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.

Pedal activation in low-light conditions poses the potential for incorrect pedal activation, potentially leading to increased radiation exposure, patient burns, or OR fires. This study compares speed, accuracy, dark adaptation, and surgeon preference for pedal activation in 4 lighting conditions.

- 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.
The purpose of this study was to measure and compare renal pelvic pressure (RPP) between prone and supine percutaneous nephrolithotomy (PCNL) in a benchtop model. Six identical silicone kidney models were placed into anatomically correct prone or supine torsos constructed from patient CT scans in the corresponding positions. A 30-Fr renal access sheath was placed in either the upper, middle, or lower pole calyx for both prone and supine positions.
