Abstract


Urethro-cutaneous fistula (UCF) is one of the most frequently seen complications of hypospadias surgery requiring reoperation; it occurs with an incidence of between 4% and 28%. Risk factors associated with the development of UCF can be classified as preoperative, intraoperative or postoperative. The aim of this study was to determine the association of perioperative risk factors and the development of urethrocutaneous fistula after hypospadias repair. A retrospective review of patients who had undergone hypospadias repair at Kenyatta National Hospital between 2013 and 2017 was conducted. 114 patient records were retrieved. The incidence of UCF was 47%. Risk factors that were significantly associated with UCF are hypospadias type (p=0.028), lack of a protective intermediate layer (p=0.002), and presence of postoperative complications (p=0.001). Age at surgery, suture material, type of repair and use of catheter/stents were not significant factors. Multivariate analysis showed wound infection and meatal stenosis as the most significant factors associated with UCF development.
