Volume 8, Supplement 4Review ArticlesThe Use of Alpha-Blockers for the Treatment of NephrolithiasisAdvances in Alpha-Blocker Therapy in the Management of Urological DisordersOjas D ShahMichael LipkinMedical expulsion therapy has been shown to be a useful adjunct to observation in the management of ureteral stones. Alpha-1-adrenergic receptor antagonists have been studied in this role. Alpha-1 receptors are located in the human ureter, especially the distal ureter. Alpha-blockers have been demonstrated to increase expulsion rates of distal ureteral stones, decrease time to expulsion, and decrease need for analgesia during stone passage. Alphablockers promote stone passage in patients receiving shock wave lithotripsy, and may be able to relieve ureteral stent–related symptoms. In the appropriate clinical scenario, the use of a-blockers is recommended in the conservative management of distal ureteral stones.

Volume 11, Number 1Case ReviewRenal Involvement by Chronic Myelomonocytic Leukemia Requiring NephroureterectomyRaavi GuptaElias S HyamsOjas D ShahJonathan MelamedSamir S TanejaChronic monomyelocytic leukemia (CMML) is a relatively rare clonal hematologic disorder with features of myelodysplastic syndrome and myeloproliferative disease. Renal impairment from CMML is infrequent and can result from both direct (ie, infiltrative) and indirect (eg, vasculitis, infarction) mechanisms. This case report describes a patient with refractory gross hematuria requiring nephroureterectomy with diffuse involvement of the upper tract by CMML and accompanying extramedullary hematopoiesis. Underscored are the need to maintain a broad differential diagnosis for upper tract lesions in the setting of gross hematuria, and the potential need for drastic measures to control upper tract bleeding if conservative measures fail.[Rev Urol. 2009;11(1):33-37]Gross hematuriaSecondary malignancy of kidneyLeukemia
Volume 16, Number 3Review ArticlesTaxi Cab Syndrome: A Review of the Extensive Genitourinary Pathology Experienced by Taxi Cab Drivers and What We Can Do to HelpDisease State ReviewOjas D ShahDavid S GoldfarbAlon Y MassThis review consolidates knowledge regarding the extensive genitourinary pathology experienced by taxi cab drivers. Taxi cab, livery, truck, and other drivers all objectively and subjectively may have more voiding dysfunction, infertility, urolithiasis, bladder cancer, and urinary infections as compared with nonprofessional drivers; this is called taxi cab syndrome. Together with governmental and medical assistance, simple interventions—such as education, the addition of taxi relief stations, and possibly the use of sanitary urinary collection devices—to curb the progression of genitourinary disease in taxi drivers should be prospectively studied. It is postulated that many of these interventions may also benefit other groups of occupationally related infrequent voiders.
