INTRODUCTION: Urethral stricture is the most common complication in hypospadias surgery. The monitoring of operated patients allows rapid detection of this complication and the uroflowmetry is the main diagnostic method.
OBJECTIVES: To study of functional results in patients who underwent distal urethroplasty, using uroflowmetry.
PATIENTS AND METHODS: A retrospective chart review was conducted of 81 patients who underwent distal hypospadias repair (7 coronal, 51 subcoronal and 23 distal penile shaft) and a postoperatory uroflowmetric study. The patients were divided into two groups, in each type of hypospadias, according to the presence or absence of stenotic complications (0 coronal, 10 subcoronal and 5 distal penile shaft). The functional effects in both groups were studied.
RESULTS: All patients with stenotic complications showed maximum flow rates and mean flow rates below 15 and 20 percentiles respectively and a plateauing layout of the urinary flow curve. The treatment of these conditions resulted in the normalization of the maximum flow values (in 100% of the subcoronal and 100% of the distal penile shaft hypospadias), as well as in the mean flow values (in 88% of the subcoronal and 75% of the distal penile shaft hypospadias). The curve also adapted a bell-shaped in 100% of the H. coronal and 50% of the H. distal penile shaft. The uroflowmetry presented a spontaneous improvement in all patients without stenotic complications but with low flows in their first uroflowmetric.
CONCLUSIONS: Uroflowmetry is an objective method for the evaluation of hypospadias surgery, being easy to perform, noninvasive and reliable. Obstructed uroflow patterns point to the presence of a stenotic complication.
