Methods and materials
Data was obtained retrospectively over a 12-month period (July 2017 to June 2018) from local radiology, biochemistry and theatre patient databases. Only admissions with acute obstructive uropathy were included. Admissions for routine exchange or removal of nephrostomy/stent as well as routine urology/stone management were excluded. Analysis of the data against agreed local recommendations was conducted (Fig. 1).
Information regarding level of obstruction was documented in patients only if clearly stated in the procedure report or coincident imaging. Sepsis was identified in patients where all the following parameters were met:
- blood results available on local biochemistry database,
- white cell count less than 4 or more than 12,
- C-reactive protein more than 5.
Age, length of inpatient stay and post-procedure deaths were analysed using the Mann-Whitney U test (Python 3). The distribution of management options among patients with and without sepsis and those with different levels of obstruction was analysed using the Chi-squared test (Microsoft Office 365 Excel).
