[Antegrade pyeloureterography in the transplanted kidney].

Antegrade pyeloureterography performed via fine puncture needle yields detailed imaging of the anatomy of the renal pelvis, calices, and ureter of the transplanted kidney. It is a simple and safe examination method providing information which, as a rule, can not be obtained by urography, radioisotope gammagraphy or ultrasonography. Puncture of the collecting system of the transplanted kidney with subsequent pyeloureterography is indicated for determining the site and nature of the obstruction in the ureter in urinary stasis in the transplanted kidney, for diagnosing urinary fistulas, for functional examination of the dilated upper urinary tract, as well as for percutaneous treatment of urological complications after kidney transplantation.
