Renal colic and ureteral colic present with sudden, unilateral pain that progressively increases in intensity. The pain is throbbing, aching, and gnawing, originating from the flank and radiating to the genitalia and thigh. Associated symptoms include dysuria, intermittent pain, hematuria, nausea, vomiting, fever, and hypotension in severe cases. The mechanism involves increased pressure in the urinary tract from obstruction, dilating the renal pelvis which can lead to kidney atrophy over time. Renal colic presents as dull, visceral pain in the flank radiating to the front, lasting 5-10 minutes or hours. Fever, leukocytosis, and protein in the urine indicate potential

COLIC

2. URETERAL COLIC PAIN: (con dau quan
than)
O: sudden,unilateral, progressively
increasing in an episode
P: patients struggle to find a relieved
position
Q: throbbing, aching, gnawing
R: from flank subcostal, lumbar region-
radiates along reflection of ureter to
genitalia, medial thigh
S: 7-8 VAS
T: lasts 5-10 minutes or even for hours
A:
+ dysuria (tiểu buốt)
+ intermittent (tiểu ngập ngừng)
+ pain in bladder reflected region and
sometimes in rectum
+ hematuria (tiểu máu)
+ nausea, vomiting: associated symptoms
of vicerla pain
+ fever>38 C, tachycardia, hypotension potential
sepsis, UTI
+ oliguria: <500ml/24h (anuria <100ml/24h)

3. Mechanism: suddenly pressure increase in urinary tract in upper of obstruction site
+ Acute obstruction in uterter dilation of renal pelvis and calyces, may result in kidney atrophy
+ The high pressure in the pelvis is transmitted back through the collecting ducts into the
cortex, causing renal atrophy, but it also compresses the renal vasculature of the medulla,
causing a diminution in inner medullary blood flow
+ pressure increasing intra ureter lumen  trigger the muscular layer to increase
constriction frequency also trigger the pain receptor.

5. RENAL COLIC PAIN: (đau hố sườn lưng)
O: sudden (acute), constantly painful
(chronic)
P:
Q: dull, visceral pain
R: most painful site- flank subcostal, lumbar
region- radiates to the front toward
umbilicus or no radiation
S:
T: lasts 5-10 minutes or even for hours
A:
+ high fever, chills, elevated Leukocytes.
Leukocyte and protein in urine  potential
acute inflammation in kidney pelvis (viem

tay quanh than)  vo hong lung (+)
Mechanism:
Distension of renal capsule or renal pelvis:
When there is an obstruction in colleting
system, intr -Bowman capsule pressure rises
deacrease filtrate pressure  sensed by
juxtaglomerular system  activate RAAS system
 increase in renal blood flow  worsening the
situation due to more fluid escaping the
capilaries into interstial space
