<s>[INST] Hi there, I had an ultrasound scan as my GP thought that I had kidney stones. The radiologist told me that i had bilateral duplex kidneys. I experience pains around the kidney regions sporadically, and especially in the past few months. Calcium oxalate crystals were found in a urine sample hence why kidney stones were thought to be a possibility. Are the two conditions linked? What are the implications of bilateral duplex kidneys? Thanks, Jennifer [/INST] Hi, dearI have gone through your question. I can understand your concern. You have bilateral duplex kidney. It means you have duplication of kidney on each side and you have 4 separate kidneys. They drain in to single ureter each side or there may be two on both side. However if you don't have any other problems then no treatment is required. If you have infection of vesicouereteral reflux then treatment is required. Calcium oxalate crystals can be seen normally or associated with kidney stones. So if you have stone on USG then only treatment is required. Consult your doctor and take treatment accordingly.Hope I have answered your question. If you have any doubts then feel free to ask me. I will be happy to answer. Thanks for using health care magic. Wish you a very good health. </s>
