Erect Penis

Penile fracture is an uncommon urological emergency, especially in Bangladesh. The other name is traumatic rupture of the tunica albuginea and corpora cavernosa in the erect penis. It occurs when an erect penis face to buckle under the pressure of a blunt sexual trauma. Patient gives the typical history of immediate detumescence, severe pain, swelling and eggplant deformity of the penile shaft due to penile injury. Immediate surgical exploration and repair of corpora Cavernosa with tunica albugenia is the most effective treatment modality. In normal cases diagnosis is made from history, physical examination alone. In some special cases ultrasonogram, radiological images, including retrograde urethrography or cavernosography are mandatory for proper diagnosis.

AbstractCurrent materials used in biomedical devices do not match tissue’s mechanical properties and leach various chemicals into the body. These deficiencies pose significant health risks that are further exacerbated by invasive implantation procedures. Herein, we leverage the brush-like polymer architecture to design and administer minimally invasive injectable elastomers that cure in vivo into leachable-free implants with mechanical properties matching the surrounding tissue. This strategy allows tuning curing time from minutes to hours, which empowers a broad range of biomedical applications from rapid wound sealing to time-intensive reconstructive surgery. These injectable elastomers support in vitro cell proliferation, while also demonstrating in vivo implant integrity with a mild inflammatory response and minimal fibrotic encapsulation.

Penile fracture is an underreported surgical emergency. It usually occurs as a single rupture of the tunica albuginea in one of two corpora cavernosa; a rupture of both masses is an uncommon finding. We report a case of a young male who presented to the emergency department two hours after sustaining penile trauma. Prompt surgical exploration was performed four hours post-injury. He was found to have one fracture on each corpora cavernosa, without urethral injury, which were repaired successfully. The patient had a favorable recovery and was discharged on the third postoperative day without complications. The aim of this report is to highlight the importance of complete degloving of the penile shaft for a meticulous search during surgery to avoid missed injuries. This approach will ensure a successful outcome avoiding physical and psychological disabilities.

Background: To evaluate two pediatric patients with syndromic craniofacial anomaly that underwent craniofacial reconstructive surgery using resorbable plate-screw systems which have been claimed as biodegradable fixation materials and used in craniofacial reconstructive procedures owing to their advantages such as adequate biomechanical resistance, longer dwelling time, elimination through physiological routes without causing any foreign body reaction and/or significant sequale. Patient and Method: Resorbable plate-screw systems used in 2 patiens for craniofacial reconstructive procedures such as bilateral fronto-orbital advancement and segmental right orbita (four wall box) osteotomy were evaluated as for their efficacy. Result: Adequate fixation was obtained in both patient, but Infection complication was seen in segmental right orbita osteotomy patient that appear localized abcess formation on subciliary incision and fronto medial insicion. After drainage insicion and antibiotic administration for 1 week, the infection was relieved. Summary: Owing to resorbable copolymer which contain a polyester derivate of L- lactidc and glycolic acid are ideal fixation materials used favourably in pediatric craniofacial reconstructive surgery and have further advantages such as adequate biomechanical resistance against distraction and compression forces in the early postoperative period, longer dwelling time and elimination from the body through physiological routes without causing any foreign body reaction.

The One

Previous biomechanical models of the penis that have attempted to simulate penile erections have either been limited to two-dimensional geometry, simplified three-dimensional geometry or made inaccurate assumptions altogether. Most models designed the shaft of the penis as a one-compartment pressurized vessel fixed at one end, when in reality it is a two-compartments pressurized vessel, in which the compartments diverge as they enter the body and are fixed at two separate points. This study began by designing simplified two-dimensional and three-dimensional models of the erect penis using Finite Element Analysis (FEA) methods with varying anatomical considerations for analyzing structural stresses, axial buckling and lateral deformation. The study then validated the results by building physical models replicating the computer models. Finally a more complex and anatomically accurate model of the penis was designed and analyzed. There was a significant difference in the peak von-Mises stress distribution between the one-compartment pressurized vessel and the more anatomically correct two-compartments pressurized vessel. Furthermore, the two-compartments diverging pressurized vessel was found to have more structural integrity when subject to external lateral forces than the one-compartment pressurized vessel. This study suggests that Mother Nature has favored an anatomy of two corporal cavernosal bodies separated by a perforated septum as opposed to one corporal body, due to better structural integrity of the tunica albuginea when subject to external forces.

Urethral Lesion

A 22-year-old man reported cracking sound and acute pain during sexual intercourse followed by rapid penile detumescence and ecchymosis. He experienced more pain because he could not urinate and had a palpably full bladder. Moreover, his urethra was bleeding. Physical examination revealed swollen, ecchymotic and deviated penis and penis ultrasonography showed an injury of the tunica albuginea and Buck’s fascia with an expanding hematoma. Suprapubic catheter was positioned. Surgical exploration revealed a tear of tunica albuginea of both corpora cavernosa and complete urethral dissection. End-to-end urethral anastomosis and suture of corpora cavernosa lesion were performed. Vescical catheter was mantained for 6 days and suprapubic catheter for 3 months to allow a complete urethral healing. A pseudo diverticulum was found atanastomosis level on the urethrocistography 1 month after surgery. It disappeared by allowing micturition via the suprapubic catheter. The patient presented regular urinary flow and physiological erections 30 days later. In our experience, prompt surgical repair preserved erectile function and keeping the suprapubic catheter protected the urethra; this was the correct management for repairing the urethral lesion.
