Series Reached 500 Patients With Highly Successful Results
The first patient underwent surgery in April 1982 and since
then more than 500 patients
have followed. They have come from almost every state in the Union and from
Israel, Germany, The Netherlands, Italy,
Puerto Rico and Iceland. Moreover,
urologists from across the nation and
around the world have visited Hopkins
to learn the operation and now the procedure is being performed at major medical centers
worldwide.
The surgical
technique has been described in detail in
medical literature and has been the
subject of two movies, one of which recieved the coveted Golden Eagle Award
the Council on International Non-theatrical Events. Over the last five years,
we have learned much about the surgical
technique and have made minor modifications in the procedure.
Overall, 74 percent of the patients
have retained potency. Of those who
actually were potent, approximately
40 percent were able to resume intercourse within three months after surgery,
58 percent by six months, 70 percent by
nine months and 95 percent by one year.
During the second year of follow-up, 99
percent of the patients who were eventually potent were successful by 18
months and the final patients achieved
success at two years. Most patients experience improvement in sexual function
over the next several years following surgery. This should encourage patients who
are not yet back to normal.
The return of sexual function correlates with both the age of the patient at
the time of surgery and the extent of his
disease (Table 1). Potency returned in the two patients in their thirties, in 79 percent of
men in their forties, 85 percent of
men in their fifties, 64 percent of men in
their sixties, but in only 14 percent of
men in their seventies. Overall, 74 percent of patients are potent. Based on
clinical stage, potency returned in 93
percent of patients with stage AI disease, 72 percent of stage A2, 92 percent
of B1 nodules, 72 percent of stage B1
and 56 percent of stage B2 patients.
With advancing clinical stage, it is more
likely that the tumor extends beyond the
prostate, thereby necessitating resection
of one or both neurovascular bundles. As
a result, one would expect that potency
rates would be lower. For example, in
virtually all men with stage AI disease,
the cancer is confined to the prostate.
This suggests that almost all men with
clinical stage AI disease should have excellent return of sexual function. Conversely,
the reduced rate of potency in
men with stage B2 disease indicates that
attempts at resection of more advanced
tumors result in greater injury to the pelvic nerve plexus.

We've learned that it is possible to
widely excise one neurovascular bundle
and maintain potency Sixty-nine percent
of men who underwent this procedure
with wide excision of one neurovascular
bundle are potent postoperatively. We
now use the information in Table 1 preoperatively in advising patients, based upon
their age and stage of their lesion, as to the likelihood for the postoperative return
of sexual function.
