A urogenital fistula is an abnormal connection between the urinary tract and the genital tract. It allows urine to leak from the bladder or urethra into the vagina, which can lead to continuous leakage of urine and cause discomfort, infection, and hygiene issues.
Pathophysiology of Urogenital Fistula
Pathophysiology refers to how a disease or disorder affects the body’s normal function and structure.
Structure Involved in Urogenital Fistula:
- Bladder: The muscular organ that stores urine.
- Urethra: The tube that carries urine from the bladder to the outside.
- Vagina: The female reproductive organ.
- Uterus: The organ where a baby grows during pregnancy.
- Rectum: Part of the digestive system that stores feces.
- Perineum: The area between the vagina and rectum.
Blood Supply:
- The bladder, urethra, and vagina receive blood from branches of the internal iliac artery, such as the vesical, vaginal, and uterine arteries.
- Good blood flow is essential for healing tissues and preventing fistula formation.
Nerve Supply:
- The bladder and urethra have nerve supply from the autonomic nervous system (sympathetic and parasympathetic nerves), which controls urination.
Types of Urogenital Fistula
- Vesicovaginal Fistula (VVF): A connection between the bladder and vagina.
- Urethrovaginal Fistula: A connection between the urethra and vagina.
- Ureterovaginal Fistula: A connection between the ureter (tube carrying urine from kidney to bladder) and vagina.
- Rectovaginal Fistula: A connection between the rectum and vagina.
- Urethrocutaneous Fistula: A connection between the urethra and the skin.
- Colovesical Fistula: A connection between the colon and bladder.
