CISPLATIN NEPHROTOXICITY IN A PATIENT WITH A SINGLE KIDNEY

OBJECI1VE: To describe a patient with a single kidney who experienced cisplatin-associated nephrotoxicity. CASE SUMMARY: A 78-year-old African-American woman with squamous cell carcinoma of the base of her tongue (T4NzM.) was admitted electively to our institution for the first cycle of chemotherapy. Her past medical history was significant for a left nephrectomy secondary to well-differentiated papillary transitional cell carcinoma of the left renal pelvis, hypothyroidism, asthma, and coronary artery disease. Her blood urea nitrogen (BUN) was 27 mgldL of urea, and serum creatinine was 1.2 mgldL. On admission she was hydrated adequately, and was treated with an evening dose of cisplatin 100 mglmz (180 mg) in 250 mL of NaCl 0.9 % solution in a 3-hour infusion, and a 5-day course of fluorouracil 1000 mglmz (1800 mg) in a 24-hour infusion. Serum creatinine and BUN concentrations following cisplatin administration were 1.1 mgld
