Abstract

The aim of this study was to evaluate the necessity for stenting after ureteroscopic lithotripsy We performed a systematic research of Medline Embase Cochrane central registration for RCTs concerning the comparison between stented and nonstented postureteroscopic procedures for stone removal and reference lists of the included study were also screened 15 trials were included and data related was extracted and analyzed in meta way No difference was detected in stone free rate and stricture formation between the two groups P = 069 P = 067 Participants with stents had higher risk of being infected than those without RR = 172 but with no difference Stent related lower urinary symptoms were more frequently experienced by stented patients dysuria RR = 524 P = 0003 hematuria RR = 728 P = 0001 loin voiding pain RR = 524 P = 0003 Postoperative pain score were also higher in patients with stent in the early period after surgery with mean difference 095 P = 0002 With additional time needed for the placement of stent the operative time in stented patients were 336 min longer than those without stenting P = 002 The additional cost for longer operative room stay together with the sent and cystoscopic stent removed conditionally and made the cost for stented patients much higher No difference were detected in length of hospital stay between both groups P = 022 the stented patients were even of lower rate pay unplanned hospital visit RR = 081 P = 055 Stenting did not improve the outcome of patients who underwent ureteroscopic lithotripsy but associated with increased complication rate Routinely stenting after ureteroscopic procedure for stone removal was not necessary however it still should be reserved conditionally
