[Clinical case of penile fracture].

A clinical case of a penile fracture as a result of an unsuccessful sexual intercourse, which later required surgical treatment in the form of corporoplasty with opening and draining of the hematoma, is discussed in the article. Penile fracture is a rare urological emergency that requires immediate medical attention to avoid long-term complications, including penile curvature and erectile dysfunction.

What is the most dangerous sexual position that caused the penile fracture? A systematic review and meta-analysis.

PURPOSE: Penile fracture (PF) affects 1,14 to 10,48 men in every 100.000 men in East Asia, and the primary aetiology is sexual intercourse, but the knowledge regarding the most dangerous sexual position is not well explained. This study compares three sexual positions: man on top position (MTP), woman on top position (WTP), and doggy style position (DSP), leading to PF potential. MATERIALS AND METHODS: A search of sexual position-related PF in Google Scholar, PubMed, Cochrane, and PMC Europe was performed. Criteria inclusion was the full text of relevant articles which describ the number of sexual positions. It was analyzed by odds ratio, random model effect, and the OR and 95%CI were calculated. RESULTS: 12 relevant papers involving 490 patients comprised 169 MTP, 120 WTP, 158 DSP, and 43 no intercourse cases. Meta-analysis of all sexual positions was a MTP P= 0,04, WTP P=0,49, and DSP P=0,0005. CONCLUSION: The man-dominant positions (MTP and DSP) were significantly potential for PF, which speculated that when a man is dominant and very excited, intercourse may become highly vigorous and impact trauma. This study found that man's dominant position consists of DSP and the MTP significantly lead to PF.

Honey dressing for penile skin avulsion caused by traditional circumcision: a case report.

OBJECTIVE: Penile skin avulsion is a rare complication of circumcision but commonly encountered as the result of traditional practice. We aimed to present the use of honey dressing and the benefit of its wound healing properties for management of such a complex wound. CASE: A 24-year-old male patient with penile bleeding presented to the emergency department after undergoing traditional circumcision. Complete degloving of the penis with active bleeding and foul odour, along with heavy contamination of chewed betel leaves and powdered amoxicillin was found. Honey (Madu Nusantara, PT. Madu Nusantara, Indonesia) was used as dressing after copious irrigation using saline and povidone-iodine with bleeding control. RESULTS: Honey dressing was shown to be effective for secondary wound healing of such a complicated and contaminated wound-in this case due to its antimicrobial, anti-inflammatory, immunostimulatory and autolytic debridement properties. A complete re-epithelialisation of the wound was achieved without progression to the hard-to-heal state by day 43. Suboptimal sexual function and aesthetic result due to wound contracture were observed as surgical reconstruction via split-thickness skin graft was refused due to cost. CONCLUSION: In this case report, honey dressing was shown to be effective for wound healing, even in a penile avulsion with complete skin loss and heavy contamination. In rural settings, where penile avulsion due to traditional circumcision is common, honey should be considered as one of the dressing choices.

Biodegradable nano black phosphorus based SDF1-α delivery system ameliorates Erectile Dysfunction in a cavernous nerve injury rat model by recruiting endogenous stem/progenitor cells.

Stem cell (SC) therapy has been shown high prospects in erectile dysfunction (ED) treatment. Without ethical issues and risks of immune rejection and tumorigenesis of exogenous SC therapy, endogenous stem/progenitor cells (S/PCs) have a better potential for ED management, and their homing and redistribution are controlled by SDF1-α/CXCR4 axis. Considering black phosphorus nanosheet (BPNS) has emerged as an efficient and safe drug vehicle due to its large surface area, biodegradability, and the ability to retain and slowly release its loaded drugs, BPNS is utilized to load SDF1-α, a chemokine for S/PCs, to construct the BP@SDF1-α complex to efficiently recruit stem cells (SCs) by injury-site injection and thus ameliorate ED within the bilateral cavernous nerve injury (BCNI) rat models. We find that BP@SDF1-α can efficiently recruit exogenous SCs and endogenous S/PCs to corpus cavernosum and main pelvic ganglion (MPG) by local administration. Of note, ascribing to endogenous S/PCs recruitment, it also successfully alleviates ED in BCNI rat models by enhancing the protein expression levels of α-SMA, CD31, and nNOs, and eliciting less collagen deposition in the penis after its combined injection at corpus cavernosum and MPG. Thus, this study provides a new insight into the treatment of ED with endogenous S/PCs. BIODEGRADABLE NANO BLACK PHOSPHORUS BASED SDF1-α DELIVERY SYSTEM AMELIORATES ERECTILE DYSFUNCTION IN A CAVERNOUS NERVE INJURY RAT MODEL BY RECRUITING ENDOGENOUS STEM/PROGENITOR CELLS.

A review of the literature and proposed algorithm for penile fracture management.

INTRODUCTION: In the management of penile fractures, immediate surgical repair has resulted in better outcomes when compared with a conservative approach; however, there is currently no consensus on the treatment of patients presenting beyond the immediate period (>24 hours) following injury. OBJECTIVES: To examine the latest literature on management strategies in penile fracture and propose an optimal algorithm for the treatment of patients with delayed presentation. METHODS: A comprehensive search was conducted following the PRISMA-P 2020 guidelines. A search was performed in several databases with the following strategy: ("Penile fracture" OR "fracture of penis" OR "rupture of corpora cavernosa" OR "rupture of tunica albuginea") AND (management OR treatment OR surgery OR "surgical reconstruction" OR "surgical repair"). This resulted in 108 relevant articles. Two independent reviewers screened these articles according to the inclusion criteria. Full-text review of 56 articles was performed, and ultimately 20 studies were selected. Measures included the use of diagnostic imaging, timing of surgical repair (immediate, <24 hours after injury; delayed, >24 hours), surgical approach, and long-term complications (ie, erectile dysfunction and penile curvature). RESULTS: The review highlighted the benefits of immediate surgical repair in penile fractures, demonstrating improved patient outcomes. Furthermore, it found that surgical repair should be considered even in cases with delayed presentation (>24 hours after injury). To better evaluate the long-term impact of delayed surgical intervention on patient outcomes, we recommend standardized postoperative follow-up, with routine assessments of erectile function and penile curvature. CONCLUSION: Contemporary literature suggests that immediate and delayed surgical repair of penile fractures leads to adequate postoperative outcomes, and patients presenting >24 hours after injury should still be considered for surgery.

[Clinical effects of autologous split-thickness skin grafting for prefabricating urethra combined with scrotal flap in repairing middle urethral defect with penile defect].

Objective: To investigate the clinical effects of autologous split-thickness skin grafting for prefabricating urethra combined with scrotal flap in repairing middle urethral defect with penile defect. Methods: The retrospective observational study was conducted. Eight male patients (aged 14 to 58 years) with middle urethral defect and penile defect caused by various injuries who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Medical University from January 2015 to January 2022. The length of urethral defect was 3 to 5 cm, and the wound area of penile defect after debridement was 5.0 cm×2.5 cm to 7.0 cm×5.5 cm. All the patients underwent autologous split-thickness skin grafting for prefabricating defect urethra in stage Ⅰ, and urethral anastomosis was performed and unilateral scrotal flap was transferred to reconstruct urethra and penis in stage Ⅱ. The area of scrotal flap was 6.0 cm×3.0 cm to 8.0 cm×6.0 cm. The wound in the donor area of skin graft was covered by oil gauze, and the wound of flap donor area was sutured directly. On the 7th day after the operation of stage Ⅱ, the survival of the flap was observed. In 3 weeks after the operation of stage Ⅱ, the urinary flow rate was measured by the urinary flow rate detector (urinary flow rate >15 mL/s was regarded as unobstructed urination), the urinary fistula and erectile function were observed, and the self-made therapeutic satisfaction questionnaire was used to investigate the therapeutic satisfaction degree of patients. During follow-up, the appearance of the flap recipient area was observed, the Vancouver scar scale (VSS) was used to evaluate the scar situation in the donor areas of skin graft and flap, the urinary flow rate was detected as before, the urethral stricture, urinary fistula, and erectile function were observed, and the therapeutic satisfaction degree of patients was investigated. Results: On the 7th day after the operation of stage Ⅱ, the flaps survived completely in 8 patients. In 3 weeks after the operation of stage Ⅱ, the urinary flow rate was 25.3 (18.0, 38.5) mL/s, with unobstructed urination, without urinary fistula and with erectile function, and the score of therapeutic satisfaction degree was 14.3 (14.0, 15.0). During follow-up of 1 to 7 years, the flap recipient area of 8 patients was full in appearance and not swollen, with similar color to the surrounding tissue; the VSS scores of the donor areas of skin graft and flap were 11.5 (10.0, 13.0) and 10.5 (9.3, 12.0), respectively, the urinary flow rate was 24.6 (17.7, 34.1) mL/s, with no urethral stricture, urinary fistula, and erectile dysfunction, and the score of therapeutic satisfaction degree was 13.5 (13.3, 14.8). Conclusions: Autologous split-thickness skin grafting for prefabricating urethra combined with scrotal flap in repairing the urethral and penile defects not only reconstructs the structure of urethra and the shape of penis, but also restores the sensation and erectile function of penis, with few postoperative complications, no obvious scar hyperplasia, and high satisfaction degree of patients, which is worthy of clinical promotion.

Functional recovery of injured cavernous nerves achieved through endogenous nerve growth factor-containing bioactive fibrous membrane.

Radical prostatectomy is a highly successful treatment for prostate cancer, among the most prevalent manifestations of the illness. Damage of the cavernous nerve (CN) during prostatectomy is the main cause of postoperative erectile dysfunction (ED). In this study, the capability of a personalized bioactive fibrous membrane to regenerate injured CN was investigated. The fibrous membrane bioactivity is conferred by the selectively bound nerve growth factor (NGF) present in the rat urine. In a rat model of bilateral CN crush, the implanted bioactive fibrous membrane induces CN regeneration and restoration of erectile function, showing a significantly increased number of smooth muscle cells and content of endothelial and neuronal nitric oxide synthases (eNOS; nNOS). In addition, the bioactive fibrous membrane promotes nerve regeneration by increasing the number of myelinated axons and nNOS-positive cells, therefore reversing the CN fibrosis found in untreated rats or rats treated with a bare fibrous membrane. Therefore, this personalized regenerative strategy could overcome the recognized drawbacks of currently available treatments for CN injuries. It may constitute an effective treatment for prostate cancer patients suffering from ED after being subject to radical prostatectomy. STATEMENT OF SIGNIFICANCE: The present work introduces a unique strategy to address post-surgical ED resulting from CN injury during pelvic surgery (e.g., radical prostatectomy, radical cystoprostatectomy, abdominoperineal resection). It comprises a bioactive and cell-free fibrous implant, customized to enhance CN recovery. Pre-clinical results in a rat model of bilateral CN crush demonstrated that the bioactive fibrous implant can effectively heal injured CN, and restore penile structure and function. This implant selectively binds NGF from patient fluids (i.e. urine) due to its functionalized surface and high surface area. Moreover, its local implantation reduces adverse side effects. This tailored regenerative approach has the potential to revolutionize the treatment of ED in prostate cancer patients following radical prostatectomy, overcoming current treatment limitations.

[The role of doppler ultrasound in the scrotal and penile trauma].

INTRODUCTION: The injuries of the external genital organs in men accounts for 30-50% of the total number of injuries of genitourinary system. In half of the cases, there is a trauma of the penis. In 80% of cases, trauma of the penile or scrotal area occurs. AIM: To study the role of Doppler ultrasound in diagnosing injuries of the scrotum and penis. MATERIALS AND METHODS: The analysis of Doppler ultrasound study of the scrotum and penis in 32 patients with injuries of the external genital organs was carried out. RESULTS: The analysis revealed various ultrasonographic variants of damage to the penis and scrotum. In the vast majority of cases, scrotal trauma without testicular rupture (n=15; 46%) and with testicular rupture (n=11; 33%) was seen. Penile injury was diagnosed in 6 (19%) patients. CONCLUSION: Doppler ultrasound is a gold standard for diagnosing injuries of the scrotum and penis. The mandatory ultrasound study allows to determine the indications and type of salvage surgical procedure.

Introduction: Circumcision is one of the most frequent urologicalsurgical procedures in the pediatric population globally. Complications,although rare, can be severe.Clinical case: We present the case of a Senegalese 10-year-oldmale patient who had undergone ritual circumcision in his early childhood and developed a progressive circumferential tumor in the penilebody with no further associated symptoms. Surgical exploration was carried out. A fibrotic-looking penile ring, which was interpreted asan injury secondary to the non-absorbable suturing material used inthe previous surgery, was identified. The tissue involved was removed,and on-demand preputioplasty was conducted. Due to technical limitations, the resected tissue could not be analyzed, which means diagnosiscould not be histopathologically confirmed. The patient had a favorableprogression. Conclusions: This case demonstrates that the medical personnelin charge of performing circumcisions should be adequately trained inorder to prevent severe complications.(AU)

The presentation and outcomes of penile fracture with associated urethral injury: A systematic literature review.

PURPOSES: Penile fracture (PF) with associated urethral injury has been described as a rare condition yet a serious urological emergency. We conducted this systematic review to address the current literature concerning the etiology, presentations, intra-operative findings, site of injury, and complications of PF with associated urethral injury, Materials and Methods: The present systematic review was limited to human-based studies published in English language, and reporting clinical data on PF cases with associated urethral injuries. A comprehensive search of the literature was conducted on five electronic databases from their inception to May 2022: Medline via PubMed, Web of Science, Google Scholar, Scopus, and EBSCO host. RESULTS: A total of 15 studies were included encompassing 1671 patients with PF. Out of 1665 patients with PF retrieved from the case series studies, 65 patients had associated urethral injuries giving a point prevalence of 3.9%. The vast majority of the patients had blood on the meatus and hematuria suggestive of urethral injury (57/59; 96.6%). Forty patients had partial urethral disruption and the rest of the patients had a complete rupture. All patients received primary urethroplasty as the main modality of treatment. The median hospital stay was two days and the median duration of transurethral catheterization was 21 days. Five patients (8.5%) developed urethral stricture; other complications included penile curvature (6.7%), palpable fibrosis (6.7%), and erectile dysfunction (3.4%). CONCLUSIONS: Urethral injuries are uncommon, but serious findings, in patients with PF. Primary urethroplasty appears to achieve satisfactory outcomes with a low incidence of short and long-term complications.

Characterization of genital injuries secondary to foreign bodies from 2011 to 2020.

PURPOSE: To identify demographic trends of foreign object genital injuries presenting to emergency departments from 2011 to 2020. MATERIALS AND METHODS: The National Electronic Injury Surveillance System database reports consumer product-related injuries in United States ED visits. The database was queried to identify 375 cases of genital injuries from 2011 to 2020. Inclusion criteria consisted of cases reporting injuries involving the urethra, penis, or scrotum. Data was reported and analyzed using linear regression. RESULTS: Based on 375 cases, an estimated 13,170 (95% confidence interval, 10,817-15,522) patients in the US suffered genital injuries due to foreign bodies between 2011 and 2020. These injuries involved the penis (65.9%), urethra (30.7%) and scrotum (3.5%). Of all patients, 11.8% required hospital admission after treatment of which injuries to the urethra were most common (44.0%). Most of these patients were ages 19 to 64 (66.1%). Consumer products most implicated included rings (50.7%), zippers (17.1%), and pens and pencils (10.3%). Injuries due to zippers and swimming apparel occurred significantly more frequently in patients ages 0-18 (p<0.05). Injuries due to kitchen gadgets occurred significantly more in patients ages ≥65 (p<0.05). Pens, pencils, and massage devices were items that routinely resulted in urethral injuries, often requiring hospitalization. Linear regression showed genital injuries related to foreign objects significantly increased from 2011 to 2020 (p<0.001). CONCLUSIONS: Due to the nature of injury caused to genitalia by intentional and unintentional exposure to foreign bodies, educating individuals on this topic in sexual education classes is necessary for preventing future injuries.

Injectable thermo-sensitive hydrogel containing ADSC-derived exosomes for the treatment of cavernous nerve injury.

Radical pelvic surgery is commonly accompanied by the risk of postoperative erectile dysfunction induced by cavernous nerve injury (CNI-ED). The strategy of using adipose mesenchymal stem cell-derived exosomes (ADSC-Exo) to treat neurodegenerative diseases has shown promising results. However, it remains challenging to prolong the retention of unbound ADSC-Exo in damaged tissues to exert therapeutic effects. Herein, we develop a novel injectable thermo-sensitive hydroxyethyl chitosan/sodium ß-glycerophosphate hydrogel (HG) encapsulating ADSC-Exo (HG@Exo) to manage CNI-ED. The HG exhibits excellent injectability, structural stability, and body temperature sensitivity. In vivo assessment demonstrates that the designed ADSC-Exo-loaded HG hydrogel enhances the retention of ADSC-Exo and displays a slow release. Furthermore, when HG@Exo is applied to the site of nerve injury, erectile function in the bilateral cavernous nerve injury rat model is significantly improved. Thus, our finding indicates that the developed bioactive hydrogel presents a promising strategy for the effective management of CNI-ED.

A case of a high-flow priapism treated with superselective transcatheter embolization.

High-flow priapism is a rare condition characterized by prolonged and painless erection. It is defined as contusion or thrombosis of the cavernous body of the penis usually secondary to blunt trauma. Due to the rarity of the disease, there is no well-defined consensus about treatment. Conservative treatment is often applied with non-steroidal anti-inflammatory drug. We present a case of 58-year-old man with proximal partial priapism that developed secondary to blunt trauma to the penis. The patient did not benefit from non-steroidal anti-inflammatory drug therapy and then was successfully treated with selective embolization.

Genital Mutilation in Males.

PURPOSE OF THE REVIEW: Genital mutilation in males can range from minor injuries (cuts from a blade) to severe urological emergencies (testicular or penile amputation). Due to the rarity of these events, there is a lack of extensive reports, as most of the available literature is regarding single cases. Genital mutilation has been associated with psychotic and non-psychotic causes, psychiatric conditions, drug consumption, sexual practices, or even cultural or religious beliefs. It is crucial to perform a psychiatric evaluation of these patients to obtain the best therapeutic approach. This manuscript serves as a review of the currently available knowledge regarding male genital mutilation. RECENT FINDINGS: A great variety of reasons have been associated with genital mutilation. Previous authors have distinguished between those that present with a clear mental health precursor from cases with no psychotic background. Nevertheless, sometimes, it is difficult to make this distinction. Recently, reconstructive techniques for amputation cases have moved towards a microsurgical approach in order to improve outcomes. A holistic therapeutic approach must be performed to increase the chances of effective treatment. Close collaboration between urologists, psychiatrists, and emergency doctors is essential to ensure the best care for patients performing genital mutilation. Future publications must evaluate differences in treatment options and the impact that these have on the long-term well-being of patients undergoing genital self-mutilation.

[PENILE STRANGULATION CAUSED BY A METALLIC RING SUCCESSFULLY TREATED BY PENILE PUNCTURE PLUS BLOOD REMOVAL INSTEAD OF DESTROYING THE RING].

A 63-year-old man visited our hospital with a complaint of penile swelling caused by metallic ring entrapment in the penis. He had put the ring around his penis 4 hours prior and was subsequently unable to remove it. We attempted to remove the ring using a ring cutter but that was unsuccessful. We then inserted two 18 G needles into the corpus cavernosum through the glans penis and removed blood by manual compression according to a technique called the "string method." The swelling gradually decreased, and we successfully removed the ring without destroying it. The total duration of strangulation was about 5 hours. The patient was subsequently discharged after ensuring he had no urinary difficulties. No complications were observed during the follow-up period.In almost all penile strangulation cases caused by hard objects, such as metallic rings, reported in Japan, the objects were typically destroyed and penile puncture and blood removal, as was performed in our case, was rare. Although penile puncture and blood removal is not commonly performed in Japan, this technique can be performed quickly and inexpensively in the emergency room and should be considered an initial treatment for penile strangulation caused by hard objects.

The challenges and complications of re-implantation of the penis following amputation.

Amputation of the penis is a rare and devastating injury. The etiologies vary from accidental, self-inflicted to attacks due to sexual jealousy and revenge. In the present era of microvascular surgery, replantation is the standard care. However, replantation of the penis comes with its own set of difficulties and complications. Knowledge of the anatomy and prior knowledge of the possible complications makes the surgeon aware of the course of events after a replantation. It helps in devising strategies to overcome these challenges methodically. We present a case of penile replant with the complications that we encountered, and the measures are taken to counter them on our way to a successful outcome. Funding: No external funding.
