No change in complication rate using spring-loaded gun compared to traditional percutaneous renal allograft biopsy techniques.

The previous methods to biopsy renal allografts at our institution involved the use of the Franklin-Silverman or Tru-Cut needles. Unfortunately they had a significant rate of post biopsy bleeding secondary to deep penetration when excess force was used to penetrate a tough transplant capsule. Although spring loaded biopsy devices have been widely used for native kidney biopsies over the past three years, the complication rate for renal allograft biopsies has not been sufficiently evaluated.

Late withdrawal of cyclosporine in stable renal transplant recipients.

The use of cyclosporine (CsA) in renal transplantation has been associated with an improvement in 1-year graft survival, but has not changed the rate of late graft loss. We sought to determine whether the intent to withdraw CsA late after renal transplantation affects renal transplant survival and whether there is a racial difference in the effect of CsA withdrawal. This retrospective study included 384 consecutive patients receiving a renal transplant during the 1984 to 1991 period who were treated with CsA/azathioprine/prednisone and who had a functioning allograft 6 months following transplantation.

Clinical and pathologic features of familial focal segmental glomerulosclerosis.

The occurrence of focal segmental glomerulosclerosis (FSGS) in a familial pattern has been rarely reported previously. Over the last 10 years we have treated 31 patients among eight families with familial FSGS. The diagnosis was confirmed by renal biopsy in 18 cases, and each family had at least two members in whom the diagnosis was confirmed histologically.

Surgical treatment of primary hyperaldosteronism.

Objective: A retrospective review of patients with primary hyperaldosteronism treated at the Duke University Medical Center was performed.

Summary Background Data: The management of patients with primary hyperaldosteronism has changed dramatically in the past 20 years. The outcome of surgical treatment was examined to optimize the management of these patients.

Coexpression of May-Hegglin anomaly and hereditary nephritis in a family.

In three generations of a family investigation for coexpression of May-Hegglin anomaly and hereditary nephritis was done by routine studies, as well as electron microscopy of renal tissue and blood cells, platelet aggregation studies, audiograms, and ophthalmologic evaluations. The propositus had typical May-Hegglin anomaly and a mild form of hereditary nephritis. One son had May-Hegglin anomaly and possible hereditary nephritis, and one daughter had May-Hegglin anomaly and probable hereditary nephritis.
