Summary: A prospective, multi-center, non-randomized trial to demonstrate safety and device performance of the ADVA-Tec Uriprene® Degradable Temporary Ureteral Stent.

Summary: This is a a prospective single-arm pilot study to investigate the safety and feasibility of flexible ureteroscopy under local anaesthesia. All consecutive patients who have undergone kidney-sparing surgery for managing upper tract urothelial carcinoma will be screened for study eligibility. The primary outcome is the procedural technical success rate. Secondary outcomes include the 30-day complica...

Summary: The incidence of kidney stones (urolithiasis) has surged in both developing and developed countries, affecting approximately 15% of the global population. From 2010 to 2019, diagnoses of kidney and ureteral stones rose by 8% in Germany, 26% in France, and 15% in England. Correspondingly, the number of surgical stone removal procedures increased by 3%, 38%, and 18%, respectively. Common treatments ...

Summary: This study, known as the FLAME Trial (Flexible ureteroscopy for Lower pole stones And Mini-pErcutaneous nephrolithotomy), is an international, multicenter, randomized, non-inferiority trial. It aims to compare the effectiveness and safety of flexible ureteroscopy using a flexible and navigable suction ureteral access sheath (FANS) versus mini-percutaneous nephrolithotomy (mini-PCNL) in the treatme...

Summary: This study aims to evaluate whether the use of alpha-blockers before flexible ureterorenolithotripsy facilitates the passage of the ureteral access sheath. The trial will enroll adult patients diagnosed with kidney stones who are scheduled for flexible ureteroscopy. Participants will be randomly assigned to receive or not receive alpha-blockers for seven days before surgery. The primary outcome is...

Summary: The goal of this study is to evaluate the influence of real-time intrarenal pressure measurement availability on surgeons' behavior during ureteroscopy while using the ureteroscope LithoVue Elite.

Summary: This research study is being conducted to assess the ability and efficiency of two laser systems to break up kidney stones during ureteroscopy with laser lithotripsy for kidney stone treatment.

Summary: The purpose of this study is to compare Moses 2.0 pulse modulation technology and the standard high powered Holmium Laser lithotripsy and how it will affect time in the operating room, time using the laser, laser energy, and stone free rates. Currently Moses 2.0 laser technology is FDA approved and currently used in practice since 2021. No study to this date has compared Moses 2.0 without pulse mo...

Summary: The purpose of this study is to determine the differences in stone free results, patient side effects, and patient satisfaction between dusting vs. basket extraction for kidney and ureteral stones (a kidney stone located in the tube between the kidney and bladder) 6 mm and greater in size undergoing ureteroscopic treatment. Dusting is when a laser is used to break a stone down into tiny fragments ...

Summary: Stone disease is a common condition, affecting approximately 9% of Americans in 2007. It causes great morbidity and is also a costly condition, estimated to cost the US healthcare system approximately 3.79 billion dollars in 2007. Ureteroscopy (URS) is the most commonly performed surgical treatment for upper tract stone disease. Ureteral stenting is a common practice after ureteroscopy and placed ...

Summary: The main objective of this study is to evaluate the effectiveness of an auto posturotherapy technique on the RFS at three months of patients treated for lower calyceal urinary stones by extracorporeal lithotripsy (ECL) or retrograde flexible ureteroscopy.

Summary: in this study we are going to evaluate the efficacy of intra-ureteric aminophylline instillation in facilitating ureteric access sheath placement prior to flexible ureteroscopy in reducing ureteric injury rates.
