Clinical Applications in the Renal System Flashcards
The ureters run directly over what muscles?
psoas muscle
where do renal lymphatics drain?
renal lymphatics drin the capsule and parenchyma. they flow into the pre-aortic nodes before traveling up the throacic duct and into the subclavian vein.
what is the role of renal lymphatics?
what is the critical component of lymphatic drainage from the urinary system?
they aid in the clearance of waste products of the kidneys and clearance of electrolytes, infectious products, or antibiotic products
the synchornous motion of the thoracic and pelvic diaphragms is a critical component of lymphatic drainage.
what are some consequences of imaired lymphatic flow?
impaired lymphatic flow increases oncotic interstitial pressure and disrupts the countercurrent exchange eventually leading to a decreased ability to concentrate urine properly.
this ends up with an increased risk of kidney dmage because of ureteral obstruction
What is the sympathetic innervation for:
kidney:
Ureters:
Bladder:
Urethra:
What is the sympathetic innervation for:
kidney: T10-L1
Ureters: T10-L1
Bladder: T10-L1
Urethra: L1-L2
What effect does INCREASED sympathetic tone have on the kidney?
Increased sympathetic tone on the kidney
- increases the sodium transport across the tubule walls and directly increases the release of renin from he JGA
- vasoconstriction of afferent arterioles → decreased GFR → decreased urine volume
What is the effect of chronic sympathetic stimulation on the kidney?
Chronic sympathetic stimulation results in retention of fluid and causes chronically elevated arterial pressure and essential hypertension
What is the parasympathetic innervation to:
Kidney
Ureters:
Bladder:
Urethra:
Parasympathetic innervation to
kidney: vagus
Ureters: proximal 2/3 of ureters= vagus/ distal 1/3 is S2-S4
bladder: pelvic splanchnic nerves S2-4
urethera: S2-S4
What is the effect of INCREASED Parasympathetic tone on:
- kidney:
- ureters:
- Bladder:
- Urethera:
INCREASED Parasympathetic tone on:
- kidney: not known
- ureters: increased peristalsis
- Bladder: parasympathetic stimulation ocurs during voiding. Increased bladder wall tone (excitatory activity to the detrusor muscle and inhibitory on the trigone)
- Urethera: relaxation of the urethera
What nerves transmit the sense of bladder fullness?
visceral afferents transmit impulses to the L1-L2 spinal nerves
where does the voluntary relaxation of the external urethral sphincter come from?
impulses from S2-S4 is parasympathetic along with sympathethc relaxation to the sphincter
What is the effect of DECREASED parasympathetic tone to the GU:
decreased parasympathic tone results in
incomplete emptying of the bladder
impotence
tightening of internal urinary sphincter
UTI
- osteopathic considerations:
- treatment:
- osteopathic considerations for a UTI: rule out pubic symphysis and pelvic floor somatic dysfunction. Infection can result in incomplete emptying, reflux, and loss of normal ureteal peristalsis (increased sympathetic tone)
- treatment:
- appropriate antibiotics
- treatment of pelvic floor somatic dysfunction
- Treatment of T10-L2 and SI joint
Nephrolithiasis:
- sympathetic/parasympathetic innervation
- treatment:
Nephrolithiasis:
- innervation:
- sympathetic: T10-L1
- parasympathetic innervation: vagus and S2-S4 (upper and lower ureters)
- treatment: inhibit paraspinals T10-S2 (decrease ureteral spasm and aid in movement of stone), treat chapman’s points, improve lymphatic drainage
Pyelonephritis:
- Definition:
- Innervation:
- sympathetic:
- parasympathetic:
- Treatment:
Pyelonephritis:
- Definition: an upper urinary tract infection involving the renal parenchyma and collecting. Can become chronic
- Innervation:
- sympathetic: T10-L1/2
- parasympathetic: vagus
- Treatment: antibiotics. OMT to T10-L2 and OA. Decrease sympathetic tone and reflex to involved areas
