Urinary incontinence, also known as overactive Functional urinary incontinence Urge urinary incontinence Reflex urinary incontinence Stress urinary incontinence Overflow urinary incontinence Overflow urinary incontinence is the involuntary release of urine caused by an overfilled bladder, often in people who cannot fully empty their bladders. Mixed urinary incontinence Mixed urinary incontinence refers to the occurence of multiple types of incontinence – usually stress and urge incontinence. What is urinary retention? Urinary retention, or ischuria, is the inability to fully empty the bladder, and it may or may not coexist with urinary incontinence. It can be caused by factors such as immobility, medical conditions like BPH, disk surgery, or hysterectomy, and side effects of various medications including anesthetics, Signs and symptoms Here are the common signs and symptoms for patients with problems with urinary elimination: Urinary incontinence • Reports of urine leakage. Unintentional discharge or leakage of urine. • Leakage of urine during physical activities. Incontinence that occurs during actions like coughing, sneezing, or exercising. • Urgency to urinate that cannot be controlled. Strong and sudden urge to urinate that is difficult to postpone or control. • Frequent urination. Need to urinate more often than usual. • Dampness or wetness in the underwear or clothing.

Anuria is the inability to urinate or discharge urine. The word itself literally translates to “no urine.” It can be a symptom of various metabolic and volume status disorders, or it can be a problem stemming from an abnormality of the kidney’s themselves, or even of the heart in certain circumstances. A related medical condition is called oliguria, which means that urine production is less than 500ml per day. What causes anuria? Advertisement There are generally three major types of causes of anuria, and they are as follows: Prerenal causes: Problems occurring outside the kidneys that affect urine production. These may include: Hypovolemia: Occurs due to fluid loss that can be a result of excessive blood loss, diarrhea, vomiting, burns, diuretic medication, pulmonary edema, and fluid loss due to operations procedures. Low systemic vascular resistance: Can occur in severe infectious states such as sepsis or shock. Severe allergic reactions to certain drugs and intake of antihypertensive drugs may also be a cause. Heart failure: Conditions such as myocardial infarction, decreased blood supply to the heart, cardiomyopathy, and arrhythmias may be a cause. Other: Sudden compression of the renal vein or inferior vena cava, Renal causes: Issues in the kidneys themselves that can be due to an abnormality in the structure of the glomerulus and renal tubules, drastically reducing urine output. This can be caused by autoimmune disorders, glomerulonephritis, nephrotoxic drugs, ACE in...

Definition There is no standard accepted definition of AKI. Generally accepted criteria (KDIGO modification to RIFLE and AKIN criteria) involve the following: • 5.4), chem 10, UA with microscopy, urine sediment exam, FENa, FEUrea, urine osmolality (UNa, UCr, UOsm+/- UUrea), spot UProt/UCr, renal U/S (see below). • Consider screen for GN if high clinical suspicion or hematuria on UA: ANA, C3, C4, ANCA. • If exam and UA are consistent with GN, additional tests are recommended . • Check CK if concern for rhabdomyolysis (heme without RBC on UA, elevated potassium). • Note: elevated risk of ATN only when CK>15,000-20,000 (but may be seen at lower levels if concomitant sepsis, prerenal azotemia, or acidosis). • Interpreting biochemical markers and urine electrolytes ( table 2): • Calculate FENa [(UNa/PNa ÷ UCr/PCr) x 100] if patient is oliguric. • If patient has recently used diuretics, can calculate the FEUrea [(UUrea/PBUN ÷ UCr/PCr) x100].
