GU Procedures
Operative Sequence
Circumcision
• Overall Purpose of Procedure:
– Performed to prevent infection and inflammation
of the glans.
– a lower risk of urinary tract infections, penile
cancer and sexually transmitted diseases.
– Circumcision may also be used to treat Phimosis:
a constriction of the opening of the foreskin so
that it cannot be drawn back over the tip of the
penis.
Circumcision
• Define the procedure:
– Circumcision is the removal of some or all
of the foreskin (Prepuce) from the penis

• Major Arteries:
– The dorsal arteries, which
run in the interval between
the corpora cavernosa on
each side of the deep dorsal
vein.
– The dorsal and deep
arteries are branches of the
internal pudendal arteries.
– The deep arteries are the
principal vessels that supply
the cavernous spaces
(erectile tissue) in the three
corpora.
Circumcision
• Major Veins:
– Blood from the
cavernous spaces is
drained by a venous
plexus that joins the deep
dorsal vein located in the
deep fascia.
• Major Nerves:
– pudendal nerve.
GU Procedures

Orchidopexy
(aka – Orchiopexy)
Orchidopexy
• Define the procedure:
• to move an undescended testicle into the scrotum
• Overall Purpose of Procedure:
• Relieve Cryptorchidism - a medical term referring to
absence from the scrotum of one or both testes. This
usually represents failure of the testis to move, or
"descend," during fetal development. Can lead to
sterility due to heat in the abdomen.
• Orchiopexy can also be performed to resolve a
testicular torsion. If caught early enough and the blood
supply can be restored to the testicle, this operation can
be performed to prevent further occurrence of torsion.

Simple Nephrectomy
Simple (Open) Nephrectomy
• Overall Purpose of Procedure:
• The reasons for performing a simple
nephrectomy include:
• Cancer in the kidney.
• Large stones in the kidney.
• The kidney may be damaged and very small,
causing high blood pressure.
• The kidney may have an infection that
antibiotic treatment cannot cure.
Simple vs Radical
• A simple nephrectomy is indicated in patients with
irreversible kidney damage due to symptomatic chronic
infection, obstruction, calculus disease, or severe traumatic
injury.
• Simple nephrectomy is also indicated to treat renovascular
hypertension due to noncorrectable renal artery disease or
severe unilateral parenchymal damage caused by
nephrosclerosis, pyelonephritis, reflux dysplasia, or
congenital dysplasia of the kidney.
• Sometimes, just a part of the kidney may be removed
Simple vs Radical
• Radical nephrectomy is the treatment of choice for
localized renal cell carcinoma (RCC). In certain
circumstances, radical nephrectomy is also
indicated to treat locally advanced RCC and
metastatic RCC.
• Radical nephrectomy remains the procedure of
choice for surgically resectable lesions.
• Your surgeon will also take out the adrenal gland
and some lymph nodes.
Simple Nephrectomy
• Define the procedure:
• A simple nephrectomy is removal of an entire
kidney.

Cysto and TURP
Suprapubic Prostatectomy
Cystoscopy
• Cystoscopy is a
procedure that
allows the doctor to
look at the inside of
the bladder and the
urethra using a thin,
lighted instrument
called a cystoscope
Cysto
Cysto
Cysto
• Cystoscopy may be done to:
• Find the cause of symptoms such as blood in
the urine (hematuria), painful urination
(dysuria), urinary incontinence, urinary
frequency or hesitancy, an inability to pass
urine (retention), or a sudden and
overwhelming need to urinate (urgency).
Cysto
• Find the cause of problems of the urinary tract, such
as frequent, repeated urinary tract infections or
urinary tract infections that do not respond to
treatment.
• Look for problems in the urinary tract, such as
blockage in the urethra caused by an enlarged
prostate, kidney stones, or tumors
• Evaluate problems that cannot be seen on X-ray or to
further investigate problems detected by ultrasound
or during intravenous pyelography (IVP), such as
kidney stones or tumors.
Cysto
• Remove tissue samples for biopsy.
• Remove foreign objects.
• Place ureteral catheters (stents) to help urine flow from the
kidneys to the bladder.
• Treat urinary tract problems. For example, cystoscopy can be
done to remove urinary tract stones or growths, treat bleeding in
the bladder, relieve blockages in the urethra, or treat or remove
tumors.
• Place a catheter in the ureter for an X-ray test called retrograde
pyelography. A dye that shows up on an X-ray picture is
injected through the catheter to fill and outline the ureter and the
inside of the kidney.


(TRANSURETHRAL RESECTION OF
PROSTATE).
During transurethral resection of the prostate
(TURP), an instrument is inserted up the
urethra to remove the section of the prostate
that is blocking urine flow.

TURP is now the most common surgery used
to remove part of an enlarged prostate. Open
prostatectomies (in which an incision is made
into the abdomen) generally are needed only
when the prostate is very large.



Old School: Glycine is fluid of choice
New School: NACL!!! Usually the team will
not use NACL due to the fact that they can’t
use the electrode needed for a TURP with
NACL present. However, too much NACL
will throw the fluid balance of your patient off.
Your pt can end up with fluid toxicity!
New systems are bipolar instead of monopolar.
Suprapubic Prostatectomy
Suprapubic Prostatectomy
Suprapubic Prostatectomy
• Overall Purpose of Procedure:
– Performed to treat BPH (benign prostatic
hypertrophy) and for cancer of the prostate.
– Inguinal nodes may be removed for diagnosis of
metastasis.
Suprapubic Prostatectomy
• Define the procedure:
– The prostate gland is removed via a suprapubic
(above the pubic bone) incision.
– Three primary approaches are commonly employed:
• Suprapubic - removal through an incision above
the pubis and through the urinary bladder;
• Retropubic – same incision as for suprapubic but
without entering the urinary bladder
• Transurethral (TRANSURETHRAL RESECTION
OF PROSTATE).
Radical vs Simple
• Radical vs Simple Prostatectomy
– Radical – nerve sparing
– Simple – not so much! Simple coring of the
prostate. No nerves spared.
Suprapubic Prostatectomy
• The major advantage of the suprapubic
approach over the retropubic approach is that
it permits better visualization of the bladder
neck and ureteral orifices and, therefore, is
better suited for patients with the following
conditions:
–
–
–
–
Enlarged, protuberant, median prostatic lobe
Bladder diverticulum
Large bladder calculi
Obesity (to a degree that makes access to the
retropubic space more difficult)

• Using 2-0 Vicral sutures on
5-8 circle tapered needles,
full thickness sutures are
placed at 12, 3, 6, and 9
o'clock positions through the
urethral mucosa, smooth
muscle, striated urethral
sphincter, and fascia. At the
6 o'clock position the suture
is placed with care to avoid
injuring the neurovascular
bundles, which are located
posterior to the striated
sphincter. At the 12 o'clock
position the suture
incorporates the anterior
dorsal vein/striated urethra
sphincter hood.

Penile Implant
Penile Implant
Implants
• Penile implants are artificial devices implanted
inside the penis that allow men with erectile
dysfunction (ED) to achieve an erection. They're
also sometimes used to treat Peyronie's disease, a
disorder that causes bent or painful erections.
• There are two basic designs of implants:
• Inflatable. Also called hydraulic, inflatable implants
can be pumped up to create an erection and then
deflated.
• Semirigid. These implants are always somewhat
firm.
History
• First introduced in the 1970s, penile
implants were the most reliable treatment
for erectile dysfunction until the 1980s
when medications injected into the penis
became available. In the 1990s, oral
agents such as sildenafil (Viagra) were
introduced.
There are two basic types of penile
implants
• 1) Semirigid rods.
• This type of implant is always firm. The
penis may be bent away from the body to
have sex and toward the body to conceal
the device.
Old School
• Old School manual
implant.
New School
2) Inflatable implants
• Three-piece implants use a fluid-filled reservoir
implanted under the abdominal wall, a pump-andrelease valve placed inside the scrotum, and two
inflatable cylinders inside the penis. Before sex, the
patient pumps the fluid from the reservoir into the
cylinders to cause an erection. After sex, the pt
release the valve inside the scrotum to drain the
fluid back into the reservoir.
• The two-piece model currently available in the
United States works in a similar way to a three-piece
design, but the fluid reservoir is part of the pump
mechanism implanted in the scrotum.
New School
• Pumps in
abdomen, thigh or
scrotum.
• In the United States, inflatable devices are
the most common type of penile implant.
• Three-piece inflatable devices are used in
about 70 percent of penile implants.
• Two-piece inflatable devices are used
about 20 percent of the time.
• Semirigid devices are the least used,
accounting for about 10 percent of
implants.
