Summary:

Purpose: to establish the nature of changes in markers of angiogenesis and inflammation in the blood serum and urine in patients with obstruction of the ureteropelvic segment or upper third of the ureter by ureteral stones in different terms of the kidney drainage. Material and Methods. 53 patients with urolithiasis have been examined. The main group consisted of 33 patients with concrements of the upper third of the ureter or renal pelvis-ureteral segment with pres- ent obstructive uropathy. The comparison group consisted of 20 patients with calculi of the kidney without symptoms of obstruction. In the main group patients underwent drainage of the kidney by percutaneous-nephrostomy puncture. Results. Patients of the main group revealed a significant increase in the levels of markers of angiogenesis and inflammation before the kidney drainage. The level of MCP-1 correlated with the level of serum creatinine. In the process of drainage the levels of these markers were decreased as a result of increased GFR. Determination of the concentration of urinary VEGF, IL-8 and MCP-1 in patients may have clinical value in personalized management of patients with obstructive uropathy to determine the optimal terms of the second stage of the surgical intervention. Conclusion. Determination of markers of inflammation and angiogenesis in the urine of patients in conjunction with assessment of renal function by creatinine level is important for determining the term of kidney drainage.

Year: 2017, volume 13 Issue: №2 Pages: 280-283
Heading: Urology Article type: Original article
Authors: Osnovin O.V., Popkov V.M., Fomkina O.A.
Organization: Saratov State Medical University
Summary:

Aim: to analyze the correlation between the unfavorable factors at newborn patients and children and the peculiarities of the course of urolithiasis in adults. Material and Methods. The data were received from questioning of 286 patients and their relatives, analysis of case histories and past medical histories. The material was statistically worked out. Results. The early development of urolithiasis (at patients under 30) was associated with the threat of termination of pregnancy, prematurity, excretory and digestive disorders at childhood in case of severe anamnesis of urolithiasis, and also malnutrition. Bilateral lesions of the urinary system were determined to be associated with artificial feeding and prematurity, digestive diseases and complicated anamnesis of urolithiasis, malnutrition, deprived living conditions and low income. Stones in calyces occurred at patients with different complications at birth. More frequent cases of stone formation in renal pelvis were observed at premature and malnutrition patients and patients with cardiovascular diseases occurred during the childhood. Stones in ureters were considered as a result of respiratory diseases effect. Conclusion. Unfavorable factors occurred at birth and childhood, factors concerned with deprived social conditions and psychological problems influence the onset and the course of urolithiasis.

Heading: Urology Article type: Original article
Authors: Chekhonatskaya M.L., Rossolovsky A.N., Bobylev D.A.
Organization: Saratov State Medical University
Summary:

The aim of the article: evaluation of the results of treatment of patients with nephrolithiasis by distance shock-wave lithotripsy on the basis of the data on kidneys received from multispiral computed tomography. Material and Methods. The study involved 46 patients who were hospitalized in the clinic of urology with diagnosed urolithiasis with the pres- ence of a renal calculus from 10 to 17 mm in size. A complex of laboratory analyses including multispiral computed tomography was used. The concrement elimination was carried out by distance shock-wave lithotripsy Results. Correlation analysis and ROC-analysis did not show the efficacy of distance shock-wave lithotripsy comparing scanning procedures and distance shock-wave lithotripsy. Conclusion. The size and average density of a concrement according to multispiral computed tomography should not be served as a basis for prognosis of effective fragmentation of concre-ments by distance shock-wave lithotripsy in patients with urolithiasis caused by stones of 10-17 mm in size.

Year: 2009, volume 5 Issue: №4 Pages: 612-615
Heading: Urology Article type: Original article
Authors: P.I. Shuster, P.V. Glybochko
Organization: Saratov State Medical University, Omsk State Medical Academy
Summary:

Research objective is to study processes of lithogenesis at patients with considerably cured urolithiasis at androg-enous therapy. The patients observed in urological clinic of Omsk State Medical Academy have been included. By means of method «case-control» 2 groups have been formed : the basic group - 10 patients with considerably cured urolithiasis and with hypogonadism receiving androgenous therapy and the comparison group - 10 patients with considerably cured urolithiasis and with hypogonadism without receiving androgenous therapy. Processes of lithogenesis at patients who received androgenous therapy have proceeded statistically significantly in comparison with patients without receiving androgenous therapy. It has been proved that there is a negative influence of testosterone deficiency on processes of lithogenesis. The obtained data demonstrate that lithogenic processes at patients with hypogonadism are more expressed and lead to more frequent urolithiasis recurrence. Noninvasiveness, technical simplicity and availability of method «Litos-test» provides its use for express-screening method for inspection of the population and for estimation of antireccurent efficiency of androgen replacement therapy at men with urolithiasis

Heading: Urology Article type: Original article
Authors: P.V. Glybochko, P.I. Shuster
Organization: Saratov State Medical University, Omsk State Medical Academy
Summary:

Study of age-specific hypogonadism correlation through osteopenia with urolithiasis at men is a new perspective direction uniting endocrinology and somatic urology. Besides comparison groups patients observed in the urological clinic of Omsk State Medical Academy have been included in one-stage continuous research. The method of stratification has allowed distinguishing two groups: group of men with urolithiasis - 140 patients and comparison group - 30 men without urolithiasis. Research methods have included questioning of patients by means of questionnaire AMS and international erectile function index, estimation of body weight index, biochemical indicators of blood serum, general testosterone, ionized calcium, densitometry. Occurrence of hypogonadism at men with urolithiasis has accounted 57,1 % (80 patients), in comparison group (men without urolithiasis) it has accounted 23,3 % (7 patients). Occurrence of decrease in mineral density of bone tissue has been statistically and significantly higher at patients with hypogonadism that proves interrelation of osteo-calcium metabolism disturbances and urolithiasis development. The 1st group has accounted 8,7 % of patients with osteoporosis, the 2nd group - 3,3 %. The 1st group has accounted 70,0% of patients with osteopenia, the 2nd group - 25,0%. Level of testosterone is associated with degree of expressiveness of decrease in mineral density of bone tissue. The lowest indices of testosterone have been at men with osteoporosis. Revealed correlations have shown adverse influence of hypogonadism not only on the sexual status of patient, but also on condition of osteo-calcium metabolism, disturbances of which may cause urolithiasis

Authors: P.V. Glybochko, A.N. Rossolovskiy, A.N. Ponukalin, N.B. Zakharova, G.N. Maslyakova, A.M. Napsheva
Organization: Saratov State Medical University
Summary:

The aim of present work has been an assessment of degree of tubulointerstitial modifications of kidney parenchyma in patients with urolithiasis in different stages of surgical treatment using non-invasive mediators of nephrofibrosis and angiogenesis. The results of operations of 65 patients have been analysed. The content of nephrofibrosis molecular mediators in blood serum and urine has been determined. It has been shown that the most informative non-invasive mediators of tubulointerstitial fibrosis are IL12, VEGF in blood serum and b2-microglobulins MG, MCP 1 and NO excreted with urine. Patients with bilateral urolithiasis accompanied by expressive tubulointerstitial damages have had high indices of nephrofibrosis in postoperative period that can indicate irreversibility of these changes, leading to progression of chronic kidney disease

Efficiency and safety of androgenic therapies of hypogonadism at patients with considerably eliminated urolithiasis

Year: 2009, volume 5 Issue: №3 Pages: 327-332
Heading: Urology Article type: Original article
Authors: P.I. Shuster
Organization: Omsk State Medical Academy
Summary:

The weakest unit in treatment of urolithiasis is revealing in each specific case etiological factor of lithogenic and carrying out etiotropic therapy, and, hence prevention of urolithiasis relapse. The study of correlation of hypogonadism through osteosinging with urolithiasis at men is the new perspective direction uniting Endocrinology and somatic Urology.
In prospective cohort research the patients divided into 2 groups have been included: basic group - patients with considerably cured urolithiasis and hypogonadism, received androgenic therapy (30 persons); comparison group -patients with considerably cured urolithiasis and hypogonadism, not receiving androgen therapy (30 persons).
Used: questioning on questionnaire AMS, the International index of erectile functions (IIEF-5), index of weight of a body, haemoglobin, hematocrit, biochemical indicators of blood serum, densitometry, general testosterone, PSA, and ionized calcium.
After contra-indications exception (cancer of prostate gland, expressed increase of haemoglobin and hematocrit) the basic group patients were prescribed one of testosterone group drug during the period not less than 6 months: Androgel (Solvay Pharma), Nebido (Bayer Schering Pharma), Sustanon-250 (Organon), Omnadren-250 (Polfa).
At the moment of the therapy beginning, patients of both groups were comparable in all investigated indices.
Relapse of urolithiasis: against androgenic therapy - 28,6%, in comparison group - 63,2%. The obtained data testify to efficiency of androgenic therapy in respect to prevention of urolithiasis at patients with hypogonadism and confirm the role of hypogonadism as one of etiopathogenetic development factors of urolithiasis.
Androgenic therapy was safe. All patients had insignificant increase of general PSA level and statistically significant increase of haemoglobin and hematocrit indicators. However, the received changes did not demand cancellation, or therapy correction.
