Traces: making sense of urodynamics testing--Part 9: Evaluation of sensations detrusor response to bladder filling.

Part 9 of the Traces series continues the discussion of how urodynamic clinicians generate usable data from a filling cystometrogram. This article focuses on the question: "What is the detrusor's response to bladder filling?" Answering this question requires the clinician to identify and differentiate detrusor contractions from abdominal events, artifacts, or low bladder wall compliance; documentation of the volume of the contraction; and assessment of its clinical relevance as an overactive or subclinical detrusor contraction.
