RESUMEN

PURPOSE: To assess the incidence of artificial urinary sphincter (AUS) explant in high-risk patients and to evaluate the relationship between transcorporal cuff (TCC) placement and explant risk in this population. METHODS: We retrospectively reviewed all AUS insertions performed on high-risk patients by a single surgeon from 2010 to 2020. "High-risk" was defined as having ≥ 1 urethral risk factor: pelvic radiation, urethroplasty, recalcitrant urethral/bladder neck stenosis, urethral stenting, or previous AUS erosion/infection. Patients with ≥ 2 factors were "ultra-high-risk." Time-to-event analyses were used to assess all-cause-, infection/erosion-related-, and mechanical failure-related explant-free survival. Subgroup analyses were performed for patients with a history of radiation and urethral dissection. RESULTS: The final cohort included 68 men, mean age of 67 years (SD 11), and 77 AUS cuffs. Mean follow-up was 32 months (IQR 6-50). 29% of cuffs (n = 22) were transcorporal. 32 cuffs (42%) were explanted. All-cause explant-free survival was 64% at 1 year and 52% at 2 years. Classification as "ultra-high-risk" was not associated with explant risk (all p-values > 0.05). TCC placement was associated with an increased risk of explant for infection/erosion across all patients (HR 2.74, p = 0.03) and in radiated patients (n = 50; HR 4.1, p = 0.04), but not in patients with prior urethral dissection (n = 52; HR 1.98, p = 0.21). CONCLUSION: High-risk patients have a high rate of AUS explant and TCC placement may not be protective in this population. TCC placement was associated with an increased risk of infection/erosion in radiated patients, but not in those with a history of open urethral surgery.

RESUMEN

OBJECTIVE: To compare the histological properties and stretch of colorectal mucosal grafts (CMG) and buccal mucosal grafts (BMG) and to evaluate the impact of age, medical comorbidity and tobacco use on these metrics. MATERIALS AND METHODS: Samples of BMGs from patients undergoing augmentation urethroplasty were sent for pathologic review. CMGs were collected from patients undergoing elective colectomy. CMGs were harvested fresh, at full thickness from normal rectum/sigmoid. Patients with inflammatory bowel disease, prior radiation, or chemotherapy were excluded. RESULTS: Seventy two BMGs and 53 CMGs were reviewed. While BMGs and CMGs were both histologically composed of mucosal (epithelium + lamina propria) and submucosal layers, the mucosal layer in CMG had crypts. The outer epithelial layers differed significantly in mean thickness (BMG 573µm vs. CMG 430µm, p=0.0001). Mean lamina propria thickness and submucosal layer thickness also differed significantly (BMG 135µm vs. CMG 400µm, p<0.0001; BMG 1090µm vs. CMG 808µm, p = 0.007, respectively). Mean delta stretch, as to length and width, was greater for CMG (118% x 72%) compared to BMGs (22% x 8%), both p<0.001. CONCLUSION: CMGs and BMGs significantly differ histologically in layer composition, width and architecture, as well as graft stretch. Given its elastic properties, CMG may be useful in covering large surface areas, but its thin epithelium, thick lamina propria and additional muscularis mucosal layer could impact graft take and contracture.

RESUMEN

PURPOSE: We evaluated if scores generated by the LSE classification system and the Urethral Stricture Score system are associated with intraoperative surgical complexity and stricture recurrence risk. MATERIALS AND METHODS: We retrospectively reviewed all consenting patients who underwent single-stage anterior urethroplasty by a single surgeon at 2 institutions. Urethral Stricture Score and a numerical LSE "score" was calculated for each patient. Pearson's correlation and linear regression analyses were used to assess for a relationship between increasing Urethral Stricture Score and LSE score and surgical complexity. Kaplan-Meier curves and Cox proportional hazard regression models were used to assess for an association between Urethral Stricture Score and LSE score and stricture recurrence risk. RESULTS: A total of 187 patients with a mean age of 48 years (SD 16) and mean stricture length of 4.2 cm (SD 3.3) were included. Mean follow-up was 21 months. Forty-six patients recurred over time. We found a strong positive linear correlation between Urethral Stricture Score and LSE score (P < .001). Both increasing Urethral Stricture Score and LSE score independently linearly correlated with increasing surgical complexity (both P < .0001). Univariable analysis demonstrated that increasing LSE score was significantly associated with an increased risk of stricture recurrence (HR 1.2, P = .02) but Urethral Stricture Score was not. Patients with a high LSE score (≥7) were nearly 3 times as likely to recur versus patients with a low LSE score (HR 2.7, P = .001). CONCLUSIONS: Increasing Urethral Stricture Score and LSE score are both associated with increasing surgical complexity, but only LSE score is associated with stricture recurrence risk. Conversion of the LSE classification system into a numeric score adds functionality to this novel system.

RESUMEN

PURPOSE: The Optilume® drug-coated balloon (DCB) is a urethral dilation balloon with a paclitaxel coating that combines mechanical dilation for immediate symptomatic relief with local drug delivery to maintain urethral patency. The ROBUST III study is a randomized, single-blind trial evaluating the safety and efficacy of the Optilume DCB against endoscopic management of recurrent anterior urethral strictures. MATERIALS AND METHODS: Eligible patients were adult males with anterior strictures ≤12Fr in diameter and ≤3 cm in length, at least 2 prior endoscopic treatments, International Prostate Symptom Score ≥11 and maximum flow rate <15 ml per second. A total of 127 subjects were enrolled at 22 sites. The primary study end point was anatomical success (≥14Fr by cystoscopy or calibration) at 6 months. Key secondary end points included freedom from repeat treatment, International Prostatic Symptom Score and peak flow rate. The primary safety end point included freedom from serious device- or procedure-related complications. RESULTS: Baseline characteristics were similar between groups, with subjects having an average of 3.6 prior treatments and average length of 1.7 cm. Anatomical success for Optilume DCB was significantly higher than control at 6 months (75% vs 27%, p <0.001). Freedom from repeat intervention was significantly higher in the Optilume DCB arm. Immediate symptom and urinary flow rate improvement was significant in both groups, with the benefit being more durable in the Optilume DCB group. The most frequent adverse events included urinary tract infection, post-procedural hematuria and dysuria. CONCLUSIONS: The results of this randomized controlled trial support that Optilume is safe and superior to standard direct vision internal urethrotomy/dilation for the treatment of recurrent anterior urethral strictures <3 cm in length. The Optilume DCB may serve as an important alternative for men who have had an unsuccessful direct vision internal urethrotomy/dilation but want to avoid or delay urethroplasty.

RESUMEN

PURPOSE: Performing 1-stage urethroplasty in patients with urethral strictures caused by lichen sclerosus (LS) is hotly debated among reconstructive urologists due to conflicting reports of success. Therefore, the objective of this study was to determine the pooled incidence of stricture recurrence following 1-stage buccal mucosal graft (BMG) urethroplasty in patients with LS, to determine the impact of surgical technique on recurrence and to compare recurrence risk between patients with and without LS after 1-stage repairs. MATERIALS AND METHODS: A systematic review was conducted in accordance with PRISMA criteria. The primary outcome was pooled incidence of recurrence, which was calculated using a Der-Simonian-Laird binary random effects model with a Freeman-Tukey arcsine transformation. A total of 21 studies were included, of which 15 provided data for comparative analyses. RESULTS: Pooled data from 625 LS patients revealed a stricture recurrence rate of 10% (95% CI 6-14). Among studies with longer followup (≥24 months), this increased to 18%. Among patients with penile urethral involvement, studies utilizing a penile skin incision had significantly higher pooled recurrence rates than those utilizing penile invagination (p=0.004). Across all studies, there was no evidence to suggest a difference in pooled recurrence rate between patients with and without LS (p=0.36). However, across only long-term studies, recurrence risk was significantly higher for patients with LS (OR 1.83, p=0.05). CONCLUSIONS: One-stage BMG urethroplasty is likely a viable surgical option for patients with LS-related strictures; however, high-quality data are limited. Future multi-institutional, long-term prospective studies are needed to assess durability of 1-stage repair.

RESUMEN

PURPOSE: We utilized the National Trauma Data Bank® database to report practice patterns in managing blunt traumatic ureteral injuries and assess the consistency with current guidelines/literature. MATERIALS AND METHODS: Between 2007 and 2016 all National Trauma Data Bank database patients with blunt traumatic ureteral injuries were identified using ICD-9 and Abbreviated Injury Scale codes. Penetrating trauma and missing data were excluded. Patients were unstable if Injury Severity Score was above 15 or systolic blood pressure was 90 mmHg or less. Abbreviated Injury Scale severity score 2 or less was a low severity ureteral injury. Treatment options were minimally invasive methods or ureteral reconstruction. Patients who underwent laparotomy for associated injuries were identified. Chi-square, Fisher exact or 2-tailed t-test was utilized to evaluate differences. Univariable logistic regression identified independent variables that favored a specific treatment. RESULTS: A total of 147 blunt traumatic ureteral injuries were used for analysis. Of the patients 98 (66.7%) were unstable and 51 (34.7%) had a high severity ureteral injury. Patients with low and high severity ureteral injuries were treated more frequently with minimally invasive methods over ureteral reconstruction. Laparotomy for associated injuries resulted in a higher frequency of ureteral reconstruction (15 of 55, 27.3%) vs laparotomy for ureteral reconstruction alone (9 of 55, 16.4%; p=0.0012). On univariable analysis patients who underwent exploratory laparotomy or underwent an associated injury repair that facilitated retroperitoneal exploration had significantly higher odds of receiving ureteral reconstruction over minimally invasive methods. CONCLUSIONS: Contrary to guidelines, practice patterns favor treating severe blunt traumatic ureteral injuries with minimally invasive methods over ureteral reconstruction. Ureteral reconstruction is favored when patients undergo laparotomy for associated injuries.

RESUMEN

PURPOSE: Previous studies have elucidated the unique macroscopic and histological properties of buccal mucosa that make it a viable and durable graft for urethral augmentation. However, no prior literature has directly investigated the impact of preoperative oral health on these features. MATERIALS AND METHODS: We analyzed all consenting patients who underwent buccal mucosal graft (BMG) urethroplasty at our institution from 2018 to 2020. Validated oral health surveys, the Oral Health Impact Profile (OHIP-14) and the Kayser-Jones Brief Oral Health Status Examination (BOHSE) were completed preoperatively. A staff pathologist analyzed BMG histology and quantified oral mucositis using a modified Oral Mucosa Rating Scale. RESULTS: We analyzed 51 patients with a median age of 40 years (IQR 31-58). Mean BOHSE score was 1.1 and OHIP-14 score was 1.4. Median epithelial thickness was 530 µm and lamina propria thickness was 150 µm. On age-adjusted analysis, increasing BOHSE and OHIP-14 were associated with decreasing epithelial thickness (p values <0.05). Higher BOHSE scores also correlated with thinner lamina proprias (p=0.05) and increased graft stretch (p=0.03). The 2 patients with postoperative urine leaks and available graft histology had lamina propria thicknesses well below the cohort median, at 50 µm and 60 µm. CONCLUSIONS: This is the first study to demonstrate that oral health conditions impact graft histology and stretch. Although much remains to be learned, our findings shed light on the potential importance of optimizing oral health prior to BMG urethroplasty, and raise the question of if preoperative mucosal biopsy could help inform surgical decision making and discussions regarding surgical success.

RESUMEN

BACKGROUND: Female sexual dysfunction (FSD) after pelvic fracture (PFx) has garnered little attention in the urology literature. AIM: To review and summarize the current evidence regarding female PFx-related sexual function. METHODS: We performed a systematic review in accordance with PRISMA guidelines, including PubMed, EMBASE, and MEDLINE. We included only English-language manuscripts and abstracts with sufficient data for inclusion. We used the search terms "female sexual dysfunction AND pelvic fracture," "sexual dysfunction AND pelvic fracture," and "female pelvic fracture AND sexual dysfunction." A total of 177 articles were identified; 41 abstracts were reviewed; of which, 19 manuscripts were reviewed. Fifteen met inclusion criteria for analysis. OUTCOMES: The main outcome measures of this study are rates and types of female sexual dysfunction after pelvic fracture. RESULTS: FSD is prevalent after PFx, with reported rates between 25% and 62%. Three studies used the validated Female Sexual Function Index. The other 12 used non-validated questionnaires or adapted quality-of-life questionnaires with specific questions regarding FSD. The most common complaints include difficulty with intercourse, dyspareunia, orgasmic dysfunction, genitourinary pain, decreased interest in intercourse, decreased satisfaction with intercourse, and pelvic floor dysfunction. Only 1 study addressed resolution of dysfunction (30 of 98 patients [30.4%]). CLINICAL IMPLICATIONS: FSD is prevalent and an under-recognized sequela of pelvic fracture. This requires future prospective study to better characterize sexual dysfunction and identify effective treatments in trauma survivors. STRENGTH AND LIMITATIONS: To Increase awareness of FSD after pelvic trauma and the impact on the quality of life in trauma survivors. The current literature is limited by a lack of standardized assessment of FSD, limited follow-up, and minimal discussion of treatment options, in addition to the inherent bias of retrospective studies. CONCLUSIONS: FSD after traumatic PFx is not uncommon, occurs mostly in young women, and can be morbid. FSD after PFx is underreported in the urology literature. Thus, all female PFx patients should be screened for FSD by validated questionnaires. The published literature offers little knowledge as to the epidemiology, evaluation, definition, and potential treatments of FSD after PFx. Prospective studies are needed to better understand female sexual function in trauma survivors and the potential methods for prevention and rehabilitation, all within the context of a multidisciplinary approach.

RESUMEN

PURPOSE OF REVIEW: This article reviews the mechanisms, risk factors, evaluation and current management options for iatrogenic lower urinary tract stenosis, including urethral stricture and bladder neck contracture, caused by surgery for benign prostatic hyperplasia (BPH). RECENT FINDINGS: The incidence of iatrogenic stenosis following endoscopic BPH surgery ranges from 0 to 9.7%. New endoscopic techniques and technologies for treating BPH do not appear to substantially mitigate this risk. However, new advances in our understanding of urethral sphincter anatomy combined with both innovative open urethroplasty techniques and utilization of robotic surgery for bladder neck reconstruction, offer promise in improving treatment outcomes for this patient population. Treating patient with stenosis following BPH-related surgery can be challenging, especially in patients with recurrent disease. Optimizing outcomes and patient satisfaction relies on performing a thorough work-up and openly discussing treatment choices, risks and postoperative expectations with patients. Future research and emerging technology in both endoscopic BPH treatment surgical options and management of postoperative stenosis is critical to continuing to improve patient care.

RESUMEN

OBJECTIVE: The objective is to summarize and characterize the long-term success of anterior augmentation urethroplasty (AU) in published series. The current literature on AU consists largely of retrospective series reporting intermediate follow-up and incompletely characterize the long term outcomes of AU. MATERIALS AND METHODS: A systematic literature review was performed consistent with PRISMA guidelines to characterize long-term outcomes of AU with a minimum upper limit follow-up of 100 months. Penile/preputial skin flaps and graft and oral mucosal graft urethroplasties were included. The primary outcome was stricture-free survival for one-stage AU. Secondary analysis evaluated differences in outcomes based on two failure definitions: the need for intervention versus presence of recurrent stricture on cystoscopy or urethrography. Hazard rates were induced from the reported failure rates of one-stage AU and fixed and random effect models were fitted to the data. Additional subset analysis, removing potential confounders (lichen sclerosus, hypospadias and penile skin graft), was performed. RESULTS: Ten studies met inclusion criteria, and two studies reported separate outcomes for grafts and flaps, and thus were included separately in the analysis. The mean hazard rate across all studies was 0.0044, the corresponding survival rates at 1 year 0.948, 5 years 0.766, 10 years 0.587, and 15 years 0.45. Subset analysis of the 4 select and homogeneous studies noted 1, 5, 10, and 15 years survival rates of 0.97, 0.96, 0.74, and 0.63, respectively. CONCLUSIONS: The long-term success rates of augmentation urethroplasty are appear to be worse than previously appreciated and patients should be counseled accordingly.

RESUMEN

PURPOSE: Hysterectomy (Hys) is the most common non-urologic surgery associated with iatrogenic genitourinary (GU) injury. We present the largest known population-based evaluation of GU injury related to benign Hys. METHODS: The New York Statewide Planning and Research Cooperative System (SPARCS) was queried by ICD-9 and CPT codes. SPARCS for women from 1995 to 2014, who underwent laparoscopic or robotic Hys (minimally invasive surgery = MIS), abdominal Hys (AH), and vaginal Hys (VH) for benign diagnoses. Bladder and ureteral repairs were captured based on the procedure codes. Codes for ureteroneocystotomy (UNC) were compared to any other ureteral repairs, to elucidate injury patterns. Statistical analysis was conducted using Chi squared test, ANOVA, Mann-Whitney test and Poisson Regression and multivariable analysis were performed. RESULTS: 516,340 women underwent Hys for a benign etiology. 69% were AH, 25% VH, and 6% were MIS. 7490 patients (1.45%) had a concomitant GU injury. Compared to VH, MIS and AH were associated with greater odds of bladder and ureteral injury (p < 0.001). MIS and AH, compared to VH, were associated with reduced odds of UNC compared to complex reconstruction (OR 0.27, p < 0.001 and OR 0.12, p < 0.00, respectively). The injured cohort had higher total mean charges ($29,889 vs $15,808) and length of hospitalization (6.32 vs 3.56 days) (p < 0.001). CONCLUSIONS: Bladder and ureteral injuries during hysterectomy are uncommon in contemporary practice and are lower than historical rates. GU injury increases hospitalization cost. VH is associated with the lowest rate of GU injury, and thus appears to be a valuable approach, when feasible.

RESUMEN

INTRODUCTION: To evaluate flexible pediatric cystoscopy (FPC) as an adjunctive procedure to retrograde urethrography (RUG) and voiding cystourethrography (VCUG) in the preoperative setting for male urethral strictures. Since imaging interpretation of stricture length and caliber can be difficult at times, we sought to evaluate diagnostic utility of FPC to predict reconstructive surgery. MATERIALS AND METHODS: Reconstructive urology databases at Washington University and Columbia University were queried from 2010-2017. A total of 185 anterior urethroplasty patients met inclusion criteria. All surgeries were performed by a single surgeon. There were 102 patients that underwent preoperative FPC (7.5 Fr in diameter). Surgical urethroplasty techniques employed were: ventral or dorsal onlay buccal mucosa graft, fasciocutaneous penile skin flap, excision and primary anastomosis or augmented anastomotic. We analyzed the RUG, VCUG, FPC, and intraoperative details of the urethral strictures by univariate and multivariate statistics. RESULTS: Mean patient age was 47.2 (+/-16.5) years. Of the patients who underwent FPC, 42.2% were narrower than the FPC, and 57.8% were wider. Intraoperative stricture length better correlated with FPC findings compared to RUG/ VCUG (r = 0.834 versus r = 0.766) (p < 0.001). Moreover, inability to pass the FPC through the stricture correlated with the need to perform urethral stricture excision or complete reconstruction of the urethral plate (p = 0.005), rather than onlay urethroplasty. CONCLUSION: Preoperative FPC is a useful adjunctive tool in the evaluation of urethral strictures. FPC facilitates stricture assessment by accurately correlating with intraoperative stricture length and predicting the need to excise or graft during reconstruction.

RESUMEN

PURPOSE: There are sparse data directly comparing the probability of renal injury in children and adults. The kidney of the child is believed to be more susceptible to blunt injury for a variety of anatomical reasons. In a large cohort we tested the hypothesis that the pediatric kidney is more susceptible to any renal injury and to higher grade injury. MATERIALS AND METHODS: We queried the NTDB® (National Trauma Data Bank®) on all hospital admissions following motor vehicle collisions in a pediatric population (age less than 21 years) and a referent adult population (age 30 to 50 years). Of 111,172 children who were admitted after motor vehicle collisions 1,093 had renal injury. RESULTS: Of the 111,172 children admitted to the hospital following motor vehicle collisions 59,385 had abdominal trauma and 1,093 had renal injury. In a multivariate logistic model adjusting for overall ISS (Injury Severity Score), region, year, driver/passenger status, presence of restraint or an airbag, we found that children had 48% higher odds of renal injury compared to adults ages 30 to 50 years (OR 1.48, 95% CI 1.32-1.66, p <0.001). Furthermore, children were at 33% higher risk for high grade renal injury (OR 1.33, 95% CI 1.05-1.69, p = 0.919). The effect remained when restricting analysis to patients with concomitant liver and spleen injuries (p <0.001). CONCLUSIONS: In a large national cohort of children, blunt renal injury following motor vehicle collisions is rare but substantially more common than in adults. The odds of high grade renal injury are approximately 50% higher in children. A greater index of suspicion and a lower threshold for renal imaging is prudent for children with blunt abdominal trauma from motor vehicle collisions.

RESUMEN

PURPOSE: The primary goal of urinary fistulae repair is to improve continence and quality of life. Irradiated patients are predisposed to development of bladder outlet dysfunction (BOD), defined as bladder neck contracture or stress urinary incontinence. Here, we review our experience with gracilis flap repairs for rectourinary fistulae (RUF) and urinary cutaneous fistulae (UCF) in patients who underwent pelvic radiation. METHODS: Twenty-seven patients underwent repair of a RUF/UCF with gracilis flap between 2003 and 2013. Patients were assessed for postoperative fistula closure and BOD, and quality of life was assessed with the Expanded Prostate Index Composite (EPIC) questionnaire administered via telephone at the time of final follow-up. RESULTS: Mean age was 60 years (50-73) with median follow-up of 28.7 months (1.0-128). Flap failure was noted in 5/20 radiated patients versus 3/7 non-radiated patients (p = 0.63). Of the 8 flap failures, 7 underwent secondary repair: repeat gracilis flap (2), coloanal pull-through (2), rectal advancement flap (1), sliding flap (1), and omental flap (1). Median time to revision was 7.2 months (3.5-24.9). In irradiated patients, 18/20 (90 %) developed BOD compared with 1/7 (14 %) who were not radiated (p = 0.0006). Radiation was associated with worse scores on the urinary incontinence domain of the EPIC questionnaire compared with non-radiated patients (p = 0.0458). CONCLUSIONS: Urinary fistula repairs in radiated patients should be undertaken with caution. Even if the fistula is successfully repaired, patients may still have bladder outlet dysfunction and decreased quality of life. Consequently, patients should be counseled about all possible procedures, including permanent urinary diversion as primary therapy.

RESUMEN

INTRODUCTION: We sought to examine the role of advanced age (defined as >70 years), impaired cognitive function, and decreased manual dexterity in the rates of re-operation (revision or replacement) of artificial urinary sphincters (AUS). METHODS: From 1988 to 2012, 213 men underwent virgin AUS placements. Failure was defined as a revision performed for stress incontinence and replacement/exploration performed for urethral erosion/infection or mechanical failure. Kaplan-Meier curves were constructed to compare failure rates with age and Cox proportional hazard models were used to test associations. RESULTS: Advanced age was not associated with overall failure (p = 0.48), erosion/infection failure (p = 0.65), recurrent/persistent incontinence failure (p = 0.08), or mechanical failure (p = 0.36). Controlling for age, patients with cognitive dysfunction or decreased manual dexterity showed a higher rate of overall failure (p = 0.01). CONCLUSIONS: AUS placement is an excellent option to treat stress urinary incontinence in elderly men with intact cognition and good manual dexterity. AUS placement should be performed with caution in patients with impaired cognitive function or decreased manual dexterity, and additional effort should be made to identify these conditions both before and after surgery.
