As a Urologist, i can understand your anxiety. Your father has diabetic nephropathy, with renal failure and hypertension. He needs to be tested to know the cause for his chronic renal failure. He needs to see a Urologist for prostate enlargement and do these tests:1. Urine routine, culture and ACR.2. Blood routine, creatinine,PSA, electrolytes,HbA1C,and LFT.3. Ultrasound-KUB, with residual urine and THUS. These reports will give an idea, about cause for renal failure. If youve any doubts, send the reports to me, as a direct question. Chat Doctor. Manga.
