Question

identify the type of renal failure that results from bilateral obstruction of urine flow:

Answer 1

Introduction

Kidney failure occurs when your kidneys lose the ability to sufficiently filter waste from your blood. Many factors can interfere with your kidney health and function, such as:

• * toxic exposure to environmental pollutants or certain medications
• * certain acute and chronic diseases
• * severe dehydration
• * kidney trauma

symptoms include:

• * a reduced amount of urine
• * swelling of your legs, ankles, and feet from retention of fluids caused by the failure of the kidneys to eliminate water waste
• * unexplained shortness of breath
• * excessive drowsiness or fatigue
• * persistent nausea
• * confusion
• * pain or pressure in your chest
• * seizures
• * coma

5 types of kidney failure

There are five different types of kidney failure:

# Acute prerenal kidney failure

Insufficient blood flow to the kidneys can cause acute prerenal kidney failure. The kidneys can’t filter toxins from the blood without enough blood flow. This type of kidney failure can usually be cured once your doctor determines the cause of the decreased blood flow.

# Acute intrinsic kidney failure

Acute intrinsic kidney failure can result from direct trauma to the kidneys, such as physical impact or an accident. Causes also include toxin overload and ischemia, which is a lack of oxygen to the kidneys.

The following may cause ischemia:

• * severe bleeding
• * shock
• * renal blood vessel obstruction
• * glomerulonephritis

# Chronic prerenal kidney failure

When there isn’t enough blood flowing to the kidneys for an extended period of time, the kidneys begin to shrink and lose the ability to function.

# Chronic intrinsic kidney failure

This happens when there’s long-term damage to the kidneys due to intrinsic kidney disease. Intrinsic kidney disease develops from a direct trauma to the kidneys, such as severe bleeding or a lack of oxygen.

# Chronic post-renal kidney failure

A long-term blockage of the urinary tract prevents urination. This causes pressure and eventual kidney damage.

# Bilateral hydronephrosis

Bilateral hydronephrosis is the enlargement of the parts of the kidney that collect urine. Bilateral means both sides.

# Causes

Bilateral hydronephrosis occurs when urine is unable to drain from the kidney into the bladder. Hydronephrosis is not itself a disease. It occurs as a result of a problem that prevents urine from draining out of the kidneys, ureters, and bladder.

Disorders linked with bilateral hydronephrosis include:

• * Acute bilateral obstructive uropathy - sudden blockage of the kidneys
• * Bladder outlet obstruction - blockage of the bladder, which does not allow drainage
• * Chronic bilateral obstructive uropathy - a gradual blockage of both kidneys is most often from a common singular obstruction
• * Neurogenic bladder - poorly functional bladder
• * Posterior urethral valves - flaps on the urethra that causes poor emptying of the bladder (in boys)
• * Prune belly syndrome - poorly emptying bladder that causes distention of the belly
• * Retroperitoneal fibrosis - increased scar tissue that blocks the ureters
• * Ureteropelvic junction obstruction - blockage of the kidney at the point where the ureter enters the kidney
• * Vesicoureteric reflux - backup of the urine from the bladder up to the kidney
• * Uterine prolapse - when the bladder drops down and presses into the vaginal area. This causes a kink in the urethra, which prevents the urine from emptying out of the bladder.
