which type of renal failure is caused by bilateral obstruction of urine flow

Chronic Bilateral Obstructive Uropathy Symptoms depend on the nature of the obstruction and where in the urinary tract the obstruction occurs. Some of the most common symptoms of chronic obstructive uropathy include: 1  Stronger and more frequent urge to urinate. 2  Difficulty initiating the flow of urine (urinary hesitancy). 3  Dribbling of urine, incontinence.

- Any type of urinary obstruction can lead to hydronephrosis. The most common types of obstruction are caused by prostate hypertrophy (enlargement), renal calculi that form in the renal pelvis or drop into the ureter, or urethral strictures.

- On ultrasound examination left kidney was normal, but right kidney was small and moderately hydronephrotic. The left kidney showed features of obstruction at the pelviureteric junction: gross hydronephrotic changes and delayed contrast excretion with nonvisualization of the left ureter (Figure 2). 3%) patients, hydronephrotic atrophy due to ureteropelvic junction obstruction in 2 (13.

- This resulted in bladder wall thickening and obstruction of the left ureter at the ureteral orifice into the bladder causing left sided hydronephrosis and thus requiring stenting. Note bladder wall thickening in the left lateral bladder wall from radiation induced cystitis (arrows). Contrast enhaced CT scan of the pelvis. A mass like lesion in the dependent portion of the bladder may represent a mass (arrows). However, this patient presented with gross hematuria.

Approach to Leg Edema of Unclear Etiology Distribution of edema: Unilateral. leg edema is generally due to a local cause such as deep vein thrombosis, venous insufficiency, or lymphedema. Bilateral. edema can be due to a local cause or systemic disease, such as heart failure or kidney disease. Generalized. edema is due to systemic disease.

What are the Causes of Atrophic Kidneys An obviously decreased kidney size is associated to poor prognosis in the patients. Usually, kidney atrophy can be divided into two types, unilateral kidney atrophy and bilateral kidney atrophy. And atrophic kidneys may be caused by the following conditions.

Renal agenesis Bilateral renal agenesis is a condition in which both kidneys of a fetus fail to develop during gestation. It is one causative agent of Potter sequence. This absence of kidneys causes oligohydramnios, a deficiency of amniotic fluid in a pregnant woman, which can place extra pressure on the developing baby and cause further malformations.

Overview Different types of ureteral obstruction have different causes, some of them present at birth (congenital). They include: Ureteral obstruction may be caused by: Duplication of the ureter, the tube that carries urine from the kidney to the bladder. This common condition, which is present at birth (congential), causes two ureters to form on the same kidney. The second ureter can be normal or only partially developed.

UPJ Obstruction Ureteropelvic junction (UPJ) obstruction is a blockage at the point where part of the kidney attaches to one of the tubes to the bladder (ureters). This blocks the flow of urine out of the kidney. UPJ obstruction mostly occurs in children. It often happens when a baby is still growing in the womb. This is called a congenital condition (present from birth). The blockage is caused when there is a narrowing of area between the ureter and the part of the kidney called the renal pelvis.

Urinary Tract Conditions 1 Polycystic kidney disease: A genetic condition resulting in large cysts in both kidneys that impair their function.  Acute renal failure (kidney failure): A sudden worsening in kidney function. Dehydration, a blockage in the urinary tract, or kidney damage can cause acute renal failure, which may be reversible.

- 1 The obstruction may occur at any level in the urinary collecting system from the kidney to the ureter to the bladder to the urethra.  Depending on the level of the cause, hydronephrosis may be unilateral involving one kidney or bilateral involving both.

Hydronephrosis The most common cause for this blockage is a kidney stone, but scarring and blood clots can also cause acute unilateral obstructive uropathy. A blocked ureter can cause urine to go back up into the kidney, which causes swelling. This backflow of urine is known as vesicoureteric reflux (VUR).

Ureteropelvic Junction (UPJ) Obstruction An obstruction also can be caused by compression of the UPJ by a blood vessel or irregularities in the fibrous bands around the ureter. If undiagnosed or left untreated, chronic UPJ obstruction can lead to significant kidney damage and the gradual loss of kidney function. This is especially true of patients who are diagnosed later in life.

Ureteropelvic Junction (UPJ) Obstruction Symptoms & Causes In a normal urinary system, urine flows from the kidney through the ureter and into the bladder. In children with a ureteropelvic junction (UPJ) obstruction, there is a blockage between the ureter and the kidney that can slow or block the flow of urine. In severe cases, the urine is unable to drain from the kidney, and can stretch the organ and cause permanent damage.

Kidney failure Causes of acute kidney failure include low blood pressure, blockage of the urinary tract, certain medications, muscle breakdown, and hemolytic uremic syndrome. Causes of chronic kidney failure include diabetes, high blood pressure, nephrotic syndrome, and polycystic kidney disease. Diagnosis of acute disease is often based on a combination of factors such as decrease urine production or increased serum creatinine.

Overview In more severe cases, it may be caused by a blockage in the flow of urine from the kidney(s) to the bladder, backflow of urine from the bladder to the kidney(s), or a blockage in the flow of urine out of the bladder. Read more about the causes of hydronephrosis.

Bilateral hydronephrosis 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.

- Postrenal causes of acute renal failure result in obstruction of the outflow tracts of the kidneys. Causes include prostatic hypertrophy, catheters, tumors, strictures, and crystals. Neurogenic bladder also can cause an obstruction. Because postrenal causes are readily reversible, it is imperative to exclude them.
