Summary & Timescale of the Data

The 3-year data collection period was from 1 January 2015 to 31 December 2017.

Data summary

2716 SUI procedures were recorded from 106 Consultants at 95 centres in the United Kingdom (2531 procedures for England only), including 191 private patients from 38 Consultants. One of the Consultants that returned data is not a BAUS member. 

96% of the operations where this was recorded (2,498 of 2,599) proceeded with no reported complications. There were 101 cases (4%) in which a peri-operative complication was recorded. Of the 1,733 (64%) patients with follow-up recorded, 1,709 (99%) had a record of whether or not there was a post-operative complication.  For 1543 (90%) patients, no post-operative complications occurred.

There were no deaths during the study period.

80% (2159) of the procedures were performed for primary SUI and 20% (557) 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: 20 (range 1 - 130)
  • Median number of cases per centre:  21 (range 1 - 126)

HES figures for 2015 to 2017 (inclusive) indicate that urologists undertook 3,524 stress urinary incontinence (SUI) procedures in England (1472 in 2015; 1059 in 2016; 993 in 2017); the BAUS audit has, therefore, captured data on 72% of these.

Gynaecologists performed 17,409 SUI procedures in England during the same period (7437 in 2015; 5265 in 2016; 4707 in 2017). It should be noted that HES shows a marked reduction in these procedures year on year from 2015 and, as a result, a number of centres no longer perform them.

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 2015 to 2017 data

12 Feb 2018 Deadline for submission of data to BAUS
20 Feb 2018 Summaries of data returned to Consultant contributors for validation
23 Mar 2018 Final deadline for corrections and additional data
Mar/Apr 2018 Data extracted from the web-based database. Once extracted, the data was transferred to a Microsoft Access™ database for validation before being imported into Tableau™ for generation of the analyses
18 Apr 2018 All contributing surgeons were sent a link to the BAUS website so they could see exactly how their data would be presented
