PURPOSE
An objective measure for reconstructive surgeries is the ultimate dream for every surgeon. Our aim
was to assess the correlation between GMS score (Glans-Urethral Meatus-Shaft score), penile
measurements and risk of postoperative complications.
MATERIAL AND METHODS
Prospective study included children with a mean age of 3.28±2.61years having coronal, distal
or mid penile hypospadias. They underwent Tubularized incised plate (TIP) repair from 2015 to
2017 and were assessed preoperatively by measuring GMS score, penile length, glans width, peno-
scrotal length, urethral plate length and urethral plate length/penile length. Follow up for 3 months.
Step wise logistic regression model was used.
RESULTS
Mean age, GMS score, glans width, penile length, penoscrotal length, urethral plate length and
urethral plate length/penile length ratio were 2.9±2.1 years, 6.8±1, 1.2±0.1 cm 3[AS1] .8±0.8 cm,
7.4±1.1 cm, 1.1±0.3 cm, 30.32±9.11 respectively, in complicated patients.
There was a statistical significance difference between complicated and non-complicated patients
regarding GMS score, glans width, penile length, penoscrotal length, and urethral plate length/
penile length ratio.
Complication rate for patients with GMS score ≤ 6, glans width ≥ 14 mm, penoscrotal length ˃ 5 cm
was 37.5 %, 12.5 %, 12.5 % respectively. Patients with a GMS score ˃ 6, glans width ˂ 14 mm and
penoscrotal length ≤ than 5 cm was 62.5 %, 87.5 %, 87.5 % respectively.
Step wise logistic regression model demonstrated that an in increase in GMS score by one value,
patients probability of having a complication is 3 fold.
CONCLUSIONS
GMS score ˃ 6 is associated with a higher complication risk following TIP repair. Glans width ≥
14 mm, penoscrotal length ≥ 5 cm have lower complication rate. Penile length and urethral plate /
penile length ratio have a clinical utility and statistical significance in anticipating complication rate
in distal penile hypospadias patients.
