Novel Scrotal Reconstruction after Fournier's Gangrene Using the Integra™ Dermal Regeneration Template.

We report a novel use of the Integra™ dermal regeneration template to facilitate a functional recovery in a young male with Fournier's gangrene. After multiple debridements he had a large soft tissue defect and local flaps were not possible for reconstruction. Integra™ facilitated reconstruction of a neo-scrotum to allow a good cosmetic outcome.

Penile Squamous Cell Carcinoma After a Childhood Hypospadias Repair With Bladder Mucosa Graft.

Bladder mucosa grafts were historically used for hypospadias surgical repairs, when preputial or penile skin was unavailable and in cases of prior failed hypospadias repairs. We present a case of advanced penile squamous cell carcinoma diagnosed 22 years after a childhood hypospadias repair with a free bladder mucosa graft.

Impact of the 2012 American Urological Association vasectomy guidelines on postvasectomy outcomes in a military population.

OBJECTIVE: To evaluate the impact of the 2012 American Urological Association vasectomy guidelines on postvasectomy clinical outcomes in a highly mobile military cohort and compare these outcomes with those of civilian counterparts. METHODS: The records of service members who underwent vasectomy between January 2008 and December 2013 and provided at least 1 postvasectomy semen analysis (PVSA) were analyzed in the context of the 2012 guidelines. Time to occlusive success, repeat PVSAs and vasectomies, and health care cost savings were compared between our prior definition of vasectomy success, which required azoospermia, and the 2012 criteria, which included rare nonmotile sperm. RESULTS: Of the 1623 men who underwent vasectomy, 738 men (45%) failed to submit a PVSA, leaving 895 men (55%) who provided at least 1 PVSA. A total of 1084 PVSAs were obtained in these men, who had a mean age of 37 ± 6 years. Defining success as azoospermia on first PVSA resulted in a sterility rate of 69%. After application of the 2012 guidelines, 845 patients (94%) achieved sterility by the first PVSA and more patients achieved sterility 60 days from vasectomy (96% vs 72%; P <.001). Inclusion of rare nonmotile sperm in our definition of success would have allowed 228 men to forego a second PVSA and prevented 2 (0.002%) unnecessary vasectomies, a savings of $6297. CONCLUSION: PVSA compliance in our military cohort was similar to that of civilian counterparts. The American Urological Association vasectomy guidelines have the potential to decrease the number of repeat vasectomies and laboratory tests, improve the documented success rate, and increase follow-up compliance when applied to a military population.

Tumor percent involvement predicts prostate specific antigen recurrence after radical prostatectomy only in men with smaller prostate.

PURPOSE: We determined the predictive power of tumor percent involvement on prostate specific antigen recurrence in patients when stratified by prostate weight. MATERIALS AND METHODS: Data on 3,057 patients who underwent radical prostatectomy between 1988 and 2008 was retrieved from our institutional prostate cancer database. Patients with data on tumor percent involvement, prostate volume and prostate specific antigen recurrence were included in analysis. Patients were divided into 3 groups based on prostate volume less than 35, 35 to 45 and greater than 45 cc. The variables tumor percent involvement, age at surgery, race, prostate specific antigen, pathological Gleason score, positive surgical margins, extraprostatic extension, seminal vesicle invasion and surgery year were analyzed using the chi-square and Mann-Whitney tests to determine individual effects on prostate specific antigen recurrence. Tumor percent involvement and prostate specific antigen were evaluated as continuous variables. Significant variables on univariate analysis were included in multivariate Cox regression analysis to compare their effects on prostate specific antigen recurrence. RESULTS: Tumor percent involvement significantly predicted prostate specific antigen recurrence in men with a small prostate (p = 0.006) but not in those with a prostate of greater than 35 cc. Black race was a marginally significant predictor of prostate specific antigen recurrence in men with a medium prostate (p = 0.055). Age at surgery was a predictor of prostate specific antigen recurrence in men with a larger prostate (p = 0.003). Prostate specific antigen, positive surgical margins, seminal vesicle invasion and pathological Gleason score 7 or greater predicted prostate specific antigen recurrence in men with all prostate sizes. CONCLUSIONS: In men with a prostate of less than 35 cc tumor percent involvement is an important variable when assessing the risk of prostate specific antigen recurrence. Tumor percent involvement and prostate volume should be considered when counseling patients and determining who may benefit from heightened surveillance after radical prostatectomy.

Tumor volume, tumor percentage involvement, or prostate volume: which is predictive of prostate-specific antigen recurrence?

OBJECTIVES: To compare the effects of tumor volume (TV), tumor percentage involvement (TPI), and prostate volume (PV) on prostate-specific antigen (PSA) recurrence (PSAR) after radical prostatectomy (RP). METHODS: A cohort of 3528 patients receiving RP between 1988 and 2008 was retrieved from the Duke Prostate Center. Patients were stratified by TV (< 3, 3-6, > 6 cm(3)), TPI (< 10%, 10%-20%, > 20%), and PV (< 35, 35-45, > 45 cm(3)) and their effects on PSAR evaluated using Kaplan-Meier analysis. Clinicopathologic variables included in univariate analysis were age at surgery, race, year of surgery, PSA, pathologic Gleason score, pathologic tumor stage, margin status, extracapsular extension, and seminal vesicle invasion. The effects of TV, TPI, and PV (as continuous and categorical variables) on PSAR were compared using Cox analysis. RESULTS: TPI, TV, and PV were predictive of PSAR (P <.05) in Kaplan-Meier analysis. In multivariate analysis as continuous variables, TPI and PV were predictive of PSAR (hazard ratio [HR] = 1.16 and HR = 0.65, P <.05). As categorical variables, TPI > 20% and PV 10-35 cm(3) were predictive of PSAR (HR = 1.45 and OR = 1.25, P <.05). TV was not predictive of PSAR in either analysis. Pathologic Gleason score > or = 7, PSA, positive margins, seminal vesicle invasion, and tumor stage T3/T4 were found to be predictors of PSAR (P <.05). CONCLUSIONS: TV, TPI, and PV were predictive of PSAR in univariate analysis, but in multivariate analysis, only TPI and PV were predictive of PSAR. TPI and PV should be considered when evaluating, assessing, and counseling patients regarding PSAR risk.

Public survey and survival data do not support recommendations to discontinue prostate-specific antigen screening in men at age 75.

OBJECTIVES: To evaluate the US Preventative Services Task Force (USPSTF) recommendation to discontinue prostate-specific antigen (PSA) screening at age 75. METHODS: Public survey: A cohort of 340 patients was surveyed at our PSA screening clinic and stratified by awareness of the recommendation and education level. Age (< 75, >or= 75), race, health insurance status, knowledge of prostate cancer, and opinion on screening discontinuation at age 75 was evaluated between groups. Disease risk and survival analysis: A cohort of 4196 men who underwent radical prostatectomy between 1988 and 2008 was stratified into age groups: < 65, 65-74, and >or= 75. Associations between clinicopathologic variables, disease risk, and survival were compared between age groups using univariate and multivariate analysis. RESULTS: Approximately 78% of men surveyed disagreed with the USPSTF recommendation. The number of men who disagreed was not significantly different between awareness groups (P = .962). Awareness of new screening guidelines showed a significant difference (P = .006) between education groups. Age >or= 75 years was predictive of high-risk disease based on D'Amico's criteria (odds ratio = 2.72, P = .003). Kaplan-Meier and Cox regression analyses showed an association of men aged >or= 75 years with higher rate of PSA recurrence, distant metastasis, and disease specific death compared with the age groups of < 65 and 65-74 (P <.05). CONCLUSIONS: Men presenting to our PSA screening clinic disagreed with discontinuation of screening at age 75. Men aged >or= 75 years had higher risk disease and poorer survival. The USPSTF recommendation was supported neither by public opinion nor disease risk and survival results.

Men older than 70 years have higher risk prostate cancer and poorer survival in the early and late prostate specific antigen eras.

PURPOSE: We clarified whether men older than 70 years have a higher risk of prostate cancer and poorer survival in the early and late prostate specific antigen eras. MATERIALS AND METHODS: A cohort of 4,561 men who underwent radical prostatectomy were stratified into 3 age groups (younger than 60, 60 to 70 and older than 70 years), and early and late prostate specific antigen eras based on the year of surgery (before 2000 and 2000 or later). Race, body mass index, prostate specific antigen, prostate weight, tumor volume, pathological Gleason sum, pathological tumor stage, extracapsular extension, seminal vesicle invasion and surgical margin status were submitted for univariate and multivariable analyses against the previously mentioned groups. Survivals (prostate specific antigen recurrence, distant metastasis and disease specific death) were compared among the 3 age groups using univariate and multivariable methods. RESULTS: Compared with younger age groups (younger than 60, 60 to 70 years) men older than 70 years had a higher proportion of pathological tumor stage 3/4 (33.0 vs 44.3 vs 52.1%, p <0.001), pathological Gleason sum greater than 7 (9.5% vs 13.4% vs 17.2%, p <0.001) and larger tumor volume (3.7 vs 4.7 vs 5.2 cc, p <0.001). Pathological Gleason sum in men older than 70 years did not differ between the early and late prostate specific antigen eras (p = 0.071). Men older than 70 years had a higher risk of prostate specific antigen recurrence, distant metastasis and disease specific death on univariate (p <0.05) but not multivariable analysis. CONCLUSIONS: Men older than 70 years had higher risk disease and poorer survival in the early and late prostate specific antigen eras. Pathological Gleason sums did not change between the 2 eras. Patient age was an important variable in prostate specific antigen screening, biopsy, treatment and prognosis.

Delayed prostate-specific antigen recurrence after radical prostatectomy: how to identify and what are their clinical outcomes?

OBJECTIVES: To identify factors that predict delayed (> 5 years) prostate-specific antigen recurrence (PSAR) after radical prostatectomy (RP) and to analyze the associated clinical outcomes. METHODS: A cohort of 4561 men who underwent RP between 1988 and 2008 was retrieved from the Duke University Prostate Center database. Among them, 1207 (26.5%) had PSAR and were included in this study. The cohort was then divided into 2 groups; PSAR before 5 years (early PSAR) and PSAR after 5 years (delayed PSAR), and Kaplan Meier analysis was performed. Univariate and logistic regression analysis was carried out to determine significant predictors of delayed PSAR, using factors such as race, age, body mass index, PSA, surgical margin status, pathologic Gleason sum, pathologic tumor stage, and prostate weight. RESULTS: There was a marginal difference between the early and delayed PSAR groups with regard to metastasis-free survival (P = .062). A significant difference in disease-specific survival was found between the 2 groups (P = .025). Patients with pathologic Gleason sums < 7 were more likely to have delayed PSAR as compared to those with pathologic Gleason sums > 7 (OR = 2.38). Patients with a PSA < 10 ng/mL were more likely to have delayed PSAR in comparison to those with PSA > 20 ng/mL (OR = 2.38). CONCLUSIONS: Approximately 90% of PSAR occurred within 5 years after RP. Lower pathologic Gleason sums and lower PSA at diagnosis were associated with delayed PSAR. Patients with delayed PSAR have a disease-specific survival advantage as compared to men with early PSAR.

Factors predicting prostatic biopsy Gleason sum under grading.

PURPOSE: We determined clinical factors affecting the under grading of biopsy Gleason sum compared with prostatectomy pathology and developed a model predicting the probability of under grading. MATERIALS AND METHODS: We analyzed a cohort of 1,701 patients treated for prostate cancer at our institution between 1988 and 2007 with complete biopsy and pathological data available. Patients with a biopsy Gleason sum of 7 or less were included in our analysis. Cases were categorized as under graded or not under graded by comparing biopsy and radical prostatectomy Gleason sums. Logistic regression was used to determine the predictors of under grading based on clinical variables (race, age at diagnosis, body mass index, prostate weight, diagnostic prostate specific antigen, biopsy positive-to-total core ratio, maximal cancer percent in positive cores and time from diagnosis to surgery). A nomogram was developed to calculate the probability of under grading. Results were validated using bootstrapping. RESULTS: Under grading occurred in 46.6% of our cohort. Significant variables predicting under grading were age at diagnosis, biopsy Gleason sum, diagnostic prostate specific antigen, prostate weight, biopsy positive-to-total core ratio and maximal percent of cancer in cores (p <0.05). Nomogram predictive accuracy was 72.4%. CONCLUSIONS: The risk of Gleason sum under grading can be predicted to a satisfactory level using our nomogram. Predicting under grading would improve patient consulting and identify those who should consider repeat biopsy, ultimately enhancing the accuracy of prostate cancer diagnosis.

Risk stratification in the hormonal treatment of patients with prostate cancer.

Prostate cancer (PCa) is the most common type of cancer found in American men, other than skin cancer. The American Cancer Society estimates that there will be 186,320 new cases of prostate cancer in the United States in 2008. About 28,660 men will die of this disease this year and PCa remains the second-leading cause of cancer death in men. One in six men will get PCa during his lifetime and one in 35 will die of the disease. Today, more than 2 million men in the United States who have had PCa are still alive. The death rate for PCa continues to decline, chiefly due to early detection and treatment, and improved salvage therapy such as hormone therapy (HT). HT continues to be a mainstay for primary-recurrent PCa and locally-advanced PCa. However, HT is associated with many undesirable side effects including sexual dysfunction, osteoporosis and hot flashes, all of which can lead to decreased quality of life (QOL). These risks are seen in both long- and short-term HT regimens. Additionally, research in recent years has revealed trends related to clinico pathological variables and their predictive ability in HT outcomes. Awareness of the potential adverse effects, the risks associated with HT and the prognostic ability of clinical and pathological variables is important in determining optimal therapy for individual patients. A rigorous evaluation of the current scientific literature associated with HT was conducted with the goal of identifying the most favorable balance of benefits and risks associated with HT.

Fibrin sealant as tissue glue: preliminary experience in complex genital reconstructive surgery.

OBJECTIVES: To report the outcomes of graft take and wound healing in the first reported series in which fibrin sealant was used as a tissue glue in the reconstruction of complex genital skin loss. METHODS: Between July 2001 and July 2005, 18 men requiring complex genital reconstruction underwent repair by two surgeons at our medical centers. Skin graft reconstruction was required in 6 men. Complete scrotal disassembly with extensive scrotal or thigh flaps was required for reconstruction of 12 others. In the skin graft cases, a thin layer of dilute fibrin sealant was sprayed on the recipient site immediately before graft apposition. In flap cases, fibrin sealant was injected beneath the flap to promote tissue adherence and prevent fluid accumulation. All wounds were followed up postoperatively and observed for evidence of graft take, seroma or hematoma formation, drainage, and infection. RESULTS: The 6 skin graft patients required a total of nine split-thickness skin grafts, all of which had 100% take. Of the 12 patients requiring flap reconstruction, 11 had excellent results. One flap case had a partial wound breakdown, but this reconstruction was performed immediately subsequent to a significant debridement and irrigation procedure in the same setting. Overall, 17 (94.4%) of 18 patients had no wound infection, seroma, hematoma, or other complications. CONCLUSIONS: Fibrin sealant performs very well as a tissue glue and appears to be a useful adjunct in cases of complex genital skin loss reconstruction.
