Introduction: Three modalities for treating chronic kidney failure are peritoneal dialysis, hemodialysis, and kidney transplantation. Among them kidney transplantation is cost-efficient and leads to a somewhat normal quality of life. In this approach, most often the external iliac artery is selected for anastomosis, but this could be disastrous if anastomosis leads to a complication. The traditional end-to-end approach for anastomosis of the kidney artery to the internal iliac artery leads to pelvic organ ischemia. However, if the end-to-end anastomosis is replaced by an end-to-side approach, it is safer. This report discusses some cases of end-to-side anastomosis using the internal iliac artery.
Method: In ten cases of chronic kidney failure, we anastomosed the kidney artery to the internal iliac artery with an end-to-side approach.
Results: After vessels were unclamped, all patients had diuresis. Their creatinine was in normal range and was blood flow in the internal iliac artery, based on color Doppler ultrasound.
Conclusion: End-to-side anastomosis can be done in some chronic kidney failure patients if their internal iliac arteries are large enough. This approach is safer than anastomosis using the external iliac artery.

Introduction

The most effective treatment for chronic kidney failure is kidney transplantation in which the external iliac artery is used to preserve pelvic organs’ circulation. Using the internal iliac artery for end-to-end anastomosis is a traditional approach for kidney transplantation (Figure 1). Even in repeated kidney transplantation the end-to-end is preferred to the end-to-side approach.

Kidney transplantation is the preferred choice of treatment for chronic kidney failure because it offers the patient a “near normal” lifestyle. Vascular anastomosis is still done according to Alex Carrel’s technique for kidney transplantation and Kuss’ technique for pelvic vessels.1 With this method the hypogastric artery or external iliac artery is selected for vessel anastomosis.

The traditional approach used a pelvic vessel such as the internal iliac artery,2 but later the external iliac artery was used for preserving pelvic organs’ circulation, especially in the penis.3 End-to-end anastomosis using the hypogastric artery has been claimed to reduce the penis’ blood circulation,3 as it is suggested that 50% of chronic kidney failure patients suffer from erectile dysfunction. Some studies suggest that end-to-end anastomosis is an etiology of post-kidney transplantation erectile dysfunction.4 Claudication has also been reported after end-to-end internal iliac artery anastomosis.5

To our knowledge, there has only been one study on end-to-side anastomosis of the internal iliac artery in a general hospital in Leicester, UK.6 Ours is the second to discuss some cases of end-to-side anastomosis using the internal iliac artery in a hospital in Tabirz city, Iran.

Cases

This study was done on ten kidney transplant patients (Table 1). The end-to-side internal iliac artery anastomosis approach was used in all patients.

Table 1 The patient’s age, sex, race, outcomes, and complications

One of the cases was a 45-year-old male with chronic kidney failure because of hypertension. Kidney transplantation was carried out with allograft kidney procured from an unrelated live donor. It was the donor’s left kidney. To prepare the recipient’s hypogastric artery, we performed end-to-side kidney artery anastomosis. After 2 months’ follow-up his creatinine level was normal =0.3 mg/dL (Figure 2).

Another case was a 25-year-old male with chronic kidney failure due to glomerulopathy. We performed end-to-side anastomosis using the hypogastric (internal iliac) artery with good results (Figure 3). His creatinine level was 1.5 mg/dL after 2 months. He was treated with tacrolimus, CellCept® (mycophenolate mofetil), and prednisolone.

Figure 3 End-to-side anastomosis using the internal iliac artery.

In our hospital more than ten kidney transplantations have been performed successfully by end-to-side anastomosis using the internal iliac artery. All of the patients were treated with tacrolimus, mycophenolate mofetil, and prednisolone and their creatinine levels were ≤1.5 mg/dL.

Discussion

The internal iliac artery separates from the common iliac artery. It has nine branches including: sacral, gluteal inferior, gluteal superior, lumbar, umbilical, obturator artery, superior vesical, inferior vesical, and pudendal. In end-to-end anastomosis using the kidney artery we omit nine internal iliac artery branches. This can have consequences for a kidney transplant recipient. For example, omitting the pudendal branch reduces perfusion of penile arteries5 and causes erectile dysfunction; or omission of the gluteal branch causes claudication5 (Table 2).

Table 2 Complications and advantages of internal and external iliac artery anastomosis

Considering that erectile dysfunction is more common in kidney transplant patients, the end-to-side instead of end-to-end anastomosis approach can be useful in a patient with high risk of erectile dysfunction and claudication, especially in young people, if the internal iliac artery is large enough in diameter for anastomosis. Also, if there is arterial plaque, it is possible to perform an endarterectomy and then end-to-side anastomosis to preserve pelvic organs’ perfusion, especially erectile organs’ blood flow.

Conclusion

Chronic kidney failure can be associated with a pelvic organ dysfunction if the hypogastric artery is used for anastomosis. End-to-side anastomosis can be considered instead, to preserve pelvic organs’ blood flow, especially the erectile organs, in young people.

Ethics statement
