The location of painful urinary stones varies depending on the location of the stone: first, kidney stones are mainly located in the posterior lumbar region, and the pain may radiate to the posterior back or to the upper abdomen, usually at the intersection of the spine and the ribs, which is called the rib cage point. Secondly, if the stone is in the upper ureter, it is mainly located in the upper abdomen, and the pain may be accompanied by nausea and vomiting, and there is no clear fixed point, and the pain is diffuse. Thirdly, in the case of stones in the lower or final segment of the ureter, the pain is mainly located in the lower abdomen and can radiate to the scrotum, penis or vulva of women, accompanied by obvious symptoms of frequent and urgent urination. Fourth, the pain of urethral stones is mainly located in the urethra, which is characterized by continuous stabbing pain, which is sharply aggravated when urinating, and is accompanied by the symptoms of straining to urinate, bifurcation of urination, or blood dripping from the urethra, and may be accompanied by the inability to urinate in severe cases.
