Urodynamics and Clinical Factors That Are Associated With Bladder Over-sensitivity
Study Details
Study Description
Brief Summary
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.

Detailed Description
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).

Arms and Interventions

| Patients undergoing urodynamic All patients older than 18 who are refered for Urodynamics examination |
Other: IPSS questionnaire
IPSS is an 8 question (7 symptom questions + 1 quality of life question) written screening tool used to screen for, rapidly diagnose, track the symptoms of, and suggest management of patients with lower urinary tract symptoms. It was validated for both genders.

Outcome Measures
Primary Outcome Measures
- Early sensation during the filling phase [During the urodynamic examination]
Bladder oversensitivity (early sensation), a diagnosis made by symptoms and urodynamic investigations. Defined as an increased perceived bladder sensation during bladder filling with specific cystometric findings of: (i) an early first desire to void; (ii) an early strong desire to void, which occurs at low bladder volume; (iii) a low maximum cystometric bladder capacity; no abnormal increases in detrusor pressure.
