Objectives: Although the long-term effects of radiation exposure are not completely predictable, the principle of keeping radiation exposure "as low as reasonably achievable" should be used. The purpose of this study was to compare fluoroscopy times before and after the implementation of a protocol designed to reduce fluoroscopy usage during ureteroscopy.
Methods: A retrospective review was conducted of 300 consecutive ureteroscopy patients at a single institution.
Background And Purpose: Significant bleeding necessitating use of a tamponade balloon, embolization, or renal exploration is a rare but catastrophic complication after percutaneous nephrolithotomy (PCNL). The purpose of this study is to review the success of a novel, minimally invasive technique for controlling percutaneous tract bleeding that is refractory to conventional measures.
Materials And Methods: A retrospective review was performed on four patients with refractory tract hemorrhage that was managed with a novel gelatin matrix hemostatic sandwich technique.
Article Synopsis
- - The study compared a new balloon expandable ureteral access sheath to a conventional one in pigs, focusing on insertion force, flow rate, and urothelial damage.
- - Results showed the novel sheath required significantly less force to insert and had a higher saline flow rate, while also causing less damage to the ureteral lining.
- - The research concludes that the new sheath is a promising alternative for ureteral access, and a clinical trial is underway to further investigate its benefits.
