I am 82 and have have a cyst that was discovered in my epididymis during annual physical by my primary physician over ten years ago. I have had obvious blood in my urine about twice a month for much longer. The cyst has become larger than the testis; I assume that it is a complication of vasectomy at 45 years of age. I also had TURP performed about age 57 for hypertrophy of the prostate. I had surgery for bilateral inguinal hernia when I was 63 and cysts have been found on my kidneys. Biopsy of the prostate four years ago and cystoscopy of the bladder and CAT scan then and once since has been negative for tumors. Repeating these recent procedures seems to be overkill due to risk of injury in procedures and possibility of induction of malignant change during mitosis in healing of tissue. It appears that the vas deferens and prostate empty into the urethra at about the same place. Blood usually appears in the urine at the end of urination but may occur at beginning and throughout particularly if it was present in previous urination. It is more difficult to stop the flow of blood at the end of urination than it is to stop flow of urine. Does this observation give any indication of the source of bleeding? How often should biopsies and CAT scans be done so that risk of procedure is not greater than malignancy? My father lived to 94 and mother to 88. Robert Schaible, Indiana, YYYY@YYYY , 812-876-9884
