What are the symptoms of acute pyelonephritis?

Pyelonephritis refers to inflammation of the kidney pelvis, most of them are caused by bacterial infection. Usually, pyelonephritis can be pided into two kinds of acute pyelonephritis and chronic pyelonephritis. Among them, chronic pyelonephritis is an important cause of chronic renal insufficiency. What specific symptoms here to introduce you with pyelonephritis:

1, acute pyelonephritis.

(1) symptoms of systemic infection

Acute onset, may have chills, fever, body temperature at 38 ~ 39 C, also can be as high as 40 C, not a hot type, with headache and body aches, nausea, vomiting, abdominal distension, diarrhea and even.

(2) urinary symptoms

Some patients also have symptoms of kidney infection, urinary tract infection, including frequent micturition, dysuria. May be unilateral or bilateral renal enlargement and tenderness, small side of the back infected areas have abdominal tenderness, sometimes severe contraction, the patient may feel intense paroxysmal pain, which is caused by unilateral ureteral spasm (renal colic). This kind of colic may be caused by infection or kidney stones caused by ureteral irritation. Chronic pyelonephritis, pain can be blurred, can be repeated fever or no fever. Children with systemic symptoms, urinary symptoms.

2, chronic pyelonephritis

The course of pyelonephritis over half a year, and one of the following circumstances, can be diagnosed as chronic pyelonephritis, intravenous pyelogram showed renal pelvis deformation and stenosis; kidney shape can be uneven, and two renal size; renal tubular function with diffuse damage.

The symptom is lighter than the acute period, sometimes can appear as asymptomatic urine. More than half of the patients with acute pyelonephritis history, followed by symptoms of fatigue, fever, anorexia and lumbago, and accompanied by frequent urination, urgency, dysuria and other urinary irritation symptoms. Acute onset also occurs. The course of more than half a year or 1 years for chronic pyelonephritis, recently developed renal pelvis had scar formation, intravenous pyelography see renal pelvis seeper, kidney shape deformation, not smooth, or two sizes called kidney of chronic pyelonephritis. There may be damage to renal tubular function, such as decreased concentration, low permeability, low specific gravity urine, nocturia and renal tubular acidosis. To the late stage, there may be damage to glomerular function. Renal hypertension is caused by chronic pelvic inflammatory disease, and it is generally believed that patients with high renin and some of the release of vasoconstrictor peptides and vascular sclerosis, stenosis and other diseases. After a small number of patients with unilateral renal disease, hypertension can be improved.

(1) urinary tract infection

Common intermittent asymptomatic bacteriuria, frequent urination, urination discomfort of lower urinary tract symptoms, mild flank or abdominal discomfort, intermittent fever and other performance.

(2) the symptoms of chronic interstitial nephritis

Manifestations of polyuria, nocturia and renal tubule dysfunction symptoms, late in tubulointerstitial damage, glomerular sclerosis appeared focal segmental, showed proteinuria or nephrotic syndrome, patients with poor prognosis and gradually progress to end-stage kidney disease. The mantle of pyelonephritis complicated clinical manifestations, easily repeated reaction. Is currently considered to be difficult to cure the disease and gradually progress.
