OBJECTIVE To present a comparison of perioperative donor outcomes and recipient graft function in a series of patients undergoing laparoendoscopic single-site donor nephrectomy (LESS-DN) versus conventional laparoscopic donor nephrectomy (LDN). METHODS Data were collected for 50 consecutive LESS-DN patients and a matched cohort of 50 LDN patients. The donor outcomes analyzed included operative time, estimated blood loss, complications, visual analog pain scores, and recovery time. The recipient outcomes analyzed included serum creatinine at discharge and follow-up and the incidence of delayed graft function. RESULTS The mean total operative time was shorter in the LDN group than in the LESS-DN group (P < .0001). Linear regression analysis of the LESS-DN operative times relative to case number showed a significant decrease in the operative time with increasing case number (r(2) = 0.19, P = .002). No statistically significant differences were found in estimated blood loss, warm ischemia time, length of stay, or visual analog pain scores between the 2 groups. However, the surgical incision was significantly smaller in the LESS-DN group (P < .0001). After discharge, the patient-reported time to complete recovery was faster in the LESS-DN group (P = .01). The incidence of complications was similar in both groups; however, major complications only occurred in the LDN group. No differences were found in the recipient serum creatinine values or the incidence of delayed graft function. CONCLUSION Our initial experience with LESS-DN is encouraging. This retrospective matched-pair comparison between LESS-DN and LDN suggests that the single-port approach might be associated with quicker convalescence. Longer operative times in the LESS-DN group could simply represent the learning curve of a novel procedure.

PURPOSE We present our initial experience in 40 patients undergoing laparoendoscopic single site donor nephrectomy. MATERIALS AND METHODS We prospectively collected data on 40 consecutive patients. A single access GelPOINT™ device was inserted into the abdomen through a 4 to 5 cm periumbilical incision. We used a bariatric camera with a right angle attachment for the light cord to maximize triangulation. Parameters analyzed included warm ischemia time, operative time, estimated blood loss, visual analog pain score, time to recipient creatinine less than 3 mg/dl, and recipient creatinine at discharge home, and 3 and 6 months. RESULTS A total of 38 left and 2 right donor nephrectomies were performed. Complete laparoendoscopic single site donor nephrectomy was successful in 38 cases. One left and 1 right case were converted to a hand assisted approach. Average ± SD body mass index was 26.1 ± 5.2 kg/m(2). Mean operative time to allograft extraction was 93.5 ± 27.5 minutes and mean total operative time was 166.7 ± 33.8 minutes. Average estimated blood loss was 106.7 ± 93.5 cc. Mean warm ischemia time was 3.96 ± 0.72 minutes. Mean hospital stay was 1.77 ± 0.43 days and median time to recipient creatinine less than 3.0 mg/dl was 54.2 ± 110.3 hours. Mean recipient creatinine at discharge home, and at 3 and 6 months was 1.48 ± 0.67, 1.29 ± 0.38 and 1.19 ± 0.34 mg/dl, respectively. Complications included hyponatremia in 1 patient, wound infection in 1, and a grade III laceration in an allograft that was sustained during extraction. CONCLUSIONS Our initial experience with laparoendoscopic single site donor nephrectomy is encouraging. This approach to kidney donation without an extra-umbilical incision could become particularly relevant to minimize morbidity in young, healthy organ donors.

Serum sickness-like reaction associated with cefazolin

Michael Brucculeri; Marian Charlton; David Serur

BackgroundAlthough rare, serum sickness-like reactions have been documented to occur following the administration of many antibiotics. Cefazolin, a first generation cephalosporin, is a commonly prescribed antibiotic which is considered to be generally safe and well tolerated. There have been no prior reports linking this drug with sickness-like reactions. We report a probable case of serum sickness-like reaction following a single dose of cefazolin.Case PresentationA 23 year old man with no significant past medical history was admitted to undergo a laparoscopic donor nephrectomy as part of a living-related renal transplant. One gram of intravenous cefazolin was administered perioperatively. The surgery was completed without complication and the remainder of his hospital course was uneventful. Ten days following discharge the patient developed fevers, painful and swollen joints, and a cutaneous eruption overlying his trunk and extremities. There was no evidence of systemic vasculitis. These clinical findings were most consistent with a serum sickness-like reaction. A brief course of corticosteroids and antihistaminergic therapy was initiated, and complete resolution of the patients symptoms followed. The Naranjo probability scale indicated that this adverse drug event was probable.ConclusionSerum sickness-like reaction may be associated with cefazolin therapy.

Background The waiting list for kidney transplantation is long. The creation of “vouchers” for future kidney transplants enables living donation to occur when optimal for the donor and transplantation to occur later, when and if needed by the recipient. Methods The donation of a kidney at a time that is optimal for the donor generates a “voucher” that only a specified recipient may redeem later when needed. The voucher provides the recipient with priority in being matched with a living donor from the end of a future transplantation chain. Besides its use in persons of advancing age with a limited window for donation, vouchers remove a disincentive to kidney donation, namely, a reluctance to donate now lest one’s family member should need a transplant in the future. Results We describe the first three voucher cases, in which advancing age might otherwise have deprived the donors the opportunity to provide a kidney to a family member. These 3 voucher donations functioned in a nondirected fashion and triggered 25 transplants through kidney paired donation across the United States. Conclusions The provision of a voucher to potential recipients whose need for a transplant makes them “chronologically incompatible” with their donors may increase the number of living donor transplants.

Expanded Criteria Living Donors: How Far Can We Go?:

David Serur; Marian Charlton

In an effort to expand the deceased donor pool, transplant centers have accepted expanded criteria donors as appropriate for many of the patients in the deceased donor pool. Translating this into the living donor pool is more complex. One must consider not only the quality of the organ procured but the consequences that the nephrectomy might have on the living donors for the rest of their lives. This review examines the available data on higher risk donors and the appropriateness, or lack thereof, of accepting them as kidney donors.

Background Kidney paired donation chains are initiated by nondirected donors and propagated by donors within the chain of transplants, or chain donors. Objective To compare psychosocial and functional outcomes, and to test coercion, of chain donors in paired exchange versus traditional directed donors who have an established relationship with the recipient. Methods Thirty chain donors from a transplant center who were part of the National Kidney Registry paired exchange program were compared with 34 traditional donors who donated around the same time. Participants completed online surveys: the post-donation section of the Living Donor Expectancies Questionnaire was used to assess psychosocial and functional outcomes 1 to 6 years after donation. A survey to assess coercion was used as well. Results Chain donors and traditional donors were similar in terms of sex, race, age, and time after donation. The 2 groups had similar altruistic motives in donating their kidney, and both types of donors mentioned psychological benefits. No differences were found on questions regarding psychosocial outcomes save for the “quid pro quo scale” (P = .01), which suggested that the traditional donors felt more that the recipients are indebted to them. The 2 groups did not differ significantly in the coercion measure. Pressure to donate and stress of donation were not greater in chain donors than traditional donors (P = .60). Conclusion Kidney donors in kidney paired donation chains do as well as traditional donors psychosocially without any increased tendency toward experiencing coercion.

Is donating a kidney to a friend bad for your marriage

Studies have shown that kidney donation to a spouse has a positive impact on marriage. This study was done to evaluate the impact on marriage when donation occurs to someone other than the spouse. Two groups of donors from our centre who donated around the same period were studied: donation to a spouse (spouse donor (SD)) or to someone other than the spouse (non‐spouse donor (ND)). A survey, the Revised Dyadic Adjustment Scale, was used to evaluate the effect of donation on the marriage. This tool consists of 14 questions that measure how satisfying and stable the relationship is. The results showed equal or better marriage scores in the ND group compared with the SD group. The NDs scored higher on two questions, one regarding agreement or disagreement on career choices (P = 0.05) and the other regarding the frequency of having stimulating exchanges of ideas with ones spouse (P = 0.02). With the highest possible total score of 69, NDs scored 53.4 and SDs scored 47.7 (P = 0.16). Scores of 47 and below indicate marital distress. In one final additional question, 97% of NDs reported ‘no change or good effect’ on the marriage, similar to 91% for SDs (P = 0.46). This is the first study to evaluate the effect of kidney donation on the state of marriage when the spouse is not the recipient. It appears that marriage is not impacted negatively when kidney donation occurs to someone other than the spouse.

Solicited kidney donors: Are they coerced?

David Serur; Gretchen Bretzlaff; Paul J. Christos; Farrah Desrosiers; Marian Charlton

Most non‐directed donors (NDDs) decide to donate on their own and contact the transplant centre directly. Some NDDs decide to donate in response to community solicitation such as newspaper ads or donor drives. We wished to explore whether subtle coercion might be occurring in such NDDs who are part of a larger community. One successful organization in a community in Brooklyn, NY, provides about 50 NDDs per year for recipients within that community. The donors answer ads in local papers and attend donor drives. Herein, we evaluated the physical and emotional outcomes of community‐solicited NDDs in comparison to traditional NDDs who come from varied communities and are not responding to a specific call for donation. An assessment of coercion was used as well.

Patients with asymptomatic kidney stones have a high rate of progression to becoming symptomatic kidney stones when followed for several years. Small kidney stones are often found incidentally on imaging when evaluating patients for kidney donation, and there is a concern that after nephrectomy, the donor may become symptomatic and incur damage to the remaining kidney. We reviewed kidney donors at our institution with asymptomatic stones and surveyed them several years after donation to see if the stones became clinically active.
