ESWL Surgery at Apollo Hospitals, Lucknow

Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive, day-care treatment for kidney and upper ureteric stones that uses focused shock waves to break stones into fragments small enough to pass in the urine. At Apollo Hospitals Lucknow (Apollomedics Super Speciality Hospital, Kanpur?Lucknow Road), ESWL is offered within a full-service Urology and Nephrology programme, so that if a stone turns out to be unsuitable for shock wave treatment, RIRS, ureteroscopy or PCNL can be arranged in the same institution without a second referral.

Why Patients Choose Apollo Hospitals Lucknow for ESWL

• A full-spectrum stone service, not a single machine. ESWL, ureteroscopy (URSL), Retrograde Intrarenal Surgery (RIRS) with flexible scopes and laser, mini-PCNL and standard PCNL are available under one roof, so the plan can be changed if imaging or stone density suggests ESWL will not work well.
• Experienced urology team. A dedicated consultant-led Urology and Renal Sciences department with senior urologists, supported by nephrology, interventional radiology and a 24x7 dialysis unit ? important for patients whose stone disease has already affected kidney function.
• Apollo Group legacy. Apollo Hospitals has operated in India since 1983 and runs one of the country's largest multi-city hospital networks, with standardised clinical protocols, infection-control audits and NABH-accredited processes carried across units.
• Imaging that decides the right treatment. On-site multi-slice CT (for non-contrast CT KUB, stone size, Hounsfield density and skin-to-stone distance), ultrasound, digital X-ray and laboratory services allow same-visit assessment for out-of-town patients.
• Metabolic stone-prevention support. Because roughly half of stone formers form another stone within 5?10 years, the team offers 24-hour urine and blood metabolic evaluation, stone analysis where fragments are retrieved, and dietitian-led dietary counselling adapted to North Indian vegetarian and non-vegetarian diets.
• Care across age groups. Protocols are adapted for children (lower energy settings, paediatric anaesthesia support), for adults, and for older patients with diabetes, hypertension, cardiac disease or anticoagulant use, in coordination with cardiology and internal medicine.
• 24x7 emergency and critical care backup for the small number of patients who develop obstruction, fever or steinstrasse after fragmentation.
• Insurance and TPA desk on site to handle cashless pre-authorisation, CGHS/ECHS/Ayushman-type panel queries where applicable, and documentation for reimbursement.

Overview

Extracorporeal Shock Wave Lithotripsy (ESWL) is a non-invasive procedure designed to treat kidney stones effectively. At Apollo Hospitals Lucknow, we aim for high standards in stone care, using current lithotripsy technology and structured protocols to give patients the best reasonable chance of a good outcome. Our urologists provide individualised care and explain each step of the treatment journey, including what ESWL can and cannot achieve, so that decisions are made with full information rather than expectation.

ESWL is performed without any cut on the body. The patient lies on a lithotripsy table, the stone is located using X-ray (fluoroscopy) or ultrasound, and shock waves generated outside the body are focused on the stone. Around 2,000?4,000 shocks are usually delivered in one sitting. Sedation or analgesia is generally used; general anaesthesia is more common in children.

Why ESWL Surgery is Necessary

Kidney stones can cause severe pain and discomfort, and can lead to complications if left untreated. ESWL uses shock waves to break stones into smaller fragments that can pass more easily through the urinary tract. Its main advantages are:

• Non-invasiveness: Unlike traditional surgical methods, ESWL requires no incision, which usually means a shorter recovery and a lower risk of wound-related infection.
• Quick recovery: Most patients return to routine activities within a few days.
• Relief from stone-related pain: By fragmenting the stone, ESWL addresses the cause of renal colic in suitable patients and can improve quality of life.

At Apollo Hospitals Lucknow, our urologists assess each case individually to confirm whether ESWL is the most suitable option for that particular stone, or whether an endoscopic procedure would be more reliable.

Risks of Delay

Postponing treatment of an obstructing or growing stone can lead to significant problems:

• Infection: A blockage can lead to urinary tract infection, and an infected obstructed kidney is a medical emergency requiring urgent drainage.
• Kidney damage: Prolonged obstruction can cause hydronephrosis and irreversible loss of function in that kidney, sometimes silently.
• Increased pain and harder treatment: Larger and older stones become harder, less responsive to shock waves, and more likely to need endoscopic surgery.

Timely assessment matters. If you have flank pain, blood in the urine, burning urination with fever, or a stone already reported on ultrasound, consult a urologist rather than waiting for symptoms to settle on their own.

Benefits of ESWL Surgery

• Good success rates in well-selected stones: Published series and guideline reviews report stone-free rates broadly in the range of 70?90% for small, lower-density stones in the renal pelvis or upper ureter, falling considerably for large, hard or lower-pole stones. Individual results vary.
• Minimal discomfort: Most patients report less pain than after endoscopic or percutaneous surgery.
• Short hospital stay: ESWL is usually a day-care procedure, and many patients go home the same day.
• Preservation of kidney function: Clearing obstruction promptly helps protect the affected kidney from progressive damage.
• No anaesthesia in many adults: Sedation and analgesia are often sufficient, which is useful for patients with anaesthetic risk factors.

What Current Guidelines Say

Treatment selection at Apollo Hospitals Lucknow follows internationally recognised urolithiasis guidance, read alongside Indian practice:

• The Urological Society of India (USI) promotes evidence-based stone management through its national and zonal academic programmes, and Indian urological practice broadly aligns with EAU and AUA recommendations, with adaptation for India's high stone-belt prevalence and hot-climate dehydration.
• The European Association of Urology (EAU) Guidelines on Urolithiasis, 2024 edition, recommend ESWL or ureteroscopy as first-line options for most renal stones under 20 mm and for many ureteric stones, while favouring ureteroscopy/RIRS or PCNL for larger, harder or lower-pole stones. A notable shift over recent editions is the stronger position of flexible ureteroscopy for lower-pole and 10?20 mm stones, where ESWL clearance is less predictable.
• The American Urological Association (AUA) / Endourological Society Surgical Management of Stones guideline (2016, amended 2019) similarly lists ESWL and ureteroscopy as standard options for stones =20 mm, and recommends against ESWL in pregnancy, uncorrected bleeding disorders and untreated urinary infection.
• Guidelines also stress non-contrast CT KUB before treatment, because stone density (Hounsfield units, generally >1000 HU predicting poorer fragmentation) and skin-to-stone distance strongly influence whether ESWL will succeed.
• Medical expulsive therapy with alpha-blockers is now recommended selectively ? mainly for distal ureteric stones larger than about 5 mm ? rather than for all stones, a change from older practice.

Where the evidence is uncertain, such as the exact number of sessions any individual will need, we say so and review after each sitting.

Who is Suitable for ESWL ? and Who is Not

ESWL Compared With Other Stone Treatments

Timing of the Procedure and the Preparation Phase

ESWL is a planned procedure in most cases. A typical pathway at Apollo Hospitals Lucknow is:

1. Consultation and imaging (Day 0): History, examination, urine routine and culture, blood tests including creatinine and coagulation profile, and non-contrast CT KUB or ultrasound with X-ray KUB.
2. Infection clearance: If the urine culture is positive, antibiotics are given and the culture repeated. ESWL is not performed with active infection.
3. Medication review: Aspirin, clopidogrel, warfarin or newer anticoagulants usually need to be stopped for a defined period after discussion with the treating physician or cardiologist. Never stop these on your own.
4. Optional pre-stenting: A DJ stent may be placed beforehand for large stones, solitary kidney or when obstruction is present.
5. Procedure day: Reporting time is usually early morning, fasting as instructed. The session itself takes roughly 45?60 minutes; total hospital time is commonly 4?6 hours.
6. Repeat sessions: If needed, these are generally spaced about 1?2 weeks apart for renal stones, allowing tissue recovery and fragment clearance.

Additional Procedures Sometimes Done at the Same Time

• DJ stent insertion or removal ? to protect drainage before ESWL or to remove a stent placed earlier.
• Cystoscopy ? occasionally required for stent manipulation or to assess the bladder.
• Percutaneous nephrostomy ? if the kidney is obstructed and infected, drainage takes priority over stone fragmentation.
• Ureteroscopy for steinstrasse ? if a column of fragments blocks the ureter after ESWL.
• Stone analysis and metabolic workup ? arranged after fragments are collected, to guide prevention.

Preparation and Recovery

Preparation for ESWL Surgery

• Consultation: Discuss your full medical history and every medicine you take, including Ayurvedic or herbal preparations and over-the-counter painkillers.
• Pre-procedure instructions: Follow the dietary and medication instructions given, including fasting times.
• Hydration: Stay well hydrated in the days before the procedure, unless your doctor has restricted fluids for a heart or kidney reason.
• Practical points: Arrange a companion to accompany you home, as sedation makes driving unsafe. Wear loose clothing and remove metal jewellery.

Recovery After ESWL Surgery

• Rest: Take it easy and avoid strenuous activity for a few days.
• Hydration: Drink plenty of fluids to help flush out fragments ? typically 2.5?3 litres a day unless restricted.
• Pain management: Mild pain is common as fragments pass. Use only the analgesics your doctor advises; avoid unsupervised NSAID use if kidney function is reduced.
• Follow-up: Attend all review appointments and imaging so that clearance can be confirmed and any residual fragment treated.
• Expected findings: Blood in the urine for a day or two, mild bruising over the flank, and intermittent colicky pain are usual. Fever, inability to pass urine, or severe unrelenting pain are not.

Phase-by-Phase Recovery Timeline

Returning to Work, Driving and Sport

• Desk or office work: usually 2?3 days.
• Physically demanding work, farming, construction: generally 1?2 weeks, and longer if a stent is in place.
• Driving a car: once sedation has fully worn off and pain does not distract you, often after 48 hours.
• Two-wheeler travel on rough roads: better delayed for about a week, as vibration worsens flank discomfort and stent irritation.
• Gym, running, swimming: typically after 2?3 weeks, when pain and haematuria have settled.
• Contact sport, kabaddi, cricket, gym weight training: only after the urologist confirms no significant residual fragment or haematoma.
• Indian-specific: squatting for an Indian-style toilet, sitting cross-legged on the floor, and floor sleeping are all acceptable after ESWL, since there is no wound. They may simply feel uncomfortable while a stent is in place; use a Western toilet or a raised stool if squatting brings on pain.

Preventing Recurrence

Stone recurrence is common ? a substantial proportion of stone formers develop another stone within five to ten years. Uttar Pradesh lies within India's stone belt, where heat, sweating and low fluid intake add to the risk. Practical prevention includes:

• Fluids: aim for at least 2.5 litres of urine output a day ? roughly 3 litres of intake, more in summer or for outdoor workers.
• Salt: reduce papad, pickle, packaged namkeen, chips and added table salt; high sodium raises urinary calcium.
• Animal protein: moderate red meat and organ meats, which raise uric acid and lower urinary citrate.
• Oxalate: for calcium oxalate formers, moderate spinach, beetroot, chocolate, nuts, strong tea and soya ? moderation, not elimination.
• Calcium: do not cut dietary calcium such as milk, curd and paneer; normal calcium intake actually reduces stone risk. Calcium supplements should be taken only if prescribed.
• Citrate: lemon or nimbu water and, where indicated, potassium citrate therapy.
• Metabolic evaluation: recommended for recurrent stone formers, children, single-kidney patients and those with a strong family history.
• Surveillance: yearly ultrasound KUB for known stone formers, even without symptoms.

Children and Older Patients

Children

ESWL is often the preferred first choice in children because their ureters clear fragments efficiently and stone burden is usually small. General anaesthesia is commonly used to keep the child still and to protect the targeting, and lower energy settings with lung shielding are used. Every child with a stone should have a metabolic evaluation, since an underlying metabolic or genetic cause is more likely than in adults.

Older adults

Age itself is not a barrier. What matters is control of diabetes and blood pressure, kidney function, and management of anticoagulants and antiplatelets, which usually need a pause coordinated with a cardiologist or physician. Older patients may clear fragments more slowly and are more likely to need a stent. Cardiac pacemakers and implanted defibrillators are not an absolute contraindication, but require prior cardiology assessment and device checks.

If You Choose Not to Have the Procedure

Declining treatment is a legitimate choice for a small, non-obstructing, asymptomatic calyceal stone, provided you agree to periodic imaging. For a stone that is obstructing, growing, infected, or causing repeated pain, the likely course without treatment includes:

• Recurrent episodes of renal colic and lost working days.
• Progressive hydronephrosis and, over months, silent loss of function in that kidney.
• Increasing stone size and hardness, so that a stone once treatable by ESWL later needs RIRS or PCNL.
• Risk of infected obstruction and sepsis, which is a life-threatening emergency.

If you decide to wait, ask for a written surveillance plan and clear instructions on the symptoms that mean you should come in immediately.

Factors That Affect the Cost of ESWL

We do not publish figures here, because the final estimate depends on your clinical situation. Please ask the Apollo Hospitals Lucknow reception or billing desk for a written estimate for your case.

Insurance, Cashless Treatment and TPA Process in India

• Coverage: ESWL is generally covered by Indian health insurance as a day-care procedure ? most insurers list lithotripsy among their day-care procedures, so a 24-hour admission is not always required. Confirm the wording of your own policy.
• Waiting periods: many policies apply a 30-day initial waiting period and a specific waiting period of 1?2 years for urinary stone disease. If your stone was diagnosed before the policy started, it may be treated as a pre-existing condition with a longer wait.
• Planned versus accident cover: ESWL is a planned admission, so pre-authorisation should be applied for 3?7 days in advance. Accident-related and emergency admissions follow a different, faster route.
• Cashless steps: share your e-card and photo ID at the insurance desk, the hospital sends the pre-authorisation request to the TPA or insurer, approval usually arrives within a few hours to two working days, and any non-payable items are settled at discharge.
• Non-payable items typically include consumables, registration, admission kits and dietary extras.
• Reimbursement: if cashless is declined or you prefer to pay first, keep the discharge summary, itemised bill, receipts, investigation reports and imaging films, and file within your insurer's deadline.
• Government and corporate schemes: eligibility under CGHS, ECHS, state schemes or corporate panels varies by hospital empanelment. Please verify current empanelment status directly with the Apollo Hospitals Lucknow insurance desk before admission.

Planning Your Visit and What to Bring

• All previous reports: ultrasound, X-ray KUB, CT KUB films and CDs, urine culture, blood tests, and any earlier stone analysis or discharge summaries.
• A written list of current medicines, with doses ? including blood thinners, diabetes medicines and blood pressure tablets.
• Photo ID, insurance card, TPA details and the policy document.
• Loose clothing, slippers, a water bottle, and a small towel.
• A strainer or fine mesh if you have been asked to collect fragments for analysis.
• One attendant. In joint families it helps to nominate a single point person for consent, billing and doctor communication, so that instructions are not lost between relatives.
• Come fasting as instructed, and confirm the reporting time the previous day.

Warning Signs That Need Urgent Review

• Fever above 38?C (100.4?F), especially with chills or rigors.
• Pain that does not settle with prescribed painkillers, or that keeps worsening.
• Inability to pass urine, or passing very little urine.
• Heavy, persistent bleeding or blood clots in urine beyond two or three days.
• Repeated vomiting preventing fluid intake.
• Fainting, breathlessness, very low blood pressure or confusion ? go to Emergency immediately.
• With a stent in place: severe flank pain on passing urine, or a stent removal date that has passed. A forgotten stent can encrust and cause serious damage.

For Patients Travelling From Nearby Districts

Apollo Hospitals Lucknow receives stone patients from across central and eastern Uttar Pradesh and neighbouring states, including Kanpur, Unnao, Barabanki, Sitapur, Hardoi, Rae Bareli, Sultanpur, Ayodhya (Faizabad), Gonda, Bahraich, Basti, Gorakhpur, Pratapgarh, Jaunpur, Varanasi, Prayagraj, Bareilly and parts of Bihar and Nepal.

• Send reports ahead by email or WhatsApp so the team can advise whether ESWL is even likely to be suitable before you travel.
• Combine the visit: consultation, blood tests and CT KUB can often be done on the same day, with the procedure scheduled for the next morning.
• Plan 2?3 days in Lucknow for a single session, and remember that repeat sessions are usually 1?2 weeks apart ? factor this into travel planning.
• Follow-up: the first review can sometimes be handled by teleconsultation with imaging done locally, but stent removal must be done in person.
• Travel comfort: after ESWL, long bus or train journeys on the same day are best avoided; if unavoidable, carry prescribed analgesics, water and a strainer.
• Guest-house and accommodation options near the hospital can be discussed with the front desk at the time of booking.

Frequently Asked Questions

What is ESWL Surgery, and how does it work?

ESWL, or Extracorporeal Shock Wave Lithotripsy, is a non-invasive procedure that uses focused shock waves generated outside the body to break kidney stones into smaller fragments. These fragments then pass out through the urinary tract in the urine over the following days to weeks. At Apollo Hospitals Lucknow, imaging is used to target the stone precisely throughout the session.

What are the risks associated with ESWL Surgery?

ESWL is generally safe, but possible effects include blood in the urine, flank bruising, colicky pain as fragments pass, infection, and occasionally a perirenal haematoma. Sometimes the stone does not fragment fully and another session or an endoscopic procedure is needed. Your urologist will discuss these risks with you before you consent.

How long does the ESWL procedure take?

The session itself usually takes about 45 minutes to an hour. Total time in hospital is longer ? commonly four to six hours ? because of registration, preparation and post-procedure observation.

When can I return to normal activities after ESWL Surgery?

Most people resume routine activities within a few days. Strenuous activity and heavy lifting are best avoided for about a week, or longer if a stent is in place. Your team will give you guidance based on your stone and your work.

How do I schedule a consultation for ESWL Surgery at Apollo Hospitals Lucknow?

You can book online through the official Apollo Hospitals Lucknow website or the Apollo 24|7 app, or call the helpline number listed on the official site. Walk-in registration at the OPD reception is also possible.

How many ESWL sessions will I need?

Many small stones clear after one session, but larger or harder stones often need two or three. The exact number cannot be predicted in advance, which is why we reassess with imaging after each sitting. Most guidelines suggest reconsidering the plan if there is no meaningful progress after about three sessions.

Is ESWL painful?

You will feel repetitive tapping or thumping over the flank, which most adults tolerate with sedation and painkillers. The more uncomfortable part is usually the colicky pain over the next few days as fragments move down the ureter. Children are usually given general anaesthesia.

Will I definitely become stone-free after ESWL?

No procedure can guarantee that. Reported stone-free rates vary widely ? better for small, soft, well-positioned stones and poorer for large, hard or lower-pole stones. Some patients have small residual fragments that need follow-up or further treatment.

Do I need a DJ stent with ESWL?

Not always. Stents are usually placed for larger stones, a solitary kidney, existing obstruction, or if you have had an episode of infection. A stent protects drainage but often causes urinary urgency, burning and flank discomfort, which settle once it is removed.

Can ESWL be done if I have diabetes or high blood pressure?

Yes, provided both are reasonably controlled. Uncontrolled hypertension increases the risk of bleeding around the kidney, so blood pressure is checked and optimised before the procedure. Bring your current prescriptions to the pre-procedure consultation.

I take blood thinners for my heart. Can I still have ESWL?

Antiplatelet and anticoagulant medicines usually need to be stopped for a defined period before ESWL because of bleeding risk. This must be planned jointly by your urologist and your cardiologist or physician ? never stop these medicines on your own. If they cannot safely be stopped, ureteroscopy may be a better option.

Can ESWL be done during pregnancy?

No. Pregnancy is an absolute contraindication for ESWL.
