Short-term catheter management options for urinary retention following pelvic surgery: a cost analysis

Patient Removal of Urinary Catheters After Urogynecologic Surgery: A Randomized Controlled Trial

OBJECTIVE

To compare postoperative urinary retention rates in the early postoperative period between home and office catheter removal. Secondary outcomes included pain, difficulty, satisfaction, likelihood to use again, and health care utilization.

METHODS

We conducted a nonblinded, randomized controlled, noninferiority trial of women undergoing surgery for stress incontinence and prolapse from March 2021 to June 2022. Exclusion criteria were preoperative voiding dysfunction (need for self-catheterization or postvoid residual [PVR] greater than 150 mL), urethral bulking, and need for prolonged postoperative catheterization. Participants discharged with indwelling catheters because of an initial failed void trial were randomized 1:1 to home compared with office removal on postoperative day 3-4. For home removal, participants were instructed to remove the catheter at 7 am and to drink two glasses of water. If they had difficulty voiding 5 hours after catheter removal, they came to the office for a void trial. For office removal, participants returned for a backfill void trial with PVR assessment. Our primary outcome was rate of early postoperative urinary retention , defined as confirmed retention (PVR greater than half the voided volume) after catheter removal. Secondary outcomes were assessed at a 2-week call. Health care utilization (telephone calls and office visits) related to catheter issues was also assessed. At 80% power and α=0.05, we needed 100 participants (50/group) to detect a noninferiority margin of 11%.

RESULTS

Among 117 participants, the home (n=59) and office (n=58) removal groups were similar in mean age (60 years vs 61 years), mean body mass index (29 vs 30), pelvic organ prolapse quantification system stage 3 or 4, and proportion who underwent hysterectomy or apical suspension. Sling procedures were more common in the office group (45.8% vs 77.6%). For our primary outcome, the rate of early postoperative retention was 11.9% in the home group and 22.4% in the office group ( P =.13). Our predetermined noninferiority margin was greater than the upper bound of our 95% CI; thus, we conclude noninferiority of home removal. For secondary outcomes, the home removal group was more likely to report "no pain" ( P =.02) and "very likely" to use this method again ( P =.004). There were no differences in difficulty or satisfaction between groups. Number of nursing calls was not different ( P =.66); however, number of office visits was higher in the office group (median 0 [interquartile range 0-1] vs 1 [1-1], P <.001).

CONCLUSION

Postoperative urinary catheter removal by the patient at home was noninferior to office removal when early urinary retention rates were compared. Participants in the home removal group had fewer office visits and reported low pain, low difficulty, and high satisfaction.

Assessment of patient satisfaction with home vs office indwelling catheter removal placed for urinary retention after female pelvic floor surgery: a randomized controlled trial

BACKGROUND

Postoperative urinary retention is burdensome for patients. We seek to improve patient satisfaction with the voiding trial process.

OBJECTIVE

This study aimed to assess patient satisfaction with location of indwelling catheter removal placed for urinary retention after urogynecologic surgery.

STUDY DESIGN

All adult women who were diagnosed with urinary retention requiring postoperative indwelling catheter insertion after undergoing surgery for urinary incontinence and/or pelvic organ prolapse were eligible for this randomized controlled study. They were randomly assigned to catheter removal at home or in the office. Those who were randomized to home removal were taught how to remove the catheter before discharge, and were discharged home with written instructions, a voiding hat, and 10-mL syringe. All patients had their catheter removed 2 to 4 days after discharge. Those patients who were allocated to home removal were contacted in the afternoon by the office nurse. Subjects who graded their force of urine stream 5, on a scale of 0 to 10, were considered to have safely passed their voiding trial. For patients randomized to the office removal group, the voiding trial consisted of retrograde filling the bladder to maximum they could tolerate up to 300 mL. Urinating >50% of instilled volume was considered successful. Those who were unsuccessful in either group had catheter reinsertion or self-catheterization training in the office. The primary study outcome was patient satisfaction, measured based on patients' response to a question, "How satisfied were you with the overall removal process of the catheter?" A visual analogue scale was created to assess patient satisfaction and 4 secondary outcomes. A sample size of 40 participants per group were needed to detect a 10 mm difference in satisfaction between groups on the visual analogue scale. This calculation provided 80% power and an alpha of 0.05. The final number accounted for 10% loss to follow up. We compared the baseline characteristics, including urodynamic parameters, relevant perioperative indices, and patient satisfaction between the groups.

RESULTS

Of the 78 women enrolled in the study, 38 (48.7%) removed their catheter at home and 40 (51.3%) had an office visit for catheter removal. Median and interquartile range for age, vaginal parity, and body mass index were 60 (49-72) years, 2 (2-3), and 28 (24-32) kg/m2, respectively, in the overall sample. Groups did not differ significantly in age, vaginal parity, body mass index, previous surgical history, or type of concomitant procedures. Patient satisfaction was comparable between the groups, with a median score (interquartile range) of 95 (87-100) in the home catheter removal group and 95 (80-98) in the office catheter removal group (P=.52). Voiding trial pass rate was similar between women who underwent home (83.8%) vs office (72.5%) catheter removal (P=.23). No participants in either group had to emergently come into the office or hospital due to inadequate voiding afterwards. Within 30 days post operatively, a lower proportion of women in the home catheter removal group (8.3%) had urinary tract infection, compared to patients in the office catheter removal group (26.3%) (P=.04).

CONCLUSION

In women with urinary retention after urogynecologic surgery, there is no difference in satisfaction concerning the location of indwelling catheter removal when comparing home and office.

Risk Factors for Postoperative Urinary Retention Following Lumbar Spine Surgery: A Review of Current Literature and Meta-Analysis

STUDY DESIGN

Systematic Review and Meta-analysis.

OBJECTIVE

Postoperative urinary retention (POUR) is a common complication following lumbar spine surgery (LSS) and timely recognition is imperative to avoid long-term consequences. The aim of the current meta-analysis was to systematically review the literature in order to identify risk factors associated with POUR after LSS.

METHODS

In accordance with PRISMA guidelines, a systematic review of the literature was performed using Pubmed, EMBASE, and MEDLINE database for articles on POUR following LSS. A meta-analysis was performed comparing patients with and without POUR; and the factors associated with this adverse event were analyzed. The pooled data were reported as mean differences with 95% confidence intervals (CI; P < .05). Heterogeneity among the studies was evaluated using the I2 statistic.

RESULTS

The meta-analysis included 10 studies compromised of 30,300 patients. Based on our analysis, patients who were male, were older in age, underwent instrumented fusion, had diabetes mellitus, coronary artery disease, or benign prostatic hypertrophy had significantly higher risk of developing POUR. Additionally, patients in who developed POUR had significantly longer surgical times and higher volumes of intra-operative fluid administration, as compared with non-POUR patients. The POUR patients also had a significantly higher association with urinary tract infection. Prior surgery, BMI, length of stay, and smoking status did not reveal any statistical association with POUR.

CONCLUSIONS

Risk factors associated with POUR following LSS include male gender, older age, longer surgical times, fusion procedures, larger volumes of intraoperative infusions, and associated comorbidities like DM, CAD, and BPH.

Assessing Health Care Utilization and Feasibility of Transurethral Catheter Self-Discontinuation

OBJECTIVE

To compare the rates of health care utilization (office messages or calls, office visits, and emergency department [ED] visits) and postoperative complications within 30 days after surgery between patients with successful voiding trials on postoperative day 0 and those with unsuccessful voiding trials on postoperative day 0 and between patients with successful and unsuccessful voiding trials on postoperative day 1. Secondary objectives were to identify risk factors for unsuccessful voiding trials on postoperative days 0 and 1 and to explore the feasibility of catheter self-discontinuation by assessing for any complications associated with at-home catheter self-discontinuation on postoperative day 1.

METHODS

This study was a prospective observational cohort study of women undergoing outpatient urogynecologic or minimally invasive gynecologic surgery for benign indications at one academic practice from August 2021 to January 2022. Enrolled patients with unsuccessful immediate postoperative voiding trials on postoperative day 0 performed catheter self-discontinuation by cutting their catheter tubing per instructions at 6 am on postoperative day 1 and recording their voided volumes over the subsequent 6 hours. Patients who voided less than 150 mL underwent a repeat voiding trial in the office. Demographics, medical history, perioperative outcomes, and number of postoperative office calls or visits and ED visits within 30 days were collected.

RESULTS

Of the 140 patients who met inclusion criteria, 50 patients (35.7%) had unsuccessful voiding trials on postoperative day 0, and 48 of these 50 (96%) performed catheter self-discontinuation on postoperative day 1. Two patients did not perform catheter self-discontinuation on postoperative day 1: One had her catheter removed in the ED on postoperative day 0 during an ED visit for pain control, and the other performed catheter self-discontinuation off protocol at home on postoperative day 0. There were no adverse events associated with at-home postoperative day 1 catheter self-discontinuation. Of the 48 patients who performed catheter self-discontinuation on postoperative day 1, 81.3% (95% CI 68.1-89.8%) had successful postoperative day 1 at-home voiding trials, and 94.5% (95% CI 83.1-98.6%) of those with successful voiding trials did not require additional catheterization. Patients with unsuccessful postoperative day 0 voiding trials had more office calls and messages (3 vs 2, P <.001) and those with unsuccessful postoperative day 1 voiding trials attended more office visits (2 vs 1, P <.001) compared with those with successful postoperative day 0 or 1 voiding trials, respectively. There was no difference in ED visits or postoperative complications between patients with successful voiding trials on postoperative day 0 or 1 and those with unsuccessful voiding trials on postoperative day 0 or 1. Patients with unsuccessful postoperative day 0 voiding trials were older and more likely to have undergone vaginal hysterectomy or prolapse repair than those with successful postoperative day 0 voiding trials. Patients with unsuccessful postoperative day 1 voiding trials were older than those with successful postoperative day 1 voiding trials.

CONCLUSION

Catheter self-discontinuation is a feasible alternative to in-office voiding trials on postoperative day 1 after advanced benign gynecologic and urogynecologic surgery, with low rates of subsequent retention and no adverse events seen in our pilot study.
