Abstract
- Purpose
The incidence of renal hemorrhage and the transfusion rates in patients undergoing balloon or Amplatz fascial dilation of the nephrostomy tract during percutaneous nephrolithotomy (PCNL) were compared.
Materials and Methods
The medical records of 100 patients who underwent PCNL were reviewed. The nephrostomy tract was dilated with either a balloon (53 patients) or Amplatz sequential (47 patients) dilators. The time required for nephrostomy tract dilation, the stone burden, perioperative blood hemoglobin level and blood transfusion rates were compared between the two groups.
Results
Of the 47 patients that underwent percutaneous renal Amplatz dilatation, 14 (29%) required a blood transfusion, compared to only 7 of the 53 (13%) that underwent balloon dilation. The difference in the transfusion rates between the 2 groups was statistically significant (p=0.04). The time required for nephrostomy tract dilation was also shorter with balloon than Amplatz dilation (6.5 versus 12.3 minutes, p=0.02).
Conclusions
Balloon dilation led to less renal hemorrhage and lower transfusion rates compared to Amplatz dilation during PCNL. Additionally, the time required for nephrostomy tract dilation was shorter with balloon dilation.)
