[Comparison of the effectiveness of electrovaporisation, vaporesection and electroresection in the treatment of obstructive symptoms in patients with benign prostate hyperplasia].

Objectives: The aim of this study is the comparison of the efficacy of classical electroresection of the prostate (TURP) and its modern modifications--electrovaporisation (EVAP) and vaporesection (TUVRP) in the treatment of patients with benign prostate hyperplasia (BPH).

Material And Methods: 96 patients were operated on because of BPH. In 31 patients we performed TURP (group I), in 34--EVAP (group II) and in 31--TUVRP (group III). On follow up 1, 3, 6 months post operation we evaluated maximal urine flow (Qmax) and postvoid residual urine (PVR) and compared them to preoperation values.

Results: Mean preoperative values were: 8.98 ml/s and 116.76 ml (group I); 8.64 ml/s and 121.36 ml (group II) and 8.69 ml/s and 112.50 ml (group III). In all patients after 1 month follow up Qmax raised almost twice and after 6 months mean values were respectively in groups I, II, III: 21.62 ml/s; 20.79 ml/s; 22.56 ml/s. PVR diminished in 6 months follow up and mean values were respectively 14.61 ml; 15 ml; 11.25 ml. Differences in these results were of no statistical value.

Conclusions: The efficacy of TURP, EVAP and TUVRP in the treatment of BPH is comparable. EVAP and TUVRP also diminished risk of intraoperative bleeding.
