A New Approach for Split Renal Function Assessment Based on 3D-Models Generated from Contrast-enhanced Multi-slice Computed Tomography (Msct) Scans and Mathematical Analysis: A Pilot Study

Introduction: Instrumental methods of examination may alter the course of treatment and patients’ management: from minimally invasive nephron-sparing procedures to radical operations. Objective:to present preliminary data on split kidney function assessment (in a kidney volume, e.g. segment) in patients with urological diseases.Materials and methods: A prospective study was launched in aResearch Institute for Uronephrology and Reproductive Health from November, 2015 to February, 2017. 31 patients were enrolled into the study: 15 with stone kidney disease, 2 with kidney anomalies, 14 with renal tumors. Contrast-enhanced CT with 3D-models andmathematical analysis were performed in all patients. Correlation between CT-based and renal scintigraphy-based measures of split renal function was estimated. Results: CT-based methods for the calculation of split renal function with 3D-models showed correlation with renal scintigraphy (p<0.004, ttest). Conclusion: A new approach for split kidney function assessment based on contrast-enhanced CT with 3D-models and mathematical analysis allows for both acquiring detailed data on clinical anatomy and evaluation of renal function to promote preoperative decision-making

ТРЕНИРОВКА МЫШЦ ТАЗОВОГО ДНА В ЛЕЧЕНИИ НЕДЕРЖАНИЯ МОЧИ ПОСЛЕ РАДИКАЛЬНОЙ ПРОСТАТЭКТОМИИ

The incidence of urinary incontinence after radical prostatectomy is 0.8 to 87%. This category of patients has pelvic floor muscle weakness and reduced perineal reflex. The treatment of these patients uses a pelvic floor exercise system that is to enhance muscle tone and to develop strong reflex contraction in response to a sudden rise in intraabdominal pressure. Pelvic floor muscle training belongs to first-line therapy for urinary incontinence occurring within 6 to 12 months after prostatectomy. The ability to control pelvic floor muscle knowingly and to train them allows one not only to increase the closing capability of sphincter mechanisms, but also to suppress involuntary detrusor contractions. We used this method in 9 patients who had undergone radical prostatectomy. The duration of pelvic floor muscle training under control was up to 25 weeks. During this period, the symptoms of incontinence were relieved. No contraindications or adverse reactions have put this method in first-line therapy for post-prostatectomy urinary incontinence.The incidence of urinary incontinence after radical prostatectomy is 0.8 to 87%.

Training in exercises for pelvic floor muscles of patients with an urinary incontinence after radical prostatectomy

Training of muscles of a pelvic bottom under control of biofeedback is applied at 87 patients with an urinary incontinence after a radical prostatectomy. Biofeedback increases management and control of a pelvic floor. At good ability of management of muscles of a pelvic floor the median of restoration was 4 months. Without opportunity of management of muscles of pelvic floor restoration was 9.4 months.</em

THE CURRENT STATE OF ANTIBIOTIC RESISTANCE AND THE COMPOSITION OF PATHOGENS OF URINARY TRACT INFECTIONS IN PREGNANT WOMEN

Introduction. The main treatment component of asymptomatic bacteriuria, acute cystitis and pyelonephritis in pregnant women is antibiotic therapy, which in many patients is prescribed empirically. For successful selection of the drug, it is necessary to know both the structure of pathogens and the current profile of their antibiotic resistance.Purpose of research. The study of species composition and resistance to antibiotics of bacteria that cause urinary tract infections (UTIs) in pregnant women in the Moscow RegionMaterials and methods. The study included 104 pregnant women with uncomplicated UTIs who were observed and treated at the Lapino Clinical Hospital between 2016 and 2017. The material for bacteriological studies was the midstream portion of urine or urine collected by a catheter.Results. 90 patients had asymptomatic bacteriuria, 10 had acute cystitis, and 4 had acute gestational pyelonephritis. The structure of the pathogens of UTI is presented: E. coli, Enterococcus faecalis, Klebsiella pneumoniae, Proteus spp., Staphylococcus spp., Streptococcus spp., Enterobacter cloacae. The most frequently detected pathogens were E. coli (67.3%) and E. faecalis (50%). Resistance rate of E.coli strains more than 20% was detected to ampicillin (36.4%), amoxicillin / clavulanate (23.2%), trimethoprim / sulfamethoxazole (27.4%), nalidixic acid (20.7%), cephalosporins 2 and 3 generation (respectively, 25.7% and 24.3%). Resistance rate more than 20% in Enterobacteriaceae family strains was detected to trimethoprim/sulfamethoxazole (24.4%), nalidixic acid (20.7%), cephalosporins 2 generations (21.7%). Antibiotic resistance of E.coli and other Enterobacteriaceae family taxons less than 10% was noted only with respect to carbapenems (0%) and fosfomycin (1.5% and 3.5%, respectively).Conclusions. It is expedient to use the obtained data on the composition and sensitivity profile of uropathogens in UTIs in pregnant women when choosing starting empirical antibiotic therapy. Disclosure: The study did not have sponsorship.

Effectiveness and safety of Tadalafil-SZ (NJSC “Northern Star”) at 5 mg / day in patients with symptoms of voiding dysfunction due to prostatic hyperplasia

The study objective is to evaluate effectiveness and safety of Tadalafil-SZ (NJSC “Northern Star”) at 5 mg / day in treatment of patients with symptoms of voiding dysfunction due to prostatic hyperplasia.Materials and methods. The study was conducted at the “Family Polyclinic No. 4” between January and June of 2019 and included 74 patients. Effectiveness was evaluated using the International Prostatic Symptom Score, International Index of Erectile Function, maximum urine flow rate and transrectal ultrasound examination.Results. After 3 months of therapy with tadalafil, positive dynamics of all characteristics were observed. Symptom severity prior to treatment was 11.50 ± 0.27 points, after treatment it was 10.00 ± 0.31 points. Maximum urine flow rate prior to treatment was 10.80 ± 0.20 ml / s, after treatment it was 11.10 ± 0.19 ml / s. The International Index of Erectile Function increased from 16.60 ± 0.30 prior to treatment to 20.20 ± 0.24 after treatment. Prostate volume before treatment was 43.70 ± 0.87 cm3, after treatment it was 40.30 ± 0.72 cm3.Conclusion. Tadalafil at 5 mg / day significantly decreases symptoms of voiding dysfunction and prostate volume, improves erectile function

Minimally invasive combined surgical treatment of postcoital cystitis

Introduction. Urethral transposition remains the most popular operation for postcoital cystitis, however, traumatism and complications, especially such as pudendal neuropathies, dyspareunia and anorgasmia, make us continue to search for effective, but safer techniques.The study objective is to evaluate the efficacy and safety of the proposed treatment of postcoital cystitis, including removal of urethrogymenal adhesions and subsequent paraurethral filler implantation, in comparison with isolated hymenoplasty.Materials and methods. Since 2013, 75 patients with postcoital cystitis have been treated. Patients were divided into two groups: main group – hymenoplasty (removal of urethral adhesions) with paraurethral filler implantation (n = 45), control group – hymenoplasty (n = 30). The gel was injected paraurethrically, fan-shaped, in the volume of 1–2 ml, from a point on the 6-hour conditional dial, creating a gel cushion and thus raising the meautus and distal urethra. To assess the quality of treatment, profile questionnaires were used.Results. In the main group of patient, the quality of life improved in 35 (78 %); in 5 patients, due to the process of biodegradation of the gel during 1 year, the cystitis recidivated, which required the filler reimplantation. In 5 patients, the operation was not effective. In the control group the efficiency of isolated hymenoplasty was noted in 3 (10 %) patients, relapse of cystitis occurred in 27 (90 %) patients, which later required the implantation of a filler. No complications were observed.Conclusions. The suggested combined technique allows to improve the results of treatment of patients with postcoital cystitis. The operation does not carry the risk of damage to the sprigs of the genital nerve, can serve as an alternative to traditional urethral transposition. The main disadvantage is the natural biodegradation of the gel, which may create the need for its reintroduction
