Post Micturition Dribble

The goal of this clinical trial is to evaluate the effect of pelvic floor muscle exercises on primary post-micturition dribbling (PMD) in male patients aged 18 to 40 years. The main questions it aims to answer are: 1. Does pelvic floor muscle training reduce the severity and frequency of PMD as measured by the Hallym Post-Micturition Dribble Questionnaire (HPMDQ)? 2. Does pelvic floor muscle training reduce the amount of post-void residual urine as measured by a post-voiding pad test? Researchers will compare patients undergoing pelvic floor muscle training (Group A) with those performing non-targeted exercises (Group B) to see if targeted pelvic floor training is more effective in managing PMD symptoms and reducing urine leakage. Participants will: * Undergo random assignment to either pelvic floor muscle training or non-targeted exercise for 12 weeks * Complete baseline and follow-up assessments including: * Medical history and physical exam * Urine analysis and post-void residual measurement * International Prostate Symptom Score (IPSS) * Post-voiding pad test * Hallym Post-Micturition Dribble Questionnaire (HPMDQ)
