Surgical treatment of hypospadias. Techniques and results in six dogs

100%

Galanty M. , Jurka P. , Zielinska P.

nr 3

235-243

Various types of hypospadias and methods of surgical treatment of this anomaly in 6 dogs was described in this article. Methods of surgical treatment were set up individually for each case and depended on the type of hypospadias and coexisting anomalies. Shortening of the penis was performed in two dogs, amputation in three cases and an urethral reconstruction in one patient. Castration was performed in three cases. Persistent frenulum of the prepuce was found in two dogs. Additionally three patients were submitted to the plastic surgery of the prepuce anomalies. In one dog, the loose and free falling part of the prepuce was suspended and attached to the abdominal integument according to the original own method. In all dogs, uncomplicated wound healing was observed. Surgical procedures resulted in improved cosmesis with reducing clinical signs of hypospadias and other coexistent anomalies.

The absence of sexual dimorphism in Pyrenean desman Galemys pyrenaicus (E. Geoffroy, 1811) makes it difficult to sex live animals. This paper presents a method of sexing desmans observing their external genitals. Based in a sampling of 49 animals from the north of Spain, it was possible to identify the penis of males, independently of the age or season.

We made a comparative anatomical study of entobdelline monogenean skin parasites from the blotched fantail ray, Taeniura meyeni (= T. melanospila) from public aquaria and fish-holding facilities distributed widely across the western Pacific Ocean. These facilities were located in Australia (Mooloolaba, southern Queensland; Cairns, northern Queensland), Taiwan and Japan. The capture localities of the aquarium fishes are unknown to us, with the exception of the individual fish from northern Queensland which came from Sudbury Reef, a local inshore reef. Entobdellines from southern Queensland differed morphologically from those from northern Queensland and Taiwan and the 2 new monogenean species are described and named Neoentobdella garneri sp. nov. and N. taiwanensis sp. nov., respectively. We determined that an entobdelline collected by Dyer and co-workers from a ray identified as T. melanospila (= T. meyeni) from an aquarium in Okinawa, Japan and identified by them as Entobdella squamula (Heath, 1902) Johnston, 1929 was misidentified and is tentatively assigned to N. taiwanensis sp. nov. The male copulatory organ of each new species resembles a penis, but evidence that these organs are eversible like a cirrus is presented. Caution is advised in deciding whether the male copulatory organs of capsalids may function as a penis or as a cirrus and we suggest that possession of a penis versus a cirrus may not necessarily indicate wide evolutionary divergence. In N. garneri, spermatophores consist of a sausage-shaped capsule and a long hollow stalk. A spermatophore received from a donor is anchored in the vagina by means of the stalk, with the capsule protruding outside the body.
