Membranous urethra spasms are involuntary contractions of the muscles surrounding the membranous part of the urethra. These spasms can cause discomfort, pain, and difficulty during urination. Understanding the causes, symptoms, and treatments can help manage and alleviate the condition effectively.
The urethra is a tube that carries urine from the bladder out of the body. In males, the urethra has several sections:
- Prostatic Urethra: Passes through the prostate gland.
- Membranous Urethra: The narrowest and shortest part, located between the prostate and the bulbous urethra.
- Bulbar and Penile Urethra: Extend through the penis.
The membranous urethra is surrounded by the external urethral sphincter, a muscle that controls urine flow.
Urethral spasms occur when the muscles around the urethra contract involuntarily. This can lead to a temporary blockage of urine flow, causing pain and difficulty during urination. Spasms can be triggered by various factors, including infections, injuries, or neurological conditions.
Pathophysiology of Membranous Urethra Spasms
Structure
The membranous urethra is a short segment of the male urethra, approximately 1-2 centimeters long. It is surrounded by the external urethral sphincter, which plays a crucial role in controlling urine flow.
Blood Supply
The membranous urethra receives blood primarily from the bulbourethral arteries and branches of the pudendal artery. Adequate blood supply is essential for maintaining the health and function of the urethral tissues.
Nerve Supply
Nerve supply to the membranous urethra comes from the pudendal nerve. This nerve controls the external urethral sphincter and is responsible for initiating and regulating muscle contractions.
Types of Membranous Urethra Spasms
- Acute Spasms: Sudden and severe contractions, often linked to infections or injuries.
- Chronic Spasms: Persistent or recurring spasms, possibly due to neurological disorders.
- Reflexive Spasms: Triggered by reflex actions, such as after catheterization.
- Psychogenic Spasms: Caused by psychological factors like stress or anxiety.
