ABSTRACT
BACKGROUND: Medullary sponge kidney (MSK) disease predisposes patients to recurrent nephrolithiasis, which affects one in every 5000 people in the United States. METHODS: We report a rare case of a pediatric recipient of a living donor MSK transplant and discuss considerations when discussing risks and benefits of accepting MSK allografts for this population. RESULTS: The recipient was admitted due to concerns for nephrolithiasis, hydronephrosis, and urinary tract infection at 1-month post-transplant. The hydronephrosis was resolved by surgical removal of an encrusted ureteral stent; this was followed by supplementation with oral medications to prevent future episodes of nephrolithiasis. The recipient did not have any further episodes after this as seen at a 1-year follow-up. The donor has remained well through this period. CONCLUSIONS: With increasing organ shortages, the use of variety of donors may need to be considered to enlarge the organ pool.

BACKGROUND: Discard rate of Public Health Service Increased Risk (PHS-IR) organs is high despite the absence of worse kidney transplant outcomes. METHODS: We conducted a retrospective, single-center study of PHS-IR kidney offers made to kidney transplant-only potential recipients from 6/2004 to 5/2015. Overall mortality and transplant outcomes between potential recipients were stratified by response to PHS-IR kidney offers. Cox regression and Kaplan-Meier analyses of mortality and allograft failure were performed. RESULTS: A total of 2423 potential recipients were offered a PHS-IR kidney, with 1502 transplanted, with or without a PHS-IR kidney. Predictors of accepting a PHS-IR kidney included higher Estimated Post Transplant Survival (EPTS) score, prior kidney transplant, and lower educational achievement on multivariable analysis (P = 0.025, P = 0.004, P = 0.023). A positive response to a PHS-IR kidney was associated with lower risk of mortality (3.63% vs 11.6%; aHR 0.467, P = 0.0008). PHS-IR kidney recipients had decreased risk of allograft loss compared to non-PHS-IR recipients (P = 0.007), though mortality outcomes were not significantly different based on PHS-IR status (P = 0.38). No transmission of HIV, HBV, or HCV occurred from PHS-IR kidney donors in this cohort. CONCLUSIONS: Efforts must be made to increase awareness of the beneficial outcomes of PHS-IR organs to maximize appropriate donor allocation.

BACKGROUND: Studies have demonstrated the Timed Up and Go Test's (TUGT) ability to forecast postoperative outcomes for several surgical specialties. Evaluations of the TUGT for waitlist and posttransplant outcomes have yet to be examined in kidney transplantation. OBJECTIVE: To assess the prognostic utility of the TUGT and its associations with waitlist and posttransplant outcomes for kidney transplant candidates. DESIGN AND METHODS: Single-center, prospective study of 518 patients who performed TUGT during their transplant evaluation between 9/1/2013-11/30/2014. TUGT times were evaluated as a continuous variable or 3-level discrete categorical variable with TUGT times categorized as long (>9 seconds), average (8-9 seconds), or short (5-8 seconds). RESULTS: Transplanted individuals had shorter TUGT times than those who remained on the waitlist (8.99 vs 9.79 seconds, P < 0.001). Bivariable and multivariable logistic regression showed that after adjusting for age, there was no association between TUGT times and probability of waitlist removal (OR 0.997 [0.814-1.221]), prolonged length of stay posttransplant (OR 1.113 [0.958-1.306] for deceased donor, OR 0.983 [0.757-1.277] for living donor), and 30-day readmissions (OR 0.984 [0.845-1.146] for deceased donor, OR 1.254 [0.976-1.613] for living donor). CONCLUSIONS: The TUGT was not associated with waitlist removal or prolonged hospitalization for kidney transplant candidates. Alternative assessments of global health, such as functional status or frailty, should be considered for evaluation of potential kidney transplant candidates.
