[Transurethral electroresection of prostatic adenoma under transrectal ultrasonic control]

Abstract

The aim of the study was to improve the results of transurethral prostatic resection (TUPR) by introduction of intraoperative transrectal ultrasonic investigation (TRUSI) and to determine topographic-anatomic features of the prostate, intraorgan relations of adenomatous nodes and surgical prostatic capsule on-line in TUPR. A total of 64 patients with prostatic adenoma (PA) of the second degree aged 52-79 participated in the study. All of them have undergone TUPR. The patients were divided into two study groups (15 patients with volume of the prostate 36.5-78.6 cm3 and 17 patients with prostate size 80-4-141.2 cm3) in which TRUSI was performed and two control groups (n = 14, size 34.9 to 79.2 cm3 and n = 18, size 81.7-130.8 cm3, respectively) who have not undergone intraoperative TRUSI. PA clinical symptoms were similar in all the groups. Intraoperative TRUSI was conducted in 3 stages (in the beginning, middle and end of surgery) in two planes--transverse and sagittal. Postoperative complications required repeated endoscopic interventions in 2 and 4 patients of groups 2, 3 and 4, respectively. Control TRUSI on day 7 after TUPR registered mean volume of the prostate to be 19.3 +/- 1.4 cm3 in group 1, 39.8 +/- 2.1 cm3 in group 2, 28.1 +/- 1.6 cm3 in group 3, 47.7 +/- 3.2 cm3 in group 4. Maximal flow rate 1 month after TUPR was, on the average, 21.4 +/- 1.4 ml/s, 18.8 +/- 1.1 ml/s, 18.3 +/- 1.6 ml/s and 15.5 +/- 1.2 ml/s in groups 1, 2, 3 and 4, respectively. Thus, intraoperative TRUSI provides information which helps the surgeon to orient in the course of surgery and minimize the threat of perforation of the prostatic capsule; minimizes intraoperative complications and enhances efficacy of radical transurethral electroresection of prostatic hyperplasia improving long-term outcomes of the operation.
