THE ROLE OF URETERAL STENTS IN NON-COMPLICATED RETROGRADE URETEROSCOPIES FOR URETERAL CALCULI
Abstract:
The study objective is to evaluate the benefits of inserting the ureteral stent, for one week, in
patients whose ureteral calculi were endoscopically fragmented without intra-operatory complications.
Material and method. The study comprised 140 patients who had ureteroscopies with the ultrasonic
fragmentation of ureteral regional anaesthesia, the calculi size being between 5-10 mm. 109 patients,
who had intra-operatory incidents, were split into two groups: A – 54 patients – to whom a stent was
inserted intra-operatory, and B – 55 patients – without stent insertion. The following parameters were
observed: the presence of lumbar pain, suprapubic pain, renal cramps, irritative urinary syndrome,
urinary infection and the need for analgesic administration comparatively for the two groups. Results.
The presence of the post-operatory ureteral stent diminishes the lumbar, suprapubic and colicative
pains, reducing the need to administer analgesics, but it increases the risc of urinary infection and of the
irritative urinary syndrome. Conclusions. The ureteral stent inserted at the end of the endoscopic
interventions of ureteral calculi fragmentation has a role in the favourable evolution of patients by
increasing the post-operation comfort, but it is also inconvenient to extract it after a week.
