Impact of caudal regional anesthesia on complications after hypospadias repair with tubularised incised plate urethroplasty / 中华实用儿科临床杂志

ABSTRACT

Objective:To assess the impact of caudal regional anesthesia on complications after hypospadias repair with tubularised incised plate urethroplasty (TIP).Methods:A total of 125 cases with hypospadias undergoing TIP surgery from June 2017 to June 2019 at Beijing Children′s Hospital, Capital Medical University, were reviewed, aged 12-75 months, American Society of Anesthesiologists Ⅰ orⅡ grade.Totally, 86 cases had distal and 39 cases suffered from proximal hypospadias.Caudal anesthetics were used in 42 cases (caudal anesthesia group) and general anesthetics were used in 83 cases (general anesthesia group). All cases were repaired by TIP procedure.The children with urethral fistula and urethral stricture were followed up for 6 months, and multivariate statistical analyses were performed.Results:There were 11 cases of urethral fistula after hypospadias surgery, with 8 cases (9.64%)in the general anesthesia group and 3 cases (7.14%) in the caudal anesthesia group.There were no significant differences between the 2 groups ( χ2=0.223, P=0.636), and 12 cases of urethral stricture, with 8 cases(9.64%) in the general anesthesia group and 4 cases(9.52%) in the caudal anesthesia group.There were no significant differences between the 2 groups ( χ2=0.001, P=0.984). Based on multivariable Logistic regression, urethral fistula was associated with proximal hypospadias ( OR=0.036, 95% CI 0.003-0.511, P=0.014), and the width of glans( OR=0.469, 95% CI 0.220-0.998, P=0.049). Urethral stricture was correlated with proximal hypospadias( OR=0.004, 95% CI 0.000-0.146, P=0.002), the width of urethral plate( OR=0.004, 95% CI 0.000-0.422, P=0.020), and the duration of catheter( OR=72.976, 95% CI 1.802-2 594.790, P=0.023). Conclusion:Caudal regional anesthesia appears to have no impacts on urethral fistula and stricture after hypospadias repair.
