A series of 20 patients underwent conventional medium fill cystometry (CMG) and ambulatory monitoring during natural bladder filling (AM). The measurement of voiding pressures by the 2 techniques was compared. The maximum subtracted detrusor contraction pressure recorded during CMG (50 +/- 30 cm H2O) was significantly less than that recorded during AM (86 +/- 35 cm H2O). Voiding pressures during natural filling are greater than those observed during conventional urodynamic studies: this finding may have important implications in the definition of bladder outflow obstruction.
对20例患者进行了常规中等容量膀胱测压法（CMG）和自然膀胱充盈期间的动态监测（AM）。比较了两种技术对排尿压力的测量结果。CMG期间记录的最大减去逼尿肌收缩压（50±30cm H2O）显著低于AM期间记录的（86±35cm H2O）。自然充盈期间的排尿压力大于传统尿动力学研究中观察到的压力：这一发现可能对膀胱出口梗阻的定义具有重要意义。
