The most common symptom of bladder stones is pain, often episodic pain in the lower back or upper abdomen, severe and unbearable. The pain can travel along the ureter, radiating to the lateral abdomen and can also involve the labia. Then, there may also be hematuria; usually, it is microscopic hematuria, but a few patients may have gross hematuria, meaning that the urine visibly turns red during urination. Additionally, there may be symptoms of nausea and vomiting, possibly due to the stones causing mucosal ruptures in the kidney, ureter, or bladder, leading to inflammation. Furthermore, the stones might press on the intrinsic nerves of the ureter and intestines, causing nausea and vomiting, often accompanying renal colic. Another typical sign is bladder irritation, characterized by symptoms such as frequent urination, urgent urination, and painful urination.
