Additional material is presented with a representative video of this surgery.</p><p id="par0180" class="elsevierStylePara elsevierViewall">The patient is placed in lithotomy position. The suprapubic, scrotal, and perineal regions are shaved and disinfected with chlorhexidine. Ureteroscopy is performed by placing a guidance sensor and a 4-Ch ureteral catheter which surpasses the stricture and gains access to the bladder. Immediately thereafter, with the patient in the dorsal lithotomy position, a perineal–scrotal incision is made on the middle line. The dissection of subcutaneous cell tissue and the incision of Colles’ and Gallaudet's fascia allow for the exposure of the bulbospongiosus muscles. Due to the proximal nature of strictures, it is necessary to section the central tendon of the perineum. The bulbospongiosus muscles are cut on the middle line in a cranio-caudal direction and are laterally separated to expose the corpus spongiosum in its full extent. The corpus spongiosum is subsequently released from dorsal attachments to the albuginea of the corpora cavernosa.</p><p id="par0185" class="elsevierStylePara elsevierViewall">Simultaneously, another surgical team proceeds to obtain the buccal mucosa graft (<a class="elsevierStyleCrossRef" href="#fig0015">Fig. 3</a>). Demarcation of both Stenon's canal and the selected area is done to get the graft. A saline solution with diluted adrenaline is injected on the edges of the marked area, thus performing hydrodissection of the mucosa, to subsequently section the demarcated area using a cold scalpel. Two traction points on the proximal edge of the graft area make their subsequent dissection easier. Once the graft has been removed, the hemostasis is carefully examined and the edges are approximated with reabsorbable 4-0 suture. The graft is made thinner with some scissors and permanent manual contact. Its extraction is simplified by the administration of topical adrenaline. Identifying the parotid canal is particularly important at the moment of extraction.</p><elsevierMultimedia ident="fig0015"></elsevierMultimedia><p id="par0190" class="elsevierStylePara elsevierViewall">The distal edge of the stricture is marked with the help of a Beniqué sound and a dermographic marker. 3 traction points are applied on the urethral spongiosum at different levels. These points keep a precise 180° rotation to make exposure and a comfortable approach to the urethra on its dorsal side easier. A longitudinal incision is made on the dorsal surface of the spongiosum until reaching the cranial limit of the stenotic area (<a class="elsevierStyleCrossRef" href="#fig0020">Fig. 4</a>), with an excellent opening of the urethra being observed and sometimes even the <span class="elsevierStyleItalic">veru montanum</span>.</p><elsevierMultimedia ident="fig0020"></elsevierMultimedia><p id="par0195" class="elsevierStylePara elsevierViewall">This incision enables the visualization of the Beniqué sound and a complete exposure of the urethral lumen through all the stenosed segment. It is advisable to cut 1 more cm, both at the proximal and dorsal levels of the stricture. The affected urethral segment shows a certain degree of fibrosis on the outside, which is removed with scissors, lightening the urethral lumen before proceeding to graft placement. Alternatively, the urethral incision can be made on the ventral side, which implies an easier exposure, though urethral release is equally required. Dorsal positioning implies less graft mobility, which is attached to the base of the crura of the corpora cavernosa and to the trapezoidal space.</p><p id="par0200" class="elsevierStylePara elsevierViewall">The length of the stenotic area is determined with a tape measure and a Foley probe which will serve as a tutor is placed. The proximal part of the graft, which has been previously carved at the bank with reabsorbable 4-0 suture, is fixed. Anastomosis is subsequently completed between the graft and both edges of the urethral lumen in a distal direction, using interrupted stitches of the same suture (<a class="elsevierStyleCrossRef" href="#fig0025">Fig. 5</a>). Two parallel lines of reabsorbable suture stitches applied on the cavernous albuginea and the graft on both sides offer stability to it (<a class="elsevierStyleCrossRef" href="#fig0025">Fig. 5</a>). Once they have been tied in a distal direction without any tension, the urethral spongiosum is once again fixed to the albuginea of the corpora cavernosa.</p><elsevierMultimedia ident="fig0025"></elsevierMultimedia><p id="par0205" class="elsevierStylePara elsevierViewall">The re-approximation of the bulbospongiosus muscles is performed with a 3-0 reabsorbable braided multifilament suture.

However, for strictures greater than 2<span class="elsevierStyleHsp" style=""></span>cm, when the urethral lumen is well preserved and the area of spongiofibrosis is small, augmentation urethroplasty with grafting in the dorsal or ventral position is the ideal technique, with long-term success rates up to 90%.<a class="elsevierStyleCrossRefs" href="#bib0070"><span class="elsevierStyleSup">14–16</span></a></p><p id="par0245" class="elsevierStylePara elsevierViewall">We can use grafts or flaps for augmentation techniques. There is a historical controversy on which of the 2 is the most appropriate one, though nowadays it is clearly established that the recurrence rate of stenosis is 14–15.7%, with no apparent differences between grafts and flaps.<a class="elsevierStyleCrossRef" href="#bib0085"><span class="elsevierStyleSup">17</span></a> However, the complication rate is higher in the donor area when flaps are used. These complications include penile hematoma, skin necrosis, fistula formation, and a higher risk of urethral diverticulum formation.<a class="elsevierStyleCrossRef" href="#bib0090"><span class="elsevierStyleSup">18</span></a></p><p id="par0250" class="elsevierStylePara elsevierViewall">Regarding graft origin, there is currently an increasing trend to use oral mucosa as donor tissue, although historically the preferred tissue has been preputial mucosa or penile skin due to their easier extraction and their histological characteristics. With regard to the use of preputial skin or oral mucosal grafts, the literature shows mixed results. Whereas Alkisafi et al.<a class="elsevierStyleCrossRef" href="#bib0095"><span class="elsevierStyleSup">19</span></a> found no differences among them, Barbagli et al. detected a higher failure rate with preputial mucosa.<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">14</span></a> Our experience is favorable to the use of oral mucosa in all cases. Oral mucosal grafts are resistant and easy to obtain and to handle. They have a thick epithelium with their own thin layer and a dense panlaminar vascular plexus. It is a moist tissue resistant to skin conditions, such as lichen sclerosus. Oral mucosa also has a privileged immunology, having shown in preclinical studies a large number of fibroblasts which reduce fibrosis. In those patients who require the extraction of several free grafts, labial and/or lingual mucosa can also be used, though these tissues are thinner than buccal mucosa.</p><p id="par0255" class="elsevierStylePara elsevierViewall">The development of urethroplasty with oral mucosal grafts in the dorsal position implies an evolution of the techniques used for the treatment of urethral stenosis. In 1979, Devine et al. made the use of genital and extragenital grafts popular for urethral reconstruction.<a class="elsevierStyleCrossRef" href="#bib0100"><span class="elsevierStyleSup">20</span></a> Monseur described in 1980 a new technique where the dorsal surface of the urethra was opened and fixed to the underlying corpora cavernosa, leaving the urethral catheter in place for a long period of time until the regeneration of the oral mucosa.<a class="elsevierStyleCrossRef" href="#bib0105"><span class="elsevierStyleSup">21</span></a> In 1996 Barbagli et al. combined both concepts, thus developing a new treatment paradigm for urethral stenosis based on the placement of a free oral mucosal graft on the dorsal side of the urethra, either with augmented anastomosis or with dorsal onlay grafting without urethral sectioning.<a class="elsevierStyleCrossRef" href="#bib0110"><span class="elsevierStyleSup">22</span></a> The latter technique has become the most commonly used one due to its good, long-lasting results,<a class="elsevierStyleCrossRef" href="#bib0070"><span class="elsevierStyleSup">14</span></a> and it has inspired the experience we present. Most recently, Barbagli et al. have also shown their wide experience with the use of ventral onlay grafting in long strictures of the proximal urethra with a non-traumatic etiology,<a class="elsevierStyleCrossRef" href="#bib0115"><span class="elsevierStyleSup">23</span></a> quite similar to the cases presented here where the graft was ventrally placed.</p><p id="par0260" class="elsevierStylePara elsevierViewall">In short, dorsal urethroplasty with free buccal mucosa graft is a technique which achieves satisfactory results in the repair of long complex strictures of the bulbar urethra with involvement of the membranous urethra. It is a substitute alternative to transperineal bulboprostatic anastomotic repair, traditionally recommended in those cases secondary to urethral trauma which show extensive fibrosis. The aim of the non-anastomotic technique we describe is to enlarge the urethral lumen without causing any shortening. Its results are satisfactory, particularly in patients with limited fibrosis, but with urethral lumen retraction due to thermal injuries, which are possibly secondary to a pervious transurethral resection with poor isolation quality. The probability of success is very high and the number of complications is limited. Patients also benefit from early discharge from hospital.</p></span><span id="sec0070" class="elsevierStyleSection elsevierViewall"><span class="elsevierStyleSectionTitle" id="sect0090">Conflict of interest</span><p id="par0265" class="elsevierStylePara elsevierViewall">The authors declare that they have no conflict of interest.</p></span></span>" "textoCompletoSecciones" => array:1 [ "secciones" => array:11 [ 0 => array:2 [ "identificador" => "xres372194" "titulo" => array:5 [ 0 => "Abstract" 1 => "Introduction" 2 => "Materials and methods" 3 => "Results" 4 => "Conclusion" ] ] 1 => array:2 [ "identificador" => "xpalclavsec351314" "titulo" => "Keywords" ] 2 => array:2 [ "identificador" => "xres372193" "titulo" => array:5 [ 0 => "Resumen" 1 => "Introducción" 2 => "Material y métodos" 3 => "Resultados" 4 => "Conclusión" ] ] 3 => array:2 [ "identificador" => "xpalclavsec351315" "titulo" => "Palabras clave" ] 4 => array:2 [ "identificador" => "sec0045" "titulo" => "Introduction" ] 5 => array:3 [ "identificador" => "sec0050" "titulo" => "Materials and methods" "secciones" => array:1 [ 0 => array:2 [ "identificador" => "sec0055" "titulo" => "Surgical technique" ] ] ] 6 => array:2 [ "identificador" => "sec0060" "titulo" => "Results" ] 7 => array:2 [ "identificador" => "sec0065" "titulo" => "Discussion" ] 8 => array:2 [ "identificador" => "sec0070" "titulo" => "Conflict of interest" ] 9 => array:2 [ "identificador" => "xack94285" "titulo" => "Acknowledgements" ] 10 => array:1 [ "titulo" => "References" ] ] ] "pdfFichero" => "main.pdf" "tienePdf" => true "fechaRecibido" => "2014-03-25" "fechaAceptado" => "2014-04-08" "PalabrasClave" => array:2 [ "en" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Keywords" "identificador" => "xpalclavsec351314" "palabras" => array:6 [ 0 => "Urethroplasty" 1 => "Urethral stricture" 2 => "Bulbar urethra" 3 => "Membranous urethra" 4 => "Oral mucosa graft" 5 => "Reconstructive surgery" ] ] ] "es" => array:1 [ 0 => array:4 [ "clase" => "keyword" "titulo" => "Palabras clave" "identificador" => "xpalclavsec351315" "palabras" => array:6 [ 0 => "Uretroplastia" 1 => "Estenosis uretral" 2 => "Uretra bulbar" 3 => "Uretra membranosa" 4 => "Injerto de mucosa oral" 5 => "Cirugía reconstructiva" ] ] ] ] "tieneResumen" => true "resumen" => array:2 [ "en" => array:2 [ "titulo" => "Abstract" "resumen" => "<span class="elsevierStyleSectionTitle" id="sect0010">Introduction</span><p id="spar0025" class="elsevierStyleSimplePara elsevierViewall">Urethroplasty with oral mucosa grafting is the most popular technique for treating nontraumatic bulbar urethral strictures; however, cases involving the membranous portion are usually treated using progressive perineal anastomotic urethroplasty.
