ABSTRACT

A ultrassonografia é um exame complementar não invasivo ainda pouco utilizado na avaliação prepucial e sem descrições detalhadas da parte livre do pênis (PLP) de bovinos. Este estudo objetivou padronizar a ultrassonografia prepucial em bovinos hígidos da raça Nelore com um ano de idade e, para tanto, descreveu o aspecto da lâmina interna prepucial (LIP) e da PLP, determinando as principais janelas acústicas, a viabilidade da utilização de contraste no lúmen da cavidade prepucial (LCP) e o melhor posicionamento do animal para a realização do exame. O escaneamento foi realizado com os animais na posição quadrupedal e em decúbito lateral direito. Foram determinadas cinco janelas acústicas a partir do óstio até a identificação do recesso prepucial. Os escaneamentos foram realizados nos planos longitudinais, transversais e dorsais, antes e após a infiltração de solução fisiológica a 0,9% no LCP. Como conclusões, o exame ultrassonográfico permitiu identificar a LIP e a PLP em todos os planos e em todas as janelas acústicas propostas. O melhor ponto de referência é a identificação da glande. O posicionamento quadrupedal é mais adequado para a realização do exame e o uso de contraste é recomendado para delimitação topográfica das estruturas.(AU)


Ultrasonography is a noninvasive complementary exam that is still rarely used in the preputial evaluation and without detailed descriptions of the bovine free end of the penis. The purpose of this study was to standardize preputial ultrasonography in one-year-old healthy Nelore cattle, describing the main acoustic windows, the viability of using contrast in the preputial cavity and the best positioning of the animal for performing the ultrasound examination. The scanning was performed with the animals in standing and decubitus position. Five acoustic windows were determined from the preputial ostium to the preputial fornix, at the free end of the penis. The scans were performed in longitudinal, transverse and dorsal planes, before and after infiltration of 0.9% saline solution into the preputial cavity. As conclusions, the ultrasound examination is able to identify the internal layer and the free part of the penis in all proposed planes and acoustic windows. The best landmark is the identification of the glans. Furthermore, standing positioning is the most appropriate to perform the exam and the use of contrast is recommended for topographic delimitation of the structures.(AU)

ABSTRACT

El término pene no conspicuo (oculto), agrupa las patologías en las que el pene adopta un tamaño aparentemente más pequeño, ya sea porque se oculta bajo el tejido cicatricial en caso del pene atrapado, cuando presenta un pliegue de piel que reduce el ángulo penoescrotal tratándose del pene en vela, o en los casos en los que el pene es cubierto por prepucio redundante produciendo un pene enterrado. Se realiza una revisión de la definición y terminología utilizada a través de la historia, clasificación actual, etiología, diagnóstico y técnica quirúrgica empleada para la corrección del pene no conspicuo (oculto).


Inconspicuous penis is referred conditions where the penis looks apparently small but is truely hidden under scarring tissue or under redundant mucosa or prepubic fat. These are all different pathologies that are surgically treated. Multiple techniques have been described. The aim of the present article is to review the state of the art in management throughout history, current classification, etiology, diagnosis and surgical techniques for correcting this pathology.

ABSTRACT

The risk-benefit profile of neonatal circumcision is not clear. Most studies have focused on urinary tract infections but other health sequelae have not been evaluated. While evidence supports benefits of circumcision, a lack of randomized trials has been cited as a weakness. National guidelines provide mixed recommendations regarding neonatal circumcision. We review the weight of evidence and utilize current statistical methodology on observational data to examine the risks and benefits of neonatal circumcision.

ABSTRACT

<p><b>Objective</b>To investigate the clinical effects of circumcision by surgical plane positioning with a disposable circumcision suture device in the treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>From September 2016 to June 2017, we treated 250 patients with phimosis or redundant prepuce, 127 by conventional circumcision (the control group) and the other 123 by surgical plane positioning with a disposable circumcision suture device (the observation group). We compared the operation time, intra-operative bleeding, preputial frenulum alignment, postoperative ecchymosis, and postoperative penile appearance between the two groups of patients.</p><p><b>RESULTS</b>Compared with the controls, the patients in the observation group showed significantly longer operation time ([4.48 ± 1.18] vs [7.17 ± 1.42] min, P<0.05), lower rates of intra-operative frenulum bleeding (15.0% [19/127] vs 4.1% [5/123], P<0.05) and frenulum misalignment (26.8% [34/127] vs 0.8% [1/123], P<0.05), higher incidence of postoperative ecchymosis (41.7% [53/127] vs 21.1% [26/123], P<0.05), and higher satisfaction of the patients with the postoperative penile appearance (92.9% [18/127] vs 98.4% [121/123], P<0.05). However, no statistically significant difference was found between the control and observation groups in intra-operative non-frenulum bleeding (4.7% [6/127] vs 1.6% [2/123], P = 0.164).</p><p><b>CONCLUSIONS</b>Circumcision by surgical plane positioning with a disposable circumcision suture device can effectively avoid preputial frenulum misalignment, reduce intra-operative bleeding, and improve postoperative penile appearance.</p>

ABSTRACT

<p><b>Objective</b>Human papilloma virus (HPV) is a necessary cause of cervical cancer and is also closely related to penile cancer, oropharyngeal cancer, and anal cancer in males. However, few studies are reported on male HPV. This study aimed to investigate HPV infection of the external genitalia in men whose female partners have cervical HPV infection.</p><p><b>METHODS</b>We collected the relevant data on the male outpatients whose partners had cervical HPV infection in our Department of Urology and Andrology from August to December 2016. We obtained samples with nylon swabs from the glans penis, corona, inner layer of the prepuce and penile body and detected different types of HPV infection using the Hybribio HPV typing kit, PCR and membrane hybridization.</p><p><b>RESULTS</b>Valid data were collected from 140 males, which showed 83.5% of HPV infection of the external genitalia, including 60 cases of HPV6 (43.2%), 27 cases of HPV16 (19.4%), 14 cases of HPV39 (10.1%), 13 cases of HPV18 (9.4%), 13 cases of HPV58 (9.4%), and 13 cases of HPV52 (9.4%). Redundant prepuce was found in 75.5% of the males, but there was no statistically significant difference in the incidence rate of HPV infection between the normal and redundant prepuce groups (P > 0.05).</p><p><b>CONCLUSIONS</b>Men who have the female partners with positive cervical HPV are at high risk of HPV infection and therefore need to be screened and treated so as to reduce HPV infection in both sexes.</p>

ABSTRACT

A acropostite-fimose é um processo inflamatório da extremidade do prepúcio, diagnosticada com frequência em touros. O presente estudo objetivou avaliar o exame ultrassonográfico na definição da viabilidade do folheto prepucial interno (FPI) e na evolução clínica do pós-operatório, após o emprego de fios de categute ou poliglactina na hemostasia e de algodão ou poliglactina na confecção de sutura padrão Donatti empregada para fixar o FPI à pele prepucial no transoperatório da acropostite-fimose em touros. A sutura utilizada foi captonada ou não captonada, e os animais submetidos ao procedimento cirúrgico apresentavam no mínimo dois terços do FPI viável. Os touros foram alocados, aleatoriamente, em quatro grupos contendo nove animais cada, de acordo com o fio empregado na hemostasia e na confecção da sutura padrão Donatti. O exame ultrassonográfico mostrou-se importante na indicação ou não do tratamento cirúrgico da acropostite-fimose e possibilitou localizar lesões, mensurar a área de reação tecidual e identificar lesões profundas e pontos de estreitamento do FPI. Os animais de GII apresentaram edema mais discreto, observando-se diferença significativa (P<0,05) entre GII e os grupos GI, GIII e GIV. A ocorrência de hiperemia no sétimo dia de pós-operatório também foi menor nos touros do grupo GII, ocorrendo diferença significativa (P<0,05) entre GII e os grupos GI e GIII. A sutura empregando o dispositivo de látex (cápton) e o emprego do fio de poliglactina apresentaram-se como medidas benéficas, resultando em menor número de complicações pós-operatórias.(AU)


Acropostitis-Phimosis is an inflammatory process of the extremity of the prepuce, frequently diagnosed in bulls. The present study aimed to evaluate ultrassound exams in the definition of viability of the internal layer of prepuce and the postoperative clinical evolution. This evaluation is after the employment of catgut or poliglactin threads in homeostasis, and cloth or polyglactin threads in confection of the standard suture, Donatti, used to fix the internal layer of prepuce to the preputial in the postoperative of acropostitis-phimosis in bulls. The suture was captonated and non-captonated and the animals conducted to the surgical procedure showed at least 2/3 of viability of the internal layer of prepuce. The bulls were randomly allocated in four groups, each one containing nine animals, according to the thread used in homeostasis and confection of the Donatti standard suture. Ultrassound was shown to be important in the indication or not of the surgical treatment of acropostitis-phimosis and allowed the identification of lesions, measurement of areas of tissue reaction and locate deep lesions and narrowing points of internal layer of prepuce. The employment of latex device (capton) in suture and the employment of polyglactin thread 910 were shown as beneficial measures, resulting in a lower number of postoperative complications.(AU)

ABSTRACT

A paraffinoma is a type of inflammatory lipogranuloma that develops after the injection of an artificial mineral oil, such as paraffin or silicon, into the foreskin or the subcutaneous tissue of the penis for the purpose of penis enlargement, cosmetics, or prosthesis. The authors experienced a case of macro-paraffinoma associated with sexual dysfunction, voiding dysfunction, and pain caused by a buried glans penis after a paraffin injection for penis enlargement that had been performed 35 years previously. Herein, this case is presented with a literature review.

ABSTRACT

In spite of frequent usage of primary human foreskin keratinocytes (HFKs) in the study of skin biology, senescence-induced blockage of in vitro proliferation has been a big hurdle for their effective utilization. In order to overcome this passage limitation, we first isolated ten HFK lines from circumcision patients and successfully immortalized four of them via a retroviral transduction of high-risk human papillomavirus (HPV) E6 and E7 oncogenes. We confirmed expression of a keratinocyte marker protein, keratin 14 and two viral oncoproteins in these immortalized HFKs. We also observed their robust responsiveness to various exogenous stimuli, which was evidenced by increased mRNA expression of epithelial differentiation markers and pro-inflammatory genes in response to three reactive chemicals. In addition, their applicability to cytotoxicity assessment turned out to be comparable to that of HaCaT cells. Finally, we confirmed their differentiation capacity by construction of well-stratified three dimensional skin cultures. These newly established immortalized HFKs will be valuable tools not only for generation of in vitro skin disease models but also for prediction of potential toxicities of various cosmetic chemicals.

ABSTRACT

Human pluripotent stem cells (hPSCs), including embryonic stem cells (ESCs) and induced PSCs (iPSCs), represent potentially unlimited cell sources for clinical applications. Previous studies have suggested that hPSCs may benefit from immune privilege and limited immunogenicity, as reflected by the reduced expression of major histocompatibility complex class-related molecules. Here we investigated the global immune-related gene expression profiles of human ESCs, hiPSCs and somatic cells and identified candidate immune-related genes that may alter their immunogenicity. The expression levels of global immune-related genes were determined by comparing undifferentiated and differentiated stem cells and three types of human somatic cells: dermal papilla cells, ovarian granulosa cells and foreskin fibroblast cells. We identified the differentially expressed genes CD24, GATA3, PROM1, THBS2, LY96, IFIT3, CXCR4, IL1R1, FGFR3, IDO1 and KDR, which overlapped with selected immune-related gene lists. In further analyses, mammalian target of rapamycin complex (mTOR) signaling was investigated in the differentiated stem cells following treatment with rapamycin and lentiviral transduction with specific short-hairpin RNAs. We found that the inhibition of mTOR signal pathways significantly downregulated the immunogenicity of differentiated stem cells. We also tested the immune responses induced in differentiated stem cells by mixed lymphocyte reactions. We found that CD24- and GATA3-deficient differentiated stem cells including neural lineage cells had limited abilities to activate human lymphocytes. By analyzing the transcriptome signature of immune-related genes, we observed a tendency of the hPSCs to differentiate toward an immune cell phenotype. Taken together, these data identify candidate immune-related genes that might constitute valuable targets for clinical applications.

ABSTRACT

Objective@#To investigate the clinical effect of 0.02% clobetasol propionate cream (CPC) on phimosis in prepubertal children.@*METHODS@#We retrospectively analyzed the clinical data about 237 prepubertal children with phimosis present at the Outpatient Department from June 2012 to December 2015. The patients were aged 2-14 (mean 8.6) years, all treated by topical application of 0.02% CPC to the narrowed opening and adhered part of the foreskin twice a day, in the morning and evening respectively. At the time of CPC application, the foreskin was slightly retracted. We evaluated the therapeutic effect every week from the end of the first week of treatment.@*RESULTS@#Totally, 233 of the patients completed the 8-week treatment, of whom 181 (77.68%) showed full retraction of the foreskin, 28 (12.01%) experienced improvement (disappearance of the phimotic ring), and 24 (10.30%) failed to respond, with a total effectiveness rate of 89.70%. No significant local or systemic adverse reactions were observed during the treatment.@*CONCLUSIONS@#Topical application of 0.02% Clobetasol Propionate Cream is a safe, effective, painless, and inexpensive option for the treatment of phimosis in prepubertal chilodren.

ABSTRACT

Objective@#To evaluate the clinical effect of embedding sutures of single inner- and outer-prepuce flap in the treatment of concealed penis.@*METHODS@#This retrospective analysis included 37 cases of concealed penis treated by embedding sutures of single inner- and outer-prepuce flap between July 2011 and May 2015. Catheters were pulled out from the patients within 24 hours and the dressing removed about 1 week after surgery. All the patients were followed up for 12-24 months postoperatively for evaluation of the long-term outcomes of surgery.@*RESULTS@#One-stage wound healing was achieved in all the patients. No foreskin flap necrosis, inflammation, edema, voiding dysfunction, or painful erection was found during the follow-up. The penises were extended by 2-4 cm. No complications were observed axcept 8 cases of mild prepuce edema, which all subsided with 6 months postoperatively.@*CONCLUSIONS@#Embedding sutures of single inner- and outer-prepuce flap, with the advantages of simple operation, rapid recovery and few complications, is a desirable surgical option for the treatment of concealed penis.

ABSTRACT

Objective@#To investigate the risk factors for the complications of urethroplasty in patients with primary hypospadias by postoperative follow-up observation.@*METHODS@#We retrospectively analyzed 110 cases of primary hypospadias repair performed from November 2010 to October 2015, including 70 cases of tubularized incised plate (TIP) urethroplasty and 40 cases of inlay internal preputial graft (IIPG) urethroplasty, all with the urethral plate reserved. We followed up the patients for 15.6-36 months, (27.3 ± 0.52) mo for those with and (26.9 ± 0.22) mo for those without complications. The mean age of the two groups of patients was (7.5 ± 0.2) and (7.0 ± 0.5) yr, respectively.@*RESULTS@#The follow-up data were collected from all the patients, 17 (15.5%) with and 93 (84.5%) without complications. The success rate of surgery was 84.5%. There were no statistically significant differences in the follow-up time and age between the two groups of patients (P >0.05). Single-factor analysis of variance showed significant differences between the complication and non-complication groups in the preoperative urethral opening (P <0.01), ventral penile curvature (P <0.01), and length of urethral defect (P = 0.04), while multiple linear regression analysis exhibited that only ventral curvature was associated with the postoperative complications of the patients (OR = 1.12, 95% CI: 1.06-1.19, P<0.01).@*CONCLUSIONS@#We chose single-stage urethroplasty with the urethral plate reserved for the treatment of primary hypospadias and achieved satisfactory outcomes. Ventral penile curvature is an independent risk factor for the complications of primary hypospadias, and a higher degree of curvature is associated with a higher incidnece of complications.

ABSTRACT

Objective@#To investigate the effect of the frenulum identification positioning method with a disposable suture device in circumcision for the prevention of postoperative penile frenulum malposition.@*METHODS@#Totally 212 patients with phimosis or redundant prepuce underwent circumcision from March 2015 to September 2016, including 109 cases of conventional circumcision (the control group) and 103 cases treated by frenulum identification positioning with a disposable suture device (the observation group). We observed the postoperative position of the penile frenulum and median raphe and compared the deviation angles of the frenulum between the two groups of patients.@*RESULTS@#The median of penile frenulum deviation angle (interquartile range) was 0 (3.56) in the observation group, significantly smaller than 12.41 (19.59) in the control (P <0.001, P = 0.000). And the rate of frenulum deviation was remarkably lower in the former (8.74% [9/103]) than in the latter group (66.06% [72/109]) (P <0.01).@*CONCLUSIONS@#Circumcision using the frenulum identification positioning method with a disposable suture device can effectively avoid postoperative penile frenulum malposition. With the advantages of safety and easy operation, it deserves clinical application and popularization.

ABSTRACT

Objective@#To assess the effect of traversing the vertical pedicle flap (TVPF) for the treatment of severely buried penis in children.@*METHODS@#Totally 43 children with severely buried penis underwentTVPF (n = 21)or modifiedShiraki surgery (control, n = 22) in our hospitalfrom February to December 2014. Wecompared the operation time, intra-operation blood loss, foreskin swelling time, and parents' satisfaction with penile appearance between the two groups.@*RESULTS@#No statistically significant differences were observed between the TVPFand control groups in the operation time ([45.0 ±6.8] vs [42.0 ±5.3] min, P>0.05) or intra-operation blood loss([5.0 ±1.2] vs [6.0 ±0.8] ml, P>0.05). The average foreskin swelling time was markedly shorter in the TVPFgroup than in the control ([9.0 ±2.3] vs [15.0 ±4.8] d, P<0.05)and the parents' satisfaction with penile appearancewas higher in the former than in the latter (95.23vs31.81 %, P<0.05). The elastic bandages were removedfor all the patientsat 3 days postoperatively, and 3 to 6-month follow-up revealed no penile retraction or relapse.@*CONCLUSIONS@#The method of traversing the vertical pedicle flap is a feasible surgical option for the treatment of severely buried penis in children, which can make a rational use of the foreskin,remove the tight ring, and achieve a satisfactory appearance of the penis.

ABSTRACT

O objetivo deste relato de caso é descrever a ocorrência de plasmocitoma em bulbo peniano de um cão, classificado como uma doença extramedular não cutânea de localização rara e casuística inédita. Um cão, sem raça definida, com sete anos de idade e pesando 15kg, não castrado, apresentou histórico clínico de anorexia, vômitos, anúria e constipação. Ao exame específico da genitália externa, foi encontrada uma massa em bulbo peniano durante a inspeção do prepúcio, aderida à pele e encapsulada, extremamente firme e arredondada, medindo cerca de 6cm de diâmetro. Por meio da ultrassonografia dessa estrutura, foi observado aumento do volume regional com ecotextura heterogênea e ecogenicidade mista, além de neovascularização tecidual ao Doppler colorido. Foi realizada biópsia da massa, sendo verificada a presença de neoplasia de células redondas. A caracterização do tumor foi realizada pela imuno-histoquímica, e as células neoplásicas foram imunoexpressas para CD79a e MUM1, indicando o diagnóstico de plasmocitoma extramedular. Embora os tumores penianos em cães sejam os predominantemente venéreos transmissíveis (TVT), e os plasmocitomas sejam neoplasias raras nessa localização, este relato de caso fornece com ineditismo a ocorrência de plasmocitoma extramedular em bulbo peniano de cão, condição ainda não descrita em veterinária.


Non-cutaneous extramedullary plasmacytomas are relatively rare in dogs, affecting mainly the oral cavity and bowel loops. The involvement of the penile bulb has not been described, a fact of great importance for obstetric and veterinary oncology. The aim of this case report is to describe the occurrence of plasmacytoma in a dog's penile bulb, classified as a non-cutaneous extramedullary disease of rare location and unpublished casuistry. A non castrated dog of undefined breed, with seven years of age and weighing 15kg, presented clinical history of anorexia, vomiting, anuria and constipation. By specific examination of the external genitalia, a penile bulb mass was found in the preputial inspection, which was adhered to the encapsulated skin, extremely firm and rounded, measuring approximately 6 cm in diameter. By ultrasound evaluation of the structure in the penile bulb an increase of regional volume with heterogeneous echotexture and mixed echogenicity and tissue neovascularization upon color Doppler was observed. Incisional biopsy of the mass was performed and showed the presence of neoplasia of round cells. The characterization of the tumor was performed by immunohistochemistry and the neoplastic immuno cells were expressed CD79a and MUM1, indicating the diagnosis of extramedullary plasmacytoma. Although the penile tumors in dogs are predominantly transmissible venereal tumors (TVT) and plasmocytomas are rare neoplasms in this location, this case report provides a novel occurrence of extramedullary plasmacytoma in the penile bulb of a dog, a condition not yet described in veterinary.

ABSTRACT

OBJECTIVE: This study sought to determine the serum aminotransferase levels of patients with predialysis chronic kidney disease and establish their relationships with serum creatinine levels and glomerular filtration rate. METHODS: Patients with chronic kidney disease were evaluated between September 2011 and May 2012. Aminotransferase and creatinine serum levels were measured using an automated kinetic method, and glomerular filtration rates were estimated using the Cockroft-Gault and Modification of Diet in Renal Disease formulas to classify patients into chronic kidney disease stages. RESULTS: Exactly 142 patients were evaluated (mean age: 64±16 years). The mean creatinine serum level and glomerular filtration rate were 3.3±1.2 mg/dL and 29.1±13 mL/min/1.73 m2, respectively. Patients were distributed according to their chronic kidney disease stages as follows: 3 (2.1%) patients were Stage 2; 54 (38%) were Stage 3; 70 (49.3%) were Stage 4; and 15 (10.5%) were Stage 5. The mean aspartate aminotransferase and alanine aminotransferase serum levels showed a reduction in proportion to the increase in creatinine levels (p=0.001 and p=0.05, respectively) and the decrease in glomerular filtration rate (p=0.007 and p=0.028, respectively). Alanine aminotransferase and aspartate aminotransferase serum levels tended to be higher among patients classified as stage 2 or 3 compared with those classified as stage 4 or 5 (p=0.08 and p=0.06, respectively). CONCLUSIONS: The aspartate aminotransferase and alanine aminotransferase serum levels of patients with predialysis chronic kidney disease decreased in proportion to the progression of the disease; they were negatively correlated with creatinine levels and directly correlated with glomerular filtration rate. .

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the effect of penile frenulum lengthening in the treatment of premature ejaculation (PE).</p><p><b>METHODS</b>Thirty-four males with PE were enrolled in this study, of whom 8 had received circumcision six months before and 4 had redundant prepuce, all with short frenulum. Those with a history of circumcision underwent reconstruction and lengthening of the frenulum, and those without received frenulum lengthening only.</p><p><b>RESULTS</b>Compared with the baseline, the intravaginal ejaculation latency time (IELT) was significantly increased at 1 month after operation ([1.35 ± 0.49] vs [5.71 ± 2.69] min, t = -9.42, P <0.01), (1.42 ± 0.5) vs (5.31 ± 2.74) min in the patients without circumcision (t = -7.41, P <0.01), (1.12 ± 0.35) vs (7.00 ± 2.20) min in those with circumcision (t = -7.24, P <0.01), and (1.50 ± 0.58) vs (4.75 ± 1.71) min in those with redundant prepuce (t = -3.81, P <0.05). Totally, 94% of the patients were satisfied with their sexual intercourse postoperatively.</p><p><b>CONCLUSION</b>Penile frenulum plays an important role in penile erection. Reconstruction and/or lengthening of the frenulum can prolong penile erection and IELT in PE patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To compare the clinical effects of the circumcision stapler, circumcision cerclage, and traditional circumcision in the treatment of phimosis and redundant prepuce.</p><p><b>METHODS</b>Using the circumcision stapler (group A), foreskin cerclage (group B), and traditional circumcision (group C), we treated 276 patients with phimosis or redundant prepuce. We made comparisons among the three groups in the operation time, intraoperative blood loss, intraoperative and 24-hour postoperative pain scores, and incidence of postoperative complications. Results: The operation time, intraoperative blood loss, and intraoperative pain score were (6.52 ± 2.45) min, (1.93 ± 0.82) ml, and 1.37 ± 0.68 in group A and (7.24 ± 1.86) min, (1.51 ± 0.72) ml, and 1.20 ± 0.79 in group B, all significantly lower than (28. 36 ± 4.22) min, (9.52 ± 3.29) ml, and 3.06 ± 0.75 in group C (P <0.05). The 24-hour postoperative pain score was remarkably higher in group B than in A and C (3. 18 ± 0. 82 vs 1. 85 ± 0. 63 and 1. 82 ± 0. 75, P <0. 05). The incidence rate of postoperative complications was markedly lower in group A than in B (5. 43% vs 14. 13%, P < 0.05), but with no significant differences between either A and C or B and C (P >0.05).</p><p><b>CONCLUSION</b>The circumcision stapler, with its advantages of simple operation, minimal invasiveness, fewer complications, and better cosmetic result, deserves a wider clinical application.</p>

ABSTRACT

Traumatic injury to the male external genitalia is frequently encountered, but acute traumatic dislocation of the penile structure is extremely rare, with only a few reports found in the literature. We herein report the case of a 21-year-old man who sustained blunt trauma to the pelvis following a motor vehicle accident, and had features suspicious of penile dislocation. With the use of computed tomography and bedside ultrasonography, a diagnosis of penile dislocation was made, which was subsequently confirmed intraoperatively. Immediate surgical intervention via gentle manipulation of the penile tissue back to its native position was performed in order to restore normal anatomy. The exact mechanism of penile dislocation is not known. However, circumferential laceration around the foreskin causing degloving injury of the penis is suggested in our patient.
