OBJECTIVE: To identify the iatrogenic urethral stricture rate and elucidate potential predisposing risk factors for development of urethral stricture following Aquablation.
METHODS: We reviewed 170 patients that underwent Aquablation from February 2019 to September 2024. Postoperatively, a 22 Fr hematuria catheter was inserted and placed on traction with continuous bladder irrigation overnight. On postoperative day one, traction was removed, and irrigation was discontinued. If appropriate, patients underwent a void trial prior to discharge. Patients were seen for follow up at 6-week, 3-month, 9-month, and then yearly. The primary outcome was development of urethral stricture. Standard two-tailed t tests and Fisher's exact tests were used to assess for factors affecting stricture risk.
RESULTS: The postprocedural urethral stricture rate was 5.3% (9/170) with 89% in the fossa navicularis and one in the bulbar urethra. Mean stricture length was 1.9 cm (1.5-2.5). Mean traction time for stricture patients was 23.7 vs 18.1 hours in nonstricture patients (P < .001). Eighty nine percent of the stricture cohort was discharged home with a catheter, vs 47.8% in the nonstricture cohort (P = .01). The median indwelling catheter duration was 6.5days in stricture patients vs 1 day in the nonstricture patients (P < .03).
CONCLUSION: The incidence of symptomatic urethral stricture after Aquablation was 5.3% and associated with longer indwelling catheter duration and longer traction time.
