PURPOSE The American Urological Association convened the Ureteral Stones Clinical Guidelines Panel to analyze the literature regarding available methods for treating ureteral calculi and to make practice policy recommendations based on the treatment outcomes data. MATERIALS AND METHODS The panel searched the MEDLINE data base for all articles related to(More)
OBJECTIVES To review the diagnosis and treatment of ureteroarterial fistulas and to develop a management algorithm. Long-term ureteral stenting, along with pelvic surgery and radiotherapy, have led to an increased incidence of ureteroarterial fistulas. Experience diagnosing and treating these fistulas has been limited to case reports. METHODS A(More)
The American Urological Association Nephrolithiasis Clinical Guidelines Panel recommendations for managing struvite staghorn calculi are based on a comprehensive review of the treatment literature and meta-analysis of outcome data from the 110 pertinent articles containing viable, unduplicated data. The panel concluded that the 3 most significant outcome(More)
PURPOSE SWL has revolutionized the management of nephrolithiasis and it is a preferred treatment for uncomplicated renal and proximal ureteral calculi. Since its introduction in 1982, conflicting reports of early adverse effects have been published. However, to our knowledge the long-term medical effects associated with SWL are unknown. We evaluated these(More)
Nephrolithiasis is an important manifestation of autosomal dominant polycystic kidney disease (ADPKD), which occurs in approximately 20% of patients. It should always enter the differential diagnosis of flank pain in patients with ADPKD. The diagnosis is hindered by the distorted anatomy of the polycystic kidneys and the frequent occurrence of parenchymal(More)
PURPOSE We compared a current cohort of patients who underwent ureteroscopy to a cohort from the early 1980s to determine changes in success, indications and long-term complications of the procedure. MATERIALS AND METHODS A chart review was performed of 194 patients who underwent 209 ureteroscopic procedures at our institution during 1992. This group was(More)
PURPOSE Matrix stones are an uncommon form of urinary calculi and may be mistaken for tumors involving the renal collecting system, thereby presenting a diagnostic and therapeutic dilemma to the practicing urologist. MATERIALS AND METHODS From 1980 to 2003 we identified 5 patients with urinary matrix stones referred to our tertiary medical center for(More)
Despite the frequency and morbidity of nephrolithiasis in autosomal dominant polycystic kidney disease (ADPKD), this association has not been subject to a detailed study. One hundred fifty-one of 751 ADPKD patients seen at the Mayo Clinic between 1976 and 1986 had nephrolithiasis. Seventy-four had passed calculi or had stones surgically removed. Stone(More)
In a series of 506 patients with renal cell carcinoma survival was analyzed in terms of pathologic stage, histologic grade, and a combination of stage and grade. Data reveal that stage, grade and the combination are important prognostic indicators. Invasion of the renal pelvis is not an important factor in staging the disease. Women had a better survival(More)
