Surgical treatment of post abortum endometriosis of the bladder and postoperative bladder function

During the years 1953-1967, 17 women with endometriosis of the urinary bladder were treated with extirpation of the endometrial tissue, including partial or total resection of the trigone. In all cases the endometriosis had followed vaginal hysterotomy for legal abortion. Urethrocystoscopy was performed and the residual urine and bladder capacity were measured in all the patients one month and one year after the bladder operation. At follow-up in 1978 only 4 of the 17 women were available for urodynamic studies. Combined urethrocystometry, recording of the urethral pressure profile and measurement of the maximal urethral pressure in supine and standing positions were performed in these four patients, using the technique of Ulmsten et al. In all cases in the series, including those with trigone extirpation, all the tested parameters were normal. The writers therefore conclude that even total trigone resection can be done without disturbance to the bladder function.
