@science.nature: What started as a fever and sharp pain turned into a medical case doctors would not forget. In December 2023, a 20-year-old woman in Tainan, Taiwan, identified by the name Xiao Yu, went to Chi Mei Hospital after developing a fever and severe pain on the right side of her lower back. At first, doctors suspected a serious kidney problem. An ultrasound showed that her right kidney was badly swollen, and blood tests suggested an infection. Then came the bigger surprise. A CT scan showed that her kidney was packed with stones, some measuring between 0.5 and 2 centimeters. Doctors first treated the infection with antibiotics and inserted a tube to drain the kidney. After her condition improved, urologist Dr. Lin Caiyang performed a minimally invasive procedure and removed more than 300 kidney stones. Xiao Yu later said she rarely drank plain water and often chose other drinks instead. Thankfully, she recovered and left the hospital several days later. Doctors also noted that kidney stones can have many causes, including diet, genetics, low fluid intake and metabolic problems.
