AbstractObjectiveTo compare perioperative costs and morbidity between open and robotic sacrocolpopexy after implementation of enhanced recovery after surgery (ERAS) pathway.MethodsThe present retrospective cohort study of patients undergoing open or robotic sacrocolpopexy (January 1, 2014, through November 30, 2017) used an ERAS protocol with liposomal bupivacaine infiltration of laparotomy incisions. Primary outcomes were costs associated with index surgery and hospitalization, determined with Medicare cost‐to‐charge ratios and reimbursement rates and adjusted for variables expected to impact costs. Secondary outcomes included narcotic use, length of stay (LOS), and complications from index hospitalization to postoperative day 30.ResultsFor the total of 231 patients (open cohort, 90; robotic cohort, 141), the adjusted mean cost of robotic surgery was $3239 higher compared with open sacrocolpopexy (95% confidence interval [CI] $1331–$5147; P < 0.001). Rates were not significantly different for intraoperative complications (robotic, 4.3% [6/141]; open, 5.6% [5/90]; P = 0.754), 30‐day postoperative complications (robotic, 11.4% [16/141]; open, 16.7% [15/90]; P = 0.322), or readmissions (robotic, 5.7% [8/141]; open, 3.3% [3/90]; P = 0.535). The percentage of patients dismissed on postoperative day 1 was greater in the robotic group (89.4% [126/141] vs. 48.9% [44/90], P < 0.001).ConclusionsDecreased LOS associated with ERAS provided significant cost savings with open sacrocolpopexy versus robotic sacrocolpopexy without adverse impacts on perioperative complications or readmissions.

INTRODUCTION: In younger men, in whom organic prostate disease is uncommon, the etiology of lower urinary tract symptoms (LUTS) is frequently unclear. Studies suggest that in this young cohort voiding phase dysfunction is more common than storage phase dysfunction or normal urodynamics. Abnormal pelvic floor muscle relaxation, which can result in constipation, could potentially result in voiding dysfunction also. To date, no studies have investigated the relationship between posterior pelvic floor dysfunction and LUTS in young men. METHODS: Men who had undergone both anorectal manometry and uroflowmetry (i.e. had lower gastrointestinal and urinary symptoms) between October 2012 and September 2018 were identified. Patients >40 years old were excluded to reduce the likelihood of prostate disease. Clinical data was extracted from the electronic health records. Descriptive and comparative analyses were performed. RESULTS: Of 47 identified patients, 13 were excluded due to a history of neurogenic bowel/bladder, urethral/anal surgery or significant neurological disease. The mean age and standard deviation (SD) of the 34 men analyzed was 30 ± 6 years. Twenty patients demonstrated an abnormal balloon expulsion test (BET). The median (and interquartile range [IQR]) number of LUTS was 1.5 (1-2). An abnormal BET was not associated with symptoms of nocturia, hesitancy, incomplete emptying or the total number of LUTS (2 vs 1, P = 0.6). An abnormal balloon expulsion test was associated with a lower maximum urinary flow rate (Qmax, 14 vs 29 mls/sec, P < 0.001) but not flow duration (34 vs. 27 seconds, P = 0.2), residual urine volume (55 vs. 43 mls, P = 0.7) or urine volume (300 vs. 301 mls, P = 0.5). No correlation was seen between anal pressures at rest or during simulated evacuation and maximum urinary flow rate. No correlation was found between functional constipation and Qmax, LUTS or abnormal uroflow. No relationship between rectal sensory thresholds and urinary symptoms was identified. CONCLUSION: In this study of young men undergoing both anorectal manometry and uroflow, pelvic floor dysfunction was not associated with specific LUTS but was associated with a clinically significant reduction in maximum urinary flow rate. However an objective diagnosis of functional constipation was not associated with urologic abnormalities. Further studies will be needed to prospectively characterize this cohort and to identify whether PFD-associated LUTS and reduced flow respond to biofeedback therapy.

Objective The objective of the study was to evaluate the utility of urodynamic studies performed before primary midurethral sling placement for stress urinary incontinence in predicting the need for subsequent sling release for voiding dysfunction. Methods The health records of women managed with primary synthetic midurethral sling placement at Mayo Clinic (Rochester, MN) from January 1, 2002, to December 31, 2012, were reviewed. The primary outcome was surgical sling release for postoperative voiding dysfunction (ie, prolonged retention, elevated postvoid residual volumes with new voiding symptoms, or de novo onset or worsening of overactive bladder symptoms). Logistic regression models were used to evaluate associations between potential clinical risk factors and the primary outcome. Results Overall, 1629 women underwent primary synthetic midurethral sling placement during the study time frame, including 1081 patients (66%) who underwent a preoperative multichannel urodynamic evaluation. A sling release for voiding dysfunction was performed for 51 patients (3.1%) at a median of 1.9 months postoperatively (interquartile range, 1.3–9.3 months). Patients undergoing sling release were significantly more likely to have had retropubic sling placement (P = 0.003) and concomitant prolapse surgery (P = 0.005). On univariate analysis, no urodynamic parameters were associated with the risk of sling release; evaluated parameters included peak flow rate (P = 0.20), postvoid residual volume (P = 0.37), voiding without detrusor contraction (P = 0.96), and detrusor pressure at maximal flow (P = 0.23). Conclusions Sling release for voiding dysfunction was rare in our cohort. No urodynamic parameters were associated with the risk of sling release.

Objectives To determine the rate of perioperative complications and cost associated with Mayo-McCall culdoplasty (MMC), open abdominal sacrocolpopexy (ASC), and robotic sacrocolpopexy (RSC) for posthysterectomy vaginal vault prolapse. Methods We retrospectively searched for the records of patients undergoing posthysterectomy apical vaginal prolapse surgery (MMC, ASC, or RSC) between January 1, 2000, and June 30, 2012, at our institution. For all patients identified, perioperative complications, length of hospital stay, and inpatient costs to patients were abstracted from the medical records and compared by procedure. Inverse–probability-of-procedure weighting using propensity scores was used to obtain less-biased comparisons of outcomes between procedures. Results A total of 512 patients met the inclusion criteria (174 MMC, 237 ASC, and 101 RSC). Using inverse-probability weighting, the MMC group had a significantly lower intraoperative complication rate (3.3% vs 11.6% for ASC, 3.4% vs 24.1% for RSC), median operative time (94 vs 217 min for ASC, 100 vs 228 min for RSC), and median cost (US $8,776 vs $12,695 for ASC, US $8,773 vs $13,107 for RSC) than the ASC and RSC groups (all P < 0.01). In addition, the MMC group had significantly fewer postoperative grade 3+ complications than the RSC group (1.1% vs 9.4%, P < 0.01). Conclusions In the treatment of posthysterectomy vaginal vault prolapse, MMC is associated with decreased non–urinary tract infection, less perioperative morbidity, and lower cost to patients compared with sacrocolpopexy.

Objective The optimal suture selection for mesh attachment during robotic sacrocolpopexy (RSC) is currently unknown. Here, we sought to evaluate the outcomes of RSC using absorbable sutures for vaginal and sacral mesh attachment. Methods We retrospectively reviewed 132 RSC surgeries that were performed for vaginal vault prolapse in the Division of Gynecologic Surgery at our institution from February 2007 to December 2013. All cases were performed with absorbable suture (polyglactin) for vaginal and sacral mesh fixation. Sacrocolpopexy failure was defined as patients undergoing either repeat prolapse surgery or pessary use for recurrent prolapse. The durability of RSC was assessed via Kaplan-Meier method. Results The median age at surgery was 61.1 years (interquartile range [IQR], 55.6–68.2) and the median length of postoperative follow-up was 33 months (IQR, 15.7–57). The median body mass index was 26.5 kg/m2 (IQR, 24.3–29.7). During follow-up, 10 patients underwent prolapse retreatment. There were 2 apical recurrences, 4 distal anterior recurrences, 2 posterior recurrences, and, in 2 cases, the location was unknown. One apical recurrence was confirmed to be secondary to detachment of the mesh from the sacral promontory. Among those with recurrence, the median time to recurrence was 15.5 months (IQR, 4.22–35.9). Overall, the 1-year and 3-year freedom from repeat surgery rates were 96% and 93%, respectively. Conclusions With a median follow-up of 33 months, the use of absorbable suture for both vaginal and sacral attachments during RSC is effective. Further studies evaluating suture selection and mesh attachment techniques for RSC are needed.

Introduction and Hypothesis To report on clinical presentation, diagnosis, and outcomes after treatment of female urethral diverticulum (UD). Methods Using a record linkage system, women with a new diagnosis of UD at Mayo Clinic from January 1, 1980, through December 31, 2011, were identified. The presenting symptoms, clinical characteristics, diagnosis, and management of women presenting with UD were recorded. Outcomes after surgery were assessed using survival analysis. All statistical analyses were 2-sided and P values less than 0.05 were considered significant. Statistical analysis was done using SAS version 9.2 and JMP version 9.0 (SAS Institute Inc.). Results A total of 164 cases were identified. Median age at diagnosis was 46 years (range, 21–83). The most common presenting symptom was recurrent urinary tract infection (98, 59.8%), followed by urinary incontinence (81, 49.4%), dysuria (62, 37.8%), dyspareunia (37, 22.6%), and hematuria (15, 9.1%). Examination revealed vaginal mass in 55 (33.5%) of the women. A significant trend was noted toward an increase in use of both magnetic resonance imaging and computed tomography (P < 0.001) along with a progressive decrease in use of urethrogram (P < 0.001) for diagnosis of UD over the years. Among 114 women who underwent surgical treatment for UD, 14(12.3%) women presented with recurrent UD and the 5-year recurrence rate after surgery for UD was 23.4% (95% confidence interval, 13.9–37.0) and a reoperation rate of 17.0% (95% confidence interval, 8.8–30.2) at 5 years. Conclusions Female UD is a rare and unique condition. Clinical presentation is usually nonspecific, and magnetic resonance imaging is commonly used for confirming the diagnosis. Recurrence is not uncommon, and repeat surgical intervention might be needed.
