Hydronephrosis is caused by obstruction of urine before the renal pelvis. The obstruction causes dilation of the nephron tubules and flattening of the lining of the tubules within the kidneys which in turn causes swelling of the renal calyces. [4] Hydronephrosis can either be acute or chronic. In acute hydronephrosis, full recovery of kidney ...
Secondary causes of nephrotic syndrome have the same histologic patterns as the primary causes, though they may exhibit some differences suggesting a secondary cause, such as inclusion bodies. [24] They are usually described by the underlying cause, such as: [citation needed] Diabetic nephropathy: is a complication that occurs in some diabetics ...
In the longer term, obstruction of the urinary tract may cause: [citation needed] Bladder stones; Atrophy of the detrusor muscle (atonic bladder is an extreme form) Hydronephrosis (congestion of the kidneys) Hypertrophy of the detrusor muscle (the muscle that squeezes the bladder to empty it during urination)
It is the most common cause of hydronephrosis detected in utero and is the most common anomaly detected on prenatal ultrasounds. [ 1 ] [ 2 ] It occurs in approximately 1 in every 1500 live births, is most commonly seen in males, involves the left ureter twice as often as the right ureter.
Postrenal azotemia and hydronephrosis can be observed following the obstruction of urine flow through one or both ureters. [ 17 ] Pain in the lower-left quadrant can sometimes be confused with diverticulitis because the sigmoid colon overlaps the ureter, and the exact location of the pain may be difficult to isolate due to the proximity of ...
The most common cause of blockage necessitating a nephrostomy is cancer, especially ovarian cancer and colon cancer. Nephrostomies may also be required to treat pyonephrosis , hydronephrosis and kidney stones .
Common Causes of Depression. Much like humans, dog depression can be triggered by various reasons. Sometimes, it’s obvious. Other times, however, the triggers are more subtle, nebulous, and ...
Interstitial nephritis is uncommon (<1% incidence) in patients without any symptoms but occurs in about 10-15% of hospitalized patients with acute kidney injury of unknown cause. [2] While it can occur in patients of all ages, it is more common in elderly patients, perhaps due to increased exposure to drugs and other triggering causes. [2]
