Quality of life of patients with kidney stones

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.
