The diagnostic utility of cystoscopy in assessing patients with persistent microscopic abnormalities of urinalysis

Abstract Background Microscopic abnormalities are common findings on routine urinalysis performed for various clinical reasons. As a small proportion of these may indicate an underlying malignancy, large number patients with referred further investigations, which includes cystoscopy. We aim to investigate the diagnostic utility cystoscopy in detecting malignancy this group patients. Methods A retrospective review who underwent standard workup microscopic (microscopic haematuria, sterile pyuria and bacteriuria) between January 2013 December 2018 was performed. Patients macroscopic concurrent UTI, recent kidney stone passage, dysmorphic red cells, proteinuria casts were excluded. Demographic information, age at diagnosis, smoking status final diagnosis extracted. Results In total, 552 identified. 58% males (319 patients). The mean 61 years 35% having history smoking. 94% pre-cystoscopy imaging. Twelve (2%) had genitourinary malignancy. Out 12 diagnosed imaging detected bladder lesion 11 (92%) Conclusions incidence persistent is low 2%. our cohort, flexible demonstrated little additional value only 1 (0.2%) by alone. Hence, we have reconsider current threshold investigating
