Urinary Disorders

Cause of Multiple Kidney Stones



My daughter has had seven kidney stones in the past seven months. She has had three lithotrypsies, the most recent one month ago. A CT scan done this week showed 4 new stones. She`s had metabolic testing that showed a high amount of calcium and oxalates in her blood, so has carefully followed the diet given her for the last month, as well as drinking lots of fluids, yet she continues to make stones. She also has polycystic ovarian syndrome and had a hysterectomy three years ago--could any of these problems be related to that? She is also a smoker, 27 years old.


She also needs a PTH (parathormone) level and 24 hour urine collections. The stones themselves should be sent for analysis. Further testing will depend on these.
