Abstract
Twelve clinical cases of chronic obstructive urolithiasis in male goats
presented to University Veterinary Hospitals of Kerala Veterinary and Animal
Sciences University at Kokkalai and Mannuthy during a period of twelve months
from March 2019 to March 2020 were selected for the study . The study was
undertaken with the objective to comparatively evaluate two surgical techniques -
modified proximal perineal urethrostomy (MPPU) and tube cystostomy for the
surgical management. The occurrence of obstructive urolithiasis was found to be
more in nondescript goats of three to seven months age group from November to
January. Diagnosis of the condition was done by clinical examination,
hematological and serum-biochemical parameters, radiographic and
ultrasonography evaluation. Ultrasonography proved to be an effective diagnostic
tool for assessment of urinary bladder and detection of uroliths. A significant
difference between haematological and biochemical parameters was observed on
day 0 and day 14 within groups. A direct access to proximal perineal urethra
provided quick relief and the technique was found effective in managing chronic
caprine obstructive urolithiasis with intact urinary bladder. Tube cystostomy
provided direct visual assessment of urinary bladder, precise fixing of Foley’s
catheter and retrieval of uroliths. The MPPU technique demanded high levels of
skill and accuracy to locate the perineal urethra. Tube cystostomy technique was
found to be more invasive, it was identified as an effective approach for correcting
cystorrhexis resulted form obstructive urolithiasis. Functional patency of normal
urethra was regained in five out of six animals of each group by third post-operative
week. Urinalysis revealed alkaline urine in all animals, hematuria in seven animals,
proteinuria in six animals and relatively higher specific gravity on the day of
presentation which returned to normal on 14th post-operative day in nine animals.
Microscopic examination of urine sediments revealed the presence of erythrocytes,
struvite crystals and epithelial cells. Analysis of the retrieved calculi using FTIRATR confirmed bandwidths of the infrared wavelength identical to the standard
wavelength of magnesium ammonium phosphate.
