OBJECTIVES: 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. PATIENTS AND 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. CONCLUSION: Previous BOS does not affect the medium-term outcomes after LRP.
