Endoscopic Treatment of Prostatic Hyperplasia in Elderly Patients: A Comparative Analysis of Resection and Enucleation Technique

Abstract

Introduction. The pharmacological market, which is rapidly developing, as well as the appearance of combined forms of drugs, determine the trend in the conservative treatment of patients with symptoms of the lower urinary tract due to benign prostatic hyperplasia (BPH). However, simultaneous administration of drugs from several drug groups, by the patients, who are burdened with concomitant diseases (cardiovascular disease, diabetes) in certain cases, makes surgical treatment of BPH preferable and sometimes the only possible option. In this instance, the doctor’s task is to choose the optimal method of surgery that minimizes the risks of complications and provides a long-term clinical effect. The actively developing technique of endoscopic enucleation of prostate corresponds to the current needs. Various types of energies, which have appeared lately in urological practice for enucleation of the prostate, have become an attractive alternative to transurethral resection of the prostate (TURP). The introduction of a bipolar technology into clinical practice has allowed to significantly expand the use of operations among elderly patients with comorbidities. Laser endourology has gone further in reducing the risks of possible complications. Currently we are witnessing a lack of research, which compares the use of modern methods with bipolar TURP (B-TURP) in elderly patients, i.e. groups with a high risk of intraoperative & postoperative complications.Purpose of the study. To compare the results of various types of BPH endoscopic surgical treatment in elderly patients (> 60 years old).Materials and methods. The study included patients who underwent three different operations treating BPH (B-TURP, B-TUEP, HoLEP) from October 2017 to September 2018. The criteria for inclusion in the study were as follows: the presence of moderate or severe obstructive symptoms of the lower urinary tract, prostate volume > 40 cm3, maximum urine flow <15 ml/s. Exclusion criteria were as follows: the presence of cystostomy drainage, the presence of the oncological process in urinary tract, active inflammatory process of urogenital system, earlier received surgical interventions on the organs of the urinary system. Each group of patients has been assessed on following criteria: International Prostate Symptom Score (IPSS and QoL), international index of erectile function (IIEF-5), the dynamics of postoperative changes in prostate specific antigen (PSA), maximum flow of urine, postvoid residual urine volume, intraoperative and postoperative parameters.Results. 190 patients operated during the year were examined in the current study. Duration of operation, extent of resection, time of postoperative catheterization and duration of hospital stay rates were significantly lower in the HoLEP group. There have been no cases of complications above the 3 level by the Clavien‒Dindo scale.Conclusions. HoLEP is the preferred method of surgical treatment of prostatic hyperplasia over 40 cm3 in terms of surgical safety, efficacy, and the duration of the patient’s recovery period. This method can serve as an alternative to electrosurgical techniques in elderly patients.
