Acute Kidney Injury and Its Impact on Renal Prognosis after Robot-Assisted Laparoscopic Radical Prostatectomy.

BACKGROUND This study assessed the incidence and impact of acute kidney injury (AKI) on renal prognosis in patients who underwent robot-assisted laparoscopic radical prostatectomy (RARP). METHODS Medical records of 305 patients treated with RARP were retrospectively reviewed. The patients with postoperative AKIs were dichotomized into early AKI (immediately after surgery) and late AKI (1-7 days after surgery). The impact of AKIs and their risk factors were statistically assessed. RESULTS Early and late AKI were observed in 143 (46.9%) and 12 (3.9%) patients, respectively. Hypertension and console time were independent risk factors for early AKI. Among the patients with preoperative eGFR ≥60 mL/min, the eGFR decline 12 months after surgery was significantly greater in patients with early AKI than that without early AKI (-6.8 vs -3.2 mL/min, P = .02). CONCLUSIONS Approximately half of patients developed early AKI after RARP. The patients with early AKI had reduced renal function 12 months after surgery.
