[Ultrasonically-guided percutaneous nephrostomy].
Ultrasonically-guided percutaneous nephrostomy using Seldinger's technique is the most accurate and reliable procedure for pelvic catheterisation in obstruction-induced hydronephrosis. The procedure is straightforward and independent of renal function. Post-renal uraemia may thus be measured and corrected; hydropyonephrosis drained prior to surgical operation of choice. Injection of contrast media may identify an anatomo-pathological situation which cannot be defined with i.v. or retrograde pyelography.
