Urogen HARC Lectures Flashcards
- Kidneys
- Renal Plexus Autonomic
- Sympathetic (T10-T11)
- Coeliac ganglion & plexus
- Aorticorenal ganglion
- Least splanchnic nerve
- First lumbar splanchnic nerve
- Kidneys
- Renal Plexus Autonomic
- Parasympathetic
• Posterior Vagal Trunk (Vagus Nerve)
- Kidneys
- Renal Plexus Autonomic
- Sensory (Visceral Afferents)
- Conveyed to CNS via sympathetic fibres
- Referred pain at T10-T11
Innervation
- Adrenal Glands
- Renal Plexus
- Sympathetic (T10-L1)
- Coeliac plexus and greater splanchnic nerves.
- Coeliac ganglion
- Unusually, synapse occurs in medulla
- Promotes secretion of adrenaline and noradrenaline from the medulla into the bloodstream
What are the ureter lined with?
Urothelium
What is the action called when the ureters passes urine from kidneys to bladder?
Peristaltic action
• Ureteric plexus
- Branches from three plexuses
- Renal & aortic (Upper)
- Superior hypogastric (Intermediate)
- Inferior hypogastric (Lower)
What are the three points of ureteric constriction?
- Ureteropelvic junction
- Pelvic brim - As it crosses the common iliac a.
- Vesicoureteral junction
What is the common site of lodged kidney stones?
Ureter
What are the causes of Urinary Tract Stones?
- Dehydration, diet and disease
- Urine saturation with salts and varied pH
- Constriction sites
What are the symptoms of Urinary Tract Stones?
Renal Colic
- Haematuria
- Urinary urgency
Urinary Tract Stones (Calculi) are classified based on position. What are these positions?
- Nephrolithiasis (Kidney)
- Uretrolithiass (Ureter)
- Cystolithiasis (Bladder)
What are the complications of urinary tract stones?
- Urinary obstruction
- Infection
- Renal failure
•Staghorn Calculus
Staghorn calculi refer to branched stones that fill all or part of the renal pelvis and branch into several or all of the calyces. They are most often composed of struvite (magnesium ammonium phosphate) and/or calcium carbonate apatite.
In the male urethra there a four parts what are they?
- Pre-prostatic 1 → Bladder to prostate
- Prostatic 2 → Length of the prostate
- Membranous (Muscular) 3 → Deep perineal pouch
- Penile/Spongy 4 → Deep perineal pouch to external urethral orifice
- Pre-prostatic 1
- Prostatic 2
- Membranous (Muscular) 3
- Penile/Spongy 4
Urethra Catheterisation
- Allows bladder drainage if patient cannot urinate.
- Biological sex of the patient must be considered - Differences in urethral length and course
- If urethra cannot be catheterised, bladder can be drained via suprapubic catheter
What forms the pelvic floor?
• Levator ani and coccygeus m
Pelvic floor separates the ____ _____ from ______
Pelvic floor separates the pelvic cavity from perineum
The pelvic FLoor
- Provides supports and prevents prolapsing of pelvic viscera - Bladder, uterus and rectum
- Separately identifying parts of levator ani is difficult due to fibres blending together.
