Transplantation of a Free Peritoneal Patch in Surgery of the Renal Pelvis and Ureter

Tunica vaginalis Free Grafts for Closure of Urethrocutaneous Fistulas

“…Peritoneal grafts or a peritoneal duplica tion technique have been described for the treatment of Ormond's disease [6]. Free peritoneal grafts were used successfully to envelop the renal pelvis and ureter after reconstructive surgery to prevent adhesions and scarring or even to cover defects of the renal pelvis after resection of a bilateral superficial urothelial tumor of the renal pelvis [7], Free tunica vaginalis grafts have been used as perito neal equivalents by Perlmutter et al [8] for the correc tion of severe chordee in prepubertal boys with hypospa dias. After incision of the tunica albuginea at the point of curvature and straightening of the penis, the tunica va ginalis graft was sutured into the defect.…”

“…In 1986, Snow [13] described the use of pedicled tunica vaginalis for hypospadias repair to prevent post operative fistula formation, thus repopularizing a tech nique mentioned as early as 1970 by Hosli [14], Our good experience with free peritoneal grafts [7] prompted us to use free tunica vaginalis grafts as an adjunct during closure of urethrocutaneous fistulas or difficult hypospa dias repair to reduce the incidence of fistula formation [ 15]. One of the basic tenets of fistula repair, i.e.…”

An Alternative Technique for Treating Complex Ureteral Strictures and Defects using A Peritoneal Graft

“…In urology a pediculated peritoneal graft was initially used for cistoplasty and closure of vesicovaginal fistulae [24] but a free peritoneal graft was used for the first time in animal experiments for bladder repair with good results from Hutschenreiter [25]. Thueroff [26] used a free peritoneal graft to cover defects of the renal pelvis not suitable for primary closure or to envelope renal pelvis and/or ureter to reduce the risk of extrinsec obstruction, due to scarring in 31 patients, with good results in 25.…”

Free Tunica Vaginalis Patch in Urethroplasty

“…In urology pediculated grafts have been success fully used for closing vesicovaginal fistulae [Hohenfellner et al, 1966] as well as for cystoplasty [Hohenfellner, 1965;Jelly, 1970;Tsuji et al, 1963]. Also free peri toneal grafts have been used in renal pelvis and ureter surgery [Hutschenreiter et al, 1978;Thüroff et al, 1981;Lanza et al, 1985] as well as in Peyronie's disease [Das and Maggio, 1979;Das, 1980;Amin et al, 1980;Das and Amar, 1982] with good results. Peritoneum and peritoneum-covered omentum have also been used in the prevention of scarring causing upper urinary tract…”
