ABSTRACT

PURPOSE:

To determine the role of uroflowmetry in the evaluation of the functional results of hypospadias repair we reviewed the asymptomatic patients who underwent hypospadias repair. MATERIALS AND

METHODS:

A total of the 34 patients was available for this study. Age of patient were ranged from 3 to 14 years(mean; 8.8+/-4.67 years) at the time of uroflowmetry and followup ranged from 7 months to 3.5 years(mean; 2.4+/-0.88 years) after repair of hypospadias. The peak uroflow were compared to age dependent nomograms that indicate the normal range of peak flows according to the voided volumes. Flow rates were defined as low if they decreased below 90 percentile of the expected normal range.

RESULTS:

The peak urine flow in hypospadias repair patients(12.1 +/-8.74m1/sec) was not significantly different from normal control(12.9+/-5.10 ml/sec). Five of the 34 patients had peak flow below the normal ranges. One of the 17 patients with chordee and one of the 11 without chordee showed low peak urine flow. One of the 14 patients with anterior hypospadias, one of the 8 with posterior hypospadias and none with mid hypospadias showed low peak urine flow. According to the methods of repair one of the 12 patients with onlay island flap, one of the 5 with pyramidal procedure and three of the 6 who had undergone previous attempts at hypospadias in other hospital showed low peak urine flow Two of the 5 patients who revealed low peak uroflow rate were managed with periodic meatal dilatation and the 3 were managed with internal urethrotomy for proximal urethral stricture.

CONCLUSIONS:

The uroflowmetry is an easy and noninvasive method to detect asymptomatic urethral stricture In hypospadias repair patients.
