Objective:To explore effects of psychological resilience and social support on quality of life in patients undergoing ileal conduit surgery.Methods:Using the convenient sampling method, a total of 232 patients who underwent total cystectomy and ileal conduit surgery in Department of Urology in a Class ⅢGrade A general hospital from January 2014 to December 2018 were investigated by using the general data questionnaire, City of Hope Quality of Life-Ostomy Questionnaire (COH-QOL-OQ) , Perceived Social Support Scale (PSSS) and 10-item Connor Davidson Resilience Scale (CD-RISC-10) from March to August 2020.Results:The age of patients was (65.79±8.67) years old, the postoperative time was (42.14±15.76) months, the total score of quality of life was (263.28±28.71) , the score of social support was (71.81±8.02) and the score of psychological resilience was (31.27±5.27) . Multiple linear regression analysis showed that psychological resilience (β=0.18, P<0.01) , self-care (β=0.30, P<0.01) , age (β=0.18, P<0.01) , recurrent carcinoma (β=0.13, P<0.05) and self-paying (β=-0.21, P<0.05) were influence factors of quality of life of patients, which could explain the variability of 21.2%. Conclusions:A variety of factors affect quality of life of patients after ileal conduit surgery for a long time. Therefore, attention should be paid to continuing treatment and nursing, improving self-care ability and psychological quality, promoting quality of life and improving disease outcomes.

Objective:To explore the effects of the LEARNS model in health education of urinary incontinence for patients undergoing laparoscopic radical prostatectomy.Methods:From September 2019 to August 2020, totally 60 patients who underwent laparoscopic radical prostatectomy in the Department of Urinary Surgery, Peking University First Hospital were selected by convenience sampling and divided into a control group and an intervention group according to the time of admission, with 30 cases in each group. Patients in the control group underwent conventional health education, while patients in the intervention group received nursing using the LEARNS model, with specific steps including listen (L), establish (E), adopt (A), reinforce (R), name (N), and strengthen (S). The mastery of knowledge about pelvic floor muscle before discharge was compared between the two groups, and the urinary continence of the two groups at 1 and 3 months after discharge was observed.Results:The knowledge level and correctness of pelvic floor muscle in the intervention group were higher than those in the control group, and the differences were statistically significant ( P<0.01). At 3 months after surgery, the urinary incontinence score of the intervention group was lower than that of the control group; the number of urine pads used was less than that of the control group; the rate of continence was higher than that of the control group, with statistically significant differences ( P<0.01) . Conclusions:The LEARNS mode can effectively improve the mastery of knowledge about pelvic floor muscle in patients undergoing laparoscopic radical prostatectomy, and improve their postoperative urinary continence.

Objective:To explore the influencing factors of the poor sustainability of the evidence-based practice project for irritant dermatitis around urostomy.Methods:This is a qualitative study. From April to May 2020, 12 nurses working in the Urology Surgery of Peking University First Hospital were selected by purposive sampling for the semi-structured interview. The integrated-Promoting Action on Research Implementation in Health Services framework (i-PARIHS framework) was applied to analyze and extract the obtained data.Results:The interview results found that, in terms of transform (evidence) , the localization and continuity of evidence for the evidence-based practice project of irritant dermatitis around urostomy needed to be improved, including the high matching between evidence and practice environment, and the insufficient continuity of evidence application. In terms of transform recipients, the leadership of project practitioner needed to be improved, including the conflict between the roles of practitioners and researchers, the lack of knowledge reserves of practitioners, and the conflict among the values of practitioners. In terms of organizational environment, the leadership of managers and the imformatization degree of project needed to be improved, including insufficient support from leaders and insufficient facilities.Conclusions:At the initial stage of formulating the nursing evidence-based practice project, the project implementer should fully incorporate the opinions of stakeholders for localization debugging, and consider the sustainability of the project. In addition, the leadership of managers, nurses and interns should be increased, the use and training of urostomy talents should be strengthened, the training of urostomy knowledge should be continued, the information-based follow-up system should be improved, and the intervention strategy should be continuously adjusted to ensure the project is carried out.

Objective:To explore the predictive value of preoperative pelvic floor electromyography(EMG)parameters for the risk of urinary incontinence after prostate cancer surgery.Methods:This study retrospectively analyzed the medical records of 271 patients who underwent radical prostatectomy in the urology department of Peking University First Hospital from January 2020 to October 2022.The data included patient age,body mass index(BMI),international prostate symptom score(IPSS),prostate-specific antigen(PSA)levels,Gleason score,type of surgery,urethral reconstruction,lymph node dis-section,nerve preservation,catheterization duration,D'Amico risk classification,American Society of Anesthesiologists(ASA)score,Charlson comorbidity index,postoperative duration,prostate volume,and pelvic floor EMG parameters(pre-resting mean,fast muscle mean,and slow muscle mean scores).Independent risk factors affecting early postoperative urinary incontinence were identified through multiva-riate Logistic regression analysis.The predictive efficacy of pelvic floor EMG results was evaluated by cal-culating the area under the receiver operating characteristic(ROC)curve,and the optimal threshold for early postoperative urinary incontinence was determined based on the Youden index and clinical signifi-cance.Results:The study included 271 prostate cancer patients,with an 81.9％rate of voluntary urinary control post-surgery.The median score for fast pelvic floor muscles was 23.5(18.2,31.6),and for slow muscles,it was 12.5(9.6,17.3).Among the patients,179(66.1％)did not preserve nerves,and 110(40.6％)underwent urethral reconstruction.Advanced age and low fast muscle scores were identified as independent risk factors for urinary incontinence.Patients aged ≤60 had 5.482 times the voluntary urinary control rate compared with those aged ≥70(95％CI:1.532-19.617,P＜0.05).There was a significant correlation between fast muscle scores and urinary incontinence recovery(OR=1.209,95％CI:1.132-1.291,P＜0.05).When the optimal threshold for preoperative fast muscle score was set at 18.5,the ROC sensitivity and specificity were 80.6％and 61.2％,respectively.Con-clusion:Preoperative pelvic floor EMG parameters show good predictive accuracy and clinical applicabili-ty for the risk of urinary incontinence after prostate cancer surgery.These parameters can be used for ear-ly identification of urinary incontinence risk,with age and fast muscle scores being important predictors.

Objective To explore the barriers in the clinical use of evidence-based urethral catheter cleaning. MethodsThe interview outline was developed based on the Theoretical Domains Framework (TDF) from September to October 2018. Totally 19 nurses working in the Department of Urinary Surgery at Peking University First Hospital was selected for semi-structural interview by convenient sampling, and content analysis was conducted based on the results. ResultsA total of 4 barriers related to 4 domains under the TDF were found in this study, namely, social / professional roles and identities, confidence in results, environmental factors and resources, and social impact. The subjects were extracted on this basis, which were lack of knowledge conversion process and norms in the department, poor self-management ability in the patients, and insufficient catheter cleaning resources. ConclusionsThe clinical use of evidence-based urethral catheter cleaning is affected by multiple factors, including systems, patients and resource availability. Departments need to explore and develop the norms for knowledge transformation, improve the self-management ability of postoperative patients, provide sufficient resources for catheter cleaning, and promote the clinical use of evidence-based urethral catheter cleaning.

Objective:To find out the obstacle factors in its clinical application according to the clinical situation of the application of urinary catheter fixation device.Methods:From September 2018 to October 2018, 19 nurses working in the urology ward of Peking University First Hospital were selected for a semi-structured interview. Based on the theoretical domain framework, the interview outline was formulated and the content was analyzed, and the topic was extracted again.Results:This study identified obstacle factors related to 5 areas of the theoretical domain framework, namely "knowledge, social or professional role and identity, motivation and goals, environmental factors and social influence". The themes were extracted again, respectively: "the system level of evidence implementation (organizational factors, training, product categories) needs to be optimized, the level of willingness of users (patients) for evidence implementation needs to be improved and the sustainability of evidence application needs to be strengthened".Conclusions:The factors that affect the clinical application of urinary catheter fixation devices are multiple, and future research needs to formulate targeted intervention plans based on evidence according to obstacles identified.

The permanent or temporary stoma left in patients undergoing neostomy affects the patients both physiologically and psychologically. The Registered Nurses Association of Ontario (RNAO) released the clinical practice guidelines of Supporting Adults Who Anticipate or Live with an Ostomy, second edition in 2019. This article interprets the recommendations of this guideline, and focuses on preoperative and postoperative care planning, parastomal hernia prevention, and the quality of life of patients undergoing neostomy, in order to provide clinical practitioners with effective stoma care advice.

Objective:To investigate the safety and efficacy of pulsed Thulium fiber laser enucleation (ThuFLEP) in the treatment of benign prostatic hyperplasia (BPH).Methods:Clinical data of 238 BPH patients who underwent ThuFLEP from November 2022 to November 2023 at Peking University First Hospital were retrospectively analyzed. Patients were divided into two groups based on different surgical techniques: 199 patients underwent traditional continuous-wave Thulium fiber laser prostatectomy (C-ThuFLEP group), and 39 patients underwent Thulium fiber laser enucleation with pulse modulation (P-ThuFLEP group). Propensity score matching was used to balance baseline characteristics between the two groups. Operative time, resected tissue weight, pre- and postoperative hemoglobin decrease, postoperative hospital stay, and postoperative catheterization time were recorded and compared between the matched groups. Intraoperative and short-term postoperative complications were also recorded and compared between the two groups. Follow-up assessments at 1 month postoperatively were conducted to compare the maximum urinary flow rate (Q max), international prostate symptom score (IPSS), international index of erectile function (IIEF-5) score, quality of life (QOL) score, and International Consultation on Incontinence Questionnaire Short Form (ICIQ-SF) score between the two groups, as well as changes in Q max and IPSS, IIEF-5, and QOL before and after surgery. Results:After matching, a total of 60 patients were included, with 30 patients in each group. There were no statistically significant differences between the two groups in terms of age [(68.73±6.91) years vs. (71.07±7.34) years], American Society of Anesthesiologists (ASA) score (1-2/3-4: 23/7 vs. 23/7), comorbidity count (0-1/>1: 15/15 vs. 15/15), prostate volume [68.3 (50.0, 105.3) ml vs. 63.3 (45.7, 106.0) ml], preoperative IPSS score [24 (21, 29) vs. 23 (14, 26)], IIEF-5 score [5 (0, 15) vs. 5 (0, 13)], and QOL score [5 (4, 6) vs. 5 (5, 6)] (all P>0.05). The tissue removal rate in the P-ThuFLEP group was higher than that in the C-ThuFLEP group [0.82 (0.71, 1.18) g/min vs. 0.72 (0.46, 0.95) g/min, P=0.026], while there were no statistically significant differences between the two groups in operative time [47 (37, 79) min vs. 65 (33, 87) min], resected tissue weight [45 (31, 75) g vs. 33 (22, 65) g], postoperative hemoglobin decrease [17 (10, 23) g/L vs. 12 (7, 19) g/L], postoperative hospital stay [4 (3, 5) days vs. 4 (3, 5) days], and postoperative catheterization time [3 (3, 5) days vs. 3 (3, 6) days]. The incidence of intraoperative complications in both groups was 10% (3/30), with no statistically significant difference ( P=1.000), and no severe complications of grade Ⅲ or above occurred. There were no statistically significant differences in Q max [24 (15, 33) ml/s vs. 16 (10, 32) ml/s], IPSS score [14 (12, 15) vs. 9 (7, 12)], QOL score [2 (1, 3) vs. 2 (1, 3)], and IIEF-5 score [3 (0, 5) vs. 3 (0, 6)] between the C-ThuFLEP and P-ThuFLEP group at 1 month postoperatively (all P > 0.05), and both showed significant improvement compared to preoperative values (all P < 0.05). The ICIQ-SF score in the P-ThuFLEP group was lower than that in the C-ThuFLEP group [0 (0, 4) vs. 4 (3, 8)], with a statistically significant difference ( P=0.033). Conclusions:Compared with traditional continuous-wave Thulium fiber laser prostatectomy, pulse-modulated Thulium fiber laser enucleation demonstrates higher efficiency in tissue removal, lower early postoperative ICIQ-SF score for urinary incontinence, similar risk of intraoperative complications, and can be safely and effectively applied in the surgical treatment of BPH patients.

Objective:To investigate the therapeutic effectiveness and safety of "U shape" en bloc Thulium fiber laser enucleation and resection of the prostate (ThuLERP) technique.Methods:The clinical data of 105 benign prostatic hyperplasia (BPH) patients treated by a single surgeon in Peking University First Hospital from January to October 2022 were retrospectively reviewed. Among them, 50 patients underwent "U-shaped" en bloc technique prostate enucleation (UEBT), and 55 patients underwent prostate lobe removal using the lobe technique (LT). There were no significant differences between UEBT and LT groups ( P>0.05) in term of the age[(69.1±6.9)years old vs.( 68.8±9.1)years old], international prostate symptom score(IPSS)[(22.7±1.9)vs.(22.8±2.7)] and maximum flow rate(Q max ) [(9.0±3.7)ml/s vs.(9.3±4.3)ml/s]. The prostate-specific antigen(PSA) of UEBT group was higher than that of LT group[7.52(3.05, 8.76)ng/ml vs.6.78(1.61, 7.45)ng/ml], and the prostate volume of the UEBT group was larger than that of LT group [(103.49±46.19)ml vs.(75.73±30.69) ml, all P<0.05]. In the UEBT group, the apical of prostate was bluntly enucleated with pre-transection urethral mucosa at the apex of prostate technique. Secondly, glands formed grooves at 12 o'clock after vaporization, which served as anatomical marker. At last, the whole lobe which was like "U shape" were resected using laser. In the LT group, glands was divided to three lobe, the middle, the left and the right lobe was bluntly enucleated respectively. Perioperative data, postoperative complications and clinical outcomes were compared between the two groups. Correlation between enucleation efficiency and enucleation weight was analysed using linear regression. Results:There were no significant differences between the UEBT and LT group ( P>0.05) in term of morcellation time[18(9, 34)min vs.16(8, 28)min], resection rate[(0.5±0.1)g/ml vs.(0.5±0.1)g/ml], catheter indwelling duration[(3.8±1.4)d vs.(3.6±1.1)d] and hospitalization stay[(4.1±0.3)d vs.(3.9±0.8)d].The difference between the UEBT group and LT group in operation time[54(42, 100)min vs.80(60, 150)min], enucleated time[37(26, 75)min vs.47(31, 69)min], hemostasis time[4(3, 6)min vs.9(7, 15)min], enucleation efficiency[(1.8±0.5)g/min vs.(1.1±0.4)g/min] and hemoglobin decline[13(9, 22)g/L vs.17(10, 22)g/L]were statistically significant ( P<0.05). In both groups, postoperative IPSS were (6.6±1.7) and (6.2±1.4) respectively, and Q max were(18.9±3.1)ml/s and (16.8±3.8)ml/s respectively, which were significantly different from that before the operation ( P<0.05). However, there was no significant difference between the two groups ( P>0.05). The enucleation efficiency increased with the increase of prostate volume( r=0.791, 0.880 respectively, P<0.05).After 2 weeks of follow up the postoperative immediate urinary continence rate of UEBT group and LT group were 10.0%(5/50)and 27.3%(15/55), respectively, and the two groups had statistical differences ( P<0.05). But after 3 months of follow up, there was no urinary continence in the two groups, and incidence of postoperative urethral stricture were 2.0%(1/50) and 5.5%(3/55) respectively in UEBT and LT group, whose difference was not significant( P>0.05). Conclusions:ThuLERP can relieve lower urinary tract symptoms in a comparable way with high efficacy and safety. ThuLERP with the "U-shaped" en bloc technique was statistically superior to the lobe technique in operation time, enucleation time, enucleation efficiency, hemoglobin decline and also avoided stress urinary incontinence at early stage after operation.
