text: Ureteral stents and urethral catheters are employed to facilitate urine flow and drainage from the upper and lower urinary tracts, respectively.1 Ureteral stents, which have become a cornerstone of contemporary urological practice, are indicated for the prevention or relief of ureteral obstruction and facilitate the flow of urine from the kidney to the bladder.1–4 Typical indications for stent placement include obstructing ureteral calculi, ureteral strictures, carcinomas, retroperitoneal fibrosis, trauma, congenital anomalies, obstructive uropathy and facilitation of reconstructive surgery and transplantation.2,5 Indwelling urethral catheters are utilized in the management of an array of both chronic and acute conditions, generally indicated where mobility is compromised and/or there is damage to the physiology of the bladder or urethra.
