This document provides information on neurogenic bladder. It begins with the anatomy and physiology of normal bladder function controlled by the brain and spinal cord. It then defines neurogenic bladder as any bladder dysfunction caused by disruption of normal bladder innervation, which can be congenital or acquired.
The main types of neurogenic bladder are described as spastic or flaccid, depending on whether the lesion is above or below the lumbosacral spinal cord. Causes include spinal cord injury, multiple sclerosis, and congenital conditions. Symptoms vary between types but include issues with storage and emptying of urine. Treatment aims to preserve kidney function and typically involves medications, injections, or surgery to manage symptoms. Ayurved

4. Anatomy and physiology
Anatomically, the bladder which consists of smooth
muscle, and the base, which includes the trigone and
bladder neck that are intimately connected to the pelvic
floor.
The bladder outlet has two urethral sphincters, the
internal (smooth muscle) sphincter and the external
(striated muscle) sphincter.
Females have a less complex urethral sphincter
mechanism that surrounds a shorter urethra.

Regulation of micturition involves cortical, subcortical,
spinal cord, and bladder mechanisms ,
Cortical control areas in the frontal and cingulate gyri as
well as subcortical areas provide inhibitory influence on
micturition at the level of the pons and excitatory
influence on the external urinary sphincter.
This allows voluntary control of micturition so that
normally bladder evacuation can be delayed until an
appropriate time and place to void are chosen.
The pontine micturition center (PMC, also known as
Barrington’s nucleus or M-region) is essential for the
coordination of micturition.
6. Cont…
Normal voluntary micturition includes bladder filling,
storage, and emptying .
The kidneys filtering 180L per day though only
approximately 800 to 2000 ml per day is excreted as
urine.
This filtrate is transported through the ureters to the
bladder. The ureters, which are approximately 25–
30cm in length, pass obliquely through bladder wall at
the ureterovesicular junction to form a one-way valve
that serves to prevent retrograde reflux of urine to the
kidneys during bladder filling and emptying stages.

10. Introduction
Neurogenic bladder refers to all types of bladder dysfunction caused
by an interruption of normal bladder innervation. Condition may
be congenital or acquired
No cure but can be managed
Subsequent complications include:
urinary incontinence, residual urine retention, urinary tract
infection, calculi formation, and renal failure.
A neurogenic bladder can be –
1. spastic (hypertonic, reflex, or automatic),
2. flaccid (hypotonic, atonic, nonreflex, or autonomous)
Most cases managed with medication and surgical treatment.
The primary goal of the physician is to maintain and preserve renal
function!
11. Definition
Neurogenic bladder is the name given to a number of urinary conditions in
people who lack bladder control due to a brain, spinal cord or nerve
problem.
This nerve damage can be the result of diseases such as multiple sclerosis
(MS), Parkinson's disease or diabetes. It can also be caused by infection of
the brain or spinal cord, heavy metal poisoning, stroke, spinal cord injury,
or major pelvic surgery. People who are born with problems of the spinal
cord, such as spina bifida, may also have this type of bladder problem.
12. Type 1- spastic(reflex or automatic) neurogenic
bladder caused by UMNL
Any lesion of the cord above the voiding reflex arc.
Most common cause are trauma,tumor & MS.
Voiding is interrupted,involuntary,& incomplete.
Hypertrophy of the detrusor develops,often leading to
vesicourethral reflux.
Dilatation of the internal sphinter occur.
The external sphincter and perineal muscles becomes spastic &
obstructive,causes incearsed resistance to the flow urine and
results in an impaired stream and residual urine.
13. Uninhibited neurogenic bladder
(mild spastic NB)
These type of NB may develop following a cerebral vascular
accident or arteriosclerotic degeneration in spinal cord.
It may occur as the first sign of MS.
The lesion is centered either in the inhibitory centers of cortex
or in pyramidal tract (UMN).
Therefore,facilitative impulse passing continually down the
cord keep sacral centers so excitable that even a small
quantity of urine elicits an uncontrollable micturation
reflex,thereby promoting frequent urination.
14. Spastic type NB showing: ‘Christmas tree’ or ‘pine
tree’ effect.heavy trabeculation,cellules and small
diverticula in cystography
15. Type 2- Flaccid (atonic/nonreflex or autonomous)
neurogenic bladder
It will caused by lower motor neuron lesion.
Most common cause of flaccid neurogenic bladder is
trauma,tumors,herniated intervertebral disks,tabes
dorsalis,poliomyelitis & congenital defect.
Vesical dysfunction arises when there is injury to center of
micturition in cord (S2-4), cauda equina, sacral roots or nerve
there by interrupting the sacral reflex arc.
Loss of perception of fullness permits overstretching of the
detrusor and atony of the muscle and these contributes to weak
and inefficient detrusor contraction.

Underactive bladder-bladder is unable to signal when
full
27. Pharmacologic Interventions
Tricyclic Antidepressant Drugs :
Imipramine not only reduces bladder tone through its strong
anticholinergic effects and antispasmodic properties but it
also increases bladder internal sphincter tone through α-
adrenergic agonist effect to further facilitate urine storage.
Additionally, imipramine has a local anesthetic effect on
bladder mucosa, which may further reduce bladder
contractility through spinal reflex mechanisms.
28. Cont…
Anticholinergic (Antimuscarinic) Medications:
This class of medication reduces reflex (involuntary) detrusor activity by
blocking cholinergic transmission at muscarinic receptors and is the first-line
option for treating neurogenic detrusor overactivity (NDO)
Cholinergic Agonists:
Urecholine is a synthetic muscarinic agonist with no significant nicotinic
effects. It can be used to promote detrusor contraction in lower motor neuron
lesions.
Alpha-2 Adrenergic Agonists:
This class of medications can be used in neurogenic bladder dysfunction when
the internal urinary sphincter is spastic, which occurs with detrusor sphincter
dyssynergia in upper motor neuron bladder dysfunction
29. Surgical Interventions
Procedures to Enhance Detrusor Storage :
Neuromodulation for Neurogenic Detrusor Overactivity.
Enterocystoplasty.
Bladder Sphincter Procedures to Enhance Emptying :
Sphincterotomy
Urethral Stents and Balloon Dilatation
Sling surgery
