URETER, STERILE, UTI
All patients underwent preoperative clinical examination. Imaging included abdominopelvic ultrasound, KUB radiograph, and computed tomography without contrast. Laboratory studies included urinalysis and urine culture to exclude preoperative UTI. Following informed consent, a selective urine sample was obtained intraoperatively from the ureter using the ureteroscope before polyurethane JJ stent insertion. The urine sample was analyzed to exclude UTI and urine culture done.Two weeks after stent insertion, urinalysis was performed for all patients and a urine culture was performed pre stent removal.The stent was removed 2 weeks after insertion under aseptic conditions in the operating theater via cystoscope. A segment of the stent, about 3–5 cm from the bladder segment of the stent was placed in a sterile cup and sent to the laboratory for culture (Table Indications for ureteral stent insertion
