title: Ventral penile curvature following radical pelvic surgery: a variant of urethral manipulation syndrome.
abstract: OBJECTIVE
  Urethral manipulation syndrome (UMS) describes ventral penile curvature and urethral stricture disease that develop following repeated episodes of urethral manipulation. We describe a variant of this syndrome, in which the presence of an indwelling catheter following radical pelvic surgery led to a marked penile curvature without clinically apparent urethral stricture disease.
  
  
  METHODS
  We identified 4 patients in whom ventral penile curvature developed following radical pelvic surgery. Three patients underwent radical retropubic prostatectomy and the fourth patient underwent radical cystoprostatectomy with creation of a neobladder to the urethra. All were treated with 3 weeks of catheter drainage postoperatively. Each patient reported straight erections prior to surgery.
  
  
  RESULTS
  These patients came to prosthesis surgery between 7 months and 3 years after their pelvic procedure. Each patient was noted to have ventral penile curvature when artificial erection was induced. Curvature was secondary to scarring between the anterior corpus spongiosum and the overlying ventral tunica albuginea in the mid- to proximal penile shaft. It was necessary to mobilize the urethra off the corpora and to incise the scarred tunica to obtain a satisfactory result at the time of prosthesis placement. In 3 cases, GoreTex was needed to bridge the corporeal defect.
  
  
  CONCLUSIONS
  These cases represent a variant of UMS in which catheter drainage leads to scarring of the ventral tunica albuginea, resulting in ventral penile curvature. In view of the increasing number of radical pelvic procedures being performed, this potential complication must be recognized, as aggressive corporeal reconstruction with urethral mobilization is needed if subsequent prosthesis surgery is undertaken.
