Summary & Timescale of the Data

The 3-year data collection period was from 1 January 2017 to 31 December 2019.

It is important to note that as a result of the COVID-19 crisis some surgeons and units may have been unable to submit all or any of their 2019 data.

Data summary

1884 SUI procedures were recorded from 95 Consultants at 87 centres in the United Kingdom (1737 procedures for England only), including 81 private patients from 26 Consultants.  

96% of the operations (1,656 of 1,726 recorded) proceeded with no reported complications. There were 70 cases (4%) in which a peri-operative complication was recorded. Of the 1,136 (60%) patients with follow-up recorded, 1,131 (99.6%) had a record of whether or not there was a post-operative complication.  For 1033 (91%) patients, no post-operative complications occurred.

There were no deaths during the study period.

74% (1388) of the procedures were performed for primary SUI and 26% (496) 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: 12 (range 1 - 92)
  • Median number of cases per centre:  12 (range 1 - 108)

HES figures for 2017 to 2019 (inclusive)  indicate that urologists undertook 2,444 stress urinary incontinence (SUI) procedures in England ( 993 in 2017,  721 in 2018 & 730 in 2019). The BAUS audit has, therefore, captured  around 71% of these.

Gynaecologists performed 10,483 SUI procedures in England during the same period ( 4,707 in 2017, 2,910 in 2018 & 2875 in 2019).

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 2017 to 2019 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.

Timeline for 2019 data

10 Feb 2020 Deadline for submission of data to BAUS
21 Feb 2020 Summaries of data returned to Consultant contributors for validation
23 Mar 2020 Final deadline for corrections and additional data
Mar/Apr 2020 Data was extracted from the web-based database. Once extracted, the data was transferred to a Microsoft Access™ database & Microsoft Excel™ spreadsheet, then imported into Tableau™ for generation of the final analyses.
