Cited in Scopus: 0A 66-year-old male presented with five days of penile pain and ulceration. The patient had a history of stage 5 chronic kidney disease and repeatedly declined hemodialysis. Wound and urine cultures were unrevealing. CT of the abdomen and pelvis did not reveal any evidence of Fournier's gangrene but identified diffuse severe calcific vasculopathy. Urology and dermatology agreed on the diagnosis of penile calciphylaxis. While diagnosis of calciphylaxis often includes histologic evidence of obstructive vasculopathy, biopsy of penile calciphylaxis is contraindicated due to increased morbidity and mortality. - Pediatric Case Reports
First Case of a Term Male Born with Aphallia and Complete Urethral Atresia
UrologyVol. 156e127–e130Published online: May 31, 2021- Rachel P. Vaizer

Cited in Scopus: 0Aphallia is an exceedingly rare condition often associated with an array of genitourinary anomalies. Classically, aphallia was thought to have to co-exist with a urethral fistula for adequate urine outflow to avoid the sequelae of oligohydramnios, while the absence of a fistula has historically been incompatible with life. We report the first case of a prenatally unrecognized aphallia with complete urethral atresia in a full-term baby, without an associated fistula or ectopic urethra. We postulate a urachal cyst noted on prenatal ultrasound resolved into a patent urachus providing sufficient outflow to avoid sequelae of oligohydramnios and allowed for term birth.
