EXCRETORY SYSTEM
RENAL CALCULI (
KIDNEY STONES ) Also known as Nephrolithiasis.
Calculi are formed
when urine becomes saturated with calcium or uric acid crystals.
Age and sex: Calculi
are most common between ages of 30 and 60 years.
Kidney stones
are more common in males but infection stones are more common in women
of child bearing age.
CAUSE:
-
Infection in
the urinary tract.
-
Urinary tract
obstruction due to hydronephrosis.
-
Excess of calcium
,oxalate or cystine in urine due to less fluid intake and other
medical conditions.
-
Dehydration due
to less fluid intake which ultimately leads to concentrated urine
with presence of stone forming crystals.
TYPES OF STONES:
-
Calcium oxalate
is the most common type of stone usually found in men, occurs due to
reduced urine volume and increase in urinary calcium.
-
Calcium
phosphate stones are formed with hypercalciuria in an alkaline urine
in case of renal tubular acidosis.
-
Struvite stones
are found in urine with ph >7.5 in patients having chronic urinary
tract infection.
-
Uric acid stones
are formed when there is increased production of relatively
insoluble uric acid in case of patients suffering from gout, severe
psoriasis or malignancy.
-
Cystine calculi
are formed due to inborn error of metabolism where urine becomes
saturated with cystine and results in stone formation.
SYMPTOMS:
-
Cramping, sharp,
excruciating pain , fluctuating in intensity associated with
vomiting and sweating.
-
Pain extends from
loin to groin radiating to testes in males and labia majora in
women.
-
Haematuria :
Presence of blood in urine with or without colic.
-
Painful
urination.
-
Difficulty in
starting to urinate. Urine flows, then stops and again flows.
-
Persistent urge
to urinate, increase in the frequency of urination.
INVESTIGATIONS:
-
Urine analysis
shows presence of red blood cells in the urine.
-
Ultrasound scan.
-
Abdominal X ray
(Plain X ray- K U B region, i.e. Kidney, ureter and bladder)
-
I.V. P. – Intravenous pyelogram.
-
C.T Scan of abdomen.
-
M.R. I. (
Magnetic resonance imaging)
MANAGEMENT:
-
Drink atleast 6
to 8 glasses of water in a day which will help to pass the stone
through urine.
-
Medications
should be given if the patient develops renal colic.
-
Prevent
recurrence by altering the diet and treating the underlying cause.
-
Avoid non
vegetarian food in case of uric acid stones.
-
Avoid chocolates,
nuts in case of calcium and phosphate stones.
-
Avoid tomatoes,
guava, beetroot and spinach.
HOMEOPATHIC
MANAGEMENT OF RENAL CALCULI
Homeopathy offers
great relief to patients with renal calculi as homeopathic medicines
help in passing the stone through urine and also prevent its recurrence.
Homeopathic remedies also relieve the colicky pain which the patient
experiences off and on until the stone is passed out.
