INTRODUCTION
Although oral phosphodiesterase 5 inhibitors represent a first choice and long-term option for about half of all patients with erectile dysfunction (ED), self-injection therapy with vasoactive drugs remains a viable alternative for all those who are not reacting or cannot tolerate oral drug therapy. This current injection therapy has an interesting history beginning in 1982.
OBJECTIVES
To provide a comprehensive history of self-injection therapy from the very beginnings in 1982 by contemporary witnesses and some members of the International Society for Sexual Medicine's History Committee, a complete history of injection therapy is prepared from eyewitness accounts and review of the published literature on the subject, as well as an update of the current status of self-injection therapy.
METHODS
Published data on injection therapy, as a diagnostic and therapeutic tool for ED, were reviewed thoroughly by PubMed and Medline research from 1982 until June 2023. Early pioneers and witnesses added firsthand details to this historical review. Therapeutic reports of injection therapy were reviewed, and results of side effects and complications were thoroughly reviewed.
RESULTS
The pioneers of the first hours were Ronal Virag (1982) for papaverine, Giles Brindley (1983) for cavernosal alpha-blockade (phentolamine and phenoxybenzamine), Adrian Zorgniotti (1985) for papaverine/phentolamine, and Ganesan Adaikan and N. Ishii (1986) for prostaglandin E1. Moxisylyte (thymoxamine) was originally marketed but later withdrawn. The most common side effect is priapism, with the greatest risk of this from papaverine, which has modified its use for therapy. Currently, prostaglandin E1 and trimixes continue to be the agents of choice for diagnostic and therapeutic use in ED. A recent agent is a mixture of a vasoactive intestinal polypeptide (aviptadil) and phentolamine.
CONCLUSIONS
After 40 years, self-injection therapy represents the medication with the highest efficacy and reliability rates and remains a viable option for many couples with ED. The history of this therapy is rich.

INTRODUCTION
High-flow priapism is rare, uncontrolled arterial inflow, preceded by penile or perineal trauma and arterial-lacunar fistula. There are several ways to treat high-flow priapism, i.e., conservative management, the use of ice packs, mechanical decompression, surgery, and super-selective arterial embolization. Embolization is currently widely accepted in patients who fail from conservative management. This study aimed to report the use of Gelfoam and microcoil embolization in recurrent high-flow priapism compared to PVA embolization.
CASE STUDY
A 36-year-old man complained of prolonged erection. The erection occurred three days before admission while waking up in the morning, not accompanied by either sexual stimulation or pain. There was a history of fall four days ago in the afternoon, with the patient's groin hitting a rocky ground. Physical examination revealed an erect penis, which felt warm, with an EHS of 4. Blood gas analysis of the corpus cavernosum showed bright red blood with a pH of 7.47, pCO of 23.6, pO of 145, HCO of 17.3, BE of -6, and SaO of 99%. Doppler ultrasound examination of the penis showed high-flow priapism. Embolization with PVA was performed, and there were decreased complaints. A few hours later, the erection occurred. Reevaluation was then performed and continued with embolization using Gelfoam and microcoil. There were immediate successful results (EHS of 3) accompanied by a decrease in symptoms. Long-term follow-up has shown a return to normal erectile function six months following the injury.
CONCLUSION
Priapism may happen due to various etiologies. Differentiating high-flow and low-flow is paramount during the acute phase because of different treatment strategies. Conservative management may be applied to high-flow priapism. If conservative management fails, embolization may be attempted. The choice of embolization agent must be taken into account.

Review
BACKGROUND AND OBJECTIVE
We present an overview of the 2024 updates for the European Association of Urology (EAU)/European Society for Paediatric Urology (ESPU) guidelines on paediatric urology to offer evidence-based standards for perioperative management, minimally invasive surgery (MIS), hydrocele, congenital lower urinary tract obstruction (CLUTO), trauma/emergencies, and fertility preservation.
METHODS
A broad literature search was performed for each condition. Recommendations were developed and rated as strong or weak on the basis of the quality of the evidence, the benefit/harm ratio, and potential patient preferences.
KEY FINDINGS AND LIMITATIONS
Recommendations for perioperative management include points related to fasting, premedication, antibiotic prophylaxis, pain control, and thromboprophylaxis in patients requiring general anaesthesia. MIS use is increasing in paediatric urology, with no major differences observed among different MIS approaches. For hydrocele, observation is the initial approach recommended. For persistent cases, treatment varies according to the type of hydrocele. CLUTO cases should be managed in tertiary centres with multidisciplinary expertise in prenatal and postnatal management. Neonatal valve ablation remains the mainstay of treatment, but associated bladder dysfunction requires continuous treatment. Among urological traumas and emergencies, renal trauma is still an important cause of morbidity and mortality. Conservative management has become the standard approach in haemodynamically stable children. Ischaemic priapism is a medical emergency and requires stepwise management. Initial management of nonischaemic priapism is conservative. Fertility preservation in prepubertal children and adolescents has become an increasingly relevant issue owing to the ever-increasing number of cancer survivors receiving gonadotoxic therapies. A major limitation is the scarcity of relevant literature.
CONCLUSIONS AND CLINICAL IMPLICATIONS
This summary of the 2024 EAU/ESPU guidelines provides updated guidance for evidence-based management of some paediatric urological conditions.
PATIENT SUMMARY
We provide a summary of the updated European Association of Urology/European Society for Paediatric Urology guidelines on paediatric urology. There are recommendations on steps to take before and immediately after surgery, management of hydrocele, congenital lower urinary tract obstruction, and urological trauma/emergencies, as well as preservation of fertility. Recommendations are based on a comprehensive review of recent studies.

Review
INTRODUCTION
With 50 years' experience, inflatable penile implants are the preferred option for erectile dysfunction refractory to pharmacological and mechanical treatment. Technical and surgical improvements have optimized patient success and satisfaction. However, multi-factorial dissatisfaction persists.
OBJECTIVE
The aim of this study is to provide an overview of available technological improvements and innovations, as well as the perioperative management and complications of inflatable penile implant surgery.
METHOD
A literature review was carried out over the last twenty years to answer 4 questions: what are the different inflatable penile implants available in 2023, for which indications, results and complications.
RESULTS
Four companies propose inflatable penile implants in France. The main improvements have been in the various components of the prosthesis with better cylinder extension, more ergonomic reservoirs, and more manageable pumps, leading to a better durability. Indications have been extended to patients suffering from Peyronie's disease and in emergency cases of priapism. In response to demand from the transgender population, specific phalloplasty implants have been developed. New options are being developed for difficult cases of retracted penis. Results show a high satisfaction rate. Currently the main challenge is the management of infection with the development of rescue protocols using antibiotics to preserve implants - or replace them in a single operation.
CONCLUSION
After 50years' experience, improvements in penile implants led to effective, satisfactory and safe treatment and can be proposed in new indications. Further development is sill necessary to offer solutions in difficult cases.

Ischemic priapism is a relatively uncommon genitourinary condition that, if left untreated, can lead to permanent erectile dysfunction. Detumescence should ideally be attained within the first 36 h of onset to avoid irreversible fibrosis and necessary surgery. Opportunities to practice medical management of this condition are scarce, and the risk of iatrogenic injury of vessels, nerves, and urethra can be significant if performed blind. Visualizing these structures through ultrasonography can reduce the risk of injury and aid in the confirmation of drug delivery. This novel utilization of ultrasound guidance in active treatment can help improve physician confidence and success in managing this rare and urgent condition. To our knowledge, this is the first report of point-of-care ultrasound-guided penile nerve block used to manage pain associated with priapism. We present a 44-year-old male presenting with a painful erection lasting for eight hours. Penile doppler ultrasound was performed concurrent with medical management of priapism, with successful detumescence and discharge.

INTRODUCTION
The objective of this study was to assess the rates of surgical shunting and prosthesis placement for acute ischemic priapism using a large multi-institutional claims database.
METHODS
A US claims database network (TriNetX Diamond Network) was queried from 2010 to 2020. We constructed a cohort of men ages ≥ 16 years who (1) had a diagnosis of priapism and (2) underwent an irrigation of the corpora cavernosa for priapism. We assessed the number of men who then had a surgical penile shunt or penile prosthesis placement. Demographics, time to surgical procedure, and order of procedures were collected.
RESULTS
A total of 6392 men were identified with the diagnosis of priapism and the procedure of corpora cavernosal irrigation. Of these men, 693 (11%) proceeded to surgical shunt. One hundred forty-four men (2%) underwent initial penile prosthesis placement. Of the men undergoing initial penile prosthesis, only 17 of 144 (12%) cases occurred within the first month of corpora cavernosal irrigation. Finally, when assessing choice of initial shunts vs initial penile prosthesis before and after 2015, overall rates of initial shunt (10.0% vs 8.5%, < .0001) and initial prosthesis (3.1% vs 2.1%, < .0001) were lower after 2015 when compared with rates prior to 2015.
CONCLUSIONS
In this US claims-based analysis of men presenting with ischemic priapism and treated with initial irrigation, a small percentage (11%) of men went on to receive surgical shunting, and only 2% received an initial prosthesis. Men receiving initial prostheses were more likely to have more comorbidities, and overall surgical management of priapism has decreased over time.
