Voiding patterns of adult patients who underwent hypospadias repair in childhood.

OBJECTIVE: This study aimed at evaluating the voiding patterns of adult patients who underwent hypospadias repair in childhood.

METHOD: Following IRB approval 103 (22.7%) of 449 adult patients who underwent hypospadias repair between 1978 and 1993 responded to the following questionnaires: International Prostate Symptom Score (I-PSS) and Short Form 12 questionnaire (SF-12). Uroflowmetry (UF) was performed for all patients. The patients were divided into three groups according to the primary meatus localization. Group I had 63 patients (61.5%) treated for glanular hypospadias, group II had 19 patients (18.4%) treated for distal hypospadias, and group III comprised the remaining 21 patients (20.4%) treated for proximal hypospadias.

RESULTS: The mean ± SD I-PSS score for all patients who responded to the questionnaire was 2.3 ± 2.4, and UF was 21.1 ± 4.3 mL/s. The patients from groups I and III had fewer urinary symptoms compared with those of the group II: 1.3 ± 1.5, 5.5 ± 2.4, and 1.6 ± 1.4, respectively (p < 0.0001). With regards to UF, the patients from the groups I and III did better compared with those from the group II: 22.1 ± 4.1 mL/s, 18.91 ± 4.2 mL/s, and 20.11 ± 3.42 mL/s, respectively (p = 0.021) (Figure). The UF was better in patients with normal vs. abnormal IPSS (p = 0.0064). The physical component summary was 49.8 ± 10.3, 51.1 ± 3.6, and 46.4 ± 0.3 in groups I, II, and III, respectively. The mental summary component was 42.64 ± 4.1, 42.2 ± 2.4, and 39.89 ± 2.9 in groups I, II, and III, respectively.

CONCLUSIONS: Most of the adult patients who underwent hypospadias repair in childhood had normal or mild voiding disturbance, with no effects on their physical or mental status.
