Traumatic emergencies of the external genitalia are relatively uncommon and affect young people [1]. These traumas represent less than 1% in Africa [1], 8% - 10% in Europe [2], 2% - 10% Asia [3], 1% America [4] and 1.9% in the Middle East [5]. The etiologies are multiple and the lesions may involve the penis and/or the scrotal contents (testicle, epididymides, cord) in men and the vulva in women. The diagnosis of these injuries is most often clinical in the case of open trauma or fracture of the penis, and may involve ultrasound in the case of a large post-traumatic bursa [2]. They may lead to urinary complications and sequela (erectile dysfunction, curvature of the penis during erection, urethral stricture, testicular atrophy) and serious psychological harm [2]. The management of external genitalia trauma is done in an emergency setting and may include trimming in case of a wound or surgical exploration of the traumatized bursa and finally cavernous suture for penile fractures [3]. This management strategy therefore requires a rigorous clinical evaluation with a precise and complete lesion assessment. Treatment must be early to minimize complications and sequela. The aim of our study was to describe the epidemiological, clinical and therapeutic aspects of traumatic emergencies of the external genitalia in the urology department of the University Hospital of Bouaké.

This is a retrospective and descriptive study which took place in the urology department of the university hospital of Bouaké. The study took place from January 1, 2012 to December 31, 2018, during which we collected all cases of traumatic External Genitalia Organs (EGO) emergencies that were treated in the department. The study period registered 26 patients. The study included male and female patients of all ages who were treated medically or surgically for EGO trauma emergencies. There were no exclusion criteria. The parameters studied included: socio-demographic data: (age, profession, sex), clinical: (circumstances of occurrence, aetiology, consultation time, site of injury, associated injuries), paraclinical (imaging), therapeutic (surgical procedure, evolution, postoperative complications, hospitalization time). The data were collected from the patients' files, a survey form and the register of surgical reports of patients operated on for traumatic emergencies at the EGO. All data were entered into the WORLD software and processed with Epi info 2.10.

In our study, the minimal age of the patients was 34.5 years with extremes of 16 and 52 years. The young age has been reported by several authors in the literature. Bah in Senegal reported in his study an average age of 37 years [6]. Ouattara in Benin noted an average age of 32.3 years [7]. Djè in Côte d’Ivoire found an average age of 27.8 years [8]. The averages confirm on the one hand that this type of lesion concerns the most active population and on the other hand that young people constitute the most important part of the populations of developing countries. Trauma to the external genitalia is a male prerogative and almost all authors agree on this characteristic [8] [9]. 96.2% of our study involved men. This predominance of males was noted by Dekou, in his study of 27 cases of trauma to the genital-urinary system, who reported 26 male patients out of a series of 27 patients [1]. This strong male predominance in our series could be explained by the greater exposure of men to public road accidents. We noted one case of trauma to the vulva. This is a rare case and this rarity has been noted in the literature [8]. In our series, closed scrotal trauma was the most frequent reason for admission with 30.8%. This observation was made by Coulibaly in Mali [9], and Kambou in Burkina-Faso [10]. Open trauma was infrequent as reported in the literature [10], most often secondary to a firearm. The circumstances of occurrence of trauma to the bursa and vulva were dominated by road accidents with 63.6%. Our results are in line with those of Kambou in Burkina Faso [10] and Djè in Côte d’Ivoire [8], who found 45% and 75.6% respectively. These different results show that public road accidents are the greatest source of trauma. The main circumstance for the occurrence of penile trauma was coitus error, i.e. 36.4%. This result is similar to the literature [11] [12] [13]. The clinical symptomatology of trauma to the genital-urinary system is well known [6] [7]. It consists of:

­ A haematocele which is clinically expressed as an enlarged, normally colored;

­ A scrotal haematoma which is characterized by an enlarged, ecchymotic, dark red bursa on pale skin. Sometimes it is a localized deformity.

In our series, the clinical symptomatology was dominated by scrotal swelling in 26.9% followed by penile swelling in 23.1%.

Our results corroborate those of Coulibaly in Mali [9] and Andry in Switzerland [14]. The increase in the volume of the scrotum could be explained by the violence of the trauma on the scrotum on the one hand, and by the presence of a scrotal haematocele or haematoma on the other. As for the swelling of the penis, it can be explained by the presence of a haematoma opposite the fracture site of the corpora cavernosa. From a paraclinical point of view, ultrasound of the bursa is necessary because the physical examination makes it difficult to diagnose lesions of the epididymis, the testicles or the cord, and above all because it is very sensitive due to the pain. Combined with Doppler, it can show areas of localized ischaemia in the case of compressive haematocele, intra-testicular haematoma or rupture of the albuginea [6]. However, its specificity is not perfect, sometimes leading to surgical exploration to make a complete assessment of the lesion [15]. In our work, the diagnosis was mainly made on the basis of clinical findings followed by an emergency operation. Ultrasound was not systematic. Six patients (23.07%) underwent scrotal ultrasound. Our attitude is in line with that of several authors, notably Djè [8] and Coulibaly [9], who recommend emergency surgical exploration except in cases of moderate trauma. This management would reduce the risks of complications and sequela. The therapeutic attitude to bursal trauma is variable and depends above all on the presence or absence of a haematocele on clinical examination [10]. Thus, in the absence of a haematocele and in the presence of an intact testicle on ultrasound, the medical treatment consists of analgesics, non-steroidal anti-inflammatory drugs in the absence of contraindication of gastro duodenal ulcers, antibiotic coverage, anti-tetanus sero-vaccination associated with suspension of bursaries [10], as was the case for two (2) of our patients, i.e. 7.7%. In our series, we used local-regional anaesthesia in 91.66% of cases. We chose spinal anaesthesia because of its advantages, which allow surgery to be performed with ease and comfort [16]. Surgical management consisted of an exploratory scrototomy followed by emergency evacuation of a scrotal haematoma in 29.16% of cases. This attitude, motivated by the acute traumatic bursa, has been noted by other authors [17] [18]. Our approach corroborates the rule according to which in the case of an acute large bursa, surgical exploration should not be delayed. In our series, all patients admitted for fracture of the corpora cavernosa were approached by circumferential sub coronal incision, because it allows an exhaustive diagnosis of the lesions. Evacuation of the haematoma followed by haemostasis and repair of the albuginea was done with 3/0 Vicryl using separate stitches followed by closure of the skin with separate stitches; a dry dressing was done in 45.5% of cases, i.e. 5 cases. Post-operatively, all patients received oral medication based on diazepam at a dose of 10 mg per day for a fortnight, and non-steroidal anti-inflammatory drugs for a week. Probabilistic antibiotic therapy was prescribed in our series based on cephalosporin until the eighth day after surgery as some authors [17] [18]. All patients admitted for open trauma received trimming. One patient had orchiectomy on the right side and trimming. Our treatment was due to the fact that the patient presented with open gunshot trauma to the scrotum with disruption of the right testicle. We performed trimming plus haemostasis in one patient due to traumatic avulsion of the testis. Dekou reported four (4) cases of orchiectomy in his study of trauma to the genitourinary system [1]. This finding reflects the violence of the trauma. Our series reports a case of open trauma to the vulva following a road traffic accident. It was a perineal impaction against the ground. Our management consisted of trimming and suturing of the labia minor and major with 3/0 Vicryl. This reconstructive surgery was performed in collaboration with gynaecologists. Trauma to the external genitalia involving the vulva is extremely rare [19]. The only case reported in seven years of practice confirms this rarity. Animal bites are rare as evidenced by our study but potentially serious [20]. Wolf et al. report four cases of dog bites [19]. Cummings and Boullier reported eight (8) cases treated for scrotal dog bites [20]. However, in the largest series in the literature, Gomes et al. report ten (10) new cases: eight (8) cases were attacked by dogs, one by a horse and one by a donkey [21]. The morbidity is directly related to the severity of the bite and the delay in consultation. These animal bites carry a triple infectious risk: bacterial, tetanic and rabies [15]. Broad spectrum antibiotic therapy should be administered. In our series, one case of dog bite was observed. The bite involved the body of the penis. Wound trimming combined with anti-rabies prevention and anti-tetanus sero-vaccination were carried out according to the vaccine recommendations [21]. The most common bacteria isolated in animal bites are streptococci and staphylococci, Escherichia coli, associated with anaerobic germs. In our case, no germ was identified, hence the choice of broad-spectrum antibiotic therapy. In our series, two patients had associated lesions. It was a traumatic rupture of the urethra and a fracture of the obturator frame, i.e. 7.69%. The bone lesion was managed by orthopaedic surgeons. The urethral injury was not treated as an emergency. It was done as a delayed emergency as recommended by Leguillou in Bordeaux and Gueye in Dakar between the 8th and 10th day [22] [23] and Diallo in Conakry [24]. Our patient was operated on as a delayed emergency after organization of the lesions and at a distance from the inflammatory and infectious processes. This approach of management at a distance from the trauma was that adopted by Dje and Fall [8] [25]. In our series, more than 60% of patients had a hospital stay of less than five days after treatment. Our duration is in line with that of Coulibaly in Mali [9]. However, some authors such as Kambou et al. in Burkina Faso [10] reported a longer hospital stay of 40.4 days after treatment. The postoperative period was marked by necrosis of the contralateral testicle in a patient who had undergone a right orchiectomy following a gunshot trauma with testicular damage. We performed a second orchiectomy; this unfortunate situation could be explained by microscopic lesions of the cord elements of the left testicle which would have led to secondary ischaemia and then to necrosis of the testicle. This highlights the importance of informing any patient with open bursal trauma of the risks of possible castration and its consequences. According to Bah et al. [15], the possibility of sperm conservation should be considered with the patient. In our case, this option had been proposed to him but he did not consider it appropriate, as he had already fathered 8 children. The possibility of sperm conservation for assisted reproduction was of lesser importance. We observed testicular atrophy which was managed by preventive left orchiectomy. This post bursal trauma complication has been observed in approximately 50% of patients in the series by Cross et al. [26]. The mechanisms of occurrence of testicular atrophy are not well known: post-traumatic lesions of the micro-vascularization of the testis; ischaemia by compression due to oedema and haematoma and autoimmune mechanisms are mentioned in the literature [27]. However, this study has limitations which must be taken into account when interpreting the results. As this is the retrospective nature with significant loss of information, its relatively small size does not give it sufficient statistical power.

Taumatic emergencies of the external genital organs are uncommon, but it is potentially serious because it can lead to urinary or sexual complications with major consequences for fertility. These injuries are rare in women and very frequent in men. The diagnosis is most often based on clinical examination. However, clinical examination is often difficult because of pain and/or swelling, hence the importance of ultrasound. Trauma to the bursa is most often encountered in road accidents. As for penile trauma, it is secondary to a false step in the coitus and emergency treatment is surgical in most cases. In women, surgical management must be carried out in a multidisciplinary context involving urologists, gynaecologists and psychologists of both sexes. Animal bites of external genital organs are rare but serious and carry a significant infectious risk. Morbidity is related to the severity of the bite and the delay in consultation. Surgical treatment must always be combined with medical treatment and vaccination. Complications and sequela of EGO trauma are formidable. These complications must be explained to the patient before treatment in order to reduce the medico-legal problems associated with trauma.

The patients were informed and agreed to participate in the study, and their anonymity was preserved.
