Objective To evaluate the efficacy and safety of 450 nm blue laser vaporization enucleation of the prostate in the treatment of benign prostatic hyperplasia(BPH)complicated with urinary retention, so as to promote its clinical application. Methods A retrospective analysis was conducted on the clinical data of 60 patients with BPH and urinary retention who underwent 450 nm blue laser vaporization enucleation of the prostate in our hospital during Feb. 2023 and Apr. 2024. All patients had urinary catheters indwelt preoperatively due to urinary retention. The perioperative indicators and complications were recorded. The maximum urinary flow rate(Qmax), postvoid residual(PVR), international prostate symptom score(IPSS), and quality of life score(QoL)were compared before surgery and 3 months after surgery. Results All procedures were completed successfully without conversion to transurethral resection of the prostate(TURP). No cases of severe intraoperative bleeding or transfusion were reported. The average operation time was(60.5±21.5)min, postoperative hemoglobin reduction(3.2±0.8)g/L, catheterization time(3.1±0.4)days, and hospital stay(3.2±0.4)days. No bladder perforation or urethral injury occurred. At 3 months postoperatively, Qmax [(19.2±4.9)mL/s vs.(3.5±2.3)mL/s], PVR [(50.8±20.1)mL vs.(369.2±163.2)mL], IPSS [(9.7±0.9)vs.(21.8±3.2)], and QoL [(1.4±0.5)vs.(4.9±0.1)]were significantly improved compared with preoperative values(P＜0.001). Urinary retention occurred in 2 patients after catheter removal on postoperative day 3, which was resolved one week after re-catheterization. Conclusion The 450 nm blue laser vaporization enucleation of the prostate is a safe and effective treatment for BPH complicated with urinary retention. It can significantly improve the short-term voiding function and quality of life with a low incidence of postoperative complications, demonstrating promising potential for clinical adoption.

Objective:To evaluate the quality of information on autoimmune liver disease in videos on the TikTok short video platform.Methods:The keyword "autoimmune liver disease" was used to search the top 200 videos on TikTok in the default sorting order. Using the DISCERN video quality assessment tool and the structured content integrity evaluation tool, we assessed the quality of the information in each video in relation to the pertinent disease guidelines. Furthermore, we investigated any relationships between the quality of the videos and their characteristics (likes, comments, retweets, days and duration of uploading).Results:A total of 140 videos were included, 96.4% of which were provided by medical professionals. The content completeness scores for each dimension were as follows: definition, 1.0 (0.0, 1.0); symptoms, 0.0 (0.0, 1.0); risk factors, 0.0 (0.0, 0.5); assessment, 0.5 (0.0, 1.5); management, 0.5 (0.0, 1.0); and outcome, 0.0 (0.0, 1.0). Furthermore, 91.4% of videos with DISCERN scores of ≤50 were of "fair" quality or below. Additionally, the difference in DISCERN scores between videos from different publishers was not statistically significant ( P>0.05). The number of likes, comments, favorites, retweets, and video duration had a strong positive correlation with the overall DISCERN score ( r=0.17, 0.18, 0.25, 0.26, 0.44, all P<0.05). Conclusions:The overall quality of videos related to autoimmune liver disease on the TikTok video platform is low. Therefore, publishers should focus on the comprehensiveness and accuracy of the information. Additionally, the TikTok platform should optimize its video review mechanism to provide the public with more accurate and reliable health information.

Objective:To evaluate the feasibility of pelvic floor muscle reconstruction for women with vaginal laxity accompanied by stress urinary incontinence (SUI).Methods:A prospective cohort clinical study was conducted to collect clinical data from patients with vaginal laxity and SUI admitted to the Urogenital Reconstructive and Gender-affirming Department at the Plastic Surgery Hospital, Chinese Academy of Medical Sciences, and the Department of Urology, Third Medical Center, Chinese PLA General Hospital, from January 2019 to September 2022. Patients underwent surgical treatment for pelvic floor muscle reconstruction. The cough provocation test and the patient global impression of improvement (PGI-I) scale were utilized as objective and subjective indicators of treatment effecacy, respectively. The urinary incontinence quality of life scale (I-QOL) and the pelvic organ prolapse and urinary incontinence sexual function questionnaire 12(PISQ-12) were used to evaluate the changes in quality of life and sexual funtion. The changes in pelvic floor anatomical structure were evaluated by pelvic floor ultrasound. Data analysis was performed using SPSS version 23.0. The I-QOL and PISQ-12 scores, posterior vesicourethral angle, urethral rotation angle, and bladder neck motion before and after surgery were analyzed using paired t-test, with P<0.05 was considered statistically significant. Results:A total of 36 female patients were included, with an average age of 41.7 years (ranged 24-51 years) and an average body mass index of 23.8 kg/m 2. The average operation time was 76.2 minutes, and the average blood loss was 84.5 milliliters. After 12-27 months of postoperative follow-up, the objective and subjective cure rates were 86.1% (31/36) and 88.9% (32/36), respectively. The sexual function and quality of life of the patients were significantly improved compared with the preoperative results, and postoperative pelvic floor ultrasound results showed significant improvement. The I-QOL and PISQ-12 scores 12 months after surgery were statistically significant compared with those before surgery ( P<0.01). Postoperative pelvic floor ultrasonography revealed statistically significant differences in posterior vesicourethral angle, urethral rotation angle, and bladder neck motion during maximum Valsalva maneuver compared to preoperative data ( P<0.01). Conclusion:Pelvic floor muscle reconstruction is a safe and effective surgical method for patients with vaginal laxity combined with SUI. This procedure can significantly improve sexual quality of life and alleviates SUI symptoms, restores anatomical structure in the female pelvic floor, and enhances overall quality of life.

Objective:To explore the clinical and genetic characteristics of four children with Kabuki syndrome (KS) due to variants of KMT2D gene. Methods:Four children with KS diagnosed at the Children′s Hospital of Shanxi Province between January 2020 and December 2022 were selected as the study subjects. Whole exome sequencing was carried out for the children and their family members. Candidate variants were verified by Sanger sequencing and pathogenicity analysis.Results:The KS phenotype scores for the four children were 7, 8, 6, and 6, respectively. Child 2 also presented with a rare solitary kidney malformation. Genetic testing revealed that all children had harbored novel de novo variants of the KMT2D gene, including c. 16472_16473del, c. 858dup, c. 11899C>T, and c. 12844C>T, respectively. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), all of the variants were classified as pathogenic. Conclusion:For children showing phenotypes such as distinctive facial features, intellectual disability, developmental delay, cardiac abnormalities, and urinary system anomalies, KS should be considered. Early diagnosis and intervention can be achieved through genetic testing, especially in the presence of KMT2D gene mutations.

Objective:To investigate the applicable effect of anatomical retroperitoneoscopic adrenalectomy in treating patients with adrenal tumors.Methods:A total of 112 patients with adrenal tumors admitted to the Department of urology of The Third Medical Center of Chinese PLA General Hospital from January 2016 to January 2021 were selected as research subjects，and they were divided into control group and study group according to the double-blind method，with 56 cases in each group. The patients in the control group were treated with laparoscopic transabdominal adrenalectomy，while the patients in the study group were treated with anatomical retroperitoneoscopic adrenalectomy. The clinical indicators of the two surgical methods were compared. Before and six hours after surgery，the serum levels of inflammatory factors including interleukin-6（IL-6），interleukin-1β（IL-1β），and hypersensitive C-reactive protein（hs-CRP）were detected by enzyme-linked immunosorbent assay（ELISA），and the electrolytes such as Na +，K +，and bicarbonate（HCO 3-）were detected by the America-made Medica electrolyte analyzer. The prognosis and incidence of complications in the two groups were observed. Results:Compared with the control group，the time spent in operation，the time spent for drainage tube placement and gastrointestinal function recovery，and hospital stay were all shorter in the study group（ P < 0.05 or P < 0.01）. After surgery，the serum levels of IL-6，IL-1β，and hs-CRP in the study group were significantly lower than those in the control group，and the levels of Na + and HCO 3- in the study group were also lower than those in the control group，while the K + level was higher than that in the control group，all with statistically significant differences（ P < 0.05 or P < 0.01）. The incidence of complications in the study group［3.57%（2/56）］was significantly lower than that in the control group［（14.29%（8/56）］，with statistically significant difference（ P < 0.05）. No recurrence or metastasis occurred in the two groups during the six-month follow-up after surgery. Conclusion:Anatomical retroperitoneoscopic adrenalectomy can better reduce the surgery trauma to patients with adrenal tumors，lessen the impact on the internal environment of patients，effectively promote the postoperative rehabilitation process，and has higher safety.

ObjectiveTo investigate the clinical effect of endoscopic dense ligation in the treatment of esophageal variceal bleeding. MethodsA total of 156 patients who underwent endoscopic ligation for the first time due to esophageal variceal bleeding caused by cirrhotic portal hypertension in Shijiazhuang Fifth Hospital from July 2015 to June 2016 were enrolled, and according to the treatment method, they were divided into dense ligation group with 76 patients and non-dense ligation group with 80 patients. The patients were followed up for 1-2 years, and a statistical analysis was performed for the eradication or disappearance rate of varices, the number of times of ligation, early rebleeding rate, late-onset rebleeding rate, and the incidence rate of adverse reactions. The t-test was used for comparison of continuous data between two groups, and the chi-square test or Fisher′s exact test was used for comparison of categorical data between two groups. ResultsThere were significant differences between the dense ligation group and the non-dense ligation group in the eradication or disappearance rate of varices (71.05% vs 55.00%, χ2=4.300, P=0.038) and number of times of ligation (χ2=8.511, P=0.014), and there were no significant differences between the two groups in early rebleeding rate (5.26% vs 2.50%, P＞0.05), late-onset rebleeding rate (7.89% vs 10.00%, P＞0.05), recurrence rate of varices (13.16% vs 18.75%, P＞0.05), and incidence rate of adverse reactions (26.32% vs 21.25%, P＞0.05). There was a significant difference in the time to recurrence of varices between the two groups (11.90±1.89 months vs 7.07±1.17 months, t=2.295, P=0.031). Of all 156 patients, 2 (1.28%) died during follow-up, with 1 patient in the dense ligation group and 1 in the non-dense ligation group. There was no significant difference in mortality rate between the two groups (P＞0.05). ConclusionEndoscopic dense ligation is a safe technique for the treatment of esophageal variceal bleeding and is better than non-dense ligation in terms of the disappearance rate of varices and number of times of ligation. Endoscopic dense ligation also allows a longer time to recurrence of varices than non-dense ligation.
