Hydraulic Hemostasis in Transurethral Resection of the Prostate Using the Iglesias Continuous Suction Resectoscope

Abstract

An intravesicoprostatic hydrostatic pressure less than 10 mm. Hg maintains normal anatomy and physiology of the muscular and vascular prostatic structures. An increase in hydrostatic intravesicoprostatic pressure to more than 10 mm. Hg produces a distortion in the musculature of the prostate, especially at the true capsule, opening the cut vessels and making possible the absorption of the irrigant free of electrolytes (transurethral resection syndrome). A low hydrostatic intravesicoprostatic pressure permits the compression of cut vessels by the inflow hydraulic pressure of 90 cm. water, achieving hydraulic hemostasis during transurethral resection of the prostate. Less electrocoagulation is necessary, resulting in more rapid patient recovery.
