### Question: Robot-assisted vs pure laparoscopic radical prostatectomy: are there any differences?

### Context: 1: To compare our experience of pure laparoscopic radical prostatectomy (LRP) with robot-assisted radical prostatectomy (RAP).
2: The two techniques were compared retrospectively in 100 patients with localized prostate cancer who had LRP or RAP (50 each). Both groups were similar in age, serum prostate-specific antigen level, Gleason score and clinical stage. Their charts were reviewed, collating intraoperative data and early functional outcome.
3: The mean surgical time for LRP and RAP was 235 and 202 min (P>0.05) and mean (95% confidence interval) blood loss 299 (40) and 206 (63) mL (P = 0.014), with no transfusions in either group. The positive margin rate did not differ significantly (14% LRP and 12% RAP) and there was no biochemical recurrence in either group. Early functional outcomes were similar.


###Response: Both LRP and RAP are technically demanding, but feasible, with the patient clearly benefiting. There were no major surgical differences between the techniques, but RAP is more costly.
