Priapism: an unusual complication of heparin therapy for sudden deafness.

Two cases of priapism occurring during heparin therapy for sudden hearing loss are reported. The association of anticoagulants and priapism is increasingly recognized. Literature studying possible mechanisms of the role of heparin in priapism is reviewed.

The use of self-retained ureteral stents in the management of urologic complications in renal transplant recipients.

Nineteen self-retaining ureteral stents were used to manage postoperative ureteral obstruction and fistulas in 12 renal transplant recipients. In 3 patients with ureteral obstruction and 2 with a fistula placement of the self-retaining stents for 4 to 6 weeks allowed the complication to resolve. In 3 patients with ureteral obstruction placement of the self-retaining stents allowed for stabilization of the condition and reduction of immunosuppression therapy before an open surgical repair.

Differential renal function using technetium-99m dimercaptosuccinic acid (DMSA): in vitro correlation.

The relationship between differential renal uptake of Tc-99m 2-3 dimercaptosuccinic acid (DMSA) and differential renal function was examined in normal and abnormal dogs by correlating Tc-99m DMSA localization with relative renal blood flow and creatining clearance. There was close correlation of fractional Tc-99m DMSA localization with relative renal function.
