Patients were informed in detail of the possible risks and advantages of the 2 procedures (placement of a segment of a
Nelaton catheter as a stent in CBD or T-tube drainage).
After the first voiding, a
Nelaton catheter was passed into the bladder through the urethra, and then, the volume of urine collected was measured by using a graduated cylinder.
The patient was catheterised immediately with a 16F
nelaton catheter and 3 000 mL clear urine was drained.
(1) In 1984, Auguste Nelaton invented the first vulcanized rubber catheter for urethral dilatation, now known as the
Nelaton catheter. (1) Maisonneuve (1854) and Otis (1872) developed the urethrotome to cut the strictured part of the urethra.
In intervention group, patients controlled for ability to void every 4 hours after surgery and if the patient could not void,
Nelaton catheter used every 4 hours upto 2 times.
