RENAL COLIC,RENAL CALCULUS.- Renal colic is the name commonly applied to the symptoms which arise when a renal calculus either passes or attempts to pass down the ureter.
A renal calculus is a concretion formed by the deposit of one or more of the solid constituents of the urine. It differs only in size from the gritty particles called “gravel” It may be single or there may be many. It is generally composed of uric acid or exalt of lime.
Symptoms and Diagnosis-The first indication of a stone passing down the ureter is a violent pain commencing in the loin of one or other side and passing round the side to the region of the bladder in front. The pain may rise to intense agony and give rise it fainting or vomiting. Sometimes the urine itself shows little change. Sometimes there is blood present,giving the urine a smoky or porter like appearance.
An attack of renal colic may be mistaken for a bilious attack, intestinal colic, or appendicitis. If there is blood in the urine it will distinguish renal colic from all these. In appendicitis there is fever and local tenderness. In bilious attacks and intestinal colic the fever is less definitely located. It may be mistaken for lumbago, but this is rarely one- sided and its pains is more definitely muscular and influenced by movement.
General Treatment.–In general an anti-gout dietary and regimen should be followed. Water should be drunk freely, but not a hard water. Vichy water, Ems water, and Malvern water are good. Alcohol must be avoided in all forms, and more especially beers. Tea must be taken only in moderation.
During an attack hot fomentations to the seat of the pain will give relief and assist the passage of the calculus, and the fomentations will be more effective if made with a compress of poppy-heads and chamomile flowers.
Medicines.–(Every ten minutes till the pain is relieved.)
–Writhing, cramping pains. Patient must keep moving about.
–Violent sticking pains extending from kidneys to bladder.
Urtica ur. 0.
