heme, sickle cell anemia, leukemia, thalassemia, MM, TTP
Neuro (spinal shock)
tumors (mets)
perineal, penile trauma
Iatrogenic (injections - up to 25%, MC cause in adults)
drugs: antiHTN, antidepressants, anticoag, alpha blockers, cocaine)
Infection: malaria, spider toxins
metabolic disorders: gout, hemodialysis, high lipid content, TPN, diabetes, amyloidosis

27
Q

Hx and PE findings of a priapism?

A
  • hx:
    presence of pain, duration, role of antecedent factors, prior episodes. Existence of etiological conditions and erectile fxn status
  • PE:
    -insepction and palpation of penis may indicate the extent and tumescence and presence and extent of tenderness
    -abdominal, perineal, and rectal exams can reveal signs of trauma or malignancy
28
Q

Dx of priapism?

A
  • CBC
  • can use color duplex doppler US to dist. ischemic from nonischemic
  • aspiration of blood from corpus cavernous can be eval:
    if darkly colored (unoxygenated) - ischemic
    if bright red (oxygenated) - nonischemic
    -can do ABGs on aspirated blood
29
Q

Tx of priapism?

A
  • pain management, urgent urological consultation
  • ischemic:
    evacuation of blood then intracavernous injection of alpha-adrenergic sympathomimetic agent- phenylephrine (penile shaft block can be done first)
    -90% of men w/ ischemic priapism lasting more than 24 hrs don’t regain ability to have sexual intercourse
  • nonischemic:
    initially - observe, 62% spontaneously resolve, urological consult for further management as other tx can cause ED
30
Q

Causes of penile fx?

A
  • tx: surgical correction
  • complications:
    ED
    penile curvature
    pain
33
Q

When does paraphimosis occur?

A
  • occurs when foreskin in uncircumcised or partially circumcised male is retracted behind glans penis, develops venous and lymphatic congestion and can’t be returned to its normal position - this is a UROLOGIC EMERGENCY
34
Q

Hx and Physical findings of paraphimosis?

A

hx:
swelling of penis and penile pain, cause of irritability in preverbal infant, recent penile exam, foley insertion, cystoscopy

physical findings:
ensure that there is no constricting fb, edema and tenderness of glans, painful swollen retracted foreskin, penile shaft is unaffected, w/ ischemia the color of glans will change from normal pink to blue or black and will be firm rather than soft

35
Q

A

lab:
UA
- pyuria can be seen w/ UTI, chlamydia and gonococcal urethritis
- hematuria + pyuria rules out STI
- hematuria alone w/o sxs and signs of urithrolithiasis may be due to cancer and pt should have further f/u
- urine culture recommended in men w/ pyelonephritis or women w/ complicated UTI

  • abdominal plain films (uric acid won’t show)
  • usually non-contrast helical CT
  • US in pts who need to avoid radiation
49
Q

Tx of nephrolithiasis?

  • 85% of testicular injuries are result of blunt trauma
52
Q

Initial management of GU trauma?

A
  • focus on rapid ID and stabilization of life threatening injuries
  • rarely life threatening although shattered kidney or major renal vascular laceration can pose a threat to life or to kidney itself
  • once pt is stabilized eval for GU injury is undertaken
53
Q

secondary survey for GU trauma?

A
  • inspect perineum and external genitalia
  • look for blood in underwear
  • look in folds of buttocks for perineal lacerations which may indicate a pelvic fx
  • rectal exam:
    sphincter tone
    presence of blood
    position of prostate
  • riding high or boggy: disruption of membranous urethra
54
Q

MC site of urethral injury?

A
