INTRODUCTION: In Korea, although male sexual problems have been relatively well addressed, few surveys have been conducted on female sexual dysfunction (FSD) in the general population. In the present study, we investigated the prevalence and identified the risk factors of sexual dysfunction in young Korean women. AIM: To evaluate the prevalence and to identify the risk factors of FSD in young Korean women. METHODS: A total of 47,000 women were initially approached. All received an e-mail request

AIM: To investigate the reasons for discontinuations of sildenafil after the successful restoration of erectile function. METHODS: One hundred fifty six patients, whose scores of erectile function domain of the 15-item International Index of Erectile Function (IIEF) increased to 26 or more after sildenafil medication, were included in this study. Six-months after the first sildenafil prescription, compliance to medication and the reason for discontinuity were reviewed by chart or surveyed by tel

Premature ejaculation (PE) is suspected to be the most prevalent male sexual complaint, and the prevalence of PE is considerably high also in the younger generation. We investigated the PE prevalence based on the Diagnostic and Statistical Manual of Mental Disorders (4th ed text revision; DSM-IV-TR) definition and the risk factors of PE in Korean young men via Internet survey. Subjects (n = 3980) aged from 20 to 59, who performed sexual intercourse more than once a month during the past 6 months

INTRODUCTION: The psychological impacts of premature ejaculation (PE), which include guilt, anxiety, and distress, have been well established in Western countries. However, in Asia, although a substantial number of epidemiological studies have surveyed the prevalence of PE, researchers have not thoroughly investigated the relationship between PE and depression, or have defined PE properly. AIM: We studied the association between PE and depression and other psychological disturbances, in a Korean

OBJECTIVE: To investigate the influences of lifestyle and metabolic syndrome (MetS) on the prevalence of benign prostatic hyperplasia (BPH) requiring treatment using a large historical cohort. PATIENTS AND METHODS: This study included 130 454 men selected from the National Health Information Database of the National Health Insurance Service in South Korea. Men were divided into the two groups according to the presence of MetS. A generalised estimating equation was used to assess the predictors o

BACKGROUND: This study evaluated the effects of a 'centralized intensive education system' (CIES) in terms of acquiring a proper clean intermittent self-catheterization (CISC) technique by patients with voiding dysfunction. METHODS: Between March 2002 and March 2003, we prospectively and consecutively enrolled 132 hospitalized patients who learnt and started CISC for the first time due to voiding dysfunction. Patients were enrolled either of two groups (the CIES group vs the 'individualized ward

The latest technical improvements in the surgical armamentarium are remarkable. In particular, advancements in the urologic field are so exceptional that we could observe the flare-up of robot-assisted laparoscopic radical prostatectomy for prostate cancer and laser prostatectomy for benign prostatic hyperplasia (BPH). Photoselective vaporization of the prostate (PVP) and holmium laser prostatectomy are the most generalized options for laser surgery of BPH, and both modalities have shown good po

AIMS: To determine the influence of preoperative detrusor underactivity (DU) on serial long-term outcomes of HPS/PVP or HoLEP for LUTS/BPH, and to compare the influence between the two surgeries. METHODS: A total of 382 men, who underwent 120W-HPS/PVP or HoLEP for LUTS/BPH and for whom 36-month follow-up data were available, were classified into four groups: HPS with DU (n = 145), HPS without DU (n = 44), HoLEP with DU (n = 105), and HoLEP without DU (n = 88). DU was defined as bladder contracti

INTRODUCTION: Because the prevalence of premature ejaculation (PE) may change with time, few studies have been conducted over a 10-year time interval. AIM: A 10-year time interval survey to determine whether there was a change in the prevalence of self-identified PE and PE defined on the basis of an estimated intravaginal ejaculation latency time of <3 minutes in adult Korean men, even after adjusting for various sociocultural factors. METHODS: We sent an e-mail to the panels registered in the s
