[The correlation of PSA-nadir PS recurrence after total HIFU-ablation in patients with localized prostate cancer].

OBJECTIVE: To study the survival rate of patients without biochemical recurrence according to the Stuttgart and Phoenix criteria in terms of their correlation with four different PSA nadir values as predictors of clinical recurrence in patients with localized prostate cancer who underwent total HIFU prostate ablation. MATERIAL AND METHODS: The object of the study was patients with morphologically proven localized RP by biopsy results, who were treated with prostate cancer by HIFU ablation on the Ablatherm Integrated Imaging apparatus (EDAP TMS, France). The study included 658 patients in whom HIFU ablation was used as primary treatment of localized prostate cancer (stages T1 - T2) without previous use of other methods (hormonal, radiation therapy) For the analysis, a continuous sample of patients was selected, which were divided into four groups depending on the PSA nadir level: less or equal 0.2 ng / ml (1 group), 0.21-0.5 ng / ml (group 2), 0.51-1 ng / ml (group 3) and> 1 ng / ml (group 4). sensitivity, specificity, predictive value, and 5-year biochemical relapse-free survival according to the Stuttgart definition and the Phoenix definition in the PSA nadir groups. RESULTS: The median (range) of the observation period for the patients was 5.3 (3-7) years, the mean time to reaching PSA nadir was 14.5+/-2.6 weeks. PSA nadirs less or equal 0.2, 0.21-0.5, 0.51-1.0 and > 1 ng/ml were achieved in 231 (35.1%), 132 (20.0%), 105 (15, 9%) and 190 (28.8%) patients, respectively. Survival without biochemical relapse in accordance with the Stuttgart definition in the four groups allocated for the PSA nadir was 82, 65, 43 and 32%, respectively (p<0.001), according to the Phoenix definition - 94, 74, 66 and 47% (p<0.001) respectively. According to the results of the control biopsy, 601 (91.3%) patients in the 1st and 2nd groups had a negative oncological status (approximately 85%). CONCLUSION: This study confirms that PSA nadir after HIFU ablation predicts biochemical recurrence-free survival and is a reliable marker that is easy to integrate into routine clinical practice.

[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.

[Cytoflavin in the treatment of patients with chronic abacterial prostatitis and erectile dysfunction].

The problem of chronic prostatitis (CP) and erectile dysfunction (ED) involves not only their high prevalence, but also the insufficient effectiveness of their treatments. In this regard, there is need for administration the pathogenetic drugs with antihypoxic, antioxidant and neuroprotective effects and improving blood flow to the genitals. The study included 60 men with CP associated with ED, aged 22 to 60 years. Patients were randomized into 2 groups of 30 people. Patients of comparison group received baseline therapy (alpha1-adrenoblockers, non-specific anti-inflammatory drugs, digital prostate massage and vacuum phallostimulation). Antibiotics were applied on the basis of their potential effectiveness in chronic abacterial prostatitis. In addition to the above treatment, patients of main group received step-down therapy with cytoflavin (in infusion, then oral administration). Positive dynamics was noted in both groups of patients; however, according to the indicators of the severity of pain and dysuria, as well as quality of life, positive dynamics in the main group of patients was more significant. Similarly, the dynamics of objective criteria for inflammation in the prostate gland was more pronounced when using cytoflavin. After treatment, the rigid phase of erection during vacuum fallotest occurred within 2-3 min from the beginning of the procedure in 16 (53.3%) patients of main group and only in 9 (30%) patients of comparison group. During follow-up examination at 6 months after treatment, stable remission was found in 75% of patients of main group. Thus, the inclusion of cytoflavin in the scheme of complex treatment of patients with abacterial CP associated with ED is pathogenetically justified, makes it more efficient and provides good DFS.

[Combined physiotherapy of chronic infectious prostatitis].

Our experience with therapy of 259 outpatients with chronic infectious prostatitis (CIP) aged 16-55 years has demonstrated that combined treatment of CIP with rectal digital massage of the prostate, electrophoresis of chimotripsin solution with dimexide and local magnetotherapy (Intramag unit) significantly raises treatment efficacy, shortens treatment, prevents complications.

[Comparative assessment of the diagnostic value of the laboratory diagnostic methods for trichomoniasis].

The authors compared the sensitivity and specificity of currently available methods for laboratory diagnosis of trichomoniasis, by examining 971 persons. The highest frequency of T. vaginalis was detected by studies of a stained smear (37.4%), culture tests (19.0%); polymerase chain reaction (PCR) (17.1%), immunofluorescence tests (12.7%), wet smear test (2.7%). Enzyme immunoassay yielded positive results in 36.2% of cases. The use of PCR and culture tests frequently provided similar results (92.0%). The authors have proposed an algorithm of a laboratory study including wet smear microscopy, PCR, and culture tests as basic methods. They have noted the higher detection rates of T. vaginalis when analyzing during draining physiotherapeutic procedures (endocervical vibratory massage with vacuum aspiration in females and pneumovibratory massage of the prostate with endourethral chemotrypsin electrophoresis in males).

[Laboratory diagnostics of urogenital clamidiosis].

Laboratory diagnostic tools of urogenital clamidiosis--PCR, ELISA (IgG and IgM) and direct immunofluorescence (DIF)--were comparatively analyzed. The positive PCR result was checked by another PCR test with a different primer; 5 false positive responses were registered (specificity 99.6%). As against PCR, the sensitivity of ELISA made 53%, its specificity -75.5%, the diagnostic value of positive result -58%, the diagnostic value of negative result -71.6% and the diagnostics accuracy -66.7%. The respective DIF parameters were as follows: 36%, 90%, 81.5%, 54.2% and 60.9%. A high rate of detection (above 90%) of the conditionally pathogenic microflora associated with Chlamydia trachomatis (above 110 microbe cells/ml) was pointed out. Hardnerelli and ureaplasms were more often found in female smears, staphylococci and enterococci--in male sperm. It is underlined as important to hold complex examinations for Chlamidia (PCR, ELISA and DIC as an additional test) combined with bacteriological quantification of the conditionally pathogenic microflora and determination of its resistance to antibiotics.

[Paraendocervical route for metronidazole administration in complex treatment of chronic Trichomonas endocervicitis]. / Primenenie paraéndotservikal'nogo sposoba vvedeniia metronidazola v kompleksnom lechenii khronicheskogo trikhomonadnogo éndotservitsita.

The data on paraendocervical administration of metronidazole in the treatment of patients with relapsing Trichomonas endocervicitis are presented. Metronidazole was administered as 0.5% solution in a dose of 0.04 g once a day for 8-10 days in complex traditional therapy including oral use of metronidazole and immunocorrigating and local treatment. It was shown that paraendocervical administration of the protistocidal agent provided earlier regression of the urogenital symptoms and 2.8 times lower frequency of the relapses.
