Renal calculi typically present with sudden and severe colic pain in the waist and abdomen, which may radiate to the lower abdomen and perineum, accompanied by gross or microscopic hematuria. Some patients experience frequent urination, urgent urination, nausea, vomiting, and abdominal distension.Urinary tract obstruction caused by calculi can lead to hydronephrosis. When complicated with infectio
