Hello, my husbands PSA has spiked since before his Greenlight Laser for BPH. From 5 to 35 and this is after surgery. He had a catheter in for one year before surgery and so the PSA of 18 at the time was thought to be due to catheter. Did biopsy as initial MRI showed pirad 5 and all 16 were negative. Prostate size over 150 cc. Thoughts, advice or stories we can learne from. They are doing another MRI....
