ABSTRACT

Clinical data of 53 patients with lower caliceal stone during August 2005 and March2007 were analyzed retrospectively.The stones were 11-35 mm in diameter.Under the guidance of X-ray.single renal tract parallel to the lower caliceal for percutaneous nephrolithotomy was established.The procedures were successful in all the patients.Fifty patients were stone free after first minimally invasive pereutaneous nephrolithotomy(MPCNL),2 were stone free following second MPCNL,1 saw residual small stones clear off spontaneously during the follow-up period.Operative time was 65-162 minutes.and blood loss was 10-200 ml.No severe complications or death occurred.MPCNL may be related with minimal invasion and fewer complications,thus provides an effective and safe way of lower caliceal stone treatment.
