[Urinary lithiasis treatment by laparoscopy. Combined techniques.].

Over the last 30 years, the treatment of urinary lithiasis has changed dramatically. With the advent of extracorporeal lithotripsy and the advances on ureterorenoscopy and percutaneous nephrolithotomy, the need to turn to open and laparoscopic/robotic surgery has diminished. The objective of this article is to review the different indications for open and/or laparoscopic treatment of urinary lithiasis, to achieve its complete elimination with the less invasive possible means and trying to minimize the number of secondary procedures as well as complications.

Bilateral obstructive uropathy secondary to giant periureteral diverticulum.

Bladder diverticula are herniations of the mucosa through the fibers of the bladder muscle connected by necks of variable amplitude. They are often asymptomatic, although they may lead to complications that require a surgical therapeutic approach. We report the case of a patient with bilateral obstructive uropathy secondary to a giant periureteral diverticulum that was treated by diverticulectomy and reimplantation of the left ureter in the bladder.
