BACKGROUND
Penile Doppler ultrasound (PDU) is suggested to be an alternative to blood gas analysis (BGA) from the corpora cavernosa in differentiating between high- and low-flow priapisms, with limited supportive evidence.
AIM
To compare penile Doppler ultrasound study and blood gas analysis in the diagnosis of priapism, through a systematic review of the literature.
METHODS
Studies were identified by literature search of Medline, Scopus, Cochrane and ClinicalTrials.Gov. Studies were included if their participants had priapism evaluated by Penile Doppler ultrasound, and reported data on the blood gas analysis or pudendal artery angiography (PAA). Two authors independently extracted the articles using predetermined datasets, including indicators of quality.
OUTCOMES
Correlation of penile Doppler ultrasound with blood gas analysis and pudendal artery angiography.
RESULTS
Twelve studies were included. Three studies compared Penile Doppler ultrasound to blood gas analysis and pudendal artery angiography. Penile Doppler ultrasound was used as adjunctive to blood gas analysis to differentiate low flow from high flow priapism, guidance for embolization, etiological diagnosis in three studies. Compared to pudendal artery angiography, penile Doppler ultrasound had a sensitivity of 40-100% and a specificity of 73%, to localize vascular injury and anatomical abnormalities (two studies). Penile Doppler ultrasound was also used for the follow-up after the treatment of priapism (two studies). No study reported an impact on functional results or a delay of management due to penile Doppler ultrasound use.
CLINICAL TRANSLATION
We reviewed evidence on penile Doppler ultrasound study in priapism. Penile Doppler ultrasound study performance was comparable to blood gas from corpus cavernosum. It is recommended to use doppler as an alternative diagnostic tool.
STRENGTHS & LIMITATIONS
Our systematic review had limitations. Firstly, the number of cases in the included studies was small. Secondly, these studies were all retrospective. Lastly, few data were reported with regards to hemodynamic parameters of penile Doppler ultrasound, and the majority of studies did not describe these in detail.
CONCLUSIONS
Evidence supports that penile Doppler ultrasound is a reliable way for differentiating high-flow and low-flow priapism. We recommend penile Doppler ultrasound study as an alternative of blood gas analysis from corpus cavernosum, especially when the latter is not available.

Review
Penile intraepithelial neoplasia (PeIN) is a rare skin condition with potential to progress to invasive penile cancer. We performed a systematic review of treatment options and outcomes for PeIN. Topical agents showed response and recurrence rates of 40-100% and 20% for imiquimod, and 48-74% and 11% for 5-fluorouracil, respectively. Discontinuation of topical agents because of side effects was observed in 12% of cases. Response rates for laser therapies were 52-100%, with recurrence in 7-48% of cases and a change in penile sensitivity in 50%. Circumcision cleared preputial PeIN. Rates of recurrence after surgical treatment of glans PeIN were 25% for wide local excision, 4% for Mohs surgery, 5% for total glans resurfacing, and 10% for glansectomy. There are limited data on factors predictive of treatment response and on sequencing of treatment options. PATIENT SUMMARY: Several treatment options are available for men with precancerous lesions of the foreskin or glans. Close follow-up is necessary as lesions can recur or progress to invasive penile cancer.

World Journal of Urology Nov 2023To perform a systematic review of case reports and case series to investigate risk factors, treatment modalities, and the outcome of penile calciphylaxis.
PURPOSE
To perform a systematic review of case reports and case series to investigate risk factors, treatment modalities, and the outcome of penile calciphylaxis.
METHOD
We performed a systematic search of the MEDLINE and Scopus databases to identify case reports or case series of penile calciphylaxis. The patient characteristics, laboratory investigations, diagnostic modalities, treatment modalities, and outcomes were extracted. We compared clinical characteristics and treatment between patients who survived or demised and between patients with clinical improvement and those without to identify the poor prognostic risk factors.
RESULTS
Ninety-four articles were included from 86 case reports and 8 case series with 121 patients. Most of the patients were on hemodialysis (78.9%). The median time since starting dialysis was 48 months (24-96 months). Sodium thiosulfate was used to treat penile calciphylaxis in 23.6%. For surgical management, partial or total penectomy was performed in 45.5% of the patients. There was no association between sodium thiosulfate use, partial or total penectomy, and improvement in clinical outcomes. The mortality rate in patients with penile calciphylaxis was 47.8% and the median time to death was 3 months (0.75-9 months). The presence of extragenital involvement was significantly related to mortality (p = 0.03).
CONCLUSION
A calcified penile artery results in penile calciphylaxis, a rare vascular phenomenon associated with high morbidity and mortality. Management of penile calciphylaxis includes the medical management of risk factors, surgical debridement, or penectomy. Therefore, early prevention and diagnosis as well as immediate appropriate treatment are needed.

Review
INTRODUCTION
Erectile Dysfunction (ED) and Peyronie's Disease (PD) are debilitating medical conditions affecting patients' quality of life (QoL). Platelet-rich plasma (PRP) injections are one of the various emerging approaches proposed to treat these medical conditions.
AIM
To describe the evidence of the potential role of PRP injections in ED and PD.
METHODS
The authors conducted a systematic review according to the PRISMA statement using the following databases in November 2019: The National Library of Medicine (PubMed), Ovid Medline, Cochrane, Scopus, Embase, and Embase classic. The search was performed using keywords drawn from studies on the use of PRP in ED and PD in clinical and preclinical studies.
RESULTS
Eighteen articles met the inclusion criteria for review, including 12 studies on the use of PRP in humans and 6 on the use of PRP in rats. Ten studies reported on the efficacy of PRP in ED exclusively, 7 in PD exclusively and one in both conditions. In humans, 6 and 3 studies showed promising results in PD and ED, respectively. No major complications were noted. Unwanted minor side effects were noted by studies reporting on PD, including mild penile bruising, ecchymosis, hematomas as well as transient hypotension noted in 2 out of 90 patients.
CONCLUSION
PRP injections for the treatment of ED may be promising, but no recommendation can be made because of scarce evidence. Safety and effectiveness of this therapy in the treatment of ED and PD require further preclinical and clinical studies with standardized protocols to gain an adequate insight into its potential implications. Patients should be offered to be part of such trials to better understand PRP potential.

PURPOSE
The interplay between physical and mental aspects of a cancer diagnosis are well recognised. However, little consensus exists on the impact of depression and anxiety on urological cancer outcomes. Therefore, this systematic review aimed to investigate the relationship between these conditions and functional or oncological outcomes in urological malignancy.
MATERIALS AND METHODS
A systematic search was conducted using PubMed, Embase, PsycINFO and Global Health databases up to June 2020. Studies evaluating the relationship of anxiety and depression disorders or symptoms on functional and mortality outcomes were included. Outcome measures included validated urinary, sexual, body image questionnaire scores and all-cause or disease-specific mortality.
RESULTS
Of 3,966 studies screened, 25 studies with a total of 175,047 urological cancer patients were included. Significant anxiety and depressive symptoms and disorders were found to impact functional outcomes in several cancer types. A consistent negative association existed for sexual function in prostate, testicular and penile cancer patients. Additionally, poorer urinary function scores were seen in prostate cancer, with increased body image issues in testicular and prostate cancer. Importantly, both overall and disease-specific mortality outcomes were poorer in bladder and prostate cancer patients.
CONCLUSIONS
Co-existing depression and anxiety appears to be negatively associated with functional and mortality outcomes in urological cancers. This appears especially evident in male cancers, including prostate and testicular cancer. Although not proving causation, these findings highlight the importance of considering mental wellbeing during follow-up for early recognition and treatment. However, current evidence remains heterogenous, with further studies required exploring patients at risk.

INTRODUCTION
Evidence for noninvasive management of Peyronie's disease contains many options with varying levels of evidence for each. Many first-line treatments recommended by urologists lack strong evidence for their use.
AIM
We summarize the noninvasive (oral medications, topical medications, traction, vacuum erection devices, extracorporeal shock wave therapy, intracavernosal injections and electromotive therapy) treatment options for Peyronie's disease and provide the levels of evidence for each.
METHODS
A literature search of PubMed, EMBASE, Cochrane Library, and ClinicalKey databases was conducted, current up to April 2019.
MAIN OUTCOME MEASURE
For each treatment modality, we measured level of evidence, change in penile curvature, change in erectile function, the percentage of patients with improved angulation, and pain scores.
RESULTS
There is weak evidence to support the use of oral or topical medications. Higher levels of evidence exist for intracavernosal injections and extracorporeal shock wave therapy and may be helpful in certain patient populations.
CONCLUSION
The mechanisms behind Peyronie's disease are not fully understood. Penile injections provide the highest quality of evidence for noninvasive treatment. Ory J, MacDonald L, Langille G. Noninvasive Treatment Options for Peyronie's Disease. Sex Med Rev 2020;8:603-614.

Meta-Analysis
BACKGROUND
Hyaluronic acid is a glycosaminoglycan widely used in the fields of orthopedics, ophthalmology, and aesthetic medicine due to its significant ability to reduce the synthesis of pro-inflammatory proteins and its activity against oxidative stress, a feature of many degenerative illnesses.
OBJECTIVES
The objective of the present review is to provide a comprehensive narrative review of the most recent literature on the use of hyaluronic acid in andrology in order to facilitate the use of this therapeutic device in the common clinical practice of many physicians. Specific conditions covered in the review are Peyronie's disease, premature ejaculation, and penile enlargement.
MATERIALS AND METHODS
A broad and comprehensive literature search included Medline, EMBASE, and the Cochrane Libraries, with no time restriction up to December 2020 and restricted to English language publications. Unpublished studies were not included. The study was registered as "The role of hyaluronic acid in andrology: A systematic review and meta-analysis" in PROSPERO with the ID CRD42021223416.
DISCUSSION AND CONCLUSION
Hyaluronic acid is a valid choice for the treatment of Peyronie's disease in terms of the resolution of the acute phase of the disease and of contributing to stabilizing the disease as a bridge to potential surgery. Data, furthermore, suggest that hyaluronic acid is frequently associated with an overall clinical improvement, allowing the patient to resume normal sexual activity. With regard to premature ejaculation, data suggests hyaluronic acid-based treatments were effective in prolonging intra-vaginal ejaculation time. Furthermore, hyaluronic acid was found to be safe and well-tolerated, with main adverse events limited to local discomfort, ecchymosis, papule formation, and glans numbness, all of which were reported to resolve spontaneously. Last, with regard to penile enlargement, the overall perception of experts is that hyaluronic acid may be an extremely well-tolerated compound with potential for application in specific areas of male sexual health that are often neglected as compared to more common, and relatively simpler to treat, conditions.

Review
INTRODUCTION
Penile prosthesis (PP) implantation combined with grafting techniques is indicated in patients with Peyronie's disease (PD) and erectile dysfunction (ED) nonresponsive to medical and conservative treatment that present with residual penile curvature greater than 30°, severe penile deformity or significant penile shortening.
OBJECTIVES
To address the preoperative evaluation, the surgical procedure and the functional outcomes of grafting techniques combined with PP implantation in patients with PD and concomitant ED and to provide future perspectives on the matter.
METHODS
We performed a systematic review of the literature based on the PRISMA statement (PROSPERO ID: CRD42021224517). Records were identified by searching Medline, Scopus, The Cochrane Library and Web of Science databases as well as sources of gray literature from inception to December 2020. The quality of all included records was assessed based on a modified version of the Newcastle-Ottawa Scale for cohort studies.
RESULTS
A total of 935 patients with a mean age of 59.6 ± 9.2 years from 23 studies were included in this systematic review. All studies reported excellent short- and long-term postoperative results, as well as high satisfaction rates ranging from 80 to 100%. A mean increase of 2.7 ± 1.4 cm in penile length was observed. Among different grafting materials and different types of PP, no significant differences in terms of preoperative, perioperative and postoperative functional outcomes or complications were demonstrated. Still, the operative time was shorter in studies applying the collagen fleece TachoSil.
CONCLUSIONS
PP implantation combined with grafting is a safe and highly effective surgical procedure in patients with PD and concomitant ED. All grafting materials provide similar beneficial outcomes, but TachoSil subsequently reduces the operative time and does not require suturing. Still, no definite conclusions can be drawn regarding the superiority of one grafting technique over the other, as randomized clinical trials are lacking.

Meta-Analysis
BACKGROUND
Men who have sex with men (MSM) are disproportionately affected by HIV and other sexually transmitted infections (STIs) worldwide. Previous reviews investigating the role of circumcision in preventing HIV and other STIs among MSM were inconclusive. Many new studies have emerged in the past decade. To inform global prevention strategies for HIV and other STIs among MSM, we reviewed all available evidence on the associations between circumcision and HIV and other STIs among MSM.
METHODS
In this systematic review and meta-analysis, we searched PubMed, Web of Science, BioMed Central, Scopus, ResearchGate, Cochrane Library, Embase, PsycINFO, Google Scholar, and websites of international HIV and STI conferences for studies published before March 8, 2018. Interventional or observational studies containing original quantitative data describing associations between circumcision and incident or prevalent infection of HIV and other STIs among MSM were included. Studies were excluded if MSM could not be distinguished from men who have sex with women only. We calculated pooled odds ratios (ORs) and their 95% CIs using random-effect models. We assessed risk of bias using the Newcastle-Ottawa scale.
FINDINGS
We identified 62 observational studies including 119 248 MSM. Circumcision was associated with 23% reduced odds of HIV infection among MSM overall (OR 0·77, 95% CI 0·67-0·89; number of estimates [k]=45; heterogeneity I=77%). Circumcision was protective against HIV infection among MSM in countries of low and middle income (0·58, 0·41-0·83; k=23; I=77%) but not among MSM in high-income countries (0·99, 0·90-1·09; k=20; I=40%). Circumcision was associated with reduced odds of herpes simplex virus (HSV) infection among MSM overall (0·84, 0·75-0·95; k=5; I=0%) and penile human papillomavirus (HPV) infection among HIV-infected MSM (0·71, 0·51-0·99; k=3; I=0%).
INTERPRETATION
We found evidence that circumcision is likely to protect MSM from HIV infection, particularly in countries of low and middle income. Circumcision might also protect MSM from HSV and penile HPV infection. MSM should be included in campaigns promoting circumcision among men in countries of low and middle income. In view of the substantial proportion of MSM in countries of low and middle income who also have sex with women, well designed longitudinal studies differentiating MSM only and bisexual men are needed to clarify the effect of circumcision on male-to-male transmission of HIV and other STIs.

Meta-Analysis
BACKGROUND
The therapeutic role of extracorporeal shockwave therapy (ESWT) for Peyronie's disease (PD) has been controversial in a long term. We aimed to further evaluate the therapeutic effect of ESWT for PD on the basis of available high-quality studies.
METHODS
The PubMed, CENTRAL and Embase databases were searched for articles published from January 1st, 2000 to December 31, 2022. Only randomized controlled trials (RCTs) using ESWT to treat PD were included. Meta-analysis and forest plots were carried out using Review Manager 5.4.1 software, and outcomes were reviewed by 2 authors independently. Using the Risk of Bias assessment form (ROB-2) by Cochrane Collaboration for quality assessment. PRISMA 2020 guidelines were used in this article to achieve the quantitative and qualitative synthesis of data.
RESULTS
A total of four RCTs were included. 151 patients in the ESWT group and 150 patients in the control group. The meta-analysis results showed that ESWT could significantly reduce plaque size (OR 2.59, 95%CI 1.15 to 5.85, P = 0.02) and relieve pain (MD -1.55, 95%CI -2.46 to -0.64, P = 0.0008); but it has no significant effect on reducing the penile curvature (OR 1.93, 95%CI 0.87-4.26, P = 0.11) and improving sexual function (MD 2.6, 95%CI -1.63 to 6.83, P = 0.23), there is also no significant difference in complication rates between groups (OR 2.94, 95%CI 0.66 to 13.03, P = 0.16). The risk of bias of results is low. The limitations of this study are that the number of included studies is too small, some experimental outcomes are missing, and the expression of outcomes is not unified.
CONCLUSIONS
For PD, ESWT can be considered as a safe short-term treatment, which can reduce plaque size and relieve pain, but cannot improve penile curvature and sexual function. Its long-term efficacy remains to be discussed.
