Urethral stricture refers to a narrowing of the urethra, the tube that carries urine from the bladder out of the body. Urethral lacunae stricture specifically involves areas within the urethra called lacunae—small recesses or spaces—that become narrowed or blocked.
Pathophysiology
Pathophysiology is the study of how normal bodily functions are altered by disease.
Structure of the Urethra
- Male Urethra: About 20 cm long, passing through the penis and prostate.
- Female Urethra: Shorter, about 4 cm, located above the vaginal opening.
Blood Supply
- The urethra receives blood from branches of the internal pudendal artery, ensuring it gets necessary nutrients and oxygen.
Nerve Supply
- Sensory and motor nerves control the urethra, facilitating urination and maintaining continence.
Urethral lacunae stricture occurs when scar tissue forms within the urethral lacunae, leading to narrowing. This restricts urine flow, causing various urinary problems.
Types of Urethral Lacunae Stricture
- Anterior Stricture: Located in the front part of the urethra.
- Posterior Stricture: Found in the back part, near the bladder.
- Bulbar Stricture: Occurs in the bulbar section of the male urethra.
- Penile Stricture: Located in the penile part of the urethra.
