A retrospective analysis of the factors associated with increased risk
of readmission within 30 days following primary transurethral resection
of bladder tumour
Abstract
Background Transurethral resection of bladder tumour (TURBT) is
associated with a perioperative morbidity of 5-10% which can lead to
unplanned readmissions. In this study, we aim to identify factors that
lead to an increased risk of unplanned readmissions within 30 days of
primary TURBT. Methods A retrospective study was conducted to identify
patients who had their primary TURBT at our institute from 2011-2019.
The clinico-demographic factors, history of smoking, intake of
anti-platelet drugs, co-morbidities, tumour size (< 3 cm or
> 3cm), multifocality and histopathological type were
abstracted. The patients who had a readmission were identified and
reasons for admission were recorded. Results A total of 435 patients
were identified. The median age was 66 years. There were 378 (86.9%)
males, 110 (25.3%) had history of smoking and 37 (8.5%) had history of
intake of an anti-platelet agent. In the cohort 166 (38.2%) were
diabetic, 239 (54.9%) were hypertensive, 72 (16.6%) had COPD, 78
(7.9%) had hypothyroidism. A total of 206 (47.4%) had a tumour of
>3cm, multifocality was seen in 140 (32.2%) while muscle
invasive tumour was present in 161 (37%) patients. A total of 22
(5.06%) had re-admissions within 30 days with hematuria being the
commonest etiology. On the univariate and multivariate analysis, history
of smoking ( p=0.006 and 0.008, respectively) or intake of anti-platelet
agents (p<0.001 and <0.001, respectively) were
significantly associated with increased unplanned readmission.
Conclusion Our study revealed smoking and intake of anti-platelet agents
as the factors leading to increased risk of unplanned readmissions.
