Ultrasound (if unclear, CT scan)
What is the criteria regarding number of cysts on each kidney, diagnosing polycystic kidney disease?
age < 60: 2+ cysts on each kidney
age > 60: 4+ cysts on each kidney
hematuria that is persistent and recurring in someone with polycystic kidney disease suggests what?
renal cell carcinoma
Patient with polycystic kidney disease endorses flank pain + fever + leukocytosis. What do you suspect?

Medullary Sponge Kidney
What area of the kidney is affected in medullary sponge kidney?

you’ll see a “swiss cheese appearance” on imaging of this disorder
medullary sponge kidney
can you transplant a non-PKD kidney to a PKD patient with success?
YES - they will NOT develop PKD
what does gross hematuria in PKD patient typically represent?
rupture of a cyst into the renal pelvis (resolves within 7 days)
in a patient with suspected renal infection, you get a UA. It is normal, but you can’t rule out infection…why?
UA may be normal because cyst may not communicate with the urinary tract
True or false: 50% patients with PKD present with hypertension, but it will develop in most patients at some point in the course of the disease anyways.
TRUE
True or false: aggressive BP control seems to help slow the decline in GFR with a patient who has PKD
false - it does not stop the decline in GFR
this common, BENIGN disorder is present at birth and diagnosed at age 40-50

hematuria recurrent UTI nephrolithiasis nephrocalcinosis tubular acidosis
Diagnosing medullary sponge kidney? (what is seen on this imaging?)
CT - cystic dilation of distal collecting tubule, striated appearance, calcifications i collecting duct
medullary sponge treatment?
none - keep hydrated, add thiazide diuretics to decrease calcium excretion
