Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: history of present illness: the patient is a 76-year-old gentleman with a history of diabetes for 63 years, hypertension, hypercholesterolemia, who on work-up for hematuria was noted to have a right feeling defect in the renal pelvis. the brush biopsy of renal pelvis was suspicious for transitional cell carcinoma and he came back for elective right nephrectomy. past medical history: significant for diabetes, who is managed in the diabetes center, also paget's disease status post open reduction and internal fixation in , hypertension, hypercholesterolemia. allergies: no known drug allergies. medications: hydrochlorothiazide 25 mg q day, cardia 120 mg q day, aspirin 81 mg q day, pravachol and insulin. review of systems: he denied any history of chest pain, shortness of breath, or weakness. most recent stress test was normal. physical examination: during admission showed a well appearing overweight white gentleman in no acute distress. he is afebrile. blood pressure is 175/79 and heart rate is 73. he weighs approximately 190 lbs. his pupils are round, equal, reactive to light and extraocular movements are intact. his neck is supple, no lymphadenopathy, no carotid bruits. his chest is clear bilaterally to auscultation. heart has a regular rate and rhythm, no extra heart sounds, no murmurs. the abdomen is distended and somewhat firm with active bowel sounds. there is no palpable mass, no hepatosplenomegaly. rectal exam showed normal tone. the prostate feels smooth, there is no rectal mass, guaiac negative. extremities are well perfused with no obvious edema. pre-operative laboratory work showed a hematocrit of 39.7 and a stress test showed no reversible ischemia and ejection fraction was 66%. hospital course: on the patient was brought to the or for a scheduled right sided nephroureterectomy. the operation was complicated by excessive bleeding with estimated blood loss of 3,500 cc. the patient received 10 liters of crystalloids during the operation. postoperatively he was moved to intensive care unit for better management of the fluid status and his blood pressure. the patient was extubated on postoperative day #1 without complications. while in the intensive care unit he remained hypertensive. that required nitro drip to obtain adequate control. at the same time he also suffered from low urine output. he required multiple doses of iv fluid bolus. however, he responded to iv doses of lasix for diuresis. his creatinine stabilized at level of 2.1 to 2.4 from his baseline of 1.6. renal consult was obtained and the decreasing renal function was felt to be due to the transient hypoperfusion during the operation when his blood pressure was dropped to low 100's for approximately an hour. the patient's stay in the micu was otherwise uneventful. he was then transferred back to the floor on postoperative day #3. on the evening when he transferred to the floor, he experienced an episode of atrial fibrillation with rapid rate of around 160 times per minute and there were associated ischemic changes seen in the ekg. he required several doses of iv lopressor and iv diltiazem to slow down his heart rate and convert it back to sinus rhythm. a cardiac enzyme was sent and chest x-ray was also obtained. he was then transferred back to the intensive care unit for continuous iv infusion of diltiazem to control his heart rate. his heart rhythm converted to sinus rhythm a few hours after the iv diltiazem instillation. he remained to be stable for the micu stay. the etiology of this episode of atrial fibrillation without prior history remained unclear, however, it was thought that his status of fluid overload may contribute to the cause. on postoperative day #6 the patient was then transferred back to the floor in stable condition. he started to pass gas and diet was slowly restarted. on the day of discharge he tolerated a full diet without any problems. his central line and foley catheter was discontinued on postoperative day #8. he required a minimum amount of pain medication and made good amount of urine. his laboratory studies including cbc and electrolytes remained unchanged until the day of discharge. his creatinine level is 2.4 on the day of discharge. during this hospital stay the patient had very limited amount of physical activity. he feels weak in general and could not ambulate without significant help. therefore, he is arranged to be discharged to a rehab facility to help ambulating and regain his capacity of maintaining daily home activity. discharge medications: hydrochlorothiazide 25 mg q day, nph insulin 10 units in the morning, 6 units in the evening, insulin sliding scale with regular insulin, lopressor 25 mg , percocet po q 4-6 hours as needed and diltiazem long release 240 mg every morning. condition on discharge: stable. discharge status: to rehab facility. discharge diagnosis: 1. papillary transitional cell carcinoma status post right nephroureterectomy. , md dictated by: medquist36 procedure: nephroureterectomy diagnoses: pneumonia, organism unspecified acute posthemorrhagic anemia acute kidney failure, unspecified cardiac complications, not elsewhere classified atrial fibrillation malignant neoplasm of kidney, except pelvis urinary complications, not elsewhere classified diabetes with neurological manifestations, type i [juvenile type], not stated as uncontrolled
