Dr Mike Nguyen, Associate Professor of Clinical Urology at the Keck School of Medicine of USC in Los Angeles, CA, founded this site years ago and it has grown into a wonderful resource for patients. He is a superb stone surgeon and offers patients opportunities to ask questions and also write posts about their own personal experiences.
I am impressed with the level of patient involvement, and the strong orientation to the details of their clinical care.
From a scientific standpoint I think Dr Nguyen’s site is completely reliable, which is critical for patients and family members who want to be sure what they are reading is as true as science can make it.
Take a look at kidneystoners.org.
It is a site I can recommend without reservation: Quality, prominent medical director, university based, scientifically accurate, and very patient friendly.
