Efficacy and safety of percutaneous nephrolithotomy in the treatment of kidney calculi

Introduction. Urolithiasis is one of wide-spread in the urological diseases distribution and considered socially significant one. In various regions of Russia, Republic of Bashkortostan is one of them, the endemicity of this pathology is revealed and statistically proved. The formation of stones in the urinary system is caused by a number of social and genetic factors. Nowadays, there are many methods of treatment of urolithiasis. According to the National recommendations and Guidelines of the European Association of urology, the choice of operational intervention method depends on the size of the concrement and the form of nephrolithiasis. despite the low invasiveness of surgical treatment, 10-15% end up in sequela. Taking into account the mentioned above it is important to analyze efficacy and safety of nephrolithotripsy through one’s own experience. Aim: To evaluate the efficacy and safety of nephrolithotripsy in various forms of nephrolithiasis. Materials and methods. The study group included 365 patients who underwent percutaneous nephrolithotripsy in the clinic of the Bashkir state medical University. In the preoperative period, patients were examined according to the standard scheme, according to the results (localization, size of concrements), the most suitable access for percutaneous nephrolithotripsy was selected. In the preoperative period, patients were examined according to the standard scheme, according to the results (localization, size of concrements), the most suitable access for percutaneous nephrolithotripsy was selected. The efficacy of the surgical treatment was evidenced by the complete removal of concrements or calculi up to 4 mm. Clavien-dindo classification served as a scale of evaluation of postoperative complications. Results. By the gender type-men 175(47.9%), women 190 (52.2%). The age of patients was from 22 to 83 years. The average size of the calculus was 2.4 cm (0.8 - 7.8 cm). The average operation time was 83 min (23-258 min). The average bed day was 5.6. According to the classification of Clavien-dindo complications of 1 degree were observed in 123 (33.7%) of patients, 2 degree in 2 (0,5%) patients, 3a degree 1 (0.3%) and 4b degree was observed in 1 (0,3%) patient, there were no complications of 5 degree. Summary. Percutaneous nephrolithotomy has come out as one of the highly effective and safe methods of treatment of nephrolithiasis.
