HaEmaturia After Transurethral resection of bladder Tumour (HEATT): A multicentre,regional collaborative analysis of factors associated with emergency re-admission with haematuria following TURBT

Abstract

Objective:

To calculate the re-admission rate with haematuria within 30 days of elective transurethral resection of bladder tumour (TURBT), and identify factors associated with this.

Materials and Methods:

This was a multicentre, retrospective audit, identifying all adult patients over the age of 16 who underwent elective TURBT between 1 September and 30 November 2019. Data were collected from medical records and operation notes on patient demographics, intra-operative factors and post-operative management. Primary outcome measure was the proportion of patients emergently re-admitted with haematuria. Secondary outcome measures were the re-operation rate for haematuria, and the rate of new acute thrombotic event (TE). Fisher’s exact test was used to calculate p values within subgroups for re-admission rates.

Results:

443 patients from 12 hospitals were included. Median age was 75 years (17–99). 15 patients (3.4%) were re-admitted with haematuria. Subgroup analysis demonstrated higher rate of re-admission for pre-existing antithrombotic agents (ATAs) (2.0% vs. 6.1%, p = 0.046), increased for non-Aspirin ATAs (10.5%, p = 0.0015). 52% of non-Aspirin ATAs were restarted within 48 hours of surgery; post-operative plan for restarting was not documented in 22.1%. One patient (0.23%) developed acute TE (pulmonary embolus).

Conclusion:

Pre-existing use of non-Aspirin ATAs is associated with increased risk of post-TURBT haematuria, with variable practice in post-operative recommencement.
