“…Torrecilla Ortiz et al [17] suggested that even if stones were found in a cadaveric donor kidney, this should not be a reason to refuse the graft, as it could be effectively treated through appropriate endo-urological interventions. More recently, Henderickx et al [18] reported successful kidney stone removal by performing back-table endoscopy in a renal allograft. In our study, two stones originating from the donor kidney were effectively treated using ESWL and PCNL, respectively.…”

Background and Objectives: Urolithiasis occurrence is uncommon in kidney transplantation patients, though it has serious implications, including acute kidney injury in the transplanted kidney. This study investigates the leading causes of urolithiasis in kidney transplantation patients, the diagnostic process, and the outcomes of multimodal management. Materials and Methods: Data collection spanned from January 1997 to December 2021, involving kidney transplantation patients with urolithiasis from the database of the Korean Society of Endourology and Robotics (KSER) research committee. Analysis encompassed factors triggering urolithiasis, the diagnostic process, stone attributes, treatment methods, and outcomes. Results: Our analysis included 58 kidney transplantation patients with urolithiasis from eight medical centers. Of these patients, 37 were male and 4 had previous urolithiasis diagnoses. The mean age was 59.09 ± 10.70 years, with a mean duration from kidney transplantation to diagnosis of 76.26 ± 183.14 months. The most frequent method of stone detection was through asymptomatic routine check-ups (54.7%). Among the 58 patients, 51 underwent stone treatment. Notably, 95.3% of patients with ureter stones received treatment, a significantly higher rate than the 66.7% of patients with renal stones (p = 0.010). Success rates showed no significant differences between renal (70%) and ureter stone (78.0%) groups (p = 0.881). Conclusions: Urolithiasis in transplanted kidneys constitutes an acute condition requiring emergency intervention. Endo-urological interventions are effective for kidney transplantation patients with urolithiasis. To ensure prevention and early detection, diligent follow-up and routine imaging tests are necessary.

ObjectivesTo analyse the presentation, management and long‐term outcomes of renal transplant patients who formed kidney stones in their allograft. The secondary aim was to identify risk factors for stone formation in this cohort.Materials and MethodsPatient information from an institutional renal transplant database was used to identify individuals who both did and did not form kidney stones following renal transplantation. Computerized tomography (CT) imaging was used to make the diagnosis of kidney stones and measure stone size. Age‐ and gender‐matched controls never forming a stone in their allograft were used for comparative analysis to identify risk factors for stone formation in transplant patients.ResultsA total of 8835 transplant patients were included in the study, of which 128 (1.4%) formed a kidney stone in their allograft after surgery. The mean time to kidney stone identification was 6.2 years, and the mean number of stones formed was 1.7, with a mean maximum size dimension on a CT scan of 5.7 mm per stone. A total of 26 patients were subjected to stone‐removing procedures, the most common being ureteroscopy (42.3%). The primary intervention failed in eight patients requiring a secondary intervention, and percutaneous nephrolithotomy (PCNL) had the lowest success rate (60%). A total of 164 controls were identified. In comparison to controls, stone formers had lower serum calcium (p = 0.008), lower estimated glomerular filtration rates (p = 0.019), higher lymphocyte counts (p = 0.021) and greater rate of urinary tract infection (p = 0.003). Graft failure rates were the same (p = 0.524), but time to graft failure was significantly longer in stone patients compared with controls (p = 0.008).ConclusionsThe rate of stone formation is low in transplant patients. Success rates for stone treatment vary based on the surgery selected, with PCNL being the worst. Graft survival rates were equivocal, but survival time was better in stone patients. Our analysis calls for further investigation of this important topic.
