Pattern and Outcome of Iatrogenic Genitourinary Fistula from Obstetric and Gynaecological Surgeries in a Tertiary Institution, North-Western Nigeria | Chapter 04 | Emerging Research in Medical Sciences Vol. 1
Introduction:
Genitourinary fistula is commonly caused by prolonged obstructed labour;
however, not all genitourinary fistulas are obstetric in origin. Inadvertent
injuries to the urinary tract leading to fistulae do occur during obstetric and
gynaecological procedures because of the close anatomical relationship between
the urinary tract and the genital tract.
Objectives: This study aims to
determine the prevalence, aetiology and outcome of iatrogenic genitourinary
fistula repair at the National Obstetric Fistula Centre, Katsina (NOFIC).
Methodology: This was a two-year
retrospective review of all patients who had surgery for iatrogenic fistula
between 1st January 2015 and 31st December 2016 at NOFIC,
Katsina. All patient case notes on this procedure during the stated period were
retrieved and analysed.
Results: A total of 728
genitourinary fistula surgeries were carried out in the Centre, out of which
117 (16.1%) were repairs for iatrogenic fistulae, giving a prevalence rate of
16.1%. Only 110 case notes were eligible for analysis, giving a retrieval rate
of 94%. The mean age of the patients was 30.40 ± 8.39 years, and the modal
parity was 1. All presented with a history of continuous urine leakage, and 71
(64.5%) had a history of a previous caesarean section. The procedures that lead
to the development of the fistula were conducted at secondary healthcare
centres in 84 (87.5%) of the patients. The fistulae were a result of emergency
caesarean sections in 73.6% of the cases, yankan gishiri in 9.1%, caesarean
hysterectomies for ruptured uterus in 6.4%, elective caesarean sections in 4.5%
and gynaecologic hysterectomies in 5.4%. A diagnosis of vesicocervicovaginal
fistula (VCVF) was made in 62.7% of the cases, vesicouterine fistula (VUF) in
12.7% and ureteric fistula in various combinations in 10%. The abdominal route
was used for the repair in 20.9% of the patients. Intraoperative bleeding was
the commonest (21%) complication associated with vaginal repair of VCVF. At
discharge, 73.6% were successfully closed and continent, while 19.1% had
residual fistula.
Conclusion: The prevalence of 16.1%
found in this study was high, and the most common cause of iatrogenic fistula
was emergency caesarean sections. The majority of the causal procedures were
done at secondary healthcare centres; therefore, this study recommends adequate
training, mentoring and ongoing supervision of doctors conducting caesarean
sections and other gynaecological procedures in secondary health centres as
well as increased community education and involvement in preventing harmful
traditional practices like yankan gishiri.
