Nerve-sparing surgery is a type of surgery that attempts to save the nerves near the tissues being removed. [ 1 ] It is commonly applied in radical retropubic prostatectomy , a surgical treatment for prostate cancer, in which damage to nerves during surgery can lead to complications including urinary incontinence and impotence .
Prostatectomy (from the Greek προστάτης prostátēs, "prostate" and ἐκτομή ektomē, "excision") is the surgical removal of all or part of the prostate gland. This operation is done for benign conditions that cause urinary retention, as well as for prostate cancer and for other cancers of the pelvis .
Nerve-sparing surgery—Select individuals will be eligible for nerve-sparing surgery. Nerve-sparing surgery attempts to protect the cavernous nerves of penis, which control erection. These nerves are very thin and fragile and run next to the prostate and may be destroyed during surgery, leading to impotence.
Rates for impotence when comparing radiation to nerve-sparing surgery are similar. Radiation has lower rates of incontinence compared with surgery, but has higher rates of occasional mild rectal bleeding. [33] Men who have undergone external beam radiation therapy may have a slightly higher risk of later developing colon cancer and bladder ...
Patrick C. Walsh is an American urologist, researcher and writer, best known for developing "the anatomic approach to radical prostatectomy", involving nerve-sparing techniques which reduced the likelihood of impotence and urinary incontinence.
Laparoscopic radical prostatectomy (LRP) is a form of radical prostatectomy, an operation for prostate cancer. Contrasted with the original open form of the surgery , it does not make a large incision but instead uses fiber optics and miniaturization.
The recent decline in rates follows a mostly upward climb since the average rate on a 30-year mortgage slid to a two-year low of 6.08% in late September after the Federal Reserve cut its main ...
In prostate cancer, PNI in needle biopsies is poor prognosticator; [2] however, in prostatectomy specimens it is unclear whether it carries a worse prognosis. [4]In one study, PNI was found in approximately 90% of radical prostatectomy specimens, and PNI outside of the prostate, especially, was associated with a poorer prognosis. [5]
