Postmicturition dribble (PMD) is a common condition in the male population.
Despite its common occurrence, there are only a few studies on this topic so far. The aim of this study was to investigate possible physiological aspects of PMD.
Seventeen men complaining of PMD and 10 healthy subjects were assessed via uroflometry, IPSS questionnaire, IIEF-5 questionnaire, and an adapted visual analogue scale (VAS) for ejaculation force -(0-10) and the amount of bother concerning PMD (0-10) were completed. In addition to that, a retrograde urethrography at 40 and 60 cm water column as pressure unit to measure the width of the bulbar urethra was performed, and the amount of PMD was measured with an adjusted pad test.
The PMD group showed a significantly worse IPSS score, a lower Qmax rate in uroflowmetry, a worse IIEF-5 score, and a worse VAS score concerning ejaculation force. In both groups, worse IPSS levels correlated with a low bulbar urethral diameter at 40 and 60 cm water column. -Another correlation was found between a high maximum urine flow rate and a larger bulbar urethral diameter at 40 and 60 cm. Both groups showed urine loss after micturition, with no bother (VAS 0) in the control group, whereas the PMD group showed a VAS of 6.
PMD should be regarded as a physiological occurrence in men rather than a disease by itself. Suffering is only to be expected in combination with other lower urinary tract symptoms.
排尿后滴沥（PMD）在男性人群中很常见。
尽管其很常见，但迄今为止关于该主题的研究却很少。本研究的目的是调查PMD可能的生理方面。
通过尿流率测定、国际前列腺症状评分（IPSS）问卷、国际勃起功能指数-5（IIEF-5）问卷以及用于射精力量的改良视觉模拟量表（VAS）（0-10）和关于PMD困扰程度的量表（0-10）对17名主诉有PMD的男性和10名健康受试者进行评估。此外，以40和60厘米水柱作为压力单位进行逆行尿道造影以测量球部尿道宽度，并通过调整后的护垫试验测量PMD量。
PMD组的IPSS评分明显更差，尿流率测定中的最大尿流率（Qmax）更低，IIEF-5评分更差，射精力量的VAS评分也更差。在两组中，较差的IPSS水平与40和60厘米水柱时较低的球部尿道直径相关。还发现最大尿流率高与40和60厘米时较大的球部尿道直径之间存在另一种相关性。两组排尿后均有尿液流失，对照组无困扰（VAS为0），而PMD组的VAS为6。
PMD应被视为男性的一种生理现象，而非一种疾病本身。只有与其他下尿路症状同时出现时才会引起困扰。
