Abstract
Objectives
Our objective was to investigate the effects of previous open nephrolithotomy on technical features, outcomes, and morbidities of subsequent percutaneous nephrolithotomy (PCNL).
Methods
One hundred and sixty patients underwent PCNL between December 2004 and September 2006. The patients were divided into those who had previous open nephrolithotomy on the same kidney (group 1: 55 patients) and those who had no previous open surgery (group 2: 105 patients). Technical features encountered during operation and outcomes were compared between groups.
Results
There were no significant differences between groups with respect to mean age (group 1: 42.6 ± 10 years vs. group 2: 45.5 ± 9.6 years), body mass index (24.8 ± 2.11 vs. 24.6 ± 2.14), and stone burden (385.6 ± 140.6 mm2 vs. 401.05 ± 142 mm2). In group 1, 28 and 27 stones were located in the right and left kidney, respectively, whereas the location was 51 and 54 for the right and left kidney, respectively, in group 2. When the groups were compared, the mean operative time was significantly longer (155 ± 30 min vs. 137 ± 30 min) in group 1. But there was no significant difference with respect to requirement for secondary intervention (11% vs. 10%). Sepsis developed in two patients in group 1 and one patient in group 2. One patient in group 1 died due to septic shock. Ten (18.2%) patients in group 1 and 13 (12.4%) patients in group 2 required blood transfusion.
Conclusions
When PCNL is performed after previous open nephrolithotomy, the operative time lengthens. But there is no difference with respect to success rate and morbidities.
