Retrograde Intrarenal Surgery (RIRS) at Apollo Hospitals, Lucknow

Why Patients Choose Apollo Hospitals Lucknow for RIRS

• A urology team built around stone disease: Apollo Hospitals Lucknow (Apollo Medics) runs a dedicated Urology and Andrology department where endourology procedures such as RIRS, ureteroscopy (URS), mini-PCNL and ESWL are performed as routine, planned work rather than occasional cases. The exact number of consultants on duty and their individual sub-specialty interests can be confirmed with the urology OPD desk at the time of booking.
• Apollo group legacy: Apollo Hospitals began in 1983 in Chennai and has grown into one of Asia's largest integrated healthcare groups, with more than 70 hospitals and over 10,000 beds across India. Clinical protocols, infection-control auditing and outcome tracking used in Lucknow follow group-wide standards.
• Flexible ureteroscopy with laser lithotripsy: RIRS at Apollo is performed with a flexible ureteroscope and a Holmium:YAG (or comparable) laser fibre, using fragmentation or dusting settings chosen according to stone size, density and location. Ureteral access sheaths, tipless baskets and stone-retrieval devices are used where clinically appropriate.
• Full imaging and diagnostic backbone under one roof: Non-contrast CT KUB, ultrasound KUB, digital X-ray, and a NABL-accredited laboratory for urine culture, renal function and metabolic stone workup ? so the surgical plan is based on current imaging, not old reports.
• 24x7 emergency and critical care support: Round-the-clock emergency services, intensive care units and blood bank access matter when a stone presents with obstruction and fever, which is a urological emergency needing urgent drainage rather than elective stone clearance.
• Care pathways for different age groups: Stone disease is managed differently in children, in adults of working age, in pregnant women, and in older patients with diabetes, hypertension or a single functioning kidney. Apollo Lucknow has in-house nephrology, endocrinology, cardiology, anaesthesia and paediatric services for pre-anaesthetic clearance and co-management.
• Recurrence prevention, not just stone removal: Roughly half of stone formers form another stone within five to ten years without preventive measures. Stone analysis, dietary counselling with a clinical dietitian, and metabolic evaluation for recurrent or high-risk formers are offered as part of follow-up.
• Support for out-of-town patients: Insurance and TPA desk assistance, cashless processing where the policy allows, and single-visit scheduling for patients travelling from districts around Lucknow.

Overview

Retrograde Intrarenal Surgery (RIRS) is a minimally invasive procedure designed to treat kidney stones and certain other conditions inside the kidney. At Apollo Hospitals Lucknow, urological care is delivered using current endourological technology and established surgical techniques. The team works towards personalised treatment plans built around each patient's stone burden, kidney anatomy, kidney function and general health. The focus is on informed decision-making, safety and realistic expectations rather than promises of guaranteed outcomes.

In RIRS, no cut is made on the body. A thin flexible telescope is passed through the natural urinary passage ? urethra, bladder, ureter ? up into the kidney's collecting system. Stones are then broken with a laser and either removed or left to pass as fine fragments.

Why Retrograde Intrarenal Surgery (RIRS) is Necessary

RIRS is an important option for patients with kidney stones that are too large to pass on their own or that are causing significant pain and discomfort. The procedure allows direct treatment of stones in the renal pelvis and calyces using a flexible ureteroscope introduced through the urinary tract. Its main advantages include:

• Minimally invasive: Unlike traditional open surgery, RIRS needs no large incisions, which generally means less pain and a quicker return to routine.
• Effective stone removal: RIRS can treat stones of varying sizes and compositions, and most patients get relief from symptoms. Very large or very hard stones may need more than one session.
• Preservation of kidney function: Because the stone is targeted directly, damage to surrounding kidney tissue is kept to a minimum, helping preserve overall kidney function.

At Apollo Hospitals Lucknow, the urology team uses current equipment and techniques with the aim of maintaining a high standard of care during RIRS.

Risks of Delay

Delaying RIRS when it has been advised can lead to serious complications. Kidney stones can cause severe pain, urinary tract infections, and kidney damage if left untreated. The longer treatment is postponed, the higher the risk of:

• Infection: Untreated stones can lead to urinary tract infections, which may need additional treatment. An infected, obstructed kidney can become life-threatening and requires urgent drainage.
• Kidney damage: Prolonged obstruction from a stone can cause irreversible loss of kidney function, and in some cases contributes to chronic kidney disease.
• Increased pain: As stones enlarge, they can cause more intense pain and discomfort, significantly affecting quality of life. Larger stones are also generally harder to clear in a single session.

Timely intervention is emphasised at Apollo Hospitals Lucknow to reduce these risks and support better long-term kidney health.

Benefits of RIRS

• Quick recovery: Many patients return to normal activities within a few days, helped by the minimally invasive nature of the procedure.
• Reduced hospital stay: RIRS usually needs a shorter stay than traditional open surgery, and is often done as a day-care or single-overnight admission.
• Lower risk of some complications: Avoiding a skin incision and kidney puncture reduces the likelihood of significant bleeding and wound problems compared with open or percutaneous surgery.
• Improved quality of life: Effective stone clearance relieves pain and discomfort and reduces repeated emergency visits for colic.

Apollo Hospitals Lucknow aims to support patients through the entire pathway so that the best achievable outcome from RIRS is pursued in each case. Outcomes still vary with stone size, hardness, location and individual anatomy.

Preparation and Recovery

Preparation Tips

• Consultation: Book a detailed consultation with a urology specialist to discuss medical history, symptoms and concerns.
• Preoperative testing: Imaging and blood tests are usually needed to assess kidney function and the size and site of the stones.
• Medication review: Tell your doctor about every medicine you take. Blood thinners, antiplatelet drugs, some diabetes medicines and certain herbal supplements may need to be adjusted or stopped for a defined period before surgery ? never stop them on your own.
• Fasting: Follow the fasting instructions given, which typically means no food or drink for several hours before the procedure.

Recovery Tips

• Hydration: Drink plenty of fluids after surgery to help flush out remaining fragments and reduce the chance of new stones.
• Pain management: Take pain relief as advised. Do not self-medicate with high-dose NSAIDs if you have reduced kidney function.
• Activity level: Resume normal activity gradually, avoiding strenuous exercise and heavy lifting for a few weeks.
• Follow-up appointments: Attend all scheduled reviews so recovery can be monitored, the stent removed on time, and complications picked up early.

The team at Apollo Hospitals Lucknow supports patients through preparation and recovery with written instructions and a point of contact for questions.

What Current Guidelines Say

Stone management at Apollo Hospitals Lucknow is guided by Indian and international evidence-based recommendations, chiefly:

• Urological Society of India (USI) Clinical Practice Guidelines on Urolithiasis ? the Indian speciality reference for stone evaluation and management, developed by USI and published through the Indian Journal of Urology. USI guidance places particular weight on India's high stone-prevalence "stone belt", the need for pre-operative urine culture and treatment of infection before any endourological intervention, and the value of stone analysis and metabolic assessment in recurrent formers.
• European Association of Urology (EAU) Guidelines on Urolithiasis, 2024 edition ? widely used in Indian practice. Key points relevant to RIRS: for lower-pole and other renal stones up to about 20 mm, retrograde intrarenal surgery and shock wave lithotripsy are both reasonable first-line options, with RIRS generally giving higher single-session stone-free rates but requiring anaesthesia; for stones larger than about 20 mm, percutaneous nephrolithotomy (PCNL) remains first choice, with RIRS an alternative when PCNL is unsuitable or where staged flexible ureteroscopy is preferred.
• American Urological Association (AUA)/Endourological Society Surgical Management of Stones guideline (2016, amended 2019) ? supports ureteroscopy as a first-line option for most renal and ureteric stones and stresses that a urine culture should be obtained and infection treated before intervention.

Recommendations that have shifted in recent years:

• Routine stenting is no longer automatic. Guidelines now support omitting a ureteric stent after uncomplicated ureteroscopy in selected patients, because stents cause significant discomfort and urinary symptoms. Stenting is still advised where there is ureteric injury, residual fragments, infection risk, a solitary kidney, or a difficult procedure.
• Pre-stenting is selective, not standard. Placing a stent weeks before RIRS to passively dilate the ureter is reserved for cases where access fails or the ureter is too narrow, rather than done for everyone.
• Single-dose antibiotic prophylaxis is recommended for most cases, with longer courses reserved for proven infection or high-risk patients ? a change from older practice of prolonged post-operative antibiotics.
• Alpha-blockers (such as tamsulosin) for stent-related symptoms are now commonly used, with moderate evidence of benefit.
• Newer single-use (disposable) flexible ureteroscopes and suction-assisted access sheaths are increasingly available. Evidence suggests comparable results to reusable scopes; availability at any given hospital should be confirmed locally.

Guideline recommendations are general. Your urologist will explain how they apply to your stone, kidney and overall health.

Who is Suitable for RIRS, and Who is Not

Usually a good option

• Renal stones up to about 20 mm, particularly 10?20 mm.
• Lower-pole stones where shock wave lithotripsy has a lower clearance rate.
• Hard stones (such as calcium oxalate monohydrate or cystine) that resist shock wave lithotripsy.
• Stones in patients on long-term blood thinners or with bleeding tendencies, where PCNL carries higher risk.
• Obese patients, where percutaneous access and shock wave lithotripsy are technically harder.
• Patients with a single functioning kidney, abnormal kidney anatomy, horseshoe kidney or previous failed treatment.
• Upper ureteric stones that have migrated back into the kidney.

Usually needs a different approach or postponement

• Active, untreated urinary infection ? this must be treated first; drainage takes priority over stone clearance.
• Very large stone burden or complete staghorn stones ? PCNL is generally preferred.
• Uncorrected bleeding disorders, or a ureter that cannot be safely negotiated.
• Untreated bladder outlet or ureteric stricture that blocks scope passage.
• Pregnancy ? management is individualised; drainage or stenting is often preferred, and any endoscopic procedure needs joint urology?obstetric planning.

Timing of the Procedure and the Pre-Procedure Phase

RIRS is normally a planned procedure. What happens before the date matters as much as the surgery itself.

When a stone is causing fever with obstruction, anuria, or uncontrolled pain, the timing changes completely: urgent drainage with a DJ stent or percutaneous nephrostomy is done first, and definitive RIRS is scheduled once the infection has settled.

Alternatives and Technique Options Compared

The right choice depends on stone size, density on CT, location, kidney anatomy, infection status, previous treatments, body build, medicines you take, and your own preference after being told the trade-offs.

Procedures Sometimes Done at the Same Sitting

• DJ (ureteric) stent placement ? the most common addition, used to protect the ureter and ensure drainage.
• Ureteroscopic treatment of a ureteric stone in the same side, while the scope is already in place.
• Bilateral RIRS in selected fit patients with stones on both sides ? done only after careful assessment, as it increases operative time and risk.
• Ureteric stricture dilatation or endoscopic incision if a narrowing blocks access.
• Cystoscopic treatment of a bladder stone or removal of an old, encrusted stent.
• Biopsy or inspection of a suspicious upper-tract lesion if something abnormal is seen on ureteroscopy.
• TURP or bladder outlet procedure ? occasionally combined in older men with significant prostate obstruction, if the surgeon judges it safe in one sitting.

Anything additional is discussed and consented for in advance wherever it can be anticipated.

Phase-by-Phase Recovery Timeline

These are typical patterns, not guarantees. Recovery is slower after a difficult or prolonged procedure, in diabetes, in older patients and where infection was present.

Returning to Work, Exercise and Normal Life

General criteria before increasing activity

• Urine is clear or only faintly pink.
• Pain is controlled with simple oral medication.
• No fever for at least 48 hours.
• The stent, if placed, has been removed or is causing only minor symptoms.

Practical guidance

• Desk and office work: often 3?7 days.
• Driving a car: once off sedating painkillers and able to brake sharply without pain, usually 3?5 days.
• Two-wheeler riding: avoid for about 1?2 weeks and until the stent is out ? road vibration is a common trigger for pain and bleeding with a stent in place.
• Manual labour, farm work, loading, construction: usually 2?4 weeks, and generally after stent removal.
• Gym, weights, running, cycling: restart lightly after stent removal, building up over 1?2 weeks. Contact sports and heavy squats last.
• Long-distance travel: short trips are usually fine after a few days; if travelling with a stent, carry your discharge summary and know where the nearest urology service is.
• Sexual activity: usually after stent removal, or as advised; a stent can make intercourse uncomfortable.

India-specific everyday considerations

• Indian-style (squatting) toilets: deep squatting with a stent in place often triggers flank pain and a little bleeding. Use a Western commode for the first week or two if one is available, or a commode stool.
• Sitting cross-legged on the floor for meals or prayer is generally fine but may feel uncomfortable with a stent; sit on a low stool or against a wall support initially.
• Floor sleeping: acceptable, but getting up from the floor should be done by rolling to one side and using the hands rather than jerking up from the abdomen.
• Household chores: sweeping, mopping and washing clothes in a squatting position, and lifting water buckets, should wait until stent removal.
• Joint family caregiving: identify one family member as the main attendant. In practice, having a single person hold the discharge summary, medicine list and stent-removal date prevents missed appointments ? a common problem when responsibility is shared across many relatives.
• Fasting and religious observance: Karva Chauth, Navratri, Ramzan and similar fasts restrict fluids, which is the single worst thing for a recent stone patient. Discuss any planned fast with your doctor before committing to it.
• Summer heat and outdoor work: in Uttar Pradesh's summer, fluid losses are high. Outdoor workers need a deliberate drinking schedule rather than drinking only when thirsty.

Preventing Stone Recurrence

Stone disease is a recurring metabolic condition, not a one-time event. Without preventive measures, a substantial proportion of stone formers develop another stone within five to ten years. Uttar Pradesh lies within India's recognised stone belt, where hot climate and low fluid intake add to the risk.

Core measures for most patients

• Fluid intake: aim for a urine output of about 2?2.5 litres a day, which usually needs roughly 2.5?3 litres of fluid, more in summer or with physical work. Pale, straw-coloured urine is the practical marker.
• Salt: reduce added salt, pickles, papad, packaged namkeen, instant noodles and processed snacks. High sodium raises urinary calcium.
• Do not cut dietary calcium: normal dietary calcium (milk, curd, paneer) taken with meals actually lowers stone risk. Calcium supplements taken separately from food may increase risk ? check before starting them.
• Animal protein: keep red meat and organ meat moderate; very high animal protein raises uric acid and lowers urinary citrate.
• Oxalate-rich foods: relevant mainly for calcium oxalate formers ? spinach, beetroot, amaranth, sesame, nuts, excess tea. Moderation with meals rather than total avoidance is usually advised.
• Citrate: lemon or lime in water, and potassium citrate supplements when prescribed, help inhibit stone formation.
• Weight, diabetes and blood pressure control all reduce recurrence risk.
• Avoid unsupervised high-dose vitamin C or vitamin D supplements.

For recurrent or high-risk stone formers

• Send the retrieved stone for composition analysis ? this changes the prevention plan more than anything else.
• 24-hour urine studies for calcium, oxalate, citrate, uric acid, sodium and volume.
• Serum calcium, uric acid, parathyroid hormone and vitamin D where indicated.
• Targeted drug therapy, such as thiazides for high urinary calcium, potassium citrate for low citrate, allopurinol for uric acid stones, or alkalinisation for cystine and uric acid stones.
• Screening for underlying causes such as primary hyperparathyroidism, renal tubular acidosis, gout, inflammatory bowel disease or prior bariatric surgery.

Children, Older Adults and Special Situations

Children

• RIRS is technically feasible in children with appropriately sized flexible scopes, and is used when shock wave lithotripsy is unsuitable or has failed. Paediatric ureters are narrow, so pre-stenting is more often needed.
• Radiation exposure is minimised ? ultrasound is preferred for follow-up over repeated CT.
• Every child with a stone deserves a metabolic and, where relevant, genetic evaluation. Childhood stones far more often have an identifiable underlying cause, such as hypercalciuria, hyperoxaluria, cystinuria or a tubular disorder.
• Paediatric anaesthesia and paediatric nephrology involvement is routine.

Older adults

• RIRS is often the preferred option in older patients because it avoids incisions and is generally well tolerated even with cardiac or respiratory disease.
• Special attention is given to blood thinners, pacemakers, kidney function, drug doses, and delirium risk after anaesthesia.
• Coexisting prostate enlargement may need to be addressed, as poor bladder emptying worsens stent symptoms.
• Falls prevention matters at home ? a stent, urgency and night-time trips to the toilet are a common combination behind falls in elderly patients.

Other situations

• Single functioning kidney or transplant kidney: managed with extra caution; RIRS is often favoured to avoid parenchymal injury.
• Pregnancy: priority is relief of obstruction and treatment of infection; ureteroscopy in pregnancy is done only in selected cases with obstetric input, and radiation is avoided.
• Chronic kidney disease: contrast imaging and NSAIDs are used cautiously; nephrology co-management is usual.
• Diabetes: higher infection risk, so urine culture clearance and glycaemic control before surgery are important.
• Abnormal anatomy such as horseshoe kidney, pelvi-ureteric junction obstruction or calyceal diverticulum: RIRS may be harder, and success rates are lower; this should be discussed openly beforehand.

If You Choose Not to Have the Procedure

Declining or deferring surgery is a legitimate choice for some stones, and a risky one for others. What to expect:

• Small, non-obstructing, symptomless stones: active surveillance with periodic ultrasound is reasonable. Many stay stable for years; some grow or move and cause colic.
• Larger or obstructing stones left untreated: risk of repeated colic, emergency visits, recurrent urinary infection, hydronephrosis and gradual, often painless loss of function in that kidney. A silently obstructed kidney can be lost without any symptoms at all.
• Infection stones (struvite): these tend to grow steadily and are strongly associated with persistent infection; leaving them alone is generally not advised.
• Fever with an obstructed kidney can progress to sepsis within hours. This is not a situation where waiting is safe.

If you decide to wait, agree a definite surveillance plan with your urologist ? usually imaging and a kidney function check at set intervals ? rather than simply dropping out of follow-up. Return sooner if symptoms change.
