Abstract:
Objective To investigate the clinical outcomes of minimally invasive percutaneous nephrolithotomy(MPCNL)in the treatment of lower caliceal calculi.Methods We retrospectively re- viewed the clinical outcomes and complications of 33 patients who underwent MPCNL for lower caliceal cal- culi from March 2001 to April 2005.The average diameter of the calculi was 2.8 cm.Single tract nephrosto- my was performed in all 33 cases;among them renal access was obtained through a middle calyx in 10 cases and a lower calyx in 23.Nine cases had F14 renal access;and 24 cases,F16.Results Of 33 cases,28 (85%)achieved stone-free at 1 session.A second-look was needed in 3 cases due to intraoperative bleed- ing;ESWL,in 1 case with residual,calculi;no treatment,in 1 case with residual calculi＜4 ram.The mean operative time was 93 min;mean blood loss was 113 ml;mean hospital stay was 11 d.Blood transfusion was needed in 1 patient who suffered from hepatic cirrhosis preoperatively;another experienced severe bleeding 7 d after operation and was cured with hyperselective spongia gelatinosa embolization of the renal artery.Fol- low-up was available in 19 cases for 2-48 months,and no recurrence of renal calculi was noted.Conclu- sions Minimally invasive percutaneous nepbrolithotomy has advantages of safety,less invasion,and easy re- covery for the treatment of lower caliceal calculi.
