Free Tunica Vaginalis Patch in Urethroplasty

Use of a Digestive Mucosal Graft in Urethroplasty

“…Talja et al [6] in 1987 studied the histology of foreskin and tunica vaginalis grafts. They noted that preputial grafts preserved their stratified squamous cell epithelium but the areas plastied with tunica vaginalis tissue were covered with cells resembling normal transitiocellular cells of 3-4 layers.…”

“…Since 1909 a vari ety of graft tissues have been used in urinary tract replace ment; however, most of these grafts have since been aban doned, i.e. ureter [1], sapenous vein [2], umbilical vein [3], artery [4], peritoneum [5] and tunica vaginalis [6], Split thickness skin grafts have also been extensively used [7] with limited results as well as a significant complica tion rate (extensive stenosis, multirecurrent fistula, recur rent chordee). Currently the most accepted alternative solution to the island flap technique [8,9] is either the use of a bladder mucosal graft [10][11][12] or a buccal mucosal graft [13,14],…”

Onlay foreskin flap anastomosed directly to the tunica albuginea: A short-term experimental study in rabbits

“…In order to treat these patients in a single step, various tissues have been studied to replace the urethral plate when it needs to be sectioned. Among these are the peritoneum, bladder mucosa, tunica vaginalis, and buccal mucosa, with outcomes published in clinical and experimental studies over the years [12][13][14][15][17][18][19][20][21][22]. Likewise, urethral healing has been experimentally studied for decades and more intensively over the past 10 years [12][13][14][15][23][24][25][26].…”

Tunica Vaginalis Pedicle Flap for Reconstruction of Anterior Urethral Stricture

“…Historically, in 1967 Ariyoshi reported the first use of tunica vaginalis for urethroplasty in an experimental study. After that, in 1987 Talja et al used it as a ventral onlay graft. In 1988 Khoury et al used tunica vaginalis as a tubularized flap.…”
