This trial tests whether repeatedly adding sterile fluid into the womb can help fetuses with severe kidney failure grow enough lungs to survive after birth. Pregnant women with early pregnancy kidney failure can choose to receive the infusions or just be monitored. Babies who sur…

This study tested a special stent called MEMOKATH 051 in 13 adults with long-term ureter blockages who usually need a standard double J stent. The goal was to see how long the new stent lasts and how well it is tolerated over 3 years. Participants had the new stent placed during …

This study tested whether a special ultrasound with a contrast dye (Definity) can detect kidney obstructions. Ten adults with a blocked kidney had ultrasound scans before and after surgery to relieve the blockage. The goal was to see if this method works as well as standard nucle…

This study tested whether barbed sutures (V-Loc) are safer and easier to use than standard polyglactin sutures (Vicryl) in minimally invasive kidney surgery for a blocked ureter. Forty adults aged 18 to 60 were randomly assigned to receive either barbed or standard sutures during…

This study tested a special ureteral stent with a magnetic end in 67 children with urinary tract problems or kidney transplants. The goal was to see if the stent could be removed without general anesthesia, using a magnetic catheter instead. The approach aims to make the removal …

This study looked at whether giving antibiotics before a kidney drainage procedure (called percutaneous nephrostomy) prevents urinary tract infections in cancer patients whose urinary tract is blocked by a tumor. Researchers reviewed records of 320 cancer patients who had the pro…

This completed registry followed 379 people who received a Boston Scientific ureteral stent to treat a blocked ureter. The goal was to see how well the stent worked and if it caused any serious side effects. Patients also reported on their quality of life. The study provides real…

This study looked at 21 pregnant women and their babies to understand how surgery before birth changes the immune system. The goal was to find out if immune system activation might cause early labor. Researchers collected blood samples and studied the placenta to track immune cha…
