What Are Kidney Stones?


Kidney Stone
A stone located within the kidney. It may be symptomatic or found incidentally on imaging.

Ureteric Stone
A stone that has moved into the ureter and may cause colicky pain, obstruction or urinary symptoms.

Single or Multiple Stones
Some patients have one stone, while others may have stones in both kidneys or recurrent episodes over time.

Recurrent Stone Disease
Repeated stone formation may justify additional metabolic evaluation and prevention planning based on individual risk.
Common Symptoms of Kidney or Ureteric Stones
Severe Flank / Side Pain
Sudden pain in the side or back, often coming in waves.
Pain Radiating to Groin
Pain may travel towards the lower abdomen or groin.
Blood in Urine
Urine may appear blood-stained or blood may be detected on testing.
Nausea / Vomiting
Severe stone pain can be associated with nausea or vomiting.
Urinary Symptoms
Burning, frequency or urgency can occur, especially with lower ureteric stones.
Reduced Urine / Difficulty Passing Urine
Difficulty passing urine or reduced urine output can occur in selected situations.
Causes and Risk Factors Can Differ Between Patients
Low Fluid Intake / Concentrated Urine
Insufficient fluid intake or high fluid loss can lead to more concentrated urine and may increase stone risk.
Previous or Family History
People who have formed stones before, or who have a family history of stone disease, may have a higher risk of recurrence.
Dietary & Metabolic Factors
Dietary patterns, excess salt intake and selected metabolic abnormalities can influence stone formation in susceptible individuals.
Urinary Infection
Certain infection-related stones can develop in association with urinary tract infection.
Medical / Anatomical Factors
Selected medical conditions, urinary tract abnormalities or problems with urine drainage can contribute to stone formation.
Medicines & Genetic Conditions
Some medicines and uncommon inherited disorders can contribute to specific stone types and may require targeted evaluation.
How Kidney Stones Are Evaluated

Clinical Assessment
Symptoms, previous stone episodes, medicines, medical conditions, previous procedures and relevant family history are reviewed.

Urine Testing
Urinalysis and, when indicated, urine culture can help assess blood in urine and possible infection.

Blood Tests
Kidney function and selected blood parameters may be checked depending on the clinical situation.

Imaging
Ultrasound, X-ray or non-contrast CT may be used according to the patient, urgency and clinical question. CT is particularly useful for defining stone size, location and density in many adult patients.

Stone Analysis / Metabolic Evaluation
If a stone is recovered, analysis may help identify its composition. Selected recurrent or high-risk patients may need additional metabolic evaluation, including urine studies.
Treatment Depends on the Stone and the Patient
Active Treatment May Be Considered When
✓ The stone is unlikely to pass spontaneously
✓ Pain remains significant or recurrent despite appropriate treatment
✓ There is persistent obstruction or concern about kidney function
✓ Infection is associated with obstruction
✓ The stone is growing or causing repeated clinical problems
✓ The patient’s anatomy, occupation, travel needs or other clinical circumstances favour active treatment
✓ A large or complex renal stone is present
From Observation to Minimally Invasive Stone Removal
Observation & Symptom Control
Selected stones can be monitored when spontaneous passage is reasonable and there is no urgent indication for intervention. Follow-up is important.
Shock Wave Lithotripsy (SWL)
Shock waves can fragment selected stones from outside the body. Effectiveness depends on stone size, location, density, anatomy and equipment availability.
RIRS
Flexible ureteroscopy is used to reach selected stones inside the kidney through the natural urinary passage without a skin incision.
Medical Expulsive Therapy
Ultrasound, X-ray or non-contrast CT may be used according to the patient, urgency and clinical question. CT is particularly useful for defining stone size, location and density in many adult patients.
URSL / Ureteroscopy
An endoscope is passed through the urinary tract to reach and treat selected ureteric stones, often using laser fragmentation where appropriate.
PCNL
A keyhole tract is created through the back to access the kidney. PCNL is commonly used for larger or complex renal stones and is a guideline-supported first-line option for many stones larger than 2 cm. [Link: /pcnl/]
Urgent Drainage
When an obstructed kidney is infected or urgent decompression is otherwise required, a ureteric stent or nephrostomy may be used before definitive stone treatment.
Individualised Planning
Stone location, size, density, anatomy, infection, kidney function, blood-thinning medicines, previous treatment and patient preference all influence the treatment plan.
RIRS vs URSL vs PCNL
URSL
Often used for selected ureteric stones. The ureteroscope reaches the stone through the urinary passage; fragmentation and/or extraction may be performed.
RIRS
Flexible endoscopic access to the kidney through the urinary tract. Commonly considered for selected renal stones where this approach is clinically suitable.
PCNL
Percutaneous keyhole access directly into the kidney. Commonly used for larger, complex or high-burden renal stones; EAU guidance supports PCNL as first-line treatment for renal stones >2 cm.
Which is right?
There is no single “best” procedure for every stone. Selection depends on stone and patient factors, expected clearance, procedural risks, need for staged treatment and local expertise.
Before & After a Stone Procedure
Before Treatment
Review imaging and symptoms; check urine for infection when indicated; review blood tests and kidney function when required; discuss medicines including blood thinners; explain anaesthesia, procedure-specific risks and expected recovery; discuss whether a temporary ureteric stent may be required.
After Treatment
Follow prescribed medicines and hydration advice; recovery instructions differ by procedure; temporary urinary symptoms can occur after instrumentation or stent placement; seek medical advice for fever, worsening pain, inability to pass urine or other concerning symptoms; attend follow-up and discuss stone analysis/prevention when relevant.
Prevention Starts with Understanding Your Stone Risk

Hydration
Maintain regular fluid intake through the day unless a clinician has advised fluid restriction for another medical condition.

Balanced Diet
Avoid extreme “stone diets.” Prevention should be based on the stone type and individual metabolic findings where available.

Salt Awareness
High salt intake can influence urinary calcium handling; moderation may be advised as part of an individual prevention plan.

Stone Analysis
If a stone is available, laboratory analysis can help guide stone-specific prevention.

Metabolic Evaluation
Recurrent or high-risk stone formers may benefit from additional blood and urine assessment.

Follow-Up
Imaging and clinical follow-up may be recommended depending on residual stones, recurrence risk and the treatment performed.
Kidney Stones in Special Situations

Pregnancy
Evaluation and treatment require special attention to imaging and medication safety. Ultrasound is generally preferred as first-line imaging.

Children
Stone disease in children may require paediatric-specific imaging, metabolic evaluation and treatment planning.

Single Functioning Kidney
Symptoms or obstruction may need more urgent assessment because preserving drainage and kidney function is especially important.

Recurrent Stones
Repeated stone formation may justify stone analysis, metabolic assessment and a structured prevention plan.

Urinary Infection
Fever or infection with obstruction requires urgent assessment; definitive stone treatment may need to follow drainage and infection control.

Blood-Thinning Medicines
Procedure selection and timing may be affected by anticoagulant or antiplatelet therapy. Medicines should not be stopped without medical advice.
A Structured Approach to Kidney Stone Evaluation and Treatment

Review Symptoms & Reports
Previous imaging, laboratory tests, prescriptions, procedure records and current symptoms are reviewed.

Confirm the Clinical Problem
Stone location, burden, obstruction, infection risk and kidney function are assessed using appropriate investigations.

Discuss Options
Observation, medical management, SWL or endourological treatment options are discussed when relevant to the patient’s situation.

Plan Treatment
If intervention is required, the procedure is selected according to expected benefit, risk, anatomy and patient needs.

Recovery & Prevention
Follow-up includes recovery guidance, evaluation of residual/recurrent stones where appropriate and recurrence-prevention advice.
Have Kidney Stone Reports? Start with a Structured Review
Patients outside Aligarh may use online consultation for selected needs such as review of CT/ultrasound reports, discussion of an existing diagnosis, second-opinion questions, post-treatment follow-up or guidance before planning an in-person visit. Imaging itself may still need to be reviewed directly, and some symptoms or clinical situations require urgent or in-person assessment.

Report Review
Share available imaging reports, laboratory results, discharge summaries and previous procedure details.

Second Opinion
Discuss a proposed stone procedure and understand why a particular approach may have been recommended.

Pre-Visit Planning
Clarify which reports and records may be useful before travelling to Aligarh for assessment.

Follow-Up
Selected recovery and report-review discussions may be suitable for online follow-up when clinically appropriate.
