A multi-institutional update on surgical outcomes after penile silicone sleeve implantation.

Background: The increasing popularity of the silicone sleeve penile implant has been accompanied by concerns over potential risks and adverse events. Objectives: To provide multi-institutional data on safety outcomes in patients undergoing silicone sleeve penile implant surgery across high-volume implant surgeons. In addition, we discuss preventative techniques to minimize postoperative complications and the management of these events. Design and methods: We performed a retrospective analysis of men undergoing penile silicone sleeve implants between November 2020 and November 2022 with four surgeons, each from a separate institution. Perioperative and postoperative adverse events, including unsatisfactory cosmetic outcomes requiring revision, were determined by physician follow-up. Flaccid penile length and girth were measured preoperatively and postoperatively. Results: A total of 299 male patients underwent silicone sleeve implant surgery, with an average age of 42.5 ± 10.5 years and an average body mass index of 28.5 ± 4.0. The patient cohort exhibited minimal comorbidities, with 5% having hyperlipidemia, 2% being smokers, 2% having cardiovascular disease, and 1% having diabetes. Patients experienced an average increase of 4.1 ± 1.5 cm in their flaccid penile length (a 50% increase) and an average increase of 3.4 ± 1.5 cm in their flaccid girth (a 37% increase) (p < 0.01). Complication rates included new-onset postoperative erectile dysfunction (0%), infection (1.3%), seroma (2.0%), and erosion (5.0%). The average follow-up time was 11.6 months. Notably, our rates of infection and seroma were lower than those reported in a previous single-center review, while erosion rates were higher. Conclusion: This is the largest study to characterize the safety of the penile silicone sleeve implant across multiple institutions. In men who desire cosmetic size augmentation, silicone sleeve implant surgery is associated with significantly increased flaccid penile length and girth. Complications are mainly cosmetic and may be corrected; however, patients should be appropriately counseled on the risk of erosion, which appears to be higher than previously reported.

Cosmetic penile enhancement procedures: an SMSNA position statement.

BACKGROUND: Penile cosmetic enhancement procedures have been performed for many years with varying success. However, they have historically been relegated to niche areas of sexual medicine, with limited data, and have not achieved mainstream adoption. More recently, the topic has been increasingly discussed within academic congresses due to availability of novel techniques, therapies, and procedures. Given their distinctive nature, the Sexual Medicine Society of North America (SMSNA) felt that it was pertinent to develop formal position statements to help guide both patients and sexual medicine providers on the current state of the scientific literature and to give recommendations for future research. AIM: The study sought to provide an evidence-based set of recommendations for injection and surgical procedures designed to lengthen, augment, or otherwise cosmetically enhance the penis. METHODS: A review was performed of all scientific literature listed in PubMed from inception through December 2023 relating to penile cosmetic enhancement procedures. Only invasive (injection/surgery) therapies were included due to their distinct risk-benefit profile compared with more conservative treatments (eg, vacuum erection devices, penile traction devices). Similar therapies were categorized, with pertinent data summarized and used to help create relevant position statements. All statements were expert opinion only and were based on analyses of the potential risks and benefits of the specific therapies. OUTCOMES: A total of 6 position statements were issued relating to 5 distinct sexual medicine cosmetic enhancement procedures. RESULTS: A consensus opinion was reached by SMSNA leadership on the state of injection/surgical penile cosmetic enhancement procedures as of 2024. Key topic areas addressed included injectable soft tissue fillers, suspensory ligament division, graft-and-flap procedures, silicone sleeve implants, and sliding/slicing techniques. Distinct recommendations were tailored to each therapy and were based solely on the current state of the literature. It is anticipated that future studies will further inform position statements and will lead to ongoing modifications. CLINICAL IMPLICATIONS: The current position statements provide both patients and clinicians evidence-based, expert recommendations on best practices relating to penile cosmetic enhancement procedures. STRENGTHS AND LIMITATIONS: Strengths include the use of an expert panel of sexual medicine clinicians, consensus design, and summary of existing literature. Limitations include expert opinion and limited research on the topic. CONCLUSION: The current SMSNA position statements provide evidence-based, consensus opinions on the appropriate role for penile augmentation and cosmetic procedures in 2024.

For the penile length-how shall we choose the straightening procedures in hypospadias repair?

OBJECTIVE: To define the appropriate penile straightening procedures corresponding to the specific penile curvature by comparing the penile length resulting from various straightening procedures in hypospadias repair. METHODS: We retrospectively analyzed hypospadias patients between 2017 and 2019. Patients were divided into three groups based on the penile curvature after degloving: <30°, 30°-45°, and >45°. The penile straightening procedures include dorsal plication (DP), simple urethral plate (UP) transection, and UP transection with ventral lengthening (VL). The paired t-test was conducted for the penile length after fully straightening in each group, simultaneously calculating the length changes (∆T). In addition, the penile length changes among these procedures were compared using Spearman analysis to show the correlation between the penile curvature and the length. RESULTS: The penile length changed significantly after fully straightening in all groups. The length decreased mildly after DP, while increased in the other procedures. The penile curvature after degloving was positively correlated with the absolute change in the penile length (P < 0.001, r = 0.424) and the ratio of ∆T in the original length (P < 0.001, r = 0.433). CONCLUSION: For hypospadias, the 30° after degloving may serve as the cut-off for the selection of the straightening method from the perspective of the penile length. For those with < 30°, methods such as DP or UP transection can either be selected. In patients with > 30°, DP should be used with caution because of the potential risk to shorten the penis. In contrast, UP transection effectively corrects the penile curvature and increases the penile length concurrently, which should be primarily recommended in those patients.

The effect of penile traction device in men with Peyronie's disease on penile curvature, penile length, and erectile dysfunction: a systematic review and meta-analysis.

Background: Peyronie's disease (PD) results in curvature, pain, and erectile dysfunction (ED). Penile traction devices (PTDs) are a non-invasive treatment option for PD by applying mechanical forces to elicit biochemical responses that reduce curvature and improve penile function. In the present study, we systematically reviewed and analyzed the literature investigating the use of PTD to treat PD. Methods: We have conducted electronic and manual search strategies within the databases and included articles to find relevant studies. A total of Five studies met all the predefined inclusion criteria and were selected for inclusion in the review. Outcomes assessed are penile length, penile curvature, and erectile function (EF). The study population consisted of patients with PD, the intervention was penile traction therapy (PTT), the comparison was matched placebo or follow-up, and the study design was randomized controlled trials (RCTs) or cohort studies. The Cochrane risk of bias assessed the studies' quality for randomized studies and the Newcastle-Ottawa scale (NOS) for non-randomized observational studies. All statistical analyses were performed using R software. Results were considered statistically significant for P<0.05. Results: Only five studies met inclusion and exclusion criteria and were published between 2014 and 2021. The sample sizes range [51-110], totaling 419, with a mean of 83.8 patients-the follow-up with a mean of 6.75 months. This meta-analysis evaluated the efficacy of PTD on curvature degree, penile length, and EF in patients. There is a significant positive effect on the curvature degree (P=0.0373), while there is no significant effect on penile length and EF (P=0.5315 and 0.1010), respectively. They are Indicating low heterogeneity with an estimated total heterogeneity of 0. Overall, the available evidence does not support the efficacy of the intervention for penile length or EF. Conclusions: The current evidence suggests that PTDs can be a safe and effective treatment option for men with PD to reduce penile curvature. However, further research, including more RCTs with extended follow-up periods, is needed to fully understand their efficacy and determine the ideal timing and patient subtypes that would benefit from PTD.

Estimation of Reference Values for External Genitalia Parameters in North Indian Preterm and Term Male Newborns.

OBJECTIVES: To generate gestation-wise normative data of external genitalia measurements in North Indian term and preterm male newborns. METHODS: This was a hospital-based cross-sectional observational study. Male neonates born between 28-42 wk of gestation (at 24-72 h of life) were consecutively recruited in the study. Newborns with major congenital malformations, chromosomal anomalies, multifetal gestation and birth injuries were excluded. Data on various genital measurements were collected [Stretched penile length (SPL), penile width (PW), upper anogenital distance (AGDu), lower anogenital distance (AGDl) and anogenital ratio (AGR)]. RESULTS: Out of 532 newborns, 208 (39.1%) were preterm. Mean (± SD) SPL and PW were 27.9 ± 3.6 mm and 10.6 ± 1.3 mm respectively. The mean values for AGDl, AGDu and AGR were 20.13 ± 4.04 mm, 39.2 ± 5.59 mm, and 0.51 ± 0.07, respectively. SPL less than 21 mm in a term male newborn and 17.5 mm in preterm should be considered micropenis (<2.5 SD) in our population. Gestation-wise percentile charts for SPL, PW, AGDl, AGDu and AGR were generated. CONCLUSIONS: The reference values and percentile charts generated can serve as local normative data for accurate interpretation of genital measurements in North Indian newborns, assessment of ambiguous genitalia and avoiding diagnostic errors.

Climacturia and Penile Length Shortening: Adverse Outcomes following Robot-Assisted Radical Prostatectomy.

Purpose: While erectile dysfunction and urinary incontinence are commonly cited side effects following radical prostatectomy (RP), climacturia and penile length shortening are less explored. The present study seeks to explore the incidence, risk factors, and predictors of recovery associated with climacturia and penile length shortening following robot-assisted radical prostatectomy (RARP). Patients and Methods: From September 2018 to January 2020, 800 patients underwent RARP for primary treatment of localized prostate cancer. A survey was sent to patients following 1-year follow-up assessing outcomes of continence, erectile dysfunction, climacturia, and penile length shortening. Descriptive statistics were utilized to describe incidence and risk factors and logistic regression modeling was used to identify predictors associated with recovery. Results: Of the 800 patients surveyed, 339 (42%) and 369 (46%) patients responded, with 127/339 (37.5%) and 216/369 (58.5%) endorsing climacturia and penile length shortening. In univariate analysis, a lack of bilateral nerve sparing was associated with climacturia; high body mass index (BMI), high prostate weight, lack of nerve-sparing, and high pathologic stage was associated with penile length shortening. In logistic regression modeling, BMI, prostate weight, and p-stage were all significantly correlated with penile length shortening. Recovery from climacturia was associated with a preoperative International Index of Erectile Function-5 score >21. When patients were asked to rank the importance of these outcomes compared to erectile dysfunction and incontinence, <5% of patients ranked either climacturia or penile length shortening as a high priority following RP. Conclusion: While incidence of climacturia and penile length shortening following RP is significant, impact on patient- and partner-related quality of life are low in comparison to risks of erectile dysfunction and urinary incontinence.

The factors that cause penile shortening after plication surgery in patients with congenital penile curvature: [[es]]Los factores causantes del acortamiento de pene después de la cirugía con plicatura en pacientes con incurvación peneana congénita.

OBJECTIVE: Congenital penile curvature is defined as the non-straightness of the penis without any urethral or penile pathology. We aimed to evaluate the factors that cause penile shortening after plication surgery in patients with congenital penile curvature. METHODS: Between November 2010 and December 2020, we retrospectively reviewed patients with CPC undergoing tunica albuginea plication surgery. Before the procedure, patients' age, curvature location and degrees, as well as penile length were recorded. After the treatment, penile lengths were measured and recorded again. Early and late period results were recorded. RESULTS: Plication surgery was performed in 130 patients. The median age was 24 years. Seventy-six patients had ventral curvature, 22 had dorsal curvature, 32 had lateral curvature. Average shortening of penile length in patients with curvature below 30° was: ventral 8-16 mm, dorsal 6-13 mm, lateral 5-12 mm. Patients with curvatures above 30° were: ventral 12-22 mm, dorsal 8-20 mm, lateral 2-12 mm. CONCLUSION: Penile length shortening after plication is inevitable. Curvature degree and direction are factors affecting penile length after surgery. Therefore, patients and relatives should be informed in more detail about this complication.

Micropenis.

Micropenis, i.e., a structurally normal but abnormally small penis is defined as stretched penile length (SPL) 2.5 SD below the mean for age and sexual stage. Several studies worldwide have published country-specific normative data on SPL; an appropriate cutoff for evaluation of micropenis as per international standards would be below 2 cm at birth and below 4 cm after 5 y of age. Testosterone production by fetal testes, its conversion to dihydrotestosterone (DHT) and its action on the androgen receptor is necessary for normal penile development. Hypothalamo-pituitary disorders (gonadotropin or growth hormone deficiencies), genetic syndromes, partial gonadal dysgenesis, testicular regression, disorders of testosterone biosynthesis and action constitute the various etiologies of micropenis. Associated hypospadias, incomplete scrotal fusion, and cryptorchidism are suggestive of disorders of sex development (DSD). Along with basal and human chorionic gonadotropins (HCG)-stimulated gonadotropins, testosterone, DHT, and androstenedione levels, karyotype assessment is equally important. Treatment aims at attaining penile length sufficient enough for urination and to perform sexual function. Hormonal therapy with intramuscular or topical testosterone, topical DHT or recombinant follicle stimulating hormone (FSH) and luteinizing hormone (LH) should be attempted in the neonatal or infancy period. The role of surgery for micropenis is limited and has variable patient satisfaction and complication outcomes. There is a need for long-term studies on the adult SPL achieved following treatment for micropenis in infancy and childhood.

Robot assisted laparoscopic radical prostatectomy with maximal urethral length preservation technique preserves penile length.

Penile shortening is a recognized but neglected side effect of prostate cancer treatment. In this study we explore the effect of maximal urethral length preservation (MULP) technique on penile length preservation after robot assisted laparoscopic prostatectomy (RALP). In an IRB approved study, we prospectively evaluated the stretched flaccid penile length (SFPL) pre and post RALP in subjects with a diagnosis of prostate cancer. The multiparametric MRI (MP-MRI) was utilized for surgical planning if available preoperatively. Repeated measures t-test, linear regression and 2-way ANOVA analyses were performed. A total of 35 subjects underwent RALP. Mean age was 65.8 yr (SD: 5.9), preoperative SFPL was 15.57 cm (SD: 1.66) and postoperative SFPL was 15.41 cm (SD: 1.61) p = 0.68. No change in the postoperative SFPL was recorded among 27 subjects (77.1%) while 5 subjects (14.3%) had 0.5 cm shortening, and 3 subjects (8.6%) had 1 cm shortening. Pathologic stage, preoperative MP-MRI and body mass index (BMI) were significant predictors of postoperative SFPL on linear regression analysis, p = 0.001. Among 26 subjects with pathologic stage 2 disease, no statistical difference was seen in repeated measures t-test between pre and postoperative SFPL, 15.36 vs 15.3 cm, p = 0.08. All subjects were continent by 6 months postoperatively, with no complications. We demonstrate that incorporating MULP technique and preoperative MP-MRI preserves SFPL in subjects undergoing a RALP.

Los factores causantes del acortamiento de pene después de la cirugía con plicatura en pacientes con incurvación peneana congénita / The factors that cause penile shortening after plication surgery in patients with congenital penile curvature

Objetivo La incurvación peneana congénita se define como la incurvación del pene en ausencia de patología uretral o peneana. Nuestro objetivo es evaluar los factores causantes del acortamiento del pene después de la plicatura en pacientes con incurvación peneana congénita. Métodos Entre noviembre de 2010 y diciembre de 2020 revisamos de forma retrospectiva a los pacientes con incurvación peneana congénita que se sometieron a una cirugía mediante técnica de plicatura de la túnica albugínea. Antes del procedimiento, se registró la edad de los pacientes, la ubicación y los grados de la desviación y la longitud del pene. Tras el tratamiento se midió y registró de nuevo la longitud del pene. Se registraron los resultados de los períodos inicial y final. Resultado Se realizó cirugía con plicatura en 130 pacientes. La media de edad era de 24 años. Setenta y seis pacientes tenían incurvación ventral, 22 dorsal y 32 lateral. El acortamiento medio de la longitud del pene en aquellos pacientes con incurvación inferior a 30° fue: ventral 8-16 mm, dorsal 6-13 mm, lateral 5-12 mm. En los pacientes con incurvación superior a 30° fue: ventral 12-22 mm, dorsal 8-20 mm, lateral 2-12 mm. Conclusión El acortamiento del pene después de la plicatura es inevitable. El grado y la dirección de la desviación son factores que afectan la longitud del pene después de la operación. Por lo tanto, los pacientes y sus familiares deben recibir información detallada sobre esta complicación (AU)

Imaging in fetal genital anomalies.

Genital anomalies are a heterogeneous group of congenital pathologies that have become increasingly relevant since the Chicago Consensus of 2005. Their postnatal diagnosis has developed significantly in the last two decades, while prenatal diagnosis seems to be underdeveloped, with few protocols available, fragmented scientific literature, and low diagnostic rates. This review aims to examine the current status of this subspecialty from the perspective of prenatal imaging. Indications for the evaluation of fetal genitalia can be divided into medical and non-medical reasons. Medical reasons include sex-linked disorders, detection of other anomalies, relevant family history, or multiple pregnancy. Non-medical reasons include parental request for sex disclosure. Disclosure of fetal sex may be associated with ethical, legal, and medical issues. The main imaging technology used is 2D ultrasound, although there are other complementary techniques such as 3D, MRI, or Color Doppler. Regarding working methodology, several authors have drawn attention to the lack of standardized protocols and guidelines. Most guidelines tend to limit their recommendations to study indications and ethical issues. Technical proposals, measurements, or working methods have not yet been standardized. Fetal sex determination is usually divided into early and late gestation. Early gestation is based on the sagittal sign. Late gestation is based on direct visualization. There are several measurements to describe male and female genitalia, such as penile length, bilabial diameter, or scrotal diameter. Prenatal diagnosis of genital pathologies presents some particularities such as the wide spectrum of phenotypes, the high frequency of associated deformities, or the time of diagnosis. Some of the most frequent pathologies are ambiguous genitalia, fetal sex discordance, hypospadias, micropenis, clitoromegaly, ovarian cysts, hydro(metro)colpos, and cloacal anomalies. Higher-quality studies and direction from scientific societies through the implementation of clinical guidelines are needed.

Depictions of penises in historical paintings reflect changing perceptions of the ideal penis size.

OBJECTIVES: To investigate alterations in depicted penis size by evaluating nude male paintings from the 15th to 21st centuries. MATERIALS AND METHODS: Nude-male paintings were identified from various art history websites and analysed to determine changes in penis size over time. Two observers organised the paintings according to the century in which they were created and made the calculations. Penile length to ear length (PtEL) or penile length to nose length (PtNL) were calculated to standardise the measurements using professional image analysis software. PtEL was first attempted for all paintings; if PtEL could not be ascertained, then nose length was used instead of the ear, as the nose length is defined as equal to ear length according to the golden ratio. Thus, PtNL was ensured and both ratios were then referred to using a common term: penis depiction ratio (PDR). Further analysis was performed by dividing the paintings into three groups according to the historical development of art: Renaissance Period (1400-1599; 15th-16th centuries), Baroque-Rococo and Impressionism Period (1600-1899; 17th-19th centuries) and Contemporary Art Period (1900-2020; 20th and 21st centuries). RESULTS: Of 232 identified paintings, 72 (31.1%) were excluded because they depicted images of adolescents or an erect penis. The PDR was found to differ significantly between paintings created in different centuries (P < 0.001). Subgroup analysis revealed that paintings from the 21st century demonstrated significantly higher PDRs than paintings from previous centuries (P = 0.001). CONCLUSIONS: In paintings depicting nude males, the size of the penis has gradually increased throughout the past seven centuries, and especially after the 20th century. This observation illustrates the changing sociocultural inputs into male body image and emphasises the need for improved understanding of the sociocultural factors associated with the perception of penis size in men.

Anthropometric Predictors of Appropriate-Sized Plastibell for Neonatal Circumcision.

Background: Using anthropometric parameters to determine the appropriate Plastibell size before circumcision ensures that cumbersome carrying of all the sizes before each procedure is eliminated and also complications reduced. Methods: Male neonates who presented for routine circumcision by Plastibell method were recruited. Collected on a proforma were their age in days, weight in Kg, stretched penile length (SPL) in cm, penile diameter (PD) in cm and the Plastibell size used by the "circumciser". The routine circumcision was carried out for each neonate according to protocol. P value was set at <0.05. Results: There were 231 neonates who had Plastibell circumcision. Their mean age, weight, SPL and PD were 15.6(±5.73) days, 3.7(±0.58) Kg, 3.66 (±0.58) cm and 3.79 (±0.64) cm, respectively. Plastibell size 1.3 is the most used (53.6%). There was a positive correlation between weight, SPL, PD, on one hand and Plastibell size , on the other hand with P-values of <0.001, <0.001 and <0.001 respectively. The weight was a weak determinant for Plastibell sizes 1.1 and 1.3: (OR 7.104; 95% CI 1.108 - 45.559; P = .039) and (OR 2.044; 95% CI 1.054 - 3.963; P = .034) respectively. The SPL is also a weak predictor for Plastibell sizes 1.2 and 1.5: (OR 2.176; 95% CI 1.136 -4.136; P = .019) and (OR .043; 95% CI .072 - .984; P = .047), respectively. Conclusion: The anthropometric parameters correlate well with Plastibell sizes. However, they are not effective in predicting the appropriate sized Plastibell for neonatal circumcision.

Ultrasonographic assessment of testicular volume in Japanese newborn infants.

Purpose : It is essential to determine normative data of testicular size and penile length in newborn infants in order to assess the development during the fetal period. In this study, we evaluated testicular volumes using ultrasonography and also measured penile lengths in Japanese newborn infants. We also examined the associations of the development of these organs with factors including placental weight and anthropometric data. Methods : One hundred and fifteen full-term male newborn infants were recruited for this study. Testicular size was measured by ultrasonography. Results : Mean testicular volumes were 187.4 mm3 in the right testis and 185.4 mm3 in the left testis, and there was no significant difference between the right and left testicular volumes. Right and left testicular volumes showed positive and significant correlations with body lengths and weights. Testicular volumes in the right and left sides were not significantly associated with penile lengths. In 4 groups according to gestational weeks, testicular volume increased significantly with advance of gestational weeks in the left testis. Conclusion : We determined testicular volumes using ultrasonography in Japanese newborn infants. We believe that the results for newborn infants provide important information for assessment of the development of fetal testicular volume. J. Med. Invest. 69 : 256-260, August, 2022.

Penile size in term newborns in Addis Ababa, Ethiopia.

AIM: To determine the normative value of stretched penile length (SPL) for Ethiopian newborns and to set a cut-off point for micropenis. METHODS: A total of 221 term newborns were included in the study. Stretched penile length was measured in the first 72 h of postnatal age in neonates with a gestational age of 37-42 completed weeks. SPL < -2 SD was taken as micropenis in this study. RESULTS: The minimum and maximum penile length were 2.5 cm and 5 cm, respectively, with a mean ± SD of 3.28 ± 0.42. SPL at -2 SD and +2 SD were 2.43 and 4.12 cm respectively. A significant correlation was observed between penile length and body length (p = 0.005). Neonates born via instrumental delivery had larger SPL compared to those who were delivered by caesarean section (p = 0.01) or by vaginal delivery (p = 0.006). CONCLUSION: The mean stretched penile length in our study mirrors findings from other African studies. SPL < 2.43 cm can be considered as micropenis in our setting. Therefore, routine genital examination and interpretation at birth is crucial to identify micropenis which might herald a serious underlying condition that needs further investigation.

[Effect of surgical steps in primary hypospadias repair on penile length].

OBJECTIVE: To document the effect of surgical steps, including penile degloving, plate transection, dorsal plication, and fasciocutaneous coverage, in primary hypospadias repair on penile length. METHODS: A consecutive series of 209 prepubertal boys with primary hypospadias repair was included with the age ranged from 10 to 97 months (mean, 31.7 months). Intraoperative stretched penile length (SPL) was measured before operation ( n=209), and after each step, namely penile degloving ( n=152), plate transection ( n=139), dorsal plication ( n=170), and fasciocutaneous coverage ( n=209). SPLs before and after each steps or the entire operation were analyzed. The SPL was compared between plate transection group and plate preservation group, dorsal plication group and non-plication group, and plate preservation with plication group and plate preservation without plication group, respectively. Differences of SPL between before and after each steps were analyzed with factors including neourethra length, rest dorsal penile length, rest ventral penile length, preoperative SPL, and the degree of penile curvature after penile degloving, with multivariate linear regression analysis. RESULTS: All the four steps resulted in SPL difference. The SPL increased after penile degloving and plate transection ( P<0.05), and decreased after dorsal plication and fasciocutaneous coverage ( P<0.05). The SPL increased after all steps were completed ( P<0.05). In patients with plate transection, postoperative SPL increased when compared with that before operation ( P<0.05). No significant difference was noted in patients without plate transection ( P>0.05). And there was significant difference in the increased length of SPL between patients with and without plate transection ( P<0.05). In patients with dorsal plication, a significant increase of postoperative SPL ( P<0.05) was noted. No significant difference was noted in patients without dorsal plication ( P>0.05). And there was no significant difference in increased length between patients with and without dorsal plication ( P>0.05). When patients with plate transection were excluded, dorsal plication resulted in no significant difference on postoperative SPL ( P>0.05). The increased length of SPL after penile degloving, dorsal plication, or cutanofascial coverage was not related to the neourethra length, the rest dorsal penile length, the rest ventral penile length, the preoperative SPL, and the degree of penile curvature ( P>0.05). However, the neourethra length and preoperative SPL were the influencing factors for the increased length of SPL after plate transection ( P<0.05). CONCLUSION: The main steps in primary hypospadias repair can change SPL. The lengthening effect of plate transection would not be counteracted by dorsal plication. Dorsal plication makes no significant difference on postoperative SPL.

A prospective randomized controlled study on scheduled PDE5i and vacuum erectile devices in the treatment of erectile dysfunction after nerve sparing prostatectomy.

Cavernous nerve injury is an important cause of erectile dysfunction (ED). Although protective nerve technology has been widely used in nerve-sparing radical prostatectomy (nsRP), the incidence of ED is still very high after surgery. The purpose of our study was to evaluate erectile function (EF) and penile length in the non-erectile state (PLNES) following scheduled phosphodiesterase 5 inhibitor (PDE5i), vacuum erectile device (VED) treatment, and combination therapy after nsRP. One hundred patients with localized prostate cancer and normal EF were randomized to scheduled PDE5i group, VED treatment group, a combined treatment group, and the control group without any intervention. The International Index of Erectile Function-5 (IIEF-5) scores and PLNES were evaluated after 6 months and 12 months of treatment. Sexual Encounter Profile (SEP-Question 2 and SEP-Question 3) were evaluated after 12 months of treatment. Ninety-one of the 100 randomized patients completed the study. We found that the 5 mg tadalafil once a day (OaD) combined with VED can help improve IIEF-5 scores in nsRP patients after both 6 months and 12 months. VED alone or combined with tadalafil OaD can help patients maintain PLNES. VED combined with tadalafil OaD can improve the rate of successful penetration (SEP-Question 2) after 12 months. There were no significant differences in the return to target EF after 12 months among the groups. No significant correlation was noted between the variables and return to target EF (IIEF ≥ 17), and between the variables and effective shortening of the patient's penis (shortening ≥ 1 cm) after 12 months of intervention.

Reference values for penile and clitoral lengths of healthy term Egyptian newborn infants.

AIM: Examination of the external genital organs is an integral part of the routine physical examination of the newborn. Early recognition of micropenis or clitoromegaly is important as they may be the only obvious manifestation of pituitary or hypothalamic hormonal deficiencies at birth. Studies suggest that differences in penile or clitoral anthropometry may exist between different populations. Therefore, reference values for genital organs dimensions should be available and well known to medical personnel. We aim to establish reference values for the penile length in Egyptian newborn boys and reference values for the clitoral length in Egyptian newborn girls and to define micropenis and clitoromegaly according to Egyptian reference values. METHODS: A total of 500 healthy term newborn boys and 500 healthy term newborn girls were enrolled in the study. Stretched penile length and clitoral length were measured during the first 7 days of postnatal life. Birth weight, length and head circumference were measured and recorded. RESULTS: The mean (±SD) stretched penile length was 3.16 ± 0.41 cm. The mean (±SD) clitoral length was 0.51 ± 0.13. There was no significant correlation between penile or clitoral length, and body weight, length or head circumference. CONCLUSION: Our study provides reference values for normal penile length and clitoral length in Egyptian newborns. Our study suggests that among healthy term Egyptian newborns, penile length of less than 2.13 cm may be considered micropenis and clitoral length of more than 0.83 cm may be considered clitoromegaly.

ESSM Position Statement on Surgical Treatment of Peyronie's Disease.

INTRODUCTION: Patients with Peyronie's disease may experience significat distress. The choice of treatment depends on a variety of factors, including the stage of the disease, the presence of pain, severity and direction of the curvature, penile length and the quality of erectile function. AIM: To review the evidence associated with surgical treatment of Peyronie`s Disease and provide clinical recommendations on behalf of the European Society for Sexual Medicine. 131 peer-reviewed studies and systematic reviews, which were published from 2009 to 2019 in the English language, were included. METHODS: MEDLINE, Google Scholar and EMBASE were searched for randomized clinical trials, meta-analyses, open-label prospective and retrospective studies. MAIN OUTCOME MEASURE: The panel provided statements on clinically relevant questions including patient involvement in the decision process, indications for surgery, choice of the approach, and the management of patient expectations. A comparison of the different grafts used in patients who have undergone plaque incision/excision and grafting in order to identify an ideal graft, has been carried out. The prevalence of postoperative complications has been summarized. Levels of evidence were provided according to the Oxford 2011 criteria and Oxford Centre for Evidence-Based Medicine recommendations. RESULTS: In order to allow shared decision making, a patient preoperative counselling regarding the pros and cons of each intervention is recommended. In particular, adverse effects of surgical treatments should be discussed to set realistic understanding and expectations of surgical outcomes and ultimately improve postoperative satisfaction rates. Surgical treatment should be only offered in the chronic phase of the condition, when the deformity and/or degree of erectile dysfunction, prevent patients from engaging in satisfying sexual interaction, or if the deformity is the cause of severe bother. CONCLUSIONS: Current European Society for Sexual Medicine recommendations cover several aspects of Peyronie's disease treatment. These recommendations aim both to ensure patients and partners have accurate and realistic expectations of their treatment options, as well as to formulate algorithms to guide clinician management pathways.
