When a kidney stone is an emergency
Come to the emergency department if you have stone pain with fever or chills, if you cannot pass urine at all, if the pain is uncontrollable, or if you are vomiting persistently. Fever with stone pain can mean an infected, obstructed kidney — that becomes dangerous quickly and needs urgent drainage, not antibiotics at home.
When a kidney stone is an emergency
The four situations above. Also come in urgently if you have only one working kidney, a transplanted kidney, or you are pregnant.
The pattern of pain
The classic description, and it is classic because it is consistent:
- Starts suddenly, often in the night or early morning
- Located in the side or back, below the ribs
- Comes in waves — building to an intense peak, easing, then building again
- Radiates downward and forward, towards the lower abdomen and groin
- Moves as the stone moves: pain lower down often means the stone has travelled towards the bladder
- You cannot find a comfortable position. This is quite characteristic — people with stone pain pace and shift constantly, unlike, say, peritonitis where people lie very still
The intensity is often described as the worst pain the person has experienced, including by people who have given birth.
Other symptoms
- Blood in the urine — pink, red or brown. Sometimes only visible on testing
- Pain or burning on passing urine, particularly once the stone is near the bladder
- A persistent urge to pass urine, often producing very little
- Nausea and vomiting, which accompany severe pain
- Cloudy or strong-smelling urine, which can suggest infection
- Restlessness and sweating during an episode
Symptoms you might not expect
No symptoms at all. Stones sitting quietly in the kidney frequently cause nothing, and are found incidentally on a scan done for another reason.
Only mild ache. Not every stone produces dramatic pain — some cause a dull, persistent flank discomfort that gets attributed to muscular strain for weeks.
Testicular or labial pain. As the stone moves down, pain can refer to the groin and genitals, which sometimes sends people to the wrong department.
Symptoms mimicking other things. Stone pain has been mistaken for appendicitis, gallstones, gastritis and gynaecological problems — which is why imaging settles it rather than argument.
Why summer in Faridabad matters
Stones form when urine is concentrated. In North Indian summers, with outdoor work and heavy sweating, urine concentrates far more than people realise — and stone presentations rise accordingly.
If you have had a stone before, the hotter months are exactly when fluid intake needs to go up rather than stay the same. The target is straightforward: urine pale enough that you would describe it as almost colourless, all day.
What happens next
Assessment is quick and follows a predictable path: pain relief first, then a urine test, then imaging to establish the size and position of the stone and whether it is obstructing the kidney.
That imaging determines everything. Small stones are often given time and fluids to pass; larger or obstructing stones are treated actively. Our kidney stone treatment page covers the options, and kidney stones covers causes and prevention.
One practical request: if you pass a stone, keep it. Having it analysed tells us which type you form, and that turns generic prevention advice into specific advice.
