- Abstract
Purpose: Latest publications state equal efficacy of a recently introduced new percutaneous technique ('ultra-mini PCNL', UMP) and flexible ureteroscopy (fURS) in the treatment of medium-size urinary stones. Today we face challenges concerning cost-effectiveness and reduction of in-hospital length of stay. In this retrospective study, we compare clinical outcome parameters and costs of treatment (endoscopes and disposables) of both techniques. Methods: Thirty patients treated by UMP at two tertiary university centres were matched to 30 fURS patients from previously recorded databases. Data analysis included operating time, length of stay, stone-free rates (SFR), complications (>Clavien II), ancillary procedures (presurgical ureteral stenting, secondary ureteral stenting or placement of a nephrostomy tube, secondary procedures) and costs for disposable materials and instruments (endoscopes, as calculated per procedure). Results: We found no significant differences in operating times (UMP vs. fURS: 121/102 min), hospital length of stay (2.3/2.0 days), SFR (84/87 %) and complications (7/7 %). Costs for disposable materials and endoscopes were 656 euro (UMP) and 1,160 euro (fURS) per procedure. Conclusions: UMP and fURS are both safe and effective in the treatment of medium-size urinary stones. Costs for endoscopes and disposable materials are significantly lower in UMP.
