It was appreciated the need to install ureteral double “J” stent after endoscopic removal of ureteral stones. The study included 62 patients who were hospitalized in the Urology Clinic of the Medical University and Pharmacy “N. Testemitanu” during the years 2009 to 2010 (25 men and 37 women) aged between 30-58 years (mean 42 years). Patients were performed ureteroscopy and contact lithotripsy for ureteral stones in different areas. According to the study, patients were divided into two groups: I group - 24 patients (38.7%) who received surgery were performed with double”JJ” ureteral stent draining and 38 group II patients (61.2%) intervention was performed without draining the ureter. In all cases ureteroscopic access was successful, without the need to dilate the ureter. At the simple abdominal radiography made after two days, the absence of stones in 96.9% of patients in both groups became apparent. All patients were discharged, on average, after the 3rd day of surgery. The incidence of fever was slightly higher in patients with stents. Dysuria and terminal hematuria were present in patients of the first group. Installing ureteral double “JJ” stent is not required in uncomplicated ureterolithotripsy. Probabilities of developing symptoms associated with the presence of stent (suprapubic pain, disuria, terminal hematuria), stent placement requires only as indicated probes profile autostatic ,,JJ’’stents.
