UROLOGY Flashcards
How are kidneys related to bones?
- Regulate levels of calcium, phosphorus, PTH, and vitamin D
- Activate vitamin D
What is creatinine?
Waste product of protein breakdown
What is the term for a test performed to analyze changes in cellular structure related to malignancy?
Urine cytology
What is the term for an invasive test where contrast is instilled into the bladder via cystoscope or catheter to visualize bladder and vesico-ureteral reflux?
Cystography
How is a renal biopsy usually performed, and what is the most important risk to remember?
Under CT or US guidance
Risk for bleeding
What is the term for an invasive endoscopic study that utilizes a scope to examine the bladder under local or general anaesthesia?
Cystoscopy
What are the three systems which maintain pH balance?
Buffer system
Respiratory system
Renal system
How do the kidneys maintain pH balance?
Reabsorb and create bicarbonate (HCO3-)
Excrete hydrogen ions (H+)
What is the term for an acid-base imbalance related to carbon dioxide?
Respiratory acidosis/alkalosis
What is the term for an acid-base imbalance related to bicarbonate?
Metabolic acidosis/alkalosis
What are 2 causes for metabolic alkalosis?
Vomiting and NG suction (loss of stomach acid > excess HCO3-)
What are 3 causes for metabolic acidosis?
- Diarrhea (loss of HCO3- from intestines)
- Renal failure (H2 retention)
- DKA
What are 2 causes for respiratory acidosis?
- Conditions that cause CNS depression (low RR):
-Head trauma
-Post-op
-Opioids & alcohol - Conditions that cause impaired gas exchange:
-COPD
-Asthma
-Pneumonia
What is the cause of respiratory alkalosis?
Conditions that cause increased RR, e.g. panic attack
What is the normal range for pH?
7.35-7.45
What is the normal range for CO2?
35-45
What is the normal range for HCO3?
22-26
How to determine if a person is in acidosis or alkalosis?
Determine which side the pH leans to more
How to determine whether an acid-base imbalance is metabolic or respiratory?
Match the pH with its partner
How to determine if an acid-base imbalance is compensated, uncompensated, or partially compensated?
- Compensated: pH normal
- Uncompensated: pH abnormal, one value of A+B is normal
- Partially compensated: pH abnormal, A+B abnormal
What is the most common cause of AKI?
Acute tubular necrosis (ATN)
What are the 2 most common causes of CKD?
Diabetes & hypertension
What are the 3 categories of etiologies for AKI?
Prerenal: impaired blood flow
Intrarenal: impaired filtration
Postrenal: impaired urine flow
What 2 values are used to classify AKI?
GFR & urine output
What is the most common early symptom of renal cell carcinoma?
Asymptomatic
What are 4 examples of procedures for noninvasive bladder cancer?
- Electrocautery (transurethral resection with fulguration)
- Laser photocoagulation
- Open loop resection of polyp
- Segmental cystectomy
What is the indication for partial or radical cystectomy with urinary diversion formation?
Invasive bladder cancer or involving the trigone
What are 4 uses for central lines?
- Frequent, long-term, or rapid administration of fluids/medications
- Hemodynamic monitoring
- Blood sampling
- Dialysis
