HealthDay News — Most patients who present to the emergency department after undergoing elective ureteroscopy complain of pain alone, according to a study published in The Journal of Urology.

Jonathan Bloom, MD, from New York Medical College in Valhalla, and colleagues conducted a retrospective chart review from 2010 to 2014 of all elective ureteroscopies at a single tertiary hospital serving an underserved population. The author collected and analyzed demographic, operative, and discharge characteristics for 276 ureteroscopies.

The researchers found that 15.6% of ureteroscopy patients presented to the emergency department within 30 days; 5.8% were readmitted. Readmitted patients were more likely to have hypertension, asthma or chronic obstructive pulmonary disease, 2 or more comorbidities, or a complication linked to ureteroscopy (odds ratios, 3.64, 5.54, 3.65, and 7.27, respectively). Patients who sought care in the emergency department after ureteroscopy were less likely to have had a ureteral stent in place before ureteroscopy or an endoscopic procedure within the previous 30 days (odds ratios, 0.35 and 0.35). Most patients (about two-thirds) who presented to the emergency department had a complaint of pain alone, while readmitted patients most often complained of fever and pain (43.8%).

“The majority of emergency department visits after ureteroscopy were due to pain,” the authors write. “These patients were less likely to have a preoperative ureteral stent placed or a history of recent urological procedures.”
