Surgical management of true patent urachus in a cat

Abstract

A five-week-old kitten presented with clinical signs consistent with a patent urachus. The urachal anomaly was revealed by exploratory celiotomy and surgically excised without complications. Follow-up radiographic evaluation confirmed the complete removal of the urachal anomaly. Twenty-five months after surgery the cat remained healthy and without problems.

Ectopic cross ureter with uterus didelphys in a lamb

“…If this process is disturbed or the obliterated duct regains patency, a number of pathologies occur within this structure. Depending on the urachal part involved in the pathological process, the development of patent urachus, urachal ligament, sinus or urachal cyst and urachal diverticulum can be discerned (Laverty and Salisbury 2002;Klim et al 2006;Remedios et al 1994). Urachal diverticula develop as a result of partial obliteration and closure of the lower portion of the urachus at the bladder apex (Yu et al 2001).…”

“…Congenital and acquired diverticula are known currently (Remedios et al 1994;Scheepens and Plathenier 2005;O'Brien and Barr 2009). More frequently reported diverticula are those arising from malformation and anatomical defects, including, among others, anomalies within the urachal duct (Laverty and Salisbury 2002;O'Brien and Barr 2009). Abnormalities within the urachal duct, including the development of an urachal diverticulum, have been rarely reported in veterinary literature.…”

“…In the prenatal life, the urachus is continuous between the foetal urinary bladder and the allantois. After parturition, it undergoes atrophy at the bladder apex (Laverty and Salisbury 2002). If this process is disturbed or the obliterated duct regains patency, a number of pathologies occur within this structure.…”

Congenital Diseases of the Lower Urinary Tract

“…It is characterized by inappropriate urine loss through the umbilicus. [23][24][25][26][27] A patent urachus is often accompanied by omphalitis, ventral dermatitis, and urinary tract infections. Rarely, uroabdomen may occur when a persistent urachus terminates in the abdominal cavity.…”

Unusual urachal remnant disease in a six‐month‐old golden retriever

“…A failure of this process results in the presence of urachal remnants (Kruger and others 1995, Evans and de Lahunta 2013). These congenital abnormalities can be divided into five types: patent urachus (communication between umbilicus and bladder), urachal sinus (umbilical end is open but there is no communication with the bladder), urachal diverticulum (forms a cap on the dome of the bladder), urachal cyst (central part of the tract is patent and fills with fluid) and urachal chorda or urachal ligament (the entire tract persists as a cord) (Laverty and Salisbury 2002, Naiditch and others 2013). …”
