Urostomy: Selecting Your Pouch

After a urostomy, urine drains into a disposable pouch. The pouch sticks to the skin around the stoma. An adhesive skin barrier holds the pouch in place. This barrier also protects the skin and prevents leakage. Most pouches are made of lightweight, odorproof plastic and lie flat against the body.

Types of Pouches

There are many styles of pouches. Your WOC nurse or other healthcare provider will help you select the one that's best for you. The skin barrier has to fit around the stoma without touching it. The barrier must stick well to prevent leakage or odor from the pouch.

One-Piece Drainable Pouch

  • The skin barrier and pouch come as one piece. The skin barrier holds the pouch onto the skin.

  • Urine is emptied from the bottom of the pouch through a drain. The drain can be opened and tightly closed. Drain styles differ, depending on the pouch selected.

Two-Piece Drainable Pouch

  • The skin barrier and pouch are separate pieces. The skin barrier is applied to the skin. The pouch snaps onto the skin barrier.

  • Urine is emptied from the bottom of the pouch through a drain. The drain can be opened and tightly closed. Drain styles differ, depending on the pouch selected.

Sizing the Stoma Opening

For the pouch to fit around the stoma, the opening of the skin barrier must be the right size. Some openings are precut, and others must be measured and cut. To find the correct size for your stoma, use a measuring guide. Most pouches come with a guide in the box. Your healthcare provider may also give you one.

  • Find the smallest hole on the guide that fits around the stoma without touching it. There should be about 1/8" between the stoma and the hole on the guide.

  • To cut the opening yourself, center the guide hole on the back of the skin barrier. Trace the pattern. Then cut the opening using curved scissors.

  • For precut openings, order pouches with the sized openings that match the size of the hole on the measuring guide.

Pouch Accessories

You can buy other stoma care products through special catalogs, at medical supply stores, on the Internet, and at some drugstores.

  • Powders and wipes add an extra layer of skin barrier. They also help protect irritated skin.

  • Stoma paste and skin barrier wafers fill in uneven places in the skin around the stoma. This helps the pouch stick better.

  • Convex skin barriers help make a better seal. They are used if the skin around the stoma is uneven or the stoma is level with or sinks below the skin. Some convex barriers come with a pouch attached. Others are inserts that can be added to any pouch.

  • Pouch filters and deodorants help prevent odor.

  • Ostomy belts help keep the pouch in place.

  • Pouch covers help keep the skin under the pouch dry and comfortable.

  • A night drainage system lets you sleep all night without emptying your pouch. This system can also help prevent urine from pooling around the stoma, which leads to infection.
