Urinary System FAQs

Common questions about the urinary system

Kidney stones commonly lodge at three narrowings: ureteropelvic junction, crossing of iliac vessels, and ureterovesical junction.

The male urethra (~20cm) passes through the prostate and penis, while the female urethra (~4cm) is shorter, which is why UTIs are more common in females.
