Objectives: To comprehensively review the literature on paratesticular tumors and to develop a new management algorithm.
Methods: A systematic review was conducted from 1980 to 2024 in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A search was performed on PUBMED to identify studies investigating paratesticular tumors, limited to cases >16 years of age.
Objectives: To determine whether serial 24-hour urine collections from the same patient over time result in improved stone risk parameters.
Patients And Methods: Using a 24-hour urinalysis database, 1832 tests from 688 patients collected over a 10-year period were retrospectively reviewed. Patients included in the analysis had a minimum follow-up of 2 years and at least three 24-hour urine collections.
Introduction: Novel Direct-In-Scope-Suction ureteroscopes (DISS-U) have recently been introduced to facilitate removal of small stone fragments. The purpose of this study was to compare two novel DISS-U to a conventional ureteroscope to determine efficiency for suctioning fluid and stone dust at different deflection angles.
Methods: Three disposable ureteroscopes were evaluated, including two DISS-U with 5.
Purpose: Current occupational recommendations limit fetal radiation dose to 1 mSv. With increased gender diversity in urology, understanding radiation exposure during pregnancy is crucial. The purpose of this study was to determine surgeon uterine radiation dose during percutaneous nephrolithotomy (PCNL) and compare effectiveness of several radiation reduction strategies in a cadaver model.

- The thulium fiber laser (TFL) can improve lower-pole lithotripsy by using small fiber diameters for focused beam delivery, making procedures potentially more efficient.
- A study compared the performance of 150 µm and 200 µm TFLs in a kidney model, finding that the 150 µm fiber required less time and energy to perform lithotripsy on calcium oxalate stones.
- The results indicated that using the 150 µm fiber at 0.2 J and 100 Hz provided the fastest lasing and procedure times, highlighting the advantages of smaller fibers for better outcomes in laser lithotripsy.

Objective: To investigate the impact of renal function on the risk, severity, and management of radiation cystitis in patients who underwent postoperative radiation therapy for prostate cancer.
Methods: Retrospective data was assessed from patients treated with adjuvant/salvage radiation therapy at a single academic institution between 2006 and 2020. The incidence, severity, and management of radiation cystitis were compared between three groups: CKD 0-2, CKD 3-4, and CKD 5.
