Severe back pain related to the urinary system typically originates from the kidneys or ureters. This type of pain is commonly referred to as renal colic. It is often sharp, wave-like, and may radiate toward the lower abdomen or groin.
Unlike muscular back pain, kidney-related pain is usually not affected by movement or posture changes and may be associated with urinary symptoms.
Kidney stones are the most common cause of severe flank pain. When a stone obstructs the ureter, it increases pressure within the kidney, causing intense pain. This may be accompanied by nausea, vomiting, or blood in urine.
Blockage of urine flow due to stones, strictures, or tumors may cause hydronephrosis (swelling of the kidney), leading to persistent back pain.
Infection of the kidney can cause flank pain along with fever, chills, and burning urination. This condition requires urgent antibiotic therapy.
Certain anatomical conditions may predispose individuals to recurrent obstruction and pain.
Immediate evaluation is necessary if back pain is associated with:
Evaluation typically includes:
CT imaging provides precise information about stone size, location, and obstruction severity.
Small stones may pass spontaneously with hydration, pain management, and medications that relax the ureter.
For ureteric or kidney stones not passing naturally, minimally invasive laser procedures are used to fragment and remove stones.
Large kidney stones may require percutaneous removal through a small keyhole incision.
Kidney infections require antibiotic therapy and sometimes temporary drainage procedures if obstruction is present.
Untreated obstruction can cause permanent kidney damage. Recurrent stones may lead to chronic kidney problems if not properly managed.
