Robotic Neobladder

A robotic neobladder is a type of urinary diversion performed after bladder removal (radical cystectomy) where surgeons use the robotic approach to create a new bladder (neobladder) from a segment of the patient’s intestine. This allows urine to pass through the urethra in a way that closely mimics natural urination.

What It Is

  • After the bladder is removed (due to bladder cancer or other severe disease), the surgeon uses a section of the ileum (small intestine) to construct a spherical “new bladder.”
  • Using robotic surgery, the neobladder is shaped inside the body (intracorporeal) and attached to the ureters (bringing urine from kidneys) and the urethra (to allow voiding).

Advantages of Robotic Neobladder

  • Minimally invasive: Smaller incisions, less blood loss, quicker recovery vs open surgery.
  • Natural voiding: Patient can pass urine through the urethra instead of needing a stoma bag.
  • Cosmetic benefit: No external bag (compared to ileal conduit).
  • Quality of life: Many patients prefer it because it feels more natural.

Recovery & Lifestyle

  • Hospital stay: ~7–12 days.
  • Catheter: Usually required for 2–3 weeks while the neobladder heals.
  • Training period: Patients must learn how to contract abdominal muscles and relax pelvic muscles to void.
  • Continence outcomes:
  1. Daytime continence: achieved in ~80–90% of patients after 6–12 months.
  2. Nighttime continence: usually lower (~70%).

Who Is a Candidate?

  • Patients with good kidney function.
  • No urethral cancer involvement.
  • Motivated, younger or healthier patients who can handle the training.
  • Not ideal for very frail patients or those with poor bowel/kidney function.

A robotic neobladder is the most advanced urinary diversion option after robotic cystectomy. It restores near-normal urination, but requires patient motivation, rehabilitation, and close follow-up.
