Multichannel urodynamic studies in men with benign prostatic hyperplasia. Indications and interpretation.
Recent studies suggest that clinical "prostatism" encompasses at least four conditions that may be present singly or in combination: prostatic urethral obstruction, impaired detrusor contractility, detrusor instability, and sensory urgency. In addition, primary vesical neck obstruction may be present in the absence of benign prostatic hyperplasia (BPH). Thus, the purpose of diagnostic evaluation in men with BPH is to identify precisely the pathophysiology of the patient's symptoms so that rational therapy can be selected.
