Read more about how to prevent the recurrence of urinary stones after surgery. First of all, to accurately estimate the cause of stones and to guide post-operative prevention, more precise results of stone composition analysis are needed to provide targeted dietary guidance to patients. One ideal method for physical analysis is infrared spectroscopy. Only a sesame-grain sized stone specimen is needed to precisely analyze the composition of stones. Compared to simply drinking more water, this method is individually targeted for the prevention of stone patients. After lithotripsy, surgery or self-excision, stone specimens can be collected and sent for testing, and depending on the specific stone composition, diet can be used to intervene in the amount of stone forming substances in the patient’s urine, pH and stone formation environment.
