[Total prostatectomy with preservation of erection. Surgical technic]

The authors describe their technique to preserve the erector nerves during a radical retropubic prostatectomy. In the first part, the different phases of the operation are described. The 2nd part consists of discussion based on the author's experiences (20 cases of nerve preservation in a series of 115 radical prostatectomies). The authors stress the insufficient oncological follow-up and the risk of an incorrect indication due to understaging of the cancer in pre-operative period.
