If you want to urinate but have no urine, it is recommended to go to the hospital for an examination to clarify the cause and then treat the problem accordingly. First, stones at the end of the ureter can cause the feeling of wanting to urinate and not urinating, which is often caused by frequent spasms and contractions at the end of the bladder and ureter due to the stimulation of stones at the end. In this case, extracorporeal shock wave lithotripsy or lithotripsy treatment is needed, and the stones will disappear naturally after they are discharged; second, infection, when acute cystitis occurs, it can cause increased bladder sensitivity, and a little urine stimulation can produce a strong desire to urinate, but because the urine volume is too small, it is impossible to urinate, After the infection is cured, the symptoms will improve or disappear. Third, for overactive bladder, oral tolterodine tartrate tablets and solifenacin succinate tablets should be taken after the diagnosis to inhibit frequent bladder contractions and slow down the above symptoms.
