Preferred Abstract (Original): 

Randomized trials support stent omission after ureteroscopy in select cases, though generalizeability isUnclear and criteria for stenless ureterorenoscopy are unknown. In this study we evaluate the postoperative clinical Symptoms in patients who undergo balloon dilation of ureter orifice prior to ureteroscopic stone therapy without stenting.  The study cohort consisted of 35 patients (23 males, 12 females) with mean age of 46.63 years (range: 16-74) who hadUndergone ureteroscopic intervention due ureteral stone between November 2006 and October 2007. The average stonediameter was 7.6 mm (range: 5-15). The stones were located in lower, middle and upper parts of the ureter in 30 (85.71%), 3(8.57%) and 2 patients (5.71%) respectively. Intra-operative ureter orifice balloon dilation was routinely done for allPatients before insertion of semirigid ureteroscope (7.5/12Fr). All patients were assessed during the first 7 days following the operation for colicky pain, lower urinary tract symptoms, stone free rate and requirement for intramuscular or/and intravenous analgesics. Thirty three patients (94.28%) did not need any additional analgesics (pain scale < 2). Only twoPatients (5.71%) were in need of intramuscular or/and intarvenous analgesics (pain scale > 5). Three patients sufferedfrom moderated coliky pain but they did not need another form of analgesics (pain scale < 4). All patients became free ofStone by the end of the first week after the operation. Balloon dilation of ureter orifice before ureteroscopic intervention isharmless step. It is not an indication for stenting in uncomplicated successful ureteroscopic ureteral calculi management.
