Urethral stone examinations are primarily divided into the following areas: Firstly, the physical examination provided by the clinical doctor which checks for urethral stones can be categorized into anterior and posterior urethral stones. For anterior urethral stones, one can feel a hard nodule inside the urethra with their hand. Combined with specific symptoms, such as sudden stabbing pain during urination or a sudden inability to urinate, and if there is a history of urinary system stones, then urethral stones might be considered. As for posterior urethral stones, they cannot be felt externally; if they are lodged at the prostate, a doctor might insert a finger into the rectum to touch the area around the prostate. If a hard nodule is felt upon pressing, then a posterior urethral stone might be considered. Secondly, a more accurate clinical exam is the plain film radiography of the urinary system, commonly known as X-rays. Generally, most stones contain calcium, and in such cases, the X-ray can reveal a hard nodule in either the posterior or anterior urethra, which can be diagnosed as urethral stones. Thirdly, the urinary system's CT scans can sometimes detect radiolucent stones, such as uric acid stones. It can also identify conditions like kidney hydronephrosis in the bladder and stones in other parts of the urinary system. If all examinations, including auxiliary checks, suggest the presence of urethral stones, treatment depends on the situation. If the anterior urethral stone is not large, stone retrieval may be performed. Posterior urethral stones are generally treated like bladder stones; after pushing them into the bladder using a cystoscope, the stones are broken down either by lithotripsy or laser.
