Genitourinary Flashcards
What controls the bladder neck? What controls the bladder?
Bladder neck: Under adrenergic control
Bladder: Under cholinergic control
What are the treatment options for BPH?
Alpha blockers: Terazosin, tamsulosin
- SE: Hypotension, dizziness, asthenia
5 alpha reductase inhibitors
Gold standard for relieving bladder outlet obstruction: Transurethral resection of the prostate (TURP)
What male genital problem causes an increased risk of testicular cancer?
Cryptorchidism (40 times as likely to develop testicular CA)
(Most common genital problem encountered in pediatrics)
Also increases risk of testicular torsion and infertility
What is Cryptorchidism? what side is it most common?
Incomplete descent of the testes into the scrotum during fetal development
More common on the Right side
How do you test for functioning testicular tissue?
Hormonal challenge: HCG will confirm the presence of functioning testicular tissue (hcg is virtually identical to Pituitary LH)
If the FSH is 3X normall and no increase in testosterone in response to hCG, functional tests are not present
How do you treat Cryptorchidism?
Most will spontaneously descend by 3 months
Treat at 6 months
- hcG-identical to pituitary LH
- Agonist analogs of GnRH-Stimulate the release of LH and FSH
What is Prehn’s sign?
Elevation of the testicle–>
- Relieves pain in epidydimitis (positive prehn)
- No relief of pain in torsion
What are the symptoms and signs of Fournier’s Gangrene? Risk Factor?
RF: Indwelling catheter
Sxs: Fever, toxicity, sepsis
PE: scrotum reveals eschar, brawny, violaceous, bullous edema with a cellulitis extending into abdominal wall an perineum
Surgical Emergency!!
What is the most common type of bladder cancer? How does it present? RF? Diagnostics?
Transitional Cell carcinoma
Presents with gross hematuria
- If you see gross hematuria–>need a cystocopy and biopsy
RF: aniline dyes, smoking
Schistasomiasis–associated with Squamous cell
What is the most common renal malignancy? who does it most commonly affect? How is it diagnosed?
Renal cell carcinoma
Black men who smoke
Dx: CT scan
CXR (to exclude pulmonary metastasis)
What is the classic triad of Renal cell carcinoma? How do you treat it?
- Hematuria
- mass
- flank pain
Tx: Nephrectomy (if early), Radiation (if late, bad prognosis)
What medications can cause urinary retention in men?
Anticholinergics, OTC cold meds, Opiates, benzos, and general anesthesia
“I had surgery yesterday and now I can’t pee”
How do you treat acute urinary retention? What do you have to warn the patient about?
Alpha blockers : warn them that it may cause orthostatic hypotension
What controls Erection? What controls ejaculation?
- Erection requires intact parasympathetic
- also somatic nerve supply, unobstructed arterial flow, adequate venous constriction, hormonal stimulation, pyschological)
- ejaculation=sympathetic
“Point & Shoot”–>P=parasympathetic, S=sympathetic
What is Priapism?
Painful condition in which erect penis does not return to flaccid state.
What is the most common drug related cause of Priapism? What is the most common etiology in most emergency departments (and in boys)? Tx?
Trazadone most common drug related cause (hippa)
also Sildenafil (viagra)
Sickle cell disease-common cause in most ER
Dont miss leukemia in kids!
Tx: Phenylephrine
How does testicular cancer present? How do you diagnose?
Most common neoplasm in men 20-35 y/o
S/S: Painless unilateral mass (that cannot be separated from the testicle); Lung mets may be first symptom
Dx: UTZ for diagnosis, CT for staging
Testicular Torsion: S/S, Who?, Dx? Tx?
12-18 y/o; Testical is abnormally twisted on its spermatic cord–compromising arterial supply and venous drainage of testicles leading to testicular ischemia
PE: abnormal lie (high-lying painful testes), abnormal cremasteric reflex (neg. Prehn’s sign),
ass. with bell clapper deformity (Inadequate fixation of testes within the scrotum
Dx: If you think it’s torsion, immediately get US! US will show ischemia with abnormal flow
IF no access to urology attempt manual de-torsion with open book
Tx: SURGICAL EMERGENCY! Detorsion and ocrhiopexy
What is Balanitis/Balanoposthitis? What causes it?
Redness of the foreskin and penis with foul smelling discharge
Associated with lack of hygeine, usually found in uncircumscribed young boys
ORchitis: What is it? who does it most commonly affect? S/S?
- Commonly caused by ascending bacterial infection from Urinary tract.
- Occurs in 23% of postpubertal males who have mumps infection
(Typically follows Parotitis within 8 days)
- Sx: unilateral testicular swelling and tenderness
- Fever, tachycardia
Epididymitis: What is it? WHat organisms are involved?
- Infection of the epididymis acquired by retrograde spread of organisms through the vas deferens
- <35 y/o: Chlamydia and gonococci
- >35 y/: E. coli
- PE: warm tender erythematous enlarged scrotal mass
- Positive Prehn’s sign
Tx: <35 y/o: Ceftriaxone 250 mg IM + doxycycline 100 mg BID 10 days
> 35 y/o: Ciprofloxacine 500 mg BID PO x 10-14 days
What is Phimosis?
The inability to retract the foreskin over the glans penis
“Turtleneck tooo small to put over your head
circumcision may be a tx
What is Paraphimosis
entrapment of the foreksin behind the glans penis
“So now turtleneck is not only too small to put over your head, but its not strangling your gland)
EMERGENCY! may end up in edema or gangrene
What is a varicocele? What are the symptoms? Dx?
Formation of a venous varicosity within the spermatic vein (Paminiform plexus)
Left vein > Right vein
PE: Chronic, nontender mass that does not transilluminate
“Bag of worms”, increases in size with valsalva
Dx: Doppler Sonography
PE findings of hydrocele? of Spermatocele?
hydrocele: Soft, transluminating nontender mass
Spermatocele: Painless cystc mass containing sperm; Palpable, round firm cystic mass free floating above the testicle, which transilluminates; may be tender
Dx: Clinically
Name prerenal etiologies of acute renal failure and Labs
Decreased renal perfusion secondary to
- Hypovolemia
- hypotension
- CHF
Labs: Urine Na <20 mEq/L (The integrity of kidneys remain intact, So sodium is conserved as GFR declines in an attempt to reestablish volume and perfusion, resulting in a fractional excretion of sodium, FENa <1).
Name Post-renal etiologies of acute renal failure
Tubular obstruction, Obstructive uropathy, nephrolithiasis, BPH
Name intrinsic renal etiologies of acute renal failure; labs
- ATN
- Nephrotoxins
- Interstitial disease
- glomerulonephritis
- vascular disease
Labs: Increased urine Na > 40 mEq/L (when glomeruli are injured, the kidneys lose the ability to reabsorb sodium as the GFR decreases; FENa >1
Decreased BUN: Cr ratio
What are the symptoms of glomerulonephritis? What is seen on labs?
Sxs: Hematuria, tea/coloa-colored urine, oliguria, edema of face/eyes (classic, worse in AM), HTN
UA: Mishaped RBCs due to passage through glomeruli, RBC cast
+ antistreptolysin O if recent strep infection
Tx: depens on etiology, Steroids, immunosuppressive drugs
Defn of Nephrotic syndrome
>3.5 g of protein in 24 hours
