Risk of Postoperative Thromboembolism in Men Undergoing Urological Prosthetic Surgery: An Assessment of 21,413 Men.

PURPOSE: We assessed venous thromboembolism (VTE) and associated risk factors following artificial urinary sphincter (AUS) and inflatable penile prosthesis (IPP) surgery. MATERIALS AND METHODS: Using IBM® MarketScan, a commercial claims database, patients undergoing AUS and IPP surgery were identified using CPT® and ICD (International Classification of Diseases)-10 procedure codes between 2008 and 2017. ICD-9 and -10 codes were used to identify health care visits associated with lower extremity deep vein thrombosis (DVT) and pulmonary embolism (PE) within 90 days of surgery. Covariates were assessed using a multivariable model to determine association with outcome of DVT and/or PE. RESULTS: A total of 21,413 men underwent AUS (4,870) or IPP (16,543) surgery between 2008 and 2017 with a median age of 62 years and 68 years, respectively. DVT and PE events following AUS and IPP surgery occurred in 1.54% and 1.04%, respectively. A history of varicose veins (HR 2.76; 95% CI 1.11-6.79), prior history of DVT (HR 13.65; 95% CI 7.4-25.19), or PE (HR 7.65; 95% CI 4.01-14.6) in those undergoing AUS surgery was highly associated with development of postoperative VTE. Likewise, prior history of DVT (HR 12.6; 95% CI 7.99-19.93) and PE (HR 8.9; 95% CI 5.6-14.13) was strongly associated with a VTE event following IPP surgery. CONCLUSIONS: In a large cohort of men undergoing AUS and IPP surgery, 1.54% and 1.04% of men experienced a VTE event within 90 days of surgery, respectively. Prior history of varicose veins, DVT, and PE was associated with an increased likelihood of developing a postoperative DVT or PE.

Pubectomy and urinary reconstruction provides definitive treatment of urosymphyseal fistula following prostate cancer treatment.

OBJECTIVE: To describe the natural history, reconstructive solutions, and functional outcomes of those men undergoing pubectomy and urinary reconstruction after prostate cancer treatment. PATIENTS AND METHODS: This study retrospectively identified 25 patients with a diagnosis of urosymphyseal fistula (UF) following prostate cancer therapy who were treated with urinary reconstruction with pubectomy. This study describes the natural history, reconstructive solutions, and functional outcomes of this cohort. RESULTS: All 25 patients had a history of pelvic radiotherapy for prostate cancer. The median (interquartile range [IQR]) time from prostate cancer treatment to diagnosis of UF was 11 (6, 16.5) years. The vast majority of men (24/25; 96%) presented with debilitating groin pain during ambulation. Posterior urethral stenosis was common (20/25; 80%), with 60% having repetitive endoscopic treatments. Culture of pubic bone specimens demonstrated active infection in 80%. Discordance between preoperative urine and intraoperative bone cultures was common, 21/22 (95.5%). After surgery, major 90-day complications (Clavien-Dindo Grade III and IV) occurred in eight (32%) patients. Pain was significantly improved, with resolution of pain (24/25; 96%) and restoration of function, the median (IQR) preoperative Eastern Cooperative Oncology Group Performance Status (ECOG PS) was 3 (2, 3) vs median postoperative ECOG PS score of 0 (0, 1). CONCLUSION: Endoscopic urethral manipulation after radiation for prostate cancer is a risk factor for UF. Conservative management will not provide symptom resolution. Fistula decompression, bone resection, and urinary reconstruction effectively treats chronic infection, improves pain and ECOG PS scores.

New perspectives on the surgical treatment of posterior urethral obstruction.

PURPOSE OF REVIEW: Posterior urethral obstruction (PUO) from prostate surgery for benign and malignant conditions poses a significant reconstructive challenge. Endoscopic management demonstrates only modest success and often definitive reconstructive solutions are necessary to limit morbidity and firmly establish posterior urethral continuity. This often demands a combined abdominoperineal approach, pubic bone resection, and even sacrifice of the external urinary sphincter and anterior urethral blood supply. Recently, a robotic-assisted approach has been described. Enhanced instrument dexterity, magnified visualization, and adjunctive measures to assess tissue quality may enable the reconstructive surgeon to engage posterior strictures deep within the confines of the narrow male pelvis and optimize functional outcomes. The purpose of this review is to review the literature regarding endoscopic, open, and robotic management outcomes for the treatment of PUO, and provide an updated treatment algorithm based upon location and complexity of the stricture. RECENT FINDINGS: Contingent upon etiology, small case series suggest that robotic bladder neck reconstruction has durable reconstructive outcomes with acceptable rates of incontinence in carefully selected patients. SUMMARY: Initial reports suggest that robotic bladder neck reconstruction for recalcitrant PUO may offer novel reconstructive solutions and durable function outcomes in select patients.

Multicenter Experience Using Collagen Fleece for Plaque Incision With Grafting to Correct Residual Curvature at the Time of Inflatable Penile Prosthesis Placement in Patients With Peyronie's Disease.

BACKGROUND: Adjuvant maneuvers are often necessary to correct residual curvature during inflatable penile prosthesis (IPP) placement in patients with Peyronie's disease (PD). AIM: We present our multicenter experience using collagen fleece as graft material for plaque incision and grafting (PIG) during IPP placement in patients with moderate to severe PD. METHODS: We retrospectively reviewed 51 patients with IPP from 3 sites who underwent PIG with Tachosil (Baxter, IL) collagen fleece. Coloplast (Minneapolis, MN) IPP devices were used. Factors associated with residual curvature, revision, and patient satisfaction were performed using chi-squared analysis. OUTCOMES: We evaluated postoperative outcomes including factors associated with residual curvature, revision, and patient satisfaction. RESULTS: The mean compound curvature was 69.6°. The mean follow-up was 10.6 (range 1-38) months. All patients reported erections sufficient for penetrative intercourse at the last follow-up. Residual curvature <15° was noted in 6 of 51 (12%) patients. 3 patients required device revision. 2 patients experienced temporary glanular paresthesia, and no patients experienced device infection. CLINICAL IMPLICATIONS: In our multicenter study, patients experienced substantial curve correction with minimal complications, and in the few patients who had persistent mild curvature, severe preoperative curvature (>60°) was found to be the only risk factor. STRENGTHS & LIMITATIONS: Our study represents the largest series of patients coming from multiple centers undergoing surgical correction of PD with IPP and collagen fleece grafting. Limitations of this study include the retrospective study design, lack of a comparison group, and modest follow-up. CONCLUSION: PIG using collagen fleece is a safe and effective means of correcting residual curvature after IPP placement in patients with moderate to severe PD.

High Rates of Discordant Ureteral Perfusion During Open Ureteral Reconstruction With Indocyanine Green: Does Near-Infrared Fluorescence Imaging Change Management or Stricture Outcomes?

OBJECTIVE: To determine the role of near-infrared fluorescence imaging (NIFI) combined with indocyanine green (ICG) to assess ureteral tissue perfusion in a benign genitourinary reconstruction cohort with a high prevalence of prior abdominopelvic radiation and surgery. MATERIALS AND METHODS: A prospective, single-surgeon series, between June 2018 and April 2022, of patients who underwent open genitourinary reconstructive surgeries in which NIFI/ICG was utilized to intraoperatively assess ureteral tissue perfusion prior to ureteral anastomosis. Primary outcome was ureteroanastomotic stricture (UAS). Secondary outcomes included impact of NIFI/ICG on surgical decision-making and ureter resection length. RESULTS: Thirty nine patients, median age 66, underwent 40 multimodality reconstructive surgeries during which NIFI/ICG was utilized in the open setting. Radiation-induced etiology was present in 32 of 40 (80%) patients. UAS occurred in 1 of 57 (1.8%) anastomoses with median follow-up of 23.4 months. Use of NIFI/ICG changed intraoperative decision-making in 63% of cases. Change in intraoperative decision-making was more common in patients with prior abdominopelvic radiation (66%) compared to non-radiated patients (13%), P = .007. Discordance between subjective (white-light) and objective (NIFI/ICG) ureteral perfusion (white-light) occurred in 61% of ureters. Mean length of resected ureter was higher following objective assessment with NIFI/ICG (3.6 cm) versus subjective assessment (white light) conditions (1.8 cm), P = .001. CONCLUSION: Use of NIFI/ICG was associated with low rates of UAS at 2-year follow-up in a cohort with high prevalence of prior radiation. NIFI/ICG was associated with longer lengths of ureter resection and ureteral perfusion assessment discordance compared to subjective surgeon assessment under white-light conditions.

Comparison of Urinary Diversion in Patients With Prostatic Fistula to Those with Localized Radiation Injury After Radiotherapy for the Treatment of Prostate Cancer.

OBJECTIVE: To compare characteristics and outcomes in patients who had radiotherapy (RT) for prostate cancer (PCa) and underwent urinary diversion (UD) due to prostatic fistula (Fistula) vs localized radiation injury (Localized). METHODS: This study was a retrospective single-institution study. Exclusion criteria included follow-up <3 months, large pelvic tumor, and surgery for cancer control. The Fistula group included fistulization outside of the urinary tract (rectal, soft tissue, thigh, pubic symphysis, and extensive necrosis surrounding the prostate). The group Localized had a multitude of problems; however, all were confined to the urinary tract. Patient characteristics, perioperative variables, and outcomes were compared between groups. RESULTS: Sixty-nine patients were included and had UD from 2009-2022. Median age and time from RT to UD were 73 (interquartile range (IQR) 67.9, 78.1) and 7.3 (IQR 3.2, 12.5) years. There were 29 (42%) and 40 (58%) patients in the Fistula and Localized groups. The Fistula group had a higher rate of abdominal/perineal approach (62.1% vs 12.5%, P <.001), a lower rate of right colon pouch (17.2% vs 40%, P = .043), and a longer operative time (515.7 vs 414.2 minutes, P = .017). Clavien-Dindo complications ≥3 were higher in the Fistula group (44.8% vs 20%, P = .027), including a higher rate of re-operation for recurrent pelvic abscess (37.9% vs 5%, P <.001). Survival for the cohort was 85.5% and did not differ between groups. CONCLUSION: Patients with prostate fistula after RT for PCa undergoing UD had longer, more complex operations, and higher rates of complications, notably post-operative pelvic abscesses, compared to men with localized RT injury. Long-term survival was comparable in both groups.

Variation in Provider Practice Patterns and the Perceived Need for a Shared Decision-making Tool for Neurogenic Lower Urinary Tract Dysfunction.

OBJECTIVE: To evaluate neurogenic lower urinary tract dysfunction (NLUTD) care providers' current practice patterns, their perceived need for a shared decision-making tool for NLUTD management. METHODS: We developed an electronic survey to assess multiple factors surrounding NLUTD management including practice patterns, perceived need for a decision aid and willingness to use it. Prior to survey dissemination, a panel of expert NLUTD care providers reviewed and provided a critique of the survey. It was delivered via email to the members of the Genitourinary Reconstructive Surgeons, and the Society of Urodynamics, female pelvic medicine and urogenital reconstruction between March and May 2022. RESULTS: A total of 117 NLUTD care providers from 11 countries participated in this survey. Most participants were urologists (n: 109, 93%) working at academic teaching hospitals (n: 82, 70%). The most common treatments the providers had provided for stress urinary incontinence and detrusor overactivity were sling procedures (n: 76, 65%) and anticholinergics (n: 111, 95%). Participants believed that NLUTD management can be highly patient-specific and extensively vary from one individual to another. Most participants believed that patients performing clean intermittent catheterization have better QoL compared to those utilizing indwelling urinary catheters (n: 81, 69%). Participants believed there is a need for a NLUTD decision aid, and they expressed their willingness to use one if available. CONCLUSION: We found discordances between guideline recommendations, provider practice patterns, and patient-reported outcome measures and essential attributes that indicated the need for a decision aid to improve patient-provider communication and shared decision-making in NLUTD management.

The "Minimal-Touch" Technique for Artificial Urinary Sphincter Placement: Description and Outcomes.

OBJECTIVE: The study aimed to describe "minimal-touch" technique for primary artificial urinary sphincter placement and evaluate early device outcomes by comparing it with a historical cohort. MATERIALS AND METHODS: We identified patients who underwent primary artificial urinary sphincter placement at our institution from 1983 to 2020. Statistical analysis was performed to identify the rate of postoperative device infection in patients who underwent minimal touch versus those who underwent our traditional technique. RESULTS: 526/2601 total procedures (20%) were performed using our "minimal-touch" approach, including 271/1554 patients (17%) who underwent primary artificial urinary sphincter placement over the study period. Around 2.3% of patients experienced device infection after artificial urinary sphincter procedures. In the "minimal-touch" era, 3/526 patients (0.7%) experienced device infection, including 1/271 (0.4%) of those with primary artificial urinary sphincter placement. In comparison, 46/2075 patients (2.7%) experienced device infection using the historical approach, with 29/1283 (2.3%) of primary artificial urinary sphincter placements resulting in removal for infection. Notably, 90% of device infections occurred within the first 6 months after primary placement. The difference in cumulative incidence of device infections at 12 months did not meet our threshold for statistical significance for either the total cohort of all AUS procedures (primary and revision) or the sub-group of only those patients undergoing primary artificial urinary sphincter placement (Gray K-sample test; P=.13 and .21, respectively). CONCLUSION: The "minimal-touch" approach for artificial urinary sphincter placement represents an easy-to-implement modification with potential implications on device outcomes. While early results appear promising, longer-term follow-up with greater statistical power is needed to determine whether this approach will lower the infection risk.

Prior COVID-19 infection associated with increased risk of newly diagnosed erectile dysfunction.

We sought to assess if COVID-19 infection recovery is associated with increased rates of newly diagnosed erectile dysfunction. Using IBM MarketScan, a commercial claims database, men with prior COVID-19 infection were identified using ICD-10 diagnosis codes. Using this cohort along with an age-matched cohort of men without prior COVID-19 infection, we assessed the incidence of newly diagnosed erectile dysfunction. Covariates were assessed using a multivariable model to determine association of prior COVID-19 infection with newly diagnosed erectile dysfunction. 42,406 men experienced a COVID-19 infection between January 2020 and January 2021 of which 601 (1.42%) developed new onset erectile dysfunction within 6.5 months follow up. On multivariable analysis while controlling for diabetes, cardiovascular disease, smoking, obesity, hypogonadism, thromboembolism, and malignancy, prior COVID-19 infection was associated with increased risk of new onset erectile dysfunction (HR 1.27; 95% CI 1.1-1.5; P = 0.002). Prior to the widespread implementation of the COVID-19 vaccine, the incidence of newly diagnosed erectile dysfunction is higher in men with prior COVID-19 infection compared to age-matched controls. Prior COVID-19 infection was associated with a 27% increased likelihood of developing new-onset erectile dysfunction when compared to those without prior infection.

Postoperative Opioid Prescribing Following Outpatient Male Urethral Surgery: Evidence for Change.

INTRODUCTION: Surgeons play a central role in the opioid epidemic. We aim to evaluate the efficacy of a standardized perioperative pain management pathway and postoperative opioid requirements in men undergoing outpatient anterior urethroplasty at our institution. METHODS: Patients undergoing outpatient anterior urethroplasty by a single surgeon from August 2017 to January 2021 were prospectively followed. Standardized nonopioid pathways were implemented based on location (penile vs bulbar) and need for buccal mucosa graft. A practice change in October 2018 transitioned (1) from oxycodone to tramadol, a weak mu opioid receptor agonist, postoperatively and (2) from 0.25% bupivacaine to liposomal bupivacaine intraoperatively. Postoperative validated questionnaires included 72-hour pain level (Likert 0-10), pain management satisfaction (Likert 1-6), and opioid consumption. RESULTS: A total of 116 eligible men underwent outpatient anterior urethroplasty during the study period. One-third of patients did not use opioids postoperatively, and nearly 78% of patients used ≤5 tablets. The median number of unused tablets was 8 (IQR 5-10). The only predictor for use of >5 tablets was preoperative opioid use (75% vs 25%, P < .01). Overall, patients using tramadol postoperatively reported higher satisfaction (6 vs 5, P < .01) and greater percentages of pain reduction (80% vs 50%, P < .01) compared to those using oxycodone. CONCLUSIONS: For opioid-naïve men, 5 tablets or less of opioid medication with a nonopioid care pathway provides satisfactory pain control following outpatient urethral surgery without excessive overprescribing of narcotic medication. Overall, multimodal pain pathways and perioperative patient counseling should be optimized to further limit postoperative opioid prescribing.

Genitourinary Radiation Injury Following Prostate Cancer Treatment: Assessment of Cost and Health Care System Burden.

OBJECTIVE: To evaluate the healthcare resource impact of radiation injury following prostate cancer treatment. METHODS: Using IBM MarketScan, we performed a retrospective study of men with prostate cancer who were treated with radiotherapy and subsequently developed low-grade (LGRI) and high-grade radiation injury (HGRI). Radiation injury diagnoses included bladder neck stenosis, hematuria/cystitis, fistula, ureteral stricture, and incontinence. LGRI and HGRI included injury diagnosis without intervention and with intervention, respectively. Health care visits and costs were measured over 5 time periods including 2 years before radiation, 1 year before radiation, radiation to injury diagnosis, injury diagnosis to first intervention (LGRI), and following first intervention (HGRI). Negative binomial regression modeling was used to assess the effect of radiation injury on average cost adjusting for demographics and comorbidities. RESULTS: Between 2008 and 2017, we identified 121,027 men who received radiotherapy following prostate cancer diagnosis of which 10,057 (8.3%) experienced a HGRI. The frequency of urologic visits and average costs were similar in those without injury and LGRI. However, men with HGRI experienced higher visit frequency and monthly costs. Amongst high-grade injuries, urinary fistula had the highest frequency of visit utilization at 378 visits before first intervention and 245 visits after first intervention. Following radiation injury diagnosis, the average monthly cost was twice as high in those with HGRI ($85.78) compared to LGRI ($38.66). CONCLUSIONS: HGRI was associated with increased urologic health care use and average monthly cost when compared to those who experienced LGRI or no injury. Urinary fistula was associated with the largest resource burden.

Incidence and Risk Factors for Postoperative Venous Thromboembolism After Gender Affirming Vaginoplasty: A Retrospective Analysis of a Large Insurance Claims Database.

OBJECTIVES: To investigate the incidence and associated risk factors of venous thromboembolism (VTE) after gender affirming vaginoplasty. METHODS: We searched International Business Machines Corporation (IBM) Marketscan, a commercial claims database, for Current Procedural Terminology and International Classification of Diseases (ICD) procedure codes to identify patients who underwent gender affirming vaginoplasty from 2011-2020. We quantified deep venous thrombosis and pulmonary embolism using ICD-9 and ICD-10 codes found within 90 days after surgery. Univariate and multivariate analyses were performed to establish association between VTE events and age, residency location, and comorbidities. RESULTS: We identified 1588 patients who underwent gender affirming vaginoplasty. Overall, 1.1% of patients experienced a VTE within 90 days following surgery. Patients who experienced postoperative VTE were older, more likely to have had a prior VTE, less likely to be from an urban area, and more likely to have a higher Charlson Comorbidity Index score. Among patients with postoperative VTE, 47.1% had previous VTE. Among patients without a postoperative VTE, 1.3% had previous VTE. CONCLUSION: In patients undergoing gender affirming vaginoplasty, the incidence of postoperative VTE was 1.1%. Older age, rurality, increased comorbidities, and prior VTE were associated with increased risk of postoperative VTE. Current guidelines do not recommend cessation of gender affirming hormone therapy (GAHT) prior to vaginoplasty. Further research is needed to evaluate if certain high-risk patients would benefit from perioperative adjustment of GAHT or perioperative VTE prophylaxis.

Patient Selection and Outcomes of Urinary Diversion.

Urinary diversion selection depends highly on surgeon experience, patient comorbidities, operative indication, and preoperative risk assessment. Navigating this process in the setting of emerging surgical approaches, new operative technology, and evolving perioperative care plans can be difficult for general and reconstructive urologists alike. In this article, we highlight considerations for urinary diversion selection and review new updates in the literature regarding preoperative patient assessment and nutrition optimization. In addition, we review unique perioperative considerations including role of preoperative bowel prep and intraoperative maneuvers in the setting of obesity and prior radiation. Last, we examine postoperative expectations, long-term outcomes, and emerging technology to mitigate postoperative risk associated with urinary diversions.

Robotic Urethral Reconstruction Outcomes in Men With Posterior Urethral Stenosis.

OBJECTIVE: To evaluate surgical outcomes stratified by posterior urethral obstruction (PUO) etiology in men undergoing definitive robotic posterior urethral reconstruction. MATERIALS AND METHODS: A retrospective, single surgeon, review of men undergoing robotic posterior urethral reconstruction between 2018 and 2020 was performed. Differences in complications, reconstructive success (no further intervention), and urinary continence by PUO etiology were assessed. RESULTS: Robotic posterior urethral reconstruction was performed in 21 men. PUO etiology included benign prostatic hypertrophy treatment in 5 (24%), prostatectomy in 10 (48%), radiation in 5 (24%), and trauma in 1 (5%). Median number of prior endoscopic treatments was 3 (benign prostatic hypertrophy), 3 (prostatectomy), and 2 (radiation) with an average time between obstruction and reconstruction of 9, 12, and 15 months (P = .52). Median length of stay after reconstruction was 2, 1, and 2 days (P = .45). Thirty-day complications occurred in 0%, 20%, 40% (P = .19). Post-reconstruction re-intervention was necessary in 0%, 10%, 80% (P = .004). Ultimately, anatomic success was achieved in 100%, 90%, 80% (P = .63), with functional success rates of 100%, 100%, 60% (P = .035). Median postoperative pad/day usage was 0,0, 10.5 (P <.001), and ultimately 0%, 30%, 80% (P = .013) underwent artificial urinary sphincter placement. CONCLUSION: Endoscopic treatment of posterior urethral obstruction (PUO) secondary to benign and malignant prostate conditions is associated with a high incidence of treatment failure. Robotic posterior urethral reconstruction is a safe and effective surgical solution for men with PUO in the absence of pelvic radiation. Men with pelvic radiation appear to be at increased risk of complications, PUO recurrence, and clinically significant stress urinary incontinence.

Robotic Puboprostatic Fistula Repair with Holmium Laser Pubic Debridement.

INTRODUCTION AND OBJECTIVE: Urosymphyseal fistula (UF) with osteomyelitis most commonly occurs as a result of prostate cancer and benign prostate hyperplasia therapy. UF presentation typically includes debilitating pelvic pain exacerbated with ambulation. Traditional management required open surgical genitourinary (GU) reconstruction with pubectomy leading to significant morbidity. However, progressive utilization of robotic approaches and advances in holmium laser technology has led to a less invasive alternative. Herein, we present our series of robotic-assisted holmium laser debridement of pubic osteomyelitis in the setting of UF. METHODS: After physical exam, all patients presenting with concerns for GU fistula and osteomyelitis are evaluated with BMP, CBC, serum albumin, urine culture, and cystoscopy. Patients often present with previously obtained CT abdomen/pelvis. However, all patients presenting with concerns of pubic osteomyelitis should undergo a MRI of the pelvis to characterize the pubis. Specific indications for holmium laser debridement of the pubic bone include: 1) history of sacral insufficiency fractures which eliminate management with partial pubectomy due to risk of pelvic ring instability and 2) mild osteomyelitis which can be managed with debridement. The patient is placed in dorsal lithotomy position. After the robot is docked, the space of retzius is developed and the fistula is resected down to the pubic bone. The symphysis is debrided using the Cobra grasper followed by holmium laser debridement at 2J and 50Hz settings. Appropriate GU reconstruction versus urinary diversion is then performed per clinical judgement. Antibiotic beads are then placed in the symphyseal defect. If available, an interposition flap may be advanced between the urethra/bladder and symphysis. RESULTS: In our series of four patients, all patients underwent successful robotic pubic symphyseal debridement and were discharged without experiencing a major complication. At follow up (7-16 months) there have been no fistula recurrence or recurrent episodes of osteomyelitis. CONCLUSION: Robotic assisted pubic symphyseal debridement with a holmium laser is feasible, safe, and efficacious in this small series with short follow up. This approach represents a minimally invasive alternative to open pubectomy while minimizing incisions and overall morbidity. Additional long-term data is necessary before wide spread adoption of this approach.

A Contemporary Analysis of Ureteral Reconstruction 30-Day Morbidity Utilizing the National Surgical Quality Improvement Program Database: Comparison of Minimally Invasive vs Open Approaches.

Objectives: To characterize 30-day morbidity of upper ureteral reconstruction (UUR) and lower ureteral reconstruction (LUR) surgery by comparing open and minimally invasive surgery (MIS) approaches using a national surgical outcomes registry. Methods: The American College of Surgeons National Surgical Quality Improvement Program database was reviewed for patients who underwent UUR and LUR between 2007 and 2017. Primary endpoints included 30-day complications, transfusion, readmission, return to operating room (ROR), and prolonged postoperative length of stay (LOS). Multivariable logistic regression was performed to observe the association of MIS approach on 30-day outcomes. Results: Three thousand forty-two patients were identified with 2116 undergoing UUR and 926 undergoing LUR. Of 2116 patients undergoing UUR, 1733 (82%) were performed through an MIS approach. On multivariable analysis, open approach for UUR was associated with increased odds of any 30-day complication (odds ratio (OR) 1.6 [1.1-2.4]; p = 0.014), major complication (OR 1.8 [1.04-3.0]; p = 0.034), transfusion (OR 3.7 [1.2-11.5]; p = 0.025), ROR (OR 2.0 [1.0-3.9]; p = 0.047), and prolonged LOS (OR 5.4 [3.9-7.6]; p < 0.001). Of the 926 patients undergoing LUR, 458 (49%) were performed through an MIS approach. On multivariable analysis, open approach for LUR was associated with increased odds of any 30-day complication (OR 1.5 [1.1-2.1]; p = 0.028), minor complication (OR 1.7 [1.1-2.6]; p = 0.02), transfusion (OR 8.1 [2.7-23.7]; p < 0.001), and prolonged LOS (OR 4.2 [2.4-7.3]; p < 0.001). Conclusion: Utilization of a national surgical database revealed an open approach was associated with increased 30-day morbidity across multiple postoperative outcome measures. These findings suggest an MIS approach should be considered, when feasible, for upper and lower ureteral reconstruction.

A comparison of artificial urinary sphincter outcomes after primary implantation and first revision surgery.

OBJECTIVE: The artificial urinary sphincter (AUS) is the gold standard for severe male stress urinary incontinence, though evaluations of specific predictors for device outcomes are sparse. We sought to compare outcomes between primary and revision AUS surgery for non-infectious failures. METHODS: We identified 2045 consecutive AUS surgeries at Mayo Clinic (Rochester, MN, USA) from 1983 to 2013. Of these, 1079 were primary AUS implantations and 281 were initial revision surgeries, which comprised our study group. Device survival rates, including overall and specific rates for device infection/erosion, urethral atrophy and mechanical failure, were compared between primary AUS placements versus revision surgeries. Patient follow-up was obtained through office examination, written correspondence, or telephone correspondence. RESULTS: During the study period, 1079 (79.3%) patients had a primary AUS placement and 281 (20.7%) patients underwent a first revision surgery for mechanical failure or urethral atrophy. Patients undergoing revision surgery were found to have adverse 1- and 5-year AUS device survival on Kaplan-Meier analysis, 90% vs. 85% and 74% vs. 61%, respectively (p<0.001). Specifically, revision surgery was associated with a significantly increased cumulative incidence of explantation for device infection/urethral erosion (4.2% vs. 7.5% at 1 year; p=0.02), with similar rates of repeat surgery for mechanical failure (p=0.43) and urethral atrophy (p=0.77). CONCLUSIONS: Our findings suggest a significantly higher rate of overall device failure following revision AUS surgery, which is likely secondary to an increased rate of infection/urethral erosion events.

Rectourethral Fistula Repair Using Robotic Transanal Minimally Invasive Surgery (TAMIS) Approach.

BACKGROUND: Small nonirradiated rectourethral fistula (RUF) without tissue necrosis or peri-fistula abscess are often treated via a trans-sphincteric or transperineal approach. Attempts at transanal rectal advancement flap to reduce associated morbidity have been widely abandoned due to poor visualization, inability to close the urethral defect in a watertight fashion, and compromise of rectal flap vascularity. Robotic transanal minimally invasive surgery (R-TAMIS) has emerged as a useful tool to address distal rectal lesions as it provides enhanced visualization and surgical dexterity. OBJECTIVE: Here we describe a novel R-TAMIS approach to address simple rectourethral fistula. METHODS: The patient is placed in prone jackknife position. An Applied Medical GelPOINT Path Transanal Access Platform is placed in the intra-anal position which is secured to a Lone Star retractor system. Three robotic trocars are placed as well as an AirSeal System to ensure adequate insufflation with suctioning. The fistula is dissected, and the rectum and urethra are separated. Following excision of the fistula tract, the urethra and rectum are closed independently with absorbable suture. RESULTS: In this initial series, both patients were discharged by post-operative day two. The Foley catheter was removed at 4 weeks. The repair was evaluated and intact via endoscopy at 3 months at time of diverting loop ileostomy reversal. No fistula recurrence or major morbidity occurred at a minimum follow up of 15 months. CONCLUSION: R-TAMIS provides an incisionless, minimally invasive reconstructive approach for well selected simple non-irradiated RUF. Additional data and long term follow up is needed before widespread application of this approach.

Narrative review of male urethral sling for post-prostatectomy stress incontinence: sling type, patient selection, and clinical applications.

Male stress urinary incontinence (SUI) following prostate treatment is a devastating complaint for many patients. While the artificial urinary sphincter is the gold standard treatment for male SUI, the urethral sling is also popular due to ease of placement, lack of mechanical complexity, and absence of manual dexterity requirement. A literature review was performed of male urethral sling articles spanning the last zz20 years using the PubMed search engine. Clinical practice guidelines were also reviewed for comparison. Four categories of male urethral sling were evaluated: the transobturator AdVance and AdVance XP, the bone-anchored InVance, the quadratic Virtue, and the adjustable sling series. Well selected patients with mild to moderate urinary incontinence and no prior history of radiation experienced the highest success rates at long-term follow up. Patients with post-prostatectomy climacturia also reported improvement in leakage after sling. Concurrent penile prosthesis and sling techniques were reviewed, with favorable short-term outcomes demonstrated. Male urethral sling is a user-friendly surgical procedure with durable long-term outcomes in carefully selected men with mild stress urinary incontinence. Multiple sling types are available with varying degrees of efficacy and complication rates. Longer follow-up and larger cohort sizes are needed for treatment of newer indications such as climacturia as well as techniques involving dual placement of sling and penile prosthesis.
