Randomized prospective trial comparing immediate versus delayed ureteroscopy for patients with ureteral calculi and normal renal function who present to the emergency department.

Patients And Methods: There were 271 consecutive patients who were enrolled in this prospective study. Patients were randomized to emergency ureteroscopy (group A) or delayed ureteroscopy (group B).

Seminal monolateral nerve-sparing radical prostatectomy in selected patients.

Introduction: In recent years there has been a shift in prostate cancer stage with the majority of patients nowadays being operated with cT1c disease, prostate-specific antigen levels of <10 ng/ml, and a decreased rate of seminal vesicle invasion. Recent data suggest the role of preservation of the seminal vesicle in improving continence and/or potency. We describe our preliminary experience with seminal-sparing, unilateral nerve-sparing retropubic radical prostatectomy.
