All patients received standard penile straightening and tubularized incised plate (TIP) urethroplasty. Patients in the study group (n = 53) additionally received intraoperative autologous PRP injections, whereas the control group (n = 50) did not. Outcomes analyzed included operation time, postoperative ambulation time, pain scores, length of hospital stay, incision infection rates at postoperative day 7, surgical success rates, and incidence of complications within 2 years postoperatively. Statistical analyses incorporated 95% confidence intervals (CIs), effect sizes (Cohen's d and relative risk, RR), and multivariate logistic regression analyses adjusting for potential confounders such as patient age and hypospadias severity.ResultsNo significant differences were observed between groups regarding operation time, postoperative ambulation time, or length of hospital stay (p > 0.05). Patients in the PRP group experienced significantly reduced postoperative pain (mean difference −2.14; 95% CI: −2.46 to −1.81; p < 0.001; Cohen's d = 2.35) and notably lower incision infection rates on postoperative day 7 (RR = 0.13; 95% CI: 0.03–0.60; p = 0.006). Surgical success rates were significantly higher in the PRP group compared to controls (94.3% vs. 72.0%; RR = 1.31; 95% CI: 1.09–1.58; p = 0.002). Multivariate logistic regression analysis confirmed that PRP injection remained independently associated with a significant reduction in postoperative complications after adjusting for age and severity of hypospadias (adjusted OR = 0.14; 95% CI: 0.04–0.52; p = 0.003).ConclusionAdjunctive autologous PRP treatment in pediatric penile hypospadias repair effectively alleviates postoperative pain, enhances wound healing, significantly reduces short-term complications, and improves surgical success rates. Future randomized, multicenter trials with extended follow-up periods are required to further evaluate long-term outcomes and to compare PRP efficacy directly with other biomaterials used in urethroplasty.
