Abstract
Background and objectives: Patients undergoing radical prostatectomy are at increased risk of
Acute Kidney Injury (AKI) because of intraoperative bleeding, obstructive uropathy, and older
age. Neutrophil Gelatinase-Associated Lipocalin (NGAL) may become important for diagnosis
of postoperative AKI after urogenital oncosurgery. The objective of this study was to evaluate
and compare the efficacy of NGAL as a predictor of AKI diagnosis in patients who underwent
Retropubic Radical Prostatectomy (RRP) and Robot-Assisted Laparoscopic Prostatectomy (RALP)
for prostate cancer.
Methods: We included 66 patients who underwent RRP (n = 32) or RALP (n = 34) in this prospective, comparative, nonrandomized study. Patients’ demographic data, duration of surgery and
anesthesia, amount of blood products, vasopressor therapy, intraoperative blood loss, fluid
administration, length of hospital stay, creatinine, and plasma NGAL levels were recorded.
Results: Intraoperative blood loss, crystalloid fluid administration, and length of hospital stay
were significantly shorter in RALP. There was no statistically significant difference between the
groups in terms of intraoperative blood transfusion. Postoperative creatinine and plasma NGAL
levels were increased in both groups. The 6-h NGAL levels were higher in RRP (p = 0.026). The
incidence of AKI was 28.12% in RRP and 26.05% in RALP, respectively. The NGAL level at 6 hours
was more sensitive in the early diagnosis of AKI in RALP.
