iliac stenosis that required dilatation. Overall results: mean time to reach nor- mal renal function (creatinine 2mg/dl) was 22 days. There were three deaths: one postoperatively, one two years after the implant with no renal function, and one with normal renal function. Graft sur- vival at 1 and 5 years is 85 and 72% re- spectively. Patient survival is 95% at one year, remaining stable at 76% from the 2nd year of follow-up. Conclusion: Third kidney transplant is a good therapeutic option for patients with two previous graft losses. Early and late complications were not different from 1 st and 2 nd implants in our series. The re- peated use of the iliac fossa has not impli- cated more surgical complications in our experience.

We have chosen a protocol that mixes pathologic and functional criteria and do- nor age. In this paper, we present our protocol and outcome of our series. Methods: In December 1996, our group started a protocol to optimize the use of kidneys from cadaveric older donors. The protocol is as follows: a renal biopsy was made in all the kidneys. A double kidney transplant was made if: a) donors were over 75 years and renal biopsy showed less than 50% glomerulosclerosis (GE); or b) donors were between 60 and 74 years and renal biopsy had between 15 to 50% GE. A simple kidney transplant was per- formed when grafts were from donors between 60 and 74 years and the biopsy had less than 15% GE. Receptors of these implants were also elderly patients. A de- scriptive analysis of the results was made. Results: 304 (30.4%) out of 1000 kidney transplants performed in our centre (De- cember 1996 –December 2004) were from donors over 60 years old. 82 were double and 222 single. Mean donor age of the dou- ble and single transplants series were 75 and 68 respectively. Immunosuppression was done with triple therapy (steroidsMMF cyclosporine/tacrolimus). Actuarial graft survival at 4 years is 79% for the double transplant group and 78% for the single group (excluding death of pa- tients with functioning kidney). With 4 years of follow-up, mean serum creatinine is 1.8 mg/dl (0.9) for the double implant series and 2.1mg/dl (0.7) for the single. Conclusions: The results of grafts from older donors, used either in a single or double fash- ion, are excellent. Our protocol, using frozen renal biopsies of the kidneys and donor age, allows us to optimize these grafts, with guar- antees of good long-term outcome.

Methods: We analyzed 1420 renal trans- plants done in our department between June 1980 and December 2005 (Table 1). Of those, 250 (14,4%) lost their graft during the first year after the renal trans- plant. We analyzed the demographics of these patients (Group A), comparing them with the remaining patients (Group B), in terms of causes of graft loss. We also studied the acute rejection episodes and renal function, among other characteristics. Results: There were differences in the causes of graft loss and associated pa- thologies in the two groups. In a statisti- cal analysis, immediate renal function, donor age and receptor age were the main factors predictive of graft sur- vival. Conclusion: There are several factors associated with an increased risk of graft loss that should be corrected.

And approximately 50% of these patients have concomitant diseases, like diabetes, severe hyperten- sion, arteriosclerosis and cardiovascular diseases. The aims of the old-to-old renal transplantation program are to shorten the waiting time, shorten the cold ischemic time and use the so-called marginal or- gans. Methods: The inclusion criteria for this program are: 1. donor and recipient are 65 years or older, 2. AB0-compatibility and, 3. local transplantation with a short cold ischemic time. We reviewed the re- sults of the patients transplanted at our centre regarding patient survival, graft survival, graft function and some other parameters. Results: From January 1999 to January 2003 we performed 44 renal transplanta- tions within the old-to-old-program. The median age of the donors and the recipi- ents was 69.2 years (range 65-77 years) and 66.4 years (range 55-72 years) re- spectively.

Introduction and Objective: More than60% of patients with chronic renal failureon the transplantation waiting lists areolder than 65 years. And approximately50% of these patients have concomitantdiseases, like diabetes, severe hyperten-sion, arteriosclerosis and cardiovasculardiseases.

and three of unknown causes. Four pa-tients (9.1%) had a primary graft mal-function and seven patients (15.9%) re-turned to dialysis 3 to 23 months postoperatively because of chronic graft dys-function. In the remaining 27 patients(61.3%), the graft function was sufficientto avoid hemodialysis.Conclusions: Our results are compara-ble with the results of other centers. Bycareful selection of elderly patients withchronic renal failure for transplantation,it is possible to achieve saticfactory re-sults regarding patient survival, graft sur-vival and good quality of life. Personswith severe comorbid conditions shouldbe excluded from renal transplantation.Dialysis is an alternative option for thesepatients.

PD-09.10Experience with 350 cases oflaparoscopic live donor nephrectomy;development of cost-effectivetechniquesKumar A, Gupta N, Srivastava A,Dubey DSGPGIMS, Lucknow, India

Introduction: Laparoscopic instrumenta-tion poses a significant cost burden topatients in developing countries. Wepresent herein the development of cost-effective techniques of laparoscopic livedonor nephrectomy at our institution.Materials and Methods: Between 1999-2005, 350 patients underwent laparo-scopic live donor nephrectomy at our in-stitution. The first 75 patients underwenta lap-assisted procedure (LADN) whererenal mobilization was performed laparo-scopically and hilar clamping and renalextraction were done through a subcostalincision. 136 patients underwent a stan-dard laparoscopic DN where hilar clamp-ing was performed using Hemo-Lok clipsand renal extraction carried out through a5cm flank incision or a Pfannensteil inci-sion. 40 patients (8-right, 23-left) under-went retroperitoneoscopic donor ne-phrectomy (RDN) where renal extractionwas done by flank, Pfannensteil or lumbarincisions.Results: Conversion to open nephrec-tomy was required in 12 (4%) patients.Two patients were re-explored forbowel injury and 2 for haemorrhage.One patient developed post-operativehydro-pneumothorax that required chesttube drainage. Blood transfusion wasrequired in 22 (7.33%) patients. Themean warm ischemia time was 3.2 min-utes (range 2-13 minutes). Costly dispos-

able like extraction devices or GIA sta-plers were not required in any case. Wecan cut down the costs by using all me-tallic autoclavable instruments and he-molock clips.Conclusions: In developing countries,innovative cost saving strategies canbe developed to transfer benefits oflaparoscopic donor nephrectomy to liv-ing donors without imposing a cost bur-den.

PD-09.11Radiocephalic fistula at elbow-Asimple solution to prevent vascularsteal syndrome associated withbrachiocephalic fistula: review of over300 casesKumar A, Gupta N, Srivastava A, DubeyD, Raina P, Vijjan VK, Jha MSGPGIMS, Lucknow, India

Introduction: Brescia-Cimino internalarteriovenous fistula at wrist introducedin 1966 is the vascular access procedureof choice for dialysis, even today. Fail-ure of arteriovenous fistula at wrist ornon-availability of a peripheral vein inthe vicinity of radial artery necessitatesthe creation of brachiocephalic fistula atelbow. The most troublesome complica-tion of brachiocephalic fistula is vascularsteal syndrome. The reported incidenceranges from 1.6 to 20%. Making end toside radiocephalic fistula at elbow caneasily prevent this.Materials and Method: We have per-formed over 300 radiocephalic/ radio-median vein fistula at elbow over past15 years. A 4-5 cm transverse incisionwas given over the brachial artery, 2fingerbreadths below the elbow crease.If median cubital vein is found it is anas-tomosed to the radial artery just distalto the brachial artery bifurcation or elsethe cephalic vein was used at the samelevel. We present our experience inradiocephalic/radio-median fistulaat elbow with particular emphasis onthe management and prevention of thecomplications of vascular access sur-gery.Results: One-year patency rate in our pa-tients was over 90%. None of our patientshad vascular steal phenomenon.Conclusion: Radiocephalic fistula at el-bow is a good alternative to brachioce-phalic fistula with no incidence of vascu-lar steal phenomenon in our experience.Most of the complications of vascular ac-cess surgery are preventable. When thesecomplications occur, the best possible

salvage is in the hands of experiencedvascular surgeons only.

PD-10.01Long-term survival of inflatable penileprosthesesWilson SK, Delk Jr. J, Neeb A, Cleves MUniversity of Arkansas, Little Rock, AR,USA

Introduction and Objective: Long-termrevision-free survival greater than 5 yearshas never been reported for inflatable pe-nile prostheses. We conducted a prospec-tive study of almost 6000 implant surger-ies (original implant, revisions, removals)involving 14 different models over the lasttwo decades by the same surgical team.From this data we estimated 10 and 15years-survival of first time (virgin) implan-tations in 2384 patients with 4 differentmodels.Methods: Data was obtained from medi-cal records and patient interviews, en-tered into a computerized database andanalyzed by a third party. Information in-cluded implant type, date, revision historywith date and reason. 14 different in-flatables were examined. Mentor Alpha 1,Mentor Alpha NB, AMS 700 CX and AMS700 Ultrex had usage for an extended pe-riod of time. Because of failure times be-ing confounded due to prior implants,only virgin implants were examined. Revi-sion free survival was estimated using theKaplan-Meier product limit method andcompared using the log rank test.Results: For the entire series estimated10-years revision-free survival for all rea-sons was 68.5% and the 15-years revision-free survival was 59.7%. Freedom frommechanical breakage at 10 years was79.4%; 15-years was 71.2%. Recent me-chanically enhanced models did even bet-ter. In 1992 Mentor Alpha added pumpreinforcement to forestall mechanicalbreakage (J Urol 162:715, 1999). This im-proved 10-years survival from 65.3% to88.6% (p�0.0001). In 1/01 AMS CX addeda Paralyne coating to the cylinders thatincreased 3-years mechanical survival from88.4 to 97.5% (p�0.0032). Thus far, theenhanced CX 3-years revision-free survivalfrom revision for any cause of 87.4% issuperior to the 78.6% revision-free sur-vival for historical non-coated inflatables(p�0.0002) and similar to the enhancedMentor Alpha 1 (86.7%).
