Comparison of urinary incontinence following three different prostate apex disconnection techniques in transurethral thulium laser prostatectomy.

OBJECTIVE: This study investigates the incidence of urinary incontinence following transurethral thulium laser prostatectomy with three different prostate apex disconnection techniques: semi-separation, pre-separation, and post-separation. The findings aim to provide references for clinical treatment. PATIENTS AND METHODS: A retrospective analysis was conducted on 74 patients treated with transurethral thulium laser prostatectomy for prostatic hyperplasia from April 2022 to March 2023. Complete clinical and follow-up data were available for 52 patients. Clinical and follow-up data were collected for these patients. A comparison was made of urinary incontinence following the three different types of prostate apex disconnection in transurethral thulium laser prostatectomy. RESULTS: In this study, the immediate postoperative urinary incontinence rate for transurethral thulium laser prostatectomy was 9.62% (5/52), the short-term incontinence rate was 11.54% (5/52), and the long-term incontinence rate was 9.62% (5/52). The immediate postoperative incontinence rates for semi-separation, pre-separation, and post- separation were 8.33% (1/12), 8.33% (2/24), and 12.5% (2/16), respectively. The short-term incontinence rates for semi-separation, pre-separation, and post-separation were 8.33% (1/12), 8.33% (2/24), and 18.75% (3/16), respectively. The long-term incontinence rates for semi-separation, pre-separation, and post-separation were 8.33% (1/12), 8.33% (2/24), and 12.5% (2/16), respectively. CONCLUSIONS: The incidence of urinary incontinence following transurethral thulium laser prostatectomy was lower with semi-separation and pre-separation compared to post-separation.

[Progress in epidemiological characteristics and surveillance and early warning of dengue fever in China].

Dengue fever is an acute mosquito-borne infectious disease caused by dengue virus and widely spread worldwide. Many factors, such as pathogens, vector organisms, climate, and social environment, affect its transmission and prevalence. The local dengue fever epidemic caused by imported cases in China shows a trend of increasing epidemic latitude and more widespread epidemic areas. However, the traditional monitoring and early warning models of dengue fever mainly focus on researching a single factor and a single area. Establishing a multi-factor forecast and early warning system is urgent to strengthen the early warning capability for the dengue fever epidemic. This paper mainly discusses the epidemic characteristics, the influencing factors, and the surveillance and early warning models of dengue fever in China to provide a reference for the effective prevention and control of dengue fever in China.

[Epidemiological investigation of constipation in urban areas of Hangzhou, China].

Objective: To determine the prevalence and risk factors of constipation in Hangzhou urban areas by analyzing data from a recent epidemiological survey. Methods: From August 2022 to June 2023, a cross-sectional survey was conducted on 43 communities on eight streets in suburbs of Hangzhou, including Wangjiang, Sijiqing, Puyan, Changhe, Ziyang, Xiaoshanchengxiang, Zhuantang, and Banshan. Written questionnaires were filled out face to face by community doctors. The prevalence of constipation was investigated using a combination of the Bristol stool typing method and the Rome IV criteria. The risk factors for constipation were analyzed using multivariate logistic regression analysis. Results: The study cohort comprised 10,479 participants, 5551 of whom were male (53.0%) and 4928 female (47.0%). The overall prevalence of constipation was 10.6% (1107/10,479). The prevalence was 11.0% (613/5551) for male and 10.0% (494/4928) for female participants; this difference is not statistically significant (P>0.05).There were no significant differences in the prevalence of constipation between different categories of body mass index (P>0.05). The prevalence of constipation was highest in individuals aged 70 years and above, accounting for 15.4% (264/1717) of all cases. There were significant differences in the prevalence of constipation between different occupations, marital statuses, and educational levels (P<0.001). Patients with hypertension or diabetes mellitus had a higher prevalence of constipation than those without these conditions, those who had been taking long-term medication had a higher prevalence of constipation than those who did not, parents of children with constipation had a higher prevalence of constipation than those with children who did not have constipation, and there were other significant differences in various variables (P<0.001). Multivariate logistic regression analysis of modifiable factors revealed that eating less fruit (OR=1.284, 95%CI: 1.061-1.553, P=0.010), liking spicy and salty food (OR=1.234, 95%CI: 1.039-1.466, P=0.016), sleeping for too long (OR=1.644, 95%CI: 1.260-2.144, P<0.001), irregular sleep patterns (OR=1.370, 95%CI: 1.127-1.665, P=0.002) and minimal exercise (OR=1.388, 95% CI: 1.168-1.649, P<0.001) were all risk factors for constipation; whereas mix diets (OR=0.709,95%CI:0.608-0.826, P<0.001), meat diets (OR=0.604,95%CI: 0.495-0.736, P<0.001), moderate alcohol consumption (OR=0.659, 95% CI: 0.534-0.812, P<0.001), less or no drinking (OR=0.523, 95% CI: 0.428-0.638, P<0.001), and non-smoking (OR=0.819, 95%CI:0.674-0.995, P<0.001) protected against constipation. We found no association between dietary preferences and the risk of constipation (refined grains: OR=1.147, 95%CI:0.944-1.393, P=0.167; no specific preference: OR=0.935, 95%CI:0.783-1.117, P=0.459). The rate of agreement between self-evaluation of constipation by the respondents and objective criteria was higher for negatives (95.8%) than for positives (38.0%). Conclusion: The prevalence of constipation is relatively high in the urban population of Hangzhou. A good lifestyle and diet can significantly reduce its incidence. There should be more emphasis on preventive education, promotion of prevention of constipation, and advocacy for a healthy lifestyle.

Analysis of risk factors for stone remnants and recurrence after lateral decubitus percutaneous nephrolithotomy.

OBJECTIVE: This study aims to explore the risk factors for stone remnants and recurrence after lateral decubitus percutaneous nephrolithotomy (PCNL), providing insights to enhance the stone-free rate and reduce the stone recurrence rate. PATIENTS AND METHODS: A retrospective analysis was conducted on 356 patients with renal or upper ureteral stones who underwent lateral decubitus PCNL from January 2015 to August 2022. Among them, 271 patients had complete clinical and follow-up data. General clinical information, perioperative data, and follow-up data were collected. Univariate and multivariate logistic regression analyses were performed to identify risk factors for stone remnants and recurrence after lateral decubitus PCNL. RESULTS: The stone-free rate after lateral decubitus PCNL was 88.6% (195/271), and the stone recurrence rate within three years was 28.1% (76/271). Stone size (p<0.001) and stone co-infection (p=0.047) were identified as independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones (p=0.003) were an independent risk factor for stone recurrence after lateral decubitus PCNL. CONCLUSIONS: Stone size and stone co-infection are independent risk factors for stone remnants after lateral decubitus PCNL. Multiple stones are an independent risk factor for stone recurrence after lateral decubitus PCNL.
