Single Incision Donar Nephrectomy

What is Single Incision Donar Nephrectomy?

Single-incision donor nephrectomy (SIDN) is a minimally invasive surgical procedure performed to remove a healthy kidney from a living donor for the purpose of kidney transplantation. This surgical technique is designed to reduce the invasiveness of the procedure, minimize scarring, and potentially enhance the donor's post-operative recovery. In traditional donor nephrectomy, several small incisions are made in the donor's abdomen to access the kidney, and the kidney is then carefully removed. Single-incision donor nephrectomy takes a more advanced approach, where the entire procedure is performed through a single small incision, usually hidden within the donor's belly button (umbilicus) or in the lower abdomen.

Here's an overview of the steps involved in single-incision donor nephrectomy:

• Anesthesia: The living kidney donor is placed under general anesthesia to ensure they are unconscious and pain-free during the surgery.
• Single Incision: Instead of making multiple incisions, the surgeon makes a single small incision (typically 2 to 3 centimeters) either in the belly button or lower abdomen.
• Trocar Placement: A special surgical port called a trocar is inserted through the single incision. The trocar serves as a gateway for surgical instruments, including a high-definition camera and specialized instruments.
• Robotic or Laparoscopic Assistance: Single-incision donor nephrectomy can be performed using either conventional laparoscopic instruments or with the assistance of robotic surgical technology. The surgeon controls the instruments from a console in the operating room.
• Kidney Dissection: The surgeon carefully dissects the kidney from the surrounding tissues while ensuring minimal trauma to the organ.
• Vascular Control: The blood vessels supplying the kidney (renal artery and vein) are meticulously isolated and secured to prepare for kidney removal.
• Kidney Removal: Once the vascular connections are controlled, the kidney is carefully removed from the donor's body.
• Closure: After kidney removal, the incision is closed with sutures or surgical glue, resulting in minimal scarring.

Single-incision donor nephrectomy offers several potential benefits, including a reduced number of incisions, less post-operative pain, shorter recovery time, and improved cosmetic outcomes compared to traditional multi-incision donor nephrectomy.

Why and when is Single Incision Donar Nephrectomy?

Single-incision donor nephrectomy (SIDN) is performed for living kidney donation. The procedure is considered when a healthy individual voluntarily decides to donate one of their kidneys to a recipient in need of a kidney transplant. Kidney transplantation is often the best treatment option for end-stage kidney disease, and living donor kidney transplantation can offer significant benefits, including better long-term outcomes and shorter waiting times compared to deceased donor transplants.

Here are some reasons why and when single-incision donor nephrectomy is considered for living kidney donation:

• Minimally Invasive Approach: Single-incision donor nephrectomy is a minimally invasive surgical technique that offers advantages over traditional multi-incision donor nephrectomy. It involves making a single small incision, typically hidden in the donor's belly button or lower abdomen, which can result in less post-operative pain and faster recovery.
• Cosmesis: The single-incision approach may lead to improved cosmetic outcomes as the scar is hidden in the natural folds of the belly button or lower abdomen.
• Donor Safety: Single-incision donor nephrectomy aims to reduce the potential risks associated with multiple incisions while ensuring the best possible outcomes for the living donor.
• Rapid Recovery: The minimally invasive nature of single-incision donor nephrectomy may lead to a shorter hospital stay and quicker return to daily activities for the donor.
• Donor Convenience: Some living kidney donors may prefer the single-incision approach for its potential benefits, including fewer visible scars and a potentially more comfortable recovery.

The timing of single-incision donor nephrectomy will depend on the donor's and recipient's medical evaluations, compatibility, and logistical factors. The donor's decision to undergo the surgery is voluntary and typically made after extensive medical and psychological assessments to ensure that the donor is healthy and able to withstand the surgery and recovery process.

How is Single Incision Donar Nephrectomy different from the conventional treatment?

Single-incision donor nephrectomy (SIDN) and conventional treatment approaches for living kidney donation differ mainly in the surgical technique used and the number of incisions made during the procedure. Here are the main differences between single-incision donor nephrectomy and conventional multi-incision donor nephrectomy:

Surgical Approach:

• Single-Incision Donor Nephrectomy: As the name suggests, SIDN involves making only one small incision, typically hidden in the donor's belly button (umbilicus) or lower abdomen. Through this single incision, a surgical port (trocar) is inserted to provide access for the surgical instruments, including a high-definition camera and specialized tools used to remove the kidney.
• Conventional Multi-Incision Donor Nephrectomy: In conventional multi-incision donor nephrectomy, multiple small incisions are made in the donor's abdomen. These incisions serve as access points for the surgical instruments and camera. The number of incisions may vary depending on the surgical technique used.

Number of Incisions:

• Single-Incision Donor Nephrectomy: SIDN involves only one small incision, resulting in reduced visible scarring and potentially improved cosmetic outcomes.
• Conventional Multi-Incision Donor Nephrectomy: Conventional donor nephrectomy typically involves two to four small incisions, which may lead to more visible scarring compared to SIDN.

Post-operative Pain and Recovery:

• Single-Incision Donor Nephrectomy: Due to the reduced number of incisions, SIDN may be associated with less post-operative pain and discomfort, potentially leading to a quicker recovery for the living donor.
• Conventional Multi-Incision Donor Nephrectomy: Although generally well-tolerated, the presence of multiple incisions in conventional donor nephrectomy may result in slightly more post-operative pain and a slightly longer recovery period compared to SIDN.

Cosmesis:

• Single-Incision Donor Nephrectomy: SIDN offers improved cosmesis since the single incision is often hidden within the belly button or lower abdomen, leading to a less noticeable scar.
• Conventional Multi-Incision Donor Nephrectomy: The presence of multiple incisions in conventional donor nephrectomy may result in several small scars on the donor's abdomen.

It's important to note that the overall purpose of both SIDN and conventional multi-incision donor nephrectomy is the same: to remove a healthy kidney from the living donor for the purpose of kidney transplantation.

How is life after Single Incision Donar Nephrectomy?

Life after single-incision donor nephrectomy (SIDN) for living kidney donation is generally positive for many donors. The procedure is designed to be minimally invasive, with a focus on reducing post-operative pain, promoting a faster recovery, and allowing donors to resume their normal activities relatively quickly. Here are some aspects of life after SIDN:

• Improved Quality of Life: Many kidney donors experience an improved sense of well-being and satisfaction after helping a loved one or even a stranger by donating a kidney. Knowing that they have made a significant and life-changing impact on someone else's life can bring a sense of fulfilment and joy.
• Quicker Recovery: SIDN is a minimally invasive procedure, and donors often experience a faster recovery compared to conventional multi-incision donor nephrectomy. The reduced post-operative pain and smaller incision contribute to a quicker return to daily activities and work.
• Physical Activity: Donors are encouraged to gradually resume physical activities and exercise after the recovery period. The specific timeline for resuming activities will vary depending on individual healing and the surgeon's recommendations.
• Minimal Scarring: Since SIDN involves a single small incision, the visible scarring is usually minimal and may be hidden within the belly button or lower abdomen. The cosmetic outcome is often improved compared to traditional multi-incision donor nephrectomy.
• Long-term Health: Research studies have shown that living kidney donors generally have a life expectancy and overall health similar to that of non-donors.
• Ongoing Health Monitoring: After donation, living kidney donors are advised to undergo regular health check-ups to monitor their kidney function and overall health. The remaining kidney typically compensates for the loss, and most donors do not experience any significant health issues related to kidney donation.
