[Applicable value of ultrasound-guided renal biopsy in diagnosis of kidney diseases].

OBJECTIVE

To explore the applicable value of ultrasound guidance in percutaneous renal biopsy.

METHODS

168 patients with kidney diseases underwent ultrasound-guided renal biopsy. Pathological examination was conducted. Predictors of successful rate were assessed by multivariate logistic regression analysis.

RESULTS

Successful biopsy was achieved in 157 of the 168 patients with a success rate of 93.45%. Satisfying results were obtained from 143 of the 157 samples and normal renal tissues were reported in 14 samples. No serious adverse events were observed in this study. The successful biopsy rate of female patients was 89.16%, significantly lower than that of the male patients (97.65%, P < 0.05). Age, puncture times, thickness of renal cortex, and type of clinical diagnosis were not significantly correlated with the successful rate of biopsy.

CONCLUSION

Ultrasound-guided renal biopsy is a kind of safe diagnostic method for kidney disease. The successful rate of renal biopsy in females is lower than that in males.
