Outpatient percutaneous renal biopsy in high risk patients

The safety of outpatient percutaneous renal biopsy is controversial. 101 consecutive renal biopsies performed over a 5-year period were reviewed. Ultrasound localization and semiautomated biopsy needle technique were utilized. Outpatients were observed for 8h with a repeat Hct done 6h post-biopsy. 66 patients had outpatient biopsy (only one patient was specifically admitted for biopsy). 5/66 outpatients, including 2/18 patients with renal insufficiency (Screat > 2.5) were observed overnight because of a fall in Hct > 3% and discharged the following day with stable Hcts. 26/66 had transplant biopsies and 2/66 had bleeding times > 10 min which corrected with DDAVP prior to uncomplicated biopsy. None of these patients required overnight observation. These data suggest that outpatient biopsy can be utilized safely in patients with renal insufficiency, renal allografts, and correctable bleeding diatheses.
Comment: Outpatient renal biopsy is now commonly performed. In many centers, overnight outpatient observation (< 24h) is employed, although this may not be necessary since substantial bleeding post-biopsy is generally obvious within a few hours of completing the procedure.
