title: Evaluation of urinary continence and voiding function: early results in men with neo-urethral modification of the Hautmann orthotopic neobladder.
abstract: OBJECTIVE
  At our institution we use the Hautmann orthotopic bladder replacement with a chimney and neo-urethral modification. A neo-urethral tube allows tension-free intestino-urethral anastomosis, thus providing application of this procedure for patients who may otherwise not qualify due to the inability of the small bowel to reach the urethra. However, this neo-urethral tube may also enhance continence by providing significant intra-abdominal urethral length. Conversely, such a modification may be associated with a higher degree of urinary retention. Early evaluation and reporting on the results of this procedure appear warranted.
  
  
  METHODS
  From April 1996 to March 2000, 14 consecutive male patients underwent cystoprostatectomy and urinary reconstruction with Hautmann repair using chimney and neo-urethral modifications. We performed a retrospective analysis of urinary function and continence with data obtained from patient questionnaires completed preoperatively and at each postoperative office visit. The examining physician chart notes were reviewed for information about urinary retention. The American Urological Association symptom score and voiding bother index were used to assess urinary function and bother, respectively. Urinary continence was defined as the complete absence of any form of urinary leakage protection.
  
  
  RESULTS
  Of the 14 patients 12 were completely continent day and night, with a median followup of 17 months. There were 2 patients who wore pads less than 7 months after surgery. Improvement of urinary continence appeared to continue up to 12 months postoperatively. Despite this encouraging effect, when our data were compared to the published literature, we noted a somewhat increased incidence of patients requiring clean intermittent catheterization to manage significant post-void urinary residuals. We had no patients with urethro-intestinal strictures who required clean intermittent catheterization.
  
  
  CONCLUSIONS
  The neo-urethral tube modification appears to have a significant and favorable impact on urinary continence while seeming to be associated with a trend towards an increased rate of chronic urinary retention. Longer followup will be required to determine whether this higher rate of chronic urinary retention will remain stable or change with time.
