LUTS-Normal Stent VS Carbothene Stent in a Health Center- Retrospective and Prospective Study

Background: Ureteral stent removal is associated with some post operative symptoms such as changes in the frequency of urine,frequent nocturia, occasional episodes of blood stained urine,pain in the suprapubic region which occurs due to the material composition and the dimensions of the stent as well. Polyurethane stent are regularly used in the operation theatres but in the recent years carbothane stent has showed some efficacy and hence necessitates a comparison.

Objectives: To study the prevalence of symptoms of lower urinary tract symptoms in patients with polyurethane stent and carbothane stents

Materials and Methodology: A prospective study was conducted among patients who had their stent removed to the Department of Urology in a tertiary health care hospital from January 2021 to April 2021. A simple random sampling technique was employed and 40 patients were identified for the study. The relationship between the different stents and the onset of symptoms

Results: It is seen that the onset of lower urinary tract symptoms had an equal incidence among the two genders hence the presence of symptoms plays a crucial role in distinguishing the efficacy of the stents. Here in this study only 5% of carbothane stent patients had changes in frequency of micturition where as 65% polyurethane stent patients reported change frequency similarly 60% of polyurethane stent patients had changes in Frequency of nocturia whereas same was reported in 20% of the patients. Loss of urine before reaching the toilet was the primary complaint in 30 % of polyurethane stent patients but only 2% of carbothane stent patients occasionally had this complaint. Apparently the stream of urine was occasionally continuous in 70% of polyurethane stent patients but was always continuous in 85% of carbothane stent patients. A sense of incomplete evacuation was experienced by 40% of polyurethane stent patients but only 1% of carbothane stent patients had such complications Similarly pain in the suprapubic region, straining oneself while micturition and presence of hematuria was experienced by a greater percentage of polyurethane stent patients than that of carbothane stent patients.

Conclusion: It is seen that carbothane stent have a better patient compliance and a low onset of lower urinary tract symptoms when compared to the normal polyurethane stent and hence medical management of the symptoms was required in the postoperative period
