Minimally invasive treatment for multiple calculi in homolateral kidney and ureter / 中国微创外科杂志

ABSTRACT

Objective To investigate surgical techniques of minimally invasive management for multiple calculi in the kidney and ureter. Methods Combined use of ureteroscopic lithotripsy(URSL) and minimally invasive percutaneous nephrolithotomy(MPCNL) was carried out in 21 patients with multiple calculi in homolateral kidney and ureter between January and October 2005 in this hospital.Results Percutaneous nephrostomy was required before the stone removal in 2 patients with pyonephrosis.Of the remaining 19 patients,all the ureteral calculi were completely removed on one session.And the renal calculi were removed by single session in 13 patients,by secondary percutaneous nephrolithotomy in 3 patients,and by tertiary nephrolithotomy in 2 patients.The combination treatment failed in 1 patient because of stricture of uretero-vesical orifice and a conversion to open surgery was needed.Conclusions Combination use of ureteroscopic lithotripsy and minimally invasive percutaneous nephrolithotomy is effective for the treatment of multiple calculi in homolateral kidney and ureter,offering advantages of minimal invasion,rapid recovery,and few complications.
