title: Regular dilatation is unnecessary after tubularized incised-plate hypospadias repair.
abstract: OBJECTIVE
  To determine if patients who undergo tubularized incised-plate (TIP) urethroplasty need regular dilatation to prevent neourethral strictures or meatal stenosis.
  
  
  METHODS
  The follow-up of two consecutive series of patients who underwent primary TIP hypospadias repair by one surgeon was reviewed. The first 72 patients (group 1) had periodic neourethral calibrations for 1 year after repair, while the next 62 patients (group 2) had no routine dilatation, except for six patients (10%) in whom the meatus appeared to be small. Urethroscopy was performed in both groups at the time of fistula repair, skin revisions or during anaesthesia for unrelated procedures.
  
  
  RESULTS
  There was no evidence of scarring in group 1; one case of meatal stenosis and one neourethral stricture were detected in group 2. The difference in outcome was not statistically significant (P = 0.4). Overall, the incidence of meatal stenosis was low (0.7%) and comparable with most recent series in which postoperative calibration was not used routinely.
  
  
  CONCLUSIONS
  Dilatation of the neourethra is unnecessary after TIP urethroplasty. Calibration or uroflowmetry 6 months after surgery may be useful to detect subclinical obstruction.
