This novel technique is performed using a modified stent catheter to directly access the perineal urethra through a unique site at about two to three cm below the anus and between the pin bones by gentle urethral puncture. Six cases of obstructive urolithiasis by struvite stones in goats were successfully managed by this technique and full functional regaining of urethra was achieved by third post- operative week without any complication. This article puts on record, the first- time documentation of a unique direct guided catheterisation technique which is a modification of existing MPPU procedure for early management of obstructive urolithiasis in goats.
