Objective: The objective is to assess the
benefits and adverse effects of routine ureteral stenting after uncomplicated
ureteroscopic lithotripsy. Material and Methods: Sixty patients with ureteric
calculi amenable to ureteroscopic lithotripsy were randomized to an unstented
(30 patients) or a stented (30 patients) treatment group, standard
ureteroscopic lithotripsy done using 8 French semirigid ureteroscope, and
pneumatic lithotripter used to fragment the stones. They were followed up for
postoperative flank pain, lower urinary tract symptoms (LUTS) and hematuria.
Results: There was no significant difference in the mean age (stenting 37.8
year and 33.5 year unstenting) of patients, gender and stone size in both
groups. No significant difference in the mean flank pain within 3 days
postoperative, while at day 14 postoperative flank pain for stenting group was
significant (P = 0.03). Dysuria and urgency were high for stenting group (P =
0.002 and 0.011). Hematuria within 3 and 14 days was higher in the stenting
group. Conclusion: After uncomplicated ureteroscopy, stents can be safely
omitted. Unstented patients have significantly fewer LUTS, haematuria and flank
pain.
