Purpose: To determine epidemiological characteristics of penile cancer in Rio de Janeiro, its associated risk factors and clinical manifestations. Patients and Methods: Between 2002 and 2008 we evaluated 230 patients at three public institutions, considering age, ethnicity, birthplace, marital status, educational level, religion, tobacco smoking, presence of phimosis and practice of circumcision. Results: The ages ranged from 25 to 98 years, with an average of 58.35 years. Of the 230 patients, 167 (72.7%) were from the southeast region of Brazil (which includes Rio de Janeiro) and 45 (19.5%) were from the northeast of the country. Most patients were white (67.3%), married (58.6%), smokers (56.5%) and had not completed primary school (71.3%). The predominant religion was Catholic (74.8%). Of the 46 (20%) circumcised patients, only 1 (2.2%) had undergone neonatal circumcision. Grade I tumors were present in 87 (37.8%) of the patients, grade II in 131 (56.9%) and grade III in 12 (5.3%). Lymphovascular embolization was observed in 63 (27.3%) and koilocytosis in 124 (53.9%) patients. Of the total, 41.3% had corpora cavernosa or corpus spongiosum infiltration, and 40 (17.4%) had urethral invasion. Prophylactic lymphadenectomy was performed on 56 (36.1%), therapeutic lymphadenectomy on 84 (54.2%) and hygienic lymphadenectomy for advanced disease on 15 (9.7%) patients. The median time between the lesion onset and clinical diagnosis was 13.2 months. The mean follow up was 28.8 months. Conclusion: Most of our patients were born in this state and had low socioeconomic status. Most of them were white men, married, smokers, uncircumcised, of the Catholic faith and in their sixties or older. Their disease was in most cases diagnosed only in the advanced stages.
Objective: To assess the affected skin area and the reconstructive techniques used in 80 patients affected by Fournier's gangrene. Materials and Methods: Eighty patients ranging in age from 19 to 85 years (mean = 51) affected by Fournier's gangrene were studied. When admitted to the emergency room the patients were submitted to clinical and laboratory examinations to analyze the gravity of the case. All patients were submitted to an extensive debridement of the lesion, urinary derivation by cystostomy and colostomy whenever necessary. Results: Only 13 patients (16.25%) died. From the 67 remaining patients, in 44 (65.6%) debridement was restricted to the scrotum, in 10 (14.9%) there has been scrotum and penile lesions and in 13 (19.3%) there has been a debridement of the scrotum and the perineal region. In 11 cases (16.4%) there was no need for reconstructive surgery with wound closing by second intention, in 16 cases (23.8%) reconstructive surgery was performed with mobilization of local skin, in 19 (28.3%) we have used skin grafts, 20 patients (29.8%) needed reconstructive surgery with the use of skin flaps and in 1 case (1.4%) there has been the use of skin flaps and grafts simultaneously. Conclusions: Fournier's gangrene is a serious pathology and should be treated aggressively with an extensive debridement of the area with necrosis. The use of precocious reconstructive surgery of the genitals present good results and tends to greatly reduce the length of hospital stay and improve the psychological conditions of these patients.
Objectives. To provide a better understanding of the distribution of inguinal nodes in order to prevent the complications of unnecessary and extended dissections in penile cancer. Methods. The bilateral inguinal regions of 19 male cadavers were dissected. Nodal distribution was noted and quantified based on anatomical location. The superficial nodes were subdivided into quarters as follows: superomedial, superolateral, inferomedial, and inferolateral. Statistical analysis was performed comparing node distribution between quarters using one-way analysis of variance (ANOVA), and the unpaired T-test was used between superficial and deep nodes. Results. Superficial nodes were found in all inguinal regions studied (mean = 13.60), and their distribution was more prominent in the superomedial quarter (mean = 3.94) and less in the inferolateral quarter (mean = 2.73). There was statistical significance between quarters when comparing the upper group with the lower one (P = 0.02). Nodes were widely distributed in the superficial region compared with deep lymph nodes (mean = 13.60 versus 1.71, P < 0.001). Conclusions. A great number of inguinal lymph nodes are distributed near the classical anatomical landmarks for inguinal lymphadenectomy, more prominent in upper quadrants.
Background: Traumatic lesions to the penis may extend into the corpus spongiosum, causing laceration or complete transection of the urethra. Blunt penile trauma is usually related to sexual intercourse or manipulation. The aim of this paper was to report the authors experience with the management of urethral injuries in patients with penile blunt trauma. Methods: The charts from 77 patients with penile blunt trauma were retrospectively reviewed, and the cases associated with urethral injuries associated were selected. Patient age ranged from 18 to 63 years (mean 33 years). Results: From 77 cases assessed, 11 (14.2%) patients had urethral injury, 62 (80.5%) had injury of the corpora cavernosa and four (5.2%) had injury of the dorsal vein. The etiology of urethral injuries was sexual intercourse in 10 patients (91%) and direct trauma to the flaccid penis in one patient (9%). A partial urethral disruption was presented in eight patients (72.8%) and a total disruption in three patients (27.2%). Preoperative urethrogram was performed in seven patients with a suspicion of urethral trauma. When a partial injury was present the urethra was closed over the catheter, and in the presence of a total injury an end-to-end anastomosis was performed. Conclusion: The data support the reported incidence of urethral injury associated with blunt penile trauma. No clinically apparent urethral structures were appreciated with primary urethral repair after a follow up of more than 6 months.
Introduction Anencephaly is the most severe neural tube defect in human fetuses. There is an increasing need for tissue replacement in chronic diseases and reconstructive surgeries. Fetal tissues have been used as a substitute for native organs. Aim The aim of this article was to compare the structure and morphology of the corpora cavernosa (CC) and spongiosum (SP) of penises from anencephalic and normal human fetuses. Main Outcome Measures The main outcome measures of this study were the proposition of a new model for biological studies and tissue transplantation. Methods We studied 11 penises from normal human fetuses, aged 14–23 weeks postconception (WPC), and five penises from anencephalic fetuses, aged 18–22 WPC. The organs were removed and processed by routine histological and immunolabeling techniques. Analysis of connective tissue (Cot), smooth muscle (SMC), and elastic fiber (EF) were performed in sections. Data were expressed as area density (Ad) using digital processing and software. Means were statistically compared using the unpaired t-test and linear regression was performed. Statistical significance was considered if P < 0.05. Results The intracavernosal septum was present in all samples. We did not observe differences in the Ad of Cot and SMC in the penises of anencephalic fetuses when compared with normal ones. The simple linear regression suggested that during human development, there is a gradual increase in Cot (R2 = +0.45) and a decrease of SMC (R2 = −0.62) in the CC in both groups studied. Elastin was observed only in fetuses from 20th WPC. Conclusions There was no difference in the structure of the CC and corpus SP of anencephalic fetuses compared with normal ones. Elastin was documented from 20th WPC, which suggests the maintenance of erectile function. Histochemistry and immunolabeling suggested that penile shaft development is maintained and unaltered in anencephalic fetuses. Further studies should be performed to analyze anencephalic fetuses as a potential tissue-donating group and a model for biological studies.
