Frequent Urination
Kidney stones’ greatest danger is their possibility of obstructing urine flow, causing a person to urinate more frequently. The result could cause a backup of urine in the kidneys, leading to a painful kidney infection (pyelonephritis) and possibly permanent damage. Kidney stones that cause obstruction may also lead to further complications, such as blood in the urine (hematuria), fever, chills, nausea, vomiting, or back pain.
Urinary tract infection due to kidney stones is less common than obstruction. However, as they travel down the urinary tract, they can irritate the lining of the bladder and ureter. This irritation can cause an infection that may spread to the bloodstream (sepsis). If not treated promptly with antibiotics, sepsis can be fatal.
Pyelonephritis can occur if a stone becomes lodged at any point along its path or if a stone causes an obstruction. Pyelonephritis requires hospitalization and antibiotic treatment for several days. It could also lead to permanent kidney damage. Therefore, you must seek medical attention immediately if you experience kidney stones or pyelonephritis symptoms.
