ABSTRACT
Objective To evaluate the occurrence and management of complications following mini- mally invasive percutaneous nephrostolithotomy (MPCNL).Methods The data of 436 cases of MPCNL from December 2001 to March 2005 were reviewed,including 249 male cases and 187 female cases.Their age ranged from 14 to 71 years with a mean of 41.6 years.Of the 436 cases,314 cases had simple nephrolith- iasis,79 had nephrolithiasis combined with upper ureterolithiasis,27 had unilateral upper ureterolithiasis,and 16 had bilateral upper ureterolithiasis.Results Among the 436 cases of MPCNL,complications occurred in 27 cases (6.2%).Of the 27 cases,5 had massive hemorrhage,which was cured by closing meatus of nephric fistula,cleaning out the blood clot within the bladder with instrument and transfusing blood;2 cases had pleural effusion,11 cases had hydroperitoneum,8 eases had renal perforating injury,and they were cured by puncture and drainage;1 case had pyocalix,which was cured by using effective antibiotics,re-punc- turing kidney and postponing pulling out the fistula catheter.Conclusions MPCNL is a minimally inva- sire operation.However,it has obvious risk if the surgeon's skill is not proficient.The improvement in the pre- vention and management of complications can promote the application of this procedure.
