Before undergoing Retrograde Intrarenal Surgery (RIRS) in Kolkata, several diagnostic tests are typically conducted to assess the patient's condition and ensure the suitability of the procedure. These tests aid in providing a comprehensive evaluation of the patient's kidney health and identifying any underlying issues. The following are the commonly employed diagnostic tests before RIRS;

• X-Rays: X-rays are a standard imaging modality that can provide valuable information about the structure and overall health of the kidneys. They help in identifying the presence of kidney stones, abnormal calcifications, or other structural abnormalities that may require further investigation.
• Abdominal Ultrasound: Abdominal ultrasound is a non-invasive imaging technique that utilizes high-frequency sound waves to produce real-time images of the abdominal organs, including the kidneys. It helps in visualizing the size, shape, and structure of the kidneys, identifying any signs of obstruction, tumors, or cysts.
• Magnetic Resonance Imaging (MRI): Magnetic Resonance Imaging (MRI) is a sophisticated imaging modality that utilizes a powerful magnetic field and radio waves to generate detailed cross-sectional images of the kidneys. MRI provides excellent visualization of the renal anatomy and can detect abnormalities such as tumors, cysts, or congenital malformations.
• Blood Test: Blood tests, including a comprehensive metabolic panel, are routinely performed to assess kidney function. These tests evaluate various parameters such as serum creatinine, blood urea nitrogen (BUN), and electrolyte levels. Abnormal results may indicate underlying kidney disease or impaired renal function.
• Urinalysis: Urinalysis involves examining a urine sample to assess its composition and detect any abnormalities. It helps identify the presence of blood, infection, or abnormal levels of substances such as protein or crystals. Urinalysis provides valuable insights into kidney health and can aid in the diagnosis of conditions that may require RIRS.

RIRS (Retrograde Intrarenal Surgery) is a surgical procedure commonly performed under general anesthesia to ensure patient comfort and minimize renal mobility during breathing. It is an effective treatment option for kidney stones smaller than 2 cm and cases where shock wave lithotripsy (SWL) has been unsuccessful. The procedure typically lasts between 60 to 90 minutes, and patients usually require a one-day stay at the hospital. RIRS offers advantages over regular surgery, including a shorter recovery period and reduced risks. Here is a detailed overview of how RIRS is performed;

• Step 1: Anesthesia - The first step in RIRS surgery is the administration of anesthesia to the patient. Depending on the patient's medical history and overall health, either general anesthesia or spinal anesthesia is used to ensure their comfort and safety throughout the procedure.
• Step 2: Insertion of the Endoscope - Once the patient is anesthetized, a urologist inserts a small, flexible endoscope through the urethra, bladder, and into the ureter. The endoscope is equipped with a small camera that provides a clear view of the kidney and any stones present. The urologist carefully navigates the endoscope to reach the affected area.
• Step 3: Breaking Up the Kidney Stones - With the endoscope in place, the urologist employs specialized equipment such as a laser or ultrasound to fragment the kidney stones into smaller, more manageable pieces. This process is known as lithotripsy. The energy from the laser or ultrasound breaks down the stones without causing harm to the surrounding tissues.
• Step 4: Removing the Stones - Once the kidney stones have been fragmented, the urologist utilizes a small basket attached to the endoscope to retrieve the stone fragments. The basket securely grasps the stone pieces, allowing for their safe removal from the kidney. These stone fragments are sent to a laboratory for analysis to determine their composition, which aids in guiding future preventive measures.
• Step 5: Post-operation Procedure - After the completion of the RIRS procedure, the patient is closely monitored for any potential complications. Pain medication is administered as needed to manage post-operative discomfort. Most patients are able to return home on the same day and typically resume their regular routines within a few days. It is crucial for patients to follow the post-operative care instructions provided by their urologist to ensure a smooth recovery and optimal outcomes.

Retrograde intrarenal surgery (RIRS) is an advanced procedure utilized in Kolkata for the removal of kidney stones, even those as large as 14mm. This innovative technique enables the treatment of stones that may be lodged in the upper calyx, middle calyx, lower calyx, ureter, or urinary bladder, all without the need for any cuts or incisions. Renal stone removal through RIRS involves the use of a ureteroscope, a sophisticated instrument that allows for precise visualization and intervention within the kidney. RIRS has gained popularity as an effective method for managing challenging kidney stones that have shown resistance to shockwave lithotripsy and ureteroscopy.

Retrograde intrarenal surgery (RIRS) is a highly advanced and safe procedure used for the management of kidney stones in Kolkata. While RIRS is generally well-tolerated and associated with minimal side effects, it is essential to discuss potential complications with patients to ensure their complete understanding. It is important to note that the occurrence of side effects is extremely rare and limited to a very small number of cases. The following are some of the potential side effects that have been reported in a few patients who underwent RIRS;

• Fever: In rare instances, patients may experience a mild increase in body temperature following RIRS. This can usually be managed with appropriate medication and resolves without any significant consequences.
• Urinary Tract Infection: As with any surgical procedure involving the urinary system, there is a remote possibility of developing a urinary tract infection. However, strict adherence to sterile techniques and the use of prophylactic antibiotics help minimize the risk of infection.
• Momentary Haematuria: Temporary blood in the urine, known as haematuria, may occur after RIRS. This is usually self-limiting and resolves spontaneously without intervention. It is important to note that significant bleeding is rare.
• Acute Urinary Incontinence: In rare cases, patients may experience a temporary loss of urinary control following RIRS. This is typically transient and resolves as the body recovers from the procedure.
• Ureter Avulsion: Although extremely uncommon, there have been isolated reports of ureter avulsion during RIRS. This refers to a rare occurrence where the ureter becomes detached from the kidney or bladder. Such cases require immediate surgical intervention to address the complication.
• Bleeding: While bleeding is uncommon, it can occur during or after RIRS. The surgeon takes every precaution to minimize bleeding during the procedure, and any bleeding that does occur can usually be managed effectively.
• Sepsis: Sepsis, a severe infection that can affect the whole body, is an extremely rare but potentially serious complication. The risk of sepsis is minimized through stringent sterile techniques, the use of antibiotics, and close post-operative monitoring.

Recovery after RIRS (Retrograde intrarenal surgery) in Kolkata is an important phase that allows patients to heal and regain their normal activities. The duration of recovery typically ranges from 24 to 48 hours, followed by a period of complete rest. It is crucial for patients to maintain adequate fluid intake to ensure urine production and facilitate the healing process. The doctor's instructions regarding medications and lifestyle modifications must be strictly followed to optimize recovery.

• Rest and Activity: Upon returning home, it is essential to prioritize rest. Sitting may be uncomfortable for a few days, so it is advisable to find a comfortable position. Gradually increase activity levels, avoiding strenuous activities while the urine still appears bloody.
• Pain Management: Patients may experience discomfort while passing small stone fragments and a stinging sensation during urination for a few days. The urologist may recommend a non-steroidal anti-inflammatory medication (NSAID) such as ibuprofen or diclofenac to alleviate pain and reduce inflammation.
• Fluid Intake: It is crucial to maintain a sufficient fluid intake to keep urine light in color. Drinking ample water (8-10 liters per day) helps in flushing out stone fragments and promotes overall healing.
• Dietary Considerations: Following a nutritious diet is important during the recovery phase. The diet should include foods high in fiber to promote healthy bowel movements. It is advisable to reduce the consumption of foods that contribute to constipation and excessive straining. In some cases, the doctor may recommend a mild laxative for a few days to alleviate constipation.
• Fluid Restrictions: It is recommended to reduce the intake of alcohol and caffeinated beverages during the recovery period. Patients with other medical conditions should consult their doctor regarding appropriate fluid intake.
• Bathing and Pain Relief: Taking a hot bath can provide relief, while stronger pain relievers may be prescribed if the discomfort is more severe. Medications may also be prescribed to facilitate the passage of stone fragments.
• Antibiotics and Urine Analysis: To prevent or treat any urinary tract infection, the doctor may prescribe antibiotics. It is important to take antibiotics as prescribed. Additionally, patients may be instructed to strain their urine to detect small stone fragments, which can be saved for analysis to guide future treatment decisions.
• Follow-up and Stent Removal: It is crucial to follow the surgeon's recommendations regarding time off work. During the initial follow-up visit, the doctor may remove a temporary ureteral stent if one was inserted. Stent removal can be done through two methods: pulling on a string attached to the stent or performing a cystoscopy to remove a stent without a string.
