Surgeons perform transurethral resection of the prostate operations to relieve patients of symptoms caused by an enlarged prostate, or benign prostatic hyperplasias, according to Mayo Clinic. Urinary symptoms include frequent urination, an intermittent flow of urine, urinary tract infections and feeling as if the bladder is never completely empty.
Prostatism, the obstruction of urinary flow and less force of urinary projection, is linked to the presence of benign prostatic hyperplasias, according to John Hopkins Medicine. An enlarged prostate causes compression or blockage of the urethra. A TURP operation trims excess prostate tissue in the urethra that is blocking urine flow, explains Mayo Clinic.
