Introduction. The choice of method of urine derivation is main question after removal of the urinary bladder. Materials and methods. The choice of the method of urine derivation is based on the indications and contraindications to a particular method, the patient's wishes, his somatic status and individual anatomical features, as well as kidney function. Bricker procedure is the most used form of incontinent urine derivation. 10% of patients after the formation of Bricker ileumconduitis have complications from anastomoses, most often-left ileo-ureteral anastomosis. Li Y. et al. modified the standard procedure for the formation of ileal conduit in order to minimize complications associated with left ileo-ureteral anastomosis. Description of a clinical case. The article presents a clinical case of using Li-Kotb modification technique of ileal conduit. Discussion. Due to the presence of a single functioning left kidney in the patient, we sought to provide reliable urine derivation. Therefore, we leaned towards a modified method of forming of ileal conduit using Li-Kotb method, rather than the classical technique. Conclusion. According to the authors of the method, the modified Bricker ileal conduit formation technique is safe, reproducible and reduces the risk of failure and stricture of the left ileo-ureteral anastomosis.

Xanthogranuomatous pyelonephritis (CP) is an aggressive form of interstitial nephritis, including purulentdestructive and proliferative processes in the kidney to form granulomatous tissue. The difficulty of diagnosis of CP, low illumination of this problem in the literature are the reason for the publication of even a single observation. The exact diagnosis of the disease can be established only with morphological examination and, as a rule, after surgical treatment. The clinical observation of the treatment of the child 15 years xanthogranulomatous pyelonephritis, inpatient Nizhny Novgorod regional children's teaching hospital. A boy M. at the age of 15 years entered the clinic of acute pyelonephritis (fever up to 38–39°С, abdominal pain and left side). From anamnesis it is known that at the age of one year the child was diagnosed with recurrent leukocyturia. Urological examination revealed hydronephrosis of the lower half of the double kidney on the left. At the age of 7 he was operated on (due to negative dynamics), reconstructive surgery was performed – prilohanochnaya pyeloplasty on the lower segment of the double kidney on the left. In the subsequent exacerbations of pyelonephritis was not. 6 years after hepatitis and kidney injury (contusion), there was a significant increase in dilation of the abdominal system of the lower segment of the left kidney with exacerbation of secondary pyelonephritis. According to intravenous urography, MSCT, MRI (performed to exclude Wilms tumor), the absence of the function of the lower segment of the kidney with a sharp increase in its size was determined. After the preoperative examination, the left kidney was examined, in which the signs of xanthogranulomatous pyelonephritis (renal tissue of bright yellow color), lower left heminephroureterectomy were found, the Diagnosis was confirmed by morphological examination. In the postoperative period, a cyst of the lower pole of the kidney was formed, cured by percutaneous drainage, sclerosing under ultrasound control, followed by recovery. Thus, this clinical case demonstrates the complexity of the diagnosis of CP, which often occurs under the mask of a variety of diseases, including acute pyelonephritis and kidney tumors. Reliable diagnosis of xanthogranulomatous pyelonephritis is possible only with the help of histological examination of pathological tissues.

Для полимерных композиционных материалов (ПКМ) с армирующим наполнителем из натуральных волокон одними из проблем являются оценка качества подготовки волокон и определение динамики взаимодействия волокон и полимерной матрицы. Актуальность проблем обусловлена расширяющимся объёмом исследований ПКМ с растительными волокнами и разнообразными видами и глубиной предварительной обработки растительных волокон. Предметом исследования выступил стандартный метод определения смачиваемости целлюлозных материалов. Цель экспериментального исследования – предложить модифицированный метод определения смачиваемости, потенциально пригодный для оценки качества подготовки армирующих наполнителей ПКМ из растительных волокон. Использован стандартный по ГОСТ и модифицированный метод определения смачиваемости. В качестве пробного материала использовали целлюлозу древесную, полубелёную сульфитную из хвойной древесины в форме целлюлозной папки. Образцы целлюлозы механически разрыхляли до элементарных волокон и испытывали на смачиваемость. Использовали три схемы испытаний – взвешивание стаканчика с навеской, погруженного в воду (схема 1), взвешивание сосуда с водой (схема 2), стандартную методику по ГОСТ (схема 3). По схемам 1 и 2 измерения проводили в течение до 120 секунд, по схеме 3 – 30 секунд. Эксперименты проводили в трёхкратной повторности. Сущность модифицированного метода определения смачиваемости основана на постоянном контроле массы навески по мере сорбции водной влаги. Полученные закономерности кинетики процесса показали, что количество водной влаги, впитываемой образцами, нелинейно меняется во времени. Величины смачиваемости, определённых по различным схемам, с учётом отклонений, соответствуют друг другу. Определение смачиваемости по модифицированному методу предложено проводить в течение 120 секунд, периодически контролируя показания весов. Предложенный модифицированный метод может быть использован в исследовательских целях для изучения динамики впитывания воды и сравнения поведения различных целлюлозных материалов для ПКМ с матрице на основе гидрофильных полимеров. For polymer composite materials (PCM) with a reinforcing filler made of natural fibers, one of the problems is to assess the quality of fiber preparation and determine the dynamics of the interaction of fibers and a poly-dimensional matrix. The urgency of the problems is due to the expanding volume of research on PCM with plant fibers and various types and depth of pretreatment of plant fibers. The subject of the study was a standard method for determining the wettability of cellulose materials. The purpose of the experimental study is to propose a modified method for determining wettability, potentially suitable for assessing the quality of preparation of reinforcing fillers of PCM from plant fibers. The standard GOST and modified method for determining wettability were used. As a test material, wood cellulose, semi-green sulfite from coniferous wood in the form of a cellulose folder was used. Cellulose samples were mechanically loosened to elementary fibers and tested for wettability. Three test schemes were used – weighing a cup with a suspension immersed in water (scheme 1), weighing a vessel with water (scheme 2), standard procedure according to GOST (scheme 3). According to schemes 1 and 2, measurements were carried out for up to 120 seconds, according to scheme 3 – 30 seconds. The experiments were carried out in threefold repetition. The essence of the modified method for determining the permeability is based on the constant control of the weight of the suspension as the sorption of water moisture. The obtained laws of the kinetics of the process showed that the amount of water moisture absorbed by the samples varies non-linearly over time. The wettability values determined according to various schemes, taking into account deviations, correspond to each other. The determination of wettability by the modified method is proposed to be carried out within 120 seconds, periodically monitoring the readings of the scales. The proposed modified method can be used for research purposes to study the dynamics of water absorption and compare the behavior of various cellulose materials for PCM with a matrix based on hydrophilic polymers.

COMPARISON OF MODIFIED METHOD OF LIGATION OF INTERSPHINCTERIC FISTULA TRACT (LIFT) AND STANDARD OPERATIONS IN PATIENTS WITH TRANSSPHINCTERIC RECTAL FISTULAS Kryvoruchko I.A. , Firsyk T.M.,.  Bozhko O. P. Background. The search for and development of new minimally invasive methods for the surgical treatment of anal fistulas is a relevant area of surgery. Such methods combine less traumatization and preservation of the sphincter’s complex. Employment of such methods for surgical treatment of anal fistulas reduced the time of stay of patients in the hospital and improved their quality of life. Subjects and methods. A retro- and prospective study involved 58 patients with uncomplicated transsphincteric anal fistulas. All patients were treated in the hospital from January 2014 to April 2019.  The patients were divided into two groups: the first group included 32 patients who were operated on according to the standard procedure using fistulotomy and Seton procedure; the second group consisted of 26 patients who were operated on using the modified LIFT method. Results. Most of these patients (72.4%) were men at the age of 42.536.79. The median of BMI was 25.7 kg/m2. There wasn’t mortality after operations. The median follow-up was 21 (6-48) weeks. In the first group there were 3 cases (9.3%) of anal sphincter insufficiency and 7 cases of recurrent fistulas (21.9%) at different times after surgery.  In the second group there were no anal sphincter failure following administration of the modified method LIFT, but there were 15.4% of recurrent anal fistulas. Conclusion. The proposed modified method of ligation of intersphincteric fistula tract is an effective method for the treatment of anal fistulas. The results obtained suggest that the developed method can be used to treat other types of anal fistulas.  Keywords: transsphincteric anal fistula, surgical treatment, LIFT technique, postoperative complications.   Резюме.

A method of determining the lignin content of fresh plant tissue without preliminary drying has been devised. Prior to the final lignin determination with 72% sulphuric acid, the tissue is cut up, extracted with ether saturated water in a Waring Blendor, refluxed with 1% hydrochloric acid, and finally extracted with ethanol–benzene. For comparison, determinations were carried out by the above method and the standard A.O.A.C. procedure on material that had been air-dried at room temperature. Both greenhouse and field grown oat plants cut at various growth stages were used in this study. The modified method gave lower lignin values than the standard procedure with young succulent tissue. This difference decreased as the age of the tissue increased, and the results by all methods were very similar with oat straw. That the modified procedure on fresh tissue removes more interfering nitrogenous material than the other methods used is indicated by the lower nitrogen content of the lignin isolated. The absolute methoxyl contents of the residues isolated from dried tissue were greater than of those isolated from fresh material (from the same source). This may have been due to the inclusion of more methoxyl-containing carbohydrates in the former residues.

The article presents a clinical case of a 25-year-old patient with progressive diffuse B-cell lymphoma with lesions of the S2 nerve root, accompanied by pain syndrome that is not relieved by systemic multimodal analgesia using opioids, antiepileptic and non-steroidal anti-inflammatory drugs. Polyneuropathy, secondary immunodeficiency, thrombocytopenia grade IV refractory to platelet concentrate transfusion, Guillain-Barre syndrome, impaired the somatic status and intensified the pain syndrome. Local anesthetics epidural port was successfully implanted to improve quality of analgesia. As a result of prolonged epidural infusion of 0.2% ropivacaine with titration rate from 4 to 7 ml/hour depending on the severity of the pain syndrome, that significantly improved patients quality of life was achieved by reducing the intensity of pain and increasing duration of night sleep. In the early postoperative and long-term follow-up periods (14 days), there were no hemorrhagic and infectious complications associated with the use of the epidural port.

Introduction: There are multiple causes of end-stage renal disease (ESRD). One of the most uncommon cause is the obstruction of the lower urinary tract due to the development of new endourological procedures and the improvement in clean intermittent catheterization. However, urodynamic problems that require solutions to bladder problems continue to appear that will directly affect the function of the kidney graft. Objective: Clearly state the possibility of performing a bladder conduit technique at the same time as a kidney transplant as an option for patients who undergo kidney transplantation with incompetent bladders. A clinical case is described as an example. Material and Methods: The clinical case of a patient with left cutaneous ureterostomy due to neurogenic bladder who is a candidate for renal transplant is presented. An ileal conduit type urinary diversion is performed in the same surgical act as the renal transplant. The existing literature is analyzed in relation to the different types of urinary diversion and how they affect renal function. Clinical Case and Results: Here we present a 50-year-old male with hypotonic bladder since 19th years old secondary to sacral lipectomy. He developed a progressive deterioration of renal function until he started hemodialysis program in 2018. Ileal conduit and renal transplant are performed through right pararectal incision, reimplantation of the ureter in the antimesenteric side of the intestinal loop. No increase of complications was observed in the post-transplant. The patient was discharged the 7th day after surgery. Serum creatinine at 6 months after renal transplantation 1.2mg/dl. Conclusion: Ileal conduit is a valid resource in patients with neurogenic bladders or with emptying problems whose solution puts at risk the functionality of the graft. Similar recovery is observed in time compared to a kidney transplant without ileal shunt. Post-transplant graft function was good without an increase in complications.

AbstractThe effectiveness of some modifications of the Caldwell-Luc standard procedure in the prevention of postoperative mid-facial sensitivity disorders was investigated in a prospective comparative study at the ENT Department, Faculty of Medicine, University of Athens, Greece, from 1986–1992. Sixty-nine maxillary sinuses were operated on in 61 patients suffering from benign pathological conditions. The modifications concerned the type of mucoperiosteal incision and the site and size of the created anterior antrostomy. Only 8.7 per cent of the sinuses operated on by the modified technique presented with post-operative disorders whereas among those operated on by the classical technique, the ratio climbed to 33 per cent. In view of the findings of this study, the modifications applied can be valuable in treating non-extensive maxillary sinus disease with minimal post-operative sensitivity disorders.
