What does bladder fullness mean?

Poor bladder filling refers to insufficient urine volume in the bladder and failure to reach normal filling state.

The bladder is an organ that stores urine. Under normal circumstances, when urine is produced by the kidneys, it will enter the bladder through the ureter and be stored in the bladder. When the urine volume reaches a certain amount, it will stimulate the bladder wall to produce urination reflex and then expel urine from the body. In some cases, poor bladder filling may occur, such as excessive urination, insufficient intake and renal insufficiency. Among them, excessive urination will discharge too much urine stored in the bladder, showing poor filling. Too little water intake may reduce urine production, resulting in poor bladder filling; renal insufficiency may affect urine production, resulting in a decrease in urine in the bladder.
