Clinical characteristics, classification, and surgical outcome for kittens with phimosis: 8 cases (2009–2017)

Abstract

OBJECTIVE To describe clinical characteristics and surgical outcomes for kittens with phimosis and to develop a system to classify phimosis on the basis of gross pathological lesions. ANIMALS 8 kittens with phimosis. PROCEDURES Medical record databases of 2 veterinary teaching hospitals were searched to identify records of cats ≤ 20 weeks old (ie, kittens) with phimosis that underwent surgical intervention between 2009 and 2017. For each kitten, information extracted from the record included signalment, history, clinical signs, physical examination findings, treatments, and details regarding the surgical procedure performed, postoperative complications, and outcome. RESULTS The most common clinical signs were stranguria (n = 6), marked preputial swelling (5), and a small (6) or inevident (2) preputial orifice. Six kittens had type 1 phimosis (generalized preputial swelling owing to urine pooling without penile-preputial adhesions) and underwent circumferential preputioplasty. Two kittens had type 2 phimosis (focal preputial swelling and urine pooling in the presence of penile-preputial adhesions) and underwent preputial urethrostomy. No postoperative complications were recorded for kittens that underwent preputial urethrostomy. All 6 kittens that underwent circumferential preputioplasty had some exposure of the tip of the penis immediately after surgery, which typically resolved over time. At the time of last follow-up (mean, 1.4 years after surgery), all 8 patients were able to urinate and had no signs of phimosis recurrence. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that circumferential preputioplasty and preputial urethrostomy could be used to successfully manage kittens with type 1 and type 2 phimosis, respectively.

Postioplastia circunferencial para correção de fimose congênita em gato: Relato de Caso

“…Essas anomalias incluem a presença de um pênis curto, aderências entre o prepúcio e o pênis e, estenose ou ausência do orifício prepucial (Arthur et al, 1996). No presente relato, a fimose congênita foi decorrente de uma estenose do orifício, assim como descrito em trabalho prévios (Bright & Mellanby, 2004;De Vlaming et al, 2019;May & Hauptman, 2009;Yoon & Jong, 2013). Além disso, o animal do presente estudo apresentava em seu exame clínico polaciúria, prepúcio eritematoso, devido a dermatite úmida causada pela acumulação de urina, e incapacidade de expor o pênis (características também observadas nos estudos citados anteriormente).…”

“…No presente estudo em três meses de pós-operatório o tutor do paciente não informou qualquer alteração na micção do animal, divergindo das alterações previamente descritas, de infecção do trato urinário três semanas após (May & Hauptman, 2009), e disúria sete meses após a cirurgia de correção da fimose (De Vlaming et al, 2019). Os dois trabalhos mencionados não conseguiram encontrar associação para o surgimento de disúria/infecção do trato urinário no pós-operatório dos pacientes.…”

“…Até o momento, em todos os relatos sobre correção de fimose em gatos, utilizou-se fio absorvível para suturar a mucosa da borda ipsilateral do prepúcio (Bright & Mellanby, 2004;De Vlaming et al, 2019;May & Hauptman, 2009;Yoon & Jong, 2013). O presente estudo, diferentemente, utilizou fio não absorvível para realização dessa técnica.…”

“…O tratamento de fimose é cirúrgico, com indicação da técnica de postioplastia circunferencial, caso não haja aderência entre pênis e prepúcio, e a postioplastia, seguida de urestrostomia prepucial, caso exista aderência entre prepúcio e pênis (De Vlaming, Wallace & Ellison, 2019).…”

Radiological diagnosis of phimosis in a dog and cat.

“…2 Trauma from excessive grooming of the perineum, by either the dam or littermates, is believed to be the most common cause, but it is also postulated to occur secondary to infection (UTI, balanoposthitis) and neoplasia. 1,5 Clinical signs usually include excessive licking of the prepuce, dribbling urine after urination, stranguria and preputial swelling. 1,2,3,4,5 Diagnosis has previously been limited to physical examination with an inability to extrude the penis and a visibly small preputial opening, with the exception of one study that described the use of contrast abdominal radiography in a dog with congenital stenosis of the preputial orifice.…”
