Week 7: Urinary and Kidney Flashcards
Structures of the Renal System
Kidneys and Nephrons x2
Ureters x2
Bladder
Urethra
Male Prostate
Nephrons ____
filter
Are the left and right kidneys perfectly symmetrical?
No, the left kidney is higher than the right one because of the location of the liver
Functions of the Kidney
- Urine Formation:
Glomerular Filtration
Tubular Reabs and Secretion
- Regulation Functions:
Osmolarity and water excretion
Lyte and AcideBase Balance
BP (RAA System)
RBC Production (Erythropoietin)
Vitamin D Synthesis
Secretion of Prostaglandins
- Waste Excretion
End products of metabolism, bacterial toxins, water soluble drugs, and drug metabolites
Urine storage (bladder) and emptying
As a risk factor, childhood diseases can lead to what possible renal/urologic disorder
chronic kidney disease
As a risk factor, advanced age can lead to what possible renal/urologic disorder
incomplete bladder emptying, etc
As a risk factor, cystoscopy or catheterization can lead to what possible renal/urologic disorder

What information should be taken upon reanl/urologic assessment in the health history
Chief Complaint
Pain (Reason, pattern, intensity, what makes it worse or better etc)
Past health history (hx of UTi, tests, renal angiograms, caths, STDs, etc)
Family Hx
Social Hx (Habits and behaviors)
Voiding Patterns (when is normal, how much, smell, at night a lot?)
Medications (What is taken, what may affect UO/micturation/renal toxicity)
What is an important bit of information to teach elderly patients about their renal function
to drink plenty of water everyday even if they are not thirsty as it is good for their renal function
What information should we gather about renal system pain patterns
Is the pain from distention, obstruction, or inflammation of renal tissue?
Are we discovering these diagnoses when they seek care for other symptoms?
Are they experiencing any pain even?
Is absence of pain or symptoms for issues lik STIs common
yes 50% of people wont even report pain or symptoms
When is a lot of renal/urologic issues and diagnoses found
they tend to be found when clients are seeking care for other symptoms like for a cold
Urinary Frequency
voiding more than every 3 hours
Urinary Urgency
Having a strong desire to void
Dysuria
Painful urination
Urinary Hesitancy
delay in initiation
Nocturia
excessive urination at nightr
Incontinence
Involuntary loss of urine
Enuresis
Bed wetting
Polyuria
increased volume of urine
Oliguria
UO less than 500 mL a day
Anuria
Less than 50 mL of UO a day
When are oliguria and anuria most common
chronic renal failure
Hematuria
RBC in urine
Proteinuria
Protein in urine (should not be there)
The most accurate indicator of fluid loss or gain in patients who are acutely ill is ___
weight
Areas of Emphasis for the Renal/Urologic Physical Exam
Abdomen Suprapubic Region Genitalia Lower Back Lower Extremities
KIDNEYS - Not always palpable
Bladder percussion
Areas of Edema
Checking DTRs and Gait
Renal dysfunction may produce tenderness…
at the CVA (can very rarely palpate the kidney here too)
Why are DTRs and Gait checked with renal physical exams
Because the peripheral nerve innervating the bladder also innervates the lower extremities
What are some possible urine colors to find in patients and what do they mean
Colorless/Pale Yellow - Dilute Urine, Alcohol, Lots of Fluid Intake
Yellow/Milky White - pyuria, vaginal cream
Bright Yellow - mult vitamin preparations
Pink/Red - Hgb breakdown, RBCs, blood, certain drugs
Blue/Blue Green - dyes and certain pseudomonas species
Orange/Amber - concentrated urine, dehydration, fever, bile, meds
Brown/Black - old blood, very concentrated urine, iron, certain compounds
It is important to document ____ and ____ of urine
color and amount
What are some urinary diagnostic tests commonly seen
Urinalysis and Urine Culture
Renal Fxn Tests: Specific Gravity and 24 hour Urine Test
Serum Tests: Creatinine, BUN, BUN:Creatinine
Biopsy
Another name for 24 hour urine test is…
creatinine clearance test
What is normal urine specific gravity
1.010 - 1.025
Urine C&S is often used for suspected ___
UTIs
Some of the most common urologic nursing diagnosese are…
- Knowledge Deficits
- Pain r/t infection, edema, obstruction, bleeding along tract, etc
- Fear for potential alteration in renal function and embarassment s/t urinary function
Normal BUN:Creatinien ratio
10:1
What is the process of urine collection/clean catch (midstream)
- Nurse has pt wash genitals and perineal area prior w/ soap and water
- Males: Void directly into container; Females - Hold container between legs
- Begin voiding, then place specimen container in stream of urine and collect 30-60 mL
How should males clean their genitals prior to a clean catch
clean the meatus and head of penis with a circular motion
Use each towelette (3 total) once
How should females clean their genitals prior to a clean catch
front to back
use each towelette (3 total) once
What is the gold standard of urine collection for determining renal fxn
24 hour urine collection
How does a 24 hour urine collection work
A special orange speciment container with a preservative is obtained from the lab in order to collect urine (unless the pt has an indwelling catheter)
Signs are posted in the client room, chat, and bathroom regarding all urine needing to be collected in the next 24 hours
Client will void and discard the first urination at the start of the 24 hour period and then begin collecting everything after that
Once 24 hours is up container is put on ice and the client should void one last time to collect that urine before being sent to the lab
What are some diagnostic imaging tests for urinary function / renal function
KUB (Kidney Ureter Bladder Radiograph) - Likea kidney x ray
US - high frequency waves through the body - non invasive
CT - 3D image
Bladder Scan 0- INjectible scan
MRI
IVP - intravenous polygraphy - injectnle dye and X rays of the kidney/urinary tract
Nuclear Scans
Cystography - small cystoscope goes in and looks
Renal Angiography - injectible medium looks at renal blood flow
What is needed before any diagnostic test
consent form signed
What is needed before urologic testing using contract sgents
- have emergency equipment ready for anaphylactic shock and double check for allergies to things like iodine and shellfish
- Informed consent
- Know kidney baseline function because some dyes can cause more injury
* If a renal angiograph, catheter may need to be inserted first

Urinary Retention
Inadequate bladder emptying disorder
Residual urine stays in the bladder after voiding and can result in overflow incontinence
Results of Urinary Retention
Overflow Incontinence
Urinary Stasis –> Bacterial Growth –> Infection/Stones
If urinary retention is left untreated what will happen
A UTI will begin or possible stone formation
Etiology of Urinary Retention
Detrusor fxn deficit

Inspection Percussion Palpation
Nursing Dx for Urinary Retention
THINK OBSTRUCTION:
Risk for INfection …
Risk for Renal Calculi…
Urinary retention r/t detrusor fxn deficit …
Goals for urinary retneiton are based on …
the nursing diagnoses
thinking obstructions you want to address risk for infection and calculi but also work on that retention itself
Interventions for Urinary Retention
