Transurethral resection of the prostate (TURP) is the most popular surgery for men with enlarged prostate, but it also carries the greatest risk of unwanted side effects and complications. It involves cutting out a portion of the prostate using a long tube inserted into the urethra. After the operation, you may experience temporary bleeding or infection, but permanent damage may occur as well. Permanent loss of bladder control occurs in as many as 3% of those who undergo the procedure, while another 5% or more have permanent erectile dysfunction. One in 10 men who have TURP surgery need to get the surgery again within 10 years. Procedures that use other methods of removing portions of the prostate have fewer side effects and less recovery time but also provide the least amount of relief from symptoms of enlarged prostate.
