ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the risk factors of post-renal biopsy bleeding (PBB).</p><p><b>METHODS</b>We retrospectively analyzed the clinical data of 1 262 patients who received ultrasound-guided biopsy of native kidney at our hospital from January 2005 to December 2006.</p><p><b>RESULTS</b>The overall incidence of PBB was 30.3% (383/1,262), among which the incidence of hematoma was 29.4% (371/1,262) (the percentages of less and more than 5cm were 73.9% and 26.1%, respectively) while that of gross hematuria was only 1.3% (17/1,262). The incidences of minor, intermediate, and major bleeding complications were 21.4% (270/1,262), 8.4% (106/1,262), and 0.6% (7/1,262), respectively. In seven patients with major bleeding complications, six had renal disease secondary to rheumatic disease (lupus nephritis, n = 5; scleroderma crisis, n = 1), while the other one had IgA nephropathy (Lee's classification V). The risk of PBB was relatively higher in women and younger patients.</p><p><b>CONCLUSIONS</b>Patients with chronic connective tissue diseases are vulnerable to severe PBB complications. A close monitoring of these patients is necessary.</p>
