An Indiana pouch is a surgically-created urinary diversion used to create a way for the body to store and eliminate urine for patients who have had their urinary bladders removed as a result of bladder cancer, pelvic exenteration, bladder exstrophy or who are not continent due to a congenital, neurogenic bladder. This particular urinary diversion results in a continent reservoir that the patient must catheterize to empty urine. This concept and technique was developed by Drs. Mike Mitchell, Randall Rowland, and Richard Bihrle at Indiana University.^[1]

Description

With this type of surgery, a reservoir, or pouch, is created out of approximately two feet of the ascending colon and a portion of the ileum (a part of the small intestine). The ureters are surgically removed from the bladder and repositioned to drain into this new pouch. The end of the segment of small intestine is brought out through a small opening in the abdominal wall called a stoma. Since a segment including the large and small intestines is utilized, also included in this new system is the ileocecal valve. This is a one-way valve located between the small and large intestines. This valve normally prevents the passage of bacteria and digested matter from re-entering the small intestine. Originally, it was thought that removing the ileocecal valve from the digestive tract would likely result in diarrhea, but this has not shown to be the case ^{[ according to whom? ]}. After a period of several weeks, the body adjusts to the absence of this valve (from the digestive tract) by absorbing more liquids and nutrients. Importantly, this valve, in its new capacity, will now effectively prevent the escape of urine from the stoma. The passage of the conduit through the abdominal wall allows the rectus abdominis muscle to aid with continence.^{[ citation needed ]}

Recovery and function

The surgery itself along with recovery time depends on the patient. Robotic surgery can take approximately 6–12 hours. A patient's time in the hospital can take 7–10 days if no complications present themselves. Depending on the type of surgery the abdominal incision for this surgery may be up to eight inches in length and is typically closed with staples on the outside and several layers of dissolvable stitches on the inside. After surgery, patients will have three drainage tubes place while tissues heal: one through the newly created stoma, one through another temporary opening in the abdominal wall into the pouch, and an SP tube (to drain non-specific post-surgical abdominal fluid). In the hospital, the SP tube and external staples will be removed, after several days. The remaining two tubes will each be connected to collection bags worn on each leg and the patient is usually sent home like this. After sufficient healing, and another doctor's visit, the tube will be removed from the stoma. The patient will now begin to catheterize the pouch every two hours. Since one other tube will still be in place, patients can still sleep through the night, since a larger collection bag is attached to that tube at night time. After approximately one month, patients will return to the hospital for a special x-ray. Dye will be instilled into the pouch to verify that there is no leakage of urine. If there is no leakage, this last tube will be removed. Emptying time now may be increased to 3 hours, however, now the patient will need to wake up during the night (every 3 hours) to empty the pouch. Over time, emptying time can possibly be increased up to 4–6 hours. Although to decrease the potential for infections and deterioration of the pouch it is best to continue to cath every 3–4 hours. The pouch will continue to expand and will reach its final size at approximately six months. The pouch will then hold up to 1,200 cubic centimeters (cc). Depending on your doctor's orders, each day, the pouch may need to be irrigated with 60 cc of sterile water in an effort to remove membrane mucus, salts, and bacteria. It can take 6–12 months for your body to adjust to the Indiana pouch.

Advantages

In contrast to other urinary diversion techniques, such as the ileal conduit urinary diversion, the Indiana pouch has the advantage of not using an external pouch adhered to the abdomen to store urine as it is created inside of the body. The urine is drained through a small stoma that is barely visible. This can result in a better body image and broader clothing options. Also, there will not be the worry of an external urostomy appliance coming loose and leaking. The Indiana pouch will require sterile catheters to insert into the stoma to drain the urine every 3–4 hours. To avoid a possible fatal infection, a new sterile intermittent catheter should be used each time and not reused.^[2] As with the urostomy appliances, the cost of intermittent catheters can be significant, and both are not usually covered fully by most health insurance plans. Plus, as with the external urostomy appliance, the catheter supply will need to be monitored to see how many appliances are left before ordering more and waiting for them to be shipped. The long-term financial costs to the recipient of the Indiana pouch and other urinary diversion techniques are both substantial. Although notably, the Indiana pouch is the most viable option for maintaining a lifestyle similar to prior the surgery because of the ability to move freely from fear of rupturing an external device plus the ability to continue most of the same activities.^{[ citation needed ]}

Treatment

Indiana pouch surgery can be done in very young patients, as long as they understand how to catheterize the pouch and can empty the pouch on a schedule. Indiana pouch surgery also has been successful in patients of advanced ages, also as long as they are able to empty and irrigate the pouch on a schedule. Some patients, after having had an ileal conduit, requiring an external appliance, have opted to have the Indiana pouch, as elective surgery. Such a surgery is usually recommended, if possible, since it has been documented that the Indiana pouch may reduce the possibility of kidney damage because the ureters are repositioned lower in the abdomen. This positioning reduces the possible back-flow of urine to the kidneys. After having an Indiana pouch surgery, patients may choose to wear a medical alert medallion indicating they have an Indiana pouch.

Possible complications and side effects

Patients who have an Indiana pouch run the risk of infections from the stoma, difficult catheterization, pain around the stoma, stones, leakage, and sleep disruption. Also this type of urinary diversion causes immediate metabolic changes that can give a wide range of symptoms from diarrhea, vitamin B12 deficiency, electrolyte abnormalities, hepatic metabolism, and possible bone health deterioration. Over the lifetime of the Indiana pouch, the recipient should have their kidney function closely monitored.^[3]

Cystoscopy is endoscopy of the urinary bladder via the urethra. It is carried out with a cystoscope.

Urinary incontinence (UI), also known as involuntary urination, is any uncontrolled leakage of urine. It is a common and distressing problem, which may have a large impact on quality of life. It has been identified as an important issue in geriatric health care. The term enuresis is often used to refer to urinary incontinence primarily in children, such as nocturnal enuresis. UI is an example of a stigmatized medical condition, which creates barriers to successful management and makes the problem worse. People may be too embarrassed to seek medical help, and attempt to self-manage the symptom in secrecy from others.

In urinary catheterization, a latex, polyurethane, or silicone tube known as a urinary catheter is inserted into the bladder through the urethra to allow urine to drain from the bladder for collection. It may also be used to inject liquids used for treatment or diagnosis of bladder conditions. A clinician, often a nurse, usually performs the procedure, but self-catheterization is also possible. A catheter may be in place for long periods of time or removed after each use.

A colostomy is an opening (stoma) in the large intestine (colon), or the surgical procedure that creates one. The opening is formed by drawing the healthy end of the colon through an incision in the anterior abdominal wall and suturing it into place. This opening, often in conjunction with an attached ostomy system, provides an alternative channel for feces to leave the body. Thus if the natural anus is unavailable for that function, an artificial anus takes over. It may be reversible or irreversible, depending on the circumstances.

<span class="mw-page-title-main">Urinary retention</span> Inability to completely empty the bladder

Urinary retention is an inability to completely empty the bladder. Onset can be sudden or gradual. When of sudden onset, symptoms include an inability to urinate and lower abdominal pain. When of gradual onset, symptoms may include loss of bladder control, mild lower abdominal pain, and a weak urine stream. Those with long-term problems are at risk of urinary tract infections.

In anatomy, a stoma is any opening in the body. For example, a mouth, a nose, and an anus are natural stomata. Any hollow organ can be manipulated into an artificial stoma as necessary. This includes the esophagus, stomach, duodenum, ileum, colon, pleural cavity, ureters, urinary bladder, and renal pelvis. Such a stoma may be permanent or temporary.

Ileostomy is a stoma constructed by bringing the end or loop of small intestine out onto the surface of the skin, or the surgical procedure which creates this opening. Intestinal waste passes out of the ileostomy and is collected in an external ostomy system which is placed next to the opening. Ileostomies are usually sited above the groin on the right hand side of the abdomen.

In urology, a Foley catheter is one of many types of urinary catheters (UC). The Foley UC was named after Frederic Foley, who produced the original design in 1929. Foleys are indwelling UC, often referred to as an IDCs. This differs from in/out catheters. The UC is a flexible tube if it is indwelling and stays put, or rigid if it is in/out, that a clinician, or the client themselves, often in the case of in/out UC, passes it through the urethra and into the bladder to drain urine.

Cystectomy is a medical term for surgical removal of all or part of the urinary bladder. It may also be rarely used to refer to the removal of a cyst. The most common condition warranting removal of the urinary bladder is bladder cancer.

A urostomy is a surgical procedure that creates a stoma for the urinary system. A urostomy is made to avail for urinary diversion in cases where drainage of urine through the bladder and urethra is not possible, e.g. after extensive surgery or in case of obstruction.

<span class="mw-page-title-main">Mitrofanoff procedure</span>

The Mitrofanoff procedure, also known as the Mitrofanoff appendicovesicostomy, is a surgical procedure in which the appendix is used to create a conduit, or channel, between the skin surface and the urinary bladder. The small opening on the skin surface, or the stoma, is typically located either in the navel or nearby the navel on the right lower side of the abdomen. Originally developed by Professor Paul Mitrofanoff in 1980, the procedure represents an alternative to urethral catheterization and is sometimes used by people with urethral damage or by those with severe autonomic dysreflexia. An intermittent catheter, or a catheter that is inserted and then removed after use, is typically passed through the channel every 3–4 hours and the urine is drained into a toilet or a bottle. As the bladder fills, rising pressure compresses the channel against the bladder wall, creating a one-way valve that prevents leakage of urine between catheterizations.

<span class="mw-page-title-main">Suprapubic cystostomy</span> Surgical procedure to drain urine

A suprapubic cystostomy or suprapubic catheter (SPC) is a surgically created connection between the urinary bladder and the skin used to drain urine from the bladder in individuals with obstruction of normal urinary flow. The connection does not go through the abdominal cavity.

An ileal conduit urinary diversion is one of various surgical techniques for urinary diversion. It has sometimes been referred to as the Bricker ileal conduit after its inventor, Eugene M. Bricker. It is a form of incontinent urostomy, and was developed during the 1940s and is still one of the most used techniques for the diversion of urine after a patient has had their bladder removed, due to its low complication rate and high patient satisfaction level. It is usually used in conjunction with radical cystectomy in order to control invasive bladder cancer.

Posterior urethral valve (PUV) disorder is an obstructive developmental anomaly in the urethra and genitourinary system of male newborns. A posterior urethral valve is an obstructing membrane in the posterior male urethra as a result of abnormal in utero development. It is the most common cause of bladder outlet obstruction in male newborns. The disorder varies in degree, with mild cases presenting late due to milder symptoms. More severe cases can have renal and respiratory failure from lung underdevelopment as result of low amniotic fluid volumes, requiring intensive care and close monitoring. It occurs in about one in 8,000 babies.

<span class="mw-page-title-main">Ureteral stent</span> Medical device

A ureteral stent, or ureteric stent, is a thin tube inserted into the ureter to prevent or treat obstruction of the urine flow from the kidney. The length of the stents used in adult patients varies between 24 and 30 cm. Additionally, stents come in differing diameters or gauges, to fit different size ureters. The stent is usually inserted with the aid of a cystoscope. One or both ends of the stent may be coiled to prevent it from moving out of place; this is called a JJ stent, double J stent or pig-tail stent.

Urinary diversion is any one of several surgical procedures to reroute urine flow from its normal pathway. It may be necessary for diseased or defective ureters, bladder or urethra, either temporarily or permanently. Some diversions result in a stoma.

A urine collection device or UCD is a device that allows the collection of urine for analysis or for purposes of simple elimination. UCDs of the latter type are sometimes called piddle packs.

Neurogenic bladder dysfunction, often called by the shortened term neurogenic bladder, refers to urinary bladder problems due to disease or injury of the central nervous system or peripheral nerves involved in the control of urination. There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms. Symptoms include overactive bladder, urinary urgency, frequency, incontinence or difficulty passing urine. A range of diseases or conditions can cause neurogenic bladder including spinal cord injury, multiple sclerosis, stroke, brain injury, spina bifida, peripheral nerve damage, Parkinson's disease, multiple system atrophy or other neurodegenerative diseases. Neurogenic bladder can be diagnosed through a history and physical as well as imaging and more specialized testing. In addition to symptomatic treatment, treatment depends on the nature of the underlying disease and can be managed with behavioral changes, medications, surgeries, or other procedures. The symptoms of neurogenic bladder, especially incontinence, can severely degrade a person's quality of life.

A ureterostomy is the creation of a stoma for a ureter or kidney.

Nils G. Kock was a professor of surgery who taught and practiced at the University of Gothenburg, Gothenburg, Sweden. Kock was noted for his research, experimentation, and colorectal surgical techniques. These led to his breakthrough development of the Kock pouch, used for people who require excretory stomas.
