Objective: to compare, by means of a non-inferiority analysis, the prevalence of occurrence of major postoperative complications (urethrocutaneous fistula (UCF) and meatal stenosis) in patients operated on for distal hypospadias in a group with a urethral stent and another without it during the postoperative period.
Materials and methods: this is a randomized, controlled clinical trial. Patients (0 to 14 years) requiring intervention for distal hypospadias were randomized to the "with stent" group (group C) or "without stent" group (group S). Variables were collected during the pre-surgical visit, during hospital admission and after discharge. The main variables are major postoperative complications (UCF and meatal stenosis). Results: no statistically significant differences were obtained in the descriptive variables between the groups, so they are statistically comparable. No statistically significant differences were observed in the major postoperative complications or in the rest of the minor complications measured during follow-up. Statistically significant differences were found in the frequency of baldder spasms (14% group C, 0% group S, 7% not recorded; p= 0.02), in the administration of postoperative anticholinergic drugs (68% group C, 0% group S; p < 0.001), in the duration of antibiotherapy (intraoperative dose in 95% group S, 48 h in 90% group C and 72 h in 5% group C, not recorded in 4%; p < 0.001), in the presence of dysuria during admission (45% group C, 10% group S, 5% not recorded; p = 0.01) and in the duration of admission (median 57 h group C, median 12 h group S; p < 0.001).
Conclusion: in the present study, dispensing with urethral stenting in the postoperative period for distal hypospadias does not increase the rate of postoperative complications, making it a safe practice. In addition, it has other advantages such as the reduction of postoperative dysuria, of the drugs and morbidity (bladder spasms) associated with stent use and of the duration of hospital stay, with the consequent reduction of costs. Following these results, a paradigm shift in the management of distal hypospadias is recommended, since it is not necessary to use a urethral stent after the intervention.
