Kidney cancer: diagnosis and specialized treatment

Kidney cancer is a urological tumor that develops in the kidney tissue and can often progress without causing symptoms in its early stages. Thanks to advances in diagnostic imaging and minimally invasive surgery, it is now possible to detect the disease early and apply more precise and conservative treatments.

Detection and context

In many cases, the diagnosis is made incidentally during imaging tests ordered for other reasons, as it may not produce obvious symptoms in its early stages. As the disease progresses, some patients may experience blood in the urine, persistent lower back pain, or the appearance of an abdominal mass. Early detection is crucial to increase the chances of curative treatment and preserve as much healthy kidney tissue as possible. The diagnostic workup typically includes imaging tests such as ultrasound, computed tomography (CT) scans, or magnetic resonance imaging (MRI), which allow for the determination of the tumor's size, location, and extent. Individualized clinical assessment allows for the selection of the most appropriate treatment strategy based on the tumor's characteristics, the patient's age, kidney function, and the potential involvement of other structures.

Early detection is essential

Early signs of cancer

• Blood in the urine

• Persistent lower back pain

• Appearance of an abdominal mass

Types of treatment or surgery

Kidney cancer treatment must be tailored to each patient's specific characteristics and the stage of the disease. Currently, there are various therapeutic options that combine cancer control, kidney preservation, and less invasive techniques.

Partial nephrectomy

This procedure involves removing only the tumor while preserving the rest of the kidney. It is a common option for small, localized tumors.

Radical nephrectomy

This procedure is performed when the tumor is larger or affects a significant portion of the kidney. It involves the complete removal of the affected organ.

Laparoscopic surgery

Minimally invasive technique that allows intervention through small incisions, reducing pain and recovery time.

Robotic surgery

It provides greater surgical precision and better control of complex structures, especially in conservative procedures.

Systemic treatments

In advanced cases, targeted therapies or immunotherapy may be used to control the disease.

How the procedure is performed

Initial assessment

The process begins with a complete clinical evaluation and diagnostic tests to determine the size, location, and extent of the kidney tumor. This information is essential for planning the most appropriate treatment.

Surgical planning

Once the diagnosis is confirmed, an individualized treatment strategy is defined. Whenever possible, conservative and minimally invasive techniques are prioritized to preserve kidney function and reduce complications.

Intervention

The surgery can be performed laparoscopically or robotically, using small incisions and advanced technology to improve surgical precision. Depending on the case, either only the tumor or the entire kidney is removed.

Recovery

Following the procedure, the patient remains under medical supervision to monitor their progress and kidney function. Recovery is usually faster with minimally invasive techniques, allowing for a quicker return to normal activities.

FAQ

We answer some of the most common questions about urological consultations, tests, and treatments.

What symptoms can kidney cancer produce?

In its early stages, it may not cause any symptoms. When symptoms do appear, the most common signs are blood in the urine, persistent lower back pain, or a feeling of a mass in the abdomen. Many cases are detected incidentally through imaging tests.

What is the recovery like after surgery?

Recovery depends on the type of procedure performed. With laparoscopic or robotic techniques, the postoperative period is usually faster, with less pain and a shorter hospital stay.

What risks might the treatment have?

As with any surgical procedure, there are risks of bleeding, infection, or impaired kidney function. Individualized assessment helps minimize complications and improve safety.

What are the differences between open and minimally invasive surgery?

Laparoscopic and robotic techniques allow surgery to be performed through small incisions, promoting faster recovery, less postoperative pain, and better aesthetic results.

Is it possible to save the affected kidney?

Yes. Whenever the characteristics of the tumor allow it, conservative techniques are prioritized to remove only the lesion and preserve kidney function.
