Abstract

Purpose:

Ureteroscopy is increasingly used to manage nephrolithiasis, upper urinary tract urothelial carcinoma and other urological conditions. In this study we determine the rate of readmission and emergency department visits after ureteroscopy in an underserved population, as well as factors associated with these unplanned visits.

Materials and Methods:

A retrospective chart review from 2010 to 2014 of all elective ureteroscopies was conducted at a single tertiary hospital serving an underserved population in a major metropolis. Demographic, operative and discharge characteristics were collected and analyzed.

Results:

A total of 276 ureteroscopies were performed with 15.6% presenting to the emergency department within 30 days. Overall 5.8% were readmitted. Readmitted patients were more likely to have hypertension (OR 3.64, p=0.02), asthma or chronic obstructive pulmonary disease (OR 5.54, p=0.001), 2 or more comorbidities (OR 3.65, p=0.12), or a complication associated with ureteroscopy (OR 7.27, p=0.007). The patients who sought care in the emergency department after ureteroscopy were less likely to have had a ureteral stent in place before ureteroscopy (OR 0.35, p=0.017) or an endoscopic urological procedure within the last 30 days (OR 0.35, p=0.045). About two-thirds of patients who presented to the emergency department complained of pain alone, while the most common complaints for readmitted patients were fever and pain (43.8%).

Conclusions:

The majority of emergency department visits after ureteroscopy were due to pain. These patients were less likely to have a preoperative ureteral stent placed or a history of recent urological procedures. Readmission rates were associated with overall comorbidities and complications.
