title: Success of de novo reimplantation of the artificial genitourinary sphincter.
abstract: OBJECTIVE
  We evaluate our experience with de novo reimplantation of the artificial genitourinary sphincter with a particular emphasis on mechanical and nonmechanical failure rates. De novo reimplantation is defined as implantation of an artificial sphincter following removal of a previously placed sphincter for erosion and/or infection and a waiting period of several months.
  
  
  METHODS
  A retrospective analysis of more than 400 patients with an artificial sphincter revealed 23 who underwent de novo reimplantation between January 1983 and October 1998. All patients were men with a mean age of 66.5 years (range 16 to 88) and all had a urethral cuff. Reasons for cuff removal were erosion in 12 cases (52.2%), infection in 10 (43.5%) and intraoperative urethral injury in 1 (4.3%). Mean waiting period was 6.8 months (range 1.5 to 32) between explantation and de novo reimplantation. Mean followup was 32.6 months (range 1 to 108).
  
  
  RESULTS
  Of the 23 patients 20 (87%) had no mechanical or nonmechanical failures and 3 (13%) had nonmechanical failures, including 2 patients (8.7%) whose cuff eroded into the urethra and 1 (4.3%) who had recurrent urinary incontinence which was successfully treated with implantation of a tandem cuff. There were no mechanical failures or infections in this group of patients.
  
  
  CONCLUSIONS
  Our study suggests that de novo artificial sphincter reimplantation is an excellent treatment option. It is safe and associated with complication rates that are comparable to those of primary implantation.
