This case series describes five female dogs with congenital ectopic ureter presenting with delayed-onset urinary incontinence out of 22 female dogs diagnosed with ectopic ureter over a 102-month period at a veterinary teaching hospital. All five dogs improved following surgical treatment of ectopic ureter, but only three remained continent long-term without further intervention. Delayed-onset urinary incontinence in female dogs with ectopic ureters may be more common than the current literature suggests. Congenital ectopic ureter should be considered and investigated as a possible contributing factor in female dogs presenting with delayed-onset urinary incontinence.
BACKGROUND The surgical management of epiphora due to Primary Acquired Nasolacrimal Duct Obstruction (PANDO) is Dacryocystorhinostomy (DCR). Endonasal DCR is becoming more popular than external DCR because of many advantages like avoidance of facial scar, reduced morbidity, lesser time consumption and ease of revision surgery. The aim of the study is to find out the success rate, complications, advantages and disadvantages of endoscopic DCR with and without silastic tube insertion. MATERIALS AND METHODS We performed a clinical prospective comparative study of 70 patients with diagnosis of epiphora due to PANDO in the ENT and Ophthalmology Department of Government Medical College Hospital, Thrissur, from July 2008 to July 2014. Selection of type of operation was left to the patient's choice. A total of 50 patients were enrolled in the Endo DCR group and 20 patients were enrolled in the silastic tube insertion group. RESULTS All the 20 patients who were subjected to Endo DCR with silastic tube achieved anatomical and functional success (100%). In the Endo DCR without silastic tube group, 42 out of 50 patients (84%) achieved anatomical and functional success. CONCLUSION With the introduction of silastic tube, the success rate has increased. It is more useful in patients with less compliance and previous failures.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
