[A new procedure for the revision and reposition of functionless peritoneal dialysis catheters].

The most important requirement for satisfactory transperitoneal dialysis is faultless functioning of the Tenckhoff catheter. Suddenly occurring functional disturbances are often caused by wrong positioning and by envelopment of the catheter by tissue, which require surgical correction. A technique for successfully locating and replacing a transperitoneal catheter by means of an operation laparoscope is described.
