Q
  • Sometimes circumcision is done for religious reasons and sometimes it’s a cosmetic preference.
  • Sometimes insurance companies pay for this procedure, and sometimes they don’t.
    It used to be thought that with that foreskin boys were at increased risk for urinary tract infections because sometimes that skin would flap over the opening. But we know now, based on the literature that there is zero increased risk of UTIs if the foreskin remains, so a lot of insurance companies now say there’s no need to actually remove it.
    Sometimes you will pay out of pocket for that.

A

A pus discharge with urination

97
Q

98
Q

How do you diagnose Benign Prostatic Hyperplasia (BPH)?

A
  1. Digital rectal exam
    - A physician or medical practitioner would insert usually one to two fingers into the rectum. In a normal rectal exam, you can not feel the prostate. So, if you do a digital rectal exam on somebody, and you palpate the prostate, in other words, you can feel it, that means it’s enlarged.
  • A rectal exam alone each year, once they get to the age of 50, is recommended as well as providing a stool sample and a prostate exam.
99
Q

How do you treat Benign Prostatic Hyperplasia (BPH)?

A
  1. Medications that block androgen are testosterone receptors that usually will shrink the size of the prostate
  2. Herbal Rx: saw palmetto berries
  3. Advanced cases require prostatectomy​ - remove the prostate gland

– The biggest side effect of this procedure is that the nerves that go to the prostate gland are the same nerves that go to the bladder.
It’s not uncommon for a male to have his prostate gland removed and become incontinent, it happens in about 15% of cases.

  1. TURP: removal of the prostate through the urethra​ which has a quicker recovery

– No need for an abdominal incision, same-day surgery, and fewer side effects than an actual abdominal incision

100
Q

True of False: Prostate cancer is the most common malignancy in males in the US.

A

True

101
Q

Symptom of “Prostate cancer”?

A

Abdominal pain

102
Q

How do you diagnose “prostate cancer”?

A
  1. Digital rectal exam
  2. CT scan
  3. PSA (Prostate Specific Antigen) count in blood
  4. Biopsy (T1, T2, T3, T4)​
103
Q

True or False: Prostate cancer is the most minor and is the one that is hardest to diagnose because a digital rectal exam is negative, meaning you can’t palpate the prostate, and the tumor isn’t large enough to push on the urethra or the bladder.

A

True

104
Q

The picture labeled “a” shows a digital rectal exam. When conducting the exam the physician would have one or two fingers inserted into the rectum. When the physician puts fingers in the rectum they should feel empty space. Conducting a rectal exam the physician can feel fecal material and can palpate for polyps for colon cancer. The prostate gland is pretty close to the opening so if the physician feels something here, that means the prostate gland is enlarged. Normally when fingers are inserted they should feel smooth. If a lump is felt it is a good indication that the prostate is enlarged. It doesn’t mean it’s cancerous but if it’s enlarged, there’s a good chance that you need further testing.

The picture labeled “b” - if a mass is felt or suspected or the patient has a family history of prostate issues, a biopsy will be taken of the prostate gland. The tissue taken from the biopsy will be tested for cancer cells.
The picture labeled “c” - the use of diagnostic ultrasound in connection with the biopsy tool can be used to see the structures and more specifically target the tissue to be exercised?

A
105
Q

How do you treat “prostate cancer”?

A
  1. Radiation
  2. Chemotherapy
  3. Removal
  4. “Watchful waiting”​
    —Genetic testing for tumor aggressiveness
    can evaluate the risk​
    — You can live for years with prostate cancer,
    once it metastasizes is when it usually
    becomes more fatal.
106
Q

True or False: Testicular cancer, unlike prostate that’s fairly prevalent, accounts for less than 1% of all cancers affecting males and usually presents in the age range of 25 to 45.

A

True

107
Q

Is there a genetic link to testicular cancer?

A

No

108
Q

Where does “testicular cancer” develop?

A

Germ cells inside the testicles

  • like prostate cancer it can metastasize
109
Q

What are the symptoms of “testicular cancer”?

A

– Most testicular cancer is at least initially screened by the patient themselves or by a partner of the patient.

— Men should be aware when anything seems abnormal, such as noticing a size difference in the right testicle to the left testicle. Although a patient often thinks it’s probably nothing, the worst thing that can happen is to have testicular cancer and find out it spread because it was diagnosed.

110
Q

How do you diagnose “testicular cancer”?

A
  1. 50% of the tumors, release an androgynous marker, meaning a blood test can identify a testosterone marker indicating there is a tumor
  2. Biopsy - if there are increased testosterone levels in the blood and perhaps a lump in the testicle, that would be checked out with a biopsy
111
Q

What are the treatments of “testicular cancer”?

A
  1. Surgical removal
  • implants are put inside
  1. Radiation or chemotherapy are typically done after the testicle has been removed if the tumor has spread at all to lymph nodes.
112
Q

Does cancer spread from one testicle to the next?

A

No, stays on one side of the body

113
Q

T0 stage of testicular cancer is when …

A

Cancer is contained within the seminiferous tubules in the testicle but has not invaded any other aspect of the testicle

114
Q

T1 stage of testicular cancer is when …

A

The tumor is now grown outside of the seminiferous tubules into other testicular structures and may have started growing outside of the testicle but has not invaded the lymph nodes

115
Q

T2 stage of testicular cancer is when …

A

The tumor has now invaded the lymph nodes but has not spread to distant parts of the body

116
Q

T3 stage of testicular cancer is when …

A

Cancer has spread to other locations and distant parts of the body

117
Q

What is “cryptorchidism”?

A

When one or both of the testes don’t descend into the scrotum

118
Q

Treatments for “cryptorchidism”?

A
  1. Most of the time this is not treated unless it is not corrected by one year on its own.
  2. Usually babies start to walk at about a year, and sometimes gravity will fix this condition.
  3. When babies are being carried when they’re, you know, they’re not upright all the time they’re not walking around, the testicles can slide back up into the abdomen.
  4. Surgery
119
Q

Surgery would be required to correct this if the testes are in the abdomen. Remember, the temperature of the human body is about 98.6 degrees and the temperature of the testicles is one to two degrees lower. That’s a perfect environment for sperm to develop sperm. Inside the abdomen, 98.6 degrees is too warm for sperm to develop. A testicle dislocated, or not descended into the scrotum, ‘s a common cause of infertility in males.

A
120
Q

You’ve probably heard this before you can actually dislocate your testicle. So in sports, that is the reason that male athletes often wear cups. Someone kicked hard enough, or hit with a ball, a club, a lacrosse stick baseball bat, etc. hit hard enough and at the right angle, could dislocate a man’s testicle into his abdomen.

A
121
Q

Notice when looking at the image, you want both testicles to be in the scrotum. This picture shows where they normally end up. In babies that are diagnosed with cryptorchid, this would be a normal left testicle. About 60% of them are right above the scrotum and you can feel them kind of in the pant line, 25% are in the inguinal canal, and only about 15% of them are actually still in the abdominal cavity.

A

Q

What do “penile vacuum pumps” do?

A

The pump goes over the top of the penis and when squeezed the pump is supposed to reverse the blood flow to the penis. The thought behind penile vacuum pumps is they stimulate blood flow. There is not much evidence that they work.

133
Q

What do “penile implants” do?

A

This device has two cylinders that are medically or surgically placed in the shaft of the penis. One goes on the right side of the urethra, one goes on the left. The pump gets surgically implanted into the testicle. The reservoir, filled with saline, gets implanted into the abdomen, sitting behind the pubic bone. In action, the reservoir fluid will be pumped into the cylinder when somebody wants an erection. To maintain an erection, whatever testicle contains the pump is squeezed and that causes the fluid to be released from the reservoir into the cylinder.

There is no increased blood flow with this pump so a patient can have one of these for as long as they want because there is no cardiovascular compromise.

137
Q

Treatments for inguinal hernias?

A
  1. Surgery

–The intestines are tucked back in and the opening is repaired with a surgical mesh.

– The inguinal ligament goes from the ASIS to the pubic bone on both sides, so even after surgery, a patient can tear another part of that ligament and get another hernia.
