Lotus Petal Flap Urethroplasty
The lotus petal flap harvests bilateral pedicled fasciocutaneous flaps from the gluteal fold (perineal crease) based on perforators of the internal pudendal artery, in a petal-like configuration that provides vascularized tissue for perineal and panurethral reconstruction. Originally described by Yii and Niranjan in 1996 for vulvoperineal reconstruction, its application to male perineal urethral reconstruction provides reliable coverage of complex defects. The bilateral design allows large-volume tissue transfer with primary donor-site closure.
For the foundations-level deep dive on lotus petal flap anatomy, design variants (Warrier-thinned, Bodin supra-fascial, tunneled, IPAT), evidence base, and indications across vulvoperineal, ELAPE, scrotal, and male-perineal reconstruction, see Lotus Petal Flap (foundations).
