Impact of Prior Surgery on Success Rate and Morbidity of Percutaneous Stone Manipulation

Almost one-third (32%) of 221 kidneys manipulated percutaneously for calculi had had previous open procedures. Tract dilation was more difficult in these kidneys, and there was a statistically significant increase in the frequency of cases requiring multiple manipulations to rid them of calculi (14% vs. 7% in those without previous renal surgery). There also was a statistically significant difference in the number with retained stone fragments (13% vs. 8%). Although there were increases in the frequency of bleeding necessitating transfusion, procedure time, and complications, these differences were not statistically significant. We concluded that percutaneous stone removal is only minimally compromised by previous open renal surgery. © 1987, SDAMAL. All rights reserved.
