Methods of ureteric stent placement and removal: experience with 200 patients

Objective To study the advantages of ureteric stents in management of ureteric obstruction, injury or surgery. Methods Ureteric stents were inserted in 200 patients by endoscopic, percutaneous or open operation approach. Local anaesthesia, sedoanalgesia and general anaesthesia was used according to requirement of the patient. Removal of the stens was also endoscopic or in complicated cases by exploration. Results Ureteric stents were placed endoscopically in 190, by open operation in 6 and percutaneous approach in 4 cases. Conclusion Ureteral stent for managing ureteral injury is a safe and simple procedure in modern urology practice. Local anaesthesia was used in 143, analgesia in 31 and general anaesthesia in 26 patients. Endoscopic removal of stents was possible in 177 cases whereas 23 patients had to undergo open surgery due to fractured or upward migrated stents. Local anaesthesia was used in 150 analgesia in 21 and general anaesthesia in 29 cases

Experience with indwelling JJ Ureteral stents

J.J stents provide free drainage from the kidney to the bladder, reduce or eliminate urine leakage and provide stenting of the ureter. They were used in a total of 200 cases. In 158 to prevent ureteric obstruction before extracorporeal shock wave lithotripsy [ESWL], in 25 to bypass obstruction and in 12 as an adjunct to complicated upper urinary tract surgery. Majority [97%] of the stents were placed endoscopically under local anaesthesia [71.5%]. In all the cases stents were successful to provide free drainage. No mortality was attributable to the use of stents but certain complications were encountered. Encrustation of the stents occurred in 21 [10.5%] and migration in 11 [5.5%] cases. Stents were removed easily under local anaesthesia by cystoscope. "J" stents thus provide an effective means to reduce complications and enhance effectiveness specially of ESWL therapy
