Cosmetic and functional outcomes of two-stage hypospadias repair: an objective scoring evaluation and uroflowmetry

Objective: The functional outcome following hypospadias repair is as important as the cosmetic outcome. Currently, structured scoring systems, patient questionnaires and evaluations of photographs and uroflowmetry are used to assess the results of hypospadias repair. In the present study, we assessed the outcomes of two-stage hypospadias repair using Hypospadias Objective Scoring Evaluation-HOSE and measures of uroflowmetry. Material and methods: Over a period of eight years, from January 1997 to December 2004, 126 hypospadias patients were treated, 90 of these patients received two-stage repairs and 36 patients received singlestage repairs. HOSE questionnaire and uroflowmetry data were obtained to evaluate the long-term outcome of the two-stage hypospadias repairs. Results: The age at the time of assessment ranged from 8 to 23 years-old, with a mean follow-up time of 39.78 months. Thirty-five patients had proximal hypospadias, and 20 had distal hypospadias. Of the 55 patients who received complete two-stage hypospadias repair and agreed to participate in the study, nineteen patients had acceptable HOSE scores and 36 patients had non-acceptable scores. The uroflow rates of 43 of the subjects were below the fifth percentile in three patients, equivocal (between the 5th and 25th percentile) in four patients and above the 25th percentile in 36 patients. Conclusion: Two-stage repair is a suitable technique for all types of hypospadias with varying outcomes. HOSE and uroflowmetry are simple, easy, non-invasive and non-expensive tools for objectively assessing the long-term outcomes of hypospadias repair.
