Patient presents with complaints consistent with renal calculi, including acute flank pain, radiating to the groin or lower abdomen.  Severity of renal colic is noted, ranging from mild discomfort to severe, incapacitating pain.  Onset of symptoms is documented, along with any associated nausea, vomiting, hematuria, or dysuria.  Patient history is reviewed for risk factors such as family history of kidney stones, dehydration, dietary factors, gout, hyperparathyroidism, or previous episodes of nephrolithiasis.  Physical examination findings, including costovertebral angle tenderness, are recorded.  Diagnostic workup may include urinalysis for hematuria, crystalluria, and infection;  serum creatinine and electrolyte levels;  and imaging studies such as non-contrast CT scan of the abdomen and pelvis for kidney stone identification, size, and location.  Differential diagnoses considered include pyelonephritis, appendicitis, ovarian cysts, and other causes of abdominal pain.  Treatment plan is based on stone size, location, and patient symptoms and may include pain management with analgesics such as NSAIDs or opioids, medical expulsive therapy with alpha-blockers, increased fluid intake, and monitoring for spontaneous stone passage.  For larger stones or those causing obstruction, urological consultation may be warranted for interventions such as lithotripsy, ureteroscopy, or percutaneous nephrolithotomy.  Patient education is provided regarding preventive measures, including dietary modifications, hydration, and medication management.  Follow-up care is scheduled to monitor symptoms, stone passage, and renal function.
