Waiting period for the procedure is 46 days. The ASA 1 category of anesthesia risk assessments dominates as well as the spinal block in the choice of anesthesia. Complications occurred in 34 (12%) patients and were most commonly hematoma, seroma and pain. Fourteen (5%) of them were hospitalized, one of which was reoperated.

Completion of the surgical safety checklist amounts to 76.8% while it amounts to a 100% for the transfering operation list. Direct profit values HRK=984,80 per procedure.
