Continent Urinary Diversion
Continent urinary diversion is surgery to make a new way for urine to pass out of the body. The surgery may be needed if your bladder is diseased or damaged. During the surgery, a new bladder (neobladder) may be created. Or an internal pouch may be created. This is done using a piece of your own intestine (bowel).
Two types of urinary diversion
To collect urine inside your body, you may have a neobladder or an internal pouch. Your doctor will discuss which option is best for you. A different option involves creating a tube that continually drains urine into an external bag. This is called a urostomy.
Neobladder. A neobladder allows urine to follow the usual path out of the body. With a neobladder, you’ll no longer have nerves that signal when your bladder is full. You will need to empty the bladder on a set schedule. To do this, you use your pelvic and abdominal muscles to help push the urine out of your body. In some cases, you pass a thin tube (catheter) through the urethra into the new bladder to drain urine.
Internal pouch. A pouch connects on one end to the tubes (called ureters) that bring urine from the kidneys to the bladder. The other end of the pouch connects to a small, permanent opening (stoma) made in the wall of the abdomen. A valve is created surgically to prevent urine leakage. Most of the time, the stoma is covered with a small bandage. To empty urine from the pouch, you pass a catheter through the stoma into the pouch. This is done on a set schedule. Unlike with some treatments, no bag is needed to collect urine.
Preparing for surgery
Prepare for the surgery as you have been told. In addition:
Tell your doctor about all medicines you take. This includes prescription medicines and over-the-counter medicines, vitamins, herbs, and other supplements. It also includes any blood thinners, such as warfarin, clopidogrel, or daily aspirin. You may need to stop taking some or all of them before surgery.
Follow any directions you are given for not eating or drinking before surgery. This includes coffee, water, gum, and mints. (If you have been instructed to take medicines, take them with a small sip of water.)
If you have been told to, prepare your bowel for surgery (called bowel prep). This process begins 1 to 2 days before the surgery. Your doctor may tell you to limit your diet to clear liquids. You may also be asked to take laxatives or to give yourself an enema. Follow all instructions you are given.
The day of surgery
The surgery takes 4 to 5 hours. Afterward, you will stay in the hospital for 5 to 7 nights.
Before the surgery begins:
An IV (intravenous) line is put into a vein in your arm or hand. This delivers fluids and medicines such as antibiotics. In some cases, a central or arterial line is inserted into a vein somewhere else on the body. Your doctor can tell you more.
You may be given a medicine to prevent blood clots in your veins.
To keep you pain-free during the surgery, you’re given general anesthesia. This medicine puts you into a state like deep sleep through the surgery. A tube may be inserted into your throat to help you breathe.
You may have an epidural to help control post-surgery pain. A small tube is inserted into your back to deliver pain medicine that numbs the lower body. Talk to your doctor or anesthesiologist about this option.
During the surgery:
A catheter may be placed into your bladder through your urethra.
An incision is made in the abdomen.
The bladder may be left in place or it may be removed.
For a neobladder, a piece of the small intestine is removed. It is attached to the ureters on one end and to the urethra on the other end.
For a pouch, the end of the small intestine and first part of the large intestine is removed. A stoma is made in the wall of your lower belly. The piece of intestine is then connected to the ureters on one end and to the stoma on the other.
When the surgery is complete, the incision in the abdomen is closed with stitches or staples.
A small tube (drain) may be placed in the abdomen to help remove excess blood and fluid.
Thin tubes (stents) may be placed through the abdomen into the ureters to the kidneys. These help drain urine during healing.
If you have a neobladder, a catheter may be placed into it to help drain urine. If you have a pouch, a catheter may be placed through the stoma into the pouch to keep the pathway open. Another catheter may be placed through the abdomen into the pouch to help drain mucus and urine.
Recovering in the hospital
After the surgery, you will be taken to a recovery room. Here, you’ll wake up from the anesthesia. You may feel sleepy and nauseated. If a breathing tube was used, your throat may be sore at first. When you are ready, you will be taken to your hospital room. While in the hospital:
You will be given medicine to manage pain. Let your providers know if your pain is not controlled.
You’ll first receive IV fluids. In a day or so, you will start on a liquid diet. You will then slowly return to a normal diet.
As soon as you’re able, you will get up and walk.
You’ll be taught coughing and breathing methods to help keep your lungs clear and prevent pneumonia.
A nurse or doctor will show you how to care for your new bladder or pouch and stoma. You’ll also learn how to care for any drains and tubes that you have. You may be taught to flush your pouch with fluid, to remove mucus.
Recovering at home
After your hospital stay, you will be released to an adult family member or friend. Have someone stay with you for the next few days, to help care for you. Recovery time varies for each person. Your doctor will tell you when you can return to your normal routine. Until then, follow the instructions you have been given. Make sure to:
Take all medicine as directed.
Care for your incision as instructed. If you go home with a drain or catheter, take care of them as you were shown.
If you have a stoma, care for it as instructed.
Follow your doctor’s guidelines for showering. Don't swim, take a bath, use a hot tub, or do other activities that cause the incision to be covered with water until your doctor says it’s OK.
Not do any heavy lifting or strenuous activities as directed.
Not drive until your doctor says it’s OK. Don’t drive if you’re taking medicines that make you drowsy.
Walk a few times daily. As you feel able, slowly increase your pace and distance.
Not strain to pass stool. If needed, take stool softeners as advised by your doctor.
Do pelvic (Kegel) exercises as directed.
When to call your healthcare provider
Call your healthcare provider right away if you have any of the following:
Fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider
Symptoms of infection at an incision site, such as increased redness or swelling, warmth, worsening pain, or foul-smelling drainage
Pain, redness, swelling, odor, or drainage at the stoma site
Little or no urine output for longer than 4 hours
Burning or pain when passing urine or frequent need to pass urine
Bloody urine with clots
Problems with any drains, stents, or catheters
Nausea or vomiting that doesn’t go away
Pain that cannot be controlled with medicine
Call 911 if you have chest pain or trouble breathing.
You will have follow-up visits so your doctor can check how well you’re healing. Sutures, staples, or tubes will be removed. You may be taught how to drain your pouch using a catheter. If you have a neobladder, you may be taught pelvic floor exercises to strengthen the muscles around it. This helps prevent urine leakage. You and your doctor can also discuss any further treatment you may need.
Risks and possible complications
Bleeding (you may need a blood transfusion)
Pneumonia or other lung problems
Abnormal levels of vitamins or minerals in the blood, requiring lifelong medicine
Backup of urine in the ureters and kidneys
Problems with the neobladder or pouch
Development of stones in the neobladder or pouch
Problems with the stoma
Scarring and narrowing of the ureters
Risks of anesthesia. The anesthesiologist will discuss these with you.
