[Surgical treatment of coral nephrolithiasis: analysis of complications].

Coral nephrolithiasis (CN) patients treated surgically in Research Institute of Urology and hospital N 47 from 2005 to 2008 were divided into 5 groups by treatment: PCNL, PCNL+extracorporeal lithotripsy (EL), EL, open interventions, EL of the residual concrements after previous open operations. Most complications were observed after EL and they were caused by evacuation of many fragments. PCNL caused in some cases massive hemorrhage stopped by conservative methods. Open operations can effectively remove concrements in one stage but sometimes entail such severe complications as damage to adjacent organs, pleura or abdomen, hemorrhage, exacerbation or progression of chronic pyelonephritis. Results of combined surgical interventions (PCNL+EL) and EL of residual concrements after open surgery are comparable with those of EL as monotherapy if the schedule of repeat sessions is observed and saving regimens of fragmentation are used.
