TMI Warning

My efforts to drink more water throughout the day have dramatically reduced the number of kidney stones I produce. During the last few weeks, however, I have worked very long days at the River House. Combined with very high temperatures, I have been more dehydrated than usual. Predictably, this has given rise to a new batch of kidney stones. This one, the largest of eight I have passed over the last two days, measured 3mm and has a composition I have not observed before. Kidney stones are composed of combinations of calcium, oxalate, urate, cystine, xanthine, and phosphate. When I have more free time, I will try to figure out what the reddish addition is to my normal calcium oxalate stones.
