MANAGEMENT OF CONGENITAL URINARY OBSTRUCTION IN NEWBORN CALVES

Abstract

Congenital urinary tract obstruction is a developmental anomaly which may persist after birth in new born calves. To determine the occurrence of congenital urinary obstructionand to evaluate tube cystostomy for the management of congenital urinary obstruction inneonatal calves two studies were conducted. A retrospective study was performed toobserve the occurrence of congenital urinary obstruction in neonatal ruminants fromJanuary 2005 to November 2014. Occurrence of congenital urinary obstruction inneonatal calves was also studied in respect to age, sex, breed and season. During theperiod of 10 years, a total of 42 cases of congenital urinary obstruction were recorded,which constituted an incidence of 2.0%. In this study, maximum incidence was recordedin bovine is 38 (90%). Maximum number of cases (45%) of congenital urinaryobstruction in ruminants was recorded from March to June, July to October andNovember to February as 19 (45%), 9 (22%) and 14 (33%) respectively. Among affectedanimals, 31 were cross breed (74%) and 11 were local breed (26%). Number of affectedmales was 29 (69%) clearly ahead than affected female 13 (31%). In another study, tubecystostomy with infusion set was performed in eleven neonatal calves aged 1-6 days oldand observed for 1 month. Among 11 calves, 2 died due to severe infection andsepticemia and 2 calves needed repeated operation. Seven calves got uneventful recoveryand the cured animal showed satisfactory results. Overall successful rate was 63.6%. Theresults revealed that tube cystostomy seemed to be an effective method. In addition, thisstudy will help not only veterinarian to make them aware about the occurrence ofcongenital urinary obstruction but also to solve the problem by saving the life of neonatalcalves.
