Retrograde intrarenal surgery (RIRS) is recognized as an effective intervention for renal stones measuring less than 20 mm. This study aims to assess the efficacy and safety of a novel flexible kidney-fixed position compared to the conventional lithotomy position, focusing on lithotripsy efficiency and stone-free rates (SFR). A total of 100 patients undergoing unilateral RIRS between January 2023 and September 2024 were randomly allocated to either the conventional lithotomy position group or the kidney-fixed position group.

- The study aimed to assess the prevalence and risk factors for prostate calcification (PCal) in men aged 40 and older who have benign prostatic enlargement (BPE) during health checkups.
- It analyzed data from 671 men with BPE, finding that 17.3% also had PCal, which was more common in older age groups.
- Key risk factors identified for PCal included increasing age, urine pH levels, and uneven prostatic echoes, indicating a strong correlation between these factors and PCal in BPE patients.
Objective: To find the causes of the failure in the first catheter removal (CR) after transurethral resection of the prostate (TURP) and the related risk factors.
Methods: We collected the clinical data on 285 BPH patients treated by TURP from June 2015 to May 2018. We divided the cases into a successful CR (SCR) and a failed CR (FCR) group and investigated the risk factors for the first CR after TURP by multivariate logistic regression analysis.
