Chronic Kidney Disease: Catching It Before Dialysis
Kidney function can fall to a quarter of normal without producing a single symptom. Two inexpensive tests find it years earlier — and almost nobody asks for them.

Anantapur's summer produces a predictable surge in kidney stone admissions. Recurrence is common — and largely preventable with changes most people can sustain.
Why this region sees so many
Kidney stones form when urine becomes concentrated enough for minerals to crystallise. In a district where summer temperatures routinely exceed 42°C and a large share of the population works outdoors, fluid loss through sweat is enormous and urine output falls accordingly.
Add a diet often high in salt and low in citrus, plus a tendency to drink only when thirsty, and the conditions for stone formation are close to ideal. Recurrence rates without preventive measures are high — roughly half within five to ten years.
Recognising an attack
- Severe pain in the loin radiating to the groin, coming in waves
- Restlessness — unlike abdominal inflammation, the patient cannot find a comfortable position
- Nausea and vomiting
- Blood in the urine, visible or microscopic
- Burning urine and frequency if the stone is near the bladder
- Fever with the pain — this is an emergency indicating infection behind an obstruction
Worth knowing
Loin pain with fever means a possibly infected, obstructed kidney. This needs emergency drainage, not painkillers and a wait-and-see approach.
Prevention that works
- Drink enough to pass 2–2.5 litres of urine a day — in summer that usually means 3–4 litres of intake
- Judge by urine colour: pale straw is the target, dark yellow means you are behind
- Reduce salt to under 5 g a day — high salt increases calcium excretion into the urine
- Add citrus: lemon juice in water daily provides citrate, a natural stone inhibitor
- Moderate animal protein — excessive meat raises uric acid and lowers citrate
- Do not restrict dietary calcium; low calcium intake paradoxically increases oxalate absorption and stone risk
- Reduce very high-oxalate foods only if you form calcium oxalate stones: spinach, beetroot, nuts, chocolate, strong tea
- For uric acid stones, reduce organ meat, red meat and alcohol
Treatment options
Stones under about 5 mm frequently pass spontaneously with good hydration, pain control and medication that relaxes the ureter. Larger stones, or those causing obstruction, infection or unrelenting pain, need intervention.
Ureteroscopy with laser fragmentation is used for ureteric and many kidney stones. Percutaneous nephrolithotomy is used for large kidney stones. A double-J stent is often placed temporarily to keep the ureter open, and its removal is a short procedure — do not forget it, as a retained stent causes serious problems.
After passing a stone
Collect the stone if possible — strain your urine through a fine sieve — and send it for analysis. Knowing whether it is calcium oxalate, uric acid, struvite or cystine allows genuinely specific prevention rather than generic advice.
A 24-hour urine study and a metabolic evaluation are worthwhile for anyone with recurrent stones, a single kidney, a family history, or stones at a young age.
Key takeaways
- Aim for pale straw-coloured urine — that usually means 3–4 litres of fluid daily in summer.
- Reduce salt and add lemon juice; do not restrict dietary calcium.
- Loin pain with fever is an emergency requiring urgent drainage.
- Send any passed stone for analysis so prevention can be specific.
