Hi doctor, I am a 65 year-old man and my problem is that I had UTI in 1999 after undergoing surgery for hydrocele. Thereafter, I was fine until last September, when i had UTI again and was treated with anitbiotics. Now, after cystoscopy, my urologist has put me on Afdura and I am fine. My urine sample is bacteria free ( pus cells: 2-3) and there's no growth.However, it shows a slight trace of albumin. I am not diabetic. Is this a cause for concern?
