Metabolic acidemia due to saline absorption during transurethral and transcervical surgery: a report of 2 cases.

Background: The development of endoscopic systems that include bipolar electrocautery has enabled the use of normal saline irrigation in transurethral or transcervical endoscopic surgery. However, excessive saline absorption can cause hyperchloremic metabolic acidosis.

Case Presentation: Patient 1: A 76-year-old man was scheduled for transurethral resection of the prostate with saline irrigation.
