Pressure-flow studies consist of simultaneously measuring urine flow rate and the detrusor pressure required to achieve this flow rate. It is the reference test for the diagnosis of bladder neck obstruction, characterized by the combination of high detrusor pressure and low urine flow rate. Pressure-flow studies are essentially indicated in the presence of voiding disorders of undetermined aetiology, with a discordance between clinical history, clinical examination and uroflowmetry, or in the presence of neurological disease associated with benign prostatic hyperplasia (BPH), or when surgical treatment of BPH is associated with particular morbidity in order to document bladder neck obstruction.
压力-流率研究包括同时测量尿流率以及产生该尿流率所需的逼尿肌压力。它是诊断膀胱颈梗阻的参考性检查，其特征为逼尿肌压力高且尿流率低。压力-流率研究主要适用于病因不明的排尿障碍，临床表现、体格检查与尿流率测定结果不一致时，或存在与良性前列腺增生（BPH）相关的神经疾病时，又或者当BPH的手术治疗伴有特殊并发症时，用于证实膀胱颈梗阻。
