Urine test for overactive bladder markers
This study looks at whether certain substances in your urine (called neurotrophins) can help doctors better understand overactive bladder (OAB). You will give a urine sample and answer some questions to help researchers find a simple, noninvasive way to confirm OAB.

Fullerton, CaliforniaAges 18–89 - NCT06470685Enrolling by invitation
Preventive prostate removal for prostate cancer risk
This study tests whether removing the prostate before cancer develops can help people at higher risk, such as those with certain gene changes (like BRCA2), a strong family history, or Black African/Caribbean ancestry. It also includes people who have already had their prostate removed for cancer treatment.
LondonAges 18 years+ - NCT06463964Enrolling by invitation
Predicting kidney injury in emergency heart failure patients
This study looks at what factors might predict acute kidney injury (sudden kidney damage) in people who come to the emergency room with acute decompensated heart failure (a sudden worsening of heart failure). The goal is to help doctors identify who is at highest risk so they can take steps to protect the kidneys.

ECHO diabetes and chronic conditions training for care teams
This trial tests a program (ECHO) to help healthcare teams at busy clinics better support patients with diabetes and other ongoing health conditions. It focuses on training staff, not on giving you a new treatment.
Santa Fe, New MexicoAges 18–89 - NCT06447038Enrolling by invitation
Early detection of chronic kidney disease study
This study is looking for ways to find chronic kidney disease early, before it gets worse. It may help people who are at risk or have early signs of kidney problems.
BurgosAges 18 years+ - NCT06437899Enrolling by invitation
Numbing methods for Botox in the bladder for overactive bladder
This study compares two ways to numb the bladder before a Botox injection for overactive bladder: local anesthesia (numbing medicine in the bladder) versus sedoanalgesia (medication to relax and reduce pain). The goal is to see which method works better and makes patients more comfortable.
