[Diverticulectomy and cricopharyngeal myotomy for the treatment of Zenker's diverticulum. a presentation of 33 cases].

Introduction: The classic treatment of Zenker's diverticulum (ZD) has been cricopharyngeal myotomy (CPM), with the need or not to resect it being argued (diverticulectomy versus diverticulopexy). However, the advance of endoscopic techniques requires new treatment strategies to be established. We analyse the complications and clinical results of our series with cricopharyngeal myotomy and diverticulectomy in patients with ZD.

[Treatment of childhood lithiasis using extracorporeal shock wave lithotripsy].

Objectives: We evaluated the efficiency of extracorporeal shock wave lithotripsy (ESWL) in the treatment of pediatric urolithiasis, analyzing results and complications in our series.

Methods/results: 20 patients (16 males and 4 females) with ages from 2 to 17 years were evaluated. Twelve patients presented left side lithiasis (60%).

[Extracorporeal shock-wave lithotripsy as treatment of lithiasis in horseshoe kidney].

Objectives: Horseshoe kidney is the most frequent renal congenital anomaly, with an estimated general population prevalence of 1/400-500. This entity may be asymptomatic for the entire lifetime, or produce symptoms from associated complications such as lithiasis, hydronephrosis, or recurrent infections. The incidence of lithiasis varies between 20% and 80% of the patients.
