We evaluate the relationship among post-voiding residual urine volume, bladder outlet obstruction and maximum detrusor contractility power.
We investigated urodynamically and retrospectively 242 elderly men with various grades of bladder outlet obstruction and symptoms.
Residual urine predominantly correlated with bladder outlet obstruction and not with maximum detrusor contractility power. Maximum detrusor contractility power showed significant positive correlation with bladder outlet obstruction. Urodynamically, the detrusor compensates for bladder outlet obstruction with elevated maximum detrusor contractility power. Decay of contraction during micturition however, hampers effective emptying.
Maximum detrusor contractility power limits for normal detrusor contractility must be related to bladder outlet obstruction grade. Based on the results of our analysis, new limits showing improved correlation with complete emptying were derived.
我们评估排尿后残余尿量、膀胱出口梗阻和最大逼尿肌收缩力之间的关系。
我们对242例有不同程度膀胱出口梗阻和症状的老年男性进行了尿动力学检查和回顾性研究。
残余尿主要与膀胱出口梗阻相关，而与最大逼尿肌收缩力无关。最大逼尿肌收缩力与膀胱出口梗阻呈显著正相关。在尿动力学方面，逼尿肌通过提高最大逼尿肌收缩力来代偿膀胱出口梗阻。然而，排尿过程中收缩力的衰减会妨碍有效排空。
正常逼尿肌收缩力的最大逼尿肌收缩力限度必须与膀胱出口梗阻程度相关。基于我们的分析结果，得出了与完全排空相关性更好的新限度。
