Abstract Objectives: To objectively assess the functional and cosmetic outcomes of
a modified tubularised incised-plate (TIP) urethroplasty (Snodgrass) technique, with
particular attention to the uroflowmetry study and Hypospadias Objective Scoring
Evaluation (HOSE) score.
Patients and methods: In a prospective case-series study, 43 consecutive patients
with primary distal hypospadias were evaluated. The modified Snodgrass technique
included an extension of the midline relaxing incision of the urethral plate from
within the hypospadiac meatus to the very tip of the glans. The neourethra was tubularised
starting at the neomeatus and proceeding proximally. The neourethra was
covered with either a single or double dartos flap. In toilet-trained boys, at least
3 months after surgery, the flow pattern, maximum (Qmax), and mean urinary flow
rate (Qave) were recorded, and the results plotted against a recently published
flow-rate nomogram from normal children. The postvoid residual urine volume
was measured using ultrasonography. The cosmetic outcome was assessed using
the HOSE system.
