Objective To evaluate the efficacy and complications of flexible ureteroscopy for the treatment of upper urinary tract calculi in children.Methods The clinical data of upper urinary tract calculi in 20 children including 16 male and 4 female,treated by using flexible ureteroscopy,were collected from January 2014 to May 2015 in the First Affiliated Hospital of Zhengzhou University.The mean age was 6.4 years (ranging from 2.7-15.0 years old).Among them,6 cases had upper ureteral calculi and 14 cases had renal calculi.All the calculi was found unilaterally with on the left side in 12 cases and on the right side in 8 cases.Ipsilateral mild to moderate hydronephrosis were found in all of the cases.The mean stone size was 1.2 cm (ranging from 0.5-1.8 cm).All the cases were treated through retrograde flexible ureteroscopy holmium laser lithotripsy after the invalid conservative through conservative treatment.Double J tube was left routinely in the sick side 1 week before operation to expand the internal diameter of the ureter.A double J stent was left in place for 1 month after operation as a routine.Results The flexible ureteral access sheath failed to insert into the upper ureter in 2 cases because of the narrow ureter,then the flexible ureteroscopy was inserted into ureter through wire directly.The flexible ureteral access sheath was successfully inserted into the ureter for the others and flexible ureteroscopy were inserted through flexible sheath.The mean operative time was 38 min (ranging from 20-60 min).The patients were discharged from hospital after a mean of 4.5 days (ranging from 3-7 days).The rate of stone-free in one-stage was more than 90％.There were residual small stones in the lower calices of kidney in 2 cases.The perfusion liquid volume during the operation was 500 mL(ranging from 200-1 000 mL).There was no major perioperative complication,while transient macroscopic hematuria and fever were common complications after operation.The stone search was performed successfully in the whole 14 cases.NO residual stone could be found through ultrasound and kidney ureter bladder plain and Double-J stent was removed 1 month after operation.Conclusions Flexible ureteroscopy produces high stone-free rate and clinical safety for upper urinary calculi in children.However,the complications of flexible ureteroscopy lithotripsy cannot be ignored and sufficient preoperative preparation and careful perioperative safety control should be required.

Objective:To investigate the post-traumatic growth status of patients with urinary bladder cancer after surgery and analyze its influencing factors.Methods:Using the convenient sampling method, a total of 289 patients with urinary bladder cancer who were admitted to the First Affiliated Hospital of Zhengzhou University from January to December 2019 were selected as the research objects. The general data questionnaire, Post-traumatic Growth Inventory and Psychological Resilience Scale were used for investigation. Multiple linear regression was used to analyze the influencing factors of post-traumatic growth of patients with urinary bladder cancer after surgery.Results:Post-traumatic growth score of patients with after surgery was (61.47±10.79) . Differences in post-traumatic growth scores of urinary bladder cancer patients after surgery with different ages, residences, education levels, medical payment methods, average monthly family income, degree of self-care and metastasis were statistically significant ( P<0.05) . The total score of psychological resilience and scores of various dimensions of patients with urinary bladder cancer after surgery were positively correlated with the post-traumatic growth score ( P<0.05) . The results of multiple linear regression analysis showed that psychological resilience, education level and average monthly family income were the main factors influencing post-traumatic growth of patients with urinary bladder cancer after surgery ( P<0.05) . Conclusions:Post-traumatic growth of patients with urinary bladder cancer after surgery is at a medium level. Educational level, average monthly family income and psychological resilience are the main factors affecting post-traumatic growth of patients, suggesting that nursing managers can improve the post-traumatic growth of patients with urinary bladder cancer after surgery through intervention of influencing factors.

Objective:To explore status of quality of life of elderly patients with benign prostatic hyperplasia and analyze the influencing factors.Methods:A total of 300 elderly patients with benign prostatic hyperplasia who were admitted to the First Affiliated Hospital of Zhengzhou University from September 2018 to October 2019 were selected as the research subjects by the convenient sampling method. The general information questionnaire, Benign Prostatic Hyperplasia Patients Quality of Life Scale and Health Behavior Ability Self-Rating Scale were used to investigate. Pearson correlation analysis method was used to analyze the correlation between health behavior and quality of life in elderly patients with benign prostatic hyperplasia. Multiple linear regression was used to analyze the factors affecting quality of life of elderly patients with benign prostatic hyperplasia. In this study, a total of 300 questionnaires were distributed, and 289 valid questionnaires were returned. The effective response rate was 96.33%.Results:The score of the Benign Prostatic Hyperplasia Patients Quality of Life Scale for 289 elderly patients with benign prostatic hyperplasia were (106.83±20.27) , and score of Health Behavior Ability Self-Rating Scale was (56.19±18.64) . Univariate analysis showed that there were statistically significant differences in scores of Benign Prostatic Hyperplasia Patients Quality of Life Scale for patients with different age, education background, marital status, family per capita monthly income, residence, disease course and other chronic diseases ( P< 0.05) . The results of Pearson correlation analysis showed that the health behavior of elderly patients with benign prostatic hyperplasia was positively correlated with the quality of life ( P<0.01) . The results of multiple linear regression analysis showed that educational background, healthy behavior ability and marital status were influencing factors of quality of life of elderly patients with benign prostatic hyperplasia ( P<0.01) , a total of 40.4% of the total variation was explained. Conclusions:The quality of life of elderly patients with benign prostatic hyperplasia is not high, and the educational background, health behavior ability and marital status can affect the quality of life of patients. It is recommended that clinical nursing workers take targeted and effective measures to improve the quality of life of elderly patients with benign prostatic hyperplasia.

Objective:To probe into the influence of adhesive tape and string fixation on postoperative catheter-associated urinary tract infection(CAUTI) and comfort degree of patients undergoing percutaneous nephrolithotomy.Methods:A total of 106 cases of male urinary tract calculi patients undergoing percutaneous nephrolithotomy in Urology Department of First Affiliated Hospital of Zhengzhou University from January 2018 to April 2019 were selected. They were divided into the experimental group (55 cases) and the control group (51 cases) by random digits tbale method. The control group received platform fixation method, the experimental group implemented adhesive tape and string fixation method for catheter fixation. The incidence of CAUTI were compared between two groups, the catheter exposed length changes and catheter-related discomfort changes was also compared.Results:The incidence of CAUTI were 3.9%(2/51) in the experimental group, significantly lower than 16.7%(8/48) in the control group, the difference was statistically significant ( χ2=4.42, P<0.05). After 3 days, 5 days and 7 days of indwelling catheter, the catheter exposed length were (17.76 ± 1.41), (17.12 ± 1.28), (16.49 ± 1.63) cm, significantly longer than those in the control group (16.04 ± 1.96), (15.81 ± 1.78), (15.29 ± 1.96) cm ( t=5.00, 4.17, 3.32, all P<0.05); the catheter-related discomfort symptom scores at above mentioned time were 0.82 ± 0.09, 0.53 ± 0.07, 0.49 ± 0.08, significantly lower than those in the control group (1.17 ± 0.23, 0.92 ± 0.09, 0.77 ± 0.11), the differences were statistically significant ( t=2.10, 2.88, 2.46, all P<0.05). Conclusions:Adhesive tape and string fixation method for catheter fixation can reduce the incidence of CAUTI of patients with urinary tract calculi, improve the catheter fixed state as well as reduce the patient′s catheter-related discomfort.
