Background: Among the most prevalent congenital abnormalities is hypospadias, a condition where the urethral opening is sited on the penis's ventral side. Evidence suggests that the incidence of hypospadias is on the rise. Having a penis that is functional and aesthetically normal for the boy is the surgical aim of hypospadias correction. Nevertheless, hypospadias surgery is still correlated with a great risk of complications, with a reported rate of 50% or more. Aim and objectives: This study aimed to determine the association among the pre-operative GMS score [glans (G), meatus (M), and penile shaft (S)] of boys with hypospadias and their postoperative hypospadias objective scoring evaluation (HOSE) score. Subjects and methods: This was a cross-sectional trail, in which, we enrolled 21 patients with hypospadias who presented to Pediatric Surgery Clinic, Suez Canal University hospital. The condition of the enrolled patients was assessed preoperatively by the GMS score and their postoperative outcomes were assessed by HOSE score. Results: Preoperative GMS scores and postoperative HOSE scores were not significantly associated with patients' characteristics. However, and more importantly, we found a significant positive connection among preoperative GMS score and postoperative HOSE score, where lower preoperative GMS score was associated with higher postoperative HOSE score. Conclusions: Hypospadias patients with severe conditions preoperatively, guided by GMS score, would have poorer postoperative outcomes, as assessed with HOSE scores.
