Conclusion: We found no significant differences between retropubical and laparoscopic RP in the oncologic and functional variables analyzed. Nevertheless, our experience shows a distinct benefit in favour of the laparoscopic approach in relation to bleeding and recovery rate. Though retropubical RP has a shorter operating time, we believe this variable depends on the learning curve still developing for laparoscopic RP. According to our literary review, this is the first publication in Chile that compares both techniques.
