Priapism
considered an emergency because can result in ischemia/necrosis
Causes:
Idiopathic: usually from prolonged sexual excitement
Secondary: assoc with sickle cell dz, DM, CML, penile trauma, drugs, alcohol, cocaine, black widow spider bite

Painless scrotal masses/Swellings
tumors, abscess, hematocele (blood filled, does not transilluminate), hydrocele (serous fluid filled, transilluminates), varicocele, sebaceous cysts, scrotal edema, indirect inguinal hernia, spermatocele
31
condition that has a “bag of worms” appearance, located along spermatic cord (80% on left)
worsens with valsalva maneuver and with standing
Varicocele
Non-tender, may have “dragging” sensation
Development of a new varicocele or worsening of an old one in an older man:
a. On L: may be a tumor or other mass occluding the L renal or testicular vs.
b. On R: occlusion of the vena cava possible.
Possible sequellae: infertility from dec spermatogenesis (inc scrotal temp)
Diagnosis – angiography
32

epididymitis, testicular torsion, testicular trauma, mumps orchitis
33
testicular torsion
Emergency--assume until proven otherwise! Needs to be de-torsed <6hrs!
Severe scrotal pain after an episode of trauma or during intensive exercise; or spontaneous in sleep. Common age range 10-25 yo
34
ssx for testicular torsion
Sudden, acute onset unilateral, constant pain, poss N&V
Swollen, tender, erythematous scrotum: difficult to discern structures
Affected testicle higher, epididymis may be anterior; reactive hydrocele possible
Pain may radiate to the abdomen “acute abdomen”
Elevation of the scrotum does not relieve pain (negative Prehn’s sign)
Cremasteric reflex absent
Dx: doppler US
35
spermatocele
small, painless cyst on the superior posterior pole of the testicle
benign
36
cause of acute epididymitis
Infectious: result of an ascending LUT infection (from UTI or STI)
Non-infectious: urine reflux/chemical irritation into ejaculatory ducts from heavy lifting or local trauma
37
acute epididymitis
SSX
PE
DX
SSX:
Painful, swollen epididymis; pain may radiate along spermatic cord to abdomen
Hydrocele may develop
Overlying skin may look like peau d’orange; skin is movable (fixed suggests abscess)
May be febrile.
Discharge (if ascending infection), urinary frequency, dysuria may be present
Toxic appearance if sepsis from widespread bacterial infection (rare)
Sequelae: chronic epididymitis
PE:
exquisitely tender, swollen epididymis
Scrotum often indurated, erythematous
elevating the testicle eases pain (positive Prehn’s sign)
no change in cremaster reflex
DX:
UA reveals pyuria
Urine culture, NAAT (Nucleic Acid Amplification Test) testing for GC/chlamydia
Scrotal ultrasound to rule out torsion in those <30
38
cause of chronic epididymitis
inflammation with no infection present
39
with chronic epididymitis PE reveals
enlarged, thickened, non-tender epididymis
40
what is the name of the condition where the testes fail to descend into the scrotum during infancy?
cryptorchidism
there are several types:
a. true cryptorchidism - testis remains in abd. cavity from mechanical obstruction or hormonal abnormality
b. incomplete – testis in inguinal canal, obstructed by mechanical means
c. ectopic testis - lies outside the usual course of descent
d. hypermobile or retractile testis - may lie in the scrotum at times (e.g. hot bath) and then retract up into the inguinal canal
PE: palpate the testicles, if unpalpable, have pt squat or valsalva and repeat palpation
41
with cryptorchidism there is a risk of developing which two conditions later in life?
infertility
| testicular cancer
42
what is the most common solid cancer in males 15-34 yo?
testicular cancer
43
what are the two types of testicular cancer and from where do they originate?
Seminomas (40%) - arising in seminiferous tubules)
| Non-seminoma germ cell tumor - Embryonal (24%), Teratoma (5%), mixed (26%)
44
What are the SSX of testicular cancer?
painless testicular nodule, usually smooth enlargement, firm and non-tender, increases in size over time, may get dull ache, sensation of heaviness/weight, mass does not transilluminate (bc solid tumor)
45
What is the appropriate work-up for testicular cancer?
Scrotal US, Pelvic CT (esp if have concerns its METS)
| 5 yr survival of seminoma is > 80% with tx
46
what portion of the prostate is palpable? what is the normal size and consistency of the prostate?
portion of the prostate that is palpable is the peripheral zone, the transition zone is not palpable
normal size of the prostate is 4 cm in length and width
normal consistency is tip of nose
47
what are abnormal consistencies for the prostate and what are their corresponding conditions?
rubbery- BPH
boggy - congested
indurated - nodules
hard - consider tumor in absence of WBCs & infxn
48
labs to consider for prostate problems?
serum prostate-specific antigen (PSA)
serum PSA levels increase if the barrier between the epithelium and the bloodstream is damaged (barrier damaged due to cancer, bacterial infxn, and infarction)
Draw serum PSA before doing a DRE and obviously before prostate bx
Using PSA as a reliable screen for prostate cancer is currently under great scrutiny.
Other measures:
a) PSA velocity (how quickly it is elevating)
b) Free/bound PSA ratio (less amts of free with cancer)
49
can you think of any reasons for the rise in PSA levels?
```
DRE (do blood draw before!)
Ejaculation, recent sexual activity
BPH
Prostate cancer
Cystitis
Acute & Chronic prostatitis
Prostate bx
exercise involving perineal pressure (biking)
```
50
can you think of any reasons for the fall in PSA levels?
```
Finasteride
Saw palmetto
Radical prostatectomy
Withdrawal from anti-androgen drugs
Regular prostatic massage
Green tea
```
51
What is occurring physiologically with benign prostatic hyperplasia (BPH)?
hyperplasia of cells within the transition zone, resulting in formation of large, fairly discrete nodules in the periurethral region. The lumen of prostatic urethra narrows leading to urine outflow obstruction.
52
what is the incidence of BPH?
Increases with age, at age 40 there is a 8% chance and by age 80 there is an 80% likelihood of developing it
53
what are the SSX of BPH?
progressive urinary frequency, urgency, nocturia due to incomplete emptying and rapid filling of bladder, hesitancy, intermittency of urinatioin, decreased force of stream (forked stream)
54
What are the possible complications of BPH?
UTI from urine stasis
Urolithiasis from urine stasis
Straining to urinate may cause rupture of veins, hemorrhoids and hernias to name a few
55
What PE should be completed for BPH? What are the anticipated findings?
DRE: enlarged rubbery consistency
| Abdominal exam: possible distended bladder
56
Which labs should be ordered for suspected BPH?
BUN (incrs)
UA and urine culture (to r/o causative or concomitant infxn)
PSA (mod. incrs)
57
Procedures for BPH?
Uroflowmetry (to check urine flow rate and post-void residual volume)
TRUS or prostate bx (to r/o cancer)
58
What condition can coexist with BPH?
Prostate cancer
59
