Urethral Diverticulum with Lithiasis
European Urology, 1979 Urethral diverticulum, either congenital or acquired, is very rare and becomes symptomatic when complicated by infection and lithiasis. This paper reports on such a case that was cured by radical excision of the lesion.

Renal lithiasis and nutrition [PDF]
Nutrition Journal, 2006 Renal lithiasis is a multifactorial disease. An important number of etiologic factors can be adequately modified through diet, since it must be considered that the urine composition is directly related to diet. In fact, the change of inappropriate habitual diet patterns should be the main measure to prevent kidney stones.
