Wang Flashcards
Testicular Masses vs Scrotal masses
Testicular masses: painless, do not transilluminate, malignant
Scrotal masses: painful, transilluminate, benign
Penile anatomy
Corpus cavernosum= erectile tissue
Corpus spongiosum= contains urethra
Tunica Albuginea= CT that surround erectile tissue
Current recommendations regarding circumcision?
Not enough evidence to make it standard procedure
Seminal vesicles?
Continuation of the vas deferens. Contributes 70% of semenal fluids
What hormones are necessary to stimulate spermatogenesis?
LH -> Testicles -> Testosterone + FSH -> spermatogenesis
Leukoplakia of the shlong
Scaly white patches. Need biopsy!
Bowens Disease
Thick, scaly, horny, pinkish brown intraepidermal pre-cancerous lesions
Two types of inflammation of the foreskin
Phimosis- cannot retract foreskin
Paraphimosis- cannot move foreskin foreward
Congenital abnormalities of urethra
Hyposadius- urethra on ventral surface of wang
Episadius- urethra on dorsal surface of wang
Priapism?
Non-erotic, painful sustained erection. Usually self-resolves within a few hours. Unknown etiology.
Peyronie’s disease
Plaque on the corpus cavernosum that causes a curvature in the erection. Sometimes they look like figure eights (jk). Unknown etiology, usually self-resolve.
M/C location for penile cancer?
Glans and foreskin
Ectopic testi location
Testi descends into the perineum, femoral area, inguinal area.
Testicular torsion prognosis?
80% good prognosis if surgically repaired within 6-8 hours of onset. If not taken care of can lead to atrophy and hormonal issues.
Lifting of testi and testicular torsion vs epididymitis
Lifting twisticle causes increase in pain
Lifting testi with epididymitis decreases pain
Hydrocele definition and age range
Fluid in sheath that surround testicles. Often painless and will transluminate. M/C in older men.
Varicocele- definition and age range
Blood backs up in the spermatic veins d/t faulty venous valves. Does not transilluminate. M/C younger men. Treatment is usually just supporting the testis.
Causes of orchitis
Bacterial infection or mumps virus. Can lead to atrophy and decreased hormone production.
What is the m/c cancer in males 15-35? Dx test? Tx?
Testicular cancer. Dx with US, usually also take Chx x-ray and abdominal CT. Treatment is orchectomy with surrounding lymph nodes.
Size of the average prostate?
4cm
Two types of prostatitis and their subtypes if there are any? Associated microorganisms and Dx tests
Acute bacterial prostatitis- usually E. Coli
Chronic Prostatitis: Bacterial (ureaplsma urealyticum). Non-bacterial (unknown etiology)
PSA levels, WBC in urine, ^ pH of prostatic fluid.
Prostadynia?
Prostatitis symptoms without infection or inflammation. Finesteride (BPH med) may help. May be d/t MSK spasm or nerve entrapment.
Pudendal nerve entrapment. Locations of entrapment?
Dx of exclusion.
- B/t sacrospinous and sacrotuberous ligs
- B/t falciform ligament of sacrotuberous lig
- In obturator fascia
Etiology of BPH. Who is at risk? Findings on DRE?
Decrease testosterone with increase estorogen and increased sensitivity of prostate to DHT causes BPH.
African American men high risk.
Soft and boggy DRE.
Does BPH increase risk of cancer?
No
At what age should you start DRE?
50
What produces PSA?
Prostate capsule and periurethral glands
What PSA values indicate you shoulder refer your patient?
4-10 ng/mL with abnormal DRE
>10 ng/mL
