Abstract

Introduction: The prolongation of the life of men results in the growing number of people suffering from benign prostatic hyperplasia (BPH). In 2010, BPH concerned more than 200 million men in the whole world, which at that time made up 6% of the population of men at large. Currently, the population of men in the world amounts about three billion six hundred million. The modern surgical treatment of BPH consists of minimally invasive techniques, including laser systems. Aim: Evaluation of the eff ectiveness of photoselective vaporization of the prostate (PVP) on the basis of subjective parameters assessed by patients using IPSS and QoL questionnaires as well as objective parameters obtained from results of urodynamic tests. Material and Methods: Between 2012 and 2015, 120 patients with benign prostatic hyperplasia were included in the study and underwent PVP. Finally, 77 patients were included in the study. In all patients, IPSS and QoL sheets were carried out 1, 6 and 12 months, and urodynamic tests 12 months after the surgical treatment. Results: The statistically signifi cant change in the value of each parameter assessed: decrease in the IPSS, QoL, PVR, Pmax, Pop, the degree of obstruction according to Schäfer and ICS nomogram, and an increase in the values of Qmax and Qave. Conclusions: Photoselective vaporization of the prostate is an eff ective method of therapy in patients with benign prostatic hyperplasia.

Abstract

The paper presents precipitation results from cold thermal water deposits that are the main cause of clogging in absorbent geothermal wells and borehole areas. As a result of physical and chemical analysis, laboratory tests and observation of the operation of a geothermal installation, a new method was developed to prevent the precipitation of sludge from cooled thermal water. The method being a modification of soft acidising was tentatively named as a super soft acidising method
