Introduction: The surgical treatment of paraphimosis can have a high failure rate, particularly where changes are chronic. The aim of this retrospective study is to describe the use of a Y-V plasty for the treatment of paraphimosis in dogs.

Materials and Methods: Data retrieved from medical records included signalment, clinical history, length of exposed penis, surgical technique and outcome. Surgical techniques included preputial advancement with cranially site Y-V plasty (Y-VPA), or a Y-V plasty combined with a cranial transposition of the elevated penile sheath (MCTPS).

Results: Seven dogs were included. Median age at the time of presentation and median duration of paraphimosis were 4.7 years (from 4 months to 12 years) and 635 days (4 to 1460), respectively. Mean size of preputial shortening was 2.3 centimeters (1.5 to 3.5). Y-VPA was performed in all patients and MCTPS was additionally used in 2 cases. Follow-up was available in 6 dogs with a mean of 33 months (2 to 111). Only a minor penile protrusion of few millimeters was observed in one patient treated by Y-VPA and MCTPS. Revision surgery was not necessary in this patient.

Discussion/Conclusion: Correction of paraphimosis in dogs was possible with Y-VPA with or without MCTPS. The results of this series appear to be better than those previously published for the surgical treatment of chronic and idiopathic paraphimosis.
