| Objective To analyze retrospectively the factors that relate with urinary fistula after urethroplasty, summarize the treatment experience about congenital hypospadias, improve the cure ratio of surgery, so can reduce the incidence on urinary fistula.Methods To collect 203 cases about urethroplasty from August 2006 to August 2008 at pediatric surgery in our hospital, because urinary fistula usually takes place after postoperative two weeks, by observing the children urinating after the catheter be pulled out can we know whether urinary fistula happens or not, by telling a small number of children who had urinary fistula out of the hospital to come back can we get the informations of urinary fistula too. The way of follow-up is to collect the message at discharge and when return one month after discharge. By analyzing the 11 factors that relate possibly with urinary fistula, and through statistical analysis to obtain the relevant factors of urinary fistula.Results There were 69 cases among 203 cases of children with urethroplasty appearing postoperative urinary fistula, the incidence is 33.99%. By statistically analyzing the 11 factors of the possible impact on urinary fistula with the way of many factors of non-conditional logistic regression analysis, the result is that hypospadias degree, to use preoperative HCG and wound healing have significant correlation with the occurrence of postoperative urinary fistula, and the higher the degree of hypospadias, preoperative use of HCG and the worse the wound to heal, the more risk of urinary fistula.Conclusion The incidence of urinayt fistula after urethroplasy has significant correlation with hypospadias degree, preoperative HCG treatment and postoperative wound healing, the higher the degree of hypospadias, preoperative HCG treatment and the worse the postoperative wound to heal, the greater risk of urinary fistula, so we should pay more attention to combination treatment. |
