The prostate is a gland that is part of the male reproductive system. It consists of three lobes, and surrounds the neck of the bladder and urethra (tube that channels urine from the bladder to the outside through the tip of the penis). The prostate...
weighs approximately one ounce (28 g), and is walnut-shaped. It is partly muscular and partly glandular, with ducts opening into the urethra. It secretes an antigen called prostate-specific antigen (PSA), and a slightly alkaline fluid that forms part of the seminal fluid (semen) that carries sperm.
A common prostate disorder is called benign prostatic hyperplasia (BPH) or benign prostatic enlargement (BPE). BPH is due to hormonal changes in the prostate, and is characterized by the enlargement or overgrowth of the gland as a result of an increase in the number of its constituent cells. BPH can raise PSA levels two to three times higher than normal. Men with increased PSA levels have a higher chance of developing prostate cancer. BPH usually affects the innermost part of the prostate first, and enlargement frequently results in a gradual squeezing of the urethra at the point where it runs through the prostate. The squeezing sometimes causes urinary problems, such as difficulty urinating. BPH may progress to the point of generating a dense capsule that blocks the flow of urine from the bladder, resulting in the inability to completely empty the bladder. Eventually, this could lead to bladder and kidney malfunction.
Transurethral resection of the prostate (TURP) is the treatment of choice for BPH, and the most common surgery performed for the condition. "Transurethral" refers to the procedure being performed through the urethra. "Resection " refers to surgical removal.

A Transurethral Resection of the Prostate or TURP is a procedure to expand the dimensions of the urethra or urine outflow tract. This video shows what a urologist sees during a TURP. Note that this video shows surgery on an living human.
An enlarged prostate can cause urinary problems due to its location around the male urethra (A). In TURP, the physician uses a cystoscope to gain access to the prostate through the urethra (B). The prostate material that has been restricting urine flow is cut off in pieces, which are washed into the bladder with water from the scope (B). (Illustration by GGS Inc.)

Other Information
Transurethral resection of the prostate (also known as TURP, plural TURPs and as a transurethral prostatic resection TUPR) is a urological operation. It is used to treat benign prostatic hyperplasia (BPH). As the name indicates, it is performed by visualising the prostate through the urethra and removing tissue by electrocautery or sharp dissection. This is considered the most effective treatment for BPH. This procedure is done with spinal or general anesthetic. A large triple lumen catheter is inserted through the urethra to irrigate and drain the bladder after the surgical procedure is complete. Outcome is considered excellent for 80-90% of BPH patients. Because of bleeding risks associated with the surgery, TURP is not considered safe for many patients with cardiac problems. As with all invasive procedures, the patient should first discuss medications they are taking with their doctor, most especially blood thinners or anticoagulants, such as warfarin (Coumadin), or aspirin. These may need to be discontinued prior to surgery. Postop complications include bleeding (most common), clotting and hyponatremia (due to bladder irrigation).
