Objective . To study the nephroprotective effect of lercanidipine and its influence on creatinine clearance and cytokine damage in patients with urolithiasis with obstructive uropathy. Material and methods. Of 96 patients evaluated, 66 were diagnosed with kidney stones in the ureteropelvic segment and obstructive uropathy, which was then treated with percutaneous nephrostomy. All 66 patients were given antibacterial and anti-inflammatory therapy to prevent postoperative infections, but in addition, 33 were treated with lercanidipine, 10 mg per day. IL-8, VEGF, MCP-1, G-CSF, and GM-CSF concentrations in the urine were determined by solid-phase ELISA. The estimated glomerular filtration rate was calculated using the CKD-EPI formula. All studies were done preoperatively and on days 7, 14, 21, and 28 after nephrostomy. A control group consisted of 30 people with kidney stones without sings of obstruction. Results. In the patients with obstructive uropathy, a correlation was found between VEGF, IL-8, and MCP-1 concentrations in the urine and the serum creatinine and estimated glomerular filtration rate. Patients in the lercanidipine group had a faster decrease in IL-8, VEGF, MCP-1, and GM-CSF concentrations in the urine and improved renal function compared with patients who did not receive lercanidipine. By day 21 after nephrostomy, the lercanidipine group had values comparable with the control group, whereas the group not treated with lercanidipine did not achieve similar values until day 28. Conclusion. The third generation calcium channel blocker lercanidipine is nephroprotective in patients with obstructive uropathy.
