Buccal mucosal urethroplasty: a versatile technique for all urethral segments

OBJECTIVE: To present our experience with buccal mucosa urethroplasty for substitution of all segments of the anterior urethra, as the buccal mucosal graft (BMG) has emerged as the tissue of choice for single-stage reconstruction of bulbar urethral strictures, but its use for reconstructing meatal, pendulous and pan-urethral strictures has not been widely reported. PATIENTS AND METHODS: Between January 1998 and October 2003, 92 patients had a BMG substitution urethroplasty at our institution; 75 had a single-stage dorsal onlay BMG urethroplasty (bulbar 41, pendulous 16 and pan-urethral 18; six combined penile skin flap and BMG) and 17 (pendulous five, pan-urethral 10, bulbar two) a two-stage urethroplasty. Recurrence rates, complications and cosmetic outcomes were analysed retrospectively. RESULTS: Over a median (range) follow-up of 34 (8-72) months, 66 (88%) patients with a one-stage reconstruction (14/16 pendulous; 37/41, 90%, bulbar; 15/16 pan-urethral) remained stricture-free. The mean (range) time to recurrence was 9.4 (3-17) months. Of the nine recurrent strictures, six were managed by one-stage optical urethrotomy and three required a repeat urethroplasty. In patients who had a staged procedure, after a mean follow-up of 24.2 (9-56) months, one had complete graft loss, requiring re-grafting, five required stomal revision after stage 1, and only two (12%) developed a recurrent stricture after the two-stage urethroplasty. CONCLUSION: A one-stage dorsal onlay BMG urethroplasty provides excellent results for strictures involving any segment of the anterior urethra. The BMG appears to be the most versatile urethral substitute, as it can be successfully used for both one- and two-stage reconstruction of the entire anterior urethra.     

The penis transposed to the perineum with penile-prostatic anastomotic urethroplasty for the treatment of a long segment complex urethral strictures

BackgroundTo present our experience of transposing the penis to the perineum, with penile-prostatic anastomotic urethroplasty, for the treatment of complex bulbo-membranous urethral strictures.MethodsBetween January 2002 and December 2018, 20 patients with long segment urethral strictures (mean 8.6 cm, range 7.5 to 11 cm) and scarred perineoscrotal skin underwent a procedure of transposition of the penis to the perineum and the penile urethra was anastomosed to the prostatic urethra. Before admission 20 patients had unsuccessful repairs (mean 4.5, range 2 to 12); five patients were associated urethrorectal fistula; 16 patients reported severe penile erectile dysfunction (PED) or no penile erectile at any time and four reported partial erections.ResultsThe mean follow-up period was 45.9 (range 12 to 131) months. Nineteen patients could void normally with a mean Qmax of 22.48 (range 15.6 to 31.4) mL/s. One patient developed postoperative urethral stenosis. After 1 to 10 years of the procedure, nine patients underwent the second procedure. Of the nine patients, four underwent straightening the penis and one-stage anterior urethral reconstruction using a penile circular fasciocutaneous skin flap, and five underwent straightening the penis and staged Johanson urethroplasty. Seven patients could void normally, one developed urethrocutaneous fistula and one developed urethral stenosis.ConclusionsTransposition of the penis to the perineum with pendulous-prostatic anastomotic urethroplasty may be considered as a salvage option for patients with complex long segment posterior urethral strictures.     

One-stage urethral reconstruction for stricture recurrence after urethral stent placement

PURPOSE: We report our 8-year experience with 1-stage open urethral reconstruction in 10 patients with recurrent bulbar and/or membranous strictures after UroLume urethral stent placement. MATERIALS AND METHODS: Ten consecutive referral patients underwent preoperative contrast imaging and urethroscopy followed by primary anastomotic repair or substitution urethroplasty, with concomitant open UroLume removal (when the stent was still present). Postoperative evaluation included contrast imaging 3 weeks after surgery, urethroscopy 4 months after surgery, uroflowmetry, and American Urological Association symptom score assessment. RESULTS: At a medium followup of 51.2 months all patients remain free of bulbar or membranous stricture recurrence. No patient has required dilation or any other intervention. CONCLUSIONS: One-stage open reconstruction with stent extraction offers a definitive treatment option with a high success rate for patients with recurrent bulbar and/or membranous strictures following urethral stent placement.     

Surgical anatomy of the male and female urethra.

The urethra is lined by transitional and stratified columnar epithelium. The urethra can be divided into both anatomic (prostatic, membranous, bulbar, and pendulous) and functional (anterior and posterior) segments. In the male, the anterior urethra is contained within the corpus spongiosum and penis. The urethra in the male and female is located within the urogenital triangle and pierces the superficial and deep perineal spaces of the pelvic floor. The urethra is surrounded by perineal and pelvic musculature that provide support and also form the urethral sphincter mechanism. Cancers of the anterior urethra preferentially drain into superficial inguinal lymph node channels. Those of the posterior urethra (prostatic, membranous, and bulbar segments in the male and the proximal two thirds of the urethra in the female) generally drain into pelvic lymphatic channels. A thorough knowledge of urethral and regional anatomy allows for complete tumor excision, optimal reconstruction, and in selected cases, restoration of urinary tract function.     

Muscle- and nerve-sparing bulbar urethroplasty: a new technique

BACKGROUND: To describe a new surgical technique for the repair of bulbar urethral strictures to preserve the bulbospongiosum muscle and its perineal innervation. OBJECTIVE: Surgical steps of muscle- and nerve-sparing bulbar urethroplasty are described. The outcome is provided regarding semen sequestration and postvoiding dribbling. DESIGN, SETTING, AND PARTICIPANTS: We performed the procedure in 12 patients (average age: 43.58 yr) with bulbar urethral strictures (average stricture length: 4.47cm). SURGICAL PROCEDURE: Six patients underwent urethroplasty using a ventral oral mucosal onlay graft, and six patients underwent urethroplasty using a dorsal oral mucosal onlay graft. In all patients, the surgical approach to the bulbar urethra was made avoiding dissection of the bulbospongiosum muscle from the corpus spongiosum and leaving the central tendon of the perineum intact. MEASUREMENTS: Clinical outcome was considered a failure when any postoperative instrumentation was needed. The primary outcome examined the technical feasibility of the muscle- and nerve-sparing bulbar urethroplasty. The secondary outcome examined the presence or absence of postoperative postvoid dribbling and semen sequestration using a nonvalidated questionnaire (Appendix). RESULTS AND LIMITATIONS: In all patients, postoperative voiding cystourethrography was performed 3 wk after surgery and no urethral sacculation was evident. Urethrography were repeated after 6 mo and 12 mo. No postvoid dribbling or semen sequestration was demonstrated in all patients at 6 mo and 12 mo after surgery. No patient showed stricture recurrence. The average follow-up was 15.25 mo (range 12 mo to 26 mo, median 13.5 mo). CONCLUSIONS: Bulbar urethroplasty preserving the bulbospongiosum muscle, the central tendon of the perineum, and the perineal nerves is a safe, feasible, minimally invasive alternative to traditional bulbar urethroplasty.     

A New Biaxial Epilated Scrotal Flap for Reconstructive Urethral Surgery

Purpose

We describe a new type of perineum based scrotal flap with biaxial vascularization supplied by both superficial perineal arteries. Flap length of up to 20 cm. may be attained for urethral reconstruction.

Materials and Methods

A total of 37 men with complex urethral stenosis of different etiologies underwent surgery using 1 of 3 urethroplasty techniques based on this new flap. The whole anterior urethra, including pendulous and bulbar segments, was reconstructed with a scrotal patch in 10 patients. A scrotal tubular flap was used as a substitute for the bulbar urethra in 7 patients and for the membranous portion in 4. Bulbar urethroplasty with a scrotal island patch was performed in 16 patients.

Results

Of the patients 86% achieved normal voiding after 1-stage urethroplasty. Mean followup was 39.5 months.

Conclusions

The excellent axial vascularization of this new flap permits successful resolution of the most complex urethral stenoses regardless of extension, location and etiology.     

Reconstruction of Membranous Urethral Strictures

Purpose of Review

Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries. We review the literature focusing on the anatomy of membranous urethra and on the evolution of treatments for membranous urethral strictures.

Recent Findings

Non-traumatic strictures affecting bulbomembranous urethra are typically sequelae of instrumentation, transurethral resection of the prostate, prostate cancer treatment, and pelvic irradiation. Being a different entity from trauma-related injuries where urethra is not in continuity, a new understanding of membranous urethral anatomy is necessary for the development of novel reconstruction techniques. Although efficacious and durable to achieve urethral patency, classical bulboprostatic anastomosis carries a risk of de-novo incontinence and impotence. Newer and relatively less invasive reconstructive alternatives include bulbar vessel-sparing intra-sphincteric bulboprostatic anastomosis and buccal mucosa graft augmented membranous urethroplasty techniques. The accumulated experience with these techniques is relatively scarce, but several published series present promising results. These approaches are especially indicated in patients with previous transurethral resection of the prostate in which sparing of rhabdosphincter and the cavernous nerves is important in attempt to preserve continence and potency. Additionally, introduction of buccal mucosa onlay grafts could be especially beneficial in radiation-induced strictures to avoid transection of the sphincter in continent patients, and to preserve the blood supply to the urethra for incontinent patients who will require artificial urinary sphincter placement. The evidence regarding erectile functional outcomes is less solid and this item should be furtherly investigated.

     

Dorsal or ventral placement of the preputial/penile skin onlay flap for anterior urethral strictures:does it make a difference?

OBJECTIVE: To report our experience in managing complex anterior urethral strictures with a dorsally/dorsolaterally placed penile/preputial vascularized flap, and to discuss the advantages of this procedure over a traditional ventrally placed flap. PATIENTS AND METHODS: Between 1995 and 1999, 40 patients (mean age 40.5 years) with recurrent strictures of the pendulous and/or bulbar urethra were treated with longitudinal penile/circumpenile flap substitution urethroplasty. Nineteen patients underwent dorsal placement of the flap as an onlay (DO), whereas 21 patients had a ventral onlay (VO). Five patients needed inferior pubectomy to facilitate high proximal placement of the flap. RESULTS: Both groups had statistically similar ages, number of previous interventions, stricture site, length and follow-up. After a median follow-up of 27.5 months, the stricture recurred in three (24%) of the VO and two (11%) of the DO groups (P > 0.05). One patient in the VO group required surgical closure of the urethral fistula. Flap pseudo-diverticulum and/or sacculation with postvoid dribble occurred in six patients in the VO and none in the DO group (P = 0.01). CONCLUSIONS: Dorsal placement of the pedicled flap is anatomically and functionally more appropriate than the traditional VO placement. DO preputial/penile flap urethroplasty is a versatile procedure and can be applied even for long anterior urethral strictures, including reconstruction of the meatus and high proximal bulbar strictures.     

Penile circular fasciocutaneous flaps to reconstruct complex anterior urethral strictures

The circular fasciocutaneous penile flap meets all criteria for tissue transfer and urethral reconstruction. It reliably provides ample hairless tissue, usually 13 to 15 cm long, without compromising cosmesis or function. We find it ideal for long strictures in the distal or pendulous urethra, where the decreased substance of the corpus spongiosum may jeopardize graft viability. A second major advantage is its versatility: it can be used throughout the entire anterior urethra, from the membranous area to the meatus. In addition, the circular fasciocutaneous penile flap is easily combined with other tissue-transfer techniques when necessary, enabling one-stage reconstruction in the majority of cases. The flap may be tubularized for replacement urethroplasty or divided and used in two separate stenotic areas. Onlay reconstruction is preferable to flap tubularization and has provided a better initial and long-term outcome. The circular fasciocutaneous penile flap provides superior results even in patients with complex refractory strictures in whom previous attempts at anterior urethroplasty have failed. We believe its superiority resides in the transfer of well-vascularized tissue to the compromised area. Complications can be minimized by avoiding prolonged placement in the exaggerated lithotomy position and by meticulous attention to principle of reconstructive surgery.

Treatment of urethral stricture by free full-thickness skin graft (Devine) urethroplasty

Eighteen patients with urethral stricture were treated with Devine urethroplasty and were followed for a period of nine to thirty-six months. There was one failure, and 15 patients had good or excellent results with one operative procedure. A second surgical procedure was performed in two patients with a good end-result. The procedure is applicable to strictures of any length and may be used for strictures in the anterior and bulbous urethra. It may be used also for strictures extending into the membranous urethra.     

Dorsal on-lay preputial graft urethroplasty for anterior urethra strictures repair

Objectives To report the long-term results and evaluate the effectiveness of the dorsal on-lay preputial graft urethroplasty in patients suffering from anterior urethra strictures. Methods A total of 21 male patients, mean age 46.3 years (range 17–67), with anterior urethral strictures, underwent the dorsal on-lay preputial graft urethroplasty during the last 8 years, from October 1997 to September 2005. Strictures were located in bulbar urethra in 16 patients and in penile urethra in the remaining 5. The aetiology the stricture was traumatic injury of the anterior urethra in 12 patients and iatrogenic in 9 patients.␣A direct vision dorsal urethrotomy and the insertion of an urethral Foley catheter right before the procedure, facilitated the corpus spongiosum dissection and the preparation for urethroplasty. A voiding cystogram was performed on the day of urethral catheter removal to exclude extravasation and estimate the postoperative result. Results Mean follow-up time has been 49.9 months (range 6–95) and the outcome was favourable in 15 patients (71.43%). There were 3 recurrences in penile urethra strictures managed conservatively and three in bulbar urethroplasties, treated with internal urethrotomy followed by urethral dilatations. Conclusion Our results indicate that dorsal on-lay urethroplasty using preputial graft is an easy to learn and perform procedure, and offers the patient durable␣results with rather minimal complications.     

Proximal bulbar urethroplasty via extended anastomotic approach--what are the limits?

PURPOSE: We report our initial experience with men who underwent EAU for strictures greater than 2.5 cm involving the proximal bulbar urethra. MATERIALS AND METHODS: Of the more than 250 men who underwent urethral reconstruction at our institution during 1997 to 2005 a select consecutive group of 22 in whom proximal bulbar urethral strictures were treated with primary bulbomembranous anastomosis were evaluated. Outcomes in men with strictures greater than 2.5 cm long (EAU) were compared to those in men with shorter strictures in the same proximal bulbar location. Cases of post-traumatic urethral disruption related to pelvic fractures were omitted. American Urological Association symptom index scores and erectile function questionnaires were completed more than 6 months postoperatively. Results of a prior study using the same erectile function questionnaire after various types of urethroplasty and circumcision were then compared to those of our series. RESULTS: Patients with EAU had an average stricture length of 3.78 cm (range 2.6 to 5.0) and 10 of 11 procedures (91%) were successful. Anastomotic urethroplasty performed for similar proximal bulbar strictures less than 2.5 cm (mean 1.5, range 1.0 to 2.3) was successful in 10 of 11 cases (91%). Mean followup was 22.1 months and all followups were more than 1 year. Men treated with EAU had no increased rate of stricture recurrence or erectile complaints compared to men in whom shorter proximal bulbar strictures were repaired using an identical surgical technique. Similarly no increased rate of erectile problems was identified compared to other types of urethroplasty and circumcision using an identical questionnaire. CONCLUSIONS: Urethral reconstructability is proportional to the length and elasticity of the distal urethral segment. Defects up to 5 cm may be successfully excised and primarily reconstructed in select young men with proximal bulbar strictures.     

Buccal mucosa graft urethroplasty for anterior urethral stricture repair: evaluation of the impact of stricture location and lichen sclerosus on surgical outcome

PURPOSE: We report our experience with buccal mucosa grafts for anterior urethral strictures. We compared outcomes in the pendulous and bulbar urethra as well as the impact of lichen sclerosus on success. MATERIALS AND METHODS: A total of 53 men underwent buccal mucosa graft urethroplasty from 1997 to 2004 for strictures of all etiologies, including lichen sclerosis in 13. Of the patients 46 underwent 1-stage repair and 7 with full-thickness circumferential disease underwent multistage repair. For 1-stage repair strictures were limited to the bulb in 33 cases and they involved the pendulous urethra in 13. A dorsal onlay was used in 24 cases and a ventral onlay was used in 22. For multistage urethroplasty 2 strictures were in the bulbar urethra and 5 were in the pendulous urethra. Success was defined as no postoperative procedures or complications. RESULTS: The success rate of all urethroplasties was 81% (43 of 53 cases) at a mean followup of 52 months. For bulbar vs pendulous urethroplasty the success rate was 86% (30 of 35 cases) vs 72% (13 of 18, p = 0.23). For 1-stage urethroplasty by graft location success was achieved in 20 of 24 cases (83%) for dorsal onlay vs 17 of 22 (77%) for ventral onlay (p = 0.61), in 18 of 21 (86%) for bulbar-dorsal onlay, in 10 of 12 (83%) for bulbar-ventral onlay, in 2 of 3 (66%) for pendulous-dorsal onlay and in 7 of 10 (70%) for pendulous-ventral onlay. For multistage urethroplasty success was achieved in 2 of 2 cases (100%) for bulbar repair vs 4 of 5 (80%) for pendulous repair. In the 13 patients with lichen sclerosus success was achieved in 4 of 8 (50%) with 1-stage repair vs 4 of 5 (80%) with multistage repair (p = 0.28). Complications developed in 10 of 53 cases (19%), including fistula in 1, urinary tract infection in 1 and stricture in 8 that required treatment, including dilation in 3, internal urethrotomy in 4 and perineal urethrostomy in 1. Five of these 8 recurrent strictures (63%) developed in patients with lichen sclerosus, including 4 in urethras in which 1-stage repair was done for lichen sclerosus. There were no donor site complications, postoperative erectile dysfunction or chordee. CONCLUSIONS: A buccal mucosa graft placed dorsally or ventrally remains an excellent graft material in the bulbar and pendulous urethra. When lichen sclerosus is present, careful consideration should be given to complete excision of the diseased urethra with multistage repair vs accepting a higher rate of stricture recurrence with 1-stage repair.     

Reconstructive Management with Buccal Urethroplasty

We present the historical evolution of the use of buccal mucosa in reconstructive surgery, from the first application in ophthalmology to paediatric surgery and, finally, urethral surgery. This process spanned 99 yr, from 1894 to 1993. The harvesting of buccal mucosa from the cheek requires careful preoperative patient evaluation and selection. To avoid postoperative complications related to the harvesting site, we provide some suggestions based on a large series of patients. The use of a one- or two-stage repair procedure in penile urethroplasty is discussed, and some step-by-step surgical techniques are suggested. The reconstruction of the bulbar urethra using buccal mucosa in traumatic and nontraumatic strictures is also discussed, and different techniques are presented. Finally, appraisal and discussion of some challenging topics (eg, evidence for efficacy, complications, implications, worldwide use) concerning the use of buccal mucosa for urethral stricture reconstruction are presented based on the current literature.Patient summaryWe looked at the history and evolution of the use of buccal mucosa for reconstructive urethral surgery and found that harvesting the buccal mucosa from the cheek is a safe procedure. The use of buccal urethroplasty represents the gold standard in the management of patients with anterior urethral strictures.     

Die bulbäre Harnröhrenstriktur

Urethral strictures are often located in the bulbar urethra, and bulbar strictures are commonly due to urethral trauma. Diagnosis is confirmed by radiographic imaging of the urethra. In cases of short primary bulbar strictures, a simple internal urethrotomy may be curative. In contrast, open surgery should be performed in long segment or recurrent strictures because recurrence rates are near 100% in these cases. Depending of the actual findings and comorbidities, end-to-end anastomosis, graft urethroplasty, flap urethroplasty, or perineal urethrostomy may be used. If definitive treatment using open surgery is delayed and multiple endoscopic treatments are tried, urethroplasty becomes more complex and success rates of definitive treatment decline.     

Transperineal end-to-end anastomotic urethroplasty for traumatic posterior urethral disruption and strictures in children

OBJECTIVE: To report the long-term results of transperineal end-to-end anastomotic urethroplasty for post-traumatic posterior urethral stenosis in children. METHODS: From 1975 to 1996, 25 boys [aged 3 to 12 years] with post-traumatic posterior urethral stenosis or obliteration, and one boy [aged 7 years] with disrupted posterior urethra were treated with transperineal end-to-end anastomotic urethroplasty. Final follow-up assessments including voiding status, urinary continence and erectile function were performed in June 1999. RESULTS: Smooth voiding was restored in 25 boys postoperatively. one child failed an ill-prepared repair and was waiting for further intervention. Among the 25 patients, seven were lost to the final follow-up. All seven boys had a single urethroplasty for simple urethral stenosis and had been followed for 3 to 5 years postoperatively with smooth voiding. The other 18 boys, including seven with complex urethral stenosis [three with a history of failed previous urethroplasties, three with urethrorectal fistula and one with urethroperineal fistula], underwent a total of 22 end-to-end anastomotic urethroplasties [one successful primary repair, 17 successful delayed repairs and four failed repairs]. Of the 17 patients with successful delayed repair, 14 succeeded with one repair, two with two repairs and one with three repairs. The success rate per repair for simple urethral strictures was 94.7% [18 of 19], and for complex strictures 63.6% [7 of 11]. Stress incontinence was found in three cases, impotence in two. Concomitant impotence and stress incontinence were found in one of the five patients.CONCLUSION: Transperineal end-to-end anastomotic urethroplasty can achieve good long-term outcomes in children with simple post-traumatic posterior urethral stenosis. In experienced hands, good results can also be achieved for complex urethral strictures.     

Adult anterior urethral strictures: a national practice patterns survey of board certified urologists in the United States

PURPOSE: We determined the methods and patterns of the evaluation of and treatment for adult anterior urethral stricture disease by practicing urologists in the United States. MATERIALS AND METHODS: A nationwide survey of practicing members of the American Urological Association was performed by a mailed questionnaire. A total of 1,262 urologists were randomly selected from all 50 states, of whom 431 (34%) completed the questionnaire. RESULTS: Most urologists (63%) treat 6 to 20 urethral strictures yearly. The most common procedures used by those surveyed for urethral strictures were dilation (92.8%), optical internal urethrotomy (85.6%) and endourethral stent (23.4%). Minimally invasive procedures are used more frequently that any open urethroplasty technique. Furthermore, most urologists (57.8%) do not perform urethroplasty surgery. When used, the most common urethroplasty surgeries performed were end-to-end anastomotic urethroplasty, perineal urethrostomy and ventral skin graft urethroplasty. Few urologists (4.2%) performed buccal mucosa grafts. For a long bulbar urethral stricture or short bulbar urethral stricture refractory to internal urethrotomy 20% to 29% of respondents would refer to another urologist, while 31% to 33% would continue to manage the stricture by minimally invasive means despite predictable failure. Of the urologists 74% believed that the literature supports a reconstructive surgical ladder, in which urethroplasty is only performed after repeat failure of endoscopic methods. CONCLUSIONS: Most urologists in the United States have little experience with urethroplasty surgery. Most urologists erroneously believe that the literature supports a reconstructive surgical ladder for urethral stricture management. Unfamiliarity with the literature and inexperience with urethroplasty surgery have made the use of endoscopic methods inappropriately common.
