Male Bladder

Description

A 3D model of the male urinary bladder showing the external shape, detrusor muscle wall, and internal trigone. The two ureteral orifices and the internal urethral orifice mark the trigone's corners. The bladder neck transitions into the prostatic urethra, passing through the prostate gland. The male bladder sits superior to the prostate, and the vas deferens cross the ureters on the posterior surface. The relationship between the bladder neck and prostate is clinically relevant for benign prostatic hyperplasia, where prostate growth compresses the urethra and obstructs outflow. Bladder anatomy is a focus in urology and male pelvic surgery. The model suits patient education and surgical anatomy teaching. Reviewed by a medical advisory board. Clean geometry for rendering, real-time, and 3D printing.
