[Internal ureteric drainage by antegrade ureteric splinting (author's transl)]

Internal urinary drainage by antegrade ureteric splinting was successfully performed in 24 patients and the catheter left indwelling in 19. The main indications were postoperative complications leading to ureteric obstruction and urinary extravasation; this could be treated successfully by conservative means in seven out of 15 patients. Temporary splinting in three patients with fibrotic ureteric stenosis, together with dilatation by means of a balloon catheter, did not result in normal urinary flow. In four patients with urinary obstruction due to a tumour, the method became the permanent treatment. Complications of the procedure were dislodgement, obstruction and incrustation of the catheter. The procedure is an alternative to retrograde splinting and percutaneous external urinary diversion.
