Indwelling ureteral stents as definitive therapy for distal ureteral calculi.
Distal ureteral calculi are a common urological problem often requiring surgical and anesthetic intervention. In a health care system with limited resources this intervention can lead to the expenditure of significant monies. Ureteral stents are often used to stabilize symptomatic patients preoperatively. Since stent placement causes passive ureteral dilation, we hypothesized that temporary placement of a ureteral catheter would facilitate spontaneous calculus passage. We prospectively studied 27 patients who presented with distal ureteral calculi less than 10 mm. large and met criteria established for surgical intervention. Self-retaining Double-J stents were placed in 10 male and 7 female patients, and left for 2 weeks using only topical anesthesia during the procedures. In the majority of the patients (83%) the calculi passed spontaneously after stent removal, obviating surgical or anesthetic intervention.
