N14.4

Clinical Causes: Prolonged or excessive use of certain medications such as antibiotics, non-steroidal anti-inflammatory drugs (NSAIDs), or chemotherapy agents Exposure to environmental toxins including lead, mercury, or pesticides Inhalation or ingestion of industrial chemicals and solvents like toluene, carbon tetrachloride, or ethylene glycol Use of herbal medicines or supplements that contain nephrotoxic ingredients Intravenous contrast media used during diagnostic imaging procedures Acute poisoning incidents involving ingestion of toxic substances Occupational exposures in industries like mining, manufacturing, or chemical processing

Key Symptoms: Decreased urine output or dark-colored urine Swelling or edema in legs, ankles, or around the eyes Fatigue and weakness Nausea and vomiting Shortness of breath in severe cases Elevated blood pressure Signs of kidney failure such as confusion or decreased consciousness in advanced stages Laboratory findings indicating abnormal kidney function, including increased blood urea nitrogen (BUN) and serum creatinine

Diagnosis Path: Detailed medical history focusing on potential toxin exposure Physical examination looking for swelling or other signs of kidney issues Blood tests measuring BUN, serum creatinine, and electrolytes Urinalysis to detect abnormal substances, protein, or blood Imaging studies such as ultrasound to assess kidney structure Possibly, kidney biopsy to evaluate tissue damage if diagnosis remains uncertain

Treatment Protocols: Immediate removal or avoidance of the identified toxin Supportive care including hydration to flush out toxins Medications to manage symptoms such as hypertension or edema Dialysis in severe cases of kidney failure Monitoring and managing electrolyte imbalances Treating underlying infections or other contributing factors
