Summary & Timescale of the Data

The 3-year data collection period was from 1 January 2016 to 31 December 2018.

Data summary

2133 SUI procedures were recorded from 103 Consultants at 88 centres in the United Kingdom (1989 procedures for England only), including 112 private patients from 41 Consultants.  

90% of the operations (1,906 of 2,133) proceeded with no reported complications. There were 72 cases (3%) in which a peri-operative complication was recorded. Of the 1,367 (64%) patients with follow-up recorded, 1,359 (99.5%) had a record of whether or not there was a post-operative complication.  For 1249 (91%) patients, no post-operative complications occurred.

There were no deaths during the study period.

78% (1659) of the procedures were performed for primary SUI and 22% (474) for recurrent SUI. All data were entered by hand, and there was no bulk uploading of data from other systems.

  • Median number of cases per consultant: 16 (range 1 - 111)
  • Median number of cases per centre:  17.5 (range 1 - 100)

HES figures for 2016 to 2018 (inclusive)  indicate that urologists undertook 2,773 stress urinary incontinence (SUI) procedures in England (1059 in 2016; 993 in 2017 and 721 in 2018). The BAUS audit has, therefore, captured 72% of these.

Gynaecologists performed 13,242 SUI procedures in England during the same period ( 5265 in 2016; 4707 in 2017 and 2910 in 2018).

It should be noted that HES shows a marked reduction in these procedures year on year due to the mesh review and, as a result, a number of centres no longer perform them. 

Cumulative analysis of 2016 to 2018 SUI data

Surgery for recurrent SUI

Surgery for recurrent incontinence is likely to be more complex. Our data show that patients undergoing surgery after a previous failed incontinence procedure are:

  • more likely to be catheter dependent after surgery,
  • more likely to leave the operating room (OR) with a catheter in place,
  • less likely to be able to pass urine after surgery,
  • more likely to start unplanned clean intermittent self-catheterisation (CISC),
  • slightly more likely to have peri-operative complications, and
  • twice as likely (2% vs 1%) to have post-operative Clavien Dindo complications of Grade III level or greater.
