Relationship between site and size of bladder endometriotic nodules and severity of dysuria.

STUDY

OBJECTIVE

The purpose of this study was to evaluate the relationship between frequency/severity of dysuria with anatomic location and diameter of bladder endometriotic lesions.

DESIGN

Retrospective analysis (Canadian Task Force classification II-3).

SETTING

Tertiary care university hospital.

PATIENTS: Forty-one patients with bladder endometriosis (endometrial glands and stroma microscopically diagnosed to infiltrate the muscularis propria).

INTERVENTIONS: Laparoscopic partial cystectomy, preoperative scoring of dysuria using 10-point verbal analog scale (VAS).

MEASUREMENTS AND MAIN

RESULTS

Records of all patients with bladder endometriosis were assessed for frequency/severity of preoperative dysuria, anatomic location (base or dome), and diameter of bladder endometriotic nodule. Basal bladder lesions were observed in 18 (43.9%) of 41 patients versus 23 (56.1%) of 41 in the dome. Of the patients with basal lesions, 14 (77.8%) of 18 had preoperative dysuria versus 8 (34.8%) of 23 with dome lesions. Mean VAS score was 8.5 +/- 2.37 and 5.75 +/- 1.91 for base and dome lesions, respectively. Preoperative dysuria was found in 22 (53.7%) of 41 patients. Mean lesion diameter in patients with dysuria was 25.0 +/- 12.6 mm versus 16.3 +/- 6.8 mm in patients without dysuria.

CONCLUSION

Frequency and severity of preoperative dysuria were significantly higher in patients with basal endometriotic nodules. There was a positive correlation between severity of dysuria and lesion diameter.
