[Urological complications following ovariohysterectomy in dogs (author's transl)].

Of the total number of dogs submitted with complications following ovariohysterectomy (109), eighteen were found to show pathological changes of the kidney and/or excretory urinary ducts. Eleven patients showed specific urological problems such as pollakiuria (7 cases), urinary incontinence (6 cases) and haematuria (5 cases). When there was a reason for doing so, specific urological studies were undertaken, including excretion urography in seven cases, in addition to physical and laboratory studies. During laparotomy and/or post-mortem examination (the latter being carried out in eight dogs), the following adhesions were observed, among others: the cervix stump adhered to the bladder in nine cases, to the right ureter in five and to the left ureter in three cases. Either granulomas at the ovarian stump (one case) or cervix stump (five cases) or actual ligation of the ureters in the ovarian (two cases) or cervix stump ligature (three cases) caused partial or total obstruction, which occasionally resulted in hydro-, pyo- or haemonephrosis, atrophy of the kidney or focal nephritis.
