What you need to know: updates in penile cancer staging.

PURPOSE: We sought to discuss the updates in the 8th edition (8E) of The American Joint Committee on Cancer (AJCC) staging for penile cancer and to provide relevant evidence associated with the major changes that occurred. METHODS: A comprehensive search of PubMed® and Web of Science® was performed for relevant English language articles from 2004 through 2019. Literature resulting from this search were reviewed and articles pertinent to penile cancer staging changes were included. RESULTS: Modifications were observed in the tumor and nodal staging. In the 8E AJCC, Ta disease indicates noninvasive localized squamous cell carcinoma, which allows for inclusion of other historical variants. T1 is subcategorized into T1a and T1b according to existence of lymphovascular invasion, perineural invasion and high-grade tumor. This subcategorization demonstrates different risks for lymph node (LN) metastases and will affect decision strategy when opting for inguinal lymphadenectomy. Urethral invasion is no longer a differentiator between T2 and T3 disease, as T2 includes invasion of the corpus spongiosum and T3 involves invasion of the corpus cavernosum. For nodal staging, pN1 has been increased from a single LN metastases to two unilateral inguinal LN metastases, while pN2 has been modified to three or more inguinal LN metastases. This change was evidenced by demonstrating no significant difference in disease specific mortality between the previous edition's pN1 and pN2. CONCLUSIONS: The 8E penile cancer staging provides several modifications that have relevant clinical implications in the management of penile cancer. Nevertheless, it requires refinements that allow for better staging of penile tumors.

Organ Sparing Surgery for Penile Cancer: A Systematic Review.

PURPOSE: Although penile cancer represents only 1% of all male cancers, the traditional treatment, total or subtotal penectomy, carries devastating psychological and functional outcomes. Organ sparing surgery is an attractive option if it can provide satisfactory cancer control equivalent to or nearly equivalent to standard techniques. This approach is meeting increasing acceptance. We offer a timely comprehensive review to increase awareness of these procedures and their applicability, to evaluate the techniques objectively and to provide guidance to the practicing urologist. MATERIALS AND METHODS: A PubMed® search was conducted using the key words "organ sparing/conserving" in "penile cancer" alone or in combination with "partial penectomy," "glansectomy," "glans resurfacing," "penile reconstruction," "laser," "Mohs," "outcomes" and "quality of life." RESULTS: Many techniques of organ sparing surgery in patients with penile cancer have been described through the years. To be practical and useful, a requirement of all these procedures is achievement of complete tumor excision confirmed by negative intraoperative frozen section and final pathological margins. Although organ sparing surgery carries a greater risk of local recurrence than penile amputation, overall patient survival is generally unaffected. Following strict indications and appropriate patient selection cancer specific survival after organ sparing surgery is equivalent to that of established techniques with the added benefits of improved quality of life and more acceptable morbidity. CONCLUSIONS: In properly selected patients with penile cancer organ sparing surgery provides comparable oncologic outcomes to conventional techniques, including total and subtotal amputations. Many patients are able to urinate while standing and a significant number are able to have intercourse.

Partial Nephrectomy in the Overweight Patient: an Overview.

The diagnosis and treatment of kidney cancer continues to evolve with advances in imaging and surgical approaches. The use of nephron sparing surgery (NSS) has become the operation of choice for treating small renal masses. Yet, technical difficulty and a variety of approaches have left debate for best method in the overweight population. This review summarizes the current knowledge in the open, laparoscopic, and robotic approaches to identify key risk factors, general assessments, complication rates, and the influence of body habitus for each approach.

Incidence and predictors of understaging in patients with clinical T1 urothelial carcinoma undergoing radical cystectomy.

OBJECTIVE: To evaluate predictors of understaging in patients with presumed non-muscle-invasive bladder cancer (NMIBC) identified on transurethral resection of bladder tumour (TURBT) who underwent radical cystectomy (RC) with attention to the role of a restaging TURBT. PATIENTS AND METHODS: We retrospectively evaluated 279 consecutive patients with clinically staged T1 (cT1) disease after TURBT who underwent RC at our institution from April 2000 to July 2011. In all, 60 of these cT1 patients had undergone a restaging TURBT before RC. The primary outcome measure was pathological staging of ≥T2 disease at the time of RC. RESULTS: In all, 134 (48.0%) patients were understaged. Of the 60 patients who remained cT1 after a restaging TURBT, 28 (46.7%) were understaged. Solitary tumour (odds ratio [OR] 0.43, 95% confidence interval [CI] 0.25-0.76, P = 0.004) and fewer prior TURBTs (OR 0.84, 95% CI 0.71-1.00, P = 0.05) were independent risk factors for understaging. CONCLUSIONS: Despite the overall improvement in staging accuracy linked to restaging TURBTs, the risk of clinical understaging remains high in restaged patients found to have persistent T1 urothelial carcinoma who undergo RC. Solitary tumour and fewer prior TURBTs are independent risk factors for being understaged. Incorporating these predictors into preoperative risk stratification may allow for augmented identification of those patients with clinical NMIBC who stand to benefit most from RC.

Salvage robotic assisted laparoscopic radical prostatectomy: a single institution, 5-year experience.

PURPOSE: Salvage robotic assisted laparoscopic prostatectomy is a treatment option for certain patients with recurrent prostate cancer after primary therapy. Data regarding patient selection, complication rates and cancer outcomes are scarce. We report the largest, single institution series to date, to our knowledge, of salvage robotic assisted laparoscopic prostatectomy. MATERIALS AND METHODS: We reviewed our database of 4,234 patients treated with robotic assisted laparoscopic prostatectomy at Vanderbilt University and identified 34 men who had surgery after the failure of prior definitive ablative therapy. Each patient had biopsy proven recurrent prostate cancer and no evidence of metastases. The primary outcome measure was biochemical failure. RESULTS: Median time from primary therapy to salvage robotic assisted laparoscopic prostatectomy was 48.5 months with a median preoperative prostate specific antigen of 3.86 ng/ml. Most patients had Gleason scores of 7 or greater on preoperative biopsy, although 12 (35%) had Gleason 8 or greater disease. After a median followup of 16 months 18% of patients had biochemical failure. The positive margin rate was 26%, of which 33% had biochemical failure after surgery. On univariable analysis there was a significant association between prostate specific antigen doubling time and biochemical failure (HR 0.77, 95% CI 0.60-0.99, p = 0.049) as well as between Gleason score at original diagnosis and biochemical failure (HR 3.49, 95% CI 1.18-10.3, p = 0.023). There were 2 Clavien II-III complications, namely a pulmonary embolism and a rectal laceration. Postoperatively 39% of patients had excellent continence. CONCLUSIONS: Salvage robotic assisted laparoscopic prostatectomy is safe, with many favorable outcomes compared to open salvage radical prostatectomy series. Advantages include superior visualization of the posterior prostatic plane, modest blood loss, low complication rates and short length of stay.

Ureteroenteric anastomotic strictures after radical cystectomy-does operative approach matter?

PURPOSE: Robot-assisted laparoscopic radical cystectomy has been increasingly used to decrease the morbidity of radical cystectomy. However, whether it truly lowers the complication rate compared to open radical cystectomy is not well established. We examined the benign ureteroenteric anastomotic stricture rates of open and robot-assisted laparoscopic radical cystectomy. MATERIALS AND METHODS: In the 478 consecutive patients who underwent radical cystectomy at our institution from December 2007 to December 2011 we examined the proportion diagnosed with benign ureteroenteric anastomotic stricture. Clinicopathological variables were compared by treatment group. Cox multivariable analysis was performed to determine which patient or disease specific factors were independently associated with stricture diagnosis. RESULTS: A total of 375 patients (78.5%) underwent open radical cystectomy and 103 (21.5%) underwent robot-assisted laparoscopic radical cystectomy. Of the patients 45 (9.4%) were diagnosed with ureteroenteric anastomotic stricture a median of 5.3 months postoperatively. There was no difference in the stricture rate between the open and robot-assisted groups (8.5% vs 12.6%, p = 0.21). On adjusted Cox proportional hazards analysis no patient variable was independently associated with stricture diagnosis, including operative approach. CONCLUSIONS: Of the patients 9.4% were diagnosed with benign ureteroenteric anastomotic stricture after radical cystectomy with no significant difference in the risk of diagnosis by surgical approach. No patient or disease specific factor was independently associated with an increased risk of stricture diagnosis. Ureteroenteric anastomotic stricture is likely related to surgical technique. Continued efforts are needed to refine the technique of open and robot-assisted laparoscopic radical cystectomy to minimize the occurrence of this critical complication.

Translational Research for Identifying Potential Early-stage Prostate Cancer Biomarkers.

BACKGROUND/AIM: Prostate cancer (PCa) is one of the most common types of cancer in men. Prostate-specific antigen (PSA) is currently the only biomarker used to screen for the risk of developing PCa. Because PSA tests may show false positives, identifying novel PCa-specific biomarkers would improve prediction and diagnosis at an early stage. Previously, we identified a number of genes/microRNAs (miRNAs) in prostate tissue as potential biomarkers of chronic prostatitis in a rat model of chemical-induced prostatitis. The current study aimed to evaluate their potential for use as translational, diagnostic markers in humans. MATERIALS AND METHODS: We performed quantitative polymerase chain reaction analysis using pathologically clear (normal) or confirmed PCa tissue samples from the same patients (N=18 per group). RESULTS: Levels (relative fold changes) of bone morphogenetic protein 7 (BMP7) transcripts were significantly lower in PCa tissues, compared with clear tissues, in a paired t-test (p=0.0075). Although neural cell adhesion molecule 1 (NCAM1) transcripts tended to be altered in PCa tissues, statistically insignificant differences were observed (p=0.0521). No statistically significant differences were observed for the other genes/miRNAs analyzed in PCa tissues due to a high degree of individual variance in expression. CONCLUSION: Similar to the results previously observed in rats, changes in the levels of BMP7 and NCAM1 transcripts were evident in human PCa tissues, suggesting that these genes may serve as potential diagnostic biomarkers during the early stages of PCa. Further studies are needed to determine the potential use of these molecules as biomarkers.

Characterization of virulent West Nile virus Kunjin strain, Australia, 2011.

To determine the cause of an unprecedented outbreak of encephalitis among horses in New South Wales, Australia, in 2011, we performed genomic sequencing of viruses isolated from affected horses and mosquitoes. Results showed that most of the cases were caused by a variant West Nile virus (WNV) strain, WNV(NSW2011), that is most closely related to WNV Kunjin (WNV(KUN)), the indigenous WNV strain in Australia. Studies in mouse models for WNV pathogenesis showed that WNV(NSW2011) is substantially more neuroinvasive than the prototype WNV(KUN) strain. In WNV(NSW2011), this apparent increase in virulence over that of the prototype strain correlated with at least 2 known markers of WNV virulence that are not found in WNV(KUN). Additional studies are needed to determine the relationship of the WNV(NSW2011) strain to currently and previously circulating WNV(KUN) strains and to confirm the cause of the increased virulence of this emerging WNV strain.

Diagnosis, evaluation and follow-up of asymptomatic microhematuria (AMH) in adults: AUA guideline.

PURPOSE: The purpose of this guideline is to provide a clinical framework for the diagnosis, evaluation and follow-up of asymptomatic microhematuria. MATERIALS AND METHODS: A systematic literature review using the MEDLINE® database was conducted to identify peer reviewed publications relevant to the definition, diagnosis, evaluation and follow-up for AMH. The review yielded 191 evidence-based articles, and these publications were used to create the majority of the guideline statements. There was insufficient evidence-based data for certain concepts; therefore, clinical principles and consensus expert opinions were used for portions of the guideline statements. RESULTS: Guideline statements are provided for diagnosis, evaluation and follow-up. The panel identified multiphasic computed tomography as the preferred imaging technique and developed guideline statements for persistent or recurrent AMH as well as follow-up. CONCLUSIONS: AMH is only diagnosed by microscopy; a dipstick reading suggestive of hematuria should not lead to imaging or further investigation without confirmation of three or greater red blood cells per high power field. The evaluation and follow-up algorithm and guidelines provide a systematic approach to the patient with AMH. All patients 35 years or older should undergo cystoscopy, and upper urinary tract imaging is indicated in all adults with AMH in the absence of known benign causation. The imaging modalities and physical evaluation techniques are evolving, and these guidelines will need to be updated as the effectiveness of these become available. Please visit the AUA website at http://www.auanet.org/content/media/asymptomatic_microhematuria_guideline.pdf to view this guideline in its entirety.

Evaluating health-related quality of life as a prognostic tool for overall survival in routine cancer care for older patients with bladder cancer: A US based study.

PURPOSE: Health-related quality of life (HRQoL) outcomes, in addition to being useful for monitoring a person's health and well-being, may also predict overall survival (OS) in cancer patients. This study's objective was to examine the association of longitudinally assessed HRQoL and OS in patients with a history of bladder cancer (BC). MATERIALS AND METHODS: This longitudinal retrospective cohort study used the 1998 to 2013 Surveillance, Epidemiology and End Results database linked with Medicare Health Outcomes Survey. Study cohort included patients having HRQoL assessments both pre- and post-BC diagnosis using Short Form-36/Veterans Rand-12. Using Cox Proportional Hazards adjusted for demographics, tumor characteristics, and surgery type, we studied the associations of 3-point difference in HRQoL assessed pre- and post-BC diagnosis and change from pre-to-post diagnosis with overall survival. RESULTS: The study cohort included 438 BC patients with deceased patients (n = 222; 50.7%) being significantly older than those alive (77.2 vs. 75.4 years; P = 0.004). Adjusting for covariates, a 3-point difference in physical HRQoL (physical component summary [PCS]) pre-, post-, and pre-to-post BC diagnosis was associated with respectively 6.1%, 8.7%, and 7.3% (P < 0.01 for all) decreased risk of death for higher PCS. Similarly, a 3-point difference in mental HRQoL (mental component summary [MCS]) post-BC diagnosis was associated with 4.5% (P < 0.05) decreased risk of death for higher MCS. CONCLUSIONS: Associations between PCS/MCS and OS imply that elderly BC patients with better physical/mental health are more likely to survive longer. Monitoring HRQoL in routine cancer care would facilitate early detection of HRQoL decline and enable timely intervention by clinicians to improve OS.

Short-Term and Long-Term Renal Outcomes in Patients With Obesity After Minimally Invasive Versus Open Partial Nephrectomy for the Treatment of Renal Cancer: Retrospective Study.

BACKGROUND: Obesity is significantly associated with renal cell carcinoma. Surgery is the preferred treatment for demarcated lesions of renal cell carcinoma; however, obesity increases the complexity of surgical outcomes. Minimally invasive surgical techniques are preferred over open partial nephrectomy (OPN), but controversy remains regarding the most efficacious technique in patients with obesity. OBJECTIVE: This study aims to determine whether minimally invasive partial nephrectomy (MIPN) or OPN better preserves renal function and investigate short- and long-term renal outcomes in patients with obesity undergoing a partial nephrectomy. METHODS: We conducted a retrospective chart review of 242 adult patients aged ≥18 years who underwent MIPN or OPN between January 1, 2005, and December 31, 2016, at the University of Arkansas for Medical Sciences. Using creatinine as a measure of kidney function, patients' preoperative levels were compared with their postoperative levels in 2-time frames: short (3-6 months postsurgery) or long (>6 months). The primary outcome was the change in creatinine values from preoperative to >6 months postoperatively in patients with obesity. Secondary outcomes included the change in creatinine values from preoperative to 3 to 6 months postoperatively in patients with obesity who underwent MIPN versus OPN. We also analyzed the creatinine values of nonobese patients (BMI <30) who underwent partial nephrectomy using the same time frames. Unconditional logistic regression was used to estimate crude and multivariable-adjusted odds ratios (ORs) and 95% CI to observe associations between surgery type and changes in creatinine values from while stratifying for obesity. RESULTS: A total of 140 patients were included in the study, of whom 75 were obese and 65 were nonobese. At >6 months after MIPN (n=20), the odds of patients with obesity having a decrease or no change in creatinine values was 1.24 times higher than those who had OPN (n=13; OR 1.24, 95% CI 0.299-6.729; P=.80). At 3 to 6 months after MIPN (n=27), the odds were 0.62 times lower than those after OPN (n=17; OR 0.62, 95% CI 0.140-2.753; P=.56). In the nonobese group, at 3 to 6 months after undergoing minimally invasive surgery (n=18), the odds of having a decrease or no change in creatinine values was 4.86 times higher than those who had open surgery (n=21; OR 4.86, 95% CI 1.085-21.809; P=.04). At more than 6 months after MIPN (n=14), the odds were 4.13 times higher than those after OPN (n=11; OR 4.13, 95% CI 0.579-29.485; P=.16). CONCLUSIONS: We observed a nonstatistically significant preservation of renal function in patients with obesity who underwent OPN at 3 to 6 months postoperatively. Conversely, after 6 months, the same was true for MIPN, indicating the long-term benefit of MIPN. In the nonobese group, MIPN was favored over OPN.

Prostate size as a predictor of Gleason score upgrading in patients with low risk prostate cancer.

PURPOSE: Gleason score upgrading between biopsy and surgical pathological specimens occurs in 30% to 50% of cases. Predicting upgrading in men with low risk prostate cancer may be particularly important since high grade disease influences management decisions and impacts prognosis. We determined whether prostate size predicts Gleason score upgrading in patients with low risk prostate cancer. MATERIALS AND METHODS: A total of 1,251 consecutive patients with D'Amico low risk disease and complete data available underwent radical prostatectomy at our institution between January 2000 and June 2008. Patients were divided into 3 groups by pathological Gleason score, including no, minor (3 + 4 = 7) and major (4 + 3 = 7 or greater) Gleason score upgrading. We developed bivariate and multivariate models to determine whether prostate size was an important predictor of upgrading while controlling for clinical and biopsy characteristics. RESULTS: Of 1,251 cases 387 (31.0%) were upgraded, including 324 (26%) and 63 (5%) with minor and major upgrading, respectively. As expected, Gleason score upgrading was associated with worse pathological and cancer control outcomes. On multivariate analysis smaller prostate size was an independent predictor of any and major upgrading (OR 0.58, 95% CI 0.48-0.69, p <0.01 and OR 0.67, 95% CI 0.49-0.96, p = 0.03, respectively). Men with prostate volume at the 25th percentile (36 cm(3)) were 50% more likely to experience upgrading than men with prostate volume at the 75th percentile (58 cm(3)). CONCLUSIONS: Of low risk cases 31% were upgraded at final pathology. Smaller prostate size predicts Gleason score upgrading in men with clinically low risk prostate cancer. This is important information when counseling patients on management and prognosis.

Determining factors for hospital discharge status after radical cystectomy in a large contemporary cohort.

PURPOSE: We describe hospital discharge status in patients after radical cystectomy for bladder cancer. We determined factors affecting discharge status. MATERIALS AND METHODS: The 445 patients underwent radical cystectomy for urothelial carcinoma from January 2004 to December 2007. Patients were grouped by hospital discharge status into 1 of 4 groups, including home under self-care without services, home with home health services, subacute, rehabilitation or skilled nursing facility, or hospice/in-hospital mortality. We compared clinical, perioperative and pathological variables in these groups. We also examined the association of discharge status with the hospital readmission rate and 90-day mortality. RESULTS: Of the 440 patients 250 (56.8%), 145 (32.9%), 39 (8.9%) and 6 (1.4%) were in the home without services, home with services, facility and mortality groups, respectively. On multivariate analysis older age, lower preoperative albumin, unmarried status and higher Charlson comorbidity index were predictors of discharge home with services while older age, poor preoperative exercise tolerance and longer hospital stay predicted discharge to a facility. Patients in the facility group were more likely to die within 90 days of surgery than those who returned home independently or with services. There was no difference in the likelihood of rehospitalization. CONCLUSIONS: Sociodemographic factors, preoperative performance status, and comorbidities and perioperative factors contribute to the discharge decision after radical cystectomy. Some subgroups can be predicted to have increased postoperative care needs and may be appropriate targets for disposition planning preoperatively.

Effect of preoperative nutritional deficiency on mortality after radical cystectomy for bladder cancer.

PURPOSE: Poor preoperative nutritional status is a risk factor for adverse outcomes after major surgery. We evaluated the effect of preoperative nutritional deficiency on perioperative mortality and overall survival in patients undergoing radical cystectomy for bladder cancer. MATERIALS AND METHODS: A total of 538 patients underwent radical cystectomy for urothelial carcinoma between January 2000 and June 2008, and had nutritional parameters documented. Patients with preoperative albumin less than 3.5 gm/dl, body mass index less than 18.5 kg/m(2) or preoperative weight loss greater than 5% of body weight were considered to have nutritional deficiency. Primary outcomes were 90-day mortality and overall survival. Survival was estimated using Kaplan-Meier analysis and compared using the log rank test. Cox proportional hazards models were used for multivariate survival analysis. RESULTS: Of 538 patients 103 (19%) met the criteria for nutritional deficiency. The 90-day mortality rate was 7.3% overall (39 deaths), with 16.5% in patients with nutritional deficiency and 5.1% in the others (p < 0.01). Nutritional deficiency was a strong predictor of death within 90 days on multivariate analysis (HR 2.91; 95% CI 1.36, 6.23; p < 0.01). Overall survival at 3 years was 44.5% (33.5, 54.9) for nutritionally deficient patients and 67.6% (62.4, 72.2) for those who were nutritionally normal (p < 0.01). On multivariate analysis nutritional deficiency cases had a significantly higher risk of all cause mortality (HR 1.82; 95% CI 1.25, 2.65; p < 0.01). CONCLUSIONS: Nutritional deficiency, as measured by preoperative weight loss, body mass index and serum albumin, is a strong predictor of 90-day mortality and poor overall survival. Prospective studies are needed to demonstrate the best indices of preoperative nutritional status and whether nutritional intervention can alter the poor prognosis for patients treated with radical cystectomy who have nutritional deficiencies.

Tumor volume as a predictor of adverse pathologic features and biochemical recurrence (BCR) in radical prostatectomy specimens: a tale of two methods.

PURPOSE: The prognostic value of tumor volume in predicting biochemical recurrence after prostatectomy has been debated. Our aim in this study was to (a) evaluate tumor volume as an independent predictor of adverse pathologic outcomes and BCR and (b) determine the effect of two different methods of tumor volume estimation. METHODS: We reviewed the charts of 3,087 patients who underwent radical prostatectomy at Vanderbilt University Medical Center between 2000 and 2008; of which 1,747 patients had data sufficient for analysis. Prostate specimens were processed as whole mount between 2000 and 2003 and then via systematic sampling from 2003 to 2008, with tumor volume measured by planimetry in the whole-mount group and tumor volume estimated by percent tumor involvement in the systematic sampling group. RESULTS: Tumor volume estimates were higher with SS than with WM. There were significant associations between larger tumor volume and adverse pathological outcomes, regardless of pathologic method (all with P<0.001). Controlling for other pathologic parameters, tumor volume was an independent predictor of PGS, EPE, and SM in logistic regression models (P<0.001 for TV in all models). Tumor volume was demonstrated to be an independent predictor of BCR in the WM group (1.06, 95% CI 1.01-1.11, P=0.013), though tumor volume was not a significant predictor of BCR in the SS group. CONCLUSIONS: Though the prognostic value of tumor volume is debated, our data demonstrate that tumor volume, when calculated via planimetry on whole-mount pathologic sectioning, is a significant predictor of biochemical recurrence after prostatectomy.

Presence of SARS-CoV-2 RNA in Semen-Cohort Study in the United States COVID-19 Positive Patients.

On 31 December 2019, China informed the World Health Organization they were facing a viral pneumonia epidemic of a new type of Coronavirus. Currently, 10 months later, more than 43,000,000 people have been infected, and about 1,150,000 deceased worldwide from the disease. Knowledge about the virus is updated daily, and its RNA was isolated from several human secretions, e.g., throat, saliva, pulmonary alveolar washing, and feces. So far, only one publication found the presence of SARS-CoV-2 in semen. In this 5-month cross-sectional study, we recruited 15 patients diagnosed with a positive nasal swab for SARS-CoV-2 with no or mild symptoms in our institution. A semen sample after a shower was retrieved and tested for viral RNA in the semen. The samples were tested for the viral RNA with RT-PCR with two different genetic probes. The samples were re-tested 24 h after the first test to confirm the results. The SARS-Cov-2 viral RNA was present in 1/15 patients [6.66%] in our sample. Even in a small sample, the RNA from SARS-CoV-2 can be isolated from human semen. This information should alert the scientific community and public health officials about a possible new form of transmission of the disease and long-term clinical effects on the population.

Early Postoperative Complications and Factors Associated with Early vs Late Discharge of Patients Undergoing Colporrhaphy for Pelvic Organ Prolapse: A National Report.

INTRODUCTION: Pelvic organ prolapse is a highly prevalent condition that is commonly managed with surgical intervention. Our purpose was to determine associated factors and postoperative morbidity rates of early (≤1 day) vs late (>1 day) hospital discharge after outpatient colporrhaphy. METHODS: From the National Surgical Quality Improvement Program® database, 11,652 female patients who received colporrhaphy between 2005 and 2016 were identified; 3,728 were stratified into the early discharge group and 7,924 into the late discharge group. Patient characteristics, surgical data and 30-day postoperative complications were recorded, and variables were compared between groups. RESULTS: In comparison to the late discharge group, the early discharge group had a shorter mean operating time (p <0.001) and overall was less likely to suffer from 30-day morbidity (OR 0.67 [95% CI 0.55-0.82]), reoperation (OR 0.59 [95% CI 0.39-0.90]) or readmission (OR 0.40 [95% CI 0.26-0.90]). Factors independently associated with a lower likelihood of early discharge included age ≥55 years, higher body mass index, White race, current smoker, American Society of Anesthesiologists® classification IV/V and longer operating time. Increased likelihood of early discharge was associated with receiving colporrhaphy after 2012 and posterior colporrhaphy. CONCLUSIONS: Patients discharged from the hospital early had lower rates of postoperative morbidity than those discharged later. Early discharge was associated with procedures performed after 2012 and with isolated posterior colporrhaphy. Longer hospital stays were associated with longer operating times and older age, White race, obesity, comorbidities and history of smoking.

Changing Trends in Management Following Artificial Urinary Sphincter Surgery for Male Stress Urinary Incontinence: An Analysis of the National Surgical Quality Improvement Program Database.

OBJECTIVE: To characterize the safety and practice patterns of artificial urinary sphincter (AUS) placement on a population level. Increasingly AUS implantation has shifted to be an outpatient surgery; however, there is a lack of large-scale research evaluating factors associated with early (≤ 24 hours) versus late (>24 hours) discharges and complications in men following AUS placement. We utilized the National Surgical Quality Improvement Program (NSQIP) database to identify and compare factors and outcomes associated with each approach. METHODS: NSQIP database was queried for men undergoing AUS placement between 2007 and 2016. Patients were classified as either early discharge (ED ≤ 24 hours) and late discharge (LD > 24 hours). Baseline demographics, operating time, and complications were compared between the 2 groups. Multivariate logistic regression evaluated factors associated with discharge timing and 30-day complications. RESULTS: A total of 1176 patients were identified and were classified as ED in 232 and LD in 944 patients. Operative time was shorter in ED (83 minutes) compared to LD (95 minutes, P < .001). Hypertension was more prevalent among LD patients (60.3% vs 69.1% for ED and LD respectively, P < .001). The 30-day complication rate was similar in both groups (ED: 4.3% vs LD: 3.4%, P = .498). Multivariable analysis revealed that surgery after 2012 was associated with ED (OR = 3.66, P < .001). CONCLUSION: At the national level, there are no differences in postoperative morbidity between early and late discharges. There is a trend toward more ED, specifically after 2012. A prospective study on the feasibility and safety of outpatient AUS is needed.

Concurrent Penile Prosthesis and Artificial Urinary Sphincter versus Penile Prosthesis and Male Sling: A National Multi-Institutional Analysis of National Surgical Quality Improvement Program Database Comparing Postoperative Morbidity.

PURPOSE: We aimed to assess the 30-day morbidity in patients undergoing combined insertion of penile prosthesis (PP) and artificial urinary sphincter (AUS) vs. PP and male sling (MS). MATERIALS AND METHODS: The National Surgical Quality Improvement Program database was queried to identify patients who underwent placement of AUS or MS combined with PP. Patient demographics, postoperative morbidity including complications, readmission and reoperation rates were recorded. Student t-test and chi-square or Fischer's exact test were used as appropriate. RESULTS: Forty-one patients met selection criteria between 2010 and 2016. Overall, 26 patients received PP and AUS vs. 15 that received PP and MS. Average age was similar in both groups (64.8±6.6 years vs. 62.3±6.3 years, p=0.254). Diabetes mellitus was more prevalent in PP+MS group compared to AUS+PP group (46.7% vs. 11.5%, p=0.022). Average length of stay was higher in PP+AUS group compared to PP+MS group (2.2±0.6 days vs. 1.8±0.4 days, p=0.017). Postoperative morbidity was reported in four patients in PP+AUS group. No reported complications in PP+MS group. In PP+AUS group, complications included one patient who developed urinary tract infection, one developed surgical site infection, readmission in two for postoperative infection, and one return to the operating room. No reported prosthesis explantation or revision in either groups. CONCLUSIONS: Our results showed that 30-day morbidity was recorded in the PP+AUS group and none in the PP+MS group. The complication and readmission rates remain comparable to the previous reports in both groups.

Robotic assisted laparoscopic prostatectomy versus radical retropubic prostatectomy for clinically localized prostate cancer: comparison of short-term biochemical recurrence-free survival.

PURPOSE: We compared biochemical recurrence-free survival of patients who underwent radical retropubic prostatectomy vs robot assisted laparoscopic prostatectomy in concurrent series at a single institution. MATERIALS AND METHODS: A total of 2,132 patients were treated between June 2003 and January 2008. We excluded from study patients with prior treatment (115), missing data (83) and lymph node involvement (30). The remaining cohort (1,904) was compared based on clinical, surgical and pathological factors. Kaplan-Meier analysis was performed comparing biochemical recurrence after robot assisted laparoscopic prostatectomy and radical retropubic prostatectomy. A Cox proportional hazards model was generated to determine whether surgical approach is an independent predictor of biochemical recurrence. RESULTS: There were 491 radical retropubic prostatectomies (25.9%) and 1,413 robot assisted laparoscopic prostatectomies (74.1%) performed, and median followup was 10 months (IQR 2 to 23). On univariate analysis the robot assisted laparoscopic prostatectomy group was slightly lower risk with lower median prostate specific antigen (5.4 vs 5.8, p <0.01), a lower proportion of pathological grade 7-10 (48.5% vs 54.7%, p <0.01) and lower pathological stage (80.5% pT2 vs 69.6% pT2, p <0.01). The 3-year biochemical recurrence-free survival rate was similar between the robot assisted laparoscopic prostatectomy and radical retropubic prostatectomy groups on the whole as well as when stratified by pathological stage, grade and margin status. On multivariate analysis extracapsular extension (p <0.01), pathological grade 7 or greater (p <0.01) and positive surgical margin (p <0.01) were independent predictors of biochemical recurrence while surgical approach was not. CONCLUSIONS: The likelihood of biochemical recurrence was similar between groups when stratified by known risk factors of recurrence. Surgical approach was not a significant predictor of biochemical recurrence in the multivariate model. Our analysis is suggestive of comparable effectiveness for robot assisted laparoscopic prostatectomy, although longer term studies are needed.
