Comparative evaluation of modified proximal perineal urethrostomy with direct guided urethral catheterisation and tube cystostomy for the management of obstructive urolithiasis in male goats

Twelve clinical cases of chronic obstructive urolithiasis in male goats were selected for the study with the objective to evaluate two surgical techniques - modified proximal perineal urethrostomy (MPPU) with direct guided urethral catheterisation (Group I) and tube cystostomy (Group II) for the surgical management. Ultrasonography was effective in assessing the urinary bladder and detection of uroliths. Functional patency of normal urethra was regained in five out of six animals of each group by third post-operative week. Direct access to the perineal urethra providing quick relief to the turgid bladder was identified as the major advantage of modified proximal perineal urethrostomy technique. Tube cystostomy technique provided direct visual assessment of urinary bladder, precise fixing of Foley’s catheter and retrieval of uroliths. Even though this technique was found to be more invasive, it was identified as an effective approach for correcting cystorrhexis resulted from obstructive urolithiasis
