APPLICATIONS AND COMPLICATIONS OF POLYURETHANE STENTING IN UROLOGY
Abstract
Background: As surgeons working in a developing country, we decided to review our experiencewith polyurethane stents instead of the more expensive ones on common urological procedures
and analyzing our experience with respect to their usefulness versus their problems and outcome.
Methods: This stusy was carried out at Armed Forces Institute of Urology, Rawalpindi and
Combined Military Hospital, Kharian Cantonment, Pakistan through March 2002 through May
2004. During this period 342 of patients were operated requiring stent and 220 patients out of
these had polyurethane as stent material for different urological operations. Results: Among the
220 patients who underwent polyurethane stenting, early complications included fever, infection,
voiding symptoms while stent migration, encrustation and stent stiffness was encountered as later
complications. Conclusion: The benefits of Polyurethane stents are its strength, versatility and
low cost. Poor biodurability and biocompatibility only limit its use; these are reasonably effective
in our setup but should only be used for short duration.
Key words: Urology Stents, Polyurethane, Complications.
