Insights

Long-term ileal neobladder use in patients reduces intestinal mucosa cells and microvilli, impacting urinary resorption. Mucus secretion remains stable, indicating tissue adaptation after bladder substitution.

Area of Science:

  • Urology
  • Gastroenterology
  • Cell Biology

Context:

  • Investigating long-term effects of ileal neobladder surgery on intestinal mucosa.
  • Assessing ultrastructural changes in ileal tissue post-bladder substitution.

Purpose:

  • To evaluate the ultrastructural changes in the ileal mucosa of patients with ileal neobladders.
  • To correlate observed cellular changes with functional outcomes like urinary resorption and mucus secretion.

Summary:

  • Electron microscopy revealed significant reductions in normal intestinal mucosa cells, mitochondrial density, and microvilli in ileal neobladder biopsies.
  • Goblet cell density remained comparable to normal ileal tissue, suggesting preserved mucus secretion.
  • These findings support clinical observations of decreased urinary resorption over time.

Impact:

  • Provides detailed ultrastructural evidence for functional changes in ileal neobladders.
  • Contributes to understanding the long-term adaptation and potential complications of ileal neobladder surgery.
  • Informs clinical management and patient counseling regarding expectations after bladder substitution.

Urinary Bladder01:23

Urinary Bladder

The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...

Anatomy of the Genitourinary System II: Bladder and Urethra

The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...

Imaging Studies VI: Voiding Cystourethrography and Cystography

Voiding Cystourethrography (VCUG) and Cystography are specialized radiographic procedures used to examine the structure and function of the bladder and urethra.Voiding Cystourethrography (VCUG)A Voiding Cystourethrogram (VCUG) is a diagnostic imaging procedure that assesses the anatomy and function of the lower urinary tract. It focuses on the bladder, bladder neck, and urethra, helping detect abnormalities such as vesicoureteral reflux (VUR)—the backward or reverse flow of urine into the...
