Internet and postal survey of endourologic practice patterns among American urologists

Purpose: We determine endourological practice patterns among American urologists for the management of distal ureteral calculi, ureteropelvic junction obstruction, staghorn calculi and the use of ureteral stents with extracorporeal shock wave lithotripsy (ESWL dagger). Materials and Methods: Surveys were mailed by the United States postal service to 1,000 American urologists selected randomly from the American Urological Association membership roster. The same survey was sent via the Internet to 3,065 American urologists with an electronic mail address listed in the roster. Results: Responses were received from 1,029 urologists (postal 601, Internet 428). Ureteroscopy was the preferred treatment for all distal ureteral calculi less than or equal to 10 mm. Acucise double dagger endopyelotomy was the most frequently selected therapy for adults with ureteropelvic junction obstruction (50.3%, 514 of 1,022). Open pyeloplasty was recommended by a significantly greater percentage of urologists in practice longer than 15 years compared with the remaining survey respondents (166 of 485, 34.2% versus 92 of 427, 21.5%). For patients with renal pelvic stones 10, 15 or 20 mm. who are treated with ESWL routine stent placement was preferred by 25.3% (259 of 1,022), 57.1% (584 of 1,022) and 87.1% (888 of 1,019) of urologists, respectively. Percutaneous nephrolithotomy was preferred for patients with staghorn calculi by 80.5% (828 of 1,028) of survey respondents. Conclusions: Most urologists follow the American Urological Association practice guidelines for patients with distal ureteral calculi and staghorn stones. There is a significant difference of opinion regarding the use of stents with ESWL. No clear consensus has been reached concerning the management of adults with ureteropelvic junction obstruction. These data may be useful in designing physician education programs and/or future investigations to help define standard treatment practices for urological diseases.
