I am having oily bubbles in my urine,what can cause this?

Not Sure!: Urine is filtered through kidney and it is composed of water and solutes (combination of different materials that are waste and excess of body need). Please check that there are no creams or ointment applied to the genital area when taking the urine sample and if it is still there, you might need to take a sample to the doctor for testing.

See below: Passing air/bubbles during urination (pneumaturia) usually indicative of a fistula (opening) between the bowel and bladder most commonly caused by diverticulitis or colon cancer. Less often by a UTI. Otherwise, IF you're noticing bubbles only IN the toilet water, can be caused by excess protein in the urine but more often is insignificant and related to force of urine flow or type of bowl cleaner.
