A rare complication of transurethral resection: Transient Blindness

Transient blindness is an extremely rare complication of transurethral resection (TUR) syndrome, which is a well-known complication recognized by urologists and anesthesiologists. TUR syndrome arises from the intravascular absorption of hypotonic fluids during the procedure. In this case report, an 80-year-old male patient experienced transient blindness after undergoing transurethral resection of the prostate. The patient's medical history included hypertension, lung cancer in remission, and paroxysmal atrial fibrillation. The surgery was performed under spinal anesthesia. During the procedure, the patient was found to be blind. The patient's postoperative blood samples revealed elevated plasma glycine levels, which is a known risk factor for TUR syndrome. The patient's visual impairment began to improve without further intervention. This case report highlights the importance of considering the patient's medical history and the potential risks associated with TUR syndrome.
