Q

treatment of hydrocele

A
  • observation, especially in infants

Q

varicocele

A

dilations of the papiniform plexus.
papiniform plexus on the right drains into the internal spermatic vein and then into the IVC; on the left it drains into the renal vein and has a more acute angle. therefore the left is affected 100% of the time and right sided should be further investigated
-may affect fertility

22
Q

testicular malignancy epidemiology

A

peak incidence between 20-40 yrs
accompanying epididymitis may delay dx
solid tumors don’t transiluminate
most commonly germ cell tumors

23
Q

carcinoma arises:

A

from epithelial cells which cover the body or line organs

24
Q

sarcoma arises:

A

from connective tissues and are often named for the specific type of tissue

25
Q

testicular malignancy imaging

A

abdominal and pelvic ct to evaluate retroperitoneal lymph nodes

26
Q

treatment of testicular malignancy

A

external beam radiation, surgery: radical orchiectomy; lymphatics drain into the inguinal nodes [stage dependent]

27
Q

prostatitis

A

inflammation of the prostate; classified as acute bacterial prostatitis, chronic bacterial prostatitis, non-bacterial prostatitis (inflammatory), prostadynia.

28
Q

acute bacterial prostatitis

A

recovery of bacteria from prostatic fluid, purulence of fluid, and systemic signs of infection

29
Q

chronic bacterial prostatitis

A

recovery of bacteria in significant numbers from prostatic fluid in the absence of concomitant urinary infection or significant systemic signs (as in acute bacterial prostatitis)

30
Q

nonbacterial prostatitis

A

no recovery of significant numbers of bacteria from prostatic fluid, but the fluid consistently reveals microscopic purulence

31
Q

prostadynia

A

no recovery of significant bacteria or purulence in prostatic fluid, but patients have persistent urinary urgency, dysuria, poor urinary flow, and prostatic discomfort

32
Q

benign prostatic hyperplasia (BPH)

A

hyperplasia of the prostatic epithelium; it is defined histologically.

33
Q

Symptoms of BPH

A

irritative voiding symptoms (dysuria, nocturia, urgency, frequency) and symptoms of bladder outlet obstruction (intermittency, weak stream, post-void dribbling) may lead to acute urinary retention

34
Q

what to check to dx BPH

A

PSA elevated

DRE may show an enlarged gland

35
Q

treatment of BPH

A
5 a-reductase inhibitors (finasteride)
alpha blockers
saw palmetto
transurethral microwave thermotherapy
transurethral resection
36
Q

prostate cancer

A
rare before age 50
dre recommended annually after age 40 
PSA after age 50? 
-95% are adenocarcinomas
-most common mets are to the pelvic lymph nodes and skeleton; visceral mets occur late and are less common
37
Q

urethritis

A
  • gonococcal and non gonococcal
  • NGU think chlamydia
  • caffeine
  • spermatocides, lotions, soaps, condoms
38
Q

non-gonococcal urethritis (NGU) defined by:

A

urethral discharge or dysuria and urethral inflammation documented by mucopurulent discharge or leukocytes on gram stain

39
Q

symptoms of NGU

A

mucoid or watery discharge common
dysuria common
42% asymptomatic

40
Q

urethritis treatment

A

appropriate eval and antibiotic treatment (azithro or doxy)
consider trial of metronidazole if symptoms persist (trichamonas)
decrease caffeine
avoid irritants

41
Q

balanitis

A

inflammation of the glans penis. usually occurs in conjunction with posthitis (inflammation of the prepuce) and can be associated with poor hygeine

42
Q

symptoms of balanitis

A

smegma (glandular secretions), sloughed cells, and mycobacterium smegmatis may collect under the foreskin and cause direct irritation or infection

43
Q

phimosis

A

too tight foreskin to retract; hygeine issues; sexual function issues

44
Q

paraphimosis

A

too tight to get back to starting point (foreskin) may need emergent circumcision if tourniquet effect cannot be reversed manually

45
Q

penile cancer

A

risk factors: hpv infection, smoking, treatment of penile psoriatic lesions with psoralen and uv exposure
usually squamous cell carcinoma
often presents with leukoplakia
often have a significant morbidity and mortality

46
Q

types of ED

A

failure to initiate (endocrin, psychogenic, neurogenic)
failure to fill (arteriogenic)
failure to store (venoocclusive dysfunction)
DM atherosclerosis, drugs are about 80% of ED

47
Q

vasculogenic ED

A

unrestricted outflow may occur with increased adrenergic activity or decreased parasympathetic tone to the affected area. decreased compressability of the tunical veins

48
Q

neurogenic ED

A

spinal cord lesions (lower cord lesions produce higher degree of dysfunction)
multiple sclerosis
peripheral neuropathy
pelvic surgery

49
Q

endocrinologic ED

A
testosterone levels are probably a factor (augmentation is not helpful if levels are normal)
prolactin excess can depress libido and testosterone
estrogen excess (excess fat)
50
Q

diabetic ED

A

primarily secondary to vascular and neurologic complications of DM. decreased levels of nitric oxide sythase in neural and endothelial tissues

51
Q

psychogenic ED

A

performance anxiety, loss of attraction, relationship conflict, depression, sexual inhibition, fear of STD, pregnancy, commitment. Excess sympathetic tone; blocking of sacral cord reflexogenic activation of the vascular changes in the penis necessary for erection

52
Q

medication related ED

A
diuretics
antihtn
hormones
antidepressants
H2 blockers
ETOH, cocaine, THC
others
53
Q

ED evaluation

A

history, evidence of vascular disease, evidence of hypogonadism, penile palpation (plaques in corpora), lab exam: prolactin, testosterone, complete metabolic profile, CBC, lipids
