Onlay Urethroplasty with Parameatal Foreskin Flap for Distal Hypospadias

Experience with One-Stage Repair of Severe Proximal Hypospadias: Operative Technique and Results

“…Our complication rate of 40% is certainly higher than that of distal hypospadias where less than 5% required a secondary procedure [15], but not as high as our own complication rate of multistaged repair for severe hypospadias [18], and others are more candid by reporting an even higher chance (50%) of requiring a sec ondary or more operations in their experience with Duck- …”

“…In all these children dartos mobilization alone was insufficient to correct the chordee, unlike the majority of distal hypospadias [15], To complete chordee release after urethral detachment from the corpora, it was necessary to incise the intercorporal septum in 5 cases and to plicate the dorsum of the penis in 2 cases.…”

Measurement of Blood Flow in the Parameatal Foreskin Flap for Urethroplasty in Hypospadias Repair

“…In the 15 cases with distal hypospadias, a flip-flap technique [8], which we call one-stage urethroplasty with parameatal foreskin flap (OUPF) I, was employed in 1 patient and a meatal-based manta-wing flap [6], which we call OUPF II, was used for the other 14 patients. In the 15 cases with proximal hypospadias, we used the parameatally based and fully extended circumferential foreskin flap for urethro plasty [7], which is called OUPF IV.…”

“…In the 15 cases with proximal hypospadias, we used the parameatally based and fully extended circumferential foreskin flap for urethro plasty [7], which is called OUPF IV. The details of the operative pro cedure have been described elsewhere -OUPF I [8], II [6], and IV …”

“…The parameatal foreskin flap, both in the form of a manta-wing and in extended circumferential form, appears to have an enough microcirculation suitable for one-stage repair (OUPFII and OUPF IV, respectively) of hypospadias. bility of parameatal-based foreskin flap by assessing its microcirculation during our one-stage repair of hypospa dias [6,7], …”
