Definition



Kidney Stones are small, hard deposits of mineral
and acid salts on the inner surfaces of the kidneys
Alternative names include:
 Renal Lithiasis
 Renal Calculi
 Nephrolithiasis (Kidney Stone Disease)
Stones are classified by their location in the urinary
system and their composition of crystals.
Statistics

Incidence Rate:




More than 1 million cases annually in US
1 in 272 or 3.6 per 1000 Americans develop
stones annually.
80% of stones under 2mm in size
90% of stones pass through the urinary
system spontaneously

Generally stone smaller than 6mm are passable

More common in woman than men.
Commonly a result of UTI.
Uric Acid

Most common
Caused by high protein diet and gout.

Case Study

It is a hot summer day, and you are an RN in the emergency
department (ED). S.R., an 18-year-old woman, comes to the ED
with severe flank and abdominal pain and N/V. S.R. looks very
tired, her skin is warm to touch, and she is perspiring. She paces
about the room doubled-over and is clutching her
abdomen. S.R. tells you that the pain started early this morning
and has been pretty steady for the past hours. She gives a
history of working outside as a landscaper and takes little time for
water breaks. Her past medical history (PMH) includes 3 kidney
stone attacks, all during late summer. Exam findings are that her
abdomen is soft and w/o tenderness, but her left flank is
extremely tender to touch, palpation, and percussion. You place
S.R. in one of the examination rooms and take the following VS
118/98, 90, 20, 99 F. UA shows RBC of 50 to 100 on voided
specimen, WBC 0.






What questions do you need
to ask before a patient has an
IV pyelogram?
Answer:

Do you have a history of renal failure?


Have you ever have a reaction to iodine?



Contrast contains iodine
Is there a possibility you could be pregnant?
Are you currently taking any medications?



Contraindicated with renal failure
Metformin may react with contrast
Contrast contains iodine
Check BUN and Creatinine levels prior to IVP
Nursing Diagnosis:
Acute pain r/t obstruction from renal calculi as
manifested by patient being doubled-over,
pacing around the room, and patient
verbalizing pain upon assessment.
Goal: patient will state pain is at a manageable level
within 2 hours of admission.
What are Nursing Interventions?
Nursing Goal/Interventions:

Administer pain medication as ordered by physician.

Provide non-pharmaceutical techniques such as imagery and/or
meditation to relieve pain.

Patient will determine manageable pain level.

Patient will be asked about any concerns and/or fears that may be
associated with pain.

Provide emotional support for the patient.

Reassess patient’s pain levels within 1 hour after administration of
pain medications.
Nursing Diagnoses:
Deficient knowledge r/t fluid requirements and dietary
restrictions as manifested by reoccurring stones.
Goal: Patient will state methods to prevent future stones by the time
patient is D/C. A plan of care will also be created with the
patient before patient is D/C to prevent reoccurrence of kidney
stones.
Risk for infection r/t kidney stone obstruction of urinary tract
causing stasis of urine.
Goal: Patient’s urine will be yellow and clear upon D/C and patient
will not have a fever. UA with show no indication of UTI or
other infection.
What are Nursing Interventions?
Treatment

Two Focuses of Treatment:



Treatment of acute problems, such as pain, n/v, etc
Identify cause and prevent kidney stones from reoccurring
Acute Treatment:







Pain Medication!!!

Keep Hydrated
Ambulation
Diet Restrictions
Emotional Support
Invasive Procedure (may be necessary)

Journal Article #1




Purpose: Determine effectiveness of an herbal supplement
made out of varuna and banana stems, “Herbmed,” on kidney
stones
Study: 77 patients participated in a randomized, placebo,
double-blinded study that was conducted in India from July 2007
to February 2008. Two groups were formed: Group A with calculi
5-10mm and Group B with calculi >10mm.
Results: Patients relieving the herbal supplement showed a
33% reduction in the size of their kidney stone.
Conclusion: Herbmed is an herbal treatment that may have
promising effects in reducing kidney stone size and expulsion.
Journal Article #2




Purpose: To determine the possible effects fructose has on the
formation of kidney stones.
Study: The researchers looked at three different cohorts (older
woman, younger women, and men) over combined 48 years of
follow up. 4902 new symptomatic kidney stones were documented
among these three cohorts.
Results: The results from the study showed that there is a positive
correlation between the intake of fructose and the development of
kidney stones.
Conclusion: Fructose intake can increase insulin resistance which
lowers the pH in the urine and increases ones’ risk for the
development of uric acid kidney stone. Nurses need to adequately
assess the patient’s diet and educate patients on ways to prevent
stones.
Journal Article #3




Purpose: The study looked specifically at anxiety associated with
treatment, surgery, for kidney stones.
Study: The anxiety of 66 patients was assessed before and after
treatment, using three forms of measurement tools: palmar sweat
test, visual analogue scale, and Speilberger state anxiety
questionnaire. The two groups that were compared were open
surgery to minimally/non-invasive treatment.
Results: The results from the study showed no significant change in
the questionnaire answers between the three indicators of anxiety.
But, there was a fair reduction in the analogue scores postoperatively in-patients who had open surgery. These same patients
also had a lower palmar sweat response. But, pre-operatively
patients who going to have open surgery had higher analogue
scores.
Conclusion: The two primary causes of anxiety were pain and
being under anesthesia. Open surgery treatment resulted in lower
levels of anxiety than non-invasive treatments.
