How is post obstructive diuresis treated?

How is post obstructive diuresis treated?

Treatment of postobstructive diuresis consists of judicious fluid replacement with 0.45% saline (at a rate slightly less than urine output) and replacement of electrolytes. Urinary tract infections may occur due to urinary stasis.

How long does post ATN diuresis last?

Physiologic POD is self-limiting and generally lasts 24 hours. Pathologic POD generally lasts longer than 48 hours and can be exacerbated with excessive intravenous fluid replacement.

When does post obstructive diuresis occur?

Post-obstructive diuresis typically occurs after drainage of larger amounts of urine from the bladder, typically 1,500 cc or more.

Can urine retention cause electrolytes?

POD is not typically an issue unless the residual urine is 1500 cc or more. If the POD condition becomes pathologic, it can cause serious consequences such as dehydration, electrolyte abnormalities, hypovolemic shock, and even result to death.

What is the difference between polyuria and diuresis?

Polyuria (/ˌpɒliˈjʊəriə/) is excessive or an abnormally large production or passage of urine (greater than 2.5 L or 3 L over 24 hours in adults). Increased production and passage of urine may also be termed diuresis.

What doctor treats electrolyte imbalance?

A nephrologist is a specialist who diagnoses and manages electrolyte disorders.

How can you prevent diuresis?

Home Care

1. Avoid caffeine and alcohol.
2. Drink more water to stop dehydration.
3. Stop using diuretics if you don’t need them.

What is PCN placement?

Percutaneous nephrostomy (PCN) is a medical procedure that involves the placement of a small, flexible rubber tube or catheter through the skin into the kidney to drain the urine while using imaging as a guidance.

What is post-obstructive diuresis?

Post-obstructive diuresis is not typically a concern unless the post-void residual volume is greater than or equal to 1,500 cubic centimeters. Post-obstructive diuresis can cause serious consequences such as dehydration, electrolyte abnormalities, hypotension, hypovolemic shock, and even result in death.

Can salt loss diuresis be converted to post obstructive diuresis?

Salt loss diuresis can convert to post obstructive diuresis. A urinary Na greater than 40mmol/L suggests renal tubular injury. When replacing fluid aim to run the patient at a negative fluid balance ie replace 70-80% of what is lost in the urine. Running positive or in a euvolaemic state can prolong the diuresis.

What is diuresis and how is it treated?

Diuresis is a normal physiologic response to help eliminate excess volume and solutes accumulated during the prolonged obstruction. In most patients, diuresis will resolve once the kidneys normalize the volume and solute status and homeostasis is achieved.

How much fluid should be replaced during diuresis?

Most recommend replacing half to two-thirds of the urine output over a similar time period [13,10]. Excessive fluid replacement may actually perpetuate and prolong the diuresis [6,11,13].
