Litiasis urinaria en el donante cadavérico: respuestas a la penumbra urológica desde un análisis bibliométrico

The clinical literature about the implications of urolithiasis in the process of kidney donation/transplantation (KTx) from deceased donors is scarce. Objectives: To expose the current state of bibliographic production and the clinical implications of urolithiasis in the process of kidney donation/transplantation focus on cadaveric donor grafts. Methods: We performed a bibliometric analysis based on a systematic review of the literature in Medline, Embase, SciELO, Cochrane Central, Google Scholar and Web of Science using combinations (OR, AND) of MesH terms: “urolithiasis”,“kidney calculi”,“ureteral calculi”, “tissue and organ procurement”, “brain death”, “living donors” and “kidney transplantation”. The search was limited to primary articles, systematic reviews or meta-analyses performed in humans published between 2000-2022. Results: Twenty-three articles were included for analysis; 95.6% of the bibliographic production was published in English, 26% were published into quartile 1 journals. One third of the references were focused on cadaveric donors. The information obtained concludes that presence of urolithiasis in the kidney graft is not an absolute contraindication for KTx and proposes the ex vivo surgical management of urolithiasis during the bench surgery for stones > 4 mm and to proceed with KTx and then follow-up for kidney grafts with stones < 4 mm. Conclusions: The scientific production related to urolithiasis and kidney donation/transplantation is limited. The literature available concludes that incidental kidney stones in kidney grafts should not be considered an absolute contraindication for KTx. Ex vivo surgical management of urolithiasis is a feasible and safe prior to KTx.
