Association Between Ureteral Double J Stent Colonization and Lower Urinary Tract Symptom Severity: A Cross-Sectional Study.

Introduction Double J stents (DJS) are commonly used in urological practice, but they do have a risk of complications, such as infection and hematuria. This study explored the association between ureteral double J stent colonization and lower urinary tract symptom (LUTS) severity. Methodology This cross-sectional study was conducted from January 2021 to June 2021 in patients admitted to a tertiary care hospital in Karachi, Pakistan, who required double J stent (DJS) insertion. Patients who came to the site for stent removal were invited to participate in the study and enrolled using a consecutive sampling technique between January 15, 2021, and March 15, 2021. Results The study enrolled 176 patients, of whom 73.33% had colonization and the remaining had no colonization. The factors significantly associated with symptom severity included colonization of the DJS (P-value = 0.001) and the patients' ages (P-value = 0.046). The two groups have significantly different symptoms, which included incontinence (P-value = 0.001), polyuria (P-value = 0.001), and nocturia (P-value = 0.001). Conclusion Our study found more severe symptoms in DJS patients with colonization than in those without colonization. Irritative voiding symptoms, including nocturia and dysuria, are more common in DJS patients with colonization.
