ABSTRACT

Objective：To further evaluate clinical application of ultrasound guided automatic biopsy technique in diffuse renal diseases.

Methods：Epidem io logical study of large samples with multiple factors and multiple levels was adopted.

Results：Samp ling success rate obtained with automatic renal biopsy technique was much higher than that of manual biopsy groups (91.00% and 66.67% , P < 0.01) .Sampling success rate with automatic renal biopsy was not related to the length of tissue-core and the number of biopsy passes (P < 0.05). The complicat ions of automat ic renal biopsy group were significantly lower than that of manual biopsy group (7.44% and 66.67% respectively, P < 0.01) . We found that the independent factors in many clinical factors which had influence on complications of renal biopsy were shown as follows: acute renal failure and hypertension (diastolic pressure > 95 mmHg) and nephrotic syndrome.

Conclusions：U ltrasound guided automatic biopsy technique with biopsy gun (18G) in diffuse renal diseases has more advantages and less comp lications, and can substitute for manual renal biopsy (14G).
