The objective of the study was to evaluate the long-term results of retroperitoneal laparoscopic radical prostatectomy (LRP). From 2001 to 2005, 550 consecutive patients underwent a laparoscopic extraperitoneal prostatectomy in our department. Continence and erectile function were analysed prospectively by a self-administrated questionnaire. Mean operating time was 188 min, mean bladder catheterisation time 5.9 days, mean hospital stay 4.6 days Pathological stage was pT2 in 55.8%, pT3a in 29.6%, pT3b in 9.1% and pT4a in 5.4% tumours. Positive surgical margins were 17.9% for pT2, 44.8% for pT3 tumours and 71.4% for pT4a tumours. Five years survival without biochemical progression was 78.8%. After 24 months of follow-up, diurnal continence rate was 91%, and potency rate was 64% when both neurovascular bundles were preserved, 78.6% when the patients were younger than 60 years. LRP is now a standardised procedure. An extraperitoneal approach combines the advantages of a laparoscopic procedure with those of an extraperitoneal approach.
