The double urethra: revisiting the surgical classification

Abstract

The double urethra is a diverse spectrum comprising different pathologies. Our proposed classification system of duplicated urethras is clinically relevant as it guides surgical management and allows prognostication of outcome.

Urethral Duplication with Two Hypospadic Meati—An Unusual Variant

“…5,11,12 A general consensus is that each patient should be considered individually, with no standard fit-all approach really being suitable for all cases of a particular lesion. 13 Some authors would tend toward using the orthotopic urethra, even if it is hypoplastic; Ortolano and Nasrallah first proposed progressive urethral dilation to achieve adequate caliber. 14 We believe, as suggested by Salle et al, that after dilatation of the accessory urethra the risk of inadequate urine flow is high.…”

<p>Complete Urethral Duplication: Case Report and Literature Review</p>

“…In a literature review, we found that 4 different classification systems are available for this anomaly. [3][4][5][6] The Effman et al 3 classification system describes 3 types of urethral duplication that vary depending on the radiological location of the accessory urethra [ Figure 8]. In the first, Type I, there is a blind-ending accessory urethra (incomplete urethral duplication), and this condition is further classified into two subclasses, Type I-A and I-B.…”

“…Different classification systems for this anomaly were reported in the literature. [3][4][5][6] In most previously reported cases, the accessory urethra ends most commonly with a dorsally opened urethra (epispadias) but can also end in a ventrally opened midline urethra.…”

A new variant of urethral duplication- collateral urethral duplication with paraspadiac meatus: A case report

“…It usually occurs with duplication of urinary bladder, midline defect or caudal duplication. Anomalies associated with this are complete bladder duplication, thoracic hemivertebrae, supralevator imperforate anus, rectourethral fistula, vesicoureteral reflux, partial sacral agenesis [8] and duplication of external genitalia [2]. Collateral urethral duplication without associated midline anomaly is quite rare [3].…”
