Pyelolithotomy Surgery

Pyelolithotomy surgery

Pyelolithotomy refers to an operation to take out kidney stones (renal calculi) in the renal pelvis- the funnelled region where urine gathers and enters the ureter.

It is usually performed when:

• Rocks are too broad to be removed by means of minimally invasive techniques (PCNL, ureteroscopy).
• An abnormality of the anatomy of the stones is affected.
• Minimal intervention procedures have not worked.
• Big, branching (staghorn) stones present however PCNL is not possible.

This may be accomplished through open-surgical operation, laparoscopy or robot-assisted operation.

Pyelolithotomy Surgery Procedure

Anaesthesia

• General anaesthesia is administered to the patient.

Positioning

• Patient is positioned in a lateral flank.

Incision

• Pyelolithotomy is done through the open method (open pyelolithotomy).This involves an incision in the flank to expose the kidney.
• Laparoscopic / robotic: Small incisions are made. 

Exposure of Kidney

• The kidney is reached by separating the muscles.
• The pelvis of the kidneys is recognized.

Renal Pelvis (Pyelotomy) opening

• Longitudinal incision is done on the renal pelvis.

Stone Removal

• The forceps are used to remove one or several stones.
• Stone fragments are swept off to make sure that they are all removed.

Inspection

• A scanned scope could be transferred in order to detect remaining stones.

Closure

• The renal pelvis is sutured.
• A drain may be placed.
• Incisions are sewn up in layers.

Duration

• Typically 1.5 to 3 hours, according to difficulty and size of rock.

Open pyelolithotomy procedure

Open pyelolithotomy refers to a surgical procedure that is used to extract kidney stones out of the renal pelvis using a classical open incision.

It is usually selected when:

• Stones are large or impacted
• PCNL or ureteroscopy cannot be done or has been done.
• Anatomical defects do not allow least invasive access.
• Stones that are multiple or complicated need to be open.

Preoperative Preparation

• Regular blood analysis, urine analysis, and x-rays (CT/ KUB ultrasound).
• IV antibiotics started.
• Patient is kept fasting.
• General anaesthesia is provided.

Patient Positioning

• The patient was in a flank (lateral) position with the affected side of kidneys facing up.
• Table can be bent to increase the rib and pelvis spacing.

Skin Incision

An incision with a flank is made, either:

• Oblique (subcostal) incision, or
• Incision in the 12th rib to access the retroperitoneal space.
• Incision is normally 8-12 cm long.

Exposure of the Layer by Layer

• Skin, subcutaneous adipose tissue and musculature (latissimus, external oblique internal oblique) are distinguished. 
• This is done by entering retroperitoneal space without opening peritoneum.
• To uncover the kidney, Gerota’s fascia is incised.

Mobilization of the Kidney

• A gentle mobilization of the kidney is carried out to reveal the renal pelvis.
• Extreme precaution is observed to maintain renal vessels and adjacent structures.
• In case of necessity, a vascular clamp can be used in the short term to minimize bleeding.

Renal Pelvis Identification

• The pelvis of the kidney is seen and separated.
• The palpation or ultrasound guidance (where possible) confirms stone location.

Pyelotomy (Pelvic Opening of the Renal Nerve)

• On the renal pelvis, a longitudinal incision is done.
• The dimensions are sufficient enough to remove the stones.

Stone Extraction

• Stone forceps are used to pull out a rock or rocks.
• Pieces of stone are carefully picked.
• Surgeon either by hand or using a flexible nephroscope and verifies that every stone has been cleared.

Irrigation and Inspection

• Saline is used to flush the renal pelvis to clear the debris.
• Any bleeding point is contained.

Closure of Renal Pelvis

• Absorbable sutures are used to repair the pyelotomy incision.
• A ureteral stent (Double-J stent) can be turned to guarantee drainage and avoid leakage.

Drain Placement

• A surgical drain (tube drain /Jackson-Pratt drain) placed around the kidney if it leaked urine or blood.

Wound Closure 

• The sequential closing of muscle layers, subcutaneous tissue and skin takes place.
• A dressing is applied.

Duration

• The surgery usually lasts between 1.5 and 3 hours, depending on the size of the stones and the anatomy.

Noteworthy Advantages of Open Pyelolithotomy 

• Removal of stones.
• Applied where anatomy is distorted or scarring has been done by prior surgeries.
• Suitable when using very large or complicated stones.

Pyelolithotomy recovery

The recovery after pyelolithotomy (open, laparoscopic, or robotic) is different according to the surgical method, the size of the stones, the patient health condition, and the existence of a stent or a drain.

In general, the majority of patients heal in an easy way with rest and follow-up.

Hospital Stay

Open Pyelolithotomy

• 2–5 days of hospitalization
• Takes a longer time in the monitoring because of the bigger incision.

Laparoscopic/Robotic Pyelolithotomy

• 1–3 days stay
• Fewer pain and faster recovery.

Pain & Medication

• The area that is supposed to develop pain is incision/ flank within a few days.
• Anti-nausea, antibiotic and pain reliever drugs are administered.
• Post-discharge pain of minor levels can persist up to 1-2 weeks (open surgery more).

Drain & Catheter Care

• The surgery drain (when inserted) is normally taken out 24-48 hours after its output decreases.
• Foley catheter is discharged after 1-2 days.
• Ureteral stent (DJ stent) can be left to last 2-4 weeks so that the urine flows smoothly.

Activity & Mobility

Day 1

• Slow walking is advised to the patients.
• Helps in reducing the formation of clots and enhances the functioning of the kidneys.

First Week

• Light activities only.
• Avoid lifting >3–5 kg.
• The laparoscopy patients will feel improved sooner, the open surgery patients have to rest more.

Return to Normal Activities

• Laparoscopic/robotic: 2–3 weeks
• Open surgery: 4–6 weeks
• Heavy work: 6–8 weeks

Diet After Surgery

• Begin with liquids and proceed to soft diet and then regular diet.
• Take 2-3 liters of water per day as long as it is not limited.
• They should avoid high amounts of salt and protein to avoid forming new stones.

Wound Care

• The incision should be kept clean and dry.
• In case they are not absorbable, stitches or staples are removed in 7-10 days.

Follow-Up Tests

Doctors typically order:

• To ensure clearance of stones, ultrasound or X-ray/CT scan.
• Urine tests for infection
• Function tests (creatinine, urea) of the kidneys.
• Removal of the stent is typically after 2-4 weeks.

Long-Term Care

To prevent stone recurrence:

• Maintain good hydration
• Minimize salty and high oxalate foods.
• The amount of calcium taken must be moderate (not too much).
• Frequent follow up after every 6-12 months.
• Recurrent stone formers by metabolic evaluation.

Expected Full Recovery

• Laparoscopic/robotic: ~3–4 weeks
• Open pyelolithotomy: ~6–8 weeks
• The renal functioning will resume normalcy with reference to pre-surgical position.

Pyelolithotomy complications

Pyelolithotomy has relatively few complications, but it may also be complicated particularly in open surgeries. A majority of them can be treated through early healthcare.

Immediate (Intraoperative) Complications

• Bleeding
• Injury to Nearby Structures
• Conversion

Complications in the early postoperative period 

• Urine Leakage
• Infection
• Postoperative Pain
• Hematuria
• Respiratory Problems

Intermediate Complications (First Few Weeks)

• Wound Issues
• Stent-Related Symptoms
• Prolonged Drain Output

Late Complications

• Ureteropelvic Junction Stricture

Conclusion

Pyelolithotomy continues to be a valuable and dependable surgical method for the extraction of large, impacted, or anatomically difficult stones within the kidney when minimally invasive methods such as PCNL or ureteroscopy are infeasible. The procedure provides direct access to the renal pelvis, enabling complete stone removal, whether it is done through an open, laparoscopic, or robotic technique. With the development of surgery, the majority of patients have a good result, although a surgical approach is associated with variable rates of recovery and complications. Prevention measures and close postoperative follow-up are important for preventing recurrence and maintaining long-term renal function.

FAQ

1. Which is more effective, open or laparoscopic pyelolithotomy?

• Laparoscopic: reduced pain, quicker recovery, less scarring 
• Open: More suitable for complicated anatomy, previous surgeries, or extremely large stones

The choice depends on the size of the stone, the special condition of the patient, and the experience of the surgeon. 

2. Does pyelolithotomy leave a scar?

• Open surgery: Yes, a flank incision is visible
• Laparoscopic/robotic: Small scars on the site of the ports

3. Will I need a stent?

• Often yes. A Double-J (DJ) stent placement is a common procedure to facilitate proper urine flow, and minimize the possibility of urine leakage. It stays for 2–4 weeks.

4. Will the stone come back after surgery?

• Stones can come back if you have the same underlying metabolic problems. Drinking water, making dietary changes, and having regular kidney exams will help mitigate risk of recurrence.

5. Is pyelolithotomy painful?

• Open surgery is associated with more pain in the postoperative period than laparoscopic surgery. Pain can be well controlled with medications.

6. Is pyelolithotomy safe?

• Yes. It's generally safe in the hands of experienced urologists. There has been a dramatic reduction in the risk for complications with current techniques.
