A 64yo man has been waking up in the middle of the night to go to the bathroom. He also had
difficulty in initiating micturition and complains of dribbling. A dx of BPH was made after a
transrectal US guided biopsy and the pt was prepared for a TURP. What electrolyte abnormality
is highly likely due to this surgery?
a. Hypokalemia
b. Hypocalcemia
c. Hyperkalemia
d. Hyponatremia
e. Hypernatremia
answer D
Transurethral resection (TUR) syndrome :
absorption of large volumes of the irrigating
fluid through the open prostatic veins may
result in hyponatraemia and confusion.
