This study reports on a novel laparoendoscopic single-site subtotal cystectomy and augmentation enterocystoplasty for neurogenic bladder. The minimally invasive technique through a single port showed encouraging initial results with no complications.

Area of Science:

Urology
Minimally Invasive Surgery
Surgical Techniques

Background:

Neurogenic bladder, often resulting from conditions like congenital sacral lipoma, can cause significant urinary dysfunction.
Traditional treatments may involve open surgery, carrying higher morbidity.
Advancements in minimally invasive techniques offer potential for improved patient outcomes.

Observation:

A 20-year-old female with neurogenic bladder underwent laparoendoscopic, single-site, subtotal cystectomy and augmentation enterocystoplasty.
The procedure utilized a novel multichannel transumbilical port, a 5-mm video laparoscope, SonoSurge, and flexible scissors.
Approximately 70% of the bladder was resected, with extracorporeal ileal pouch reconstruction and laparoscopic anastomosis.

Findings:

The surgery was completed in 300 minutes with minimal blood loss (<100 mL).

There were no intraoperative or postoperative complications, and the hospital stay was 6 days.

Postoperative imaging confirmed a watertight anastomosis and increased bladder capacity, with successful intermittent self-catheterization for bladder emptying.

Implications:

Laparoendoscopic single-site surgery through a single port is a feasible and encouraging approach for complex bladder reconstruction.
The use of a larger diameter port facilitates extracorporeal bowel reconstruction in minimally invasive procedures.
This technique holds promise for various complex urological reconstructions, potentially reducing invasiveness and improving recovery.
