BACKGROUND Ureteral stenosis is the most common urologic complication of renal transplantation. Preferred management options for this complication vary among centers. Ureteral stenosis occurred in 24 (3.4 percent) of 692 consecutive renal transplants. The diagnosis was confirmed by antegrade pyelography after ultrasonography in all instances. An attempt was(More)
Absorbable and non-absorbable suture materials were evaluated for calculi formation and tissue reactivity in the rabbit bladder. Five-O chromic, polydioxinone and polypropylene sutures were used to close cystostomies made in New Zealand white rabbits. Bladders were evaluated at 15, 30, 60 and 90 days. Calculi formed on all sutures tested and the persistence(More)
We performed a systematic review of the literature on medical noncompliance after kidney transplantation in the cyclosporine era. We wished to define commonalities that may help the clinician identify patients for early intervention. We found that patients who were at a higher risk of noncompliance after kidney transplants were younger, female, unmarried,(More)
The main problem of therapeutic efficiency lies in the crossing of cellular membranes. Therefore, significant effort is being made to develop agents which can cross these barriers and deliver therapeutic agents into cellular compartments. In recent years, a large amount of data on the use of peptides as delivery agents has accumulated. Several groups have(More)
Patients with insulin-dependent diabetes who receive pancreas/kidney transplants lose their need for insulin injections, but they become hyperinsulinemic and insulin resistant, and sometimes develop noninsulin-dependent diabetes mellitus. The reason for the insulin resistance is not well understood. Specifically, it is not known whether they become(More)
Progesterone and estradiol are metabolized in the liver and are elevated in patients with cirrhosis. Progesterone stimulates ventilation by activating progesterone receptors in the central nervous system; estradiol may facilitate progesterone's actions by increasing progesterone receptors. This study evaluated whether progesterone and estradiol contribute(More)
BACKGROUND Clinical experience with cidofovir in pediatric solid organ transplantation is limited. We assessed the effect of cidofovir use on renal function in pediatric solid organ transplant recipients. METHODS Wilcoxon signed-rank tests were used to determine if changes in renal function were significant, Wilcoxon rank-sum tests to test the association(More)
