Factors increasing fluid absorption and electrolyte derangement during TURP.

Factors increasing fluid absorption during TURP	Strategies to minimize fluid absorption
Open prostatic sinuses
(i) Weight of tissue resected (used as surrogate marker)	(i) Consider open prostatectomy or HoLEP for >80 g prostate
(ii) Capsular breech	(ii) Avoid deep resection
Lengthy resection
Prostatic sinuses exposed for longer time	Keep resection time under 60 min
High irrigation pressure
(i) Height of irrigation column	(i) Keep irrigation fluid at height of 60 cm
(ii) Small capacity bladder	(ii) Continuous flow resectoscope
Hypotonic irrigant	(i) Use of isotonic irrigant  (ii) Bipolar diathermy
