Understanding Kidney Cyst Treatment in Singapore
Kidney cysts are fluid-filled sacs that develop on or within the kidneys. Most kidney cysts are benign and often go unnoticed. However, some kidney cysts can grow large or become infected without causing symptoms in the early stages. Timely diagnosis and personalised management are important to relieve discomfort and rule out complex or cancerous cysts.

What Is Kidney Cyst?
A kidney cyst is an abnormal, fluid-filled sac that forms on the surface (cortical cyst) or within the kidney. While most are simple cysts that are non-cancerous, some are complex cysts and require further evaluation to exclude malignancy.
Types of kidney cysts include:
Symptoms of Kidney Cysts
Kidney cysts typically cause no symptoms unless they enlarge or become complicated. When symptomatic, patients may experience:
Don’t ignore kidney cyst symptoms. Early assessment helps protect your kidney health and prevent complications.
How Kidney Cysts Is Diagnosed
A thorough assessment is performed to determine the cyst type and its impact on kidney function.
Treatment Options & Surgical Procedures
The management of kidney cysts depends on their size, complexity, and symptoms. Our goal is to relieve discomfort, prevent recurrence, and preserve kidney function.
Suitable for small, simple cysts without symptoms.
Regular ultrasound or CT scans are scheduled to ensure the cyst remains stable.
Performed under local anaesthesia as a day procedure.
A fine needle is used to drain the cyst fluid, followed by injection of a sclerosing agent (such as ethanol) to reduce recurrence.
Quick recovery, minimal downtime.
Minimally invasive surgery performed through small keyhole incisions.
The cyst wall is removed to prevent fluid reaccumulation.
Recommended for large, painful, or recurrent cysts.
Most patients stay in hospital for 2–3 days and return to light activity within 1–2 weeks.
Considered for complex or suspicious cysts (Bosniak III–IV) where malignancy cannot be ruled out.
The affected portion of the kidney is removed with precision, preserving healthy tissue.

Simple cysts rarely affect kidney function. Large or multiple cysts may occasionally compress kidney tissue and require monitoring.
No. While they may remain stable for years, cysts generally do not disappear without treatment.
Recurrence is uncommon after laparoscopic surgery but may occur following aspiration alone.
No. Most simple, asymptomatic cysts can be safely monitored with periodic imaging.
