A simple procedure for relieving obstruction of sump catheters.

A simple technique for the desobstruction of sump drains is described. The technique consists of disassembling the obstructed catheter, leaving the outer part in situ and cleaning the disengaged inner and outer parts. Proper function is regained after reassembly of the catheter. The procedure is indicated when exchange of the sump catheter is impossible due to an immature catheter tract.
