Background: Ureteral stents are thought to prevent or help identify ureteral injuries. Studies suggesting that ureteral stents increase the risk of postoperative acute kidney injury show inconsistent conclusions. The large ureteral stenting volume at our institution provided a unique opportunity for granular analysis not previously reported.
Objective: To determine whether prophylactic ureteral stenting at colorectal surgery increases acute kidney injury.
Design: Retrospective analysis of colorectal operations with prophylactic ureteral stents was compared to operations without stents. Adjusted analysis was performed with inverse probability treatment weighting.
Settings: Single institution enhanced recovery colorectal surgery service.
Patients: Prospective institutional database between July 1, 2018, and December 31, 2021.
Main Outcome Measure: The primary outcome was acute kidney injury, defined as increase in creatinine ≥0. 3 mg/dL (definition 1) and 1.5-fold increase in creatinine (definition 2) within 48 hours postoperatively.
Results: There were 410 patients in the study population: 310 patients in the stent group and 100 in the no-stent group. There were 8 operative ureteral injuries: 4 (1.29%) in the stent group and 4 (4.0%) in the no-stent group ( p = 0.103). Unadjusted analysis revealed no significant difference in acute kidney injury between groups. After adjustment, there was still no significant difference in acute kidney injury between groups when defined as definition 1 (no-stent 23.76% vs stent 26.19%, p = 0.745) and as definition 2 (no-stent 15.86% vs stent 14.8%, p = 0.867). Subgroup analysis showed that lighted stents were associated with significantly more acute kidney injury than no-stent patients when defined as definition 1 ( p = 0.017) but not when defined as definition 2 ( p = 0.311).
Limitations: Single-institution results may not be generalizable.
Conclusion: Prophylactic ureteral stenting does not increase the risk of acute kidney injury for patients undergoing enhanced recovery colorectal surgery, although caution and further study may be warranted for lighted stents. Studies further examining contrasting roles of ureter stenting and imaging in open and minimally invasive colorectal surgery are warranted. See Video Abstract.
Los Stents Ureterales No Aumentan El Riesgo De Lesin Renal Aguda Despus De La Ciruga Colorectal: ANTECEDENTES:Se cree que los stents ureterales previenen o ayudan a identificar las lesiones ureterales. Los estudios que sugieren que los stents ureterales aumentan el riesgo de lesión renal aguda post operatoria muestran conclusiones contradictorias. El gran volumen de endoprótesis ureterales en nuestra institución brindó una oportunidad única para el análisis granular que no se informó anteriormente.OBJETIVO:Determinar si la colocación de stent ureteral profiláctico en cirugía colorrectal aumenta el daño renal agudo.DISEÑO:El análisis retrospectivo de operaciones colorrectales con stents ureterales profilácticos se comparó con operaciones sin stents. El análisis ajustado se realizó con ponderación de tratamiento de probabilidad inversa.AJUSTES:Cirugía colorrectal de recuperación mejorada de una sola instituciónPACIENTES:Base de datos institucional prospectiva entre el 01/07/2018 y el 31/12/2021.MEDIDA DE RESULTADO PRINCIPAL:El resultado primario fue la lesión renal aguda definida como un aumento en la creatinina ≥ 0,3 mg/dL (Definición n.° 1) y un aumento de 1,5 veces en la creatinina (Definición n.° 2) dentro de las 48 horas posteriores a la operación.RESULTADOS:Hubo 410 pacientes en la población de estudio: 310 pacientes en el grupo Stent y 100 en el grupo No-Stent. Hubo 8 lesiones ureterales operatorias, 4 (1,29%) en el grupo Stent y 4 (4,0%) en el grupo No-Stent (p = 0,103). El análisis no ajustado no reveló diferencias significativas en la lesión renal aguda entre los grupos. Después del ajuste, todavía no hubo una diferencia significativa en la lesión renal aguda entre los grupos cuando se definió como Definición n.º 1 (sin stent 23,76 % frente a stent 26,19 %, p = 0,745) y por definición n.º 2 (sin stent 15,86 % frente a stent 14,8 %, p = 0,867). El análisis de sub grupos mostró que los stents iluminados se asociaron con una lesión renal aguda significativamente mayor que los pacientes sin stent cuando se definieron como Definición n.º 1 (p = 0,017), pero no cuando se los definió como Definición n.º 2 (p = 0,311).LIMITACIONES:Los resultados de una sola institución pueden no ser generalizables.CONCLUSIÓN:La colocación profiláctica de endoprótesis ureterales no aumenta el riesgo de lesión renal aguda en pacientes que se someten a cirugía colorrectal de recuperación mejorada, aunque es posible que se requiera precaución y estudios adicionales para las endoprótesis iluminadas. Se justifican estudios que examinen más a fondo las funciones contrastantes de la colocación de stents de uréter y las imágenes en la cirugía colorrectal abierta y mínimamente invasiva.

Mitochondrial dysfunction is a crucial event in acute kidney injury (AKI), leading to a metabolic shift toward glycolysis and increased lactate production. Lactylation, a posttranslational modification derived from lactate, plays a significant role in various cellular processes, yet its implications in AKI remain underexplored. Here, a marked increase in lactate levels and pan-Kla levels are observed in kidney tissue from AKI patients and mice, with pronounced lactylation activity in injured proximal tubular cells identified by single-cell RNA sequencing.

Congenital thrombotic thrombocytopenic purpura (cTTP), which is associated with mutations in the gene for a disintegrin and metalloproteinase with a thrombospondin type 1 motif member 13 (ADAMTS13), is a chronic and lifelong disease. The clinical course is variable. Regularly using ADAMTS13-containing products such as fresh frozen plasma (FFP) for long-term prophylaxis is the most important treatment to prevent thrombotic microangiopathy (TMA) episodes.

Objective: Chronic obstructive pulmonary disease (COPD) and chronic kidney disease (CKD) are significant global health issues with a well-established association between the two. This study aims to assess the risk of developing CKD in patients with COPD through systematic review and meta-analysis, and to explore the impact of CKD on the prognosis of COPD patients.
Methods: A total of 23 studies were included in the analysis, comprising 11 studies on the risk of CKD in patients with COPD, 6 studies on the impact of CKD on the short-term all-cause mortality risk of patients with acute exacerbation of COPD (AECOPD), and 6 studies on the impact of CKD on the long-term all-cause mortality risk of COPD patients.

Rationale: Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerulonephritis caused by extra-renal infectious diseases. There has been an important shift in epidemiology in recent years, with a significant proportion of adults affected. The incidence of IRGN is higher amongst Indigenous populations and especially in those with multiple comorbidities.

Leptospirosis, an infection caused by the spirochete Leptospira and commonly attributed to the underdeveloped world, is frequently under-diagnosed in the United States. This report discusses the case of a 79-year-old male with no significant medical history who presented to the ED with recurrent falls. Initial laboratory results demonstrated severe acute kidney injury, hyperbilirubinemia, and thrombocytopenia.
