Bladder Filling and Storage: “(Involuntary) Contractions”

Urodynamics (UDS) is the dynamic study of the storage and evacuation of urine. Its role is to provide the clinician with information about a patient’s lower urinary tract function. Ideally, the patient’s symptoms are reproduced during the study to provide objective measurements which correlate with the patient’s symptoms. UDS should be considered as an adjunct to a detailed history and physical exam to better characterize the clinical picture and facilitate optimal treatment planning. An important portion of the UDS is the bladder filling and storage phase. Involuntary detrusor contractions (IDCs) may occur during this portion of the study and may provide insight into the pathophysiology of the patient’s complaints. This chapter will focus on the different UDS manifestations of IDCs by investigating the UDS tracings of neurogenic and idiopathic detrusor overactivity, stress-induced overactivity, phasic overactivity, detrusor overactivity incontinence, detrusor after-contractions, and terminal detrusor overactivity.
