About this study

Official title: A Prospective Multicenter Randomized Controlled Clinical Trial of Extraperitonealization for Prevention of Parastomal Hernia After Ileal Conduit

Many complications may occur after ileal conduit, with the incidence increasing with time after surgery. Nearly half of the complications are related to stoma and ureteroileal anastomosis. The investigators believe that the surgical technique is responsible for these complications, and therefore have devised a modified technique for creating the ileal conduit that should help prevent these complications after surgery. The investigators' retrospective study shows that modified surgical technique for ileal conduit urinary diversion appears to be effective for reducing early and late complications related to the stoma. Thus the investigators would like to perform a prospective multicenter randomized controlled clinical study to prove the investigators' results.

The investigators plan to enroll 104 patients, and randomizedly divide the participants into two groups, with one group 52 patients undergoing conventional ileal conduit, another group 52 patients undergoing modified ileal conduit.

Read the detailed description

The ileal conduit (Bricker) has been used for urinary diversion for more than half a century. Widely accepted to be a simple and safe form of urinary diversion, it remains one of the most commonly used techniques for urinary diversion after radical cystectomy for bladder cancer. However, many complications may occur after ileal conduit, with the incidence increasing with time after surgery. Interestingly, nearly half of the complications are related to stoma and ureteroileal anastomosis. Among the complications, parastomal hernia is the most common. Female gender, low preoperative serum albumin level, high BMI or severe obesity, and prior laparotomy have been shown to be risk factors for parastomal hernia. But the mechanisms by which these variables lead to stoma related complications have not yet been fully elucidated. The investigators believe that the surgical technique is responsible for these complications, and therefore have devised a modified technique for creating the ileal conduit that should help prevent these complications after surgery. The investigators' retrospective study shows that modified surgical technique for ileal conduit urinary diversion appears to be effective for reducing early and late complications related to the stoma. Thus the investigators would like to perform a prospective multicenter randomized controlled clinical study to prove the investigators' results.

The investigators plan to enroll 104 patients, and randomizedly divide the participants into two groups, with one group 52 patients undergoing conventional ileal conduit, another group 52 patients undergoing modified ileal conduit.

Questions about this trial

What is this clinical trial studying?

A study testing Modified ileal conduit in people with Bladder Cancer, run by Sun Yat-sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Incidence of parastomal hernia in 2 years (time frame: 2 years). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2024.
