It is perfectly natural to feel anxious or worried when a doctor recommends kidney surgery for you or a loved one. Given that the kidneys are vital organs, such concerns are completely understandable. Please rest assured that your medical team understands your feelings and is here to support you. They will explain the procedure, the expected outcomes, and the recovery process in detail to put your mind at ease.
What is a Heminephrectomy?
A heminephrectomy is a surgical procedure where only the non-functioning portion of a kidney is removed. Your surgeon will not remove the entire organ, but rather just the section that is no longer working properly.
This procedure is typically performed in cases of a Duplex Kidney. You may be wondering what that means.
Normally, each of us has two kidneys. Typically, each kidney has one ureter (the tube that carries urine to the bladder). However, some individuals have a congenital condition where one kidney is associated with two ureters; this is known as a Duplex Kidney.
Please note that not everyone with a Duplex Kidney experiences issues. Many people live their entire lives without even knowing they have this condition. However, it can sometimes lead to certain complications that require medical attention.
What complications can a Duplex Kidney cause?
A Duplex Kidney can lead to three primary complications. Let's look at what they are.
| Condition | In Simple Terms… |
|---|---|
| Vesicoureteral Reflux (VUR) | This occurs when urine flows backward from the bladder toward the kidneys. Over time, this can lead to permanent kidney damage. |
| Ectopic Ureter | This happens when a ureter connects to an organ other than the bladder. This misconnection can cause damage to that surrounding organ. |
| Ureterocele | The lower end of the ureter swells like a balloon inside the bladder, obstructing normal urine flow. This causes pressure to build up, potentially damaging the kidney. |
While these conditions exist, your Nirogi Lanka specialist will often start by monitoring your progress. However, if you experience frequent urinary tract infections or if the aforementioned issues have caused complete loss of function in a portion of your kidney, your doctor may recommend a heminephrectomy.
How should you prepare for surgery?
Before your procedure, your urologist will explain the surgery in detail and obtain your informed consent. You will also undergo preoperative testing to ensure you are healthy enough for the procedure. Your medical team will specifically discuss:
- Your full medical history.
- All medications you are currently taking. This includes prescriptions, over-the-counter drugs, herbal supplements, and vitamins. Some medications, particularly blood thinners, must be paused as they increase bleeding risks.
- Any known allergies you have.
You will receive clear instructions on when to stop specific medications and when to begin fasting (avoiding food and drink) prior to your surgery.
How is the surgery performed?
There are three primary approaches: open surgery, laparoscopic surgery, and robotic-assisted surgery.
| Surgical Method | Approach and Advantages |
|---|---|
| Open Heminephrectomy | The surgeon makes an incision of approximately 12 inches along the side between the ribs and hip, allowing direct access to the kidney to remove the non-functioning part. |
| Laparoscopic Surgery | Instead of one large incision, several small punctures are made. A camera (laparoscope) and specialized instruments are inserted to perform the removal. This results in smaller scars and faster recovery. |
| Robotic Surgery | Similar to laparoscopy, but your surgeon controls robotic arms with high precision, allowing for enhanced accuracy during the procedure. |
Before the surgery begins, the anesthesiologist will administer general anesthesia, ensuring you are asleep and feel no pain. A urinary catheter (Foley catheter) will also be placed to keep the bladder empty. The procedure typically takes two to three hours.
What happens after surgery, and what is the recovery time?
You will be monitored in the recovery room until you are awake and your vitals are stable. Pain management medication will be provided as needed.
Recovery time depends on the surgical approach:
- Following laparoscopic or robotic surgery, you can usually return to normal activities within 4-6 weeks.
- Following open surgery, full recovery may take 8-12 weeks.
During recovery, your doctor will encourage light walking to boost circulation and prevent complications like blood clots or pneumonia. However, you must avoid lifting anything heavier than 4.5kg (about the weight of a gallon of water).
Dietary considerations
Yes. For the first four weeks, aim to drink 6-8 glasses of water daily and focus on easily digestible, soft foods. You may be advised to avoid certain foods until your bowel movements return to normal.

When to Contact Your Doctor Immediately
If you experience any of the following symptoms after your surgery, please contact your doctor immediately or visit the nearest Emergency Department.
- Difficulty breathing
- Excessive bleeding at the incision site
- Separation of the wound edges
- Signs of infection: This includes redness, swelling, purple/brown/black discoloration around the site, fever, or discharge with a foul odor.
- Unbearable or worsening pain
- Pain in the legs
- Blood in your urine
It is perfectly normal to feel anxious about surgery. Questions like, "Will the surgery be successful?" or "What if my symptoms worsen?" are natural. Try to focus on the positive outcome: "How much better will my quality of life be after this?" or "Will this finally end those recurring infections?" Shifting your perspective can help you feel more at ease during your recovery.
