[Optimization of hydrodynamic conditions in transurethral resection of benign prostatic hyperplasia].

Water intoxication remains a serious complication of transurethral resection (TUR) occurring more frequently in patients with large-size benign prostatic hyperplasia (BPH) and in those who was operated for more than 1 hour. An advanced irrigation system employing mechanical valve "Floval" and active aspiration provides controlled irrigation of the bladder preventing spontaneous rise of intravesical pressure in conducting TUR in BPH patients.
