The importance of continuous pump suction in TUR hydraulic hemostasis.
An intravesicoprostatic hydrostatic pressure below 10 mm Hg maintains normal anatomy and physiology of the muscular and vascular prostatic structures by continuous pump suction. An increase of the hydrostatic intravesicoprostatic pressure above 10 mm Hg produces a distortion in the musculature of the prostate, especially at the true capsule, opening the cut vessels, making possible the absorption of the irrigant free of electrolytes (TUR syndrome). A low hydrostatic intravesicoprostatic pressure permits the compression of cut vessels by the inflow hydraulic pressure of 90 cm H2O achieving hydraulic hemostasis during TURP reducing the bleeding and operative time by more than 50% and making hemostasis easier. In our last 400 TURs, blood transfusions have been unnecessary. Less electrocoagulation is required, resulting in a more rapid recovery.
