DONORS WITH HYPERTENSION
Hypertension Family Risk If one of your parents is affected by high blood pressure, you have a 25% chance of developing the disease. The risk increases if both parents or if a parent and a sibling have hypertension. If both parents suffer from hypertension, your odds increase to 50%.
Gestational HTN 15,000 women F/U: women with recurrent hypertensive disorders in pregnancy are likely to have higher BMI, higher BP, worse lipids several years after pregnancy. 2 episodes pre-eclampsia 10 X chance of requiring BP meds later on Obstetrics & Gynecology: Volume 114(5), November 2009, pp 961-970

Stone Disease 300 asymptomatic stone patients, avg age 62, stones 10 mm, 85% calcium stones, followed for 3 years Stone growth in 60%, intervention in 26% Stone size 4mm or less located in upper pole had least problems Urine and serum uric acid correlated with stone growth Conclusion: small, upper pole stones, negative metab W/U appear to be safest Progression of Nephrolithiasis: Long-Term Outcomes with Observation of Asymptomatic Calculi. J Endourology: 18 (6). 2004
Donor with microscopic hematuria
Microscopic Hematuria 10 potential donors with micro hematuria were biopsied 1 IGAN, 4 Thin BM disease, 2 Nl, 1 HTN changes, 2 other. 4/10 ended donating (2 Nls, 2 TBMD) Koushik R, et al, Transplantation, 2005
Donors at risk for DM 2
Spectrum of DM
Familial risk DM 3000 patients at Joslin 1990s: Type 2 diabetes is transmitted primarily through an affected parent (more often the mother). The diabetes risk in siblings of index cases without a history of diabetes in a parent was similar to that in the general population. Diabet Med. 2002 Jan;19(1):41-50.
Risk of Type 2 DM after Gestational DM Gestational Diabetes in the United States 2 to 10 percent of pregnancies. Women who have had gestational diabetes have a 35 to 60 percent chance of developing diabetes in the next 10 20 years. National Diab Information Clearinghouse (NIDDK)
DM Nephropathy 5100 type 2 diabetic patients enrolled in UKPDS, avg age 52, 82% white, 8%black. At ten years following diagnosis, the prevalence of microalbuminuria was 25%. Development and progression of nephropathy in type 2 diabetes: the United Kingdom Prospective Diabetes Study (UKPDS 64). Adler AI, Stevens RJ, Manley SE, Bilous RW, Cull CA, Holman RR, UKPDS GROUPSOKidney Int. 2003;63(1):225.
Diabetic Nephropathy in African Americans Type 2 diabetes mellitus is 1.4 to 2.2 times more prevalent in African Americans than whites. Plus higher rates of micro- vascular complications. 2-3 X rate of ESRD than whites Current Diabetes Reports 2004, 4:455 461

Donor Nephrectomy SRTR 2010
Open donor Nephrectomy Donor Disincentives Incisional morbidity Pain cosmesis Prolonged recovery 4-12 weeks Lost wages Personal obligations Child care
Laparoscopic Live Donor Nephrectomy (2000-2009) Advantages to donor Decreased morbidity Less postoperative pain Less incisional morbidity Better cosmesis Hastens return to normal activity Expansion of potential donor pool >900 cases at NYPH/Weill Cornell 4 conversions to open surgery
LaparoEndoscopic Single Site (LESS) Surgery 2009-10 Laparoscopic procedure through a single skin incision, possibly hidden in umbilicus Potential Advantages Less scarring/better cosmesis Move towards scarless surgery Quicker recovery Natural orifice surgery Fewer ports Eliminate trocar site pain Bowel herniation Umbilicus
Laparoscopic Live Donor Nephrectomy Frequent post-operative issues Abdominal bloating Shoulder discomfort Constipation Loss of appetite Pain Intravenous medication x 24 hours Oral pain medication on day #2 and at home Pain medication frequently prolongs above issues
Laparoscopic Live Donor Nephrectomy After surgery in hospital Day 1 Bladder catheter removed the morning after surgery Walking morning after surgery Clear liquid diet Day 2 Solid food Discharge home

The Living Donor Coordinator Who are we? What do we do every day? Do we ever stop and think about these questions?
The Living Donor Coordinator Designated LD coordinator: Why have a LDC? Are there benefits to the donor? How does your center benefit?
The Living Donor Coordinator The Living Donor Coordinator will demonstrate knowledge and ability to facilitate living donation/transplantation, and will utilize that knowledge to coordinate the care of the living donor for evaluation and live organ donation. NATCO Core Competencies
Core Competencies Identifies appropriate live donor candidates. Understands the contra-indications to live donation. Interacts with appropriate staff to facilitate evaluation Identifies requirements for and maintains confidentiality of the living donor evaluation Primary source to ensure living donor has received informed consent Ensures process of informed choice according to transplant center protocol Coordinates with the multidisciplinary team the evaluation process for the potential living donor. Documents pertinent information to ensure continuity of care. NATCO Core Competencies
Core Competencies LDC applies knowledge of growth, development, educational and cultural background during live donor candidate and family interactions. Identifies Donor s: Learning needs Coping skills Decision making process Long term expectations Commitment regarding the donation process NATCO Core Competencies
Core Competencies Educates live donor and family on: Evaluation Donation Hospitalization Process Risks Benefits Educate the donor and family on : Potential short and long term implications to health after donation Follow up commitment both short and long term Identifies and responds to the educational, psychosocial, and economic needs of the live donor candidate and family during evaluation/surgical procedure and post operative course NATCO Core Competencies
Core Competencies Reviews with multidisciplinary team Participates in determination of donor's suitability to donate according to center protocol and OPTN/UNOS regulations Identifies contra-indications to donation Facilitates admission with donor and recipient Available to donor during perioperative period Assists with physical and emotional rehabilitation Discharge plan NATCO Core Competencies
Core Competencies Maintains/ensures communication with donor s primary care physician Other health care providers at donor s request Communicates throughout the evaluation, surgical procedure and post operative phase Verbalizes understanding of center protocol Acts as resource for internal and external health care providers Familiar with OPTN/UNOS regulations Designated LDC Provides improved outcomes for donors Continuity of care NATCO Core Competencies
Role of LDC in Paired Exchange Educate live donors, family, professional staff on paired exchange process Develop rapport with colleagues Coordinate and plan exchanges Review outside records Logistics planning Support donor and family throughout process Evaluate potential donor as bridge donor
Professional development Obtains and maintains ABTC certification Research Reviews and integrates into practice the current literature in the field of living donation Networks through professional organizations.
