“…The learning curve for the method is minimal and simple. The primary disadvantages of the holmium laser, however, are its expensive apparatus, expensive ber, and longer lithotripsy times [50,51]. The holmium laser may also break all components of stone while causing little heat damage.…”

Backgrounds To compare the effectiveness and safety of high-power (100 W) vs. low-power (20 W) laser settings for transurethral laser lithotripsy in the treatment of urethral stones. Methods The trial was open to all patients scheduled for transurethral holmium laser lithotripsy who had urethral stones with the maximal diameter. Either the low-power laser setting or the high-power laser setting was applied to every substitute patient. Using IBM SPSS Statistics 24, we compared the treatment groups' operational times, intraoperative/postoperative problems (up to 1 year), and stone-free rates. Welch tests were used to compare continuous data across treatment groups, whereas Fisher's exact or Chi-square tests were used to evaluate categorical variables. Statistical significance was defined as a p value 0.05. Results Two hundred seven people were hired as a result. Both groups' preoperative data and mean bladder stone sizes were similar. When compared to the low-power cohort, the procedure took much less time—42.6111.74 min as opposed to 78.5625.91 min (p = 0.025)—and the ablation rate was significantly higher in the high-power cohort. In neither group were there any substantial intraoperative issues. High power group considerably outperformed low power group in terms of OABSS score and IPSS. According to results of uni- and multivariate logistic regression, the position of the ureteral stone significantly affects how well the therapy works. Conclusion When treating urethral stones, a high-power laser setting of up to 100 W significantly reduces the length of the procedure without increasing the risk of complications.

Therapeutic Advances in Urology

While urolithiasis in children is rare, the global incidence is rising, and the volume of minimally invasive surgeries being performed reflects this. There have been many developments in the technology, which have supported the advancement of these interventions. However, innovation of this kind has also resulted in wide-ranging practice patterns and debate regarding how they should be best implemented. This is in addition to the extra challenges faced when treating stone disease in children where the patient population often has a higher number of comorbidities and for example, the need to avoid risk such as ionising exposure is higher. The overall result is a number of challenges and controversies surrounding many facets of paediatric stone surgery such as imaging choice, follow-up and different treatment options, for example, medical expulsive therapy, shockwave lithotripsy, ureteroscopy, and percutaneous nephrolithotomy. This article provides an overview of the current status of paediatric stone surgery and discussion on the key topics of debate.

Objectives: To construct a predictive model of nosocomial infection in patients with upper urinary tract (UUT) stones after flexible ureterorenoscopy with laser lithotripsy (FURSLL). Methods: Medical records of 196 patients with UUT stones who underwent FURSLL in Suzhou Hospital of Integrated Traditional Chinese and Western Medicine from December 2019 to December 2022 were retrospectively analyzed. Patients were divided into infected group or uninfected group based on the presence of infection during postoperative hospitalization. Univariate and multivariate logistic regressions were used to identify risk factors of postoperative nosocomial infections. A nomogram prediction model was constructed using R software. The predictive ability of the model was assessed using the receiver operating characteristic (ROC) curve. Results: A total of 54 patients (27.6%) developed nosocomial infections after FURSLL. Logistic regression analysis showed that older age, diabetes, preoperative urinary system infection, ureteral stricture, hydronephrosis, double J-stent retention time, and stone diameter were risk factors of nosocomial infection. The nomogram model was constructed based on these risk factors. The ROC showed that the area under the curve (AUC) of the model was 0.930 (95% CI: 0.890-0.970), and the sensitivity and specificity were 92.6% and 81.7%, respectively, indicating that the prediction model was effective. Conclusions: Risk of nosocomial infection in patients with UUT stones after FURSLL is affected by older age, diabetes, preoperative urinary system infection, ureteral stenosis, hydronephrosis, double J-stent retention time, and stone diameter. The nomogram prediction model, constructed based on the above factors, has good predictive value. doi: https://doi.org/10.12669/pjms.40.3.8855 How to cite this: Xu Y, Xu P.
