OBJECTIVES: The aim of this study was to critically evaluate distal extension of the midline urethral plate incision, extended tubularized incised plate (e-TIP) technique, with the standard TIP and investigating predictors of functional and cosmetic success.
METHODS: In a prospective study, consecutive patients with primary distal hypospadias presented for repair were randomized to undergo either extended TIP (e-TIP) or standard TIP (s-TIP) technique. Cosmetic outcome was evaluated postoperatively using Hypospadias-Objective-Penile-Evaluation (HOPE) score and measurement of ventral-glans-closure-length (VGCL) and meatal length (ML). Functional outcome was evaluated by maximal flow rate (Qmax), average flow rate (Qave), and postvoid residual urine (PVR). The effect of preoperative parameters on the outcome was assessed with regression analysis.
RESULTS: In all 94 cases, out of 110 randomized, were available for analysis. Forty-six in e-TIP group and 48 cases in s-TIP group with comparable preoperative demographics. Median (inter-quartile range) of postoperative total HOPE-score was 57(45-60) vs. 55(44-60) for e-TIP and s-TIP (p < 0.001), respectively. The mean (SD) ratio of VGCL/ML was 87% (26) versus 46% (12) for e-TIP vs. s-TIP, respectively (p < 0.001). Both complications and functional outcomes were comparable. Urethral plate (UP) width and the use of e-TIP technique were significant predictors of successful cosmetic outcome in regression analysis (p = 0.019 and p = 0.001), respectively.
CONCLUSION: Extension of midline urethral plate can potentially create a vertical slit-like meatus located at the glans tip without compromising the functional outcome, thus providing better cosmetic outcome compared with the standard technique. The UP width was a significant predictor of superior cosmetic outcome.
