What is cryptorchidism?
undescended or maldescended testis
What are the risk factors of cryptorchidism?
prematurity, low birth weight, small gestational size, twinning, maternal exposure to estrogen during 1st trimester, family history
What system must be intact for normal descent of the testicles?
normal hypothalamic-pituitary-gonadal axis
What hormones facilitates descent of the testicles?
testosterone and dihydrotestosterone
What are the mechanical causes of cryptorchidism?
gubernaculum not firmly attached to scrotum and the testis don’t descend, also associated w/ short spermatic artery, poor blood supply
What are the 3 types of palpable undescended testicles?
true undescended, ectopic, and retractile
Where are the majority of true undescended testicles?
inguinal canal
What type of palpable cryptorchidism correctly exit the external inguinal ring but are then misdirected from the normal descent?
ectopic
Which type of palpable cryptorchidism is mostly inguinal location, due to an active cremasteric reflex, and must be monitored regularly as risk of ascent approaches 50%?
retractile
What are the 3 types of nonpalpable cryptorchidisms?
intra-abdominal, congenital anorchia, vanishing testes
Which type of cryptorchidism is usually w/in a few cm of the inguinal ring?
intra-abdominal
Which type of cryptorchidism is absence of one or both testes?
congenital anorchia
Which type of cryptoorchidism is thought to be due to intrauterine or perinatal vascular event?
vanishing testes
How are unilateral undescended testis w/out hypospadias diagnosed?
physical exam
What extra test are required for undescended testes w/ hypospadias or bilateral nonpalpable testes?
testosterone, 17-hydroxylase progesterone, LH, FSH, HCG injection test, and diagnostic laparoscopy to locate nonpalpable testicle
At what age is the recommended treatment of cryptorchidism?
6 months
What is the medical tx for cryptorchidism?
HCG injections
What do HCG injections do?
stimulate leydig cells to produce androgens
What are adverse effects of HCG injections?
secondary sex characteristics
What is the surgical tx for cryptorchidism?
orchiopexy between 6 to 12 months
Orchiopexy must be considered for what types of cryptorchidism?
abdominally located & for atrophic testicles
Cryptorchidism mostly causes what type of testicular cancer?
seminoma
What is the inability to achieve or maintain an erection sufficient for sexual intercourse?
erectile dysfunction or formally known as impotence
What are the risk factors for erectile dysfunction?
HTN, vascular disease, smoking, diabetes, drugs, hormone disorders, spinal cord or brain injuries, pelvic trauma, venous leak, peyronie’s disease, psych disorders
What accounts for 50 to 60% of impotence in men over 60?
arteriosclerosis (vascular disease)
What drugs cause erectile dysfunction?
sympathetic blockers, thiazide diuretics, antidepressants, ketoconazole, cimetidine, alcohol, tobacco, recreational drugs
What hormone disorders cause erectile dysfunction?
testosterone deficiency, excess prolactin, hypothyroidism
What condition is an inflammatory disease causing scarring of erectile tissue, produces curvature of the penis interfering w/ sexual function and causing a painful erection?
peyronie’s disease
What psychological conditions cause erectile dysfunction?
anxiety, psychogenic impotence, performance anxiety, depression, and interpersonal conflicts w/ partner
What should be examined for erectile dysfunction?
peripheral vascular exam, lower extremity musculoskeletal , neurological, genitalia, prostate, breast, and visual fields
What test involves injecting prostaglandins that will induce erections in men w/ intact vasculature, and after penile pressure is measured and images taken after injections?
vasoactive injection
What test evaluates blood flow, venous leak, signs of arteriosclerosis, measures penile pressure?
duplex ultrasound
What test documents erections during sleep?
nocturnal penile tumescence (NPT)
Intact erections during sleep is suggestive of what cause of erectile dysfunction?
psychogenic cause
Absence of nocturnal erections may indicate what types of erectile dysfunction?
impaired nerve function or blood supply
What test involves electromagnetic vibrations evaluating sensitivity and nerve function?
penile biothesiometry
What's a contrast study that assesses for both arterial insufficiency and venous leakage in erectile dysfunction?
cavernosography
What type of drugs are used to tx erectile dysfunction?
selective phosphodiesterase type 5 inhibitors
What are 3 selective phosphodiesterase type 5 inhibitors?
sildenafil, vardenafil, tadalafil
What is the MOA of selective phosphodiesterase type 5 inhibitors?
increase levels of guanosine monophosphate (cGMP), which are smooth muscle relaxers
When are selective phosphodiesterase type 5 inhibitors contraindicated?
w/ nitrates which cause exaggerated cardiac preload reduction & hypotension
What is used as a self injection into the penis for erectile dysfunction?
prostaglandin
What are the effects of prostaglandin injections?
vascular dilation and relaxation of smooth muscle, repeated injections may cause penile scarring, priapism
What are prostaglandin pellets inserted into the urethra used to tx erectile dysfunction?
intraurethral suppositories
What is used to create a manual creation of an erection and works best in men who achieve partial erections?
vacuum devices
What is a surgical insertion of malleable or inflatable rods or tubes into the penis?
penile implants
What is used to tx androgen deficiency in erectile dysfunction?
testosterone injections or patches
