Transurethral contact electroimpulse ureteropyelolithotripsy

Transurethral contact electroimpulse ureteropyelolithotripsy (TCEUT) was conducted in 161 patients aged 18 to 84 years (mean age 47 +/- 14 years) admitted to the urological department of Zhukovsky city hospital in 2006-2009. Female/male proportion 1.4:1. Overall efficacy of TCEUT was 98%, the concrement was destructed completely during the first TCEUT session in 98%, partially in 2% cases. The method was feasible in all the patients if the instrument could reach the concrement. Duration of the session providing complete elimination of the concrements varied from 1 to 6 months.Contact electroimpulse ureterolithotripsy is conducted with single impulses beginning with low energy (0.45 J). Contact electroimpulse pyelolithotripsy requires a higher initial impulse energy (0.6 J). TCEUT is a highly effective method of the treatment of concrements of the upper urinary tract. Side effects were registered in maximum 5%. Long-term existence of the concrement in the urinary system raises the risk of intraoperative complications.
