  • Title: [New development of a one-way-system for percutaneous nephrostomy (author's transl)].
    Author: Harzmann R, Haacke C, Bichler KH.
    Journal: Urologe A; 1981 Jan; 20(1):63-7. PubMed ID: 7194534.
    Abstract:
    Since a surgical nephrostomy is not satisfying as either a temporary or permanent means of urinary diversion and puts a heavy burden on the patient as well, the percutaneous nephrostomy is gaining significance. Broad application of ultrasonically or radiologically controlled punctures of the renal pelvis have been til now limited due to the lack of a one-time system which is easy to manipulate. A new puncture system was thus developed with which a percutaneous nephrostomy can be performed with an up to 14 FU catheter drainage in a taechnically simple fashion. Use with a total of 41 punctures proved to be unproblematic. In three cases the puncture was unsuccessful. One case of post puncture bleeding made a surgical revision necessary. The drainage system was well tolerated. The polyurethane fistel catheter was checked at six-week intervals and showed only a few shell-shaped incrustations identified by scanning electron microscopy. Any loss of function of the fistel catheter caused by these incrustations was not observed. Catheter change, which is necessary at regular intervals, was possible in all cases without difficulties.
