  • Purpose: We describe the functional outcome following tubularized incised plate repair of hypospadias in toilet trained children after an intermediate followup.
  • Materials and Methods: Children were included in this study only if they were toilet trained and had flow rate data not less than 6 months after primary tubularized incised plate hypospadias repair or 2 months after any secondary procedure to correct complications. Uroflow data (peak flow, voided volume and post-void residuals) were analyzed and plotted on previously determined age-volume dependent nomograms.
  • Results: Of the 48 boys, 39 required no secondary procedures, while 9 secondary fistula closures were performed in 2, meatotomy in 2 and dilation in 5. After either primary (n = 26) or secondary (n = 7) procedures 33 of the 48 patients (68.7%) had normal peak flow rate and 15 (31.3%) had low peak flow rate. Of the 48 patients 46 had post-void residual urine less than 10% of voided volume.
  • Conclusions: Most children will void efficiently with no straining and no post-void residual (1/2) to 4 years after tubularized incised plate hypospadias repair. Of our patients 68.7% have normal peak flow rate. Intermediate followup of larger series and followup at puberty are recommended to resolve the debate concerning the long-term functional outcome of tubularized incised plate hypospadias repair.

  • Editorial Comment
    This paper attempts to evaluate the functional outcome of the incised plate hypospadias repair. In my mind, the data are incomplete; however, the authors do find that the majority of patients had flow rates below the mean. Although these data would not yet convince me to give up this excellent repair, it does give pause and make us ever more aware that 6 month to 4 year followup is very insufficient for pediatric urological conditions.
