Every week the Editor-in-Chief selects the Article of the Week from the current issue of BJUI. The abstract is reproduced below and you can click on the button to read the full article, which is freely available to all readers for at least 30 days from the time of this post.
In addition to the article itself, there is an accompanying editorial written by a prominent member of the urological community. This blog is intended to provoke comment and discussion and we invite you to use the comment tools at the bottom of each post to join the conversation.
Finally, the third post under the Article of the Week heading on the homepage will consist of additional material or media. This week we feature a video from Dr. Barnes and colleagues summarising their paper on stent extraction strings.
If you only have time to read one article this week, it should be this one
Do ureteric stent extraction strings affect stent-related quality of life or complications after ureteroscopy for urolithiasis: a prospective randomised control trial

• To determine whether ureteric stent extraction strings affect stent-related quality of life (QoL) or increase complications after ureteroscopy (URS) for stone disease.
PATIENTS AND METHODS
• In all, 68 patients undergoing URS (October 2011 to May 2013) for stone disease were randomised to receive a ureteric stent with or without an extraction string.
• Patients completed the Ureteric Stent Symptom Questionnaire (USSQ) on postoperative days 1 and 6, and 6 weeks after stent removal.
• Pain was assessed at stent removal.
• Adverse events, including early stent removal, stent migration, retained stent, urinary tract infection (UTI), emergency room (ER) visits and postoperative phone calls were monitored.
• There was no difference in stent-related QoL as measured by the USSQ between those with and without a stent extraction string, pain at stent removal between those who pulled their stent independently vs those who underwent cystoscopy for stent removal, or in the rate of UTIs, ER visits or phone calls between groups.
• Five patients (four female, one male) removed their stent early by inadvertently pulling the string; none required replacement.
• Patients without a string had a significantly longer period with the postoperative ureteric stent (10.6 vs 6.3 days, P < 0.001).
• One patient without a stent string retained her ureteric stent for 6 months, which was removed by cystoscopy without incident.
• Ureteric stent extraction strings may offer several advantages without increasing stent-related urinary symptoms, complications, or postoperative morbidity.
