Ultrasound Video showing Stones in Prostatic urethra.

This video shows Stones in Prostatic urethra. The urethra runs through the center of the prostate, from the bladder to the penis, letting urine flow out of the body. The prostate secretes fluid that nourishes and protects sperm. During ejaculation, the prostate squeezes this fluid into the urethra, and it's expelled with sperm as semen. The prostatic urethra is the portion of the urethra that traverses the prostate. It originates in the region of the bladder neck, courses roughly 2.5 cm inferiorly, and terminates at the membranous urethra. Urethral calculi are preponderantly found in the prostatic urethra just proximal to the narrow membranous portion. These are either formed in the prostatic urethra or migrated from the upper urinary tract. They are usually small, but numerous cases of giant stones have been reported. Primary urethral (native) calculus is a rare form of urolithiasis and often associated with urethral diverticulum, stricture, or previous surgery. Secondary (migrating) calculi often originate from kidney or bladder and were reported to be at least 10 times more common in occurrence than the primary stones. Urethral Calculus.
