The prevalence of end-stage kidney disease (ESKD) in Singapore remains high and continues to rise. We continue to face major challenges in containing the rising incidence of ESKD and providing sustainable kidney replacement therapy. Our cost projections provide an insight into the present and future, urging a call to action to augment existing initiatives to address the emergent issues.

Objective: To investigate the prognosis factors for death within 90 days after discharge in patients with acute kidney injury(AKI) treated requiring continuous renal replacement therapy(CRRT) undergoing surgery for acute Standford type A aortic dissection. Methods: The clinic data of 126 patients undergoing CRRT for postoperative AKI after acute type A aortic dissection surgery in the Center for Cardiac Intensive Care, Beijing Anzhen Hospital from July 2016 to February 2019 were analyzed retrospectively. There were 83 males and 43 females, aging (52.9±11.2) years(range: 25 to 70 years). The patients' demographic characteristics, disease-related information, perioperative data, laboratory indexes during CRRT, complications, and survival information within 90 days after discharge were recorded. Independent prognosis factors for death within 90 days of discharge were determined by Kaplan-Meier survival analysis, univariate and multifactorial Cox regression analysis. Results: Totally 57 of 126 patients(45.2%) died over the first 90 days after discharge. Kaplan-Meier survival analysis and univariate Cox regression analysis showed that there were significant differences between the non-survival and survival group including ≥65 years old, high lactate values 12 hours after CRRT, pulmonary infection, liver dysfunction, presence of permanent neurological complications, and postoperative ejection fraction(EF)<45%. Multifactorial Cox regression analysis revealed that ≥65 years old(HR=2.14, 95%CI: 1.09 to 4.21, P=0.03), high lactate values 12 hours after CRRT(HR=1.13, 95%CI: 1.06 to 1.20, P=0.01) and postoperative EF<45%(HR=2.21, 95%CI: 1.09 to 4.51, P=0.03) were independent prognosis factors for patients' death within 90 days after hospital discharge. Conclusions: ≥65 years old, high lactate values 12 hours after CRRT and postoperative EF<45% are independent prognosis factors for death within 90 days after discharge in patients undergoing CRRT for AKI after acute type A aortic dissection surgery. Proper identification and management of prognosis factors could be beneficial to improve patients' outcomes.

BACKGROUND:
Acute kidney injury (AKI) is a common and serious complication following lung transplantation (LTx), and it is associated with high mortality and morbidity. This study assessed the incidence of AKI after LTx and analyzed the associated perioperative factors and clinical outcomes.
METHODS:
This retrospective study included all adult LTx recipients at the China-Japan Friendship Hospital in Beijing between March 2017 and December 2019. The outcomes were AKI incidence, risk factors, mortality, and kidney recovery. Multivariate analysis was performed to identify independent risk factors. Survival analysis was presented using the Kaplan-Meier curves.
RESULTS:
AKI occurred in 137 of the 191 patients (71.7%), with transient AKI in 43 (22.5%) and persistent AKI in 94 (49.2%). AKI stage 1 occurred in 27/191 (14.1%), stage 2 in 46/191 (24.1%), and stage 3 in 64/191 (33.5%) of the AKI patients. Renal replacement therapy (RRT) was administered to 35/191 (18.3%) of the patients. Male sex, older age, mechanical ventilation (MV), severe hypotension, septic shock, multiple organ dysfunction (MODS), prolonged extracorporeal membrane oxygenation (ECMO), reintubation, and nephrotoxic agents were associated with AKI (P < 0.050). Persistent AKI was independently associated with pre-operative pulmonary hypertension, severe hypotension, post-operative MODS, and nephrotoxic agents. Severe hypotension, septic shock, MODS, reintubation, prolonged MV, and ECMO during or after LTx were related to severe AKI (stage 3) (P < 0.050). Patients with persistent and severe AKI had a significantly longer duration of MV, longer duration in the intensive care unit (ICU), worse downstream kidney function, and reduced survival (P < 0.050).
CONCLUSIONS
AKI is common after LTx, but the pathogenic mechanism of AKI is complicated, and prerenal causes are important. Persistent and severe AKI were associated with poor short- and long-term kidney function and reduced survival in LTx patients.

OBJECTIVETo analyze the preoperative risk factors on liver transplant recipients with acute renal failure(ARF), and to evaluate renal replacement therapy (RRT) as a transitonary therapy before liver transplantation.
METHODSLiver transplant recipients with acute renal failure treated with renal replacement therapy between January 1st, 2001 and January 1st, 2008 in our center were retrospected. Clinical characteristics, the kinds of RRT and prognosis were analyzed; Logistic regression was applied to analyze the parameters that can forecast the motality of the liver transplant recipients with acute renal failure.
RESULTSOf the patients who received RRT, 30% survived to liver transplantation, 67.5% died while waiting for liver transplantation. The dead had a higher multiple organ dysfunction score (MODS), and lower mean arterial pressure than those survived to liver transplantation. There was no significant difference in the duration of RRT between continuous renal replacement therapy (CRRT) patients and hemodialysis patients. CRRT patients had a higher MODS, lower mean arterial pressure, lower serum creatinine than hemodialysis patients. Lower mean arterial pressure was statistically associated with higher risk of mortality.
CONCLUSIONThough mortality was high, RRT helps part (30%) of patients survive to liver transplantation. Therefore, considering the high mortality without transplantation, RRT is acceptable for liver transplant recipients with ARF.

Holmium laser lithotripsy (HLL) is one of the common surgical methods for urolithiasis. It causes minor surgical trauma, but complications are not rare. Extracorporeal membrane oxygenation (ECMO) treatment of sepsis is common, but venoarterial (VA)-ECMO treatment of urosepsis has not been reported yet. In this article, we reported a 67-year-old female patient with refractory septic shock caused by HLL under percutaneous nephroscope, involving breathing, heart, kidney and other organs, and organs support treatment was ineffective for the patient. Finally, we successfully treated the patient under VA-ECMO with continuous renal replacement therapy (CRRT). Combined ECMO and CRRT may provide a solution for addressing refractory sepsis. Here we present the case and review relevant literature, so as to provide a treatment strategy for patients with refractory urogenic sepsis and to reduce the mortality rate.
