Routine placement of ureteral stents is unnecessary after ureteroscopy for urinary calculi

摘要: Objectives. To report a matched comparison of patients with and without stenting after ureteroscopy for calculi, including middle or proximal ureteral renal calculi. The elimination routine would prevent stent pain, minimize the need re-instrumentation, reduce costs—as long as efficacy safety are not diminished. Methods. Of 318 who underwent ureteroscopy, 81 (25%) did have placed. those, 51 were suitable analysis included distal (n = 22), 11), calculi 18). This cohort was to stented group by stone size location. Results. preoperative characteristics groups similar. A stone-free rate 86% 94% achieved in nonstented groups, respectively (P 0.32). Complications less frequent (flank pain 3 postoperative nausea 1) than (hospital visits flank 12, persistent vomiting 1, sepsis perinephric hematoma urinary retention (total 4 versus 16, P 0.025). Conclusions. Ureteroscopy stones placement has been previously described. Our experience expands include (22%) (35%) data suggest that ureteroscopies short operative times minimal trauma, stents may be necessary, even if performed.
