Objective: To investigate the efficacy of implantable neuromuscular electrical stimulation system on stress urinary incontinence (SUI) model in female rats. Methods: A total of 21 female infertile SD rats were randomly divided into the control，sham stimulation，and stimulation groups，with 7 rats in each group.All rats received vaginal dilation (VD) to simulate postpartum SUI.One week after VD，the control group was given normal feeding，stimulators were implanted in the pelvic floor muscles of the sham stimulation and stimulation groups.The sham stimulation group received normal feeding for 2 weeks，and the stimulation group received pelvic floor electrical stimulation (PFES) for 2 consecutive weeks.The leak point pressure (LPP) of each rat was measured with cystometry before VD (baseline value)，1 week after VD，and 2 weeks after PFES. Results: In the control group and sham stimulation group，LPP increased after 2 weeks of treatment compared with that after 1 week of VD，but it still did not return to the baseline level (P<0.001).In the stimulation group，after 2 consecutive weeks of PFES，LPP increased significantly compared with that 1 week after VD，and returned to the baseline value (P>0.05).There was no significant difference in the LPP baseline values and levels after 1 week of VD among the 3 groups (P>0.05).The LPP in the stimulation group after 2 weeks of PFES was significantly higher than that in the sham stimulation group and stimulation group (P<0.001). Conclusion: The implantable neuromuscular electrical stimulation system is effective in short-term intervention of SUI in female rats，the further studies are needed to confirm the long-term efficacy and safety of the system，the optimal stimulation sites，optimal stimulation parameters，and potential mechanisms of action.

Purpose: Gold-standard urodynamic examination is widely used in the diagnosis and treatment of lower urinary tract dysfunction. The purpose of urodynamic quality control is to standardize urodynamic examination and ensure its clinical reference value. In our study, we attempted to use a deep learning (DL) algorithm model, mainly for the recognition of typical urodynamic signal, to help physicians complete high-quality urodynamic examinations. Methods: Urodynamic image data from 2 cohorts of adult patients with neurogenic bladder were used: (1) 300 patients with neurogenic bladder in our center from 2012 to 2018 (1,960 images used to train and validate the DL model); and (2) 100 patients with neurogenic bladder from 2020 to 2021 (695 images used to test the performance of the DL model). This resulted in a total of 2,655 images to train, validate and test the DL algorithm to predict the urdynamic signals. Results: Yolov5l had the best detection performance and the highest comprehensive index score (F1, 0.81; mean average precision, 0.83). Our study is a retrospective single-center study, and the generalization ability of the model has not been verified. Conclusions DL algorithms can help operators identify typical urodynamic signals in real time, improve the interpretation and quality of urodynamic examination, and benefit patients.

Objective To investigate the long-term efficacy and postoperative complications of artificial urinary sphincter (AUS) implantation in patients with stress urinary incontinence caused by traumatic urethral injury, so as to provide reference for the treatment of this condition. Methods A retrospective study was conducted on the clinical data of 26 patients treated at our center during Apr.2002 and Dec.2024. All patients had severe persistent urinary incontinence due to traumatic urethral injury and underwent AUS implantation. The daily pad usage and visual analog scale (VAS) scores before surgery and 6 months to 1 year after surgery were compared to evaluate the efficacy. Complications were recorded and analyzed, and the survival was analyzed using the Kaplan-Meier method. Results The patients included 25 males and 1 female, with a mean age (41.8± 16.0) years, median disease duration of 10.0 (2.0,16.0) years and follow-up of (11.7±5.9) years. One month postoperatively, all patients successfully activated the AUS device. At the latest follow-up (Jun.2025),20 devices (including 3 revised) were functioning. The social continence rate was 61.5% (16/26), and complete continence rate 38.5% (10/26). Daily pad usage decreased significantly from a preoperative median of 3.5 (3.0,5.0) pads/day to 0.5 (0,1.0) pads/day (P<0.05). The median VAS score decreased from 8.0 (7.0,8.0) to 1.0 (0,1.0) (P<0.05). Complications occurred in 34.6% (9/26) patients, including urethral erosion (4 cases), fluid leakage (3 cases) and infection (2 cases). There was a significantly difference in age between patients with complications and those without complications [ (33.1±12.3) years vs. (46.4±16.1) years, P<0.05]. The median survival was 16 years, with the 5-year,10-year, and 15-year survival probabilities of 75.8%, 75.8% and 58.3%. Conclusion AUS implantation demonstrates good long-term efficacy and durability, and is a recommended treatment option.

Objective To investigate the international occupational classification of rehabilitation-therapy professionals,and analyze the core competencies,to improve the occupational system of rehabilitation-therapy professionals in China. Methods According to Standard Country or Area Codes for Statistical Use that prepared by the Statistics Division of the United Nations and Human Development Index of each country or area,the occupational classification of rehabil-itation-therapy professionals in the International Labour Organization(ILO)and 17 typical countries or areas was compared,and rehabilitation competency framework(RCF)was used to analyze the core competencies. Results The occupational classification or similar documents of ILO and 15 countries or areas were obtained.Except China categorizing rehabilitation-therapy professionals as technicians,all the documents set detailed occupations of rehabilitation-therapy professionals such as physical therapist and speech therapist as formal full-time occupa-tion;and ILO and 14 countries or areas defined these detailed occupations as professional occupation.The core competencies of technicians only involved a very small number of competencies and activities in RCF,while the core competencies of detailed occupations of rehabilitation-therapy professionals covered the vast majority of competencies and activities in RCF.There were differences in RCF competencies and activities involved in the core competencies of detailed occupations of rehabilitation-therapy professionals. Conclusion The core competencies are different between rehabilitation-therapy professionals and technicians,and among different detailed occupations of rehabilitation-therapy professionals.It is important for China to establish the detailed occupations of rehabilitation-therapy professionals as formal full-time occupation.The education re-lated to therapy and rehabilitation in China is gradually aligning with international standards,legislation on occu-pational qualification admission for rehabilitation-therapy professionals should be carried out,and make the reha-bilitation-therapy professionals to be professional occupation.

Objective:To understand the use of post-exposure prophylaxis (PEP) and analyze related factors among men who have sex with men (MSM) in Qingdao, and provide a reference for the AIDS prevention and control in this population.Methods:A cross-sectional survey conducted from April 2022 to February 2023. Relying on MSM social groups in Qingdao, a snowball sampling method was applied to recruit research subjects who met the inclusion criteria of age ≥18 years old, having had homosexual anal or oral sex in the past six months, and HIV-negative or infection status unknown. The sample size was estimated at 566. Data on demographic characteristics, sexual behavior characteristics, PEP use, and others of the research subjects was collected through on-site questionnaires. The logistic regression model was used to analyze the factors associated with using PEP.Results:A total of 811 participants were recruited, mainly aged 25-34 (53.6%, 435/811), unmarried (74.7%, 606/811), with an average monthly income of ≥5 000 yuan (52.2%, 423/811), and having lived in Qingdao for ≥10 years (75.6%, 613/811). The proportion of those who knew the HIV status of their sexual partners in the last six months was 67.1% (544/811), and those with HIV-positive partners were 3.6% (29/811). In the last six months, the proportion of participants who had group sex (86.4%, 701/811), unprotected anal sex (98.2%, 796/811), and use of club drugs (80.3%, 651/811) was high. Moreover, 28.4% (230/811) had used PEP. The multivariate logistic regression analysis showed that the factors related to the use of PEP included divorced or widowed (a OR=5.46,95% CI:1.96-15.17), average monthly income ≥5 000 yuan (a OR=2.04,95% CI:1.44-2.89), same-sex sexual orientation (a OR=0.40,95% CI:0.22-0.71), having HIV-positive sexual partners in the last six months (a OR=2.54,95% CI:1.13-5.71) and having been tested for HIV ≥3 times in the last six months (a OR=1.46,95% CI:1.04-2.06). Conclusions:The prevalence of risk behaviors among MSM in Qingdao was high, and the use of PEP was low. In the future, it is essential to increase HIV/AIDS prevention education among MSM, promote MSM to know the HIV status of their sexual partners, and reduce the prevalence of risk behaviors among this population. Additionally, explore medical insurance reimbursement plans for PEP to reduce utilization costs and promote the use of PEP by MSM after HIV exposure occurs as soon as possible.

The 39th annual meeting of the European Association of Urology was successfully held in Paris, France from April 5 to April 8, 2024. This meeting deeply discussed many clinical hotspots and controversial topics in the field of urinary control. This article mainly introduces the diagnosis, treatment and related clinical translation research of lower urinary tract symptoms (LUTS), overactive bladder (OAB), neurourology, and urinary incontinence that were focused on at the conference.

Sacral neuromodulation, tibial neuromodulation, and intravesical electrical bladder stimulation are the neuromodulation techniques widely used in the clinical practice of lower urinary tract dysfunction in China, and they are constantly innovated and developed, and various new devices and methods from China are innovated.

This article focuses on the current status and progress of the above two aspects of national and international research, emphasizes the need to adhere to uphold fundamental principles and break new ground in the research and practice of neuromodulation of lower urinary tract dysfunction, and elaborates on the prospect of the research on the central mechanism of neuromodulation as well as the challenges that exist.

Objective:To explore the cerebral cortical mechanism of intravesical electrical stimulation (IVES) on neurogenic underactive bladder (UAB).Methods:A prospective study was conducted on healthy subjects (HS) recruited in our center and patients with neurogenic UAB treated with IVES from March 2022 to June 2023 were included. HS inclusion criteria: females aged 18-60 years; the 72-hour voiding diary was normal; the urine volume was 200-400 ml, and the free urine flow rate > 20 ml/s. HS exclusion criteria: urinary and neurological related disorders; major diseases of all systems of the body; cognitive dysfunction. Inclusion criteria for UAB patients: females aged 18-60 years; neurogenic UAB due to incomplete spinal cord injury (grade D or E) with a duration of > 3 months; previous routine use of intermittent catheterization, or indication of intermittent catheterization (residual urine accounts for > 40% of functional bladder capacity). Exclusion criteria for UAB patients: decreased bladder compliance on urodynamic examination; symptomatic urinary tract infection; concomitant hydronephrosis, vesicoureteral reflux or renal insufficiency (serum creatinine greater than 1.5 times of the normal upper limit); bladder tumors; neurological related diseases; pregnant or trying to conceive; a pacemaker or defibrillator has been implanted in the body. At baseline, the 24-hour voiding diary, residual urine, voiding efficiency, first sensation of bladder filling volume and American Urological Association Symptom Index Quality of Life scores(AUA-SI-QOL)were recorded, and the resting state-functional near-infrared spectroscopy scans of the prefrontal cortex was completed in the bladder emptying state and the strong desire to void stage. The UAB group was re-evaluated after completing 20 IVES treatments. Improvement in residual urine > 50% was defined as success of IVES treatment. The differences in functional connectivity in the prefrontal lobe between the successful UAB group before and after IVES and between the successful UAB group and the HS group were compared.Results:A total of 16 HS and 18 UAB patients were included. Eleven UAB patients were successfully treated by IVES, and 7 UAB patients were failed. Compared with pre-treatment, the post-treatment residual urine volume [90.0(50.0, 120.0) ml vs. 210.0(110.0, 300.0) ml], 24-h intermittent catheterization [3.0(2.0, 4.0) times vs. 4.0(3.0, 4.0) times], first sensation of bladder filling volume [275.0(245.0, 280.0) ml vs. 295.0 (290.0, 315.0) ml] and AUA-SI-QOL score [2.0 (2.0, 3.0) vs. 4.0 (4.0, 4.0)] of the successful UAB group were significantly lower ( P<0.05), and the voiding efficiency [75.0% (69.0%, 85.0%) vs. 42.0% (35.0%, 77.0%)] was significantly higher ( P< 0.05). Before IVES, the successful UAB group compared with the HS group, internal prefrontal functional connectivity was significantly attenuated in the bladder emptying state involving 5 brain regions: bilateral dorsolateral prefrontal cortex (DLPFC), bilateral frontopolar area, and left pars triangularis. And in the strong desire to void stage significantly attenuated involving 4 brain regions: bilateral DLPFC and bilateral frontopolar area. In the successful UAB group after IVES compared with the HS group, internal prefrontal functional connectivity was significantly attenuated in the bladder emptying state involving 2 brain regions: left pars triangularis and left DLPFC. And in the strong desire to void stage involving 4 brain regions: left DLPFC, right frontopolar area, the left pars opercularis Broca's area, and the left pars triangularis. After IVES in the successful UAB group compared with pretreatment, prefrontal internal functional connectivity was significantly enhanced in the bladder emptying state involving 4 brain regions: bilateral DLPFC and bilateral frontopolar area, and in the strong desire to void stage involving 4 brain regions: bilateral DLPFC, bilateral frontopolar area. Conclusions:Significant enhancement of functional connectivity within the prefrontal lobes (bilateral DLPFC and bilateral frontopolar area) may be the cortical mechanism of IVES for neurogenic UAB.
