Tunica Vaginalis Lesion Excision
What is
Tunica Vaginalis Lesion Excision?
The
tunica vaginalis is the serous covering of the
testis. It is a pouch of serous membrane,
derived from the saccus vaginalis of the
peritorneum, which in the fetus preceded the
descent of the testis from the abdomen into the
scrotum.

defects and treating infection.

Candidates for Tunica Vaginalis Lesion Excision
Scrotal approach with excision or eversion and
suturing of the tunica vaginalis and is
recommended for chronic noncommunicating
hydroceles.

Your Consultation
Ultrasonography is the primary
modality for imaging scrotal lesions. It
provides excellent spatial resolution and has
been shown to be nearly 100% sensitive in the
identification of scrotal masses.

The
Tunica Vaginalis Lesion Excision Procedure
The
surgery involves making a small incision in the
groin or inguinal area and then draining the
fluid and closing off the opening to the tunica
vaginalis.

Recovery
Immediately following surgery, the patient will
be taken to a recovery area and checked for any
undue bleeding from the incision. Body
temperature and blood pressure will be
monitored. Patients will usually go home the
same day for a brief recovery period at home.
Follow-up appointments are usually scheduled for
several weeks after surgery so that the doctor
can check the incision for healing and to be
sure there is no infection. The patient may
notice swelling for several months after the
procedure; however, prolonged swelling, fever,
or redness in the incision area should be
reported to the surgeon immediately.

Risks
Injury
to spermatic vessels can occur and affect the
man's fertility. As with all surgical
procedures, reactions to anesthesia, bleeding
from the surgical incision, and internal
bleeding can also occur.

Frequently Asked Questions
Q:
What is the tunica vaginalis?
A:
The tunica vaginalis invests all but the
posterior aspect of the testis and is
composed of a visceral portion around the
testis and a parietal layer against the
scrotal wall. The visceral layer of
the tunica vaginalis blends imperceptibly with
the tunica albuginea. Several
pathologic processes can involve this
space, predominantly in the form of fluid
collections. Hydroceles occur when
serous fluid accumulates between the parietal
and visceral layers of the tunica
vaginalis. A small amount of fluid is
normal and has been noted at sonography in up to
86% of asymptomatic men. Hydroceles
may be congenital or acquired. Congenital
hydroceles occur when there is incomplete
closure of the processus vaginalis.
Congenital hydroceles are present in 6% of
male infants at delivery but in less than
1% of adults, since most hydroceles
resolve by 18 months of age. Patients with
a patent processus vaginalis are at
increased risk for developing an
inguinal hernia.
Q:
What are hermatoceles?
A:
Hematoceles (accumulation of blood within the
tunica vaginalis) may be either acute
or chronic, and they have a more complex
heterogeneous appearance with echogenic
debris and septations. They often
exert mass effect, distorting the contour of the
testis
Q:
What causes hermtoceles?
A:
Possible causes most often include trauma,
torsion, tumor, and surgery. The trauma
may be quite minor and go unnoticed,
as may occur with bike riding or weight lifting.
Frequently in such cases, a varicocele is
an associated finding. Presumably,
the minor trauma results in rupture of one of
the dilated vessels.
