Cystometry, or cystometrogram, with a pressure flow study is part of urodynamic testing (or UDS). These tests measure how well the bladder functions. They help diagnose problems related to urine control. These can be incontinence, difficulty emptying the bladder, overactive bladder, obstructions or frequent infections.

Cystometry is used to measure how much urine the bladder can hold. It also measures pressure inside the bladder, and how full it is when you have the urge to go.
