2. Figure 1
Distribution of deep endometriosis by localization and by size. Lesions larger than 4 cm are rare, whereas hydronephrosis is found predominantly in lesions larger than 3 cm. Ureteral lesions were found exclusively in women with hydronephrosis and/or in women with nodules larger than 4 cm (from Leuven database spanning 1989–2011).
