For about 2 years I have experienced "peeing sand". This started with an occurance every 2-3 months or so and now it has grown much more frequent. Sometimes it will happen miltiple times in one day, sometimes nothing for weeks. At times, it looks like about a tablespoon of sand that is expelled, but sometimes the sand is expelled together in a gritty clump. I can feel a pressure and warmth at the bladder sphincter and urethra when there is sediment present and ready to pass. Rarely does this sediment pass during actual urination. Instead, I will urinate and feel the need to urinate again, and if I force it, I will pass the sediment.
I have had multiple UAs done with no signifigant findings and a CT done, which showed no stones. I have tried limiting caffeine, drinking nothing but water, but nothing notes a difference in symptoms. I have been put on Potassium Citrate to alter my urine pH with no change in symptoms.
This occurs at all times of day, all levels of hydration, and with/without an empty stomach. When dried, the sediment is crystalline and powdery looking but not hard and calcified.
I have been to a urologist and he has not been able to make any diagnosis. Do you possibly have any suggestions on what could be causing this?
