We report our 6-year experience in women following prolapse repair. METHODS We identified 592 women who underwent anterior and/or apical prolapse repair at our institution from 2009 to 2015 and reviewed the records of 266 women with preoperative UDS evaluation. Primary outcome was postoperative voiding efficiency (VE = voided volume ÷ capacity) and/or post void residual (PVR) after surgery. Data were analyzed in SAS using repeated measure mixed effects models to assess within and between group changes over time. RESULTS All 266 women (mean age 61 years) had preoperative UDS tracing, surgical and follow-up data available for analysis. There were 519 PVRs recorded at up to 2,949 days (mean 364, σ=639) and 9 time points (median 2, IQR 1-3) after surgery. Preoperative UDS revealed a mean: [email protected] 22 cmH2O (IQR 12-30), Qmax 18 mL/s (IQR 11-23), capacity 529 mL (IQR 370-659), PVR 120 mL (IQR 5-160). Women with prolapse [POP-Q Stage: I (n=14), II (n=120), III (n=118), IV (n=14)] underwent anterior-only (n=115), apical-only (n=41) or combination anterior-apical (n=110) prolapse repair. Using mixed effects models, significant UDS cutpoints associated with worsening postoperative PVR and/or VE over time were identified: BCI < 60 (11% reduction VE, p<0.05), capacity > 600 mL (59 mL higher PVR, p=0.01); preoperative PVR > 200 mL (93 mL higher PVR, p<0.01; 8% reduction VE, p<0.05). The Qmax < 10 mL/s cutpoint approached significance (7% reduction VE, p=0.053). Sling placement was associated with a 49 mL higher PVR (ref 99 mL, p<0.05) and non-significant 5% lower VE (ref 82%, p=0.058). High grade (Stage III or IV) prolapse was paradoxically associated with 6% higher VE (ref 78%, p<0.05). Urinary tract infections (n=120) were associated with a 77 mL higher PVR (ref 78 mL, p<0.01) and 13% reduction in VE (ref 86%, p<0.01). Factors not significantly predictive of worse PVR and/or VE include: all BOOI and [email protected] cutpoints, anterior versus apical repair, diabetes (n=37, p=0.92), hyperlipidemia (n=91, p=0.08), neuropathy (n=17, p=0.33), and obesity (n=44, p=0.76). CONCLUSIONS BOOI and [email protected] are poorly predictive of VE and/or PVR following prolapse surgery. Women with a BCI < 60, capacity > 600 mL or PVR > 200 mL are at risk of worsening VE and/or PVR following prolapse repair and should be considered for earlier pBOO intervention. © 2018FiguresReferencesRelatedDetails Volume 199Issue 4SApril 2018Page: e433 Advertisement Copyright & Permissions© 2018MetricsAuthor Information Amy D.
