Acute pyelonephritis has pronounced symptoms. Typical manifestations of this inflammatory disease include:
• pain in the lower back, side, or lower back;
• increased urge to urinate, including at night;
• changes in the color of urine, the occurrence of sediment in it;
• the appearance of slight swelling of the lower extremities;
• feeling of thirst;
• indigestion (nausea and vomiting);
• general weakness;
• an increase in body temperature, often up to 39 C.
Inflammation of the kidneys can occur against the background of other pathologies of the genitourinary organs, including cystitis (in women) or prostatitis (in men).
If severe symptoms characterize acute pyelonephritis, then chronic pyelonephritis can proceed sluggishly and without distinct manifestations. Moreover, due to the lack of apparent complaints, patients often postpone the visit to the urologist. However, without treatment, the risks of complications increase, namely:
• purulent inflammation of the kidneys;
• arterial hypertension;
• renal failure;
• blood poisoning;
• renal necrosis, etc.
