Percutaneous nephrolithotomy of staghorn calculi in patients by mini-tract and standard-tract / 中南大学学报(医学版)

ABSTRACT

OBJECTIVE@#To compare the outcome of mini-tract vs standard-tract percutaneous nephrolithotomy (PCNL) in staghorn calculi.@*METHODS@#Between May 2009 and May 2011, 122 patients with renal staghorn calculi were treated by PCNL. Fifty-six patients underwent mini-PCNL and the others underwent standard-PCNL. The therapeutic effect and complication of the 2 groups were compared.@*RESULTS@#The two groups had comparable demographic conditions. Although the operation time was significantly longer in mini-PCNL group [(126±24.5) min vs (98±18.9) min], there was no striking difference in hospital stay [(5.7±1.3) d vs (5.3±1.1) d], hemoglobin drop [(9.5±3.2) g/L vs (10.5±3.3) g/L], stone-free state before charge (91.1% vs 89.4%) and complications.@*CONCLUSION@#The efficacy and safety of mini-PCNL and standard-PCNL are not significantly different.
