Chronic renal failure - coag and platelet findings?
Normal INR, Normal PT/pTT
Normal plt count but INC BT. Tx DDAVP (INc F8)
Rental tubular acidosis acid base status and lab finding?
Who is at risk?
Metabolic acidosis w/ normal anion gap .
Preserved kidney function - May see HyperK (especially in poorly controlled DM)
In void cycle
intiial hematuria
vs
terminal hematuria
Vs
TOTAL hematuria
Initial - urethral damage
Terminal - bladder/prostate - may see clots as well
Total - kidney, ureter damage
Best way to prevent UTI when cathing?
Intermittent cath > antibacterial wash
Single renal cyst found - ax - what now?
How to know it is a simple cyst?
Simple cyst - thin wall, no solid parts, not loculated.
asx - reassurance and observe
Interstitial cystitis presentation, UA findings, tx?
INC frequency, dyspareunia, RELIEF WITH VOIDING (aka the irritable bowel of pee), NORMAL UA!!
Tx amitriptaline, analgeics. Found in women, psych comorbid
RCC - originates from? histo findings? Gross findings>?
presentation (3 factors)
RCC - proximal
Histo - Clear cell
Grossly - Yellow Mass
Findings: Hematuria> Mass> Flank pain
AGE AND PRESENTATIOn
Neuroblastoma
Wilms?
NB - 1 - poorly circumsribed, crosses midline, HVA INC
WIlms - 2-5y.o - midlinem, smooth, WAGR, Beckwith Wiederman
Renal oncocytoma - gross and histo?
Central scar. Large Eos cell.
Transitional CA -
Lower tract, field defect. Smoking, Rubber.
Squamous CCA - - origins, etiology
Chronic irritation, smoking, schistosoma
Angiomyolipoma - seen in whom? risk?
Tuberous sclerosis kids, hamartoma (benign )
Adeno CA in UG tract?
Urachal remnant -Associated w/ extrophy
Thiazide - complications x 4
Hyper
Glycemia
Lipidemia
Uricemia
Calcium
Uncomplicated cystitis - workup and tx?
Tx W/O CULTURE.
Culture if tx fails once.
bactri, Nitrofurantoine, Quinolone
Rhabdomyolysis renal workup findings?
Blood on UA, NONE on sed microscopy
Pedi UTI - What to do?
2mo-2y. Bladder, renal US.
recurrent UTI -> voidiing cystourethrogram
AD PKD - presentation?
associations?
Mass, hematuria, HTN
hepatic cyst, divertulosis, berry aneurysm, abd, inguinal hernia
Renal osteodystrophy findign
After ESRD, DEC GFR leads to phosphate retention. See INC P, with DEC Ca, with INC PTH. Similar to Pseudohypoparathyroidism.
Overflow incontinence – presentatio
full bladder w/ frequent low volume leaks in DM
Overflow incontince pharm tx vs Urge incontinence?
Overflow - Cholinergic agonists (Bethanechol) vs Urge – Anticholinergic (oxybutynin)
Urge Incontinence– Initial tx
– conservative – “bladder training” with frequent scheduled voiding.
Multiple myeloma kidney damage due to which spot on nephron?
– Renal tubular > Glomerular (amyloidoisisi )
MOST EFFECTIVE means of DEC DM nephropathy
blood pressure control. Not glucose control.
SIADH urine findings - osm and Urine Na?
has HIGH URINE SODIUM with High Urin osmolality!
Tx of Myoglobinuria
Salien
Mannitol
Bicarb
Myoglobin is a toixin - mannitol allows INC urine flow rates taht DEC contact time between tubular cells and myoglobin.
Lab values of hepatorenal are consitent w?
Prerenal azotemia
Most accurate test for AIN?
Hansel /Wright Stain - detects Eos!
UA cannot detect Eos
WHich stones get Lithotripsy?
0.5 to 2~cm.
Later than 2cm may need surgery.
Anticoagulation in pt w/ renal insufficiency (GFR less than 30)
MUST GIVE UNFRACTIONATED HEPARIN – Cannot give LMWH, fondaparainux, and rivaroxaban to pt w/ renal problems. Bridge to Warfarin.
Posterior urethral injury
high riding prostate, inability to urinate. Scrotal hematoma
Fatty cats? Broad/waxy casts?
Fatty – Neprhotic. Broad/waxy = Chronic renal failure
Immedaite and long term treatemetn of uric stones?
Potassium Citrate (alka) helps prevent recurrent stones.
Imaging modality for uric acid stone –
radiolucent – cant be seen on Xray, but CT noncom can see them
Varicocele think?
RCC
Renal artery stenosis in fibromuscular dysplasia tx
– Angioplasty with stent> ACE/medical therapy
Crystalline nephropathy (acyclovir) dmg via?
Rental tubular obstruction
Hyposthenuria –
found I pt with sickle cell disease – inability to concentrate urine. Frequent nocturia. Sickle cells sickle in vasa rectae and impair countercurrent exchange.
Vesicoureteral reflux vs posterior urethral valves?
Vesicoureteral reflux -> scarring. Posterior urethral valves – most common cause of chronic renal failure in children.
Pyelo meds
Cipro, Amp+Gent. Bactrim and Nitrofurantoin are for UNCOMPLICATED CYSTITIS. Complicated -> Cipro as well.
Massive hematuria that resolves, with UA sig only for blood
- Renal papillary necrosis – extraglomerular, often resolves spontaneously. Other problems in Ss patients – inability to concentrate urine in tubes.
Infective endocarditis in IVDU w/ DIASTOLIC MUMUR with 2:1 AV block
– Aortiv valve endocarditis w/ with perivalvular abscess. Tricuspid regurg would be SYSTOLIC!
Urethral stone ith onset of high fever and INC pain
immediate abx and percutaneous stent
