Modified circumferential preputioplasty using a Keyes biopsy punch for treatment of type I phimosis in two kittens.

Abstract

Case series summary: Medical records of two kittens diagnosed with type I phimosis were reviewed. Clinical signs on presentation, investigations, description of the surgical technique, and short- and long-term follow-up were reported. Type I phimosis was diagnosed in both kittens based on the clinical, radiographic and surgical exploration findings. Modified circumferential preputioplasty using 4 and 6 mm Keyes biopsy punches was performed by the same surgeon in each case. The biopsy punch was centred over the existing narrowed preputial orifice and rotated clockwise and anticlockwise to obtain a sharp circumferential cut through the skin and submucosa of predictable diameter. The underlying mucosa was resected with micro curved scissors and mucocutaneous apposition was achieved with simple interrupted sutures placed circumferentially. Minor protrusion of the tip of the penis was recorded in the short-term follow-up (2 weeks) but resolved on the long-term follow-up (10 and 72 months). No evidence of urinary tract infection, strictures or clinical signs associated with phimosis were recorded at long-term follow-up.

Relevance and novel information: This short case series describes the surgical correction of type I phimosis by circumferential preputioplasty implemented using a Keyes biopsy punch in two kittens. The technique described in this case series can be considered alongside other reported surgical techniques, and appears to provide a reliable, rapid and accurate removal of preputial skin in the two reported cases.
