The pain in the small abdomen of men is recommended to go to the hospital for relevant examinations to clarify the specific causes to deal with the symptoms: first, if the examination confirms the presence of bladder stones or urethral stones, it is recommended to undergo cystoscopic lithotripsy to remove the relevant lesions and then the pain can be relieved or disappeared. Second, if the test is acute cystitis or urethritis, it is recommended to choose antimicrobial treatment according to the results of urine culture, such as intravenous infusion of levofloxacin hydrochloride injection, cefuroxime sodium for injection and other drugs for treatment. After the inflammation is controlled, the symptoms can be relieved or disappear. Thirdly, if ureteral stones are present at the time of examination, extracorporeal shock wave lithotripsy treatment or hospitalization for surgery to remove the stones in the body is recommended to achieve a complete recovery. Fourthly, if there are tumors in the urinary tract, such as bladder tumors, hospitalization is recommended to completely remove the tumor tissue in the body through minimally invasive bladder surgery to alleviate the patient’s symptoms.
