[Inluence of osteoporosis and its causative factors on the prevention of recurrence of urinary stone disease].

INTRODUCTION: The aim of postoperative examination, treatment and follow-up of patients with urinary stone disease is a prevention of recurrence. A choice of method of prevention is based on the results of postoperative examination with consideration of etiological factors of urinary stone disease. An analysis of influence of osteoporosis and its causative factors on the recurrence of urinary stone disease is presented in the article. AIM: to clarify the influence of osteoporosis and its causative factors on excretion of calcium, uric acid and recurrence of urinary stone disease. MATERIALS AND METHODS: A total of 86 patients after surgical treatment of urinary stone disease were included in the study. A physicochemical analysis of stones and their fragments, excretion of calcium and uric acid were done postoperatively. The risk factors for osteoporosis were identified using specific questionnaire. Bone mineral density (BMD) was assessed by X-ray densitometry. After X-ray phasic analysis of the stones and studying of the daily excretion of calcium and uric acid, 10 and 7 patients were prescribed to thiazide diuretics and allopurinol, respectively. In 69 patients (80.2%) there were no indications to the treatment and all of them were included in control surveillance group. RESULTS: Calcium oxalate stones were predominated in patients who were under surveillance (=0,0254). A prevalence of risk factors for osteoporosis was similar in all groups (=0,2156), as well as rate of decrease in BMD (=0,64). In patients taking thiazide diuretics, a significant decrease in daily calcium excretion was found (=0,0054) without significant changes in excretion of uric acid and diuresis volume. Among patients receiving allopurinol there was a significant decrease in daily uric acid excretion (=0,021), without significant changes in excretion of calcium and diuresis volume. There were no significant changes of these values in the control group. A recurrence of urinary stone disease in treatment group was detected in 4 patients with a decrease of BMD after 381+/-61 days, while in control group there were 5 recurrences in patients with decreased BMD and I recurrence in patient with normal BMD after 836+/-64 days. CONCLUSION: Treatment aimed at prevention of recurrence of urinary stone disease allows to correct detected metabolic disturbances. However, such factor as the decrease in BMD can influence on the rate and frequency of recurrence of urinary stone disease. A clarifying of risk factors for osteoporosis and diagnosis of osteoporosis allow to give reliable recommendations for its treatment and to decrease risk of recurrence of urinary stone disease.

[Psyhosomatic aspects of dysuria in women from the perspective of an interdisciplinary approach].

In clinical practice, urologist often has to treat women who have various forms of dysuria that do not have a pathomorphological substrate and manifest by various types of urinary disturbances and pathological sensations in the urinary tract. The relevance of this topic can be explained by the increasing prevalence of dysuria, its recurrent nature and insufficient efficiency of routine urotherapy, including the use of an extensive armamentarium of drugs and interventions, as well as by pronounced discomfort and a significant decrease in the quality of life and working capacity in the socially active adult patients. Despite a steady growing of interest in this problem, most researchers use a variety of questionnaires and evaluation methods and receive extremely unreliable data that do not contribute to an understanding of the serious psychourological problem of a particular patient with dysuria. In this article, such cases are discussed from the perspective of an interdisciplinary approach using the qualification apparatus of modern psychosomatic medicine and relying on the clinical experience of leading specialists in the field of urology and psychosomatics. The introduction of a comprehensive multidisciplinary approach into clinical practice will contribute to adequate referring, timely provision of specialized care, a reduction of medical costs and an increase in the quality of life in a large group of patients with dysuria.

[Clinical value of Canephron N after surgical treatment of urinary stone disease].

BACKGROUND: The drug Canephron N is a combination of extracts of centaury, lovage and rosemary. Moderate antispasmoic, anti-inflammatory, antioxidant, diuretic and antimicrobial effects are of great interest for urological practice. The optimal combination of components that were made of herbal medicine allows to use their synergistic effect for prevention of recurrence of urinary stone disease. The experience of using the drug Canephron in clinical practice is of great interest. AIM: to clarify the clinical efficiency of Canephron N in patients with urinary stone disease after surgical treatment and to evaluate the changes in diuresis and calcium excretion. MATERIALS AND METHODS: The results of using the drug Canephron after surgical treatment of urinary stone disease are provided. The changes in diuresis and calcium excretion in 75 patients undergone surgical treatment of urinary stone disease were studied. Patients after ureteroscopy, percutaneous nephrolithotomy and extracorporeal shock-wave lithotripsy were prescribed treatment to prevent stone formation including herbal drug Canephron N. RESULTS: At baseline, there was negative correlation between 24-hours diuresis and calcium excretion in all groups. During follow-up, a positive correlation between 24-hours diuresis and calcium excretion was found in patients receiving Canephron N and other types of treatment. The average follow-up was 390 days. During this period, recurrence was noted in 1 patient receiving Canephron, 4 patients in patients who took other drugs and in 5 patients who didnt receive any treatment. CONCLUSION: Risk factors of stone formation persist after surgical treatment of urinary stone disease. This is reflected in a negative correlation between 24-hour diuresis and calcium excretion. During treatment, a positive correlation between diuresis and calcium excretion was noted in patients with urinary stone disease. The use of drugs that affect stone formation as well as herbal medicine Canephron N allow to obtain comparable ratio of diuresis and calcium excretion.

[Characteristic features of urinary calcium excretion and osteoporosis risk factors in patients with urolithiasis].

RELEVANCE: The prevalence of urolithiasis and osteoporosis (OP) indicates that these diseases may be found concurrently in the same patient. The detection of risk factors for OP and disorders of calcium metabolism in patients with urolithiasis is of interest in the context of primary stone formation and metaphylaxis. AIM: To identify risk factors for osteoporosis and disorders of calcium metabolism in patients with urolithiasis. MATERIALS AND METHODS: Osteoporosis risk factors were studied in 45 urolithiasis patients undergoing surgical treatment. Patients were asked to fill out the osteoporosis risk factor questionnaire, and urinary calcium excretion was measured in 24-h collections. RESULTS: Risk factors for osteoporosis were detected in 20 (44.4%) urolithiasis patients. Patients with osteoporosis risk factors identified by the questionnaire were statistically significantly older (p=0.032). Osteoporosis risk factors were found in 20% of patients with newly diagnosed urolithiasis and 24.4% of patients with recurrent urolithiasis. The study patients showed increased urinary calcium excretion and decreased diuresis. The negative correlation between urinary calcium excretion and 24-h diuresis was greater in patients who had than in those who did not have osteoporosis. CONCLUSION: An increase in urinary calcium excretion and a decrease in diuresis can be a predisposing factor for the recurrence of urolithiasis. In patients with risk factors for osteoporosis, it can provide a rationale for administering drugs aimed at preventing stone formation (thiazide diuretics).

[Dosage forms of sildenafil in the management of erectile dysfunction].

The experience in the management of erectile dysfunction shows that taking even the most effective medications in tablet form may be inconvenient due to the need for natural settings for intimacy. The phosphodiesterase type 5 inhibitor sildenafil, presented in the orally disintegrating film formulation (Dynamic Forward), differs from all forms of the drug for the treatment of erectile dysfunction available in the Russian pharmaceutical market. The drug in the form of a film makes it possible to realize a pathogenetic approach to treating ED without changing the patients habitual way of life.
