Obstructive urolithiasis is the retention of urine subsequent to lodgment of 
calculi anywhere in the urinary conduct from up to urethral orifice. The disease 
results in heavy economic losses to the livestock industry as it is attributed 
the fifth most prevalent cause of death in feedlot. Obstructive urolithiasis is 
a serious, potentially fatal condition, most commonly causing symptoms in 
castrated male animals, but also occurring in breeding males. Many surgical 
approaches and techniques for the diagnosis and the treatment of the disease 
have been described with their relative merits and demerits in the literature.
