Nephrectomy (kidney removal)

Total or partial removal of a kidney, performed preferably laparoscopically, to treat a tumor or a non-functioning kidney.

What is it?

Nephrectomy is the surgical procedure of removing a kidney, either entirely (total nephrectomy) or in part (partial nephrectomy). It is mainly indicated for kidney tumors, but also when a kidney has been destroyed or is no longer functioning as a result of chronic disease, stones or repeated infections. Whenever possible, the operation is performed laparoscopically: small incisions allow the introduction of a camera and fine instruments, providing high surgical precision with a simpler postoperative course than open surgery. In certain cases of localized tumors, a partial nephrectomy makes it possible to remove only the diseased area and preserve the rest of the kidney. Living with a single kidney is entirely compatible with a normal life: the remaining kidney takes over the entire renal function, provided regular medical follow-up is maintained. At Clinique Pasteur Tunis, nephrectomy is performed by urologists highly experienced in major laparoscopic surgery, with a dedicated laparoscopy unit and an intensive care environment ensuring safe management from start to finish.
Nephrectomy (kidney removal)

When is it indicated?

Kidney tumor confirmed by imaging

When a CT scan or MRI reveals a kidney tumor, its removal — total or limited to the diseased area — is the reference treatment.

Destroyed or non-functioning kidney (repeated infections, stones, chronic obstruction)

A kidney that no longer works can become a source of infections and pain. Removing it eliminates these complications, with the remaining kidney taking over all the work.

Kidney causing severe resistant high blood pressure

In certain rare cases, a diseased kidney sustains very high blood pressure that medications fail to control. Its removal can help normalize it.

Certain symptomatic kidney malformations

When a kidney malformation causes recurrent pain, infections or stones, surgery may be the best way to resolve the problem permanently.

Preparation

1Complete imaging work-up (CT scan or MRI) to characterize the lesion
2Blood tests including assessment of kidney function
3Mandatory anesthesia consultation
4Discontinuation of anticoagulants as medically instructed
5Fasting for 6 hours before the procedure

Procedure

1

General anesthesia

2

Positioning appropriately on the operating table

3

Creation of small incisions for the laparoscopic approach (or a single incision for open surgery)

4

Careful dissection of the kidney and control of its blood vessels

5

Removal of the entire kidney or of the diseased area only

6

Careful verification that there is no bleeding, then closure

7

Close postoperative monitoring

Duration

2 to 3 hours

Aftercare & Recovery

The hospital stay generally lasts a few days. Eating and walking resume early. Kidney function is monitored with simple blood tests, and the remaining kidney gradually compensates. Regular follow-up with the urologist is then put in place.

Risks and side effects

Intraoperative bleeding, controlled thanks to preparation and surgical technique
Moderate postoperative pain, well relieved by painkillers
Rare complications related to abdominal surgery, prevented by attentive monitoring

These risks remain rare. Your surgeon will inform you in detail before the procedure.
