The presence of white clumps in urine may also be an indicator of a rather serious condition that needs urgent medical attention. Sediments in alkaline urine may be associated with phosphate debris. This is a rather common occurrence; hence no need to be worried. The white stuff could be a result of detached walls of the urinary tract lining. Fungus and yeast in the urinary tract may also lead to this problem. Under normal circumstances, urine is clear and its color ranges from yellow to amber. Normally, urine is free of fungi, bacteria and viruses, but rather fluids and waste products from the body. A bacterial infection in the urinary tract can cause the urine to be cloudy and have white tiny particles suspended within. This type of infection occurs when bacteria known as Escherichia coli attaches to the opening of the urethra and start spreading. If you suspect that you are suffering from UTI, it is advisable to see a doctor immediately as the infection can spread past the bladder and affect the kidneys as well. If the white stuff appears like sand granules, it may be an indicator that you are suffering from kidney stones. If you have ever suffered from kidney stones, the likelihood of the condition recurring is very high. Subsequent recurrence of kidney stones will not only happen in the kidneys, it will also affect other parts of the tract. This can cause varying complications and symptoms within the tract. As such, kidney stones could be the cause of the white clumps in urine. Fungal infections, like candidiasis infection, have also been known to cause a white stuff in urine. Other conditions that can lead to the production of white suspensions in the urine include polyps and bladder cancer.
