Traumatic posterior urethral injury and early primary endoscopic realignment: evaluation of long-term follow-up.
ABSTRACT The management of complete or partial posterior urethral disruption is controversial and much debate continues regarding immediate versus delayed definitive therapy. We further analyze our experience and long-term results using early endoscopic realignment.
Between April 1991 and June 1995, 8 men with posterior urethral avulsion, either complete or partial and secondary to blunt trauma and pelvic fractures, presented to our institution. A variety of endourologic techniques were employed to achieve urethral continuity while attempting to minimize stricture formation, incontinence, and impotence.
After a mean of 50.4 months (range 35 to 85) of follow-up, 7 men (87.5%) are continent, with 2 of those requiring intermittent self-dilation ranging from once every 7 days to once a month. One patient required conversion to an open perineal urethroplasty. Of the 8 patients, 5 (62.5%) are potent, and 2 others achieve adequate erections for intercourse using intracorporeal injections. Four of the 8 have required subsequent internal urethrotomies with eventual voiding stabilization over the course of 1 2 months. Average time to realignment was 9.5 days (range 0 to 19).
Primary endoscopic realignment offers an effective method for treating traumatic urethral injuries. Our long-term follow-up provides further support for use of this technique by demonstrating that urethral continuity can be established without increased incidence of impotence, stricture formation, or incontinence. By achieving early and minimally invasive realignment, we seem to lessen the severity of stricture disease that almost uniformly afflicts those patients who undergo delayed repair. If a minimally invasive technique should fail, it does not seem to delay nor does it preclude further management using open techniques.

ABSTRACT: Objectives.Traumatic avulsion of the posterior urethra represents a challenging reconstructive problem that traditionally has been managed by the transpubic or transperineal approach. We report the advantages of endourologic techniques to reconstruct short posterior urethral disruptions based on the principles of establishing proximal urethral control and balloon dilation of the newly constructed urethra.Methods.Endourologic urethroplasty consists of: (1) antegrade flexible cystoscopy orantegrade passage of a Goodwin sound, (2) retrograde urethrotomy to light or to tip of Goodwin sound, facilitated by C-arm fluoroscopy, (3) establishment of urethral continuity by passage of a guide wire, (4) balloon dilation of the newly established urethra to 24 to 30 F over a length of 4 cm, and (5) long-term urethral stenting (4 to 8 weeks) with a silicone Foley catheter.Results.In four men initially managed by suprapubic cystostomy, endourologic reconstruction was performed. The mean blood loss was 250 mL, and mean length of hospitalization was 5.4 days. All patients were continent and three were potent over a mean follow-up of 10.5 months. Uroflowmetric monitoring showed satisfactory voiding patterns with subsequent minor endoscopic revisions required in three patients.Conclusions.The technical advantages of this method include stabilization and identificationof the proximal urethra, intraoperative shortening of the urethral gap to facilitate the urethrotomy, and radial distention of the urethra by balloon dilation. We conclude that endourologic methods provide a safe and effective initial treatment of urethral avulsion.Urology 01/1994; 44(1):100-105. · 2.42 Impact Factor

ABSTRACT: The types of fracture of the bony pelvis are categorized, and a system for diagnosis and treatment is recommended which should prevent many strictures and make those which do develop, easier to repair secondarily. This system of treatment should reduce trauma to the nerves and blood vessels.Urology 12/1982; 20(5):467-70. · 2.42 Impact Factor

ABSTRACT: Major urethral injuries from external trauma are complex problems of diagnosis and treatment. Complications resulting from injury, failed diagnosis, and inappropriate therapy include stricture, impotent, and incontinence. Opinions differ as to whether immediate suprapubic cystostomy followed by later reconstruction is preferable to immediate direct urethral realignment. A review of 30 patients with urethral injuries is presented, 27 male and three female, 29 from blunt trauma and one gunshot. Initial suprapubic cystostomy alone was used in 26 male patients, 21 with prostatomembranous disruption and five with straddle injury. Prostatomembranous reconstruction in 14 complete urethral transections resulted in one residual stricture, two impotent patients, and no incontinence. Partial prostatomembranous disruption and straddle injuries had insignificant residual stricture, none requiring dilation or reconstruction. The results of this management approach appear superior to those of immediate urethral realignment. Advantages of immediate suprapubic cystostomy are: 1) simplified early approach in management, and 2) successful elective reconstruction of major prostatomembranous injuries with low incidence of stricture, impotence, and incontinence.The Journal of trauma 05/1981; 21(4):291-7. · 2.35 Impact Factor
