abstract
After a longitudinal incision on ventral surface of penis and scrotum, corpus spongiosum and corpus cavernosus exposed.Corpus spongiosum then separated from the bed, by sharp dissection and elevated.Strictured portion of the urethra was identified, urethra turned so that to expose dorsal surface of ...
urethra and fibrous tissue around it excised. Now corpus spongiosum and urethra opened dorsally or dorsolaterally, so that the lumen of urethra facing ventral surface of tunica albuginea of corpus cavernosa. Then silicon catheter was introduced through the meatus and passed beyond the stricture to the bladder.Now cut open tunica albuginea of corpus spongiosum and urethral margins stitched over catheter to tunica albuginea of corpus cavernosa at 5 and 7’O clock position incorporating the above mentioned groove.Thus roof formed by ventral surface of tunica albuginea of corpus cavernosa and floor formed by the urethral segment and dorsal surface of the tunica albuginea of corpus spongiosum.
reason, objective, purpose
In tunica albuginea urethroplasty ventral aspect of tunica albuginea of corpora cavernosa is utilized to form the roof of neourethra. No flap or graft is harvested or applied, as tunica albuginea is itself sufficient to maintain lumen and allow regrowth urothelium over it. Putting graft or flap may not add any further advantage over tunica, rather invites more inflammation at reconstruction site. The greatest advantages of using tunica albuginea is a locally available and structurally similar, so that there is no need to use anatomically and structurally dissimilar distant tissues like buccal mucosa, prepuceal skin, vein fascia lata, tunica vaginalis, arterial homograft, buccal or bladder mucosa piece of intestine or Teflon graft
