renal transplantation, living kidney dona- tion has evolved to much variation. Our objective is to explain and define “Nationality-related” type of living dona- tion as an extension of Iran Model, that is controlled Living Unrelated Donors (LURD with some rules such as the same nation- ality of donors and recipients. Methods: Our data is based on data bank of Management Center for Transplantation and Special Diseases (MCTSD) affiliated to the Iranian Ministry of Health. We analyze the program of living donation in last 2 decades in Iran. Kidney transplantation has been performed with a high rate. Up to end of 2006 more than20000 kidney transplantations were done in Iran. Al- though cadaveric donation has been per- formed from 7 years ago after passing the related act in the parliament, but most of this activity is LURD. Results: The 1988 war caused a restricted hemodialysis due to insufficient financial resource. Cadaver donation was not legal at the time. So, a controlled LURD was adopted. Since then the activity of renal transplantation has increased rapidly up to now and eliminated its waiting list. This rate is more than 1600 per year (24 PMP). Eighty percent of donation type is LURD. Almost 50% of ESRD patients undergo re- nal transplantation. Fifty percent of these patients are in low socioeconomic class. All donors for these patients are Iranian nationals. None are foreigners or refugees which a great number of them live for a long time in Iran. Also, no foreigner is allowed to receive kidney transplantation from Iranian donor. About 150 patients from neighboring countries were trans- planted in Iran each year that all of recipi- ents and donors were from the same na- tionality. Conclusions: Iranian model for kidney transplantation is a national controlled program. It has prevented patient death and suffering. At least 50% of patients are in low economic class. This model has eliminated renal transplantation waiting list in this country. An efficient rule of this model is the same nationality of do- nors and recipients. We has named this type of donation as “nationality related” that argue for widespread adoption in other countries with similar socioeco- nomic conditions. MP-15.05 Comparison of outcome in renal transplant recipients with respect to arterial anastomosis: the internal versus the external iliac artery - a prospective randomized study Bahlooli A, Amjadi M, Zomorrodi A, Barhaghi H Department of Urology and Renal Trans- plantation, Imam Khomeini Hospital, Tabriz University of Medical Science, Tabriz, Iran Introduction: Kidney transplantation is the treatment of choice for the end-stage renal disease, and surgical techniques have become well developed in the past three decades. Arterial reanastomosis is one of the most important technical as- pects of renal transplantation which influ- ences the outcome directly. There are two usual sites for arterial anastomosis: internal iliac artery and external iliac ar- tery. The internal iliac artery is unsuitable for anastomosis in some cases such as obese recipients, history of pelvic surgery, male recipients, and mismatch of diame- ters between internal iliac artery and allo- graft artery. In these conditions, external iliac artery will be preferred (if its compli- cation rate and allograft outcome could be similar to internal iliac). This study tried to compare two types of arterial reanasto- mosis from the outcome and complica- tions points of view. Materials & Methods: A total of 61 cases of renal transplantation which are per- formed from July 2002 to April 2003, are included in an experimental study. All grafts were from living donors. Recipients are randomized into two groups, internal (renal artery anastomosis to internal iliac artery) and external (renal artery anasto- mosis to external iliac artery). During 3 months of follow-up postoperatively, allo- graft function and early surgical complica- tions were evaluated. Results: Except for two cases of death due to medical complications and two cases of graft-loss due to venous thrombo- sis (both in internal group), other grafts had normal or near normal function. In 6 recipients, stenosis of arterial anastomosis was reported in ultrasonography (four in internal group and two in external). Discussion & Conclusion: The rate of complications and criteria chosen for allo- graft function and transplant success, were not significantly different in two groups, so it can be concluded that arte- rial anastomosis of kidney allograft to ex- ternal artery is a suitable alternative (and in some cases such as obese recipients and not suitable internal iliac artery is pre- ferred) to internal iliac artery without any increased rate of complications. MP-15.06 10 years experience in renal transplantation challenged by renal graft vascular anomalies Sinescu I, Ha ˆrza M, Serbanescu B, Manu M, Tacu D, Kerezsy E, Domnisor L, Daia D Center of Surgical Urology, Dialysis and Renal Transplantation, Fundeni Clinical Institute, Bucharest, Romania Introduction: Kidney normal vascular anatomy requires a single artery and a sin- gle vein but only 65% of cases respect this. In the literature, 35% of cases have multiple arteries and/or veins. The aim of the study was to assess if abnormal renal vascular anatomy represented a problem in performing transplantation and to prove the limits of abnormal renal pedicle surgical reconstruction. Material & Methods: Ten years of kidney transplant experience is presented in our study (June 1997 – April 2007). Since 1997, 751 renal transplants have been per- formed, 645 from living donors (86%) and 106 from brain-death donors (14%). 231 cases (31%) presented vascular abnormal anatomy, 149 cases abnormal arteries and 82 cases abnormal veins. In all of these cases transplantation was performed using special anastomotic techniques. Results: Special vascular anastomotic techniques were used as followed: double T-T anastomosis were performed to the internal iliac artery branches in 93 cases, T-L anastomosis to the external iliac artery using an aorta patch - 7 cases (cadaver donors), combined anastomosis, T-T to the internal iliac artery and T-L to the ex- ternal iliac artery in 3 cases; in 22 cases we made a single trunk using two renal arteries or branches, and in 3 cases we performed T-T anastomosis of aberrant arteries to the inferior epygastric artery. 27 minor aberrant vessels were excluded. Cava patch for multiple veins was anasto- moted T-L to the external iliac vein in 27 cases (7 from cadaver donors). In cases with abnormal venous systems classical T-L anastomosis to the external iliac vein was a routine. Conclusions: Abnormal vessels anatomy was found in one third of cases but trans- plantation was performed using special anastomotic techniques. More than two graft arteries contraindicates the harvest- ing act from living donor, which can be accepted only in very selected cases. In order to choose the kidney from living donors, the transplant team is guided by two criteria: in case of equal kidney’s function, the easier technical surgical one will be donated; in case of unequal kid- ney’s function, the weak one might be MODERATED POSTER SESSIONS 118 UROLOGY 70 (Supplment 3A), September 2007
