Purpose To investigate the efficacy, safety, and tolerability of oro-dispersible film (ODF) formulation of mirodenafil 50 mg and 100 mg for the treatment of patients with erectile dysfunction (ED) in Korea. Materials and methods A multicenter, randomized, double-blind, placebo-controlled, parallel-group study of 129 subjects was performed. Subjects were randomized to either placebo or mirodenafil ODF 50 mg or 100 mg to be taken in an "on demand" manner for 8 weeks. The primary efficacy variable was the International Index of Erectile Dysfunction (IIEF)-5 questionnaire. The secondary efficacy variables comprised Sexual Encounter Profile questions 2 and 3 (SEP2 and SEP3), the Global Assessment Question (GAQ), and the Life Satisfaction Checklist (LSC). Results IIEF-5 was significantly increased in all groups after treatment. However, compared to the placebo group, only the mirodenafil ODF 100 mg group showed a significant difference. SEP2 and SEP3 were increased in both mirodenafil groups; however, the increase was not statistically significant for SEP2. In terms of GAQ and LSC, the mirodenafil ODF groups showed significant increases compared with the baseline. Most treatment-associated adverse events were mild and resolved spontaneously. Conclusions Mirodenafil ODF is an effective and well-tolerated agent for the treatment of patients with ED in Korea.

Purpose The purpose of this study was to evaluate the efficacy of treatment in patients with non-bothering nocturia. Materials and methods In this prospective multicenter study, patients who visited hospitals for treatment of voiding symptoms were enrolled. Inclusion criteria were: 1) men >45 years, and 2) nocturia ≥2 confirmed by a three-day voiding diary. Subjects were divided into non-bothering and bothering groups based on International Consultation on Incontinence Questionnaire Nocturia (ICIQ-N) question 2b. Changes in voiding symptoms, frequency of nocturia, and bothersomeness were evaluated with international prostate symptom score (IPSS), ICIQ-N, and three-day voiding diary at 4 and 12 weeks after treatment. Results A total of 48 patients in the non-bothering nocturia group and 50 patients in the bothering nocturia group who completed the 12-week treatment were analyzed. The total IPSS was decreased by 5.8 in the non-bothering group and 5.2 in the bothering group. There was no significant difference in decrease of IPSS between the two groups. Both groups showed significant reduction in discomfort of nocturia. The ICIQ-N 2b score decreased from 3.9 to 2.7 (p=0.01) in the non-bothering group and from 6.9 to 4.6 (p=0.02) in the bothering group. The number of nocturia episodes was significantly decreased in both groups. Conclusions Regardless of discomfort associated with nocturia, both groups showed significant improvement in nocturia-related discomfort and voiding symptoms. These results suggest that patients with nocturia who were unaware of its discomfort benefited from treatment.

Purpose: Though prompt diagnosis to minimize symptom duration (SD) is highly associated with organ salvage in cases of testicular torsion (TT), SD is subjective and hard to determine. We thus investigated the clinical implications of systemic in-flammatory responses (SIRs) as potential surrogates of SD to improve testis survival. Materials and Methods: Sixty men with TT that underwent immediate operation among orchiectomy and orchiopexy follow-ing a visit to a single emergency department were retrospectively enrolled. Mandatory laboratory tests conducted included neutrophil, lymphocyte, and platelet counts. Results: Mean age and SD was 15.7±3.7 years and 8.27±4.98 hours, respectively. Thirty-eight (63.3%) underwent orchiec-tomy and the remaining 22 underwent orchiopexy. Leukocytosis (p=0.001) and neutrophil-lymphocyte ratio (NLR, p

Purpose: To evaluate the actual impact of testosterone replacement therapy (TRT) on patients with lower urinary tract symptom (LUTS), without benign prostate hyperplasia (BPH) medication. Materials and Methods: Two hundreds forty-six patients underwent TRT using intramuscular injection of 3 months bases injection of testosterone 100 mg undecanoate over a year. Among them, 17 patients had moderate LUTS with a maximal flow rate of at least 10 ml/s but did not take any BPH-specific medication during TRT. The changes in prostate specific antigen (PSA), International Prostate Symptom Score (IPSS), and uroflowmetery were measured before and after TRT. Results: After TRT, PSA remained unchanged after a year of treatment (p=0.078). Compared with their counterparts (n=229), the patients without BPH medication had similar baseline prostate characteristics in all variables, including prostate volume, IPSS, maximal flow rate, voiding volume, and PSA, except the median amount of residual urine, which was higher in the patients without BPH medication (21 ml vs. 10 ml). In the no-BPH medication group, the total IPSS score was decreased significantly (p=0.028), both in storage symptoms (questionnaire 2, 4, 7) and voiding symptoms (questionnaire 1, 3, 5, 6), while the maximal flow rate and residual urine amount remained unchanged after a year of TRT. During the median follow up of 15.1 months, no patients experienced urinary retention, BPH-related surgery, or admission for urinary tract infection. Conclusions: Over a year of TRT for the no-BPH medication patients with moderate LUTS and maintained a relatively high maximal flow rate and improved both storage and voiding symptoms, without the clinical progression of BPH or rising PSA.

Purpose: According to previous studies, the prevalence of premature ejaculation (PE) in Korea ranges from 11.3% to 33%. However, the actual practice patterns in managing patients with PE is not well known. In this study, we have endeavored to determine how contemporary urologists in Korea manage patients with PE. Materials and Methods: The e-mailing list was obtained from the Korean Urological Association Registry of Physicians. A specifically designed questionnaire was e-mailed to the 2,421 urologists in Korea from May 2012 to August 2012. Results: Urologists in Korea diagnosed PE using various criteria: the definition of the International Society for Sexual Medicine (63.4%), Diagnostic and Statistical Manual of Mental Disorders (43.8%), International Statistical Classification of Disease, 10th edition (61.7%), or perceptional self-diagnosis by the patient himself (23.5%). A brief self-administered questionnaire, the Premature Ejaculation Diagnostic Tool, was used by only 42.5% of the urologists. Selective-serotonin reuptake inhibitor (SSRI) therapy was the main treatment modality (91.5%) for PE patients. 40.2% of the urologists used phosphodiesterase type 5 inhibitors, 47.6% behavior therapy, and 53.7% local anesthetics. Further, 286 (54.3%) urologists managed PE patients with a surgical modality such as selective dorsal neurotomy (SDN). Conclusions: A majority of Korean urologists diagnose PE by a multidimensional approach using various diagnostic tools. Most urologists believe that medical treatment with an SSRI is effective in the management of PE. At the same time, surgical treatment such as SDN also investigated as one of major treatment modality despite the lack of scientific evidence.

Cystic lymphangiomas are a benign tumor caused by lymphatic malformation. They are normally seen in the head and neck region and very rarely occur in the scrotum. We report a rare case of a 20-year-old man who presented with a gradually enlarging, painful scrotal mass which was identified ultrasonographically and histologically as a scrotal cystic lymphangioma and treated by surgical excision. 󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏

Purpose: We aimed to elucidate the prevalence of urologic disease in young men by reviewing the results of military conscription examinations in the Republic of Korea. Materials and Methods: The results of 615,382 conscription examinations undertaken by the military manpower administration offices in Seoul, Korea from January, 2006 to December, 2007 were reviewed. The physical examinations were conducted based on the Ministry of National Defense implementing ordinance No. 590. Results: Twenty eight hundred fifty-three (0.46%) examinees were found to have urologic diseases, among which urinary tract infection was the most frequent (0.16%) single disease entity, followed by testicular absence (0.12%), single kidney (0.05%), varicocele (0.04%), urolithiais (0.03%), and cryptorchidism (0.01%). Among the 16 examinees with penile amputation, 15 had been surgically amputated due to gender identity problems. Conclusions: With modifications of the Korean conscription examination and long-term evaluation, its results could help elucidate the prevalence of urologic diseases in young males in Korea. 󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏󰠏
