Background: The incidence of nephrolithiasis is increasing globally. It is a common presentation, with a reported incidence of 9% amongst the general population. The gold standard for treating obstructing ureteric or renal stones is via surgical intervention. These include nephrostomy, stent insertion and ureteroscopy. The National Institute for Health and Care Excellence (NICE) guideline recommends surgical treatment within 48 h of diagnosis. Delayed surgical intervention can lead increased morbidity including sepsis and renal failure. This audit examined adherence to this recommendation in University Hospital Limerick (UHL).

Methods: We retrospectively audited patients having the principal diagnosis of hydronephrosis with renal or ureteric obstructing calculus between January 2022 and December 2022. Data were collected from the Hospital In-Patient Enquiry (HIPE) office and our electronic handover record. Details of patient demographics, date and time of presentation at Accident & Emergency (A&E), clinical presentation, co-morbidity, date and time of surgical intervention, length of stay (LOS) were recorded. IBM SPSS 27 was used to analyse the data.

Results: A total of 98 patients were audited, median age 55 years [interquartile range (IQR): 40–77 years]. Median pre-operative LOS was 2 days (IQR: 0–8 days) and post-operative 1 day (IQR: 1–5 days). Median overall LOS was 3 days (IQR: 2–9 days). About 90% patients had double-J stent insertion. There were no mortalities.

Conclusions: Our median time to surgical intervention was 2 days, similar to the 48-hour standard set by NICE. There are several factors which may have contributed to the longer preoperative LOS such as theatre availability, bed availability and patient related factors. These factors will be investigated in a follow up audit.
