Urothelial carcinoma of the fossa navicularis successfully treated with laser ablation and distal urethrectomy: A case report

Primary urothelial carcinomas very rarely arise from the fossa navicularis of the penis. They are rarely reported in the literature, with only 13 cases reported thus far. Herein, we present the case of a 34-year-old man with bloody urethral discharge due to a mass detected by cystourethroscopy in the fossa navicularis. Biopsy confirmed the diagnosis of noninvasive urothelial carcinoma. The patient was managed successfully with two sessions of holmium laser ablation, followed by distal urethrectomy. After the treatment, the patient's erectile function and continence were preserved, and no tumor recurrence was observed after 1 year of follow-up.

FLAP METHOD WHEN OPERATING ATRESIAE ANI VE- STIBULARIS

As you know, anomalies in the development of the anal orifice are divided: into complete atresia - when it is completely absent, and into incomplete, when the aperture, being placed in a normal place, is too narrow to pass fecal masses (stenosis), or the intestine opens on some in another place, either in the back wall of the vagina along its length behind the hymen (abouchement retro-hymenal), or in front of it; ex. въ fossa navicularis (abouch. ant-hymenal). In embryonic life), the rectum and urogenital parts open in the urogenital sinus or cloaca, formed from the connection of the gradually deepening genital sulcus with allantois, the opening of the Mllerian canal and rectum, and the intestine is separated from the Mllerian canal by a plate and the fetus crotch tissue.
