[Computer tomographic and sonographic demonstration of renal haematomas following percutaneous renal biopsy (author's
The incidence of post-puncture haematomas following percutaneous renal biopsy in 23 patients (24 punctures) is reported. The incidence of renal haematomas was 29.1%. The diagnostic value of computer tomography and sonography is discussed. Amongst small haematomas (less than 7 ml. blood), which could only be demonstrated by computer tomography, 8.2% were purely intrarenal, 8.2% were sub-capsular and 12.3% showed combined intrarenal, subcapsular and perirenal bleeding. The incidence of sub-capsular and perirenal haematomas of 20.5% is considerably lower than has previously been reported in literature.
