Husband, age 70, creatinine level 1.8, up from 1.6 five weeks earlier, BUN 34, up from 28 in March.(0.7-1.3, 6-20 normal for lab.) I can find blood test records between 1993 and 1996, and creatinine levels ranged between 1.6 and 1.3, BUN between 20 and 27(0.6 - 1.5 5-25 normal for lab). He had extreme pain in area of kidney in 1969, hospitalized twice, no one could figure out what was wrong, tests said no kidney stone. Hypertension(178/118) diagnosed in 1974, cause said to be from scars on right kidney, which is where he had the pain five years earlier. He's taken a variety of medications for hypertension, is now taking lizinopri, also takes Actos for Type 2 Diabetis, which was diagnosed ca 2000.
I know we need to consult a nephrologist to sort things out. My questions are(1) is kidney disease likely and(2) if so, can we wait a month or so to see a specialist? We live in a small town and will have to travel to find a specialist. Husband is due to have his sinus reamed out next week, tends to bleed from anything above the shoulders, which means travelling won't be easy. Thank you for any/all help.
