(Introduction) Percutaneous cystostomy is a standard urological procedure; however, very few reports have focused on the many cases of this procedure performed in Japan. We analyzed the background of the procedure and its approach as well as the incidence of its complications at our institution. (Material and methods) We examined 95 patients who underwent percutaneous cystostomy between April 2010 and March 2019. A comparative analysis was conducted for each type of procedure performed. Furthermore, cases that experienced accidental catheter extraction before the first catheter replacement were analyzed, and the three patient groups were compared based on the type of procedure performed and cases that needed another operation. (Result) The indications for cystostomy were urethral stricture (56.3%), neuropathic bladder (13.5%), and prostatic hyperplasia (11.5%). The complications included hemorrhage, peritoneal injury, urinary tract infection, and catheter damage caused by a puncture needle. The overall complication rate was 10.5%. Based on type of the procedure performed, the incidence of hemorrhage was found to be as high as 25% in patients who underwent the procedure using a cannula puncture needle. Accidental catheter extraction before the first catheter replacement occurred most frequently in patients treated with Seldinger technique (17.0%). The rate of complications including accidental catheter extraction ranged from 25.0% to 25.4% among the three groups. (Conclusion) We prefer the Seldinger technique for the first placement of the cystostomy catheter because of its low rate of hemorrhage, but a cannula puncture needle may also be used by using exploratory puncture if vascular damage and accidental catheter extraction are avoided.
