title: Percutaneous renal biopsy using Monopty needle.
abstract: Forty six percutaneous renal biopsies (thirty one native and fifteen transplant kidneys) were performed using the Monopty needle, compared with equal number of biopsies performed using the Travenol Tru-cut needle. The core length of samples obtained ranged from 3-16 mm using Monopty and 5-13 mm using Tru-cut. Adequate tissue was obtained in 65.5% and 80.4% of cases with the use of Monopty and Tru-cut respectively. Both the needles gave equal number of reuses. The use of Tru-cut needle was associated with serious complications like gross haematuria requiring blood transfusions and perinephric haematoma in ten cases whereas only two cases developed haematuria when the Monopty needle was used. In view of its greater safety we have switched over to using the Monopty needle for percutaneous renal bipsies.
