[Repeat kidney transplantation].

Background: The objective of the study was an analysis of results of repeated kidney transplantations (Tx2, Tx3) implemented during the first 29 years of activities of the Transplantation Centre of the Institute of the Clinical and Experimental Medicine in subjects with a different maintenance immunosuppression.

Methods And Results: The retrospective study pertains to 134 Tx2 and 17 Tx3 in 134 non-diabetic subjects: 43 of them had during Tx1 and Tx2 (1966-1981 and 1966-1985 resp.) immunosuppression on the basis of azathioprin (Aza, sub-group AA), 42 during Tx1 (1972-85), Aza, while during Tx2 (1984-85) immunosuppression on the basis of cyclosporin (CyA, subgroup AC) and 49 both during Tx1 and Tx2 (1985-93 and 1986-95 resp.

[Dynamic bone scintigraphy in the diagnosis of renal osteopathy].

Unlabelled: A study was undertaken to assess types of RO by a dynamic modification of osteoscintigraphy 53 pts dialyzed for 27-75 mths, 19-52 yrs old were divided, according to histological bone pictures, into 4 groups: I) 11 pts with hyperparathyroidism, II) 12 pts with osteomalacia, III) 11 pts with mixed RO, IV) 11 pts were after parathyroidectomy (PTE) and 13 controls.

Investigations: the rate of 99mTc-Sn-HEDP accumulation in the skeleton, skeletal/background radioactivity index both registered for 60 min. (parameters K and P), serum levels of C-PTH, bone isoenzyme of alkaline phosphatase (bALP), acid phosphatase (ACP), free hydroxyproline (S-Hypro).

[Hyperparathyroidism and parathyroidectomy in dialyzed patients].

The authors present older and more recent views regarding the pathogenesis of hypocalcaemia and secondary hyperparathyroidism in patients with chronic renal failure with emphasis on the impact of inorganic phosphate retention and lack of 1,25-dihydroxyvitamin D3 in body fluids. As regards therapeutic procedures the initial problem is to control hyperphosphataemia and to suppress the increased parathormone secretion in particular in dialyzed patients. When treating hyperphosphataemia it is necessary with regard to the severity of the finding to use concurrently several procedures and avoid aluminium phosphate binders.

The optimal treatment of lymphoceles following renal transplantation.

Lymphoceles are well-recognized complications following kidney transplantation. The authors describe their experience with the treatment of eight clinically significant lymphoceles (incidence 2.7%).
