title: Long-term efficacy of a self-retaining intraurethral catheter for the treatment of prostatic obstruction.
abstract: BACKGROUND
  Transurethral prostatectomy is a standard treatment modality for infravesical obstruction with benign prostatic hyperplasia. However, some patients cannot undergo this procedure, so alternative devices or surgical procedures have recently been developed.
  
  
  METHODS
  We treated 26 patients with prostatic outflow obstruction by placement of a self-retaining intraurethral catheter (IUC). All patients had coexisting medical complications which contraindicated transurethral prostatectomy.
  
  
  RESULTS
  In the short-term, the treatment was successful in 96.2% of the patients, however, longer follow-up demonstrated a significant failure rate, and the 3-year success rate declined to 12.5%. The majority of late failures were associated with urinary tract infections.
  
  
  CONCLUSIONS
  These results showed that although placement of an IUC to treat prostatic obstruction was effective in the short-term, its long-term efficacy was highly limited.
