A total of 86 consecutive patients who presented to the accident and emergency department with acute urinary retention due to prostatomegaly required catheterisation; 56 received suprapubic catheters and 30 were catheterised urethrally. Both groups were followed up for 3 years. Of the 30 patients catheterised urethrally, 12 (40%) developed urinary tract infections compared with 10 (18%) urinary tract infections in the 56 patients catheterised suprapubically. Five patients (17%) in the urethral group developed urethral strictures with no strictures in the suprapubic group. Two patients catheterised urethrally developed epididymo-orchitis and 1 developed septicaemia. None of the patients with suprapubic catheters developed these complications. Furthermore, 16 patients catheterised suprapubically underwent successful trial clamping of their catheter, whereas 7 patients required recatheterisation following removal of their urethral catheters. We recommend that the use of suprapubic catheters should become the preferred initial treatment for acute urinary retention.
Of 1,048 renal transplants performed between 1971 and 1990, transplant nephrectomy was performed in 86 (8.2%). Mean patient age was 33 years (range 3.8 to 66.5). Postoperative complications occurred in 60% of the patients, including wound infection in 20% and major hemorrhage in 4 patients. The external iliac artery was ligated in 4 patients. The incidence and severity of the complications were greater in patients with acute rejection. Four patients died: 1 of ischemic bowel and metastatic carcinoma, 1 of pulmonary embolism, and 2 of sepsis and disseminated intravascular coagulation. The nephrectomy rate increased significantly (p < 0.005) when cyclosporine A was initially introduced. Added care is necessary when new immunosuppressants are used. The majority of our failed transplants were left in situ without compromising overall patient well-being.
Peritoneal adhesions cause much long-term postoperative morbidity. This study evaluates the efficacy of polyethylene glycol (PEG) 4000 in reducing adhesion reformation after lysis. Adhesions were induced, by abrasion, in 111 Sprague-Dawley rats at a first laparotomy. At a second operation, 10 days later, these adhesions were graded and lysed, after which the animals received one of the following solutions intraperitoneally: 5 per cent PEG 4000 (n = 21), 25 per cent PEG 4000 (n = 23), 32 per cent dextran 70 (n = 22) or isotonic saline (n = 25), or were left as an untreated control group (n = 20). When the reformed adhesions were graded after a further 10 days 5 per cent PEG 4000 was found to be the only solution that inhibited adhesion reformation. The adhesions that reformed in the other four test groups were significantly worse than when they were first graded (P less than or equal to 0.033 for all groups). Therefore 5 per cent PEG 4000 may be useful in clinical practice for the reduction of adhesion formation after lysis.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
