Surgery is the only curative modality but occasionally it can have some long term complication such as short bowel syndrome. We presented a case reporting a 63-year-old man who had subtotal colectomy with liver metastasectomy according to the colon adenocarcinoma, following the couple of months of surgery; he had acute kidney injury without any end-organ damage while he had a regular diet and nutrition. Following the regular treatment of renal failure, colorectal cancer recurrence was excluded and then he was discharged from the hospital with a normal serum creatinine level. The patient was admitted to the nephrology clinic again for acute renal failure within 3 weeks of last admission to the hospital. He also denied the insufficient oral water intake and nutrition, but laboratory examination revealed acute renal failure. We suspected for short bowel syndrome (SBS). Following the hydration, loperamide hydrochloride 10 mg/day was started and the patient was followed up with normal serum creatinine and uric acid levels. To the best of our knowledge, this is the first case report, in which a patient with short bowel syndrome presented with prerenal acute renal failure even though he had sufficient oral intake and nutrition and can be treated with hydration and loperamide hydrochloride.
