Extracorporeal shock wave lithotripsy-induced perirenal XXXX .

@entity1 @entity101 @entity548 @entity1410 @entity16237
Subcapsular or perirenal @entity548 is the most commonly experienced adverse effect directly attributable to externally applied shock waves. The first consecutive 3,620 extracorporeal shock wave lithotripsy treatments with the @entity16237 Dornier lithotriptor at our institution resulted in 24 @entity1410 in 21 @entity1 , for an incidence of 0.66 per cent. Various factors associated with treatment were examined. The number of shock waves (up to 2,000) and voltage up to 24 kv. did not correlate with the development of @entity1410 . Coagulation studies were normal in all @entity1 with @entity1410 . There was no correlation of @entity1 size and weight, or stone size, number or location with the occurrence rate of perinephric @entity1410 . @entity1 with pre-existing @entity101 , particularly those with unsatisfactory control of @entity101 , had a significantly increased incidence of perinephric @entity1410 . The incidence of @entity1410 in @entity101 @entity1 was 2.5 per cent and it increased to 3.8 per cent in @entity1 with unsatisfactory control of @entity101 . Therefore, pre-existing @entity101 is a significant risk factor in the occurrence of post-extracorporeal shock wave lithotripsy @entity548 . The incidence of perinephric @entity1410 also was increased in @entity1 with pre-treatment urinary tract infection and those who underwent simultaneous bilateral treatment. Management of post-extracorporeal shock wave lithotripsy @entity548 generally is conservative although a third of the @entity1 required transfusion.
