-
Long-term safety of UAS-assisted vs sheathless RIRS in adults with kidney stones
This study tests whether using a ureteral access sheath during the initial RIRS affects long-term safety and outcomes in adults with kidney stones ≤20 mm.
-
Shear wave elastography to distinguish obstructive from pregnancy-related hydronephrosis
We will test whether a painless ultrasound method called shear wave elastography can tell if hydronephrosis in pregnant women with loin pain is due to obstruction or a normal pregnancy change.
-
Using the Sten C1000 system for repairing ureteral strictures
This study is testing a new robotic system to see if it can safely and effectively help people with ureteral strictures get better through surgery.
-
Two thin Percuflex polyurethane stents versus one larger 8Fr silicone stent for malignant ureteral obstruction
The trial will try placing two 6Fr Percuflex polyurethane stents side-by-side versus a single large 8Fr silicone stent in people with malignant ureteral obstruction to see which approach fails less often and how they affect comfort, quality of life, and survival.
-
Using a self-expanding ureteral stent to treat difficult ureteral strictures
This study is testing whether a special stent can help people with tough ureteral strictures feel better and avoid complications over time.
