About this study
To compare the perioperative, functional, and oncologic outcomes between non nerve sparing and nerve sparing robot-assisted radical cystectomy with orthotopic ileal neobladder in male patients with bladder cancer.
Read the detailed description
This study will enroll male patients with bladder cancer who will undergo robot-assisted radical cystectomy with orthotopic ileal neobladder. The patients will be distributed into two comparable groups according to surgical procedures: non nerve sparing group and nerve sparing group. Patient demographic and pathologic, perioperative, functional, and oncologic outcomes will be compared between the two groups.
- Conditions
- Bladder Cancer
- Being tested
- nerve sparing
- Medical subject headings
- Urinary Bladder Neoplasms
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
nerve sparingProcedure or surgery
When resect the bladder and prostate, the neurovascular bundles around the prostate will be preserved.
| Study group | Role | What they receive |
|---|---|---|
| nerve sparing group | Patients will be preverved the neurovascular bundles during the resection of bladder and prostate of the operation. Receives: Procedure: nerve sparing | |
| non nerve sparing group | Patients will receive standard radical cystectomy (not preserve the neurovascular bundles) during the operation. |
What is being measured
The primary outcome is the main question the study is designed to answer.
day-time continence rate
Patients were considered continent when they required 0 or 1 safety pad during the day-time.
Measured: 6 months
night-time continence rate
Patients were considered continent when they required 0 or 1 safety pad during the night.
Measured: 6 months
postoperative sexual function
The sexual function are evaluated by the International Index of Erectile Function-5 (IIEF-5).
Measured: 6 months
Secondary outcomes (5)
perioperative complication rate
Measured: 3 months
operative time
Measured: 24 hours
estimated blood loss
Measured: 24 hours

What does the primary outcome measure?
day-time continence rate (time frame: 6 months). The study lists 3 primary outcomes in all. 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?
