Participants in this research study are people who are considering or already receiving therapy using sacral nerve modulation (a treatment that sends electrical impulses to nerves in the lower back). In this research we are measuring brief responses to stimulation that is delivered using this therapy. With our research we are hoping to improve the therapy in the future. We expect that people would be in this research study for only a 20 minutes.

The aim of this study is to investigate whether voclosporin, added to standard treatment, is able to reduce activity of lupus nephritis over a study treatment period of 24 weeks, and to determine its safety as well as the best dose for treatment of lupus nephritis in children or adolescents.

This study is being done to improve outcomes after kidney donation and kidney transplantation. We will test kidney donors and kidney transplant recipients for apolipoprotein L1 gene (called APOL1) variants (or forms of the gene) and to see how these may affect them. Genes control the traits inherited from your family such as your eye color or blood type. Only a blood sample (and possibly urine) will be collected. Information routinely collected as part of surgery will also be used in the study. There will not be any changes to usual medical care.

This research is being to see if a new 3D simulation model is helpful in teaching patients about care of their stomas after surgery. We expect that people will be in this research study for 3-6 months depending on the timing of surgery and postoperative visits. The number of preoperative and postoperative visits, physician exams, scans, X-rays, and laboratory tests for preparation for surgery or after the surgery does not change because of this study.

Nephrotic syndrome is a condition which affects the kidneys causing them to leak protein from the blood into the urine. Nephrotic syndrome is a disease that can improve (remission) and worsen (relapse) at different times throughout childhood. By collecting health information and laboratory samples, our goal is to learn more about these kidney diseases and find better ways to prevent and treat people with nephrotic syndrome. New knowledge will be shared with researchers and the public.

The purpose of this study is to test whether the investigational drug, tegoprubart, in combination with the same standard immunosuppressive medicines (anti-thymocyte globulin, corticosteroids, and mycophenolate) is safe, tolerable and effective compared to tacrolimus. The study will specifically look at the function of the implanted kidney in the tegoprubart group compared to the tacrolimus group and will also assess how well tegoprubart prevents diabetes and prevents rejection.

This research is being done to determine whether not taking oral prophylactic antibiotics after surgery is less effective compared to taking oral prophylactic antibiotics after surgery in preventing urinary tract infections (UTI) within 90 days after surgery. We will divide study participants randomly (similar to tossing a coin) into two groups; one group not receiving postoperative prophylactic antibiotics and the other group receiving prophylactic antibiotics postoperatively. Both groups will receive the exact same preparation before surgery, care during the day of surgery care, postoperative care, and care after hospital discharge.

The Kidney Precision Medicine Project (KPMP) is a research study. Our goal is learn more about kidney injury and kidney disease. By studying your kidneys, we may learn more about why chronic kidney disease happens and how to treat it more effectively or even how to prevent it. Or participants have had diabetes for many years and have not clinical signs of chronic kidney disease. By studying your kidneys, we may learn more about the factors that help protect you from kidney disease. KPMP will last for at least 10 years.

To evaluate the efficacy and safety of iptacopan at a dose of 200 mg twice a day for 52 weeks in patients with atypical hemolytic uremic syndrome (aHUS).

The main purpose of this study is to check how safe the study drug is and how well your body handles taking it. We will also check if the study drug works to improve your kidney function, if has an impact on your daily life and the amount of the study drug in your blood over a period of time (called pharmacokinetics)

The purpose of CureGN2 is to gather a group of people with glomerular disease to create a source of information and blood and urine samples, so that researchers can easily and effectively study glomerular disease.

Currently, there are no approved treatment options for pediatric subjects with proteinuric kidney conditions. The study will look at the safety, efficacy, and pharmacokinetic (PK) trial in children ≥1 to <18 years treated for up to 108 weeks with the drug sparsentan.

People with Primary MN lose more protein in their urine because the filters in their kidneys may be damaged. It is possible that some belimumab may also be lost in the urine because of this. This study will measure belimumab in the blood to decide if people with high urine protein should receive a higher dose of belimumab. Another purpose of this study is to help learn about whether the combination of belimumab and rituximab treatment is effective in making and keeping Primary MN inactive.

The purpose of this study is to capture clinical information on how kidney disease affects the health of women, focusing on menstrual and reproductive health, the transition to menopause (the time when your menstrual periods stop permanently), and menopause itself. We also wish to learn more about how women’s health affects their kidney disease, bone and heart health.

The current study is designed to determine which strategy (regular screening or screening only in the presence of symptoms) is more effective in preventing heart attacks in kidney transplant candidates. Another goal of the study is to determine whether biomarker tests are able to predict the need for regular CAD screening tests.

The goal of this study is to understand how urine and bladder tissue changes from infection, or a bladder that does not function normally, in people who use a catheter to empty their bladder. This may help future people because it can help determine who needs antibiotics to treat an infection in the bladder, and will help avoid the cost and side effects of using antibiotics in people who do not have a true infection. This study will take less than 1 hour – the time required to provide a urine sample in clinic. Or, if a participant is undergoing bladder Botox injection, the time necessary to participate in the study will add approximately 5 minutes to the total surgery time.

This study focuses on testing new treatments on prostate tissue that has been removed during surgery. All testing is done in a lab setting to help develop and improve potential treatment options.

The purpose of the research is to find out if atrasentan delays worsening of kidney function in IgAN, FSGS, and Alport Syndrome.

The effect of enzyme replacement therapy on how well your kidneys are responding to enzyme replacement therapy (ERT) is not clear from blood and urine tests alone, but may be more clear in comparisons of kidney biopsies performed before and some time after ERT has been initiated, and this is what we are focusing our study efforts on. The purpose of this study is to obtain your permission to allow us to study the kidney biopsy tissues (collected for medical reasons) after the regular routine studies have been completed. Through our special research measurements and additional study, we hope to be able to see and measure very specific changes in the kidney tissues from Fabry patients taking ERT. We also hope that through these studies of what happens within the kidney before and after starting ERT, we are able to reveal valuable information about the importance of factors like your age that you started ERT, the amount or dosage of ERT, and any differences seen between males and females.
