Urinary Bladder

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...

Summary

This study presents a novel bladder flap technique for severe bladder neck contracture (BNC). The "falling-down" flap provides durable tissue for reconstruction, offering a potential alternative to traditional methods.

Area of Science:

Urology
Surgical Innovation

Background:

Recalcitrant bladder neck contracture (BNC) presents a significant clinical challenge.
Traditional reconstructive techniques for BNC may have limitations in complex cases.
