[Use of local baroimpulse therapy in the treatment of patients with chronic abacterial prostatitis / chronic pelvic pain syndrome and erectile dysfunction].

AIM: To study the efficiency of local baroimpulse therapy (BIT) in the complex treatment of patients with chronic abacterial prostatitis/chronic pelvic pain syndrome (CP/CPPS) and erectile dysfunction (ED). MATERIALS AND METHODS: A total of 112 men with confirmed diagnosis of CP/CPPS and ED, who received drug therapy according to the standards and guidelines were included in the study. In the main group (n=68) all patients additionally received local BIT in the form of rectal pneumovibromassage (PVM) of the prostate (totally, 10 procedures). In the control group (n=44) only standard treatment was provided. The efficiency of therapy was assessed based on the complex clinical examination, laboratory tests and imaging methods. RESULTS: At the visit 2 (1 month after the start of therapy) there were significant differences in clinical (resolution of symptoms of CP/CPPS and improvement of erectile function), laboratory and imaging criteria between 2 groups. The rectal PVM using apparatus MKV-01 "Inavita" resulted in decrease the activity of inflammation process and levels of pro-inflammatory cytokines, increase of flow rate and intraprostatic blood flow. According to the analysis of long-term results, after 6 months of therapy the remission was seen in the most of patients in the main group (79.4%), which was 40.8% higher than in the control group. CONCLUSION: The use of local BIT by mean of rectal PVM allows to increase efficiency of complex treatment of patients with CP/CPPS and ED.

[Methods for training of robot-assisted radical prostatectomy]. / Metody obucheniia robot-assistirovannoi radikal'noi prostatéktomii.

Robotic surgery is a future method of minimal invasive surgery. Robot-assisted radical prostatectomy (RARP) is a common method of surgical treatment of prostate cancer. Due to significant differences of the surgical technique of RARP compared to open or laparoscopic radical prostatectomy (LRP) new methods of training are needed. At the moment there are many opinions how to train physicians best. Which model is the most effective one remains nowadays controversial. OBJECTIVE: Analyze currently available data of training methods of RARP. Determine the most effective training model and evaluate its advantages and disadvantages. Establish a standardized plan and criteria for proper training and certification of the entire surgical team. MATERIAL AND METHODS: Literature review based on PubMed database, Web of Science and Scopus by keywords: robot-assisted radical prostatectomy, training of robot-assisted prostatectomy, training in robot-assisted operations, a learning curve of robot-assisted prostatectomy, virtual reality simulators (VR-simulators) in surgery. RESULTS: According to the literature in average 18 to 45 procedures are required for a surgeon to achieve the plateau of the learning curve of the RARP. Parallel training, pre-operative warm-up and the use of virtual reality simulators (VR-simulators) can significantly increase the learning curve. There are many described models of RARP training. CONCLUSIONS: The absence of accepted criteria of evaluation of the learning curve does not allow to use this parameter as a guide for the surgeon's experience. Proper training of robotic surgeons is necessary and requires new methods of training. There are different types of training programs. In our opinion the most effective training program is when a surgeon observes the performance of tasks or any steps of operation on the VR-simulator, then he performs them and analyzes mistakes by video recording. Then the surgeon observes real operations and performs some steps of the operation which are already leant on the simulator under supervision of the mentor and analyzes mistakes by video recording. Thus, mastering first the simple stages under supervision of a mentor, the surgeon effectively adopts the surgical experience from him. It is necessary to train not only the surgeons but also the entire surgical team.

[The role of waterjet dissection in improving erectile function and continence after nerve-sparing prostatectomy].

INTRODUCTION: Erectile dysfunction (ED) and urinary incontinence (UI) following radical prostatectomy (RP) adversely impact patients psycho-emotional status reducing the quality of life and treatment satisfaction. AIM: To investigate the rates of regaining continence and erectile function (EF) after nerve-sparing radical retropubic prostatectomy (NS-RRP) and nerve-sparing laparoscopic radical prostatectomy (NS-LRP) in the early postoperative period. MATERIALS AND METHODS: The study comprised 116 patients who preserved sexual activity and the ability to have sex. 64 patients underwent standard resection of NVB (34 RRP and 30 LRP) and in 52 patients the NVB resection was performed using a waterjet dissector (WD) (30 RRP and 22 LRP). All operations were performed by one surgeon with the experience of over 350 RRP and 150 LRP. The study patients had low and moderate risk prostate cancer, according to DAmico risk classification. RESULTS: Our study findings showed that patients who underwent the WD of NVB had significantly greater IIEF-5 scores (by 2.8 scores) at 8 weeks than after the standard NS-RP. After 6 month follow-up the scores increased by 3.5 points. Patients who underwent NS-RP + WD achieved a successful sexual intercourse 3 months after surgery (regardless of the use of PDE5 inhibitors). In the group of patients who underwent standard NS-RP, it took a longer time to achieve a successful sexual intercourse. Sixty-seven percent of patients who underwent NS-RP + WD were fully continent at one month follow-up after removal of urethral catheter, while most patients treated with standard NS-RP (41%) had mild stress UI. After 3 months follow-up, among patients who underwent NS-RP + WD only one patient had mild stress UI and the vast majority (95%) of patients were fully continent. At 6 months after removal of the urethral catheter there were no significant differences between the groups in regaining urinary continence. CONCLUSIONS: Waterjet dissection of NVB significantly improves patients postoperative quality of life due to early recovery of urinary continence and EF.
