Case Report: Penile necrosis associated to paraphimosis with calciphylaxis due to terminal chronic kidney disease.

Background: Penile necrosis is a rare condition that may present in patients with diabetes mellitus or chronic kidney disease (CKD). The recommended treatment is controversial. We report a case of penile necrosis in a diabetic patient caused by episode of paraphimosis associated with uremic arteriopathy treated with partial amputation. Clinical Case: A 53-year-old male with a background of arterial hypertension, diabetes mellitus and CKD in hemodialysis. The patient presented with paraphimosis and glans necrosis. An emergency circumcision was carried out. A doppler ultrasound found fluid collection in the left corpus cavernosum, parietal vascular calcifications and vascular insufficiency in the corpus cavernosum that suggested necrosis. A partial amputation of the penis was carried out. After three years of follow-up, the outcome has remained favorable. Conclusions: Penile necrosis is a rare but serious complication of terminal CKD. In these patients, systemic calciphylaxis is usually observed. The main take-away lesson is that a multidisciplinary approach is necessary.

Necesidad de circuncisión o dilatación del prepucio. Estudio de 1.200 casos / The need of circumcision or prepuce dilation. A study with 1200 boys

Objetivos: Demostrar el incremento de la retractilidad del prepucio con la edad. Señalar la poca utilidad de la circuncisión y la dilatación forzada del prepucio en la infancia. Métodos: El desarrollo del prepucio y su retractilidad, a medida que avanza la edad, fueron evaluados en 1200 niños de 0 a 16 años. El prepucio fue catalogado en tipos I a V según fue de menor a mayor su retractilidad en todos los casos que habían sido o no dilatados previamente. Resultados: La retractilidad del prepucio en los niños menores de un año en el tipo I (no retráctil) fue 63,4 %, mientras en el tipo V (completamente retráctil) fue tan solo 3,7 %. Lo contrario se observó en los adolescentes (11 a 16 años) en los que el tipo I fue 0,9 %, mientras el tipo V se observó en 80,9 %. También se encontró que 309 niños (43,1%) de los 717 niños que habían sido dilatados forzadamente su prepucio, cuando eran mas pequeños, tenían prepucios tipos I al IV, es decir, habían adquirido nuevamente adherencias balano-prepuciales en el momento del examen para nuestra investigación. Se observó que 17 niños de los examinados (0,4%) estaban necesitados de que se les realizara circuncisión. Ningún niño sufrió infección del tractus urinario superior. Conclusiones: Todos los niños nacen con el prepucio cubriéndole el glande, si no tienen una anomalía congénita del pene, manteniendo unas adherencias entre ambas estructuras, las que van desapareciendo con la edad, siendo total la separación en la pubertad, en la mayoría de los niños. Por ello consideramos la circuncisión o la dilatación forzada del prepucio innecesaria en la mayoría de los niños (AU)

Objectives: To demonstrate the increase of preputial retractability with age. To point out the small usefulness of circumcision and preputial forced dilation during childhood. Methods: The development of the prepuce and its retractability were evaluated in 1200 boys between 0 and 16 years. The prepuce was classified as type I to V depending on its lower or higher retractability in all cases having been dilated previously or not. Results: Prepuce retractability in boys under one year was type I (not retractile} in 63.4%, whereas it was type V (completely retractile) in only 3.7%. The contrary was observed in adolescents (11 to 16 years), in which type I was 0.9% and type V was observed in 80.9%. It was also observed that 309 boys (43.1%) among the 717 with previous prepuce forced dilation, had types I to IV prepuces, so, they had acquired new balanopreputial adherences by the time of examination for our study. Seventeen boys (0.4%) required circumcision. No children suffered upper urinary tract infections. Conclusions: All boys are born with the prepuce covering the glans penis, keeping adherences between both structures, which disappear with age, being the detachment complete at the time of puberty in most boys. So, we consider circumcision or forced dilation of the prepuce unnecessary in most boys (AU)

Manually assisted ejaculation in a stallion with erectile dysfunction subsequent to paraphimosis.

A Thoroughbred stallion with erectile dysfunction following paraphimosis was managed to allow consistent ejaculation. Ejaculation was elicited in this stallion by applying manual stimulation to the base of the penis. This technique allowed consistent ejaculation, and the stallion was able to return to natural service. Historically, stallions with this degree of penile dysfunction have been considered incapable of ejaculation and unable to continue as breeding animals.

Acute urinary retention: causes and treatment.

Acute urinary retention often is secondary to obstruction of the bladder or distal genitourinary system, which may be induced by any of a number of medical or surgical conditions. Treatment varies according to the cause.
