Abstract
One of the major and disconcerting complication of
prostatectomy is impotence but the cause of impotence among men
undergoing surgical prostatectomy or transurethral resection of the
prostate (TURP) is still controversial.
This study included 100 potent patients who presented to
Urology Department, Benha Faculty of Medicine with symptoms of
benign prostatic hyperplasia. They were divided into two groups
according to management: 50 patients underwent TURP group (1)
and 50 patients underwent transvesical open prostatectomy group
(II).
By usmg of SPACE device (single potential analysis of
cavernous electrical activity) as a non invasive method for
diagnosis of cavernous autonomic dysfunction after TURP and
transvesical open prostatectomy first, second and third month
postoperatively.
Only four patients (8%) out of 50 patients, become totally
impotent 3 months after TURP which gave abnormal response of
SPACE pattern in the form of decrease amplitude less than 100 uv
and no synchronization of spike in both cavernous bodies.
Summary & conclusion
81
On the other hand 92% (46 patients) were given normal
response of SPACE in the form of increase the amplitude of
potentials 250-500 uv and synchronization of spikes in both
cavernous bodies by follow up the patients first, second and third
month after TURP.
However, in case of transvesical open prostatectomy, no
change of potency by SPACE pattern which gave normal response
in the first, second and third month postoperatively.
Conclusion:
In this study it has been found that potency is affected by
TURP, 8% (4 patients) became totally impotent 3 months postoperatively.
•
The following factors are incriminated; the smaller size of the
prostate the more is the transmission of heat during cutting and
cauterization, secondly excessive cauterization especially at the
apex of the prostate and resection down to the capsule.
The heat generated due to these factors do affect the
cavernous nerves. Also, it has been found that perforation of the
capsule with subsequent extravasation do affect potency due to
injury and fibrosis of the cavernous nerves.
On the other hand, there was no effect on potency after
transvesical open prostatectomy by follow up of the patients first,
second and third months postoperatively.
