Complications Of Forgotten Ureteric Stents - Our Experience In A South Indian Tertiary Urology Centre

Background: Use of ureteric stents is accepted standard practice in the management of ureteric obstruction. Forgotten ureteric stents results in significant morbidity and financial loss to the patients. The aim of our study is to evaluate the incidence of various complications in these cases and different techniques adopted in their management. We also studied other factors such as duration of stent insitu, literacy level of the patient and socioeconomic status. Methods: Thirty eight patients presented with forgotten ureteric stents to urology department between August 2009 and January 2012 was included in the study. Results: Mean age of patients was 41.3 years. Seventy nine percent of patients have the stent for less than 5 years. Seventy four percent of patients in the cohort were uneducated and 82% were from poor socioeconomic background. Ninety percent of cases were unilateral cases. Most common indications for stent placement were following percutaneous nephrolithotomy and ureteroscopic lithotripsy for stone disease. Forty seven percent of patients were presented with dysuria and urinary frequency. Seventy four percent of patients were presented with normal creatinine levels. Thirty nine percent of patients were found to have encrustations at more than one site. Majority of stones were composed of calcium oxalate and calcium phosphate. Conclusion: This study emphasises the importance of regular follow up, maintenance of stent register, patient education and prompt removal of stent to avoid potential complications.
