A comparative study on the uroflowmetry parameters between single stage and staged hypospadias repair.

Hypospadiasis defined as the opening of meatus on the ventral side of the shaft of thepenis. Until today there are more than 300 different surgical techniques withseveral modifications. Urethral stricture, urethral stenosis, urethrocutaneousfistula, chordee, are some of the few delayed complications after hypospadiassurgery. Urethral stenosis is a common complication and can lead to long termeffects on the bladder which can even potentially end in chronic kidneydisease. Uroflowmetry is a simple easy to use noninvasive test which can beused for the early diagnosis of urethral stenosis / stricture emerging afterhypospadias. Usually in staged hypospadias repair there is long length ofneourethra created. It can provide resistance to urine flow compared to smalllength in single stage hypospadias repair. We in this study aim to compare theuroflowmetry parameters after single stage and staged hypospadias surgery donein our institute. We also propose to find out any difference in theuroflowmetry values in the follow-up of hypospadias operated as single stageand staged repair.
