Percutaneous Nephrolithotomy In Patient With Open Nephrolithotomy History

Purpose Does a history of open nephrolithotomy affects the efficacy and morbidity of percutaneous nephrolithotomy ? The answer is remains unsettled .The aim of this study is to determine the effects of previous open nephrolithotomy on the results and morbidity of subsequent percutaneous nephrolithotomy (PCNL). Patients and Methods Between October 2005 and November 2007, 72 patients underwent PCNL at our institution. We compared the patients who had had previous open surgery on the same kidney (group A; n= 35) with those who had had no previous surgery (group B; n=37). The two groups did not differ significantly in age (35.2 v 33 years), gender distribution, stone burden (1.6cm v 1.7 cm), stone number, or laterality, hydronephrosis. Operative time, hospital stay, success rate, and intraoperative bleeding and postoperative transfusion, infection rate, the number of PCNL, total expenditure, were compared. Results Intraoperative bleeding volume was 161ml and 100.7ml in group A and B and the postoperative transfusion(bleeding) was 9/35 vs 2/37 in group A and B. Total expenditure was 14510$ vs 12450$.There were no differences in operating time, hospital stay and the number of PCNL, or the stone-free rate. Conclusions Except the Intraoperative bleeding and postoperative transfusion. The morbidity and efficacy of PCNL are similar in patients who have had previous open nephrolithotomy and those having no previous surgery. Previous open surgery does not appearently affect the success of PCNL.
