Video Article: How Stones Form

MeThis is the first of what may become a series of articles done as videos.

The site is now a reasonably complete knowledge base but many of the ideas are hard to get and there is a lack of overview materials that are integrative.

That is what I plan for these video articles to do.

This first one tells about how crystals form and how they form specifically in kidneys to create stones and nephrocalcinosis.

It draws upon many of the articles as a base and pulls them together into one narrative.

It also adds materials not found anywhere else on the site because best presented in a video format.

Please let me know what you think.

Regards, Fred Coe

    Good day Dr Coe. Very informative video. Im 36 and have had 3 x calcium oxalate stones in the past 9 years. I studied Biochestry so im interested in the biology in ocurrence and preventing these nasty buggers.
    My last small (2mm) stone was treated with ESWL which got me thinking. For a mineral stone to form the different molecules have to bind to each other. The bigger the surface area the easier/faster they will bind. With ESWL they break a stone up in millions of small sandlike particles. According to my logic if some of this “sand” remains in kidney it would speed up formation of new stones? Does the kidney excrete all this broken pieces or could some remain in the kidney?
    Has there been any research done on an increase of recurrence after ESWL?

      Hi Albert, You are an astute thinker – yes, work has been done. SWL has virtues and some drawbacks. For prevention we need an organized approach. Here is one. For calcium oxalate stones not due to systemic disease – probably what you have – this is a very good summary of treatment. Be sure to read both articles. Regards, Fred Coe

        Thank you for the reply and informative articles. Your work gives so many of us a good understanding and idea on how to better deal with our unfortunate situation. I will be doing my best to prevent future occurrence.

      Dear Jose Carlos, Thank you for watching, and for remembering. I do so miss Jaime Herrera Acosta, and I shall never forget my all too brief time sharing your graceful moonlit Acapulco life, where all the women are beautiful and no one goes out for the evening until midnight or comes home until dawn. Withall, the science was terrific, and the people, too. Warmest personal regards, Fred

    Dear Dr Coe, thank you for this informative and somewhat entertaing video. I love that you did this. It is so telling and well done. I for one, hope you definitely continue to make these videos. When you have a disease like msk it effects your cognitive abilities also and a comprehensive video like this is so much easier to follow, then papers and articles. This could be a redundant question I’m not sure but do we know exactly why some of us make oxalate stones, and others make CaP brushite and hydroxyapatite stones.?
    Thank you again doctor for this video and all of your articles we are so lucky to have crossed paths. Best regards Laurie

      Thank you, Laura; I am doing more. As for the phosphate and brushite stones, the main factor is urine pH – higher with phosphate stones; why a higher pH? That is our current research. There is no way to lower it. Warm Regards, Fred

    Hi Dr. Coe,
    Well done! This topic is particularly well suited for video. It really helped me to visualize crystallization, kidney anatomy, plaques, plugs and more. The “further reading” section is a good idea too.
    This video is also a nice complement to your helpful piece on Citrate and the Ostwald Limit. Your IH article with the wonderful bathtub analogy (one of my all-time favorite articles) could possibly be a good candidate for a future video.
    As for style, thankfully you’ve kept it interesting and avoided the all too common model of “talking PowerPoints” in which a subject matter expert off screen simply reads dry, bulleted slides to you for hours.
    A table of contents with times could be a helpful addition.
    This web site offers an incredible wealth of profoundly useful and helpful information. I send all my friends with stone/bone issues. Thank you again for all you do.
    Best regards, Al

    Fascinating Fredric! I’m hoping our MSK members will all be watching this video, so informative seeing as most do make stones, nephrocalcinosis and most likely have duct pluggings although not specifically diagnosed, in fact very few have heard of them.
    I’m hoping a future video will show how MSK tubule stones are formed!
    Thank you so much for your helpful work!

    Well done, Dr. Coe! My advice is rather than present one long video, you may want to break these types of programs into numerous smaller segments so it’ll be easier for your viewers to watch over time.

    By the way, now that you’ve become a big-shot producer, I hope this doesn’t mean you won’t have any time to do research.

    I was very interested in your video. The section on Cystine stone formation was very informative since that is the type of stone former that I am. I am looking forward to your video concentrating on this.

    Tremendous, Fred!! You have painted a vivid picture of the stone formation process that is a work of art. I really admire the way you have been able to bring together basic scientists, kidney specialists and surgeons to make this in depth understanding possible.
