Dynamic CT scans were conducted on 94 persons who had been randomly selected among the patients and the volunteers. The test results were used to obtain the time-density curve. A part of the subjects (20 cases) underwent the renogram examination for the comparative studies. The cortico-aortic (CA) ratio derived from the time-density curve demonstrated good correlation between the dynamic CT and...

OBJECTIVE To report our experience with open dismembered pyeloplasty for uretero-pelvic junction obstruction. METHODS Retrospective study was conducted in the Department of Urology, Jinnah Postgraduate Medical Centre, Karachi for a period of five and half years from May, 2006 to December, 2011. All patients with uretero-pelvic junction obstruction were entered into a database to record patien...

Congenital diaphragmatic hernia (CDH) is a rare anomaly with a reported incidence of 1 in 16,000 populations. It may be associated with herniation of stomach, intestinal loops, spleen, and kidney through a chest wall defect. We report a case of a 1 year old male child who presented with recurrent fever, occasional chills and rigor of 4 months duration. Left kidney was non visualised on ultrasou...

We compared single-sample methods, proposed by Russell et al. and Bubeck et al., and camera-based methods in calculating 99mTc-MAG3 clearance, and determined camera-based methods that provide estimates comparable to those measured by the Russell method. Twenty-one patients underwent 99mTc-MAG3 renal scintigraphy, and clearance was measured by the Russell method and Bubeck method. Various renogr...

Our previous study investigated the effect of a single dose of NSAID diclofenac, which is the most commonly used to relieve kidney pain, on the renograms using radiopharmaceuticals. The objective of this study is to examine the effect of long-term use of diclofenac on renography. A baseline study (control) was done by injecting the rabbits Tc-DTPA and a renography was performed. Two days later ...

INTRODUCTION Accurate determination of donor kidney function has important long-term implications for both donor health and recipient outcome. Many centers use 24 hour urinary creatinine clearance or creatinine-based GFR estimations to assess kidney function but their performance when compared with GFR measurements by isotope clearance remains inconclusive. We assessed the performance of creati...
