Metabolic and Clinical Effects of Hyperchloremia During HoLEP Surgery.

Evaluation of the Metabolic and Clinical Effects of Intraoperative Hyperchloremia in Holmium Laser Enucleation of Prostate (HoLEP) Surgery.

This study aims to evaluate the changes between preoperative and postoperative serum chloride levels in patients undergoing HoLEP surgery and to investigate the metabolic and clinical effects of this change. The study is observational, and no additional interventions will be performed.

Although isotonic irrigation fluids used in HoLEP surgery reduce the risk of hyponatremia associated with TUR syndrome, high-volume fluid absorption may lead to hyperchloremia and subsequent metabolic acidosis. This prospective, observational, single-center study, conducted at Ankara Bilkent City Hospital, aims to identify early markers of this condition to optimize perioperative management.

Inclusion Criteria:

• Patients scheduled for elective HoLEP surgery.
• Patients providing written informed consent

Exclusion Criteria:

• Preoperative metabolic acidosis.
• Advanced renal failure.
• Emergency surgery.
• Missing data.
