[A flowmetric study after a Mathieu-Righini intervention in medial-distal hypospadias].

Uroflowmetric long-term data (mean follow-up 4.5 years) of 64 nonselected patients successfully treated for mid-distal hypospadias with Mathieu-Righini procedure were analyzed. None of our patients needed meatal dilation after primary procedure. Four patients (6.3%) presenting a plateau pattern and a maximum flow rate less than -2 standard deviations were considered to have meatal obstruction. These patients were successfully treated with meatoplasty. We conclude that functional characteristics of the neourethra are quite equivalent to a normal urethra in most of boys and adolescents after meatal based flap urethroplasty. On the other hand, in order to prevent the possibility of unknown strictures postoperative uroflowmetric controls are strongly recommended.
