A prospective evaluation of the management of acute pyelonephritis in adults referred to urologists

Abstract

In order to assess whether it is appropriate and clinically efficient to admit adults with 'clinically diagnosed' acute pyelonephritis (APN) under urologists, as is current practice in many NHS hospitals, a prospective study was undertaken over nine months in an NHS teaching hospital. Thirty-nine patients with clinical APN were admitted to the urology unit; all were pyrexial and 30 (77%) had typical features of rigor, flank pain and irritative lower urinary tract symptoms. Twenty-one (54%) had positive urine cultures, 31 (79%) had parenteral antibiotics, while another three (7%) had oral agents initially. The remaining five (14%) were continued on agents initiated by their GPs before admission. Thirty-three (85%) had imaging procedures with eight significant anomalies being noted. Urgent invasive intervention was required in only four (10%) patients; length of stay varied from one to 25 days. Uncomplicated moderate to severe APN in adults may be treated safely without the need for admission to the urology unit, either in the outpatient setting or on an acute admissions observation ward. Complicated cases requiring intervention can be transferred to the urologist once recommended investigations have been undertaken. This care pathway may help to reduce cancellations of elective urological cases and is likely to be more cost-effective for the NHS by reducing unnecessary admissions.
