Radical bulbar dissection to correct severe chordee and proximal hypospadias.
OBJECTIVE
We describe a technique of proximal hypospadias correction that involves freeing the proximal normal bulbar urethra from perineal attachments to lengthen the ventral penis and decrease chordee.


METHODS
Correction was performed in 9 patients with a mean age of 11.5 months who had proximal hypospadias and severe chordee that was perineal in 2, mid scrotal in 6 and penoscrotal in 1. After the penis was degloved the bulbar urethra was detethered to or beyond the perineal body without lifting the urethra from the corpora cavernosa. Any remaining penile chordee was corrected and the urethral plate was transected only when chordee persisted. When the urethral plate was intact and the penis straight, tubularized incised plate urethroplasty was done to correct hypospadias in 1 stage. Otherwise 2-stage repair was performed.


RESULTS
Using this maneuver penile straightening was achieved in 2 of the 9 patients, resulting in a glanular urethral or penoscrotal meatus. Dorsal plication sutures required in 4 cases resulted in a mid shaft and penoscrotal meatus in 1 and 3, respectively. Residual chordee in the remaining 3 patients necessitated division of the urethral plate and 2-stage repair despite aggressive mobilization of the proximal urethra. Simultaneous tubularized incised plate urethroplasty was then performed in the 4 penoscrotal and 1 mid shaft meatus. All 6 patients who underwent a successful 1-stage procedure have excellent cosmetic results, while 1 required meatotomy. No fistula or chordee was present at a mean of 13.8 months of followup (range 3.9 to 27.1).


CONCLUSIONS
This safe, rapid technique may compensate for significant penile tethering and chordee in a subpopulation of patients with proximal hypospadias, such as 6 of the 9 in our study. It also allows successful tubularized incised plate urethroplasty to be done simultaneously.
