Pyelonephritis is an acute UTI (Urinary Tract Infection) of the kidney.
It originates from the complication o cystitis. The bacteria from the bladder can spread to the kidney through the ureter. It is the cause of kidney infection.
Symptoms are lumbar pain and high fever.
The diagnosis and treatment must be immediate to have a full recovery. Delay may result in unpredictable progression.
Chronic pyelonephritis is less common and is a complication of dysfunctions like reflux of urine from the bladder to the kidney or chronic kidney obstructions.
We define uncomplicated pyelonephritis as when it occurs in non-pregnant, pre-menopausal women without relevant urologic abnormalities or other chronic diseases.
Acute pyelonephritis is a complication of lower UTI (urinary tract infection), usually cystitis. The bacterial count increases in the bladder and can spread up through the ureter into the kidney.
The risk of kidney infection increases:
Usually requires immediate IV antibiotic treatment. Complicated infection often requires kidney drainage to decrease the back-pressure related to obstruction (insertion of a tube in the skin of the lumbar area, directly into the kidney; insertion of an internal conduit in the ureter).
Uncomplicated kidney infection regards non-pregnant, pre-menopausal women with no chronic diseases and urological abnormalities.
It requires prompt IV antibiotic treatment, and the prognosis is always good with complete recovery.
The infection in pregnancy requires careful attention, complex antibiotic treatment and possible drainage of the affected kidney.
Kidney infection with obstruction and renal back-pressure is an emergency. We must treat it with a combination of antibiotic therapy and renal drainage.
The treatment must be prompt because of the risk of a life-threatening, generalized blood infection (sepsis).
