By the tenth day he was passing urine from the urethra, and on the twenty-fifth day there was a complete cicatrix of the parts; fifteen days later he suffered from an attack of retention of urine lasting five days; this was completely relieved after the expulsion of a small piece of trouser-cloth which had been pushed into the bladder at the time of the accident.

Post reports the case of a young man who, in jumping over a broomstick, was impaled upon it, the stick entering the anus without causing any external wound, and penetrating the bladder, thus allowing the escape of urine through the anus.

Couper reports a fatal case of stab-wound of the buttocks, in which the knife passed through the lesser sacrosciatic notch and entered the bladder close to the trigone.

The patient was a man of twenty-three, a seaman, and in a quarrel had been stabbed in the buttocks with a long sailor's knife, with resultant symptoms of peritonitis which proved fatal.

At the autopsy it was found that the knife had passed through the gluteal muscles and divided part of the great sacrosciatic ligament.
