The self-retaining perineal
retractor is a tool used in the radical perineal
prostatectomy for the treatment of prostate cancer.
The prostate is removed through a single incision across
the perineum. After making the incision, the surgeon
will use the self-retaining perineal retractor to hold
the incision open and facilitate the removal of the
prostate gland. Because the incision is much smaller
in the radical perineal prostatectomy than in the retropubic
prostatectomy, recovery is usually shorter and blood
loss is less.
