title: Ureteric stenting after ureteroscopy for ureteric stones: a prospective randomized study assessing symptoms and complications.
abstract: OBJECTIVE
  To compare patients with and with no stenting after ureteroscopy for ureteric calculi, as placing such stents is routine, although many patients complain of pain and urinary symptoms.
  
  
  METHODS
  In all, 45 patients with ureteric calculi amenable to ureteroscopic management were prospectively randomized into a stented (23) or an unstented (22) group. Standard ureteroscopic basketing and lithotripsy was used, through a ureteroscope (8.5 F) with or without ureteric dilatation. Symptom questionnaires were completed by the patients after treatment, and they were followed radiographically to assess stone-free rate and evidence of obstruction.
  
  
  RESULTS
  There was no statistically significant difference in age, stone size, operative duration or hospital stay between the groups (P > 0.05). Furthermore, there was no statistical difference in flank pain or urinary symptoms (P > 0.05), except haematuria, between the groups; haematuria was more severe and prolonged in the stented group (P = 0.001).
  
  
  CONCLUSIONS
  Uncomplicated ureteroscopy for removing calculi is safe with no stent after treatment, and after considering complications and side-effects we think that the routine use of ureteric stents after uncomplicated ureteroscopy for stone extraction is unnecessary.
