The clinical trial assesses the effect of urinary indwelling time on early continence after robot- assisted radical cystectomy with orthotopic ileal neobladder.

Radical cystectomy is the gold standard for muscle-invasive bladder. Orthotopic ileal neobladder, as one of the urinary diversion methods, is preferred whenever possible to achieve a better postoperative quality of life. After surgery, the patient usually indwells a catheter until the anastomotic site heals. And the urinary indwelling time may have an effect on early continence. This is a prospective study including patients undergoing RARC with orthotopic ileal neobladder. Urinary continence recovery and perioperative complication will be analyzed.

Inclusion Criteria:

1. Patients with pathologically confirmed bladder cancer
2. Undergoing robot-assisted radical cystectomy with orthotopic ileal neobladder
3. Complete perioperative clinical data

Exclusion Criteria:

1. Patients diagnosed with distant metastasis
2. Patients who had urinary incontinence before surgery
3. Patients with unavailable follow-up data

Patients undergoing robot- assisted radical cystectomy with orthotopic ileal neobladder will be enrolled.
