Thank you so much for your experience with your two kidney biopsies. I told my nephrologist about taking Lunesta for over a year, stresses and death of my husband after being care for at home with two caregivers. He doesn’t think Lunesta can do damage to my kidneys. Because he finds no clues since my blood and urine test are okay except my current creatinine is at 1.5 and GFR at 36 thus a kidney biopsy was ordered. I am getting a second opinion from Stanford nephrology dept before agreeing to one. At 76 and poor health, I want very much to know if it is worth to get kidney biopsy and what possible things they are looking for. It is true that I am told to keep my blood pressure under 135/85 and blood sugar normal. He said diet doesn’t really help.
