After your bladder is removed, urine still flows from your kidneys, but it needs a new exit route. Surgeons create that route during the same operation, using a section of your intestine to either channel urine outside your body or build an internal replacement. There are three main options, and which one you get depends on your overall health, your anatomy, and your preference.
The Three Main Options
Every approach to rerouting urine after bladder removal is called a urinary diversion. The three types differ in one fundamental way: how much they resemble normal urination.
An ileal conduit (urostomy) is the most common and simplest option. A surgeon takes a short segment of your small intestine, connects your ureters to one end, and brings the other end through your abdominal wall as a small opening called a stoma. Urine drains continuously into an external pouch you wear on your skin. You don’t control the flow at all.
An Indiana pouch (continent cutaneous diversion) also uses intestinal tissue, but the surgeon shapes it into an internal reservoir. A narrow channel connects the reservoir to a small stoma, often at or near your belly button. Urine collects inside the pouch, and you drain it several times a day by sliding a thin catheter into the stoma. Between catheterizations, nothing drains on its own, so there’s no external bag.
An orthotopic neobladder comes closest to the original setup. The surgeon fashions a pouch from small intestine and connects it directly to your urethra, in the same position your bladder once sat. Urine travels from your kidneys through your ureters into this new pouch, then out through the urethra when you’re ready. You urinate sitting on a toilet, but the technique is different from what you’re used to.
Living With an Ileal Conduit
Because the conduit has no valve or sphincter, urine flows out of your stoma around the clock. A flat, adhesive pouching system sticks to the skin around the stoma and collects the urine. You empty the pouch through a spout at the bottom whenever it gets about one-third full, which typically means every few hours during the day. The entire pouching system needs to be changed one to two times per week.
At night, you can attach a bedside drainage bag to the pouch so urine flows by gravity while you sleep, reducing the need to wake up and empty it. The stoma itself is painless (intestinal tissue has no nerve endings for sharp sensation), but the surrounding skin needs consistent care to prevent irritation from urine contact. Most people develop a quick routine within the first few weeks and find the maintenance straightforward.
Living With an Indiana Pouch
The Indiana pouch gives you a flatter profile under clothing since there’s no external bag. The tradeoff is that you need to catheterize yourself on a schedule. You insert a small, flexible catheter through the stoma valve, let the pouch drain completely, then remove the catheter. The whole process takes a few minutes and happens multiple times a day.
Sticking to a regular schedule matters. If you let the pouch overfill, it stretches and can eventually weaken the valve mechanism. Over time, the pouch’s capacity increases slightly as the intestinal tissue adapts, which can space out catheterizations a bit. Most people carry a small kit with catheters and supplies so they can drain the pouch away from home without difficulty.
Living With a Neobladder
A neobladder is the only option that lets you urinate through your urethra without an external device. But it doesn’t work like a natural bladder. Intestinal tissue can’t contract on command the way bladder muscle does, so you empty the neobladder by bearing down with your abdominal muscles while simultaneously relaxing your pelvic floor.
The technique takes practice. Memorial Sloan Kettering Cancer Center advises sitting all the way back on the toilet seat with your feet flat on the floor, even if you have a penis, because sitting helps relax the pelvic floor. You breathe in through your nose and out through your mouth, gently directing pressure downward toward the neobladder. Some people find that whistling or hissing through their teeth helps create enough abdominal pressure to start the flow. Straining or rushing doesn’t help and can actually make it harder.
Because the intestinal pouch has no built-in stretch receptors like a natural bladder, you won’t feel the usual “I need to go” urge. Instead, you learn to urinate on a timed schedule, typically every three to four hours during the day. Some people describe a vague sense of fullness or pressure once they get familiar with their neobladder, but the signal is much subtler than what a natural bladder provides.
Continence and Training
Daytime bladder control typically improves over the first 6 to 12 months after surgery. Nighttime continence is harder to achieve and may keep improving through the second year. The reason nighttime is trickier: the pelvic floor muscles that help hold urine in relax while you sleep, and the neobladder fills continuously. Many people set an alarm to wake and empty the neobladder during the night, especially in the first year. Pelvic floor exercises, taught before you leave the hospital, are a core part of the training process and make a measurable difference in how quickly continence improves.
How Doctors Decide Which Option Fits
Current guidelines from both the American Urological Association and the European Association of Urology say that all three options should be discussed with every patient undergoing bladder removal. The choice depends on several factors. Heart, lung, and cognitive function all play a role, along with your social support system and personal preference.
Age matters too. A neobladder generally works best in younger, healthier patients. Research presented at the 2024 American Urological Association meeting identified 70 as the age after which quality-of-life scores tend to drop with a neobladder compared to simpler diversions. European guidelines cite 80 as the threshold beyond which a neobladder is generally not recommended, though there’s no hard cutoff. Certain anatomical requirements also apply: if the cancer involves the urethra, a neobladder isn’t an option because there’s no safe place to connect it.
An ileal conduit is the fastest surgery and has the simplest recovery, making it the go-to choice for patients with significant health concerns or limited dexterity (since it doesn’t require self-catheterization or complex voiding techniques). An Indiana pouch suits people who want to avoid an external bag but aren’t candidates for a neobladder.
Long-Term Complications to Watch For
All three diversion types use intestinal tissue in ways it wasn’t designed for, which creates some predictable long-term issues. A large study of over 1,000 patients with ileal conduits found that about 17% developed infections such as kidney infections or recurrent urinary tract infections, typically within the first two years. Roughly 15% developed kidney or conduit stones, and about 10% experienced a metabolic imbalance caused by the intestinal lining reabsorbing substances from urine that the body had already filtered out. These rates are broadly similar across all diversion types, though the specific patterns vary.
Vitamin B12 deficiency can develop over time because the section of intestine used for the diversion is the same part that normally absorbs this vitamin. Regular blood work helps catch this early. Stomal complications, like the stoma narrowing or the skin around it breaking down, affect a meaningful number of people with conduits and Indiana pouches and sometimes require minor revisions.
For neobladder patients, the most common ongoing challenge is nighttime leakage. Some people manage it with absorbent pads, others with timed alarms. A small percentage of neobladder patients find they can’t empty the pouch effectively through abdominal pressure alone and need to use intermittent catheterization through the urethra, essentially combining the neobladder with a self-catheterization routine.
