What is a Mitrofanoff?
A Mitrofanoff is a procedure described by French Surgeon Professor Paul Mitrofanoff in 1976. The procedure was intended to enable the emptying of the bladder via a continent catheterisable channel, known as the Mitrofanoff, in patients who were unable to void in the normal way or where ISC was not a viable option.
Also known as a Continent Urinary Diversion or Appendico-vesicostomy, the Mitrofanoff channel has been used successfully for many years allowing patients the freedom to live their lives without the encumbrance of an indwelling catheter or a permanent stoma bag.
The Mitrofanoff channel is created usually out of a segment of appendix or small bowel (sometimes fallopian tube can be utilised) which has been isolated but retains a viable blood and nerve supply. This channel is tunnelled into the bladder where a continent non-return valve is constructed and brought out onto the surface of the abdomen enabling the intermittent drainage of urine via a disposable catheter.
Bladder Augmentation (Augmentation Cystoplasty)
This procedure involves the enlargement of an otherwise small capacity bladder where small bowel is used to create a much larger capacity bladder.
Following this procedure the bladder muscle is unable to contract and empty in the normal way and patients may need to perform intermittent self-catheterisation (ISC) via the urethra to ensure that the bladder is emptied completely at regular intervals.
Bladder Augmentation with Mitrofanoff
In some cases it may not be possible to empty the bladder via the urethra and a Mitrofanoff continent catheterisable channel may be constructed to enable regular emptying via a small opening on the abdominal wall. A disposable catheter is inserted via the ‘stoma’ at regular intervals, usually every three hours.
Mucus, is a natural secretion or lubricant which is present in bowel and may be evident in the urine when bowel has been used to enlarge or augment the bladder. The mucus may occasionally cause blockage of one or more of the catheter drainage eyes resulting in a diminished flow of urine.
A catheter which has 4 drainage eyes rather than two may help to reduce the risk of blockage and allow free drainage which helps to prevent the risk of urinary infection.
Catheters
There are many catheters which can be used to empty the bladder via the Mitrofanoff channel. Some catheters are non-coated and made from medical grade PVC which require the use of a water soluble gel for lubrication prior to catheterising.
Other catheters have a hydrophilic coating which must be hydrated with water before use. Many have an integral water source. Some catheters have 4 drainage eyes which help to prevent the risk of blockage by mucus in the urine.
All catheters have a coloured funnel at the end to distinguish between sizes and which can be used to attach a drainage bag or some form of collection device if required.
Some patients may be advised to leave their catheter in situ overnight and attach the funnel to the drainage system. Hydrophilic coated catheters are not recommended to be left insitu overnight. Your Mitrofanoff healthcare professional is the best person to advise you.
