There is a lot of debate about whether stenting is required or not prior retrograde semirigid ureteroscopy (URS). Moreover, the effect of long-term preoperative stenting on stone-free rate (SFR) and complication rate of URS. The aim of this study was to evaluate the effect of long-term preoperative double J stenting compared with non-stenting and recent pre-stenting on the outcomes of retrograde URS. Material and methods: The data of 90 patients admitted to the Urology Clinic of the Iasi “Dr. C. I. Parhon” Hospital between January 2017 and March 2020 were collected. The patients were divided into three equal groups, matched by age, sex, stone size and location: 30 non-stented patients, 30 patients stented three months before URS, and 30 patients with stents placed for over three months before URS. SFR and the rate of main URS complications (febrile syndrome and hematuria) were in the  three groups were compared. Results: There were no statistical differences between groups in terms of SFR (73%. 77%, 80%, p = 0.6). The complication rate was similar in all three groups, for both febrile syndrome and hematuria. Conclusions: Long term preoperative double J stenting does not influence the SFR of retrograde semirigid URS. In all groups, the complication rate is very low and not influenced by preoperative stenting.
