Oral Antibiotic Use Following Stented Hypospadias Repair: Does It Play a Role in the Prevention of Urinary Tract Infections?

[摘要] Background: There is a lack of consensus regarding the role of oral antibiotics following hypospadias repair. Objectives: The study aimed to evaluate the role of oral antibiotic use following stented Tubularized incised plate urethroplasty (TIPU) in the prevention of bacteriuria and urinary tract infections (UTIs). Methods: A prospective study was conducted on 40 patients undergoing stented TIPU for coronal hypospadias between January 2014 and December 2016. The average age of the subjects was 13.2 months at the time of surgery, ranging from 11 to 16 months. The patients were divided into two groups. Group A consisted of 20 patients receiving oral antibiotics until urethral catheter removal, whereas group B consisted of 20 patients without any oral antibiotics postoperatively. Results: The two groups were followed for three years. The urethral catheter was removed eight days postoperatively in the two groups. In group A, the patients received oral antibiotics as long as the catheter was left in situ. Urine samples were collected from the patients and sent for analysis and culture at the time of stent removal and after three weeks. The results showed that 3/20 (15%) patients from group A had pyuria and bacteriuria, while all of them had negative urine culture results. On the other hand, in group B, 8/20 (40%) patients had pyuria and bacteriuria (P > 0.05), and four (20.0%) patients had positive urine cultures for Escherichia coli (P < 0.05), sensitive to co-trimoxazole. None of the patients in the two groups had febrile UTI. Conclusions: The use of oral antibiotics for patients following stented TIPU reduces pyuria and significantly decreases positive urine culture results and the risk of UTI after surgery.
