*Purpose: Increased intra-abdominal pressure (IAP) is a common complication among critically ill and post-surgical patients that can cause organ dysfunction. Its prevalence and effects after kidney transplantation are unknown. We aimed to assess the prevalence of increased IAP and its impact on delayed graft function (DGF) in a sample of deceased-donor kidney transplant recipients.
*Methods: Prospective cohort study in a nephrology department of a tertiary referral teaching hospital. IAP was measured every 8h for the first 72h after transplant surgery using the urinary bladder technique (UnoMeter Abdo-Pressure kit). Intra-abdominal hypertension was defined as IAP ≥12 mmHg. DGF was defined as the use of dialysis within 7 days of transplantation.
*Results: 121 patients were included in the study. Mean IAP was 12.6±3.5 mmHg in the first 24h. Demographic, anthropometric and clinical data is summarized in Table 1. IAP was an independent risk factor of DGF in adjusted logistic regression analysis (OR: 1.214; 95%CI 1.072-1.375; P=0.002).

| Day 0 mean IAP, mmHg | 8.3±1.6 | 13.5±3.1 | <0.001 |
*Conclusions: Increased IAP was highly prevalent during the first hours after renal transplantation and was associated with higher rates of DGF. Routine IAP measurement should be considered after transplantation to facilitate early recognition of complications and institution of appropriate therapeutic interventions.
