Therapeutic process
URETER, EMERGENCY
A mid-stream urine culture (MUC) and a blood culture were performed after hospitalization, and empiric antibiotic therapy (cephalosporin) was administered because In the PCN group, patients were placed into the prone position, and the renal puncture point was located using ultrasound. Under local anaesthesia, the nephrostomy catheters (8 Fr) was inserted under ultrasound guidance and drainage fluid was obtained for bacterial culture. Emergency ultrasound or CT was performed to check whether drainage was restored. If failed, the patients were switched to the RUS group in time.In the RUSI group, patients were placed into the lithotomy position. Urethral surface anaesthesia was performed, and a zebra guidewire was inserted into the ureter on the affected side using a cystoscope. A F5 DJ tube was inserted and guided by a guidewire. Then, we conducted catheterization for all the DJ patients and a urine sample was taken from the catheterization during DJ stent insertion. An emergency ultrasound or CT was performed to check whether drainage was restored. If failed, the patients were switched to the PCN group in time.
