An ileal conduit is a surgically created pathway that reroutes urine out of the body after the bladder has been removed. Surgeons take a short segment of the small intestine, connect the tubes that carry urine from the kidneys (ureters) to one end, and bring the other end through the abdominal wall to create an opening called a stoma. Urine then drains continuously into a small, flat pouch worn on the outside of the body. It is the most common type of urinary diversion performed worldwide.
Why an Ileal Conduit Is Needed
The most common reason for this surgery is bladder cancer. When cancer has invaded the muscle wall of the bladder, or when earlier treatments like tumor removal and chemotherapy placed directly into the bladder have failed to control the disease, removing the entire bladder (radical cystectomy) becomes the standard treatment. Once the bladder is gone, urine still flows from the kidneys and needs somewhere to go. The ileal conduit provides that new exit route.
Less frequently, an ileal conduit may be recommended for people with severe radiation damage to the bladder, certain birth defects, or neurological conditions that have made the bladder nonfunctional and caused intractable incontinence.
How the Surgery Works
The procedure, sometimes called a Bricker procedure after the surgeon who popularized it, uses a roughly 15 to 20 centimeter piece of the ileum, the lowest section of the small intestine. Surgeons select a segment about 15 centimeters away from where the small intestine meets the large intestine, isolate it from the rest of the bowel, then reconnect the remaining intestine so digestion can continue normally.
The two ureters are then stitched to the closed inner end of this isolated segment. Small temporary tubes called stents are placed inside each ureter to keep them open while the connections heal. The other end of the intestinal segment is brought through the abdominal wall, usually on the right side, and folded slightly outward to create the stoma, a small, round, pink piece of tissue that sits flush with or just above the skin surface. Urine flows from the kidneys, through the ureters, into the conduit, and out through the stoma into an external pouch.
Recovery After Surgery
Most people spend three to seven days in the hospital after the procedure. If the bowel is slow to “wake up” and resume normal function, the stay can extend to two weeks. During the hospital stay, a wound care nurse teaches you how to manage the stoma and pouch system, starting while you’re still in bed and progressing to standing in front of a mirror as you heal.
Deep breathing exercises using a small device called an incentive spirometer are part of recovery for the first week or two, helping prevent lung complications after abdominal surgery. Full physical recovery, including the ability to return to most normal activities, generally takes several weeks, though everyone’s timeline varies depending on their overall health and whether they’re also receiving chemotherapy.
Daily Life with a Urostomy Pouch
The pouch system that attaches over the stoma is flat, waterproof, and worn under clothing. It collects urine continuously since the conduit has no valve or muscle to hold urine back. You empty the pouch when it’s about one-third to one-half full by opening a valve at the bottom, which most people do several times a day. The entire pouching system needs to be changed every three to four days, or immediately if it begins leaking.
Morning is the best time to change the pouch, before drinking any liquids, because urine output is lower. Many people do it standing in the bathroom in front of a mirror. You can also remove the pouch during your daily shower and clean the skin around the stoma at the same time. Urine will continue to trickle from the stoma while the pouch is off, which is normal. Avoid perfumed or oil-based soaps near the stoma, as these can irritate the skin or prevent the pouch from sticking properly.
At night, most people connect the pouch to a larger bedside drainage bag so they can sleep without interruption. Each morning, the night bag is emptied and cleaned with a mixture of one part white vinegar to three parts water, then left to air dry. A smaller leg bag is also an option during the day for situations where emptying the pouch isn’t convenient.
Hydration and Diet
Staying well hydrated is one of the most important things you can do after this surgery. Aim for eight to ten glasses of water (about two liters) each day. Because a section of your intestine has been repurposed, your body absorbs slightly less fluid from food than before, making dehydration a real risk. Dark, amber-colored urine is an early warning sign that you’re not drinking enough.
You may notice mucus in your urine. This is normal. The intestinal lining that forms the conduit naturally produces mucus, and it will continue to do so. Drinking enough water helps keep the mucus thin and prevents it from clogging the pouch. There are no strict food restrictions specific to the conduit itself, but some people find that certain foods change the odor of their urine or cause digestive changes because of the bowel rearrangement.
Possible Complications
Ileal conduits are reliable, but they do carry a meaningful rate of long-term complications, particularly around the stoma. Overall, about 34% of patients experience some type of stoma-related problem. The most common issues include parastomal hernia (a bulge next to the stoma where tissue pushes through the abdominal wall) and stomal retraction, where the stoma sinks below skin level and makes pouching difficult. Stomal stenosis, a narrowing of the opening, occurs in roughly 5 to 15% of patients depending on the population.
Complication rates are notably higher in certain groups. In one study, women who received an ileal conduit for incontinence had a 61% stomal complication rate compared to 18% in other patients, largely due to higher rates of parastomal hernia and stomal retraction.
About 10% of patients develop metabolic problems that need treatment, most commonly a type of acid buildup in the blood called hyperchloremic metabolic acidosis. This happens because the intestinal lining reabsorbs certain chemicals from the urine that the kidneys had already filtered out. Regular blood tests can catch this early. Vitamin B12 deficiency is another concern because B12 is absorbed in the same part of the intestine that was used to build the conduit. Levels should be monitored over time, and supplements may be needed.
Urinary tract infections can also occur, since the conduit provides a shorter, more direct path for bacteria to reach the kidneys. Keeping the pouch clean, staying hydrated, and attending regular follow-up appointments all help reduce this risk.
How It Compares to a Neobladder
The main alternative to an ileal conduit is a neobladder, an internal pouch made from intestine that connects to the urethra so you can urinate somewhat naturally. A large pooled analysis found that neobladder patients reported better urinary function and less urinary bother, which makes sense since they don’t wear an external pouch. However, ileal conduit patients actually scored higher on overall quality of life measures, with a significant difference favoring the conduit on global health status scores. Neobladder patients also tended to report slightly more diarrhea symptoms, though this difference wasn’t statistically significant.
Body image scores were slightly better for neobladder patients, but the difference was small and not statistically meaningful. The choice between the two depends on the extent of the cancer, kidney function, overall health, and personal preference. Not everyone is a candidate for a neobladder, particularly if the cancer involves the urethra or if there are concerns about the ability to self-catheterize when the internal pouch doesn’t empty completely.
Long-Term Outlook
Five-year overall survival rates after radical cystectomy with an ileal conduit range from roughly 38% to 67% across major studies, with the variation largely reflecting differences in cancer stage at the time of surgery. Disease-free survival at five years is around 55%. These numbers reflect the seriousness of the underlying cancer rather than the conduit itself, which functions well for decades in many patients. People who have ileal conduits for non-cancer reasons generally have much longer life expectancies tied to their overall health.
Long-term success depends heavily on consistent follow-up care: monitoring kidney function, checking for metabolic changes, screening for B12 deficiency, and addressing stoma issues early. Most people adapt to their pouch system within a few months and return to work, travel, swimming, and other activities with relatively few limitations.
