ABSTRACT

Introduction: renal graft biopsy is the most important tool for the diagnosis of renal pathology. Objective: to describe the experience kidney transplant biopsy with tangential technique using an ultrasound-guided cutting needle. Material and methods: a retrospective review of 89 patients with kidney transplant that required eco-guided biopsy type Trucut with cortical tangential approach technique using automated devices with 18G needles for evaluation of such technique, as well as it success rates for obtaining tissue samples and possible complications that may occur. Results: the cortical tangential technique identified a total of 89 samples, 72 samples (80.9%) were considered satisfactory, as for minimum samples 7 cases (7.9%) and 10 inadequate (11.2%) were found. With the cortical tangential approach, excellent results were obtained, finding satisfactory samples in 32 patients with only one specimen, 33 patients with two specimens and only 7 patients required obtaining a third specimen. There was no distinction between age and sex in the patients evaluated. Only 10 patients (11.2%) had complications, the most commonly encountered being hematuria. Conclusion: the cortical tangential approach is an useful and adequate technique for obtaining a satisfactory histopathological sample, without significant complications.
