The Feasibility, Technique, and Medium-Term Follow-Up of Laparoscopic Transvesical Diverticulectomy

Abstract

<b><i>Background:</i></b> To present our experience and results with the transvesical laparoscopic diverticulectomy, developed by Pansadoro et al. [<i>BJU Int</i>. 2009;103(3):412–24], as treatment of symptomatic bladder diverticula, with a medium-term follow-up. <b><i>Methods:</i></b> Between June 2010 and July 2018, we successfully operated 15 patients (13 male/2 female), aged 32–85 years (mean age 61 years) in 2 centers in Austria, using the aforementioned technique. <b><i>Results:</i></b> The median operative time was 297 min (range 83–488 min), and the blood loss was minimal. The median diameter of the diverticula was 94 mm (range 40–110 mm). The transurethral catheter was removed in most patients on day 7 (range 1–26 days), and cystography was performed before catheter removal. Patients were discharged on the ninth postoperative day (range 4–18 days). One case had a Clavien-Dindo grade IIIb complication (ureter injury), and 2 cases had a grade IIIa complication (nephrostomy drainage). After a median follow-up of 19 months, no recurrences were observed. <b><i>Conclusion:</i></b> The laparoscopic, transvesical diverticulectomy is a feasible and valuable procedure with good outcomes. To avoid complications, the ureter needs to be spared meticulously.
