Objective: The aim of this study was to investigate additional anomalies in hypospadias.

Materials and Methods: Patients who were operated for hypospadias between 1998 and 2019 were divided into distal (glanular, coronal and subcoronal), penile (distal penile, midshaft and proximal penile) and proximal (penoscrotal, scrotal and perineal) groups according to the localization of urethral mea to elaborate on additional anomalies.

Results: Of the total 316 hypospadias cases, 73 (23%) had additional anomaly. The median age of the patients was 51 (min: 1, max: 192) months. 64% distal, 18% penile and 18% proximal hypospadias were defined in the patients. The incidence of additional anomalies has significantly increased in patients with penoscrotal and proximal mea (P=0.015). Inguinoscrotal pathologies were significantly higher in patients with distal (P=0.012) and proximal hypospadias (P=0.015). The most common additional anomalies were inguinoscrotal region pathologies (P<0.001) and it was more significant in patients with proximal hypospadias (P=0.017). The surgical age of patients with additional anomalies (Median: 36 months) was significantly lower than the group without anomaly (Median: 60 months) (P=0.04). There was no significant difference between urinary system pathologies and other system anomalies in terms of frequency and mea localization.

Conclusion: A detailed inguinoscrotal examination should be performed in patients with hyposapadias. There is no clear indication for the presence of concomitant urinary tract anomalies in hypospadias.
