Retzius-sparing robot-assisted radical prostatectomy (RS-RARP) has been shown to improve continence. However, questions remain regarding feasibility and generalizability of technique and outcomes.To compare the outcomes of 140 consecutive standard robot-assisted radical prostatectomy (S-RARP) versus RS-RARP.A total of 70 S-RARPs were performed followed by 70 RS-RARPs. Demographic, pathologic, and functional outcomes were compared preoperatively and through 12 mo. Expanded Prostate Cancer Index Composite for Clinical Practice (EPIC-CP) was used to compare functional outcomes. Logistic and linear regression analyses were utilized to analyze variables associated with EPIC-CP urinary incontinence and overall quality of life (QOL) scores, and oncologic outcomes. Cox regression analysis was used to analyze incontinence at 12 mo.RS-RARP versus S-RARP.Patient and tumor characteristics (age, body mass index, prostate-specific antigen, Charlson Comorbidity Index, Gleason group, clinical stage, and Prostate Imaging Reporting and Data System score), perioperative outcomes (console time, estimated blood loss, postoperative complications, and length of stay), oncologic outcomes (positive surgical margin [PSM], and biochemical recurrence), overall and 12-mo continence rates (zero pads and zero to one safety pad), time to continence, potency (erection sufficient for sexual activity), EPIC-CP urinary incontinence, sexual function, and overall QOL scores.Median follow-up for S-RARP versus RS-RARP was 46.3 versus 12.3 mo. RS-RARP versus S-RARP had improved overall continence rates at total follow-up (95.7% vs 85.7%, p = 0.042) and 12-mo follow-up (97.6% vs 81.4%, p = 0.002), and faster return to continence (zero to one safety pad, 44 vs 131 d, p 0.001). RS-RARP EPIC-CP urinary incontinence and overall QOL scores remained significantly better at 12 mo. There were no differences in overall PSM rates, although RS-RARP had lower rates of nonfocal PSMs. There were no differences in sexual function. In multivariate analysis, RS-RARP was significantly associated with improved 12-mo EPIC-CP urinary incontinence and improved QOL scores, but was not associated with PSM or biochemical recurrence. Limitations include retrospective study design and unequal follow-up; however, significantly better RS-RARP continence at 12 mo is striking despite fewer patients attaining 12-mo follow-up.RS-RARP significantly improves early and long-term continence without compromising oncologic outcomes and leads to overall improved QOL.Retzius-sparing robot-assisted radical prostatectomy is an emerging technique for robotic radical prostatectomy that improves urinary function and quality of life without compromising cancer control.

Radical prostatectomy has undergone many adaptations since its inception, including the Retzius-sparing robotic-assisted radical prostatectomy approach. In this article, we review the origins of radical prostatectomy, the theoretic basis for Retzius-sparing robotic-assisted radical prostatectomy, and outline the key steps of the procedure. To date, there have been 9 studies comparing the outcomes of Retzius-sparing robotic-assisted radical prostatectomy with standard robotic-assisted radical prostatectomy, which have demonstrated improved continence outcomes for Retzius sparing robotic assisted radical prostatectomy within the first year and equivalent oncologic efficacy out to 18 months. Further research is needed to evaluate sexual function outcomes as well as long-term oncologic outcomes.

Background Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) has improved urinary function compared with standard robotic-assisted radical prostatectomy (S-RARP). As RS-RARP spares the dorsal vascular complex, pelvic fascia, and anterior abdominal fascia, it may also lower the incidence of “neglected” postprostatectomy sequelae such as penile shortening, Peyronie’s disease, and inguinal hernias. Objective To determine whether there are patient-perceived differences in penile shortening, Peyronie’s disease, and inguinal hernia rates among men undergoing RS-RARP versus S-RARP. Design, setting, and participants Researchers uninvolved in clinical care and blinded to surgical approach surveyed 60 RS-RARP versus 57 S-RARP men with validated patient-reported items to assess penile shortening, Peyronie’s disease, and inguinal hernia sequelae following surgery. Intervention RS-RARP versus S-RARP. Outcome measurements and statistical analysis Univariate differences between the two cohorts were analyzed using Student t test. Logistic regression was used to analyze variables associated with postoperative penile shortening. Cox proportional hazards models were used to assess the risk of developing Peyronie’s disease and inguinal hernia postoperatively. Results and limitations RS-RARP was associated with less patient-reported penile shortening (41.7% vs 64.9%, p = 0.012), Peyronie’s disease (0% vs 8.7%, p = 0.020), and inguinal hernia (0.0% vs 13.0%, p = 0.004). In adjusted analyses, RS-RARP (odds ratio [OR] 0.24, 95% confidence interval [CI] 0.09–0.63, p = 0.004) was associated with lower odds of penile shortening, while a higher body mass index was associated with increased odds of penile shortening (OR 1.13, 95% CI 1.01–1.26, p = 0.037). RS-RARP was not associated with a decreased risk of Peyronie’s disease on Cox proportion hazard model; however, these models are limited due to a limited number of events in our cohort. Limitations include retrospective design, patient-reported outcomes, and small cohorts. Conclusions RS-RARP is associated with less patient-reported penile shortening and may decrease the risk of Peyronie’s disease and postoperative inguinal hernia development. These new findings add to research, showing improved urinary continence and quality of life following RS-RARP; however, a prospective study is needed to validate these findings. Patient summary Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is an evolving surgical technique for prostate cancer treatment, which has shown improved postoperative urinary control compared with the standard technique, likely due to preservation of natural pelvic anatomy. Our findings suggest that the preservation of normal pelvic anatomy during RS-RARP may also reduce the risk of postprostatectomy penile shortening, Peyronie’s disease, and inguinal hernia., Take Home Message Retzius-sparing robotic-assisted radical prostatectomy (RS-RARP) is an evolving surgical technique for prostate cancer treatment that has shown improved postoperative urinary control compared with the standard technique, likely due to the preservation of natural pelvic anatomy.

Objective To evaluate the outcomes of men diagnosed with prostate cancer (CaP) following implanted treatments for advanced heart failure. Given the increasingly favorable 10-year life expectancy, MedStar Washington Hospital Center screens heart transplant (HT) candidates for CaP and other malignancies prior to intervention. Methods Men aged 18-90 with available pretransplant Prostate Specific Antigen (PSA) who underwent left ventricular assist device (LVAD) and/or HT at MedStar Washington Hospital Center from 2007 to 2018 were identified. Serum PSA, CaP diagnosis, and treatment were captured and analyzed. Survival was analyzed using Kaplan-Meier curves. Results Data were available for 34 patients. Median age was 53 [IQR = 51-58]. Median follow-up was 77 months (95% CI = 40-87 months). Six men had postimplant elevated PSA (5.3; SD = 8.5) and 4 were diagnosed with CaP. Median age of CaP diagnosis was 59 [IQR = 58.5-62). As of 2018, 31 of the 34 patients were living, and none died from CaP. Five-year survival was 96% in those without CaP and 100% in those with CaP (Figure 2). Conclusion Our cohort represents the largest known cohort with heart failure treated by LVAD and/or HT and CaP. Our median age of 59 at CaP diagnosis is considerably younger than the national median of 66. 1 Of the 4 individuals diagnosed with CaP, 3 had high-grade disease. Given the favorable long-term survival of these patients post-LVAD and/or HT, age-appropriate treatment for CaP should be continued postimplantation.

Primary adenomas are common in the gastrointestinal tract but exceedingly rare on the periurethral surface and vagina. The pathogenesis remains unknown but vaginal adenomas are hypothesized to arise from vaginal adenosis or embryonic cloacal remnants and possess malignant potential. We present a case of a large primary vaginal tubulovillous adenoma in an eighty-one-year-old, likely diethylstilbestrol naïve patient. To the best of our knowledge the patient's 7.4 x 4.5 × 1.4 cm primary vaginal tubulovillous adenoma is the largest ever reported in literature., Highlights - Primary vaginal adenomas in diethylstilbestrol naïve patients are exceedingly rare - Vaginal adenomas have malignant potential and must be fully resected - There is no consensus on management of primary vaginal adenomas

Background The incidence of infected urolithiasis is unknown, and evidence describing the optimal management strategy for obstruction is equivocal. Objective To examine the trends of infected urolithiasis in the United States, the practice patterns of competing treatment modalities, and to compare adverse outcomes. Design, setting, and participants A weighted estimate of 396385 adult patients hospitalized with infected urolithiasis was extracted from the Nationwide Inpatient Sample, 1999–2009. Outcome measurements and statistical analysis Time trend analysis examined the incidence of infected urolithiasis and associated sepsis, as well as rates of retrograde ureteral catheterization and percutaneous nephrostomy (PCN) for urgent/emergent decompression. Propensity-score matching compared the rates of adverse outcomes between approaches. Results and limitations Between 1999 and 2009, the incidence of infected urolithiasis in women increased from 15.5 (95% confidence interval [CI], 15.3–15.6) to 27.6 (27.4–27.8)/100 000); men increased from 7.8 (7.7–7.9) to 12.1 (12.0–12.3)/100000. Rates of associated sepsis increased from 6.9% to 8.5% ( p =0.013), and severe sepsis increased from 1.7% to 3.2% ( p p =0.150). Among those undergoing immediate decompression, 113 459 (28.6%), PCN utilization decreased from 16.1% to 11.2% ( p =0.001), with significant regional variability. In matched analysis, PCN showed higher rates of sepsis (odds ratio [OR]: 1.63; 95% CI, 1.52–1.74), severe sepsis (OR: 2.28; 95% CI, 2.06–2.52), prolonged length of stay (OR: 3.18; 95% CI, 3.01–3.34), elevated hospital charges (OR: 2.71; 95%CI, 2.57–2.85), and mortality (OR: 3.14; 95%CI, 13–4.63). However, observational data preclude the assessment of timing between outcome and intervention, and disease severity. Conclusions Between 1999 and 2009, women were twice as likely to have infected urolithiasis. Rates of associated sepsis and severe sepsis increased, but mortality rates remained stable. Analysis of competing treatment strategies for immediate decompression demonstrates decreasing utilization of PCN, which showed higher rates of adverse outcomes. These findings should be viewed as preliminary and hypothesis generating, demonstrating the pressing need for further study.

Purpose Robotic-assisted laparoscopic prostatectomy (RALP) offers reportedly comparable oncologic outcomes for localized disease compared with open radical retropubic prostatectomy (ORRP). However, the oncologic efficacy of RALP in locally-advanced prostate cancer (PCa) is less clear. We report and compare our experience with RALP and ORRP in men with locally advanced PCa. Methods Patients with locally advanced PCa (stage T3 or greater) were identified in both robotic and open cohorts. Clinicopathologic features including age, clinical stage, prostate-specific antigen, surgical margins, and Gleason score were reviewed. We further examined the incidence of positive surgical margins, the effect of the surgical learning curve on margins, and the need for adjuvant therapy. Results From 1997 to 2010, 1,011 patients underwent RALP and 415 patients were identified who underwent radical retropubic prostatectomy (RRP) across four institutions. 140 patients in the RALP group and 95 in the RRP group had locally advanced PCa on final pathology. The overall robotic positive margin rate 47.1% compared with 51.4% in the RRP group. A trend towards a lower positive margin rate was seen after 300 cases in the RALP group, with 66.7% positive margin rate in the first 300 cases compared with 41.8% in the latter 700 cases. In addition, a lower incidence of biochemical recurrence was also noted in the latter cases (30.6% vs. 9.5%). Conclusions Up to 2 out of 3 men undergoing RALP for locally-advanced PCa had positive margins during our initial experience. However, with increasing surgeon experience the overall positive margin rate decreased significantly and was comparable to the positive margin rate for patients with locally advanced disease undergoing ORRP over four academic institutions. We also noted a lower incidence of biochemical recurrence with increasing RALP experience, suggesting better oncologic outcomes with higher volume. Given this data, RALP has comparable oncologic outcomes compared to ORRP, especially with higher volume surgeons.

Although the use of minimally invasive radical prostatectomy (MIRP) has increased, there are few comprehensive population-based studies assessing temporal trends and outcomes relative to retropubic radical prostatectomy (RRP).Assess temporal trends in the utilization and outcomes of MIRP and RRP among US Medicare beneficiaries from 2003 to 2007.A population-based retrospective study of 19 594 MIRP and 58 638 RRP procedures was performed from 2003 to 2007 from the 100% Medicare sample, composed of almost all US men ≥ 65 yr of age.MIRP and RRP.We measured 30-d outcomes (cardiac, respiratory, vascular, genitourinary, miscellaneous medical, miscellaneous surgical, wound complications, blood transfusions, and death), cystography utilization within 6 wk of surgery, and late complications (anastomotic stricture, ureteral complications, rectourethral fistulae, lymphocele, and corrective incontinence surgery).From 2003 to 2007, MIRP increased from 4.9% to 44.5% of radical prostatectomies while RRP decreased from 89.4% to 52.9%. MIRP versus RRP subjects were younger (p0.001) and had fewer comorbidities (p0.001). Decreased MIRP genitourinary complications (6.2-4.1%; p = 0.002), miscellaneous surgical complications (4.7-3.7%; p=0.030), transfusions (3.5-2.2%; p=0.005), and postoperative cystography utilization (40.3-34.1%; p0.001) were observed over time. Conversely, overall RRP perioperative complications increased (27.4-32.0%; p0.001), including an increase in perioperative mortality (0.5-0.8%, p=0.009). Late RRP complications increased, with the exception of fewer anastomotic strictures (10.2-8.8%; p=0.002). In adjusted analyses, RRP versus MIRP was associated with increased 30-d mortality (odds ratio [OR]: 2.67; 95% confidence interval [CI], 1.55-4.59; p0.001) and more perioperative (OR: 1.60; 95% CI, 1.45-1.76; p0.001) and late complications (OR: 2.52; 95% CI, 2.20-2.89; p0.001). Limitations include the inability to distinguish MIRP with versus without robotic assistance and also the lack of pathologic information.From 2003 to 2007, there were fewer MIRP transfusions, genitourinary complications, and miscellaneous surgical complications, whereas most RRP perioperative and late complications increased. RRP versus MIRP was associated with more postoperative mortality and complications.

Although subtle technical variation affects potency preservation during robot-assisted laparoscopic radical prostatectomy (RARP), most prostatectomy studies focus on achieving the optimal anatomic nerve-sparing dissection plane. However, the impact of active assistant/surgeon neurovascular bundle (NVB) countertraction on sexual function outcomes has not been studied or quantified.To illustrate technique and compare sexual function outcomes for nerve sparing without (NS-0C) versus with (NS-C) assistant and/or surgeon NVB countertraction.This is a retrospective study of 342 NS-0C versus 268 NS-C RARP procedures performed between August 2008 and February 2011.RARP.We used the Expanded Prostate Cancer Index Composite (EPIC) sexual function and potency scores, estimated blood loss (EBL), operative time, and positive surgical margin (PSM).In unadjusted analysis, men undergoing NS-0C versus NS-C were older, had worse baseline sexual function, higher biopsy and pathologic Gleason grade, and higher preoperative prostate-specific antigen (PSA) levels (all p ≤ 0.023). However, NS-0C versus NS-C was associated with higher 5-mo sexual function scores (20 vs 10; p0.001), and this difference was accentuated for bilateral intrafascial nerve sparing in preoperatively potent men (35.8 vs 16.6; p0.001). Similarly, 5-mo potency for preoperatively potent men was better with bilateral intrafascial NS-0C versus NS-C (45.0% vs 28.4%; p = 0.039). However, no difference in sexual function or potency was observed at 12 mo. In adjusted analyses, NS-0C versus NS-C was associated with improved 5-mo sexual function (parameter estimate: 10.90; standard error: 2.16; p0.001) and potency (odds ratio: 1.69; 95% confidence interval, 1.01-2.83; p = 0.046). NS-0C versus NS-WC was associated with shorter operative times (p = 0.001) and higher EBL (p = 0.001); however, there were no significant differences in PSM. Limitations include the retrospective, single-surgeon study design and smaller numbers for 12-mo comparison.Reliance on countertraction to facilitate dissecting NVB away from the prostate leads to neuropraxia and delayed recovery of sexual function and potency. Subtle technical modification to dissect the prostate away from the NVB without countertraction enables earlier return of sexual function and potency.

Background Large prostate size, median lobes, and prior benign prostatic hyperplasia (BPH) surgery may pose technical challenges during robot-assisted laparoscopic prostatectomy (RALP). Objective To describe technical modifications to overcome BPH sequelae and associated outcomes. Design, settings, and participants A retrospective study of prospective data on 951 RALP procedures performed from September 2005 to November 2010 was conducted. Outcomes were analyzed by prostate weight, prior BPH surgical intervention ( n =59), and median lobes >1cm ( n =42). Surgical procedure RALP. Measurements Estimated blood loss (EBL), blood transfusions, operative time, positive surgical margin (PSM), and urinary and sexual function were measured. Results and limitations In unadjusted analysis, men with larger prostates and median lobes experienced higher EBL (213.5 vs 176.5ml; p p =0.002), and larger prostates were associated with more transfusions (4 vs 1; p =0.037). Operative times were longer for men with larger prostates (164.2 vs 149.1min; p =0.002), median lobes (185.8 vs 155.0min; p =0.004), and prior BPH surgical interventions (170.2 vs 155.4min; p =0.004). Men with prior BPH interventions experienced more prostate base PSM (5.1% vs 1.2%; p =0.018) but similar overall PSM. In adjusted analyses, the presence of median lobes increased both EBL ( p =0.006) and operative times ( p p =0.014). However, prostate size did not affect EBL, PSM, or recovery of urinary or sexual function. Conclusions Although BPH characteristics prolonged RALP procedure times and increased EBL, prostate size did not affect PSM or urinary and sexual function.

To assess contemporary characteristics, hospital admissions, charges, and mortality in patients with prostate cancer (CaP) who have bone metastases and skeletal-related events in an observational study.Relying on the Nationwide Inpatient Sample (NIS), patients with CaP with bone metastases between 1998 and 2010 were abstracted. Patients who experienced skeletal-related events were identified, and hospital charges were calculated. Generalized linear regression analyses focused on in-hospital mortality.Between 1998 and 2010, a weighted estimate of 443,929 CaP visits with bone metastases was recorded. Of these, 15.9% experienced at least 1 SRE. The rate of SRE decreased from 18% to 15.4% (1998-2010, estimated annual percent change [EAPC] =-1.44%, P = 0.005) and the SRE-associated mortality decreased from 8.5% to 4.7% (1998-2010, EAPC =-3.68%, P = 0.004). Nevertheless, the inflation-adjusted charges associated with hospital visits of patients with CaP with bone metastases rose by 92% to $1,512,449,106 (EAPC = +8.82%, P0.001), and SRE charges rose by 94% to $369,256,799 (EAPC =+7.62%, P0.001). Predictors of in-hospital mortality in patients with SRE included age (odds ratio [OR] = 1.02), comorbidities (≥3 vs. 0-1, OR = 1.72), SRE of the upper limb (OR = 1.75), SRE of the lower limb (OR = 1.35), spinal cord compression (OR = 1.48), radiation (OR = 0.68), surgery (OR = 0.32), and year of hospitalization (2010 vs. 1998, OR = 0.54; all P0.03).From 1998 to 2010, the incidence of SRE and SRE-associated mortality in patients with CaP and bone metastases decreased. However, charges for SRE-associated hospitalizations have increased alarmingly. Future health care policies should strive to provide cost-effective prevention and management of SREs in this population.

Objectives Although high-volume hospitals have been associated with improved outcomes for radical prostatectomy (RP), the association of residency or fellowship teaching institutions or both and this volume-outcome relationship remains poorly described. We examine the effect of teaching status and hospital volume on perioperative RP outcomes. Methods and materials Within the Nationwide Inpatient Sample, we focused on RPs performed between 2003 and 2007. We tested the rates of prolonged length of stay beyond the median of 3 days, in-hospital mortality, and intraoperative and postoperative complications, stratified according to teaching status. Multivariable logistic regression analyses further adjusted for confounding factors. Results Overall, 47,100 eligible RPs were identified. Of these, 19,193 cases were performed at non-teaching institutions, 24,006 at residency teaching institutions, and 3,901 at fellowship teaching institutions. Relative to patients treated at non-teaching institutions, patients treated at fellowship teaching institutions were healthier and more likely to hold private insurance. In multivariable analyses, patients treated at residency (OR = 0.92, P = 0.015) and fellowship (OR = 0.82, P = 0.011) teaching institutions were less likely to experience a postoperative complication than patients treated at non-teaching institutions. Patients treated at residency (OR = 0.73, P P = 0.045) teaching institutions were less likely to experience a prolonged length of stay. Conclusions More favorable postoperative complication profile and shorter length of stay should be expected at residency and fellowship teaching institutions following RP. Moreover, postoperative complication rates were lower at fellowship teaching than at residency teaching institutions, despite adjustment for potential confounders.
