What are the differences between urinary retention and urinary retention?

There is no such thing as retention of urine in medical terms. There is only retention of urine. The so-called retention of urine means that the kidneys can normally produce urine, but outside the bladder neck, due to various reasons, a large amount of urine is blocked and retained in the bladder. It cannot be discharged normally. The causes of retention of urine are normally caused by prostatic hyperplasia, urinary tract infection, urethral stricture, neurogenic bladder and other diseases. In the early stages of symptoms, it may only affect normal urination, resulting in poor urination, there will always be a feeling of insufficient urine. As the disease progresses, it will show that the lower abdomen is full and normal urination cannot be performed. At this time, severe urinary retention will form, and it is necessary to use a catheter to drain urine from the bladder as soon as possible. Otherwise, the consequences will be very serious, and may even cause bladder damage.
