EXPERIENCE WITH MANAGING CHILDHOOD URETHROCUTANEOUS FISTULA AT IBADAN

Urethrocutaneous fistula could be a distressing condition to the child and parents alike. Its management could be challenging and requires adequate expertise.

To review the characteristics and aetiology of urethrocutaneous fistula managed in our division over a ten-year period.

All children with urethrocutaneous fistulae from July 2006 to June 2015 were subject of this review. The demography, aetiology, type of fistula, operation performed and the outcome were retrieved from the division operation book and case notes of the patients. The data was analyzed using SPSS Inc. version 20 and odd ratio.

Thirty-five children were managed over a period of ten tears. The age ranged from 6 months to 13 years with a mean of 4±1.9years. Seventy one percent of urethrocutaneous fistulae resulted from complication of childhood male circumcision procedures performed in private hospitals and by nurses. One child (3%) had isolated perineal urethrocutaneous fistula while 26% complicated hypospadias repair at these locations: glandular in 1% case, subcoronal in 3% cases, penile in 2% cases, and penoscrotal in 3% cases. Ten (29%) children with abnormal haemoglobin AC was noted in 3 (9%) patients and haemoglobin AS in 7 (20%) patients. The odd ratio between abnormal haemoglobin and normal haemoglobin was 3.8. The surgical repair of post-circumcision urethrocutaneous fistulae and post-hypospadias had a recurrent fistulae in 4 (16%) and 3 (33%) respectively. Majority of the fistulae were repaired by simple closure in 80% post-circumcision and in 44% post-hypospadias repair. in the more difficult cases, penile degloving with urethral mobilization was done in 16% post-circumcision fistula and 22% post-hypospadias fistula with no recurrence.

in this study, post-circumcision urethrocutaneous fistula was the commonest cause of childhood urethrocutaneous fistula, the severe ones could require penile degloving to achieve repair without tension; recurrence was a major complication.
