Fifteen patients presenting with postmicturition dribbling as their only symptom were studied in the urodynamic laboratory. Seven of these patients had no urodynamic abnormality but left a significant bulbar residue after micturition. Five patients had normal detrusor function but failed to milk back contrast from the prostatic urethra during voluntary interruption of the steam. Two of these also had a small amount of bulbar residue. The remaining three had unstable detrusor function. One had classic bladder neck obstruction. One had a bulbar residue and the other failed to milk back properly. Despite the various mechanisms for postmicturition dribble, the management is the same in all cases. The patient is instructed to press the bulbar urethra manually in the perineum after micturition and evacuate the residue, and symptomatic relief is almost always obtained. Urodynamic studies in these patients are not justified unless this maneuver fails to alleviate the symptoms.
在尿动力学实验室对15例仅以排尿后滴沥为唯一症状的患者进行了研究。其中7例患者没有尿动力学异常，但排尿后球部有大量残余尿。5例患者逼尿肌功能正常，但在自主中断排尿时未能从前列腺尿道挤出造影剂。其中2例也有少量球部残余尿。其余3例有逼尿肌功能不稳定。1例有典型的膀胱颈梗阻。1例有球部残余尿，另1例未能正确挤出造影剂。尽管排尿后滴沥有多种机制，但所有病例的处理方法相同。指导患者排尿后在会阴部手动按压球部尿道并排出残余尿，几乎总能获得症状缓解。除非这种方法不能缓解症状，否则对这些患者进行尿动力学检查是不合理的。
