Our multicenter, patient-blinded/evaluator-blinded, randomized comparative trial was performed for 18 months after the single injection of fillers.

A Comparison Between Hyaluronic Acid and Polylactic Acid Filler Injections for Temporary Penile Augmentation in Patients with Small Penis Syndrome: A Multicenter, Patient/Evaluator-Blind, Comparative, Randomized Trial.

Introduction: There are only a few studies on the clinical utility of filler injections for penile augmentation (PA) in patients with small penis syndrome (SPS), which is a type of anxiety or body dysmorphic disorder, not a true micropenis.

Aim: To compare the clinical outcomes of hyaluronic acid (HA) with polylactic acid (PLA) filler injection for temporary PA in patients with SPS.

Methods: Our prospective, patient/evaluator-blind, comparative, randomized, non-inferiority trial consisted of a single filler injection and a 24-week post-injection period.

Development and validation of a symptom assessment tool for postmicturition dribble: A prospective, multicenter, observational study in Korea.

Objectives: Postmicturition dribble (PMD) is a very common symptom in males with lower urinary tract symptoms (LUTS) worldwide, but there is no adequate questionnaire to assess it. Therefore, we developed a questionnaire named the Hallym Post Micturition Dribble Questionnaire (HPMDQ) to assess PMD, and the aim of this study is to validate it.

Methods: A series of consecutive male patients newly diagnosed with LUTS and over 40 years of age who visited any of 5 medical institutions were included.

Effect of tadalafil 5 mg on post-micturition dribble in men with lower urinary tract symptoms: a multicentre, double-blind, randomized, placebo-controlled trial.

Objectives: To compare the effects of taking tadalafil 5 mg and placebo once daily on post-micturition dribble (PMD) in men with lower urinary tract symptoms (LUTS).

Patients And Methods: Our prospective, randomized, double-blind, placebo-controlled, multicentre trial enrolled 102 men with PMD and other LUTS. PMD was assessed using the Hallym Post-Micturition Dribble Questionnaire (HPMDQ) and according to PMD volume.

A current perspective on post-micturition dribble in males.

Post-micturition dribble (PMD) is the involuntary loss of urine immediately after urination. It is classified as a post-micturition symptom and is more common in males. Traditionally, PMD has been considered to be part of the aging process, to have a low prevalence, and to be less bothersome than other lower urinary tract symptoms (LUTS).

Aim: To compare the efficacy and safety between hyaluronic acid (HA) and polylactic acid (PLA) filler injection for PA.

Effect of udenafil administration on postmicturition dribbling in men: a prospective, multicenter, double-blind, placebo-controlled, randomized clinical study.

Purpose: Postmicturition dribbling (PMD) is a stressful symptom in middle-aged men characterized by urinary leakage after the completion of normal voiding. Appropriate treatments have not yet been introduced. This study assessed the efficacy of treatment of PMD with 75 mg udenafil daily.

Choroidal Thickness Analysis in Patients with Erectile Dysfunction.

Purpose: To investigate the morphological features of choroidal vasculature in patients with erectile dysfunction (ED) by analyzing choroidal thickness using optical coherence tomography.

Is A Combination of Antibiotics and Non-Steroidal Anti-Inflammatory Drugs More Beneficial Than Antibiotic Monotherapy For The Treatment of Female Acute Uncomplicated Cystitis? A Randomized Controlled Pilot Study.

Purpose: To compare the efficacy of non-steroidal anti-inflammatory drugs (NSAIDs) combination therapy to single-agent antibiotic therapy for the resolution of symptoms during two restricted activity days in patients with acute uncomplicated cystitis (AUC)Materials and Methods: We performed a prospective, randomized control pilot study. A total of 55 patients were enrolled. Group I (n=28) was treated with cepodoxime (100 mg twice per day), and Group II (n=27) was treated with cepodoxime (100 mg) and aceclofenac (100 mg) twice per day; both groups were treated for three days.

Postmicturition Dribble Is Associated with Erectile Dysfunction in Middle-Aged and Older Men with Lower Urinary Tract Symptoms.

Purpose: Lower urinary tract symptoms (LUTS) are correlated with erectile dysfunction (ED), but research on whether postmicturition dribble (PMD) is related to ED is limited. We assessed the correlation between PMD and ED in middle-aged and older Korean men with LUTS.

Materials And Methods: In our prospective, cross-sectional, observational, multicenter study, we enrolled 205 men (age >40 years) with LUTS.
