evaluation of under vision total tubeless pcnl as a novel technique in comparison to total tubeless pcnl

Introduction: this study aims to evaluate under vision total tubeless pcnl (tt-pcnl) as a novel technique in reducing surgeon exposure to x-rays compared to the standard total tubeless pcnl. percutaneous nephrolithotomy (pcnl) has been widely welcomed as a less-invasive medication for kidney stones. however, because it is usually performed using fluoroscopy, the endourologist is at risk of chronic x-ray exposure.methods: the number of 76 consecutive patients who were candidates for pcnl surgery was randomized into two groups: 38 patients experienced tt-pcnl, and 38 patients underwent under vision tt-pcnl. the results were compared with fluoroscopy time and surgeon satisfaction.results: the fluoroscopy time in the under vision tt-pcnl group was lower than in the total tubeless pcnl group (0.02). surgeon satisfaction was higher in the under vision total tubeless pcnl group than in the tt-pcnl group (p-value=0.001). the mean total duration of surgery in the tt-pcnl under the vision group was lower than the total tubeless pcnl group (p-value=0.04). there was no significant difference between the two groups’ complications.conclusion: the under vision tt-pcnl is compared to the normal pcnl in safety and effectiveness, but also it can significantly reduce the use of a fluoroscope. moreover, surgeon satisfaction is better compared to the standard technique.
