Purpose: To compare the efficacy of different treatment strategies for distal ureteral stones smaller than 10 mm.
Material And Methods: A total 127 patient were included in the study. Based on the treatment modality , patients were divided into three groups.Patients in group 1 only received conventional treatment including daily hydration of 2500 mL, ciprofloxacin, diclofenac sodium and a spasmolytic agent; group 2 patients received conventional treatment (daily hydration of 2500 mL, ciprofloxacin, diclofenac sodium and a spasmolytic agent) and tamsulosin 0.4 mg orally daily for 4 weeks; and group 3 patients underwent ureteroscopy. Patients were further subdivided into 2 categories based on maximum stone diameter: category A (less than 5 mm) and category B (5.0-9.9 mm). Following treatment, all groups were compared in terms of stone-free rate and time to expulsion.
Results: Following treatment, the stone-free rates for groups 1, 2 and 3 were 48.7%, 59.5% and 95.6%, respectively (P < .0001).The mean expulsion times for groups 1, 2 and 3 were 15.3 ± 5.33, 15.1 ± 5.5 and 1.95 ± 2.2 days, respectively (P < .001). Compared to the other treatments, the stone-free rate and mean expulsion time in the ureteroscopy group were significantly increased and decreased, respectively.
Conclusion: There are several treatment options for distal ureteral stones. Based on our data,we conclude that ureterorenoscopy should be the standard of care for distal ureteral stones smaller than 10 mm.

Stone-event-free survival after retrograde intrarenal surgery: is the stone-free-status so relevant for the future outcomes?

Introduction: The primary aim of stone treatment is to achieve stone-free status. Residual fragments can cause stone growth, recurrence, urinary tract infections, and ureteric obstruction. Our goal was to describe the natural history of stone burden after retrograde intrarenal surgery (RIRS) based on stone-free status (SFS), evaluating stone growth and stone-events.

Introduction And Aim: The main categories of drugs employed for medical expulsive therapy in patients with ureteral calculi (UC) are alpha-blockers (α-B) and beta-adrenoceptor agonists. This meta-analysis evaluated the safety and effectiveness of α-B versus mirabegron (MIR) in treating UC.
Methods: From January 1980 to October 2024, we extensively searched the Pubmed, Web of science, Cochrane and EMBASE databases to identify randomized controlled trials (RCTs) that compared the effectiveness of α-B and MIR in managing UC.
Comparison of three different scoring systems in predicting success of retrograde intrarenal surgery in kidney stones larger than 20 millimeters.

Purpose: To evaluate stone free rate (SFR) predictivity of three different scoring systems in patients with kidney stones larger than 20 millimeters undergoing retrograde intrarenal surgery(RİRS).
Methods: Digital records of a total of 166 patients were reviewed retrospectively. Epidemiological characteristics (age, gender, medical history) of the patients, stone and affected kidney characteristics (size, volume, location, density, opaque, presence of urinary system anomaly, presence of stones in different calyx, number of stones, lower pole stone, renal infundibulopelvic angle (IPA), renal infundibulopelvic length (RIL), hydronephrosis), and operative characteristics (preoperative ureteral stent, operation duration, postoperative residual fragments, hospitalization time and complications were recorded.

Employing advanced machine learning models, we aim to identify biomarkers for urolithiasis from 24-h metabolic urinary abnormalities and study their associations with urinary stone diseases. We retrospectively recruited 468 patients at Peking Union Medical College Hospital who were diagnosed with urinary stone disease, including renal, ureteral, and multiple location stones, and had undergone a 24-h urine metabolic evaluation. We applied machine learning methods to identify biomarkers of urolithiasis from the urinary metabolite profiles.

Purpose: To evaluate the effectiveness and safety of an upgraded integrated vacuum suction catheter in semi-rigid ureteroscopic laser lithotripsy (VC-URSL) compared to traditional methods for treating impacted upper ureteral stones.
Patients And Methods: This prospective, randomized controlled trial was conducted from September 2022 to March 2024 at a single center, enrolling 95 patients aged 18 to 70 years with a single radiopaque impacted upper ureteral stone. Participants were randomized into two groups: the VC-URSL group used an integrated vacuum suction catheter featuring a stainless steel stabilizing tube and a narrowed distal end to prevent obstruction, while the T-URSL group underwent standard ureteroscopic lithotripsy without vacuum assistance.
