Percutaneous Nephrolithotomy Versus Open Surgery in the Treatment of Urinary Calculi.

Objective: To evaluate the effectiveness of percutaneous nephrolithotomy (PCNL) compared with open surgery for urinary stone removal. Methods: A total of 95 patients with urinary stones were screened for eligibility between October 2020 and December 2021. After excluding 5 patients who revoked their consent, 90 patients were randomized to receive either traditional open surgery (traditional group) or PCNL (PCNL group), with 45 patients in each group. In addition, the two groups received Shugan Qingre Tonglin decoction twice daily for 2 weeks. Outcome measures included intraoperative indexes, stone removal rate, postoperative healing, and quality of life. Results: PCNL resulted in significantly better intraoperative indexes (95% CI, 0.49-1.11; P < .001), lower creatinine concentration (95% CI, 0.59-1.61; P < .001), and higher glomerular filtration rate (95% CI, 2.43-2.91; P < .001) compared with traditional open surgery. Patients in the PCNL group had a significantly higher stone removal rate (95% CI, 1.09-2.51; P < .001) and a lower incidence of adverse events (95% CI, 0.69-1.87; P < .001) compared with those receiving traditional open surgery. Patients in the PCNL group had significantly higher quality of life (95% CI, 1.39-2.81; P < .001) and significantly higher maximum urinary flow rate (95% CI, 1.36-2.61; P < .001) than those in the traditional group at 1 month and 3 months after treatment. Conclusion: PCNL provides better postoperative renal function improvement, enhances the postoperative recovery of patients with urinary stones, and features manageable safety compared with traditional open surgery. The benefits of PCNL make it a promising technique for the clinical management of urinary stones. Its minimally invasive nature reduces patient discomfort, promotes faster recovery, and improves overall patient satisfaction. The superior outcomes of PCNL in terms of renal function improvement and postoperative recovery suggest that it is a viable alternative to traditional open surgery. Further research and clinical trials are warranted to validate these findings and establish PCNL as a widely adopted approach in the field of urology.

The effect of the use of postoperative antibiotic prophylaxis compared with non-use for stented distal hypospadias repair wound: A meta-analysis.

A meta-analysis investigation to measure the influence of the usage of postoperative antibiotic prophylaxis (POP) compared with non-usage for stented distal hypospadias repair (SDHR). A comprehensive literature inspection till February 2023 was applied and 1067 interrelated investigations were reviewed. The 10 chosen investigations enclosed 1398 individuals with SDHR in the chosen investigations starting point, 812 of them were using POP, and 586 were not using POP. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the effect of the usage of POP compared with non-usage for SDHR by the dichotomous and continuous approaches and a fixed or random model. No significant difference was found between individuals using POP and not using POP in posthypospadias repair problem (PRP) (OR, 0.99; 95% CI, 0.42-2.34, P = .97) with moderate heterogeneity (I2 = 69%), posthypospadias repair infection problem (PRIP) (OR, 0.56; 95% CI, 0.30-1.06, P = .08) with no heterogeneity (I2 = 15%), and overall composite posthypospadias repair wound healing associated problem (OCPRWHAP) (OR, 1.27; 95% CI, 0.61-2.63, P = .53) with moderate heterogeneity (I2 = 59%) for SDHR. No significant difference was found between individuals using POP and not using POP in PRP, PRIP, and OCPRWHAP for SDHR. However, cautilised of the small sample sizes of several chosen investigations for this meta-analysis, care must be exercised when dealing with its values, for example, the low P-value of the PRIP.

Laparoscopic treatment of bilateral duplex kidney and ectopic ureter: A case report.

BACKGROUND: Duplication of the renal pelvis is a common congenital malformation of the urinary system. About one-third of cases are complete unilateral duplication of the renal pelvis, while bilateral duplication is extremely rare. Herein, we described a single case of bilateral renal duplication with double ureteral orifice ectopic vaginal fistula treated with laparoscopy. CASE SUMMARY: A 6-year-old girl suffering from long-term vaginal leakage was admitted on June 10, 2018. She was diagnosed with complete duplication of both kidneys and ureters and ectopic opening of both ureters combined with ureterovaginal fistula. The patient received laparoscopic ectopic ureteral bladder replantation and was followed up for 2 years. No renal function damage and vaginal leakage were found. CONCLUSION: Laparoscopic bladder-ureter reimplantation could effectively determine the location and number of ectopic ureters by imaging and cystoscopy.

Exploration of standardized clinical skills instruction video based on QR code management in clinical hospital teaching.

OBJECTIVE: To explore the application effect of standardized clinical skills instruction video based on QR code management in clinical teaching to promote the information reform and innovation of clinical teaching and seek a new practice method with a higher teaching efficiency. METHODS: A total of 150 clinical, medical-technical, and nursing interns who completed their internship in our hospital by June 2021 after being enrolled in 2020 were assigned to the experimental group, and 84 interns who completed their internship by June 2020 after being recruited in 2019 were retrospectively included in the control group. The experimental group received standardized clinical skills instruction videos based on QR code management to clinical teaching, while the control group was given the traditional teaching method. The costs of teaching models, materials management, and human resources in the clinical skills center that were eventually consumed by the two groups were counted, and the satisfaction of the interns and teachers towards teaching activities was investigated by a satisfaction questionnaire. In addition, the scores of the final exam of internship skills and the pass rate of the enrollment skill exam for residency training were compared between the two groups. RESULTS: After the application of standardized clinical skills instruction videos based on QR code management to clinical teaching, the cost of running the clinical skills center was significantly reduced ($800 vs. $10,000), and the intern trainees (χ2=10.088, P=0.0064) and teachers (χ2=6.1138, P=0.0470) who received these videos expressed higher satisfaction than those given the traditional teaching model, with better performance on the final exam of internship skills (t=11.952, P=0.0000) and a higher pass rate of the enrollment skills exam for residency training (χ2=6.402, P=0.0114). CONCLUSION: The standardized clinical skills instruction video based on QR code management can realize the synchronization of classroom teaching and network teaching and the decentralized network-independent learning, which promotes the information reform and innovation of clinical hospital teaching based on the integration of multimedia teaching and network learning and provides a novel practice method with a higher effect for clinical hospital teaching.

Upregulation of cell adhesion through delta Np63 silencing in human 5637 bladder cancer cells.

Some researchs have demonstrated that the loss of delta Np63 is associated with aggressive phenotypes and poor prognosis. However, other research indicates that delta Np63 is considered to have oncogenic properties. Delta Np63 overexpression is often observed in association with the oncogenic growth of squamous cell carcinomas and bladder cancer. In this study, we investigated the oncogenic role of delta Np63 in regulating cell adhesion in transitional cell carcinoma of the bladder (TCCB). The cells were stably transfected with the delta Np63 short hairpin RNA (shRNA) plasmid. Immunocytochemistry was performed to determine the knockdown efficiency. Tumour cells were studied for their ability to adhere to vascular endothelial cells. Confocal microscopy was used to analyse the changes in cytoskeletal F-actin. F-actin expression was measured by flow cytometry. Cell invasion ability was assessed using transwell chambers. The delta Np63-silenced tumour cells were shown to adhere more tightly than controls to vascular endothelial cells (P<0.05). The content of F-actin in the delta Np63-silenced cells was enhanced (P<0.05). The Matrigel invasion assays showed that human 5637 bladder cancer cells had a lower degree of motility when transfected with pdelta Np63-shRNA (P<0.05). In conclusion, silencing of the delta Np63 expression can enhance the adhesiveness of 5637 cells by inducing F-actin cytoskeleton production, and it will possibly inhibit the TCCB invasion and metastasis.
