VESICOVAGINAL
FISTULA
GICHANA ELVIS
INTRODUCTION
Definition.
A VVF IT is an abnormal communication between the
epithelium of the urinary bladder and vagina.
Prevalence.
 Affects about 2 millions women, almost all in
developing countries, particularly in Africa and the
Indian sub-continent.
Risk factors
I. Hereditary contracted pelvis.
II. Early marriage-pelvis is not yet fully matured.
III. Malnutrition-pelvis tends to be of a small build.
IV. Poor access to emergency obstetric care.
V. Low socioeconomic status-women with VVF
come almost exclusively from poor families.
VI. Acquired contracted pelvis- accident/traumatic
, infections like polio or TB.
Classification
According to anatomicphysiologic location.
1:Not involving the closing mechanism
2:Involving the closing mechanism.
A:without(sub) total urethra involvement.
without circumferential defect.
with circumferential defect.
B:with(sub) total urethral involvement
without circumferential defect.
with circumferential defect.
3.Miscellaneous, eg. Ureter and other
exceptional fistulas.
Further classification according to
size.
Small <2cm
Medium 2-3cm
Large 4-5cm
Extensive 6cm.
ETIOLOGY.
v 1)Direct trauma.
 During obstetric or gynecological
operations the bladder may be
accidentally injured.
 During c/section, hysterectomy,
forceps delivery, craniotomy.
Cont..
2)Obstetric injury
Prolong obstructed labor-ischemic necrosis.
Symptoms are seen 3-10 days post delivery.
3)neoplastic fistula.
Cancer of the cervix- stage IV.
Cancer of urinary bladder.
Cancer of the vagina.
Cont..
4)infections.
Granulomatous infections like TB
,Syphilis,Schistosomiasis
5)radiation.
Clinical features
Total urine incontinence
Urine -induced dermatitis,
ulcerations.
Pelvic bone pain
Foot drop, unsteady gait.
Clinical and social consequences of VVF.
Bladder prolapse, stone formation,
Loss of pelvic muscles tone.
Vaginitis, UTI,
Partial or complete loss of the labia
minora/ vagina, varying from loss of the
anterior vaginal wall to vagina stricture,
circular stenosis and even atresia.
Social and psychological pain
Possible future inability to become
pregnant.
History.
Is the leakage involuntary? Any urge to
micturate?
Antenatal review:
 Booking time, where? Who was
attending her?
 Any risk factor identified?
 How far is the clinic from her house?
Cont…
Labor:
 Onset of labor, when, where?
 At what time did the membrane
rupture?- possibility of infection.
 Duration of labor.
 Where did she delivered?
Cont..
Mode of delivery
Condition of the baby at delivery.
Condition of the mother.
Postdelivery
Was she catheterized?
H/o fever
When was the leakage first noticed?
Urge to micturate.
Weakness of the lower limbs.
Examinations
General:
Height- those less than 150cm are at increased
risk of cephalopelvic disproportion.
Gait: peripheral neuropathy due to compression
of nerve during prolong and obstructive labor.
CNS:-exam the lower limbs for tone, power,and
reflexes.
Pelvic examination
Inspection: ammoniac smell?
any presence of excoriation on the
vulva or perineum.
Digital examination:palpate the vaginal wall
to feel any defect or fistula margin.
Speculum:using Sims speculum, inspect
any presence of fistula, note the
size and position of fistula.
Management.
Immediate management of fresh fistula.
1)urethral catheterization:
40-60% of small fistula heal following 4-6 weeks
of catheterization.
2)antibiotics:
In case of an obstetric fistula antibiotic is not
needed since is due to pressure necrosis,
unless there is evidence of infection.
3)plenty of fluid, minimum of 6-8L/day.
4)oral hematenics and high proteins diet.
Cont..
5)Debridement of the slough/necrotic
tissues.
6)Early closure.
PREOPERATIVE MEASURES.
1)Plenty fluid; why?
 Prevents recurrent UTI.
 Prevents stone formation
 Minimizes ammoniac smell.
2)Hb levels, urinalysis.
3)Hematenics and high protein diet to speed up
recovery.
4)Preoperative EUA-controversial. Some surgeons
prefer doing at the same time of repair.
Time for repair.
Early repair:
No need of waiting for 3 months.
A fistula is a stigma with psychological
impact,it is for the patient to do early
repair.
Early repair has been reported to have
excellent success rate as to closure and to
continence and thus preventing the patien
from becoming an outcast.
Delayed repair:
No remaining necrotic tissues.
The wound has healed and well
vascularized.
Fistula has regressed to the smallest size.
Patient is in good condition for operation
and anesthesia.
Operation/fistula repair.
1)position:
Exaggerated lithotomy position with legs
flexed and slightly abducted in stirrup.
Knee chest position.
2)approach:
Transvaginal-recommended for almost all
repairs.
Cont..
Transabdominal-transvesical approach-when
the fistula margins are near the ureteric orifices
requiring a transvesical catheterization of the
ureters, mobilization of the bladder mucosa and
close without compromising the ureters.
Indicated also for large fistula with contracted
bladder.
3) Fistula exposure
Adequate exposure is emphasized.
May need episiotomy uni-or bilateral or
Schurchardt incision in case of tight
vaginal outlet.
4)avoid the bladder mucosa and tension on
the bladder wall.
5)excision of the fistula tract.
6)repair East-westerly direction.
POSTOPERATIVE CARE
1)Encourage plenty of fluid.
2)indwelling catheter at least 2 weeks.
3) Input -output ,monitoring.
4)antibiotics-controversial
5)oral hematenics
6) Start ambulation,bladder training on day
2.
Cont..
7) Day 14:dye test.
If negative-remove catheter, encourage
to pass urine every 15 min.,avoid sex.
If positive-change catheter, retain for
another 4 weeks then repeat dye test.
Follow up:
Review her 2 weeks after removal of
catheter, then 1 month later, then 2-3
months, can resume sexual activities.
Enquire for leaking(incontinence)
Check for healing,stress incontinence.
POSTOPERATIVE COMPLICATIONS.
Early complications
Postoperative death-due to pulmonary
thromboembolism, urosepsis.
Blockage of the catheter.
Urine retention
Vaginal stenosis/atresia.
Late complications
Stress and/ urge incontinence
Overflow incontinence.
Fistula recurrence.
Bladder stone formations.
A successful fistula repair.
1)maintance of urine continence.
2)ability to hold urine up to 150-
160mls.
3)ability to perform sex and enjoy.
4)resumption of conception and
ability to bear a child.
Future deliveries.
Mode of delivery is mainly by
c/section.
PREVENTION.
Primary.
Prevention of prolong and obstructed
labor.
Education to women-ANC
attendance,hospital delivery.
Economy-alleviate poverty.
Socially-decision making power,abandon
early marriage.
Cont..
Promotion of good health
Improve infrastructures
Improve health facilities and personnel
Secondary prevention
Following obstructed labor:
Intervene - c/section.
Post delivery bladder catheterization.
Antibiotics.
Tertiary prevention and rehabilitation.
Fistula has already occurred. Aimed at
providing good
environment for either spontaneous healing or
successful repair.
Measures for early treatment
Psychotherapy.
Delivery situation in the country:
45% is home delivery
55% is done in the health institutions
which include:
Dispensaries,maternity homes,health
centres,district hospitals,reginal
hospitals, and consultants hospitals.
cont..
Trained personnels are not enough or
lacking in many health centers.
The infrastructure is poor
