12 Clinical Trials for Various Conditions
This is a single arm, interventional pilot study of using chlorhexidine irrigation intra-operatively and post-operatively among patients undergoing radical cystectomy with urinary diversion. The intervention comprises of using irrigation of ileal conduit or ileal neobladder intra-operatively and then for irrigation of either post-surgery with Irrisept ®. The sterilization of urine will be assessed at 10 days after cystectomy. Incidence of symptomatic urinary tract infections within the 30-day post-operative period will be estimated.
This proposal will aim to improve the understanding about the treatment decision in the type of urinary diversion and identify patient knowledge gaps about uncertainty around patient decision-making.
Ureteroenteric anastomotic stricture is a well-known complication of urinary diversion which occurs in 4-25% of patients. Recent study has yielded that radiation is a significant risk factor for development of ureteroenteric stricture. The goal of this study is to determine whether intraoperative use of SPY fluorescent angiography during urinary diversion reduces rate of ureteroenteric stricture. This study will include 215 patients who have undergone urinary diversion over the past 5 years as historic controls and compare ureteroenteric stricture rates to a prospective cohort of patients in whom intraoperative SPY fluorescent angiography was used at the time of urinary diversion to assess the anastomotic perfusion. This will include injection of ICG intravenously as well as utilization of the SPY device to assess ureteral perfusion before and after ureteroenteric anastomosis. Based on power analysis, this study will require approximately 50 patients in our prospective group to detect a clinically significant difference of 5% between groups. Data analysis plan includes the use of chi square test for comparison of stricture rates between groups. Clinical outcomes will be followed prospectively, with no amendment to standard follow-up per physician.
Intracorporeal urinary diversion (ICD) provides superior postoperative outcomes compared to extracorporeal urinary diversion (ECD). The investigators' hypothesis that ICD may provide clinical benefit is based on principles of less bowel and ureteral handling, superior operating room workflow, less exposure to the external environment, and optimal visualization with ICD while utilizing a smaller incision compared to ECD. ICD should have less bowel-related complications, lower pain scores allowing patients to be discharged from the hospital sooner and regain functional independence more quickly.
The purpose of this study is to see if the Neo-Urinary Conduit(NUC), which is made in the laboratory from a combination of a patient's own cells and other materials can be used to form a conduit to safety allow urine flow from the kidneys to outside the body after radical cystectomy in patients with bladder cancer.
This is a prospective, randomized study of two types of continent ileal neobladder construction in patients undergoing cystectomy for primary bladder cancer. Patients will be randomly assigned to have either a T-pouch or a Studer pouch constructed at the time of their surgery. They will be followed long-term to determine the relative advantages and disadvantages of the two types of diversion. The investigators' hypothesis is that the inclusion of an antireflux mechanism in the T-pouch will result in significantly fewer episodes of symptomatic urinary tract infection, and will have a lower incidence of upper tract dilation and loss of renal function over the long term.
Prospective multicenter observational study of early infancy ureteral reimplantation for distal ureteral obstruction. The study is an observation study since the investigators will not assign specific interventions to the subjects of the study. The purpose of the study is to describe the surgical outcomes of early infancy ureteral reimplantation. Infants under 6 months of age with unilateral obstructed distal ureter, no other urologic pathologic and a normal contralateral kidney who have been recommended a ureteral reimplant by their pediatric urologist are eligible for the study. Patients that consent for the study will be prospectively followed for 1 year to record the outcomes of the surgery.
There is a pressing need to develop a personalized, value-based decisional tool for bladder cancer patients undergoing radical cystectomy (bladder removal) and urinary diversion to help them with communication with the physicians, shared decision making, and preparation for disease-management and follow-up care. The proposed intervention, the Personal Patient Profile - Bladder Cancer (P3-BC), will be the first intervention to address these issues. Results of this pilot randomized feasibility study will provide evidence of the feasibility and acceptability of the P3-BC and will guide further refinement of the tool for a larger experimental trial, with potential dissemination of the program via the Internet and hand-held computing devices.
For patients with certain types of bladder cancer, the removal of the bladder and the construction of an artificial bladder or reservoir are the only treatment options. Both before and after treatment, patients and caregivers face profound challenges preparing for surgery and planning for tasks during their recovery. To aid in recovery and enhance quality of life this program of research will develop and evaluate a multi-stage intervention geared towards patients and their caregivers. Part 1 of this program will have a nurse or trained health professional prepare both patients and their caregivers before treatment about the upcoming surgery. During this time the nurse will also demonstrate the necessary tools and techniques for stoma care. In addition, patients and their caregivers will receive access to a recovery website, specifically designed for bladder cancer patients to be used as a resource for after treatment. The website will be part 2 of this research and will contain important recovery information, videos about post-surgical care, testimonials by other patients and physicians and a variety of other resources. Patients and caregivers in the control group will receive the Facing Forward brochures from the National Cancer Institute in part 2. This research has been funded by the National Cancer Institute and will be the first study to address the needs of bladder cancer patients and their caregivers. The ultimate goal of the study is to reduce infections and unplanned nurse/ER visits and improve quality of life for both patients and their caregivers. This new program will be evaluated over the course of 12-months and if found successful, has the potential to be disseminated throughout the health care systems of the two study sites.
To provide patients with bladder cancer who are scheduled to undergo radical cystectomy with a preoperative high-arginine nutritional supplement. The investigator will measure patient adherence to the regimen, tolerability of the supplement and feasibility of supplementation. Secondary outcome measures will include differences in length of stay and complication rate between groups.
The current study is designed to assess the impact of an enriched oral nutritional shake (Ensure Plus®) to improve the nutritional status and patient outcome after surgery to remove a cancerous bladder (radical cystectomy). Radical cystectomy with urinary diversion using a segment of intestine is the standard of care for invasive bladder cancer. This operation has a high complication rate and several studies have shown that this may be directly related to poor nutrition. The investigators believe that patients who consume an enriched nutritional shake before and after surgery will improve their nutrition status and experience fewer complications, shorter length of stay and less readmissions compared to those who do not. Patients who are scheduled to undergo elective radical cystectomy will be eligible for enrollment. Once enrolled, they will be randomly assigned to one of two groups. One group will be offered Ensure Plus® twice daily for 2 weeks before and 4 weeks after their surgery and the other will be offered a daily over-the-counter multivitamin for the same period of time. The investigators will follow both groups for up to 30 days after their surgery and compare clinical outcomes such as: complication rates, length of stay, readmission rates and mortality as well as measure serum markers of nutrition status and assess changes in body composition.
The goal of this clinical research study is to evaluate how many lymph nodes are left behind after robotic-assisted removal and are then found after a wider incision is made, in patients who are having their bladder removed for the treatment of bladder cancer. The primary objective is to compare the lymph node yield achieved by performing a robotic-assisted laparoscopic extended pelvic lymph node dissection (RA-PLND) compared to a second-look open lymph node dissection (O-PLND) among patients undergoing radical cystectomy for transitional cell carcinoma of the bladder. The secondary objectives will be to collect prospective outcomes data related to the performance of RA-PLND and robotic-assisted cystectomy (RA-C) including operative times, estimated blood loss, transfusions, complications, return to diet, utilization of pain medication, hospital length, return to regular activities.
