OBJECTIVE: To explore the application progress and clinical value of digital technologies in the surgical treatment of ankylosing spondylitis (AS). METHODS: By systematically reviewing domestic and international literature, the study summarized the specific application scenarios, operational procedures, and technical advantages of digital technologies [including preoperative three-dimensional (3D) planning, intraoperative real-time navigation, robot-assisted surgery, and 3D printing] in AS surgery, and analyzed their impact on surgical accuracy, complication rates, and clinical outcomes. RESULTS: Digital technologies significantly improve the precision and safety of AS surgery. Preoperative 3D planning enables personalized surgical protocols; intraoperative navigation systems dynamically adjusts surgical trajectories, reducing the risk of iatrogenic injury; robot-assisted surgery can minimize human errors and enhance implant positioning accuracy; 3D-printed anatomical models and guides optimize the correction of complex spinal deformities. Furthermore, the combined applications of these technologies shorten operative time, reduce intraoperative blood loss, decrease postoperative complications (e.g., infection, nerve injury), and accelerate functional recovery. CONCLUSION Through multidimensional integration and innovation, digital technologies provide a precise and minimally invasive solution for AS surgical treatment. Future research should focus on their synergy with biomaterials and intelligent algorithms to further refine surgical strategies and improve long-term prognosis.

OBJECTIVE: To summarize the research progress on knee laxity of biomechanics and prevention and treatment after posterior cruciate ligament (PCL) reconstruction. METHODS: The domestic and international literature on the prevention and treatment of knee laxity after PCL reconstruction in recent years was extensively reviewed and analyzed. RESULTS: Different degrees of knee laxity often occur after PCL reconstruction, which can lead to poor prognosis in patients. The causes are associated with a variety of factors, including abnormal graft remodeling (such as differences in healing time and biomechanics among different types of grafts), tunnel position deviation (such as graft wear caused by the "killer turn" effect), and mechanical factors in postoperative rehabilitation (such as improper early weight-bearing and range of motion). These factors may promote graft elongation, increase early posterior tibial translation, and thereby induce knee laxity. CONCLUSION While PCL reconstruction improves knee stability, it is crucial to focus on and prevent postoperative knee laxity. However, current surgical methods are limited by factors such as graft characteristics, surgical technique flaws, and rehabilitation protocols, and thus can not fully correct the issue of abnormal postoperative laxity. Surgical techniques and treatment strategies still need further improvement and optimization to enhance patients' postoperative outcomes and quality of life.

OBJECTIVE: To optimize the perioperative management experiences for breast cancer patients undergoing direct-to-implant-based breast reconstruction, and provide reference for clinical practice. METHODS: A comprehensive review of recent domestic and international literature was conducted to systematically summarize the key points of perioperative management for direct-to-implant-based breast reconstruction, including preoperative health education, intraoperative strategies, and postoperative management measures, along with an introduction to the clinical experiences of West China Hospital of Sichuan University. RESULTS: Standardized perioperative management can effectively reduce the incidence of complications and achieve excellent cosmetic outcomes and quality of life after operation. Preoperative management includes proactive health education to alleviate patients' anxiety and improve treatment compliance, as well as comprehensive assessment by surgeons of the patient's physical condition and reconstructive expectations to select the most appropriate implant. Intraoperative management consists of strict aseptic technique, minimizing implant exposure, preserving blood supply to the nipple-areola complex (e.g., by using minimally invasive techniques or indocyanine green angiography, etc), and meticulous hemostasis. Postoperative management encompasses multimodal analgesia, individualized drain management (such as early removal or retaining a small amount of fluid to optimize contour), infection prevention and control (including topical and systemic antibiotics, ultrasound-guided minimally invasive drainage), guidance on rehabilitation exercises (early activity restriction followed by gradual recovery), and regular follow-up to evaluate aesthetic results and monitor for complications. CONCLUSION Establishing a standardized, multidisciplinary perioperative management framework markedly enhances surgical safety and patient satisfaction, thereby providing a replicable benchmark for direct-to-implant-based breast reconstruction across diverse clinical settings.

PURPOSE: Over 30,000 hip hemiarthroplasties for neck of femur fractures are performed annually in the United Kingdom (UK). The national recommendation is via the lateral approach, to reduce the risk of dislocation, with the potential expense of reduced function and mobility post-operatively. Muscle-sparing approaches, such as SPAIRE (sparing piriformis and internus repairing externus), have been invented to address the issue of dislocation. METHODS: We performed a retrospective data collection at a single center with a high annual volume of hip hemiarthroplasties over 12 months. All patients who had hip hemiarthroplasty as their primary treatment were included. Patients who passed away and were non-ambulant before their surgery were excluded from the study. Our primary outcome was the dislocation rate and secondary outcomes were the time to mobilization after surgery and the duration of surgery. Statistical analysis was performed using XLSTAT software. RESULTS: We identified 194 cases, and these were divided into 3 groups based on the surgical approach: SPAIRE (n = 43), lateral (n = 97), and posterior (n = 54). Groups had similar demographics and a minimum 3-month follow-up after surgery. There were no dislocations in the SPAIRE group, whereas the dislocation rate for the other 2 groups was 2.5% in the lateral and 9.1% in the posterior groups at 6 months post-surgery. There was an earlier return to mobility in the SPAIRE (1.4 day) compared to the 2 other groups ( 2 days and 2.6 days). Average surgical times were very similar among all 3 groups (74 min vs. 79 min vs. 71 min). CONCLUSION The SPAIRE approach seems to be safe and provides a low risk of dislocation and good post-operative function for patients undergoing hip hemiarthroplasties.

Urinary incontinence is a common complication following robot-assisted radical prostatectomy (RARP). Urethral length has been identified as a factor affecting postoperative continence recovery. In this meta-analysis, we examined the association between use of the maximal urethral length preservation (MULP) technique and postoperative urinary continence in patients undergoing RARP. We conducted a comprehensive search of PubMed, Web of Science, Embase, and the Cochrane Library up to December 31, 2023. The quality of the literature was assessed using the Newcastle-Ottawa Scale. A random-effects meta-analysis was performed to synthesize data and calculate the odds ratio (OR) from eligible studies on continence and MULP. Six studies involving 1869 patients met the eligibility criteria. MULP was positively associated with both early continence (1 month after RARP; Z = 3.62, P = 0.003, OR = 3.10, 95% confidence interval [CI]: 1.68-5.73) and late continence (12 months after RARP; Z = 2.34, P = 0.019, OR = 2.10, 95% CI: 1.13-3.90). Oncological outcomes indicated that MULP did not increase the overall positive surgical margin rate or the positive surgical margin status at the prostate apex (both P > 0.05). In conclusion, the use of the MULP technique in RARP significantly improved both early and late postoperative continence outcomes without compromising oncological outcomes.

Transcatheter aortic valve replacement (TAVR) has emerged as the first-line treatment for aortic valve stenosis. Coronary obstruction is a severe complication of TAVR, with mortality rates exceeding 30%. Coronary obstruction can be classified as acute or delayed based on the timing of the onset, and as direct or indirect obstruction according to the underlying mechanism. Risk factors for predicting coronary obstruction include a small sinus of Valsalva diameter, excessively long native leaflets, low coronary height, and small sinotubular junction height and diameter. Accurate preoperative assessment of these anatomical parameters using CT is crucial for selecting the appropriate valve type, size, and implantation depth. Preventive technical strategies for coronary obstruction include intraoperative interventional treatments (such as the "Chimney" stenting technique), leaflet modification (such as the BASILICA technique), and alignment of the annulus and coronaries. These techniques have demonstrated significant efficacy in reducing the incidence of coronary obstruction and associated mortality. This paper reviews the epidemiology, classification, and mechanisms of coronary obstruction, with a particular focus on the identification, prevention, and treatment of high-risk patients. The aim is to highlight the importance of recognizing and managing coronary risks during TAVR and to provide actionable recommendations for the prevention and treatment of coronary obstruction in clinical practice.

OBJECTIVE: To investigate the effect of inverted-Y urethral function-preserving holmium laser enucleation of the prostate (HoLEP) on stress urinary incontinence after surgery in patients with BPH. METHODS: We retrospectively analyzed the clinical data on 109 cases of BPH treated in our hospital from June 2022 to May 2023 by traditional HoLEP with preservation of the apical prostatic urethral valve (group A, n = 52) or inverted-Y urethral function-preserving HoLEP (group B, n = 57). We recorded the intra- and post-operative parameters, evaluated the urinary incontinence status and post-void symptoms according to the International Continence Society standards, and analyzed the effect of inverted-Y versus traditional HoLEP in improving the postoperative urinary incontinence of the patients. RESULTS: The incidence rate of stress urinary incontinence after catheter removal was significantly lower in group B than in A (10.52% vs 26.92%, P = 0.027), and so was it at 2 weeks after surgery (1.75% vs 11.54%, P = 0.037), and at 1 month postoperatively (0% vs 7.69%, P = 0.033). CONCLUSION For the treatment of BPH, inverted-Y urethral function-preserving HoLEP is superior to traditional HoLEP with preservation of the apical prostatic urethral valve in improving stress urinary incontinence after surgery.

OBJECTIVE: To explore the effect of evidence-based standardized procedures (SOP) on urinary incontinence management in patients with radical prostatectomy. METHODS: Sixty-three patients who underwent radical prostatectomy from October 2022 to September 2023 were included in the control group. And 63 patients who underwent radical prostatectomy from October 2023 to September 2024 were included in the observation group. The patients in the control group received routine perioperative care. As an addition, the SOP on urinary incontinence management was performed in the patients of observation group. The incidence of urinary incontinence, severity of urinary incontinence (1h urine pad test), quality of life (Incontinence Quality of Life Questionnaire) and comfort level (General Comfort Question) of the two groups were compared after 3 and 6 months of surgery. RESULTS: The incidence of urinary incontinence at 3 and 6 months after operation in the observation group was 36.51% and 19.05%, respectively, which were lower than those (53.97% and 38.10%) of the control group, respectively. And the incidence rates of the two groups decreased significantly (P<0.05).The score of life quality after 3 months of operation was (56.17±12.75) in the control group, which was lower than that (70.41±14.50) of the observation group. The 3-month postoperative comfort score was (52.73±11.26) in the control group and (63.49±13.52) in the observation group. The 6-month postoperative incontinence quality of life score was (64.70±11.38) in the control group and (85.41±12.04) in the observation group. And the 6-month postoperative comfort score was (60.96±8.04) in the control group and (83.49±12.04) in the observation group. The quality of life and comfort scores of the two groups 6 months after operation were significantly improved than those 3 months after operation, and the improvement of the observation group was more obvious than that of the control group (P<0.05). There were significant differences in the degree of urinary incontinence between the two groups at 3 months and 6 months after operation (P<0.05). CONCLUSION SOP management for the patients underwent radical prostatectomy can be an effective method for reducing the incidence of postoperative urinary incontinence, which promotes the recovery of postoperative urinary control.

OBJECTIVE: This study aims to analyze the influence factors of lower urinary tract symptoms (LUTS) in patients receiving radical prostatectomy for prostate cancer, and to explore effective nursing strategy in order to provide a theoretical basis for improving the postoperative quality of life of patients. METHODS: A retrospective study was conducted on 103 elderly male patients who underwent radical prostatectomy for prostate cancer in the Department of Urology at General Hospital of Eastern Theater Command from August 2022 to August 2024. The patients were categorized into two groups based on whether LUTS occurred. Demographic and clinical characteristics, perioperative parameters, follow-up data, and participation in pelvic floor muscle training were analyzed to identify risk factors associated with postoperative LUTS. RESULTS: The incidence of postoperative LUTS in the patients with LUTS before the operation was significantly higher than that in the patients without LUTS before the operation (68.42% vs 32.61%, P=0.001). Additionally, the use of larger catheters (22F) was closely associated with an increased incidence of postoperative LUTS(P<0.01). Pelvic floor exercises demonstrated a significant protective effect, with patients who engaged in pelvic floor exercises exhibiting a lower incidence of postoperative LUTS (38.60% vs 60.87%, P=0.040). Regression analysis further revealed that pelvic floor exercises was the protective factor for postoperative LUTS (OR=0.215, 95%CI: 0.091－0.508, P<0.01). CONCLUSION Preoperative LUTS and catheter size are significant risk factors for the occurrence of postoperative LUTS following radical prostatectomy. Pelvic floor muscle exercise after surgery has a protective effect. Postoperative personalized nursing interventions are necessary for different patients to achieve optimal recovery outcomes.
