Purpose Emergency double-J (DJ) stenting following “uncomplicated” ureteroscopic (UURS) stone treatment is both morbid and costly. Our study aims at identifying those patients who are more likely to require such an extra procedure. Handling of this complication will also be highlighted. Materials and Methods 319 cases of UURS cases were selected out of 903 patients, who were admitted for URS stone treatment at King Abdullah University Hospital during the period from May, 2003 to December, 2010. Thirty-eight of them (11.9%) had emergency post-URS DJ stenting within 24 hours of discharge. The medical records of all UURS cases were retrospectively reviewed. Comparison in demographic and stone-related variables was made using 2-paired t-test with P < 0.05. Operative findings of 38 stented patients were outlined. Results Significant risk factors for emergency stenting were noted in males with larger (>1.5 cm) and proximal stones (38 stented vs. 281 unstented). Operative risk factors among the 38 patients were: initial procedure time > 45 minutes (42.1%), ureteral wall edema (21.1%), repeated access for stones > 1.5 cm (21.1%), impacted stone (10.5%) and ignored or missed stones/fragments (4.6%). Conclusions The need for emergency DJ stenting following UURS stone treatment is not uncommon. The routine insertion is impractical and weakly-supported. With risk-factor stratification, selective and individualized DJ stenting policy is recommended.
