RESUMO

PURPOSE: The treatment of urethral stenosis after a combination of prostatectomy and radiation therapy for prostate cancer is understudied. We evaluate the clinical and patient-related outcomes after dorsal onlay buccal mucosal graft urethroplasty (D-BMGU) in men who underwent prostatectomy and radiation therapy. MATERIALS AND METHODS: A multi-institutional, retrospective review of men with vesicourethral anastomotic stenosis or bulbomembranous urethral stricture disease after radical prostatectomy and radiation therapy from 8 institutions between 2013 to 2021 was performed. The primary outcomes were stenosis recurrence and development of de novo stress urinary incontinence. Secondary outcomes were surgical complications, changes in voiding, and patient-reported satisfaction. RESULTS: Forty-five men were treated with D-BMGU for stenosis following prostatectomy and radiation. There was a total of 7 recurrences. Median follow-up in patients without recurrence was 21 months (IQR 12-24). There were no incidents of de novo incontinence, 28 patients were incontinent pre- and postoperatively, and of the 6 patients managed with suprapubic catheter preoperatively, 4 were continent after repair. Following repair, men had significant improvement in postvoid residual, uroflow, International Prostate Symptom Score, and International Prostate Symptom Score quality-of-life domain. Overall satisfaction was +2 or better in 86.6% of men on the Global Response Assessment. CONCLUSIONS: D-BMGU is a safe, feasible, and effective technique in patients with urethral stenosis after a combination of prostatectomy and radiation therapy. Although our findings suggest this technique may result in lower rates of de novo urinary incontinence compared to conventional urethral transection and excision techniques, head-to-head comparisons are needed.

RESUMO

OBJECTIVE: To outline our step-by-step surgical technique for a transurethral ventral buccal mucosa graft inlay urethroplasty to treat fossa navicularis and distal urethral strictures. METHODS: The transurethral ventral inlay urethroplasty is accomplished in four steps. First, after obtaining proper exposure the cicatrice is excised via a transurethral ventral urethrotomy until the lumen is at least 24fr. Second, double arm 6-0 polydioxanone suture is used to deliver the triangular buccal mucosal graft to the proximal extent of the urethrotomy and secured externally. Third, the graft is secured to the meatus with 5-0 polyglactin sutures and additional 6-0 double arm polydioxanone sutures are used to quilt the graft for spread fixation. Finally, a 16fr silicone catheter is placed. Patients are discharged the same day and return for void trial after one week. A retrospective, single institution review was conducted to include all patients who underwent this procedure with a minimum of 1 year follow-up. Patients were analyzed for recurrences, and pre- and post-operative urine flow rates, post void residuals, and patient questionnaires were also reviewed. RESULTS: 44 patients met our inclusion criteria. Median surgical time was 120 minutes. At a mean follow up of 36 months (IQR 22-50) 95% of patients are patent without additional interventions. The 2 patients that did have stricture recurrence were found to have urethral stenosis that extended more proximally, and both were successfully treated with a dorsal onlay buccal urethroplasty. There were significant improvements in urine flow rate, post void residuals, international prostate symptom score and quality of life scores post operatively. There was no difference in post operative sexual function scores. CONCLUSION: This minimally invasive transurethral ventral urethroplasty has excellent intermediate term outcomes in terms of traditional objective measures of urethroplasty success and patient reported outcomes.

RESUMO

AIMS: Transmasculine genital reconstructive surgery involves the creation of a neourethra by way of metoidioplasty or phalloplasty. We aim to describe approaches in identifying complications associated with these procedures as well as the various reparative techniques that can be utilized to reestablish the neourethral tract. METHODS: We prepared a guide to diagnostic and procedural interventions for urologic complications following transmasculine genital reconstructive surgery based on our clinical experience as well as those of our colleagues. We reviewed all current peer-reviewed publications based on this topic. RESULTS: These procedures have a considerable revision rate for urologic complications, which include urethrocutaneous fistulae, persistent vaginal remnant, and urethral strictures. These complications often present simultaneously and require appropriate workup and treatment. CONCLUSIONS: Several reconstructive techniques can be employed to restore the neourethral tract, as we describe in detail.

RESUMO

OBJECTIVE: To outline our step-by-step surgical technique using a subcoronal buccal mucosal graft (BMG) resurfacing technique for the treatment of recurrent penile adhesions. METHODS: To perform the 'buccal belt' procedure a subcoronal circumferential segment of diseased skin was excised. An appropriately sized BMG was circumferentially secured subcoronally with a proximal and distal anastomosis to the edges of the wound. Quilting stitches were also placed to allow proper graft fixation. A petroleum jelly bolster was secured as a tie-over dressing. Patients were discharged with a Foley catheter and the bolster dressing in place. The bolster and Foley catheter were removed 7 days postoperatively. The patients were then seen for follow-up at 4- to 6-month intervals. A retrospective, international multi-institutional review was conducted to include all patients who underwent this procedure. Surgical complications, evidence of recurrence, and patient-reported outcome measures including visual analogue scale (VAS) and global response assessment (GRA) questionnaires were reviewed. RESULTS: Thirty-one men underwent the procedure across six institutions between March 2014 and September 2020. The mean (range) surgical time was 59 (25-95) min. At the mean (range) follow-up of 27 (4-79) months all patients reported resolution of presenting symptoms and no recurrence of adhesions. The mean VAS score was 8.9 and 9.0 for aesthetics and functional outcomes, respectively. On GRA, overall improvement was reported by all patients (61%, +3; 25%, +2; 14%, +1). CONCLUSION: There are limited options for the treatment of recurrent penile adhesions. A subcoronal BMG resurfacing is feasible, with no recurrence and overall high satisfaction seen in an initial patient cohort.

RESUMO

OBJECTIVES: Penile urethral stricture disease not associated with hypospadias is rare, and there is a wide range of commonly used surgical repair techniques for this disease. We sought to compile a multi-institutional database of patients who had surgical correction of strictures in the penile urethra not limited to the meatus, and who had no history of hypospadias, for analysis using the Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology classification system. METHODS: A retrospective database from 13 institutions was compiled of patients who had undergone surgical correction of Trauma and Urologic Reconstructive Network of Surgeons length, urethral segment and etiology urethral stricture segments S2b/S2c and excluding E5, with a minimum follow-up time of 4 months. Failure was defined as cystoscopically confirmed recurrence of a stricture measuring less than 16-Fr. RESULTS: We analyzed 222 patients with a median age of 57 years and a follow-up of 49 months. The overall surgical success rate was 80.2%. On multivariate analysis, the two variables identified that were predictive of surgical success were stricture length ≤2 cm as well as use of a buccal mucosa graft as compared to use of a fasciocutaneous flap, which had success rates of 83% and 52%, respectively (P = 0.0004). No statistically significant differences were found based on incisional approach or surgical technique, nor were outcomes different based on etiology or preoperative patient demographics. CONCLUSIONS: Surgical repair of penile urethral strictures of non-hypospadiac origin have a favorable overall success rate, at 80.2%. Regardless of incisional approach or surgical technique, all operations appear to have similar outcomes other than repairs using fasciocutaneous flap, which were statistically less successful than those using buccal mucosa graft.

RESUMO

PURPOSE: To critically evaluate a multi-institutional patient cohort undergoing Dorsal-Onlay Buccal Mucosal Graft Urethroplasty (D-BMGU) for recurrent post-radiation posterior urethral stenosis. METHODS: Retrospective multi-institutional review of patients with posterior urethral stenosis from 10 institutions between 2010-2019 was performed. Patients with at least 1-year follow-up were assessed. Patient demographics, stenosis characteristics, peri-operative outcomes, and post-operative clinical and patient-reported outcomes were analyzed. The primary outcomes were stenosis recurrence and de-novo stress urinary incontinence (SUI). Secondary outcomes were changes in voiding, sexual function, and patient-reported satisfaction. RESULTS: Seventy-nine men with post-radiation urethral stenosis treated with D-BMGU met inclusion criteria. Median age and stenosis length were 72 years, (IQR 66-75), and 3.0 cm (IQR 2.5-4 cm), respectively. Radiation modalities included: 36 (45.6%) external beam radiotherapy (EBRT), 13 (16.5%) brachytherapy (BT), 10 (12.7%) combination EBRT/BT, and 20 (25.3%) EBRT/radical prostatectomy. At a median follow-up of 21 months (IQR 13-40), 14 patients (17.7%) had stenosis recurrence. Among 37 preoperatively-continent patients, 3 men (8.1%) developed de-novo SUI following dorsal onlay urethroplasty. Of 29 patients with preoperative SUI all but one remained incontinent post-operatively (96.6%). Following repair, patients experienced significant improvement in PVR (92.5 to 26 cc, p = 0.001) and Uroflow (4.6 to 15.9 cc/s, p = 0.001), and high overall satisfaction, with 91.9% reporting a GRA of + 2 or better). CONCLUSION: Dorsal onlay buccal mucosa graft urethroplasty is a safe and feasible technique in patients with post-radiation posterior urethral stenosis. This non-transecting approach may confer low rates of de-novo SUI. Further research is needed to compare this technique with excisional urethroplasty.

RESUMO

PURPOSE: To validate a novel method of urethral stricture treatment using liquid buccal mucosal grafts (LBMG) to augment direct vision internal urethrotomy (DVIU) in an animal model. MATERIALS AND METHODS: A rabbit stricture model was used to test this method. Strictures were induced in 26 rabbits using electroresection of urethral epithelium. The animals were randomized into two groups: Group-1, treated with DVIU and LBMG in fibrin glue, and Group-2, DVIU with fibrin glue only. LBMG was prepared by suspension of mechanically minced buccal mucosa micrografts in fibrin glue. This LBMG-fibrin glue mixture was later injected into the urethrotomies of Group-1 animals. All animals were killed at 24 weeks after repeat retrograde urethrogram (RUG) and urethroscopy by surgeon blinded to the treatment arm. Radiographic images and histological specimens were reviewed by a radiologist and a pathologist, respectively, blinded to the treatment arm. Stricture treatment was considered a success if a diameter measured on RUG increased by ≥ 50% compared to pre-treatment RUG diameter. Histological specimens were assessed for the presence of BMG engraftment. RESULTS: In Group-1, 8/12(67%) animals demonstrated engraftment of LBMG, compared to none in Group-2 (p = 0.0005). 7/12(58%) in Group-1 showed radiographic resolution/improvement of strictures compared to 5/13 Group-2 rabbits (38%, p = 0.145). The median percent change for the Group-1 was 59%, compared to 41.6% for Group-2 (p = 0.29). CONCLUSION: This proof-of-concept study demonstrates feasibility of LBMG for endoscopic urethral stricture repairs. Further studies are needed to establish the role of this novel concept in treatment of urethral strictures.

RESUMO

PURPOSE: To critically evaluate a multi-institutional patient cohort undergoing single-stage distal urethral repair using a novel transurethral buccal mucosa graft inlay urethroplasty technique (TBMGI). METHODS: A retrospective multi-institutional review of consecutive patients with fossa navicularis (FN) strictures treated with a single-stage TBMGI technique at 12 institutions from March 2014-March 2018 was performed. Patient demographics, stricture characteristics, clinical and patient-reported outcomes were analyzed. The primary outcomes were stricture recurrence and complications. Secondary outcomes were change in maximum urinary flow rate (Qmax), PVR, and changes in IPSS, SHIM and global response assessment (GRA) questionnaire responses. Descriptive statistical analysis was used for evaluation of outcomes. RESULTS: Sixty-eight men met inclusion criteria. Median age and stricture length were 60 years (IQR 48-69) and 2 cm (IQR 2-3), respectively. Most common stricture etiology was lichen sclerosus (34%). Median operative time and EBL were 72 min (IQR 50-120) and 20 mL (IQR 10-43), respectively. Fifty-seven men completed ≥ 12-month follow-up. At a median follow-up of 17 months (IQR 13-22), 54 patients (95%) remained stricture-free. Median Qmax improved from 5 to 18 mL/s (p < 0.0001), PVR 76-21 mL (p < 0.0001), and IPSS 15-5 (p < 0.0001); IPSS-QOL score: 5-1 (p < 0.0001). SHIM score did not significantly change following repair (median 22-21 p = 0.85). On GRA assessment, a majority of men reported "marked" (64%) or "moderate" (28%) overall improvement. No patient developed fistula, glanular dehiscence, graft necrosis or chordee. CONCLUSIONS: This novel minimally invasive transurethral urethroplasty technique is feasible and has demonstrated generalizable outcomes in a multi-institutional cohort with varying etiologies.

RESUMO

INTRODUCTION: Repair of post-TURP sphincter urethral strictures represents challenging problem, due to the risk of urinary incontinence after the repair. We described a surgical technique we use to repair these strictures preserving urinary continence in patients with incompetent bladder neck. MATERIALS AND METHODS: An observational, retrospective, study was conducted to include patients with post-TURP urethral strictures in the area of distal sphincter. We included only patients with complete clinical data and follow-up who previously underwent TURP or HOLEP or TUIP, and subsequently developed proximal bulbar urethral strictures close to the membranous urethra and the related distal urethral sphincter. Patients were included, if they were fully continent after TURP or other procedures to treat BPH. The primary outcome of the study was treatment failure, defined as the need for any post-operative instrumentation. Secondary outcome was post-urethroplasty urinary continence. Patients showing stricture recurrence or post-operative incontinence were classified as failure. RESULTS: Overall, 69 patients were included in the study. Median patient's age was 67 years; median stricture length was 4 cm. Thirty-tree patients (47.8%) underwent previous urethrotomy. Median follow-up was 52 months. Out of 69 patients, 55 (79.7%) were classified as success and 14 (20.3%) as failure. Out of the whole cohort, thus, 11/69 (16%) have a risk of recurrent strictures and 3/69 (4.3%) have incontinence. CONCLUSIONS: The use of modified ventral onlay graft urethroplasty, using particular non-aggressive steps, is a suitable surgical technique for repair of sphincter urethral stricture in patients who underwent BPH transurethral surgery, using different procedures (TURP, HOLEP, TUIP).

RESUMO

PURPOSE OF REVIEW: Urethral reconstruction has evolved in the last several decades with the introduction of various techniques including fasciocutaneous skin flaps and buccal mucosal grafts. However, distal urethral strictures have continued to be a reconstructive challenge due to tendency for adverse cosmetic outcomes, risks of glans dehiscence or fistula formation, and stricture recurrence. RECENT FINDINGS: The surgical options for treatment of distal urethral strictures have changed throughout the years; however, there is no one universally accepted technique for their treatment. The current trend for treatment is shifting away from multi-staged procedures or the use of local skin flaps to single-stage transurethral procedures that utilize buccal mucosa with glans preservation. This chapter will describe the evolution of distal urethral stricture treatments tracking gradual improvements and modifications over time. The different interventions include transurethral approaches, such as dilations and visual urethrotomy, meatotomy, and meatoplasty/urethroplasty techniques including genital skin flaps and single- and double-stage repairs with buccal mucosal grafts.

RESUMO

PURPOSE OF REVIEW: Due to the proximity of the rhabdosphincter and cavernous nerves to the membranous urethra, reconstruction of membranous urethral stricture implies a risk of urinary incontinence and erectile dysfunction. To avoid these complications, endoscopic management of membranous urethral strictures is traditionally favored, and bulboprostatic anastomosis is reserved as the main classical approach for open reconstruction of recalcitrant membranous urethral stricture. The preference for the anastomotic urethroplasty among reconstructive urologists is likely influenced by the familiarity and experience with trauma-related injuries. We review the literature focusing on the anatomy of membranous urethra and on the evolution of treatments for membranous urethral strictures. RECENT FINDINGS: Non-traumatic strictures affecting bulbomembranous urethra are typically sequelae of instrumentation, transurethral resection of the prostate, prostate cancer treatment, and pelvic irradiation. Being a different entity from trauma-related injuries where urethra is not in continuity, a new understanding of membranous urethral anatomy is necessary for the development of novel reconstruction techniques. Although efficacious and durable to achieve urethral patency, classical bulboprostatic anastomosis carries a risk of de-novo incontinence and impotence. Newer and relatively less invasive reconstructive alternatives include bulbar vessel-sparing intra-sphincteric bulboprostatic anastomosis and buccal mucosa graft augmented membranous urethroplasty techniques. The accumulated experience with these techniques is relatively scarce, but several published series present promising results. These approaches are especially indicated in patients with previous transurethral resection of the prostate in which sparing of rhabdosphincter and the cavernous nerves is important in attempt to preserve continence and potency. Additionally, introduction of buccal mucosa onlay grafts could be especially beneficial in radiation-induced strictures to avoid transection of the sphincter in continent patients, and to preserve the blood supply to the urethra for incontinent patients who will require artificial urinary sphincter placement. The evidence regarding erectile functional outcomes is less solid and this item should be furtherly investigated.

RESUMO

PURPOSE: We evaluated urinary and erectile functional outcomes after dorsal onlay urethroplasty for bulbomembranous urethral strictures. Our aim was to understand the functional implications of dissection of the posterior urethra. MATERIALS AND METHODS: We report on men who underwent membranous urethral stricture repair by buccal mucosal graft dorsal onlay substitution urethroplasty. Continence and erectile function were assessed preoperatively and postoperatively. Tissue routinely excised from the intercrural space during dissection of the dorsal aspect of the membranous urethra was evaluated for scar, striated muscle and nerves. RESULTS: A total of 16 consecutive men with a mean age of 48.3 years (range 26 to 72) who had strictures with a mean length of 56 mm (range 15 to 170) involving the membranous urethra were included in analysis. Of the 16 men 15 were continent preoperatively and remained continent postoperatively. Three of 10 men (30%) with a preoperative SHIM (Sexual Health Inventory for Men) score of 17 to 25 had a decrease after urethroplasty. All 16 men had an improved maximum urinary flow rate with a mean improvement of 22 ml per second. I-PSS (International Prostate Symptom Score) improved from a median of 23 to 4 postoperatively with a median bother score improvement of 5 to 0. Histopathological assessment identified striated muscle and nerves in 6 (46%) and 9 (69%) of 13 specimens. Overall nerves and muscle comprised an average of less than 15% of the specimen. CONCLUSIONS: The dorsal onlay technique with a buccal mucosal graft for membranous urethral stricture repair does not compromise continence or erectile function in most patients. Dissection at the level of the membranous urethra should be limited because striated muscle and cavernous nerves are present.

RESUMO

PURPOSE: We describe a novel method of urethral stricture treatment using liquid buccal mucosal grafts to augment direct vision internal urethrotomy. MATERIALS AND METHODS: A rabbit stricture model was used to test this method. In phase 1 the concept of endoscopic liquid buccal mucosal graft implantation was tested by performing direct vision internal urethrotomy in 3 rabbits with immediate intraurethral injection of autologous liquid buccal mucosal grafts suspended in fibrin glue. Animals were sacrificed at 2 to 3 weeks and the urethras were examined for the presence of buccal mucosa engraftment. In phase 2 strictures were induced by electroresection in 9 rabbits divided into 2 groups, including 1) 6 rabbits treated with direct vision internal urethrotomy and liquid buccal mucosal grafts, and 2) 3 controls that underwent direct vision internal urethrotomy and injection of fibrin glue only. Two treated and 1 control animals were sacrificed at 8, 16 and 24 weeks each. Prior to sacrifice the animals underwent retrograde urethrograms and urethroscopy. Histological specimens were examined for the presence of buccal mucosal engraftment. RESULTS: In phase 1, 2 of the 3 rabbits demonstrated engraftment of buccal mucosa in the urethra after injection of liquid buccal mucosal grafts. In phase 2 all 6 treated animals demonstrated engraftment with resolution/improvement of strictures on retrograde urethrograms and urethroscopy. Controls had no buccal engraftment and showed fibrosis and chronic inflammation. One of the 3 controls had persistent stricture on retrograde urethrograms and cystoscopy. CONCLUSIONS: This proof of concept study demonstrated the feasibility of using liquid buccal mucosal grafts for endoscopic urethral stricture repair. Such a method may allow for wide application of this novel concept of using liquid buccal mucosal grafts to augment direct vision internal urethrotomy.

RESUMO

BACKGROUND: Urologic complications in genital gender-affirming surgery are imperfectly measured, with existing evidence limited by "blind spots" that will not be resolved through implementation of patient-reported outcomes alone. Some blind spots are expected in a surgical field with rapidly expanding techniques, and they may be exacerbated by factors related to transgender health. METHODS: The authors provide a narrative review of systematic reviews published in the past decade to describe the current options for genital gender-affirming surgery and surgeon-reported complications, as well as contrasting peer-reviewed sources with data not reported by the primary surgeon. In combination with expert opinion, these findings help estimate complication rates. RESULTS: Eight systematic reviews describe complications in patients undergoing vaginoplasty, including 5% to 16.3% mean incidence of meatal stenosis and 7% to 14.3% mean incidence of vaginal stenosis. Compared with surgeon-reported cohorts, patients undergoing vaginoplasty or vulvoplasty in other reports had higher rates of voiding dysfunction (47% to 66% versus 5.6% to 33%), incontinence (23% to 33% versus 4% to 19.3%), or misdirected urinary stream (33% to 55% versus 9.5% to 33%). Outcomes in six reviews of phalloplasty and metoidioplasty included urinary fistula (14% to 25%), urethral stricture or meatal stenosis (8% to 12.2%), and ability to stand to void (73% to 99%). Higher rates of fistula (39.5% to 56.4%) and stricture (31.8% to 65.5%) were observed in alternate cohorts, along with previously unreported complications such as vaginal remnant requiring reoperation. CONCLUSIONS: The literature does not completely describe urologic complications of genital gender-affirming surgery. In addition to standardized, robustly validated patient-reported outcome measures, future research on surgeon-reported complications would benefit from using the IDEAL (idea, development, exploration, assessment, and long-term study) framework for surgical innovation.

RESUMO

INTRODUCTION AND HYPOTHESIS: We present our management of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling using a novel combination of surgical techniques including total or near total mesh excision, urinary tract reconstruction, and concomitant pubovaginal sling with autologous rectus fascia in a single operation. METHODS: We retrospectively reviewed the medical records of 189 patients undergoing transvaginal removal of polypropylene mesh from the lower urinary tract or vagina. The focus of this study is 21 patients with LUT mesh perforation after mid-urethral polypropylene mesh sling. We excluded patients with LUT mesh perforation from prolapse kits (n = 4) or sutures (n = 11), or mesh that was removed because of isolated vaginal wall exposure without concomitant LUT perforation (n = 164). RESULTS: Twenty-one patients underwent surgical removal of mesh through a transvaginal approach or combined transvaginal/abdominal approaches. The location of the perforation was the urethra in 14 and the bladder in 7. The mean follow-up was 22 months. There were no major intraoperative complications. All patients had complete resolution of the mesh complication and the primary symptom. Of the patients with urethral perforation, continence was achieved in 10 out of 14 (71.5 %). Of the patients with bladder perforation, continence was achieved in all 7. CONCLUSIONS: Total or near total removal of lower urinary tract (LUT) mesh perforation after mid-urethral polypropylene mesh sling can completely resolve LUT mesh perforation in a single operation. A concomitant pubovaginal sling can be safely performed in efforts to treat existing SUI or avoid future surgery for SUI.

RESUMO

INTRODUCTION AND HYPOTHESIS: We compared the operative and immediate postoperative experience of the trocar-based Prolift and non-trocar-based Elevate techniques used to repair vaginal prolapse. METHODS: A retrospective review of Prolift and Elevate repairs was performed. Baseline characteristics and operative and postoperative variables evaluated included compartment(s) repaired, adjacent organ injury, operative time (OT), change in hemoglobin (ΔH), pain score, narcotic use, length of stay (LOS), and short-term complications. Categorical variables were assessed as counts and percent frequency. Data were compared using chi-squared analysis and paired t test. RESULTS: Prolift (n = 143) and Elevate (n = 77) patients were similar in age (p = 0.19). Concurrent hysterectomy was done in 22 (15.4 %) and 24 (31.2 %), respectively, and concurrent midurethral sling placed in 100 (70 %) and 50 (65 %), respectively. LOS (median, 25th,75th) after anterior/apical compartment repairs was shorter with Elevate, whether with (1.0; 1.0,1.5 vs. 2.0 days;1.0, 2.0; p = 0.003) or without (2.0; 1.0, 2.0 vs. 2.0 days; 2.0, 3.0; p = 0.024) hysterectomy, but no differences in OT, ΔH, pain score, or narcotic use occurred. Posterior compartment mean pain scores were lower with Prolift (3.6 ± 2.2 vs. 1.7 ± 1.5, p = 0.035), and three-compartment-repair pain scores were lower with Elevate (0.6 ± 1.3 vs 2.5 ± 1.9; p = 0.013). Three bladder injuries occurred with Prolift but none with Elevate. CONCLUSIONS: Operative and postoperative experiences were similar between groups; however, Elevate anterior/apical repairs had shorter LOS, which might reflect more aggressive discharge planning. There were no bowel or major vascular injuries, and the Prolift trocar bladder injuries did not alter the surgical procedure.
