In February 2011, the Korean Society for Sexual Medicine and Andrology (KSSMA) realized the necessity of developing a guideline on erectile dysfunction (ED) appropriate for the local context, and established a committee for the development of a guideline on ED. As many international guidelines based on objective evidence are available, the committee decided to adapt these guidelines for local needs instead of developing a new guideline. Considering the extensive research activities on ED in Korea, data with a high level of evidence among those reported by Korean researchers have been collected and included in the guideline development process. The latest KSSMA guideline on ED has been developed for urologists. The KSSMA hopes that this guideline will help urologists in clinical practice.

PurposeIt has been reported that varicocele is found less frequently in obese men. Accordingly, we evaluated varicocele patients and statistically analyzed the correlation between varicocele and somatometric parameters.Materials and MethodsA total of 211 patients underwent surgery for varicoceles. All patients underwent history taking, physical examination, and scrotal ultrasound to determine the presence and severity of varicocele. An age-matched control group consisted of 102 patients who were found not to have varicocele according to physical examinations and scrotal ultrasound. The age, weight, height, and body mass index (BMI) of the two groups were compared. The statistical analyses were performed by use of PASW Statistics ver. 18.0. A p-value of less than 0.05 was used for statistical significance.ResultsIn the varicocele group, the mean age, height, weight, and BMI were 29.42±14.01 years, 168.53±9.97 cm, 62.14±13.17 kg, and 21.66±3.21 kg/m2, respectively. The distribution of varicocele grade was as follows: 103 (48.8%) grade III, 72 (34.1%) grade II, and 36 (17.1%) grade I. In the control group, the mean age, height, weight, and BMI were 30.83±17.31 years, 161.93±19.83 cm, 64.69±17.86 kg, and 24.04±3.64 kg/m2, respectively. Analyzing these data specifically in adolescents, they showed significant differences in age, height, and BMI (p=0.000, p=0.000, and p=0.004, respectively) between two groups. There were no significant differences in somatometric parameters between patients with different grades of varicocele.ConclusionsOur results showed that patients with varicoceles were significantly taller and had a lower BMI than did patients without varicoceles, especially among adolescents. Carefully designed future studies may be needed.

PurposeTo investigate the incidence and predictive factors associated with the development of chronic kidney disease (CKD) in patients undergoing curative surgery for renal cell carcinoma.Materials and MethodsFrom 2003 to 2010, we retrospectively investigated 108 patients undergoing partial nephrectomy or radical nephrectomy (RN) for renal tumors with a preoperative glomerular filtration rate (GFR)≥60. The GFR was calculated by use of the four-variable modification of diet in renal disease (MDRD) formula. CKD was defined as an estimated GFR (eGFR) less than 60 mL/min per 1.73 m2. Demographic and clinicopathologic parameters were evaluated by using the chi-square and Student t-tests and multivariate regression analysis to determine the variables independently associated with the development of postoperative CKD.ResultsOf the 108 patients without preoperative CKD, CKD developed in 43 patients (39.8%). In the analysis of clinical factors between patients with and those without CKD development, gender, body mass index, diabetes mellitus, hypertension, and tumor size were not significant clinical factors. Statistical significance for CKD development was found for age of 60 years or greater (p=0.013), decreased preoperative eGFR (p<0.001), and RN group (p<0.001). In the multivariate analysis, decreased preoperative eGFR (p=0.001) and RN group (p=0.002) were significant independent predictors.ConclusionsThe results of our study show that decreased preoperative renal function and RN were significant independent predictors of postoperative CKD. In patients who had a relatively decreased preoperative eGFR, especially when estimated by use of the MDRD formula, nephron-sparing surgery should be considered for the treatment of small renal tumors.

[Purpose] The purpose of this study was to translate the Trunk Control Measurement Scale into a Korean version and to analyze the intra- and inter-rater reliability. [Subjects and Methods] Fifteen children with spastic cerebral palsy and four physical therapists with over 10 years of clinical experience participated in this study. A Korean-American physical therapist translated the trunk control measurement scale from English into a Korean version. Four physical therapists viewed the video data of 15 children and scored each child’s trunk control measurement scale performance on seven separate days. Four testers analyzed the test-retest reliability and inter-rater reliability using the intra-class correlation coefficient. [Results] Intra-class correlation coefficients for test-retest and inter-rater reliability for the Korean trunk control measurement scale showed significantly high reliability in all testers and sublevels. [Conclusion] The Korean version of the measurement scale is a reliable and suitable instrument for assessing trunk control in individuals with cerebral palsy in Korea.
