In male small ruminants, voiding disturbances are not uncommon. A precise knowledge of the underlying disease is essential for prognostic evaluation as well as for a decision concerning the therapeutic approach. Common reasons for voiding disturbances in the male small ruminant are obstructive urolithiasis, traumata of the penis or inflammatory processes within the urethra or urinary bladder. The diagnostic method of choice - in addition to clinical examination - is diagnostic imaging. Because radiology is not always possible under field conditions, the aim of this article is a detailed presentation of ultrasonography of the distal urethra of the male lamb...

Hypospadias, the abnormal position of the urethral orifice, is considered a rare congenital malformation of the reproductive organs in male dogs. We present 5 new cases of hypospadias - 2 of the penile type in German Shepherd Dogs and 3 perineal types in a Bavarian Mountain Hound, a French Bulldog, and an American Staffordshire Terrier. Other abnormalities (rudimentary or underdeveloped penis, incompletely formed preputial sheath, and bilateral cryptorchidism) were also observed. Molecular analysis of all cases revealed the presence of Y-linked genes (SRY and ZFY)...

INTRODUCTION: Re-operative penile reconstruction is challenging and requires tension-free skin closure. The repair popularized by Cecil and Culp in the 1940s, using the scrotum to provide a temporary vascularized bed for complex hypospadias repairs, fell out of favor due to temporal trends towards single-stage repairs and concern for utilizing hair-bearing skin on the penile shaft. OBJECTIVE: It was hypothesized that a modified Cecil-Culp (CC) concept of penile scrotalization, leaving the penis attached to the scrotum for 1 year rather than 6 weeks as originally described, improves outcomes with this reconstruction for ventral skin deficiency or poor vascular support...

OBJECTIVES: To propose a simple classification system for buried penis repairs and present an analysis of perioperative data based on category. METHODS: Patients undergoing buried penis repair at a single institution were examined. Classification was as follows: Category I - Penile Unburying with Local Flap; II - Skin Graft; III - Scrotal Surgery; IV - Escutcheonectomy; V - Abdominal Panniculectomy. Complex repairs were Category III or above. Success was defined as an unburied penis without additional unburying surgery...

BACKGROUND: Peyronie's disease (PD) is a chronic fibrotic disease of the penis affecting a significant number of men worldwide without effective medical treatments. Myofibroblasts are pivotal in the pathogenesis of PD. Adenosine and adenosine receptors have been suggested to be involved in the pathophysiology of fibrosis. AIM: To understand the role of adenosine receptors in myofibroblast transformation in PD. METHODS: Fibroblasts were isolated from the non-PD tunica albuginea (TA) tissue and PD plaque tissue and were transformed into myofibroblasts using transforming growth factor (TGF)-β1...

OBJECTIVES: To allow for organ preservation, high dose rate brachytherapy may be used in the treatment of localized penile cancer. Penile cancer is a rare malignancy, accounting for less than one percent of cancers in men in the United States. The standard treatment for localized disease is partial amputation of the penis. However, patients with T1b or T2 disease, less than 4 cm in maximum dimension and confined to the glans penis may be treated with brachytherapy as an organ-sparing approach...

BACKGROUND: Rear tip extenders (RTEs) are used commonly in penile prostheses, but their effect on erectile rigidity has not been extensively studied. AIM: To determine whether RTEs affect erectile rigidity in inflatable penile prostheses and determine what length of RTE should be used for a given corporal length-in this case, 22 cm. METHODS: To assess the effect of RTEs on erectile rigidity, we created a penile model simulating 2 corpora cavernosa that accommodated cylinders of varying lengths...

In this article we have presented a case of 31-year-old male with thickening of the skin and tender cord of superficial veins of the penis and laboratory findings of the high titer of PM/Scl-100 antibodies in the serum. The patient was referred to the Rheumatology Department due to suspected systemic sclerosis. The HRCT scan of his lungs revealed fibrous degeneration and ground-glass opacity in the lower lobes. Capillaroscopy showed abnormalities, which were not typical for systemic sclerosis. In Doppler ultrasound examination of penis, superficial dorsal and circumflex veins thrombosis and inflammatory infiltration were observed...

Background: Neurofibromatosis is a genetically inherited disorder of the nervous system (brain and spinal cord) which mainly affects the development of nerve (neural) cell tissues, causing tumors (neurofibromas) to develop on nerves. It is the most common single gene disorder of the nervous system and inheritance is through autosomal dominance. They are usually classified into types 1 and 2, the type 1 is the commoner type and also known as superficial neurofibroma. Plexiform neurofibromas are the next most common type of tumor in individuals with type 1 neurofibroma...

Urethral cancer (UC) is a rare malignancy with a poor prognosis. Since local recurrence is common and associated with morbidity, case series have reported on the use of adjuvant radiotherapy. Radiotherapy treatment setup for malignancies of the penis can be challenging because of variability in anatomic positioning. This variability can lead to lack of reproducibility. We propose a novel external beam radiotherapy technique for the treatment of UC: prone positioning. This technique has been used to treat breast cancers successfully and can be used to treat any variety of penile malignancies...

Morphological characterisation of the genital organs of primates may bring significant contributions to the understanding of different reproductive behaviours and support new conservation strategies. However, relevant or detailed descriptions of genital morphology of several primate species are still lacking. This study describes the gross and microscopic anatomy of the internal and external genitalia of Marca's marmoset (Mico marcai). The same organs described in other primate species were identified here, but some anatomical particularities were detected, such as absence of a dartos tunic, presence of a vas deferens ampulla, absence of spongious erectile tissue in the pelvic urethra, separation of prostate gland lobes by a longitudinal sulcus and lack of septation in the corpus cavernosus and spongiosus at the level of the shaft and free portion of the penis...

INTRODUCTION: Fistulas are a common complication of hypospadias surgery; they are more frequent after mid-shaft and posterior hypospadias repair. Surgical treatment of fistula still remains challenging with a significant failure rate. The basic principle is to add layers between skin and neourethra in order to decrease the incidence of recurrent urethrocutaneous fistula (UCF). We report our experience of UCF repair using a vascularized tunica vaginalis flap (TVF) after posterior and mid-shaft hypospadias surgery...

Vitamin D deficiency is common in pregnant women and infants. The present study aimed to investigate the effects of vitamin D restricted diet on the Wistar rats offspring penis morphology. Mother rats received either standard diet (SC) or vitamin D restricted (VitD) diet. At birth, offspring were divided into SC/SC (from SC mothers, fed with SC diet) and VitD/VitD (from VitD mothers, fed with VitD diet). After euthanasia the penises were processed for histomorphometric analysis. The VitD/VitD offspring displayed metabolic changes and reduction in the cross-sectional area of the penis, corpus cavernosum, tunica albuginea, and increased area of the corpus spongiosum...
