hi, 2.5 yrs ago, my father had undergone some operation for enlarged prostate , after that a biopsy was also done which showed normal result. now for past one week he is passing blood with urine. his urine test shows rbc- numerous, pus cells- 3/4, albumin + etc . doctor also asked for ultrasound scan which showed slightly enlarged prostate! ursine culture report is due after 2 days. what do think is the possible cause of thus problem. He is on medication for high BP. cholesterol and hypo thyroid.
