Flashcards in Male Genital System Deck (14):
1

Abnormal location of urethra orifice

Hyposapdia (ventral)
-Most common
Epispadia (dorsal)
-Rare

2

Other genital abnormalities associated with hypospadias and epispadias

Inguinal hernias
Undescended testes

3

Clinical consequences of hyposapadias and epispadias

Constriction of orifice
Urinary tract obstruction
UTI
Impaired reproductive function

4

Phimosis

Prepuce cannot easily be retracted over the glans
May be congenital
Usually acquired from balanosposthitis and scarring of prepuce
Distal penile inflammation

5

Parphimosis

Stenotic prepuce traps the glans
Urethral constriction

6

Candidiasis

Common in diabetics
Erosive
Painful
Pruritic
Can involve entire genitalia

7

Balanitis (balanoposthitis)

Inflammation of the glans (plus prepuce)
Associated with poor local hygience in uncircumcised men
Irritant-smegma
Infection- multiple bacterial or fungal origins
Incidence: 3% of uncircumcised males
Distal penis is red, swollen, tender
Purulent d/c may be present

8

Cryporchidism

Failure of testicular descent into the scrotum
Right > left

9

Pathogenesis of cryporchidism

Hormonal abnormalities
Testicular abnormalities
Mechanical problems

10

Clinical course of crytorchidism and testicular atrophy

Bilateral: tubular atrophy and sterility
Unilateral: tubular atrophy may also occur in the contralateral descended testis
Risk of malignancy increased 3-5 times in cryptorchid testis
Orchiopexy reduces the risk of sterility and cancer

11

Other causes of testicular atrophy

Chronic ischemia
Inflammation or trauma
Hypopituitarism
Excess female sex hormones
Malnutrition
Irradiation
Chemo

12

Mumps

Orchitis in 20% of adult males with mumps
Edema and congestion
Chronic inflammatory infiltrate
May cause atrophy and sterility

13

Tuberculosis

Granulomatous inflammation
Caseous necrosis

14

Autoimmune granulomatous orchitis

Rare finding in middle aged men
