RESUMO
INTRODUCTION: Urolithiasis is one of the most common urological diseases in adults. Increased life expectancy of the population in developed countries, make urolithiasis topical issue and requires close attention. Due to the high risk of recurrent stone formation causing repeated surgical interventions, the issue of effective urinary stone metaphylaxis is very important today. MATERIALS AND METHODS: To study the current state of the problem of urolithiasis metaphylaxis among Russian urologists, an anonymous questionnaire was applied. A 25-question questionnaire was sent to e-mail to more than 4,000 Russian urologists. A total of 1,238 specialists completed the questionnaire. The database compiled from the received responses was processed and presented with descriptive statistics in the form of tables and charts. RESULTS: According to the survey, more than half of the 831 (67.1%) specialists specialized in the treatment of urolithiasis. It was noted that 626 (86%) inpatient urologists and 205 (40%) outpatient urologists specialized in the treatment of urolithiasis. Only 521 (69.6%) urologists specializing in surgical treatment of urolithiasis give a patient a stone fragment to analyze its chemical composition. At the same time, half of the respondents reported that less than 10% of patients come to them for further metaphylaxis. One of the main reasons for not analyzing the chemical composition of the stone was the fact that 877 (70,84%) specialists indicated the inaccessibility of analysis under the state guarantee program, 503 (40,63%) specialists indicated the patients satisfaction with the results of minimally invasive surgical treatment and lack of sufficient motivation for further examinations. At the same time, less than 3% of specialists can perform stone analysis within the framework of the state guaranty program. 1180 (96,8%) respondents practiced the prophylaxis of recurrent calculi formation, but only 336 (28,47%) performed comprehensive metabolic examination of all patients followed by prescription of drug therapy and appropriate diet. CONCLUSIONS: Our survey revealed low involvement of urologists at the outpatient level in the process of conservative treatment and metaphylaxis of urolithiasis, low activity of urologists in performing complex metabolic study and comprehensive prevention of recurrent stone formation, low percentage of performing chemical composition analysis of stone and low activity of urologists in performing primary litholytic therapy of urate stones. Based on this analysis of the responses of most Russian urologists, it is possible to formulate recommendations to remove the obstacles to providing patients with urolithiasis with quality medical care in terms of conservative therapy and metaphylaxis of urolithiasis.

Encrusted cystitis (IC) is a rare chronic inflammatory disorder of the bladder characterized by mucosal inflammation with encrustations. This pathological process is directly related to the activity of urea-splitting bacteria in the urine. Bladder encrustations are deposits of ammonium and magnesium phosphate, as well as struvite, on the surface of the urothelium. However, the pathogenesis of this disease has not been thoroughly studied. Treatment of encrusted cystitis is aimed to complete eradication of the uropathogen, surgical removal of encrustations, and lowering urine pH. Early diagnosis is a key prerequisite for effective treatment.

Currently, various types of stents are widely used in urological practice. One of the indications is the presence of upper urinary tract strictures. The factors leading to the development of strictures can be endogenous and exogenous, iatrogenic and non-iatrogenic, benign and malignant. After open, laparoscopic and X-ray-endoscopic procedures a double-J stent is usually placed or, less often, nephrostomy tube. It should be noted that both methods have certain side effects and may affect the patient's quality of life. To reduce the stent-related symptoms and increase their tolerability, various modifications of ureteral stents have been developed. In this article, we analyze the publications devoted to the most commonly used segmental stents without renal and bladder coils, such as Memokath, Uventa, Allium, Memotherm and nitinol stents manufactured by MIT LLC.

Percutaneous nephrolithotomy (PCNL) is the gold standard treatment of large and staghorn kidney stones. Despite technological progress and improvement of PCNL technique, this procedure is associated with complications and in some cases remain a challenge for endourologists. According to the time, complications can be divided into intra- and postoperative. Intraoperative complications include bleeding, injury of the renal collecting system, visceral organs, pulmonary complications, thromboembolic disorders, extrarenal migration of the stone fragments and incorrect nephrostomy tube placement. Postoperative complications include infection and sepsis, bleeding, persistent urinary fistula, infundibular stenosis and death of the patient. The different recommendations that might be useful for the timely diagnosis of various complications in patients undergoing PCNL are provided in the review. Additionally, information on treatment algorithms is included.

To date, percutaneous nephrolithotomy (PNL) is the standard treatment modality for large-volume renal stones and staghorn stones in patients with urolithiasis. Despite low invasiveness, this method is not without complications. This review discusses the most common complications and suggests methods for their prevention and appropriate management. To unify the study of complications they were categorized based on the modified Clavien classification. According to the available data, about 80% of the PNL complications belong to grade I-II complications and does not require any additional treatment. The most serious complications include sepsis, bleeding, and injury to nearby organs.

AIM: To analyze the sub-segment of mHealth devoted to assessing of the risk of recurrent stone formation and metaphylaxis of stone formation. To design a smartphone application (app.) in Russian language for urolithiasis patients. MATERIALS AND METHODS: Three working groups of urologists from three St. Petersburg clinics searched for downloadable medical applications relevant to the above requirements. After searching and analyzing existing medical applications, the most acceptable design and structure of our own application were identified. RESULTS: The developed "Urolithiasis" application is available for free download in Russian language versions in App Store (Apple, Inc.) and Google Play (Android market, Google, Inc.). It features the following sections: 1) "Take the test" (personalized calculation of the risk of kidney stone recurrence and providing relevant recommendations using ROKS nomogram), 2) "Water" (with reminders to drink water and automatic logging of the water intake), 3) "Food" (Nutrition facts on the content of calcium, oxalate, purine, protein, citrate and calories in common foods), 4) "My doctor" (in the future this option will allow for on-line communication with a patients physician), 5) "Feedback" (if the patient does not find the desired product or has a question - this section is for him/her). CONCLUSIONS: The smartphone application "Urolithiasis" in Russian may be recommended to patients with urolithiasis for improving the effectiveness of metaphylaxis.
