Why do urethral stones cause hematuria, and how should urethral stones be treated?

Hematuria caused by urethral stones mainly results from the stone scratching the urethral mucosa during its passage, leading to blood in the urine during urination. Additionally, patients often experience significant symptoms of frequent and urgent urination, along with pain during urination. Some patients may develop concurrent infections, which could markedly worsen their symptoms. When urethral stones are severe, hematuria may occur, and timely examination and treatment are necessary; surgical intervention may be required when indicated.
