Abstract:
Objective:To evaluate the effect of urethral stent tube irrigation in preventing postoperative complications in adolescents with hypospadias.Methods:A retrospective analysis was conducted using the clinical data of adolescents with hypospadias treated at the Department of Urology, Children’s Hospital of Chongqing Medical University, from April 2016 to July 2023. Patients were divided into control group and study group according to whether urethral stent tube was inserted in urethra during operation. All surgeries were performed by the same surgeon. For two days before surgery, patients were instructed to cleanse the surgical site daily with body wash and a 5% povidone-iodine solution. In the control group, patients received postoperative care with an indwelling urinary catheter. In the study group, in addition to the urinary catheter, a urethral stent tube was placed in the posterior urethra, and postoperative urethral irrigation with saline was performed. Postoperative complications, including wound infection, urethral fistula, urethral stricture, and urethral diverticulum, were monitored. Categorical data were expressed as frequencies and percentages and were analyzed using the χ2 test or Monte Carlo-based χ2 test. Continuous data with normal distribution are presented as Mean±SD and were analyzed using the t-test. Non-normally distributed continuous data were expressed as M ( Q1, Q3) and were analyzed using the Wilcoxon rank-sum test. P<0.05 was considered statistically significant. Results:A total of 76 patients were enrolled in the study, with 43 patients in the control group [median age 12.9(12.2, 13.7) years, reconstructed urethral length (3.88±1.86) cm] and 33 patients in the study group [median age 12.5(11.3, 14.1) years, reconstructed urethral length (3.30±1.45)cm]. Postoperatively, 32 patients (74.4%) in the control group experienced complications, including 24 cases (55.8%) of wound infection, 16 cases (37.2%) of urethral fistula, 6 cases (14.0%) of urethral stricture, and 2 cases (4.7%) of diverticulum. In the study group, only 1 patient (3.0%) developed both wound infection and urethral fistula. The incidence of wound infection, urethral fistula, and overall complications was significantly lower in the study group than in the control group (all P<0.01). Conclusion:Postoperative urethral stent irrigation in adolescents with hypospadias significantly reduces the incidence of wound infection and urethral fistula.
