Abstract
Percutaneous interventional procedures can be valuable in the evaluation and treatment of urologic complications of renal transplantation. Patients (33) underwent percutaneous procedures, including relief of obstruction by catheter nephrostomy, diagnostic antegrade pyelography with Whitaker testing, aspiration of various fluid collections (lymphocele, hematoma, urinoma, and abscess) and renal artery angioplasty, during a 3 yr period at 3 institutions, to provide temporizing treatment and anatomic data. Surgical intervention was sometimes avoided, but more often it could be deferred to allow the patient to stabilize prior to surgery. Complications that required surgery occurred in 2 patients.
