Abstract PDF PubReader ePub: Background
In this study, we report 1-year follow-up clinical results of prostate artery embolization (PAE) in patients with glandular hematuria or acute urinary retention caused by a large prostate (over 100 mL).
Methods
Twenty-one consecutive patients undergoing PAE from March 2018 to July 2020 were included in this retrospective study. Clinical follow-up was conducted for all patients 1, 3, 6, and 12 months after the procedure. The outcome measures included the International Prostate Symptom Score (IPSS), quality of life (QoL), peak urinary flow rate (Qmax), post-void residual (PVR), prostate volume, prostate-specific antigen, and complications. A p-value <0.05 was considered statistically significant.
Results
Twenty-one patients with severe benign prostatic hyperplasia (BPH) with acute urinary retention or prostatic hematuria were enrolled in this study. Technical success rate was 90.5% (19/21), and unilateral PAE was done in 2/21 (9.5%) patients by pelvic vascular obliteration. In all patients, the mean IPSS, QoL score, Qmax, and PVR were significantly improved at 12 months post-PAE. The mean IPSS decreased from 26.1 to 12.1 points (p<0.05), mean QoL score decreased from 4.6 to 2.9 points (p<0.05), mean Qmax increased from 2.1 to 9.4 mL/s (p<0.05), and mean PVR decreased from 300.0 to 70.7 mL (p<0.05). The catheter was successfully removed from 19/21 patients and clinical success rate was 90.5%.
Conclusions
PAE was an effective and safe treatment option for patients with BPH and very large prostates (>100 mL) and urinary retention or gross hematuria associated with BPH in men unfit for surgery.

Abstract PDF PubReader ePub: Background
The principle of treatment for a vesicovaginal fistula (VVF) tract is complete removal of the fistula tract and surrounding scar tissue, followed by anastomosis without tension from surrounding healthy tissue. We present our novel two-step procedure for VVF repair.
Methods
We retrospectively analyzed 12 women, aged 14 to 67 years, who were treated between 2011 and December 2018. Conservative treatments failed, as these patients had complex VVFs. This technique consisted of two steps: first, transurethral resection of the fistula tract and surrounding scar tissue; second, transvaginal repair of the bladder mucosa, bladder muscle, and vaginal mucosa with tensionless anastomosis. If an interposition flap was needed, we used a Martius flap.
Results
The mean operation time was 186.3 minutes (range, 145–320 minutes), and the mean urethral catheter indwelling time was 10 days. Ten patients successfully underwent surgery through a transvaginal approach with no intraoperative or postoperative complications. However, one patient developed peritoneal perforation during transurethral resection of the fistula due to severe granulation tissue formation around the fistula, which prompted conversion to an abdominal approach. In two cases, we used a Martius flap because of the poor tissue condition due to previous radiation therapy and an inflammatory reaction. At a mean follow-up of 37 months (range, 16–51 months), no recurrence of VVF was observed in any patients.
Conclusions
This novel technique for transurethral VVF tract resection followed by transvaginal fistula repair was very safe and effective technique, and this straightforward technique is expected to reduce surgeons’ burden.
