Urinary Tract Anatomy Diagram: Normal vs. Obstructed vs. Infected Conditions #48782 (License: Personal Use)

Panel A shows a healthy urinary system with unobstructed flow from kidneys to bladder. Panel B depicts urethral obstruction causing bladder distension and possible hydronephrosis. Panel C illustrates ascending infection leading to pyelonephritis (K), cystitis (B), and involvement of the trigone (TG) and prostate (PU), with urine (UR) flow impaired.

Used in urology textbooks, patient education materials, and medical websites to explain pathophysiology of urinary obstruction and infections like cystitis or pyelonephritis; matches user intent for visual learning or clinical reference.
