Objective: To evaluate the long-term efficacy and safety of low-intensity extracorporeal shock wave therapy (Li-ESWT) for refractory prostate-pelvic syndrome (PPS). Methods: Clinical data of 173 patients with refractory PPS undergoing Li-ESWT at our hospital during Jan.2020 and Jan.2023 were retrospectively analyzed.All patients received weekly treatment for 8 consecutive weeks.Changes in the National Institutes of Health chronic prostatitis symptom index (NIH-CPSI)，international prostate symptom score (IPSS)，visual analog scale (VAS)，and international index of erectile function-5 (IIEF-5) were compared before treatment，immediately，1，3，and 6 months after treatment. Results: A total of 142 patients (82.1%) completed all follow-ups.Compared to baseline data，there was a statistically significant improvement in NIH-CPSI，IPSS，VAS，and IIEF-5 scores immediately after treatment and 1，3，and 6 months after treatment (P<0.01).No significant adverse reactions or complications were observed throughout the follow-up.At the time of treatment completion，115 patients (81.0%) had a decrease of ≥6 in NIH-CPSI; 99 patients (69.7%) had a decrease of ≥3 in IPSS; 121 patients (85.2%) had a decrease of ≥3 in VAS; 105 patients (73.9%) had an increase of ≥4 in IIEF-5.At the 6-month follow-up，patients who responded to treatment maintained satisfactory therapeutic effects. Conclusion: Li-ESWT can significantly improve clinical symptoms and quality of life for patients with refractory PPS，with therapeutic effects lasting at least 6 months.

Objective: To explore the association between preoperative aspartate transaminase to alanine transaminase (AST/ALT) ratio and the outcomes of urothelial cancers. Methods: After a systematic search of Web of Science，PubMed and Embase before Aug.2024，14 studies were included in the Meta-analysis.The hazard ratios (HRs) with 95% confidence interval (CI) for overall survival (OS)，cancer-specific survival (CSS)，and recurrence-free survival (RFS) were analyzed using STATA 15.0 software. Results: The Meta-analysis included a total of 8190 patients.Urothelial cancer patients with an elevated preoperative AST/ALT ratio had worse OS (HR=1.92，95% CI：1.38-2.67，P<0.001)，CSS (HR=2.12，95% CI：1.48-3.05，P<0.001)，and RFS (HR=1.63，95% CI：1.27-2.10，P<0.001).In subgroup analyses，preoperative AST/ALT ratio had a better predictive value for OS，CSS，and RFS in patients with bladder cancer than in patients with upper tract urothelial carcinoma，and a better predictive value in Asian population than in Caucasian population (P<0.001). Conclusion: A high preoperative AST/ALT ratio is associated with poor OS，CSS and RFS in urothelial cancers，particularly among the Asian population.

[Objective] To Compare the effectiveness of conventional local anesthesia (CLA) and two-plane local anesthesia (TPLA) in percutaneous nephrolithotomy (PCNL) so as to provide reference for clinical selection of appropriate anesthetic methods. [Methods] Clinical data of 345 patients with renal or ureteral calculi who underwent PCNL under local infiltration anesthesia in our hospital during Jan.2013 and Dec.2023 were retrospectively analyzed.The patients were divided into CLA group (n=114) and TPLA group (n=231) according to anesthetic methods.The intraoperative visual analogue scale (VAS) score, stone-free rate and incidence of complications were compared between the two groups. [Results] There were no significant differences in the baseline data between the two groups (P>0.05). When the cutaneous and renal channels were established, the VAS score was lower in the TPLA group than in the CLA group [(3.2±0.5) vs. (3.8±0.4), P=0.023]. However, there was no significant difference in the VAS score during lithotripsy [(3.3±0.5) vs. (3.4±0.5), P=0.061]. There were no significant differences between the two groups in terms of operation time, stone-free rate, hemoglobin drop, postoperative hospital stay, and time to remove nephrostomy tube and DJ tube retention time (P>0.05). [Conclusion] Both CLA and TPLA can provide good analgesia in PCNL, but TPLA can significantly reduce the pain sensation when the cutaneous and renal channels are established.

Objective To investigate the changing trends in etiology and treatment of male urethral stricture in recent 10 years.Methods A total of 940 male patients with urethral stricture admitted to the Department of Urology of Beijing Jishuitan Hospital during Jan.2013 and Dec.2022 were continually collected.The clinical data were divided into two groups according to the time of admission,namely the group from 2013 to 2017 and the group from 2018 to 2022,for a comparative analysis of the previous and subsequent 5 years.The etiology,location,length and the type of treatment of urethral stricture were retrospectively analyzed.Results The causes of the 940 cases of male urethral stricture were trauma in 447(47.55％),iatrogenic injury in 220(23.40％),idiopathic causes in 128(13.62％),lichen sclerosus(LS)in 78(8.30％),infection in 46(4.89％),and other causes in 21(2.23％).The treatment methods were urethroplasty in 691(73.51％),direct vision internal urethrotomy(DVIU)in 122(12.98％),urethral dilatation in 86(9.15％),and suprapubic cystostomy in 41(4.36％).Compared with the previous 5 years,in the past 5 years,the proportion of urethral stricture caused by trauma decreased significantly(60.34％vs.41.71％,P＜0.001),while the proportion of iatrogenic injury increased significantly(17.63％vs.26.05％,P=0.005).In the past 5 years,the proportion of urethroplasty increased from 68.81％to 75.66％(P=0.027),while the proportion of DVIU decreased from 19.66％to 9.92％(P＜0.001).Inthe past 5 years,the proportion of membranous urethral stenosis decreased significantly(26.98％vs.50.85％,x2=51.06,P＜0.001),the proportion of penile urethral stricture(21.40％vs.7.80％,=26.37,P＜0.001)and meatal stenosis(9.30％vs.4.75％,x2=5.80,P＜0.001)increased significantly.Conclusion In the past decade,trauma was the main cause of male urethral strictures,but its proportion showed a decreasing trend.Iatrogenic injury led to a gradual increase in urethral strictures,which was the second leading cause of male urethral stricture.The application of urethroplasty increased significantly,making it the main treatment method for male urethral stricture.

Objective:The preliminary results was reported regarding the treatment of mesenteric torsion by mesenteric fixation in the last decade, especially preventing recurrence of mesenteric torsion by mesenteric fan-shaped fixation.Methods:We selected 12 patients who received emergency operation in Chongqing Hospital of the First Affiliated Hospital of Guangzhou University of Chinese Medicine from December 2010 to March 2022. All of them were made a definite diagnose of mesenteric torsion by the preoperative CT scan or exploratory laparotomy. The recurrence of mesenteric torsion will be prevented by taking the operation of mesenteric fan-shaped fixation. This technique is suitable for the patient who is suffering total mesenteric torsion, but enteric necrosis is excluded affirmatively. The operation is consists of the following progress: (1) Exploratory laparotomy to check for necrosis of the bowel and for lesions other than torsion. (2) Mesenteric torsion derotation.(3) Mesenteric linear fixation; the right posterior lower border of the small mesentery (terminal ileal mesentery) is intermittently sutured to the posterior peritoneum of the right lower quadrant to increase the width of the base of the small mesentery. (4) Mesenteric fan-shaped fixation, which is fan-shaped to the lower left and fixed in the posterior peritoneum, shortening the length of the mesentery and further increasing the width of the mesentery and posterior peritoneal fixation.Results:A total of 12 patients with mesenteric torsion were treated by operation for 15 times in all. Among them, 3 cases received resection of most small bowel were performed without recurrence; 3 patients received only derotation for a total of 4 times, 2 cases recurred, 1 of them recurred twice; 4 cases underwent derotation and mesenteric linear fixation,and 1 case recurred. Four patients with derotation and mesenteric fan-shaped fixation recovered well without recurrence.Conclusion:Mesenteric fan-shaped fixation may be an effective operative type to reduce or avoid postoperative recurrence of mesenteric torsion.

OBJECTIVE: To evaluate the surgical methods for treating distal urethral stricture. METHODS: The clinical data of 80 patients with distal urethral stricture in Beijing Jishuitan Hospital, Captial Medical University between January 2018 and December 2022 were retrospectively collected. Including male genital lichen sclerosus (MGLS) 33 cases, iatrogenic injury 25 cases, postoperative hypospadias 12 cases, and other causes such as trauma 10 cases. Among these cases, strictures involved the urethral meatus in 54 instances, of which 38 were treated with meatotomy (MO), 7 with penile skin flap urethroplasty (PSFU), and 9 with oral mucosa graft urethroplasty (OMGU). There were also 26 instances where strictures involved both the navicular fossa and meatus; one case underwent PSFU while 25 underwent OMGU. Based on different surgical methods used for treatment purposes we divided the patients into MO group, PSFU group and OMGU group. The age of the three groups was (48.8±20.0) years, (53.3±21.8) years and (44.5±16.4) years. The mean±SD body mass index (BMI) was (28.6±3.9) kg/m², (29.6±3.2) kg/m² and (29.2±4.8) kg/m². The preoperative maximum flow rate was (5.8±2.3) mL/s, (6.8±2.4) mL/s and (5.7±3.1) mL/s. RESULTS: All the operations were successfully completed without Clavien Ⅲ or Ⅳ complications. The median length of strictures (measured intraoperatively) in the three groups were 1.1 (1.0, 1.6), 1.5 (1.1, 2.0) and 4.0 (2.5, 5.0) cm. The median operation time was 60.0 (60.0, 75.0), 85.0 (75.0, 112.5) and 180.0 (75.0, 330.0) min. The median estimated blood loss was 5.0 (2.0, 10.0), 15.0 (5.0, 42.5) and 180.0 (135.0, 216.3) mL. The median postoperative hospital stay was 3.5 (2.0, 5.0), 6.5 (3.5, 7.0) and 7.5 (7.0, 11.3) days. The median follow-up duration was 40.0 (26.3, 57.3), 55.0 (18.8, 62.8) and 52.5 (30.5, 64.0) months. The median postoperative maximum flow rate was 18.3 (15.5, 19.8), 19.2 (16.1, 20.1) and 17.2 (14.2, 19.6) mL/s. Among the 38 patients with MO, 33 cases had normal urination without reintervention, and 5 cases experienced recurrent strictures and required regular urethral dilation. Among the 8 patients with PSFU, 7 cases had normal urination without reintervention, and one case developed a urinary fistula, for which intervention was recommended but the patient opted to maintain the status quo. Among the 34 patients with OMGU, 28 cases had normal urination without reintervention. There were 6 instances of stenosis recurrence, with 5 cases requiring regular urethral dilations and one case requiring reconstructive surgery. The overall success rate of operation was 85.0%, and the reintervention rate was 15.0%. Statistical analysis revealed significant differences in etiologies among the three groups (P=0.002), as well as in stricture locations (P < 0.001), length of strictures (P < 0.001), operation time (P < 0.001), estimated blood loss (P < 0.001) and postoperative hospital stays (P < 0.001). However, no significant differences were observed in terms of age, BMI, history of previous urethral stricture surgeries, preoperative maximum flow rate, follow-up duration, postoperative maximum flow rate and reintervention rate. Univariate and multivariate Logistic regression analyses indicated that a history of previous urethral stricture surgeries was a risk factor for postoperative reintervention (P=0.026). CONCLUSION MO and PSFU are primarily suitable for treating short-segment (≤1.5 cm) distal penile urethral strictures, whereas OMGU is more appropriate for longer segment strictures. MO and OMGU can both be utilized in managing MGLS cases. PSFU and OMGU are more conducive to improving the appearance of the urethral meatus. The success rate of surgical management of distal penile urethral stricture is 85.0%, 15.0% of the patients still require surgical intervention after surgery, and having history of previous urethral stricture surgeries is a risk factor for postoperative reintervention.

Objective:To explore the clinical outcome of early endoscopic realignment with flexible cystoscope for pelvic fracture urethral injury.Methods:We retrospectively collected and analyzed the clinical data of patients with pelvic fracture urethral injuries in ER of Beijing Jishuitan Hospital from March 2018 to June 2022.Seventy-six male patients with PFUI were reviewed and 60 patients were included due to the integrity of data collected. The patients were divided into early endoscopic realignment (EER) group and suprapubic cystostomy (SC) group according to the acute management. There were 33 patients and 27 patients in EER group and SC group, respectively. The age of the patients were (42.2±13.8)years and (44.1±15.0) years in EER group and SC group, respectively. The causes of the injuries were car accident, falling and crush, the percentage of the patients were 60.6%(20 cases), 33.3%(11 cases), 6.1%(2 cases) and 55.6%(15 cases), 44.4%(12 cases), 0 in EER group and SC group, respectively. The difference between two groups was statistically insignificant. The procedure of EER began with a cystostomy guided by B ultrasound, then an antegrade cystoscopy was performed through the cystostomy while negociating the bladder neck to the proximal side of injured urethra. A ureteral stent was inserted into the broken urethra and retrieved by a forceps through retrograde urethroscopy with another flexible cystoscope. We inserted a guidewire into the ureteral stent before removing it and placed a 16F urethral catheter along the guidewire. We analyzed the difference between two groups including the incidence, the length and the management of urethral stricture and the complexity of urethroplasty if needed. The simple urethroplasty was defined as performing anastomosis after dissection of the bulbar urethral and removing the scar tissue, while the procedure was defined as complex urethroplasty if ancillary procedures, such as separating the corporal bodies and partial pubectomy, was needed.Results:The EER group and SC group had 33 patients and 27 patients, respectively. The mean operation time of EER was (24.5±7.0)minutes and there was no intra-operative complications. Postoperatively, 4 cases of bleeding and 2 cases of UTI were found, which were successfully treated by conservative managements. Twenty-eight out of 33 patients(84.8%) in EER group developed urethral stricture and the mean length of it was (3.10±1.20)cm. However, all patients in SC group developed urethral stricture (100.0%) with the mean stricture length of (3.83±1.18)cm. The difference between two groups in term of the length of stricture was statistically significant ( P=0.026). 24 patients(85.7%) in EER group were treated by urethroplsty, 2 patients(7.1%) with endoscopic urethrotomy and 2 patients (7.1%) with dilation. All were treated with urethroplasty but 2 patients with endoscopic in SC group. In EER group, 8 strictures (33.3%)finished with simple urethroplasty and 16 strictures (66.7%) with complex urethroplasty.While in SC group, 6 strictures(24.0%) completed with simple urethroplasty and 19 strictures (76.0%)with complex urethroplasty. The complexity of urethroplasty performed in EER group was not statistically significant when compared with it in SC group( P=0.538). Conclusions:The procedure of EER with flexible cystoscope is reliable and safe. Most patients with formed urethral stricture after PFUI would be treated with urethroplasty. EER can reduce the urethral stricture formation and may decrease the need of the ancillary procedures during the urethroplasties if needed.

Background At present, the evaluation of water quality in public swimming places mostly adopts the single index evaluation method, ignoring the possible correlation between the indicators, the problem of information overlap between the indicators, and the differences between the swimming places with single or multiple unqualified water quality indicators. Objective To evaluate water quality in public swimming places in Chongqing objectively, intuitively, and comprehensively. Methods In 2020, a stratified random sampling method was used to investigate seven water quality indicators of 112 public swimming places in the central urban area, the new downtown urban area, the northeastern area, and the southeastern area of Chongqing. The selected indicators were free residual chlorine, turbidity, pH, free residual chlorine in disinfection pool of feet, urea, total plate count, and coliform bacteria. Principal component analysis was utilized to comprehensively evaluate water quality of swimming places by calculating principal component characteristic values and comprehensive evaluation values. Results The qualification rates of free residual chlorine, turbidity, pH, free residual chlorine in disinfection pool of feet, urea, total plate count, and coliform bacteria were 91.30%, 89.40%, 91.30%, 91.30%, 99.00%, 95.20%, and 86.50%, respectively, and the P₅₀ values were 0.455 mg·L⁻¹, 0.59 NTU, 7.352, 6.63 mg·L⁻¹, 0.78 mg·L⁻¹, 8 CFU·mL⁻¹, and 0 CFU·100mL⁻¹, respectively. The results of principal component analysis showed that KMO=0.573, P<0.001; four principal components were extracted, the eigenvalues of each principal component were 2.990, 1.624, 0.854, and 0.617, respectively, and the cumulative contribution rate was 86.928%. The comprehensive values of Banan District, Beibei District, Bishan District, Fengdu County, Fengjie County, Jiangbei District, Nan'an District, Nanchuan District, Pengshui County, Qianjiang District, Rongchang District, Shizhu County, Tongnan District, Wanzhou District, Yongchuan District, Yuzhong District, Changshou District, and Zhongxian County were −0.139, 0.228, 0.587, 0.042, −3.365, 0.587, 0.597, 0.587, 0.587, 0.189, −1.127, −0.201, −0.181, 0.587, 0.416, 0.587, 0.587, −0.098, and 0.043, respectively. The comprehensive evaluation values (P₅₀) of the central urban area, the new downtown urban area, the southeastern area, and the northeastern area of Chongqing were 0.587, 0.587, −0.181, and 0.043, respectively. Conclusion The hygienic status of water in public swimming places in Chongqing is above average in China, but there are still potential health problems in turbidity and bacterial pollution in the southeastern area and Fengjie County of Chongqing.

Objective:To explore the effects of mind map-based multi-dimensional cardiac rehabilitation nursing model in patients with coronary heart disease (CHD) after percutaneous coronary intervention (PCI) .Methods:Totally 118 patients with coronary heart disease (CHD) who received PCI in Anhui No.2 Provincial People's Hospital from August 2020 to October 2021 were selected by convenience sampling. They were divided into a study group and a routine group by the envelop method, with 59 cases in each group. Patient in the routine group received routine cardiac rehabilitation nursing, while patients in the study group underwent the mind map-based multi-dimensional cardiac rehabilitation nursing on the basis of care provided to the routine group. The scores of Coronary Artery Disease Self-management Scale (CSMS) and Seattle Angina Questionnaire (SAQ) were compared between the two groups. A total of 118 questionnaires were distributed, and 4 patients who were lost to follow-up did not return to the hospital for re-examination on time (2 cases in the study group and 2 cases in the routine group) . Totally 114 valid questionnaires were recovered, and the effective recovery rate was 96.61% (114/118) .Results:After nursing, the emotional cognitive, treatment compliance, disease knowledge, and daily life management scores and total scores in CSMS in the study group were higher than those in the routine group, and the difference was statistically significant ( P<0.05) ; the scores of each dimension of SAQ were higher than those in the routine group, and the difference was statistically significant ( P<0.05) . Conclusions:The mind map-based multi-dimensional cardiac rehabilitation nursing model can improve the self-management ability and quality of life among CHD patients undergoing PCI, which is worth promoting in clinical practice.
