Terminal dribbling is one of the lower urinary tract symptoms (LUTS) that has not been widely studied. The aim of this study was to investigate the associations between terminal dribbling (TD) and other parameters such as International Prostate Symptom Score (IPSS) and intravesical prostatic protrusion (IPP).


Medical records of male patients with LUTS aged 40 years and older were prospectively collected. Data regarding TD defined by the International Continence Society standardization subcommittee, IPSS, prostate-specific antigen, total prostate volume, and IPP on transrectal ultrasonography were obtained. TD was confirmed by the subsequent uroflowmetry (uroflowmetry-confirmed TD). Logistic regression analysis was performed to identify the parameters affecting TD and uroflowmetry-confirmed TD.


Among the 578 men, 226 patients (39.1 %) complained of TD and 157 patients (27.2 %) had objective findings of TD on uroflowmetry. In the logistic regression analysis, IPSS voiding subscore were correlated with TD (Odds ratio 1.06). In addition, IPP was the only significant risk factor for uroflowmetry-confirmed TD (Odds ratio 2.83). Each question of IPSS is not correlated with TD or uroflowmetry-confirmed TD.


While the symptom of TD is well correlated with IPSS voiding subscore, objective evidence of TD on uroflowmetry had strong correlation with IPP. TD should be investigated further to reveal its clinical impact and guide a proper management.
