The urological problems of micturition in children operated upon for hypospadias have often been overlooked. Flowmetry and urethral profile provide two helpful urodynamic parameters for evaluating the functionality of the urethral canal. We have carried out 75 urodynamic tests on 48 children aged between 2 and 13 yrs; of these, 42 had been operated for hypospadias with the one-stage preputial island-flap technique and presented a follow up of 17 yrs, 6 children had been operated with different techniques; 27 children were studied pre-operatively. All the children underwent the flowmetric study, while in 12 cases a study of the urethral pressure profile was carried out. A low flow was found in 20 out of 27 cases of non-operated children, of these 13 out of 27 (= 48%) were below physiological limits, acording to Gierup parameters. In the cases operated with the island-flap technique, the post-operative flow appeared within normal limits in 43 out of 48 cases (approx. 80%). Flowmetry is a simple method, non-invasive and precise in evaluating the urinary flow even in the child. The urethral profile carried out in 12 cases revealed normal morphology in most of the reconstructed urethras - in 3 cases a stenosis could be demonstrated.
