title: Does the success of ureterointestinal implantation in orthotopic bladder substitution depend more on surgeon level of experience or choice of technique?
abstract: OBJECTIVE
  We attempted to determine the relative risk of ureterointestinal anastomosis using 2 antireflux techniques of orthotopic bladder substitution, and we assessed the degree to which success is determined by surgeon experience.
  
  
  METHODS
  A total of 120 patients underwent surgery, including 74 with the Hautmann (Le Duc) technique and 46 with a somewhat modified Studer (Nesbit/Studer) technique. The urologists who performed the operations were classified as expert, skilled and learner. Evaluation was done retrospectively. All patients in the Studer group, except 3 who died and 1 who was lost to followup, were monitored a minimum of 12 months.
  
  
  RESULTS
  There was a 20.4% rate of nonneoplastic obstructions in the 142 ureters reimplanted with the Le Duc technique (Hautmann group). The variation in obstruction rates of 16.7, 18.2 and 25%, respectively, for expert, skilled and learning surgeons was statistically insignificant. Only 3 nonneoplastic obstructions (3.6%) developed in the 83 ureters reimplanted with the Nesbit/ Studer technique (Studer group). The variation in obstruction rates of 5.1, 0 and 3.6%, respectively, for expert, skilled and learner surgeons was statistically insignificant.
  
  
  CONCLUSIONS
  The Nesbit/Studer technique results in a generally lower rate of ureterointestinal anastomotic stricture than the Le Duc technique. Using the Le Duc technique there was no statistically significant correlation between incidence of obstruction and surgeon level of experience, indicating that obstruction with this technique probably arises from other factors.
