title: Previous bladder outlet surgery does not affect medium-term outcomes after laparoscopic radical prostatectomy.
abstract: OBJECTIVE
  To investigate the effect of previous bladder outlet surgery (BOS) on the peri-operative variables of patients having laparoscopic radical prostatectomy (LRP), as reported evidence as to whether BOS affects the outcome of RP is contradictory.
  
  
  METHODS
  Of 600 consecutive patients attending for LRP from March 2000 to January 2006, 558 had had no surgery (NS) and 42 (7.0%) had a history of BOS (transurethral prostatectomy in 35, 5.8%; bladder neck incision in seven, 1.2%). All patients had clinical stage < or = T3aN0M0 prostate cancer and had their procedure performed or supervised by the same surgeon.
  
  
  RESULTS
  Patients with previous BOS had a significantly greater age (mean 64.6 vs 61.8 years, P = 0.008), duration of catheterization (mean 13.7 vs 10.5 days, P = 0.003), proportion of pT3a tumours (16.7% vs 4.5%, P = 0.009) and potency rates at > or = 24 months (P < 0.001). Patients with previous BOS had a significantly lower body weight (mean 79.7 vs 83.0 kg, P = 0.05) and prostate weight (mean 46.7 vs 58.6 g, P = 0.01). Although patients with previous BOS had poorer continence at 3 months (61% vs 91%, P < 0.001), continence rates were similar in the two groups after this.
  
  
  CONCLUSIONS
  Previous BOS does not affect the medium-term outcomes after LRP.
