“…Compared to distal hypospadias correction, PH correction is more challenging and is associated with a higher risk of complications, including postoperative complications such as urethral fistulas, anastomotic strictures, urethral strictures, urethral diverticula, glans dehiscence, and recurrence of penile curvature [ 6 ]. Such postoperative complications may necessitate additional surgery, resulting in considerable economic and psychological strain for the patients’ families and society at large [ 7 – 9 ].…”

Background Children with hypospadias are at risk of serious physical and mental health problems, including abnormal urination, sexual dysfunction, and infertility. The sole available treatment is the surgical restoration of genital appearance and function. Proximal hypospadias (PH) correction is more challenging and carries a higher risk of complications than does distal hypospadias correction, with a higher likelihood of postoperative complications requiring additional surgery, resulting in considerable economic and psychological strain for families. Herein, we aimed to identify factors associated with complications following one-stage PH repair with urethral plate disconnection. Methods We retrospectively analyzed data from 236 children who underwent PH repair at our center between December 2020 and December 2022. We collected information on age, surgical procedure, length of the reconstructed urethra (LRU), glans width (GW), ventral curvature, surgical approach, preoperative androgen use, suture type, presence of prostatic utricle, body mass index, season of surgery, anesthesia type, low birth weight, preterm birth, follow-up period, and complications. Surgical complications included urethral fistulas, urethral diverticula, anastomotic strictures, urethral strictures, glans dehiscence, and penile curvature recurrences. The study population was divided into complication and no-complication groups, and univariate and multivariate analyses were conducted. Results Of the 236 patients with PH who had a median follow-up of 10.0 (8.0, 14.0) months, 79 were included (33.5%) in the complication group and 157 were included (66.5%) in the no-complication group. In the univariate analysis, age (P < 0.001), LRU (P < 0.001), degree of penile curvature (P = 0.049), and PH with prostatic utricle (P = 0.014) were significantly associated with complications after PH repair. In the multivariate logistic regression analysis, LRU (P<0.001, odds ratio [OR] = 3.396, 95% confidence interval [CI]: 2.229–5.174) and GW (P = 0.004, OR = 0.755, 95%CI: 0.625–0.912) were independent factors influencing postoperative complications. The optimal LRU threshold was 4.45 cm (area under the curve, 0.833; sensitivity, 0.873; specificity, 0.873; P<0.001, OR = 3.396, 95% CI: 2.229–5.174). Conclusions LRU and GW are independent factors affecting PH complications. An LRU of < 4.45 cm and an increased GW can reduce the risk of complications.
