Stoma bags — also called ostomy bags, colostomy bags, ileostomy bags or urostomy bags — are pouches worn over a stoma to collect output after ostomy surgery. EMIS+ supplies genuine stoma bags in Singapore from trusted brands including Coloplast and ConvaTec, in one-piece and two-piece systems, for colostomy, ileostomy and urostomy needs.
How to choose the right stoma bag
-
By stoma type: Colostomy bags (usually closed or drainable, for firmer output), ileostomy bags (drainable, for liquid/frequent output), and urostomy bags (with a tap/valve for urine).
-
One-piece vs two-piece: One-piece has the baseplate and pouch joined (simpler, more flexible); two-piece lets you change the pouch while leaving the baseplate on the skin (gentler on peristomal skin).
-
Closed vs drainable: Closed pouches are removed and replaced; drainable pouches are emptied and reused through the day.
-
Cut-to-fit vs pre-cut: Cut-to-fit baseplates are trimmed to match an irregular or changing stoma; pre-cut suits a settled, round stoma.
Common questions
What is the difference between a colostomy bag and a stoma bag? "Stoma bag" is the general term; a "colostomy bag" is a stoma bag used for a colostomy specifically. Ileostomy and urostomy bags are the other two types.
How often should a stoma bag be changed? This varies by system and output — many closed pouches are changed 1–3 times daily, while drainable pouches and two-piece baseplates are typically changed every 1–3 days. Follow your stoma nurse's guidance.
Are these suitable after recent surgery? A new or swollen stoma changes size in the early weeks, so cut-to-fit or a measuring guide is often recommended. When in doubt, check with your stoma care nurse.
