Congenital phimosis is said to be very common among the natives of Solomon Islands.
In September, 1695, Bernard removed two stones from the meatus urinarius of a man, after a lodgment of twenty years.

Block mentions a similar case, in which the lodgment had lasted twenty-eight years.
Walton speaks of a urethral calculus gradually increasing in size for fifty years.

Ashburn shows what he considers the largest calculus ever removed from the urethra.

It was 2 1/8 inches long, and 1 1/4 inches in diameter; it was white on the outside, very hard, and was shaped and looked much like a potato.

Its dry weight was 660 grains.
