1.Urethroplasty technological changes for the treatment of male urethral stricture.
Chinese Journal of Surgery 2022;60(11):981-986
Urethroplasty is an important method to treat male urethral stricture. Nowadays, urethroplasty mainly includes two types: anastomotic urethroplasty and substitution urethroplasty. Anastomotic urethroplasty mainly includes primary anastomosis urethroplasty and non-transecting anastomotic urethroplasty. Substitution of urethroplasty mainly includes staged urethroplasty and one-stage urethroplasty. Substitution materials always are chosen by pedicle skin flap and free mucosal graft. Anastomosis urethroplasty has shown good results in short bulbar urethral stricture and posterior urethral stricture after pelvic fracture. Among them, non-transecting anastomosis urethroplasty has become a new surgical method for iatrogenic, single, short or non-occluded stenosis. At present, the one-stage substitution urethroplasty is the most widely used. However, there are still many complicated cases that must be solved by staged urethroplasty. Pedicle skin flap and oral mucosa are widely used as substitutes at present. How to select the best surgical procedure and substitute materials individually would be the problem worthy of attention in the future. Accumulating more long-term follow-up data is helpful for objective comparison of various surgical procedures and grafts.

Penile urethral strictures have been managed by a staged surgical approach. In selected cases, spongiofibrosis can be excised, a neo-urethral plate created using buccal mucosa graft (BMG) and tubularized during the same procedure, performing a "two-in-one" stage approach. We aim to identify stricture factors which indicate suitability for this two-in-one stage approach. We assess surgical outcome and compare with staged reconstruction. We conducted an observational descriptive study. The data were prospectively collected from two-in-one stage and staged penile urethroplasties using BMG in a single center between 2007 and 2017. The minimum follow-up was 6 months. Outcomes were assessed clinically, radiologically, and by flow-rate analysis. Failure was defined as recurrent stricture or any subsequent surgical or endoscopic intervention. Descriptive analysis of stricture characteristics and statistical comparison was made between groups. Of 425 penile urethroplasties, 139 met the inclusion criteria: 59 two-in-one stage and 80 staged. The mean stricture length was 2.8 cm (single stage) and 4.5 cm (staged). Etiology was lichen sclerosus (LS) 52.5% (single stage) and 73.8% hypospadias related (staged). 40.7% of patients had previous failed urethroplasties in the single-stage group and 81.2% in the staged. The most common stricture locations were navicular fossa (39.0%) and distal penile urethra (59.3%) in the single-stage group and mid or proximal penile urethra (58.7%) in the staged group. Success rates were 89.8% (single stage) and 81.3% (staged). A trend toward a single-stage approach for select penile urethral strictures was noted. We conclude that a single-stage substitution penile urethroplasty using BMG as a "two-in-one" approach is associated with excellent functional outcomes. The most suitable strictures for this approach are distal, primary, and LS-related strictures.

Tubularized graft urethroplasty fails largely because of inadequate graft take. Prefabrication of buccal mucosa lined flap has theoretical indications for constructing neourethra with an independent blood supply. The efficacy of using a tissue expander capsule as an induced vascular bed to prefabricate an axial vascularized buccal mucosa-lined flap for tubularized urethral reconstruction in a rabbit model was tested. The experiments were performed in three stages. First, silicone tissue expanders were inserted into the groin to induce vascularized capsule pouch formation. Next, buccal mucosa grafts were transplanted to the newly formed capsular tissue supplied by the axial vessel for buccal mucosa-lined flap prefabrication. Then, circumferential urethral defects were created and repaired by buccal mucosa graft (Group 1), capsule flap (Group 2) and prefabricated capsule buccal mucosa composite flap (Group 3). With retrograde urethrography, no rabbits in Group 1 maintained a wide urethral caliber. In Group 2, the discontinued epithelial layer regenerated at 1 month, and the constructed neourethra narrowed even though the lumen surface formed intact urothelial cells at 3 months. In Group 3, buccal mucosa formed the lining in the neourethra and kept a wide urethral caliber for 3 months. The capsule may serve as an induced vascular bed for buccal mucosa-lined flap prefabrication. The prefabricated buccal mucosa-lined flap may serve as a neourethra flap for circumferential urethral replacement.

BACKGROUND: As harvesting techniques have improved the viability of transposed adipose tissue, autologous fat transfer is increasingly utilized for facial augmentation. Conventional techniques involve placing harvested fat deep in subcutaneous tissue through skin punctures. Trans-oral fat injections at the buccal and labial sulci and through the mucosa of the oral commissures obviate external scars. We report experience with this technique for augmentation of the cheeks, zygomatic arch, nasolabial folds, upper and lower lips, and chin in 130 patients over a 14-year period. METHODS: We report an observational case series of 147 procedures performed in 130 patients (118 women and 12 men, 19-69 years of age) in which 10 to 60 mL autologous fat supernatant harvested from the hips, buttocks, or abdomen were injected through the oral mucosa for augmentation. Single preoperative doses of antibiotic and methylprednisolone were administered in all cases. Fat frozen and banked during initial treatments was used for additional augmentation 3 to 6 months after initial treatments in 46% of cases. Outcomes were assessed clinically with physical exams and photographs. RESULTS: Mucosal puncture wounds healed uneventfully. Most patients tolerated the procedures well and recovered rapidly compared to historical experience with conventional percutaneous techniques. One patient developed a sterile seroma 3 weeks after facial augmentation that responded to needle aspiration. CONCLUSIONS: Transmucosal, intra-oral autologous fat grafting was associated with minimal visible scarring, swelling, or infection at the recipient site. This technique may be considered an alternative to percutaneous transfer for proximate peri-oral facial augmentation.

OBJECTIVETo investigate the reconstruction of 1/4 defect on upper-lip vermilion with a lower-lip vermilion compound tissue flap pedicled at oral commissure.
METHORDSAt the first stage, the lower lip mucosal flap pedicled by inferior labial artery was transposed to reconstruct the defect on upper lip vermilion and tubercle. The defect at the donor site was closed directly. At the second stage, the flap pedicle was cut off and revised.
RESULTS6 patients were treated with satisfactory aesthetic results. All the flaps survived completely. The oral commissure kept normal with no obvious scar at the donor sites.
CONCLUSIONSThe modified crosslip vermilion flap pedicled at oral commissure has the advantages of avoiding inconvenience in feeding, speaking and cleaning. The procedure is simple with available blood supply. Both aesthetic and functional results are satisfactory.

OBJECTIVETo introduce and evaluate the technical feasibility and anatomical and functional outcomes of one-stage vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis.
METHODSWe retrospectively reviewed our experiences with 17 patients with Mayer- Rokitansky-Kuster-Hauser syndrome treated with primary surgery from September 2010 to April 2013. All patients underwent vaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis. We describe the details of this technique, observe the time of epithelization and evaluate the long- term anatomical, functional, and sexual outcomes.
RESULTSThe time of epithelization was 13 d (range: 12-15 d). At a mean follow-up of 15 months (range: 12-24 months), the mean postoperative dependence on the vaginal stent was 11.7 ± 1.64 months (range: 9-15 months), the mean depth of the neovagina was (9.0 ± 0.94) cm (range: 7-11 cm), the mean circumference was (12.3 ± 1.36) cm (range: 10.0-14.5 cm) and the mean volume was (105 ± 10) ml (range 85-120 ml). The mean female sexual function index score of the 12 sexually active patients was 29.5 ± 2.6. No spouse reported discomfort during intercourse.
CONCLUSIONSVaginoplasty with autologous buccal micromucosa combined with acellular allogenic dermis is an effective and feasible approach for patients with Mayer-Rokitansky-Kuster-Hauser syndrome. The procedure has satisfactory long-term anatomical and functional results. The use of the acellular allogenic dermis is limited by the high price and the potential infection.

Tissue transfer techniques are an essential part of the reconstructive urologist's armamentarium. Flaps and graft techniques are widely used in genital and urethral reconstruction. A graft is tissue that is moved from a donor site to a recipient site without its native blood supply. The main types of grafts used in urology are full thickness grafts, split thickness skin grafts and buccal mucosa grafts. Flaps are transferred from the donor site to the recipient site on a pedicle containing its native blood supply. Flaps can be classified based on blood supply, elevation methods or the method of transfer. The most used flaps in urology include penile, preputial, and scrotal skin. We review the various techniques used in reconstructive urology and the outcomes of these techniques.

To describe the novel technique of ventral inlay substitution urethroplasty for the management of male anterior urethral stricture disease. A 58-year-old gentleman with multifocal bulbar stricture disease measuring 7 cm in length was treated using a ventral inlay substitution urethroplasty. A dorsal urethrotomy was created, and the ventral urethral plated was incised. The edges of the urethral plate were mobilized without violation of the ventral corpus spongiosum. A buccal mucosa graft was harvested and affixed as a ventral inlay to augment the caliber of the urethra. The dorsal urethrotomy was closed over a foley catheter. No intraoperative or postoperative complications occurred. Postoperative imaging demonstrated a widely patent urethra. After three years of follow-up, the patient continues to do well with no voiding complaints and low postvoid residuals. Ventral inlay substitution urethroplasty appears to be a safe and feasible technique for the management of bulbar urethral strictures.

10.Reconstruction of an Amputated Glans Penis With a Buccal Mucosal Graft: Case Report of a Novel Technique.
Korean Journal of Urology 2014;55(12):841-843
Penile amputation is a rare catastrophe and a serious complication of circumcision. Reconstruction of the glans penis may be indicated following amputation. Our report discusses a novel technique for reconfiguration of an amputated glans penis 1 year after a complicated circumcision. A 2-year-old male infant presented to us with glans penis amputation that had occurred during circumcision 1 year previously. The parents complained of severe meatal stenosis with disfigurement of the penis. Penis length was 3 cm. Complete penile degloving was performed. The distal part of the remaining penis was prepared by removing fibrous tissue. A buccal mucosal graft was applied to the distal part of the penis associated with meatotomy. The use of a buccal mucosal graft is a successful and simple procedure with acceptable cosmetic and functional results for late reconfiguration of the glans penis after amputation when penile size is suitable.
