Determinants of Nephrostomy Tube Dislodgment After Percutaneous Nephrolithotomy

Abstract

Nephrostomy tube type did not influence nephrostomy tube dislodgment rates. As a patient's BMI increased, the likelihood of tube dislodgment increased in a directly proportionate fashion. This is possibly because of the nephrostomy tube being fixed directly to the mobile skin associated with their fat pannus. Although the nephrostomy tube type itself did not affect tube dislodgment rates, a redesigned nephrostomy tube or fixation device should take into account the above findings related to obese patients to reduce the likelihood of nephrostomy tube dislodgment.
