PURPOSE
Tubularized incised plate urethroplasty is the most commonly used method for the treatment of
hypospadias. Its complication rate is reported to be between 3–33 %. The aim of this study is to
evaluate the usefulness of a newly developed objective scoring system to predict the development
of complications after TIPU.
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 hy-
pospadias between May 2011 and July 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
Three hundred and ninety-four patients (average age: 41.9±33.4 m, average follow-up:43.9±24.7 m)
were included. Complications were observed in 49 (12.4 %) patients. Those with complications had
a slightly higher but statistically significantly higher average score (9.02±2.09 vs 9.86±2.52, p<0.05.)
The cut-off value for optimal prediction of complications was determined as 10 with a negative pre-
dictive value of 90.4 %. The complication rate of patients who had 10 or fewer points was 11.1 %,
the complication rate for those with 11 or more points was 20.4 % (p=0.01).
CONCLUSIONS
Our objective scoring system was found to successfully predict complications after TIPU for hypo-
spadias repair. Patients with scores of 11 and above have statistically significantly more complica-
tions. This objective scoring system can be a guide surgeons who perform TIPU.
