Reflux nephropathy is kidney damage (nephropathy) due to urine flowing backward (reflux) from the bladder toward the kidneys; the latter is called vesicoureteral reflux (VUR). Longstanding VUR can result in small and scarred kidneys during the first five years of life in affected children.
Reflux also increases risk of acute bladder and kidney infections, so testing for reflux may be performed after a child has one or more infections. In infants, the signs and symptoms of a urinary tract infection may include only fever and lethargy , with poor appetite and sometimes foul-smelling urine, while older children typically present ...
Mechanical: any structural abnormalities in the urinary tract, vesicoureteral reflux (urine from the bladder flowing back into the ureter), kidney stones, urinary tract catheterization, ureteral stents or drainage procedures (e.g., nephrostomy), pregnancy, neurogenic bladder (e.g., due to spinal cord damage, spina bifida or multiple sclerosis ...
On the other hand, sustained hypokalemia and hyperreninemia can cause progressive tubulointerstitial nephritis, resulting in end-stage kidney disease (kidney failure). With early treatment of the electrolyte imbalances, the prognosis for patients with classic Bartter Syndrome is good. [citation needed]
IgA nephropathy (Note: Contrast time of onset with Post-streptococcal Glomerulonephritis) - Most commonly diagnosed in children who recently had an upper respiratory tract infection (URI). Symptoms typically present within 1–2 days of a non-specific URI with severe flank / abdominal pain, gross hematuria (characterized by dark brown or red ...
Clinical symptoms in patients with pyonephrosis can range from frank sepsis (15%) to asymptomatic bacteriuria.Upon physical examination, the hydronephrotic kidney may be linked to a palpable abdominal mass. [4]
Renal tubular acidosis (RTA) is a medical condition that involves an accumulation of acid in the body due to a failure of the kidneys to appropriately acidify the urine. [1] In renal physiology, when blood is filtered by the kidney, the filtrate passes through the tubules of the nephron, allowing for exchange of salts, acid equivalents, and other solutes before it drains into the bladder as urine.
Fanconi syndrome or Fanconi's syndrome (English: / f ɑː n ˈ k oʊ n i /, / f æ n-/) is a syndrome of inadequate reabsorption in the proximal renal tubules [1] of the kidney.The syndrome can be caused by various underlying congenital or acquired diseases, by toxicity (for example, from toxic heavy metals), or by adverse drug reactions.
