Factors increasing fluid absorption during TURPStrategies 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 timeKeep 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
