end-firing fiber at a maximum energy of 1.6 J and frequency of 50 Hz was used. A
26-Fr continuous-flow laser resectoscope (Olympus, Tokyo, Japan) with a 30° down
lens and a mechanical tissue morcellator (VersaCut; Lumenis) were also used.
These devices and settings were used for all procedures performed in this study.
A 20-Fr three-way Foley catheter using normal saline for continuous bladder
irrigation was inserted at the end of the surgery. Generally, the flow of the
irrigation fluid was tapered overnight and terminated the morning of
postoperative day 1. The catheter was removed on postoperative day 2 after
confirming cessation of hematuria. All patients received both prophylactic
antibiotic treatment using cefazolin 30 minutes before the operation and
postoperative antibiotic treatment using cefazolin until discharge.
