Why is this procedure recommended?

PCNL is recommended when stones are too large, too numerous, or too complex to be managed safely or effectively with less invasive treatments. It allows direct access to the kidney, enabling effective stone clearance in situations where other techniques may be inadequate.

This approach is particularly useful for patients with challenging anatomy or a high stone burden.

How is the procedure carried out?

The procedure is performed under general anaesthesia and involves a coordinated team approach.

• Imaging guidance is used to gain precise access to the kidney

• A small keyhole tract is created into the kidney drainage system

• Stones are fragmented and removed through this tract

• The procedure is carried out by a combined team of a urological surgeon, radiologist, and anaesthetist

Advanced variations of percutaneous stone surgery may be used depending on stone complexity and patient factors.

Anaesthesia, hospital stay & recovery

• Performed under general anaesthesia

• Patients are admitted to hospital for treatment

• Typical hospital stay is around three nights

• Recovery is monitored closely, with attention to kidney drainage and infection prevention

Specialist expertise & advanced techniques

PCNL forms part of advanced stone care for patients with complex stone disease. Specialist expertise allows the procedure to be adapted to individual anatomy and stone burden, including the use of modified percutaneous approaches where appropriate. This ensures effective stone clearance while minimising surgical trauma.

Follow-up & next steps

Follow-up includes assessment of stone clearance and kidney function. Imaging may be performed to confirm successful treatment, and further advice is provided to reduce the risk of stone recurrence and support long-term kidney health.
