The aim of this study is to develop a new objective scoring system to predict the development of complications after hypospadias surgery. MATERIAL AND METHODS The scoring system included glans diameter, groove, plate and meatal location plus the presence of chordee. For each factor, points of 1–3 (glans diameter, groove and plate) or 1–4 (meatal location or chordee) were scored (total between 5–17). Patients who underwent surgery for hypospa- dias between May 2011 and January 2017 with a minimum of 3-month follow-up were included. Prospectively collected data was analysed retrospectively. Patients undergoing two session repair were not included. Patients’ scores were compared with complications using ROC curves. The appropriate cut-off value was calculated using the Youden method. RESULTS Five hundred and twenty-three patients (average age: 42.0±33.7 m, average follow-up: 39.6±23.4 m) were included. Complications were observed in 51 (9.8 %) patients. The cut-off value for optimal prediction of complications was determined as 10 with a negative predictive value of 93.9 %. The complication rate of patients who had 10 or fewer points was 7.4 % (n=32/430), the complication rate for those with 11 or more points was 20.4 % (n=19/93) (p=0.0001). CONCLUSIONS This new objective scoring system was found to successfully predict complications after hypospa- dias surgery. Patients with scores of 11 and above have statistically significantly more complications. We believe this new objective scoring system will be a guide surgeons who perform hypospadias surgery.
