Perioperative Serum Creatinine Change and Delayed Urologic Complications Following Total Laparoscopic Hysterectomy for Benign Indications.

Abstract

Objectives:The objective of the study was to investigate the association between perioperative serum creatinine change and delayed urologic complications following total laparoscopic hysterectomy (TLH) for benign indications.Materials and Methods:A total of 510 cases (503 cases without delayed urologic injuries and 7 cases with delayed urologic injuries) in which TLH was performed for benign indications were retrospectively reviewed. The patient characteristics and surgical outcomes were compared between patients with and without delayed urologic injuries. Laboratory markers (serum creatinine level at the preoperative and postoperative periods, white blood cell [WBC] ratio, and C-reactive protein [CRP] ratio) were analyzed to evaluate the diagnostic value of these laboratory markers.Results:There were no statistically significant differences in age, parity, body mass index, the presence of diabetes mellitus, preoperative GnRH agonist use, previous history of abdominal surgery or the performance of adnexal surgery, ASRM score, the presence of cul-de-sac obliteration, operative time, blood loss or weight of the resected specimens between the two groups. The proportions of patients who showed an elevated creatinine level on postoperative day 1 was significantly higher in the delayed urologic injury group (9.9% vs. 57%, P < 0.001). The combination of the three laboratory markers yielded an area under the ROC curve value of 0.75 (95% confidence interval, 0.491–1) in the detection of delayed urologic injuries.Conclusion:A change in the serum creatine level over baseline after surgery may indicate the possibility of urologic injuries. The combination of creatinine change and other factors, such as WBC or CRP would be helpful for detecting urologic complications after TLH.
