Resection of Pubic Symphysis and Cystectomy Significantly Improves Short-Term Patient-Reported Physical Functioning Among Patients With Pubovesical Fistula and Pubic Bone Osteomyelitis.

OBJECTIVE: To investigate the impact of extirpative surgery for pubic bone osteomyelitis with pubovesical fistula on prostate cancer survivors' physical and mental health. MATERIALS AND METHODS: The Short Form 12 (SF-12) is a validated instrument for assessing health-related quality of life (HRQOL). We reviewed a prospectively maintained database of patients treated with extirpative surgery for pubovesical fistula from 2017-2021 who completed the SF-12. Wilcoxon signed-rank and McNemar's tests were used to analyze changes in SF-12 following surgery. Narcotic prescriptions in the year before and after surgery were assessed as an additional measure of pain burden. RESULTS: Eighteen patients were included. Four had pre-operative SF-12s, 3 had post-operative SF-12s, and 11 had both. Median age was 76.5 years (IQR 71.75-80.00). All patients had previous radiation for prostate cancer. Compared to global pre-operative scores, post-operative physical composite scores (PCS) significantly increased (29.95 ± 8.59 vs 42.48 ± 7.18; P <.001), but mental composite scores (MCS) were similar (45.35 ± 9.98 vs 52.21 ± 8.23). When comparing individual, paired pre-operative and post-operative scores there was a significant improvement in PCS (30.56 ± 9.87 vs 45.45 ± 8.56; P = .005), but not MCS (47.49 ± 6.92 vs 51.60 ± 8.88). Median morphine milligram equivalent significantly decreased in the year post-surgery compared to the year prior (103.1, 33.0-250.9 vs 34.25, 0.0-105.9; P = .0008). CONCLUSION: For prostate cancer survivors with pubovesical fistula and pubic bone osteomyelitis, urinary diversion with pubic bone resection improves physical functioning and decreases narcotic prescriptions without untoward effects on mental health.
