WHAT IS PELVIC LYMPH NODE DISSECTION (PLND)?
- Pelvik lenf nodu diseksiyonu (PLND), kas invaziv mesane kanseri cerrahisinin standart bir parçası olup hastalığın doğru evrelenmesi ve mikroskobik metastazların temizlenmesi için kritik öneme sahiptir.
- 2026 EAU kılavuzlarına göre radikal sistektomi sırasında her iki taraflı lenf nodu çıkarılması, tedavi planlamasını optimize eder ve seçilmiş hastalarda sağkalım oranlarını artırabilir.
- Cerrahi sırasında lenf nodlarının anatomik sınırlara uygun şekilde titizlikle temizlenmesi, ameliyat sonrası kemoterapi gibi ek tedavi kararlarının verilmesine rehberlik eder.

Pelvic Lymph Node Dissection (PLND) and Its Role in Bladder Cancer Treatment
Pelvic lymph node dissection (PLND) is a critical surgical procedure performed during radical cystectomy to remove the lymph nodes surrounding the bladder. The primary goals of this procedure are to determine if bladder cancer has spread to the lymphatic system, provide accurate pathological staging, and potentially improve oncological outcomes in appropriately selected patients.
According to the 2026 European Association of Urology (EAU) Guidelines, bilateral pelvic lymph node dissection is an essential component of standard radical cystectomy for Muscle-Invasive Bladder Cancer (MIBC). This procedure ensures a comprehensive approach to managing advanced bladder cancer cases.
What is Pelvic Lymph Node Dissection?
Pelvic lymph node dissection involves the surgical removal of specific lymph nodes located within the pelvis during a radical cystectomy. This procedure is not merely diagnostic; it provides a definitive pathological assessment of the disease's extent.
By removing these nodes, surgeons can identify microscopic lymph node metastases that current imaging techniques, such as CT or MRI, might not detect. This level of precision is vital for determining the next steps in a patient's treatment journey.
Why Are Lymph Nodes Removed During Surgery?
The pelvic lymph nodes are typically among the first locations where bladder cancer cells migrate. Removing them is a strategic step in cancer management for several reasons:
- Accurate Staging: It helps determine the true stage of the disease.
- Pathological Assessment: Provides detailed information for the medical team.
- Treatment Guidance: Helps guide postoperative treatment decisions, such as chemotherapy.
- Oncological Outcomes: Potentially improves long-term survival in selected patients.
Who Requires Pelvic Lymph Node Dissection (PLND)?
Based on the 2026 EAU Guidelines, PLND is considered an essential part of standard surgical management. It is specifically indicated for:
- Patients undergoing radical cystectomy for Muscle-Invasive Bladder Cancer (MIBC).
- Selected patients with very high-risk bladder cancer when radical cystectomy is required.
What Happens During the Operation?
During a radical cystectomy, the surgeon carefully removes lymph nodes on both sides of the pelvis within standardized anatomical boundaries. This meticulous process ensures that all potentially affected tissues are addressed.
Once removed, the lymph nodes are sent to specialized pathologists. These experts examine the tissue under a microscope to confirm the presence or absence of cancer cells, which is crucial for the final diagnosis.
The Benefits and Risks of PLND
Benefits of the Procedure
Implementing PLND during surgery offers significant clinical advantages:
| Benefit | Description |
|---|---|
| Precise Staging | Offers the most accurate pathological staging available. |
| Optimized Planning | Enables better postoperative treatment and follow-up planning. |
| Metastasis Removal | Eliminates microscopic metastases that imaging might miss. |
| Improved Survival | Contributes to better long-term cancer outcomes in specific patient groups. |
Potential Risks and Complications
As with any major surgical intervention, there are potential risks involved. However, when performed by experienced surgical teams, the risk of serious complications remains low. Possible issues include:
- Bleeding
- Lymphatic leakage
- Lymphocele formation
- Rare injury to nearby blood vessels or nerves
EAU 2026 Key Message for Patients
The 2026 European Association of Urology (EAU) Guidelines emphasize that bilateral pelvic lymph node dissection within appropriate anatomical templates should be performed during radical cystectomy whenever indicated. Seeking treatment in experienced, high-volume centers is vital for achieving optimal surgical quality and the best possible patient outcomes.

Conclusion
In summary, pelvic lymph node dissection is an integral component of radical cystectomy for Muscle-Invasive Bladder Cancer. Through accurate staging and the removal of microscopic metastatic disease, PLND plays a decisive role in improving long-term oncological outcomes and guiding individualized postoperative care.
Frequently Asked Questions (FAQ)
Does removing lymph nodes mean the cancer has already spread?
No. Lymph nodes are removed for two main reasons: to achieve accurate staging and to treat potential microscopic metastatic disease that is not yet visible on scans.
Does every patient undergoing radical cystectomy need PLND?
In the majority of cases involving Muscle-Invasive Bladder Cancer, yes. Current international guidelines recommend bilateral pelvic lymph node dissection as a standard part of the surgical procedure.
Can radical cystectomy be performed without removing lymph nodes?
Except in very rare and carefully selected clinical situations, international guidelines define pelvic lymph node dissection as an essential and mandatory component of radical cystectomy.
