Of 614 patients, with a BMI of 27,82 (overweight), 40% had mixed urinary incontinence and 60% pure stress urinary incontinence (SUI). Just one of them had previous surgery for stress incontinence (retropubic sling). There was persistence of stress incontinence in 17 patients (2,77%), and recurrence among the 5 years or more of follow up in 29 (4,72%) of them, with a medium time of recurrence of 2 years and 8 months. 21 (3,42%) presented de novo voiding disfunction. 100 (16,7%) related de novo urinary urgency. 30 (4,89%) started feeling pain or dyspareunia after the surgery. In 41 (6,68%) recurrent UTI was observed. There were no bladder erosions, and just 2 (0,33%) urethral erosions (4 years and 8 years after the surgery). In 4 patients (0,65%) the sling was found to be in intimate contact with the urethral wall in the ultrasound, but urethral erosion was not confirmed by cystoscopy, nor did the patient have any pain or recurrent UTI; one of them had de novo urgency, and another one had de novo voiding disfunction.
Regarding US measurements, we studied them individually about each specific possible complication:
-Voiding disfunction: of 21 cases, we just had US measurement on 6 (28,5%). 4 (66,6%) were at a distance of 2,5 mm or less to the urethra, and 4 of 5 (80%) at less than 15 mm from the bladder neck (there was 1 measurement missed). Medium distance to the complex was 2,45 mm, and medium distance to the bladder neck was 14,5 mm.
-De novo urgency: of 100 cases, we had US measurement on 51 (51%). One complex measurement was missed; of the other 50, 9 (18%) were of 2,5 mm or less. 12 bladder neck measurements were missed, and of the other 39, 24 (61,5%) were of 15 mm or less. Medium distance to the complex was 3,59 mm, and medium distance to the bladder neck was 16,27 mm.
-Pain/dispareunia: of 30 cases, just 13 (43,33%) US measurements were registered. 3 meshes (23,7%) were at 2,5 mm or less from the urethral complex, and 7 (53,84%) were at 15 mm or less from the bladder neck. Medium distance to the complex was 3,48 mm, and medium distance to the bladder neck was 16,6 mm.
-Recurrent UTI: of 41 cases, we only had US data recorded on 18 (43,9%). 6 (33,3%) were at 2,5 mm or less of the complex, and 10 (55,5%) were at a distance of 15 mm or closer to the bladder neck. Medium distance to the complex was 3,09 mm, and medium distance to the bladder neck was 14,4 mm.
-Persistent SUI: of 17 patients, we only have registered 4 US measurements. None of them was closer than 3,4 mm from the urethral complex. The medium distance was 5,2 mm. There were no recorded measurements of distance to the bladder neck.
-Recurrent SUI: of 29 women, we had US measurements on 14 (48,47%). 2 (14,28%) were at 2,5 mm or closer to the urethra. We missed 1 bladder neck distance measurement, and, from the other 13 cases, 7 (53,84%) were at 15 mm or less. Medium distance to the complex was 3,92 mm, and medium distance to the bladder neck was 18,04 mm.
