Dorsal urethral diverticulum of the fossa navicularis: symptoms, diagnosis and treatment.
Spotting of blood per urethram, hematuria and episodic painful voiding in boys are not uncommon symptoms, although often the causes are not known. The lacuna magna of the urethra on the glans penis can cause such symptoms, as is demonstrated in this report of 4 cases. Treatment was surgical, which resulted in the immediate cure and relief of symptoms. Our study indicates that radiography of the terminal urethra, probing and endoscopy of the fossa navicularis should be done regularly to determine whether the lacuna magna is the enigma of the symptom complex.
