Background: The aim of this study was to investigate specific bleeding volume
after percutaneous renal biopsy (PRB) and the correlation between bleeding volume
and clinical parameters. Methods: A retrospective study of 252 consecutive
patients (153 male patients and 99 female patients) who underwent PRB at the
Department of Nephrology, Japanese Red Cross Ishinomaki Hospital, between July
2013 and January 2016 was conducted. PRB was performed under ultrasound guidance
using an automated spring-loaded biopsy device and a 16-cm, 16-gauge needle.
Patients underwent computed tomography (CT) the day after PRB. Bleeding volume
after PRB was evaluated using reconstructed CT data. Results: The median bleeding
volume after PRB was 38?mL (25th-75th percentile, 18-85?mL), with ?4 punctures
identified as a risk factor for massive bleeding. The incidence rates of
macrohematuria, transient hypotension and bladder obstruction were 14.3, 8.7 and
4.7%, respectively. Post-PRB blood transfusion and intervention were required in
4.7 and 0.8% of patients, respectively. Conclusion: Although it is difficult to
assess the risk for massive bleeding prior to PRB, we do provide evidence of a
specific increased risk with ?4 puncture attempts, and recommend careful
follow-up of these patients.
