Urethroplasty For Bulbar Urethral Stricture Research Articles

Grafts are Unnecessary for Proximal Bulbar Reconstruction

We compared our experience with the reconstruction of proximal vs distal bulbar stricture to assess the role of excision and primary anastomosis vs graft procedures at each site. We reviewed all urethroplasties done by a single surgeon during a 2-year period. Data analyzed included patient history and demographics, operative details, stricture length and site, and clinical outcome. The proximal bulbar urethra was defined as the segment within 5 cm of the membranous urethra and the distal bulb was defined as the adjoining segment extending to the penoscrotal junction. Cases involving the pendulous or posterior urethra were excluded from study. Of 210 urethroplasties from 2007 to 2009, 112 were done for bulbar strictures, including 72 (64%) for proximal bulbar strictures. All 72 cases were treated with excision and primary anastomosis. Median stricture length was 2 cm (range 1 to 5), although 31 of 72 strictures (43%) were of intermediate length (2.5 to 5 cm). Recurrence developed in 1 case (1.4%). Distal bulbar strictures in 40 of the 112 cases (36%) were treated predominantly with substitution urethroplasty in 36 (90%), and with excision and primary anastomosis in 4 (10%). Median stricture length was 3.75 cm (range 1.5 to 20). We noted intermediate length stricture in 18 of 40 cases (45%) and recurrence in 11 (28%). Of intermediate length strictures recurrence was much rarer after excision and primary anastomosis than after graft procedures (1 of 33 or 3.0% vs 6 of 16 or 38%, p<0.05). Location is critical when selecting an appropriate technique for bulbar urethral reconstruction. Excision and primary anastomosis are superior to grafts in the proximal bulb. Grafts are often unnecessary for reconstructing proximal bulbar strictures 5 cm or less.

Urethral Reconstruction in Patients With Neurogenic Bladder Dysfunction

There is limited literature examining urethral reconstruction in patients with neurogenic bladder dysfunction. We describe our experience of urethral reconstruction in men with concurrent neurogenic bladder. A prospectively maintained database of all urethral reconstruction procedures performed by 1 surgeon was analyzed for patients with neurogenic bladder dysfunction. Patient characteristics including the etiology of neurogenic bladder, urethral pathology, urethral reconstructive technique, complications and recurrences were evaluated. A total of 23 patients were included in the analysis. Urethral pathology included erosions (10), strictures (7), diverticula (3), urethrocutaneous fistulas (2), and a combination of diverticular and stricture disease (1). Median length of the urethral pathology was 5.0 cm (range 2.0 to 10.0). Overall urethral reconstruction was successful in 16 of 23 patients (69.6%) at a mean followup of 24.7 months (range 2 to 79). Success rates differed among the types of pathology with 60% for urethral erosions, 85.7% for urethral strictures, and 66.6% for urethral diverticula and fistulas. Of those cases of recurrence 4 of 7 (57%) were after urethral erosion repair. There was 1 (4.3%) postoperative complication and no patient underwent urinary diversion after recurrence. When identified at an early stage, urethral reconstruction in patients with neurogenic bladder dysfunction offers acceptable outcomes with limited morbidity. Men undergoing reconstruction for urethral erosion had inferior outcomes compared to those with other urethral pathology.

V-07.08: Dorsal buccal mucosa onlay graft bulbar urethroplasty by means of fibrin glue

Buccal mucosa tissue has been widely used in complex bulbar urethral stricture using ventral or dorsal urethral opening with comparable long-term outcomes. We present a new surgical technique of dorsal onlay graft urethroplasty for bulbar urethral strictures: fibrin glue is used in order to fix the buccal mucosal graft to the corpora cavernosa thus facilitating the apposition and adhesion of the graft to the receiving bed.

The Tongue as an Alternative Donor Site for Graft Urethroplasty: A Pilot Study

Urethroplasty with a buccal mucosal graft provides excellent clinical results but it may also cause oral complications in some cases. The mucosa covering the lateral and under surface of the tongue is identical in structure with that lining the rest of the oral cavity. We evaluated LMGs for urethroplasty. From January 2001 to September 2004, 8 men 34 to 65 years old (mean age 46.1) with urethral strictures 1.5 to 4.5 cm long were selected for 1-stage dorsal onlay urethroplasty. The site of the harvest graft was the lateral mucosal lining of the tongue. Postoperatively all patients were followed with urethrography, uroflowmetry, cystourethrography and flexible urethroscopy after 3 and 12 months. Successful reconstruction criteria were peak flow rate greater than 15 ml per second and no need for postoperative urethral dilation. Median followup was 18 months (mean 22.1, range 3 to 47). Seven cases were successful. One patient had a partial urethral stricture. In successful cases cystourethrography revealed no significant graft contractures or sacculations and at flexible urethroscopy LMG was almost indistinguishable from native urethra. There were no pain, esthetic or functional complications at the donor site. Harvesting the LMG is feasible and easy to perform. Compared with the buccal mucosal graft the LMG seems to be associated with less postoperative pain and a minor risk of donor site complications. These preliminary functional and esthetic data are satisfactory.

Anastomotic Urethroplasty For Bulbar Urethral Stricture: Analysis Of 168 Patients

We reviewed our experience with anastomotic urethroplasty for anterior urethral stricture. A chart review revealed 168 patients 6 to 82 years old (mean age 38) with at least 6 months of followup (mean 70, range 6 to 291) after anastomotic urethroplasty. Average stricture length was 1.7 cm. Of the 168 patients stricture recurred in 8 (5%) but was managed by direct vision internal urethrotomy or a single dilation in 5, while repeat urethroplasty was required in 3 (2%). In these 3 cases extenuating circumstances included patient dislodgment of the catheter with attempts to replace it that disrupted repair, a history of urethrocutaneous fistula and periurethral abscess, and previous irradiation complicating the stricture in 1 each. Other complications were uncommon, such as transient thigh pain or numbness in 3 patients (2%), small wound dehiscence in 2 (1%), and scrotal hematoma, erectile dysfunction and self-limited pulmonary edema in 1 (less than 1%) each. Anastomotic urethroplasty for anterior stricture has a high success rate of 95%. It is technically straightforward and complications are uncommon. Cure by anastomotic urethroplasty should be strongly favored over long-term management by direct vision internal urethrotomy or dilation.

BUCCAL MUCOSA URETHROPLASTY FOR THE TREATMENT OF BULBAR URETHRAL STRICTURES

We report the results of urethroplasty with a free graft of buccal mucosa as a dorsal onlay for the treatment of bulbar urethral strictures. Since June 1994, 30 patients with bulbar urethral strictures have been treated with buccal mucosa urethroplasty. Urethroplasty was performed with a free graft of buccal mucosa using a ventral onlay in the first 7 patients and a dorsal onlay in 23. Dorsal urethrotomy was performed with a Sachse urethrotome after the bulbar urethra was separated from the corpora. The buccal mucosa onlay was sutured to the urethra and corpora cavernosa to ensure a patent urethra. At 20-month followup (range 3 to 50) the success rate was 96% (29 of 30 patients). Urethral stricture recurred in only 1 of 7 patients in the ventral onlay and none of 23 in the dorsal onlay group. Preliminary results of urethroplasty for bulbar urethral strictures with a dorsal onlay graft of buccal mucosa are excellent. Longer followup is needed to evaluate definitive results.

A one-stage dorsal free-graft urethroplasty for bulbar urethral strictures.

To report the use of one-stage dorsal free-graft urethroplasty to reduce the incidence of urethrocele. From 1990 to 1994, 20 men (age range 21-86 years) underwent a one-stage dorsal free-graft urethroplasty of bulbar urethral strictures (iatrogenic in 12, traumatic in three, inflammatory in three and unknown in two). All patients except one had been treated previously by optical urethrotomy from one to 14 times. Temporary fistulae were detected on post-operative urethrography in three patients with particularly long grafts, but they all resolved spontaneously. Within a mean follow-up of 46 months, only one patient had a short recurrent stricture, which was treated successfully by optical urethrotomy. Two patients complained of post-voiding dribbling, but radiographic studies never showed graft weakening and the urinary flow rate was always > 14 mL/s. Free skin grafts can be applied successfully to the dorsal aspect and by doing so the complications of urethral reconstruction can be reduced.
