It has been my experience that the various devices for permanent suprapubic drainage heretofore presented to the profession have been inefficient, cumbersome and uncomfortable.

After considerable experimentation along this line, I have devised an apparatus which is comfortably borne by the patient and which affords excellent drainage.

It is composed of a colostomy pad through the center of which is placed the short arm of a right-angled German-silver tube. This short arm is divided into two parts fitting into each other by a bevel joint. The distal point is fitted with a shoulder for the attachment of a stiff-walled soft rubber tube which is inserted through the suprapubic wound into the bladder. The long arm lies flush with the outside of the colostomy pad and has a shoulder for the attachment of a tube leading to the leg urinal.

Suprapubic drainage apparatus.

The apparatus is comfortable and can be worn
