The prostate gland is a crucial part of the male reproductive system. It is located below the bladder and surrounds the urethra, which carries urine from the bladder out of the body. The prostate has several lobes, one of which is the median lobe. When this lobe is injured, it can lead to various health problems, including urinary and sexual dysfunction.
The prostate is divided into several lobes. The median lobe is located at the center of the prostate, typically in the area closest to the bladder. An injury to the median lobe can affect the functioning of the prostate, leading to urinary and sexual problems. The injury might be caused by trauma, surgery, or other medical conditions affecting the prostate.
Pathophysiology (Structure, Blood, Nerve Supply)
The prostate is a small, walnut-sized gland that plays an important role in male reproduction. Its primary function is to produce seminal fluid, which nourishes and transports sperm during ejaculation. The prostate also helps control urine flow by contracting and relaxing muscles around the urethra.
- Structure: The prostate consists of the median lobe, lateral lobes, and the anterior lobe. The median lobe sits in the center and can obstruct the urethra if it enlarges or gets injured.
- Blood Supply: The prostate gets its blood supply from the internal iliac arteries and other nearby blood vessels.
- Nerve Supply: The prostate is innervated by the pelvic nerves, which control both the smooth muscle of the prostate and the surrounding muscles responsible for urination and ejaculation.
Types of Prostate Median Lobe Injury
- Acute Injury: Sudden trauma to the prostate, such as from an accident or medical procedure, causing immediate symptoms.
- Chronic Injury: Long-term damage from conditions like benign prostatic hyperplasia (BPH), where the median lobe grows and blocks the urethra.
- Post-Surgical Injury: Damage that occurs after prostate surgeries like transurethral resection of the prostate (TURP).
