The Boari flap technique reshapes part of the bladder wall into a tube to replace a damaged ureter segment, while appendiceal ureter interposition uses the appendix as a substitute for the ureter. For more extensive reconstruction, the ileal ureter approach repurposes a segment of the small intestine (ileum) to create a new channel for urine ...

Chronic urinary retention that is due to bladder blockage which can either be as a result of muscle damage or neurological damage. [7] If the retention is due to neurological damage, there is a disconnect between the brain to muscle communication, which can make it impossible to completely empty the bladder. [ 7 ]
A urethral stricture is a narrowing of the urethra, the tube connected to the bladder that allows urination. The narrowing reduces the flow of urine and makes it more difficult or even painful to empty the bladder. [1] Urethral stricture is caused by injury, instrumentation, infection, and certain non-infectious forms of urethritis. The ...
Fecal incontinence or constipation occurs when there is a problem with normal bowel functioning. This could be for a variety of reasons. The normal defecation pathway involves contractions of the colon which helps mix the contents, absorb water and propel the contents along. This results in feces moving along the colon to the rectum.

Functional anal stenosis disappears under anesthesia, whereas true anal stenosis does not. The main symptoms of anal stenosis are difficult evacuation of stool, narrow stools, painful defecation, need for self-digitation to achieve defecation, bleeding from anal tears, and constipation.
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. [1] [2] There are multiple types of neurogenic bladder depending on the underlying cause and the symptoms.
Rigidity (involuntary contraction of the abdominal muscles) is the most specific exam finding for diagnosing peritonitis. [14] If focal peritonitis is detected, further work-up should be done. If diffuse peritonitis is detected, then urgent surgical consultation should be obtained, and may warrant surgery without further investigations.
