Purpose: Boys in whom hypospadias was repaired by tubularized, incised plate urethroplasty were evaluated to determine whether dorsal incision of the urethral plate results in strictures of the neourethra.
Materials and methods: Postoperative followup of the initial 72 patients was reviewed and then attempts were made to contact these boys for delayed assessment more than 1 year after surgery. Periodic neourethral calibration was routinely done during year 1 postoperatively and at delayed followup. Urethroscopy was performed for a decreased urinary stream or during anesthesia for other procedures. Uroflowometry was done at the delayed assessment of toilet trained boys.
Results: The urethra was calibrated in 85% of the patients with no strictures noted. Urethroscopy in 10% of the boys demonstrated a healthy appearing neourethra. Uroflowometry was possible in 34% of the toilet trained patients with all results within the 95% confidence levels of standard curves for age.
Conclusions: The dorsal relaxing incision of tubularized, incised plate hypospadias repair did not result in neourethral strictures.
