The orifices of the ureters are placed at the postero-lateral angles of the trigonum vesicae, and are usually slit-like in form.

In the contracted bladder they are about 2.5 cm. apart and about the same distance from the internal urethral orifice; in the distended viscus these measurements may be increased to about 5 cm.

Preliminary Evidence Suggests Periureteral Botulinum Toxin Type A Injection Improves Ureteral Stone Passage in the Porcine Model.

PURPOSE: We evaluated the use of periureteral injection of botulinum toxin type A (Botox®, BTX-A) to facilitate passage of ureteral stones in a porcine model. We believe that reducing detrusor muscle tone around the intramural ureter may facilitate passage of ureteral stones through the ureterovesi

INTRODUCTION: The management of primary obstructed megaureter (POM) ranges from temporary double-J stenting to conventional ureteric reimplantation with tapering. Of late, several authors have favored refluxing reimplantation. In the present study the outcomes of 'mini reimplantation', where no tape

INTRODUCTION: A duplex renal collecting system is a common congenital anomaly in children. Continuous dribbling (especially if after the toilet-training period) should raise suspicion of the presence of an ectopic ureter, which is most often associated with ureteral duplication.
