The relationship between hyperuricemia (HUA) and erectile dysfunction (ED) remains inadequately understood. Given that HUA is often associated with various metabolic disorders, this study aims to explore the multivariate linear impacts of metabolic parameters on erectile function in ED patients with HUA. A cross-sectional analysis was conducted involving 514 ED patients with HUA in the Department of Andrology, Jiangsu Province Hospital of Chinese Medicine (Nanjing, China), aged 18 to 60 years. General demographic information, medical history, and laboratory results were collected to assess metabolic disturbances. Sexual function was evaluated using the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire. Based on univariate analysis, variables associated with IIEF-5 scores were identified, and the correlations between them were evaluated. The effects of these variables on IIEF-5 scores were further explored by multiple linear regression models. Fasting plasma glucose ( β = -0.628, P < 0.001), uric acid ( β = -0.552, P < 0.001), triglycerides ( β = -0.088, P = 0.047), low-density lipoprotein cholesterol ( β = -0.164, P = 0.027), glycated hemoglobin (HbA1c; β = -0.562, P = 0.012), and smoking history ( β = -0.074, P = 0.037) exhibited significant negative impacts on erectile function. The coefficient of determination ( R ²) for the model was 0.239, and the adjusted R ² was 0.230, indicating overall statistical significance ( F -statistic = 26.52, P < 0.001). Metabolic parameters play a crucial role in the development of ED. Maintaining normal metabolic indices may aid in the prevention and improvement of erectile function in ED patients with HUA.

Objective To evaluate the safety and feasibility of single-port laparoscopic surgery (SPLS) for chronic appendicitis.Methods Data of patients who had undergone either conventional threeport surgery (n =58) or SPLS (n =63) for chronic appendicitis between January 2010 and November 2012 were analyzed retrospectively.The short-term outcomes of these 2 operative modalities were compared.Results The overall satisfaction score of SPLS group was significantly higher than that of the three-port group (4.5 ±0.7) vs.(3.0 ±0.6),t =13.50,P =0.00,there was less frequent use of parenteral narcotics in SPLS patients (1.2 ± 0.5) vs.(2.1 ± 0.7) times,t =-8.25,P =0.00,length of operation time was the same in SPLS group (40 ± 10) vs.(37 ±9) minutes,t =1.94,P =0.055.There was not different in postoperative recovery (1.4 ± 0.6) vs.(1.6 ± 0.7) d,t =-1.82,P =0.072,nor different in perioperative complications and intraoperative blood loss between groups (12 ± 6) vs.(13 ± 6) ml,t =-1.50,P =0.137.Conclusions SPLS is both safe and feasible in the treatment of chronic appendicitis.
