Multi-Institutional Outcomes of Minimally Invasive Harvest of Rectal Mucosa Graft for Anterior Urethral Reconstruction.<\/a><\/p>\n\n\n\n Granieri MA<\/a>1<\/sup>, Zhao LC<\/a>1<\/sup>, Breyer BN<\/a>2<\/sup>, Voelzke BB<\/a>3<\/sup>, Baradaran N<\/a>2<\/sup>, Grucela AL<\/a>4<\/sup>, Marcello P<\/a>5<\/sup>, Vanni AJ<\/a>6<\/sup>.<\/p>\n\n\n\n Author information: Abstract<\/p>\n\n\n\n PURPOSE: <\/p>\n\n\n\n We report multi-institutional outcomes in patients who underwent urethroplasty with a rectal mucosa graft.<\/p>\n\n\n\n MATERIALS AND METHODS: <\/p>\n\n\n\n We used the TURNS (Trauma and Urologic Reconstructive Network of Surgeons) database to identify patients who underwent urethral reconstruction with transanal harvest of a rectal mucosa graft. We reviewed preoperative demographics, stricture etiology, previous management and patient outcomes.<\/p>\n\n\n\n RESULTS: <\/p>\n\n\n\n We identified 13 patients from April 2013 to June 2017. Median age at surgery was 54 years. The stricture etiology was lichen sclerosus in 6 of 13 patients (46%), idiopathic in 2 (15%), hypospadias in 1 (7%), prior gender confirming surgery in 3 (23%) and rectourethral fistula after radiation for prostate cancer in 1 (7%). Prior procedures included failed urethroplasty with a buccal mucosa graft in 9 of 13 patients (69%), direct vision internal urethrotomy in 2 (15 %) and none in 2 (15%). Median stricture length was 13 cm. Stricture location in the 9 cisgender patients was panurethral in 5 (56%), bulbopendulous in 2 (22%) and bulbar in 2 (22%). It was located at the junction of the fixed urethra extending into the neophallus in all 3 patients (100%) who underwent prior gender confirming surgery. Mean rectal mucosa graft length for urethroplasty was 10.6 cm (range 3 to 16). Repair types included dorsal or ventral onlay, or 2-stage repair. Stricture recurred at a median followup of 13.5 months in 2 of 13 patients ( 15%). Postoperative complications included glans dehiscence, urethrocutaneous fistula and compartment syndrome in 1 patient each (7%). No rectal or bowel related complications were reported.<\/p>\n\n\n\n CONCLUSIONS: <\/p>\n\n\n\n Urethral reconstruction with a transanal harvested rectal mucosa graft is a safe technique when a buccal mucosa graft is unavailable or not indicated.<\/p>\n","protected":false},"excerpt":{"rendered":" J Urol. 2019 Jan 29:101097JU0000000000000087. doi: 10.1097\/JU.0000000000000087.
