Relevance. In 2013, the Wisconsin Stone Quality of Life Questionnaire (WISQoL) was developed a specific tool for assessing the quality of life (QoL) in patients with urolithiasis. Aim. To determine the possibility of using the WISQoL and SF-36 questionnaires to study the treatment results of patients with kidney stones. Materials and methods. The study included 218 patients with nephrolithiasis. Patients were divided into 2 groups: the first the size of the stone up to 10 mm and the second from 11 to 20 mm. At the first stage, the efficacy of treatment patients by the extracorporeal shock wave lithotripsy (ESWL) and percutaneous nephrolitholapaxy (PNL) 1 week, 1 and 3 months after surgery was compared. Questionnaires were used to study factors affecting the QOL of patients, including: gender, age, number, density and size of stones, hydronephrosis, stone free rate (SFR), type of surgery. At the next stage, the dynamics of changes in scores for the domains of questionnaires at different stages of treatment was evaluated. Results. The efficacy of treating kidney stones up to 1 cm in size after 3 months with ESWL was 86,1% and PNL 94,4 %, while stones up to 20 mm using ESWL 73,4% and percutaneous techniques 90,6%. Gender, age, stone size, SFR affected the QoL of patients with nephrolithiasis, while the number and density of stones, the presence of hydronephrosis and the type of operation were not significant. Patients 1 week after PNL had lower QoL scores in the domains of social impact and impact on vitalyty of WISQoL and mental heals of SF-36. After 1 month, these changes were determined only in the social impact domain and completely regressed by the 3rd month. Conclusion. SFR after ESWL and PNL in the first group is comparable, in the second group, percutaneous operations were 17,2% more effective. Male gender, age up to 40 years, stone size more than 1 cm, and also not reached SFR negatively affects patients with nephrolithiasis. Compared with ESWL and PNL is accompanied by the worst dynamics of QOL scores only 1 week after the operation; upon further observation, negative changes are leveled.

Introduction. Simple kidney cyst is a common disease that may need surgical treatment for pain, hypertension and kidney obstruction. Long term results of kidney cyst treatment need further investigation. The aim of the study was to assess patient complaints and kidney ultrasound sonography data in patients in a long term after percutaneous cyst aspiration (PCA) with sclerotherapy and laparoscopic decortications of the cyst wall (LDC). Patients and methods. In this retrospective study clinical data of 891 patients (277 (31,1%) men and 614 (68,9%) women, mean age 61,8 years) with simple kidney cysts operated by PCA and LDC (754 (84,6%) and 137 (15,4%) patients respectively) due to back pain, hypertension, big cyst size and obstruction of urine flow from the kidney was analyzed. Control survey and ultrasound sonography scans were performed in 80 (18,1%) patients, including 40 (50%) patients after PCA and 40 (50%) patients after LDC. Results. At control sonography kidney cysts were found in 32(80%) and 27(68%) patients after PCA and LDC respectively, but median cyst size decreased. Compared to PCA, LCD more often resulted in complete disappearance of cysts and also caused more prominent cyst size reduction (p = 0,027), however the lengths of stay (LOS) was longer after LDC (p = 0,005). After surgery the back pain and hypertension persisted in many patients, while the flow of urine from the kidney normalized in all patients. Conclusions. LDC compared to PCA was more effective in complete cyst removal and caused more significant decrease of cyst size. The LOS was longer after LDC, both LDC and PCA were effective in regaining urinary flow from the kidney. Back pain and hypertension should be considered relative indications for surgical treatment of kidney cysts. (For citation: Korneyev IA, Кiselev АО, Ishutin EJu, et al.

Abstract. The clinical efficacy and safety of the use of percutaneous techniques in the treatment of kidney stones in 72 servicemen were studied. All percutaneous operations were performed by one operating team. It was found that percutaneous urolithiasis surgery was effective in 88.9% of people. Stone free rate was achieved in 83,8% of military personnel undergoing standard percutaneous nephrolitholapaxy and in 94.3% of patients undergoing minipercutaneous nephrolitholapaxy. With stones larger than 2 cm, the effect was observed in 81.8% of cases with standard surgery and in 96% of patients with mini-percutaneous approach. Percutaneous interventions in military personnel with stones larger than 2 cm were effective in 84,6% of patients with standard surgery and in 90% with mini-percutaneous access. Complications according to the Clavien-Dindo classification were found in 29,1% of servicemen: in 20,8% of cases of standard nephrolitholapaxy and in 8,3% of minipercutaneous nephrolitholapaxy. The bulk of the complications were Grade III 20,8%. Grade III IV were determined less frequently in 8,3% of cases. Urosepsis (Grade IV b) and death (Grade V) were not observed in our study. Duration of labor losses for conscripted servicemen were about 17 days, for contract servicemen when performing standard nephrolitholapaxy 12,8 days, for military personnel with minipercutaneous nephrolitholapaxy 11,2 days. The dismissal rate among conscripts was 18,2%. There were no contractual servicemen who were dismissed from the ranks of the Armed Forces of the Russian Federation, however, 14,7% of servicemen who underwent a standard operation and 11,1% of patients who underwent mini-percutaneous nephrolitholapaxy after surgery needed sick leave for a period of 15 days. In general, percutaneous techniques are common and effective methods of surgical treatment for military personnel suffering from urolithiasis. Mini-percutaneous approach for nephrolitholapaxy is safer than the standard approach, but it is less effective for coral calculi. Percutaneous methods for removing kidney stones are associated with a low rate of dismissal and short recovery times for military personnel.
