A trial of the value of diuresis renography in equivocal upper urinary tract obstruction is presented. Fifty-two patients were examined by standard renography and renography under a diuretic provocation. The results indicate that the technique is of considerable value in making the vital distinction between dilatation on the excretion urogram due to(More)
X-ray fluorescence analysis provides a simple method of measuring glomerular filtration rate from the clearance of ordinary unlabeled radiographic contrast media. To measure the accuracy of iohexol clearance using a clinically simple 2-sample single injection technique, a comparison was made in 30 patients with classical continuous infusion techniques for(More)
OBJECTIVE To analyse current practice in the management of acute urinary retention (AUR) secondary to benign prostatic hyperplasia (BPH) in the UK, and to assess how much of this is evidence-based. METHODS In all, 410 consultant urologists practising in UK hospitals were sent a questionnaire about the management of AUR secondary to BPH. Data were(More)
A new method to evaluate patients with equivocal obstruction of the pelvioureteral junction is described. It involves the performance of a standard 131iodine-hippuran renogram followed by a second renogram 3 minutes after an intravenous injection of the diuretic, frusemide. When the 2 results are inspected together it is found that the patients can be(More)
OBJECTIVES To examine the durability of open pyeloplasty for pelvi-ureteric junction obstruction. PATIENTS AND METHODS The records of 56 Anderson-Hynes pyeloplasties undertaken by two surgeons between 1981 and 1994 were examined. Attempts were made to trace all patients and for them to undergo diuretic renography to examine the current status of the(More)
PURPOSE We compared the efficacy of Entonox (BOC Gases, Manchester, United Kingdom), a mixture of 50% nitrous oxide and oxygen, with periprostatic infiltration of 1% lidocaine to provide analgesia during transrectal ultrasound (TRUS) guided biopsy of the prostate. MATERIALS AND METHODS The study included 235 consecutive men undergoing TRUS guided biopsy(More)
The cardiovascular effects of relief of obstruction were examined in 21 patients with painless urinary retention and hydronephrosis and hydroureter associated with hypertension (diastolic blood pressure 95-120 mm Hg, mean 107, 11 patients), severe peripheral oedema (8 patients), raised jugular venous pressure (5 patients), or clinical evidence of pulmonary(More)
In a prospective study of high pressure chronic retention, a newly defined disorder of the urinary tract, 21 patients were analysed for their mode of presentation and urodynamic, renographic, and operative findings. High pressure chronic retention is characterised by late onset enuresis, a tense, palpable bladder, hypertension, and progressive renal(More)
