue growth which, when removed, revealed tumors hidden behind it. I had been a moderate smoker for 45 years. Fortunately, the treatments cleared up my problems. In your dad's case, I'm optimistic that his kidney function will return gradually after the removal just this week of the growth in his bladder. My optimism, though, is based on faith not facts, and your doctors are the ones to provide you the information you need and want about the immediate and long-term future. Are you expecting a report soon from the doctors on how the surgery may affect his bladder and how soon kidney function will resume? Martin
