What are the symptoms of posterior urethral calculi?

There are two main symptoms of posterior urethral calculi, one is urethral pain, and the other is hematuria. Because the stones in the bladder may cause urethral obstruction after entering the posterior urethra, the stones are embedded in the urethra and washed by urine. After the impact of the stones, it will cause tingling in the urethra, causing stones to damage the urethral mucosa, causing damage and rupture of capillaries on the surface of the urethral mucosa, and internal red blood cells to enter the urine. The patient may show fresh blood dripping and pink urine when urinating, with gross hematuria. If the stone is small, it can be washed out of the body smoothly by urine. If the stone is large, it is embedded in the posterior urethra and cannot be discharged. It is necessary to go to the urology department for surgical treatment. After the posterior urethral stone is pushed into the bladder with a urethral probe, holmium laser lithotripsy under transurethral cystoscope is performed.
