CT guided percutaneous renal biopsy versus ultrasound guided for obtaining adequate tissue.
OBJECTIVE To study the diagnostic yield of specimen obtained by percutaneous renal biopsy (PRB) under CT guidance and Ultrasound (US) guidance. METHODS This study was conducted at the department of Nephrology at Liaquat National Hospital and Dr. Ziauddin Hospital, Karachi. Renal biopsy specimens obtained between January 2007 and September 2009 were studied for number of glomeruli obtained. In...
متن کاملA novel technique for peroral direct cholangioscopy.
Article Direct cholangioscopy has been possible since the 1970’s (1) but reliable intubation of the common bile duct (CBD) and second order ducts has limited the applicability of the technique. One of the limitations to accessing the ducts is the acute angulation between the duodenum and the CBD (2). Various methods have been employed to access the ducts including mother-and-baby endoscopes and...
متن کاملUltrasound guided synovial biopsy using portal and forceps.
OBJECTIVE To describe a new method for taking a synovial biopsy specimen under ultrasound guidance using portal and forceps. METHODS Percutaneous ultrasound guided biopsy was performed for 37 patients with mono- or polyarthritis as outpatients. A portal to a planned area was built using a needle, guiding wire, and dilators, through which forceps could be inserted and samples taken. Biopsy sam...
متن کاملClinical Evaluation of the Peroral Cholangioscopy Using a New Videoscope
Peroral cholangioscopy (PCS) has been performed in 22 cases using XCHF-B200 (Olympus Optical Co.) since June 1995 and in 77 cases using CHF-B20 (Olympus Optical Co.) after EST from Jan. 1989. XCHF-B200 has a longer rigid portion of distal end and a smaller channel diameter than CHF-B20. The successful rate of PCS using XCHF-B200 (82%) was lower than that of CHF-B20 (89%). The vascular pattern a...
متن کاملA novel technique for biliary biopsy using the sheath of a plastic stent and a non-return valve.
Endoscopic transpapillary biopsy has been widely performed for the diagnosis of biliary disease. Direct-vision biliary biopsy using peroral cholangioscopy has been reported to be very useful [1–4]. At centers where peroral cholangioscopy is unavailable, biliary biopsy can be performed under fluoroscopic guidance. It is however sometimes difficult to obtain adequate biopsy specimens owing to iss...
