The ureteric pressure profile in the normal and pathologic ureter was studied. A 3F ureteric catheter was introduced through the ureteric orifice up to the mid-renal pelvis, and was connected to a pressure transducer. The catheter was pulled down to the urinary bladder and during withdrawal the pressures in the renal pelvis, uretero-pelvic junction (UPJ), ureter, ureterovesical junction (UVJ) and urinary bladder were recorded. The normal ureteric pressure profile started with a peak rise at the UPJ followed by a drop and fluctuations representing the peristaltic waves, and ended with a peak rise at the UVJ. The strictured moderately dilated ureter showed peristaltic waves with irregular rhythm and pressure amplitude, a condition we call "ureteroarryhthmia". The hugely dilated ureter exhibited no waves, i.e. a "silent" profile. The refluxing ureter with normal caliber showed an ureteroarrhythmic pressure profile, while the dilated ureter exhibited either a ureteroarrhythmic or a silent pattern. The study could define a characteristic profilometric pattern for the normal ureter. Two pathologic patterns could be identified: ureteroarrhythmic and silent. Ureteric pressure profilometry is suggested acts as a diagnostic tool in the various pathologic conditions of the ureter.
研究了正常输尿管和病理状态下输尿管的压力分布情况。通过输尿管口插入一根3F输尿管导管直至肾盂中部，并连接到压力传感器。将导管向下拉至膀胱，在回撤过程中记录肾盂、输尿管肾盂连接处（UPJ）、输尿管、输尿管膀胱连接处（UVJ）和膀胱的压力。正常输尿管压力分布始于UPJ处的压力峰值升高，随后下降并伴有波动，代表蠕动波，最后在UVJ处出现压力峰值升高。中度扩张并伴有狭窄的输尿管显示出节律和压力幅度不规则的蠕动波，我们将这种情况称为“输尿管心律失常”。极度扩张的输尿管未显示出波动，即呈现“无波”状态。管径正常的反流输尿管显示出输尿管心律失常的压力分布，而扩张的输尿管则呈现输尿管心律失常或无波模式。该研究能够确定正常输尿管的特征性压力分布模式。可识别出两种病理模式：输尿管心律失常和无波。输尿管压力轮廓测定法被认为可作为输尿管各种病理状况的诊断工具。
