SCOTTSDALE, AZ USA (UroToday.com) - This was the second of two posters that addressed the poor yield of invasive and expensive urologic testing in patients with recurrent UTIs. Despite the fact that current guidelines are lacking, it is common clinical practice to perform cystoscopy and various imaging in women with recurrent UTIs.
The objective of this study was to determine the yield of upper tract imaging in detecting abnormalities in women with documented rUTIs. It was a prospective database review of non-neurogenic women with documented rUTIs who underwent upper tract imaging (renal ultrasound (US), CT scan, or IVP). Results were on 170 of 280 women with rUTIs, including US alone (N=76), CT alone (N=47), US and CT (N=38), and IVP with US or CT (N=9). Out of total imaging findings (N=84 in 76 women), 81/84 (96.4%) were noncontributory: duplicated systems (10), non-obstructing renal stone (16), renal cyst (46), renal tumor (1), questionable small renal lesion (8). In 3/76 women (3.6%), mild unilateral hydronephrosis appeared related to rUTI; but no clinical parameters (e.g., immunosuppression, history of urethral dilation or kidney stones, degree of cystocele, post-void residual) were correlated with these upper tract findings. Six of 15 (40%) patients with kidney stone history had stones on imaging (ranging from1–3 mm) vs 10/155 (6.5%) of patients who did not have such history had stones on imaging (p < 0.0001).
The authors concluded that in this cohort of predominantly Caucasian postmenopausal women, upper tract imaging yielded a low percentage of significant findings associated with rUTIs.
