Urinary incontinence following obstetric fistula repair

Table 1 Summary of Classification according to Goh¹⁰ with the 3 parameters

Type: distance from fixed reference point (external urinary meatus)

Type 1 - distal edge of fistula > 3.5 cm from external urinary meatus

Type 2 - distal edge 2.5-3.5 cm

Type 3 - distal edge 1.5-2.5 cm

Type 4 - distal edge < 1.5 cm

Size: Largest diameter in centimetres

Size a < 1.5 cm

Size b 1.5-3 cm

Size c > 3 cm

Special considerations

Special considerations i – none or mild fibrosis and/or vaginal length > 6 cm, normal capacity

Special considerations ii – moderate or severe fibrosis and/or marked reduction in vaginal length and/or capacity

Special circumstances iii –e.g., post-irradiation, ureteric involvement, circumferential fistula, previous repair
