There is no clear standard for how many seconds of waiting time is considered serious, but generally more than 30 seconds is considered more serious.
Waiting to urinate refers to the delay in urination urine can not be discharged, and under normal circumstances, urination can generally be a few seconds to have urine discharged, if the waiting time for more than 30 seconds, that is more difficult to urinate, the condition is more serious.
Most of the waiting time is caused by obstruction of the urinary tract, such as prostate hyperplasia, urinary stones or urinary tumors, etc. may lead to difficulty in urination, and some patients are unable to urinate even for a few minutes.
If the waiting time is long, you should go to the hospital in time to find out the cause and take treatment early.
