In this study we aimed to detect and draw attention to corresponding lower urinary tract obstructions in hypospadias patients by using uroflowmetry measurements. After obtaining written consents, totally 63 patients whom were performed hypospadias surgery and post op monitoring between january 2012 and january 2013, enrolled in our study. Pre and post op comparison of some uroflowmetry parametres including; mean urinary flow rates, duration to reach utmost urinary flow, urinary flow duration, duration of urinary decharge, post voiding residual volume and features of flow curves were conducted according to the literatural datas. We offer uroflowmetry examination as an easy to use, cost effective and non invasive test  for  revealing any corresponding lower urinary tract obstructions in hypospadias surgery performed patients. It also enables early diagnosis of such obstructions in mid term and long term follow up.
