Pediatric Bladder Augmentation — What it is

Enterocystoplasty using ileum, colon, stomach, or dilated ureter to increase bladder capacity and compliance.

Pediatric Bladder Augmentation — Common indications

Small, poorly compliant bladder from congenital disease, fibrosis, neurogenic dysfunction, spina bifida, exstrophy, cerebral palsy, or spinal injury.

Pediatric Bladder Augmentation — Position

Supine.

Pediatric Bladder Augmentation — Surgical access

Lower midline or Pfannenstiel intraperitoneal exposure with bowel harvest, bladder patching, native-bowel reanastomosis, and suprapubic drainage.

Pediatric Bladder Augmentation — Typical duration

Approximately 3.5 h.

Pediatric Bladder Augmentation — Expected blood loss

Approximately 100 mL.

Pediatric Bladder Augmentation — Pain and stimulation

Major open abdominal and bowel-manipulation stimulation requiring substantial multimodal analgesia.

Pediatric Bladder Augmentation — Anesthetic options

GETA with active warming, broad-spectrum antibiotics, epidural or truncal analgesia, careful fluids and electrolytes, and postoperative NG decompression.

Pediatric Bladder Augmentation — Airway

Standard pediatric ETT; consider aspiration risk, neurologic disease, repeated operations, and prolonged intraperitoneal exposure.

Pediatric Bladder Augmentation — IV and blood preparation

At least one reliable IV; add access and blood readiness for dehydration, renal dysfunction, long surgery, or expected hemorrhage.

Pediatric Bladder Augmentation — Monitoring

Standard monitors, temperature, urine output, glucose, and electrolytes; add arterial pressure and serial hematocrit for long or complex cases.

Pediatric Bladder Augmentation — Ventilation and physiology

Controlled ventilation is required; bowel distention and wide abdominal exposure can impair mechanics and increase insensible fluid loss.

Pediatric Bladder Augmentation — Regional options

An indwelling epidural or caudal technique may supplement GA; IV opioids or PCA are alternatives when neuraxial analgesia is unsuitable.

Pediatric Bladder Augmentation — Positioning risks

Pad pressure points and protect the eyes; maintain warming and secure all lines, catheters, and the VP shunt during prolonged supine surgery.

Pediatric Bladder Augmentation — Major intraoperative risks

Bowel injury, hemorrhage, contamination, hypothermia, electrolyte disturbance, latex reaction, VP-shunt infection, and urinary-drainage obstruction.

Pediatric Bladder Augmentation — Major postoperative risks

Electrolyte abnormalities or growth retardation above 50%, bladder calculi 10-50%, rupture 5-10%, bowel obstruction 3%, and bladder cancer 1%.

Pediatric Bladder Augmentation — Postoperative destination

PACU to ward; maintain NG decompression until bowel function returns and antibiotics for at least three days.

Pediatric Bladder Augmentation — Critical communication

Confirm bowel segment, bowel preparation, dehydration, VP-shunt handling, simultaneous stoma or neck procedure, suprapubic tube, and antibiotic duration.

Pediatric Bladder Augmentation — Fast pearl

Augmented-bladder perforation is usually intraperitoneal and bacteriuric, so operative management is generally required.
