LEARNING OBJECTIVES: 
1.	To describe the etiopathogenesis, clinical presentation and imaging manifestations of infections affecting the lower genitourinary tract. 
2.	To discuss the clinical implications of specific imaging findings.
3.	To discuss the role of image-guided interventions and pertinent management issues. 

BACKGROUND:
Lower genitourinary infections range from more commonly encountered cystitis to relatively uncommon mycobacterial infections such as TB, fungal infections such as candidiasis and parasitic infections such as schistosomiasis etc. These infections may be suspected clinically or come as a surprise on imaging. Cross-sectional imaging techniques, particularly CT enables accurate detection of these infections. 

CONCLUSION:
A wide spectrum of lower genitourinary infections are encountered in the clinical practice of which some are relatively uncommon and may pose a challenge for the unwary radiologist. Knowledge of salient imaging features of these infections is of utmost importance because prompt recognition enables appropriate management.
