Urodynamic examination evaluates storage and empting phases of the urinary bladder. It enables the clinician to correlate physiologic findings to patients' complains. The data gathered during the examination divided to storage and empting.

During the storage phase, bladder sensation is measured while the bladder is filled with sterile water. During years of practice, we noticed that early sensation (bladder over-sensitivity) is occasionally associated with bladder outlet obstruction (as demonstrated in the emptying phase of the examination.

The study includes patients who were referred to Urodynamics examination due to lower urinary tract symptoms. There is no actual intervention during the examination. Though, patients are asked to fill an International prostate symptom score (IPSS-questionnaires).
