Uroflowmetry Parameter Evaluation of Post Urethroplasty Hypospadia Patients in Padang

Abstract

Introduction: Hypospadias is the result of an abnormal growth of penis in which the failure of the growth of urethral fold that resulted in the urethral meatus at ventral penis is located proximal from its normal position in glanular with or without chorde. The incidence of hypospadias is one per 250-300 birth of males. The management of this abnormality is urethroplasty, but this technique may cause short or long term complication. At the long term it is important to determine functional outcome of hypospadia urethroplasty since it has an impact in patient’s life in the future. One of the modality that can be used to evaluate the functional outcome of the surgical correction is uroflowmetry. Methods: This observational analytic study with cross sectional design was performed in patients who underwent surgery for hypospadias correction with urethroplasty without fistula complication. The sampling technique that used was consecutive. The Q-max and Q-ave of those patients were measured using the uroflowmetry examination, and post-void residual urine was measured using ultrasound. The study was held in June-July 2015. Data presented descriptively, then analyzed using the T-test, and consideredstatistically significant p < 0,05. Results: From 10 hypospadia patients that underwent urethroplasty and from 10 healthy controls comparable in general regarding gender, age, body weight and height, there were no significant difference in Q-max (p = 0,316), Q-ave (p = 0,288), and Post Void Residual Urine Volume (p = 0,686). Conclusion: Post-urethroplasty hypospadia patients have no significant difference in uroflowmetry parameters with the control group.
