A fistula involving the bladder can have one of many specific names, describing the specific location of its outlet: Bladder and intestine: "vesicoenteric", "enterovesical", or "vesicointestinal" [1] [2] [3] Bladder and colon: "vesicocolic" or "colovesical" [4] Bladder and rectum: "vesicorectal" or "rectovesical" [5]
The most direct consequence of an obstetric fistula is the constant leakage of urine, feces, and blood as a result of a hole that forms between the vagina and bladder or rectum. [20] This leaking has both physical and societal penalties. The acid in the urine, feces, and blood causes severe burn wounds on the legs from the continuous dripping. [21]
Vesicovaginal fistula, or VVF, is an abnormal fistulous tract extending between the bladder and the vagina that allows the continuous involuntary discharge of urine into the vaginal vault. [citation needed] In addition to the medical sequela from these fistulas, they often have a profound effect on the patient's emotional well-being.
In anatomy, a fistula (pl.: fistulas or fistulae /-l i,-l aɪ /; from Latin fistula, "tube, pipe") is an abnormal connection (i.e. tube) joining two hollow spaces (technically, two epithelialized surfaces), such as blood vessels, intestines, or other hollow organs to each other, often resulting in an abnormal flow of fluid from one space to the other.
Because bowel tissue aids in absorption, its use for an augmentation may result in metabolic imbalance and result in the need to monitor vitamin B12, bicarbonate, and chloride. [11] If bowel tissue is used to create an entirely new bladder, the resulting reservoir to hold urine is called a neobladder. [12]
Vesicouterine fistulas occur most commonly after lower segment caesarean sections (about 83-93% of cases). [2] The possible mechanisms by which vesicouterine fistulas occur following caesarean sections include undetected bladder injury during caesarean section, inadvertent placement of a suture through the bladder during the repair of the uterus and abnormal blood vessel connections following ...
Abnormal passageways or fistulas can exist between the vagina and bladder, ureters, uterus, and rectum with the resulting passage of urine from the vagina, or intestinal gas and feces into the vagina, in the case of a vaginal–rectal fistula. [1] These vaginal fistulas are named according to the origin of the defect: vesicovaginal; urethrovaginal
Rectovaginal fistulas are often the result of trauma during childbirth (in which case it is known as obstetric fistula), with increased risk associated with significant lacerations or interventions are used such as episiotomy or operative (forceps/vacuum extraction) deliveries [2] or in situations where there is inadequate health care, such as in some developing countries.
