Abstract
Objective: Hypospadias is a common genitourinary system (GUS) anomaly in boys occurring in 1 of 200 to 300live births. Undescended testes is frequently detected among accompanying anomalies in cases with hypospadias.Especially in proximal hypospadias and bilateral cases, this association may indicate sexual differentiation disorders. Theaim of the study was to evaluate the togetherness of additional anomalies in hypospadiac children with undescendedtestes.
Material and Methods: Between 2007 and 2016, data of 392 children who underwent surgery for hypospadias wereevaluated retrospectively. Urethral meatus was present at scrotal and penoscrotal in 65 cases (16.6%) and glanular,coronal, subcoronal and midpenile in 327 cases (83.4%). The cases were divided into two groups as those with bothtestes in the scrotum and those with undescended testes, and the anomalies were recorded.
Results: The mean age of the children with proximal hypospadias was 21 months (6-240 months). Of the childrenwith proximal hypospadias, 26 (40%) had undescended testes and 39 (60%) had testes in the scrotum. Undescendedtestes were detected bilaterally in 17 patients (65.4%) and unilaterally in nine patients (34.6%) in the undescendedtestes group. In the undescended testes group, 24 patients (92.3%) had suspected external genitalia (bifid scrotum,penoscrotal transposition, togetherness of micropenis and penoscrotal hypospadias, scrotalized labium majus) onphysical examination. In the undescended testes group, three patients (11.5%) had additional urinary pathology andten patients (38.5%) had other system anomalies. Ten patients (25.5%) had suspicious external genitalia on physicalexamination in the proximal hypospadias group who had both testes in scrotum. Additional urinary pathology wasdetected in one patient (2.5%) while other system anomalies were detected in five (12.8%) patients.The mean age of children with distal hypospadias was 33 months (6-156 months). Nine of 327 children with distalhypospadias (2.8%) had undescended testes. Of these, five were bilateral (55.6%) and 4 had unilateral undescendedtestes (44.4%). None of the patients with distal hypospadias had any suspicious genitalia on physical examination. Inthe undescended testes group, one patient (11.1%) had additional urinary pathology and one patient had other systemanomaly. Seven patients (2.2%) who had both testes in scrotum had additional urinary pathology and 32 patients (9.8%)had other system anomalies.
Conclusion: According to our results, further tests such as genitourinary ultrasonography, pelvic MRI if necessary,endocrine and genetic evaluation should be considered in cases where the proximal hypospadias is accompanied byan undescended testicle, and detailed anamnesis and physical examination covering all systems is necessary in allhypospadiac children in terms of additional anomalies.
