Abstract:
Objective To evaluate the learning curve in percutaneous nephrolithotomy under the guidance of B ultrasonography.Methods From January 2006 to July 2007,totally 60 cases of percutaneous nephrolithotomy were performed under the guidance of B ultrasonography by a single urologist.The patients were divided into 6 groups according to the date of the operation(10 cases in each).The time for setting the renal access and the stone-free rate were compared among the groups.Results The time for setting the renal access was(15.0?2.7),(14.0?2.1),(10.2?1.2),(5.8?0.7),(7.5?1.2),and(6.6?0.9)minutes respectively in group 1 to 6.ANOVA analysis showed significant difference among the groups(F=5.734,P=0.000).Significant difference was detected between groups 1 and 4(q = 5.655,P
