[11C]choline-PET seems to be useful for re-staging prostatectomy cases with increasing serum PSA levels. It is superior to [18F]fluorodeoxyglucose-PET and complementary to conventional imaging but with the advantage of staging disease at a single step.

. All patients were operated by the same laparoscopically naive surgeons. The comparison was by matched-pair analysis. RESULTSThe baseline characteristics of the two groups were equivalent, although there was a higher percentage of patients with pT3/pT4 disease in the RRP group. As a proxy for oncological outcome, positive surgical margins were equivalent in the two groups (22% RARP vs 25% RRP, P = 0.77). The overall mean (range) surgical duration was significantly longer in RARP group, at 215 (165-450) min vs 160 (90-240) min in the RRP group ( P < 0.001). However, RARP had a statistically significant advantage over RRP for estimated blood loss, of 200 vs 800 mL ( P < 0.001), duration of catheterization (6 vs 7 days P < 0.001) and length of stay (3 vs 6 days, P < 0.001) The 3, 6 and 12-month continence rates were 70%, 93% and 97% vs 63%, 83% and 88% after RARP and RRP, respectively ( P = 0.15, 0.011 and 0.014). The 3, 6 and 12 month overall potency recovery rate was 31%, 43% and 61% vs 18%, 31% and 41%, after RARP and RRP, respectively ( P = 0.006, 0.045 and 0.003). CONCLUSIONOur initial experience showed the feasibility of RARP in a laparoscopically naive centre. RRP seems to be a faster procedure, whereas RARP provided better results in terms of estimated blood loss, hospitalization and functional results. The early oncological outcome seemed to be equivalent in the two groups.

Analysis of a large data set from multiple institutions shows that surgical removal of symptomatic large prostatic adenomas can be carried out with good outcomes by using robot-assisted laparoscopy.
