Malacoplakia of the seminal vesicles. Case report and particularities.

Objective: Malacoplakia is a rare chronic granulomatous disorder that mostly affects the urogenital system. This article describes a case of uncommon location of this disease at the level of the seminal vesicles and the clinical, imaging and histological particularities of this medical entity.

Method: We report the case of a 69 year-old male consulting for constitutional syndrome that presented a pelvic tumor on the image studies, possibly arising in the seminal vesicles.

[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.

[Post-traumatic renal arteriovenous fistula. Conservative treatment with superselective embolization].

Objective: Renal arterial-venous fistula is a low incidence clinical entity generally secondary to processes invasive to such organ. We report a new case with a bibliographic review, and evaluate the diagnostic and therapeutic approach.

Methods/results: We report the case of a patient who suffered a left flank knife wound and developed an arterial-venous fistula presenting with hematuria that was solved by selective embolization.
