title: [Treatment of calculous pyonephrosis with percutaneous nephrolithotomy via the standard access].
abstract: OBJECTIVE
  To investigate the feasibility of treatment for calculous pyonephrosis with first stage percutaneous nephrolithotomy under the standard access.
  
  
  METHODS
  Thirty-six cases of calculous pyonephrosis and 36 cases of urolithiasis with no pyonephrosis were treated by percutaneous nephrolithotomy. In the nephrostomy, the caliber was dilated to F24. All the operations were preformed through the EMS lithotrity system. The intrapelvic pressure was detected in the operation. The hemoculture before and after operation, the germi culture of urine, and the temperature and blood leucocyte changes after operation were recorded. All the patients were treated by antibiotics before and after the operation.
  
  
  RESULTS
  All the patients were treated successfully. The average intrapelvic pressure were 23.2 cmH(2)O in non-pyonephrosis group and 22.8 cmH(2)O in pyonephrosis group. Both of the groups had 1 case of transient bacteremia after the operation. No significant difference was found in the other indices between the two groups.
  
  
  CONCLUSIONS
  EMS lithotrity system is safe and feasible for treating calculous pyonephrosis with stage I percutaneous nephrolithotomy via the standard access.
